Charge upto 40 Different Phones with this amazing Wireless technology

Wireless charging is the new blue tie of the tech fashion town. While the major companies are still battling to secure one standard for wireless charging that would be universally accepted, there are plenty of new applications of the technology emerging already. However, so far we have seen applications of wireless charging used in places like car charging or on desk, but one thing that has been common in all these have been that you need some sort of contact between the backplate of the phone and the charger.

power Zones

But what if, you could charge the devices, plenty of them, without the need of any physical contact. That is exactly what some of the folks in Korea seem to be experimenting with. It is technology like this that truly will revolutionize the way we charge our phones and perhaps also go a long way in helping us clear the clutter on our desks keeping the desk cleaner. The people at KAIST have developed a technology where you can charge up to 40 devices as long as the 40 devices are 5 meters near the base station. The prototype can not just charge phones but also help you power fans and televisions etc, making it a pretty revolutionary prodcut.

The makers of the technology believe, just like Wi-Fi Zones, such power zones will be a massive part of the future. You can check out the detailed working of the technology in the video here:

Why Should you not Hammer the Battery of your Smartphone?

We have seen several videos uploaded on Youtube where the host hammers the bejesus out of the smartphone to test the toughness of the device. Although this is never indicative of the real life scenario, as nobody goes on to hammer their devices, but it does give a window into the world of how the device would stand up against the brutal forces of nature. When TechRax recently uploaded the following video on Youtube which was a knife and hammer test of the newly announced Galaxy S5, little did anyone know about the most significant part of the video will not be how well the device stood up against the brutal forces. You must check out the video first:

Now, if you are done seeing that S5, like any other device succumbed to the hammer shots, rewind and watch the end of the video. You could see when the user hit the battery with hammer straight up, the battery kind of inflated and started emitting a gas out. The reason for this is that Lithium ion cells which are used inside the battery of smartphones are not safest when under extreme pressure. These batteries are sealed under high pressure, and when hit, this creates a crevice or dent in the device which emits the electrolyte. This is certainly dangerous for your health and in case you happen to inhale this, it could be hazardous. So, in case you plan to do a hammer test on your device, make sure you do not hit the battery with hammer hard.

See What went into Designing the HTC One (M8)

As well designed as the HTC One M8 is, it is a pity they could not agree on one final name for the device, well, yes, that is the joke some of the rivals of HTC are being forced to make, even them conceding that the device is one of the most beautifully designed smartphone out there. The HTC M8, thats what we will refer to it, for shorts, is an upgrade from the last year’s success that the HTC One or HTC M7 was. The device is more than an incremental update unlike Apple moving from say an iPone 4 to iPhone 4s. A lot more thought and subtle changes have gone in, including a completely redesigned chassis.

It is clear the main design challenge before HTC was to take something that was already good and make it even better. Yes, indeed, improving the design of the M7 is a real challenge and apart from making the internals more powerful, a lot more went into designing the M8. For example, the new depth measuring camera came into picture as well as a larger battery and a bigger and improved amp for the boomsound speakers. So how did HTC tackle the problem, what was the process of making the world’s most beautiful smartphone, here is a video HTC have released giving you a sneak peek into what they went through developing the device.

PS IV Dual Shock Controller vs PS III Dual Shock Controller

As we stare at the calender intently and wait for it to turn to November 15th, time could barely move any slower than it is right now. The special thing about November 15th is that, it is the date when Sony’s latest flagship Gaming Console the PS IV goes on sale in the US. It is slated for a European release a couple of weeks later.

PS IV vs PS III Controller

While plenty has been written about the new console and how it stacks up against the major rival XBox One and how Sony has an initial headstart on Microsoft thanks to the Redmond based company dropping some absolute clangers when it came to DRM policies which eventually had to be reversed, not enough comparisons exist to what would be like to use the PS IV over PS III.

Hence, we thought of sharing across a video that a gamer has shot for about 5 minutes which compares the PS III DualShock controller to the one on PS IV. No doubt, the newer model is sleeker and better looking but one major aspect of the PS IV DualShock that has been a rather requested feature is that you can charge the controller while the device is in standby. Apart from that, there are some key differences as well as similarities between the two controllers, make sure you check the video below to know all about them:


Which Human Body Parts can unlock the Touch ID on iPhone 5s?

The Touch ID or the biometric sensor on the iPhone 5s is one of the major attraction of the new iPhone. Alongside the new Camera sensor, dual LED flash and the 64 bit architecture, the Touch ID has left a lot of mouths gaping for thin air. No wonder the iPhone 5s is one of the most talked about devices on the planet currently.

iPhone 5s unlock

However, have you ever wondered that apart from your figures, there could be other parts of your body that can unlock the iPhone 5s too? It is an interesting question given that we all love to experiment out with things and come up with solutions that are totally going to blow the mind of people. Mashable have done something very interesting and put the iPhone 5s through a series of tests trying to find out the body parts which respond to the touch ID and to our surprise, there are more than one body parts that do.

Just to give you a hint, would you like to use your forearm to unlock your iPhone? Here is the entire video for you:

Watch the Entire Apple iPhone 5C and 5S Keynote Here

It was a rather odd decision that Apple did not stream the Apple event live when they showcased the iPhone 5S and iPhone 5C. They general view was that the event was a rather low key affair and conducted within Apple’s own headquarters instead of a proper theater or auditorium. Apple wanted to keep the event small and cozy and more old school like. As a result most of us missed out on watching the show unfold live and unless you were present at the venue, you were relying on live text feeds coming in from one of the tech blogs which were present at the venue.

iPhone 5c

However, if you want to relive those moments and see for yourself how the new iPhones were released then Apple have already released the recorded video from the event. You can watch it right here. You will notice that this was one of the shortest keynotes Apple has ever delivered and they did mention it more than once  that you might have already seen these products leaked online and were really in no mood to sit and repeat on things that just about everyone know.

Check out all the Features of Samsung Galaxy Note III in the Official Video

The dust has barely settled on all the announcements of IFA and despite it being almost a week now the Samsung Note III is generating the same sort of buzz that it did at release. Some of the people are still puzzled how a device of such a mammoth size continue to please the aesthetics of people while some are already counting their saving down for October which is when the device is expected to go on sale. It is not difficult to find out more about the Note II in case you missed out on the live event.


The device features a 5.5 inch Full HD Display now with Snapdragon 800 SoC in most of the US variants There is 3 GB of RAM in the device while the stylus or the S Pen has some nifty cool features. Now, when you press the screen with the S Pen you get this half radial menu where you can pick options from. Plenty of tech analysts are saying this is exactly the same feature as seen in the Paranoid Android ROM an Samsung have simply taken the feature and added to show the menu when S-Pen is touched to the screen.

However, if you would like a full in depth video of all the features of the Samsung Note III, then here is an official video released by Samsung which shows off all the tricks this phone is capable of, though dare we say, most of them are exactly the features we have already seen on the Samsung Galaxy S IV. Anyway, for your curiosity sake, here is the video:


Moto X Scratch Resistance Tested Against Knives and Hammers

Although obviously nobody subjects their expensive smartphones to knives and hammers or anything that is remotely close to damaging them, it is always nice to know how the device will react in case the worst situations did come true and the phone had to face some tough conditions. This could be a major fall or even simply wear and tear over a period of time. Moto X has been one of the best Android smartphones of the year 2013. Despite all the customizations the Moto X remains a smart phone made largely out of plastic. No, we do not really buy into all the polycarbonate stories, simply because our Engineering Degrees tell us polycarbonate is only a fancy name of plastic.

Moto X Scratch test

So, what would happen if the device is put through some of the toughest tests? Would the Moto X stand it or simply crumble under the pressure and we would have multitudes of scratches and broken back panels? Here is an interesting YouTube video produced by PhoneBuff where the Moto X is scratched brutally by a knife and a hammer.

Honestly, we were surprised by how well the device stood up to the impact tests, especially given it is pretty much plastic. The device still worked and that for us makes the Moto X definitely a lot more desirable device than before.

Are you impressed with the performance of the Moto X? in handling the scratches and impact? Let us know in the section below.

How to Clean Dust From Inside iPhone 5 Camera Lens

As we use devices over a period of time, they tend to gather plenty of dust. This may be simply dust from the atmosphere or a result of lying inside our jeans pockets. It is possible to physically wipe out most of this dust using a tainted cloth from the screen or the back of the device, however, one place where dust really becomes a proper headache to remove is from inside the Camera Lens.

iPhone 5 Lens cleaning

It is extremely important to make sure there is no dust in your camera lens as these dust particles can cause diffraction of light which could result in some crazy after effects, most not desired, in images that we shoot. For a device like iPhone, it is pretty much impossible to clean the dust easily as the lens is pretty much in line with the surface of the device and as a result the task is a little complicated.

However, an interesting video on Youtube gives a step by step procedure on how you can easily remove dust from inside the lens of your iPhone 5. however, a word of caution. This method involves opening your device and getting to the internals of it, so if you do not want to void the warranty of your phone or do not have the confidence to do it, stay away from those tempting screws of the iPhone 5. Here is the video, in case you are feeling adventurous or if there is too much dust in your iPhone 5 camera lens and you really need to get rid of those minute particles.


iOS 7 Beta 5 is Here

Apple has been rolling out the Beta updates to iOS 7 thick and fast. Only last week we had the release of iOS 7 Beta 4 and things are looking a lot better than the Beta 1 which faced a lot of backlash from the Apple lovers and haters alike. Things are moving smoothly as we head into fall and possibly a release of iOS 7 alongside the iPhone 5s/ iPhone 5c, whatever they will call it. However, late last night, Apple released the iOS 7 Beta 5 which once again comes with a few changes. There are changes to the logos of a few apps like mail with the shade being reported going a little lighter as well as obvious bug fixes and performance enhancements.


You can also check out the video walk through of all the changes here:

The entire change log is as follows:

Notes and Known Issues

The following issues relate to using iOS SDK 7.0 to develop code.Address Book


The classes in the AddressBookUI framework now explicitly disallow subclassing. For apps linked against the iOS 7 SDK, attempting to initialize a subclass of one of these classes returns nil. For apps linked against older SDKs, the only behavior change is a warning logged to the console.

As of Seed 4, privacy support for the AddressBookUI framework is reenabled for apps linked against the iOS 7 SDK. Apps linked against older SDKs are not changed. If your app uses any of the Address Book view controllers, you should verify that it still behaves as expected.



AirDrop in iOS 7 Seed 2 or later is not compatible with AirDrop in iOS 7 Seed 1.

Contacts Only support requires that:

You are logged in to iCloud.

The sender and receiver have each other’s Apple ID email addresses in Contacts on their devices.

Fixed in Seed 5

Contact Only currently requires that you have an active Internet connection.

The App Store should support the ability to ?nd an app capable of opening a received document based on the document’s Uniform Type Identi?er (UTI). Currently, just a blank screen is displayed.

AV Foundation


AVCaptureSession now uses your app’s AVAudioSession by default.

Core Animation


When the UIViewGroupOpacity key is not present, the default value is now YES. The default was previously NO.

This means that subviews of a transparent view will ?rst be composited onto that transparent view, then the precomposited subtree will be drawn as a whole onto the background. A NO setting results in less expensive, but also less accurate, compositing: each view in the transparent subtree is composited onto what’s underneath it, according to the parent’s opacity, in the normal painter’s algorithm order.Exchange


In Seed 4 and later, the Exchange DeviceIdenti?er has been changed back to the behavior of iOS 6 where it uses the serial number.



New font line heights were introduced in Seed 4. If you had manually aligned your font in earlier seeds, it may move slightly up vertically in later seeds.



An NSMetadataQuery with ubiquitous scope can now use kMDItemContentTypeTree in predicates.

For example:

NSPredicate *p = [NSComparisonPredicate





modifier: NSAnyPredicateModifier



When called on results returned by queries with ubiquitous scopes, -[NSMetadataItem

valueForAttribute:NSMetadataItemDisplayNameKey] now produces the same value as –

[NSURL getResourceValue: forKey: NSURLLocalizedNameKey], matching nonubiquitous




If you use iCloud Keychain with recovery, you may see a dialog indicating recovery has been disabled due to a server change. This is intentional. To reenable functionality, follow the instructions in the noti?cation. If you see multiple alerts or observe issues with reenabling recovery, please ?le a bug report.

iCloud Keychain in iOS 7 Seed 3 or later is not backward compatible with iOS 7 Seed 2 or OS X

Mavericks Seed 2.

If you had iCloud Keychain and/or Keychain Restore enabled from iOS 7 Seed 2, both features are disabled upon updating to iOS 7 Seed 3 or later.

After updating to iOS 7 Seed 3 or later, go to Settings > iCloud > Keychain and reenable iCloudKeychain on your devices.

See OS X v10.9 Release Notes for more details.

Activation Lock, a new feature of Find My iPhone, is turned on automatically when Find My iPhone is enabled on any device running iOS 7. Activation Lock requires users to enter their Apple ID and password to turn of Find My iPhone, sign out of iCloud, erase the device, or reactivate the device after an erase. It’s important to do one of the following before transferring a device to a new user:

Sign out of iCloud.

Turn of Activation Lock in Settings > iCloud > Find My iPhone.

Fixed in Seed 5

Voice Memos are not restored from iCloud Backups.

Users in Switzerland, France, Spain, Germany, Poland, Finland, and possibly some other countries, will be unable to restore their keychains using phone number validation.

Known Issues

Password ?elds are not displayed in alert views for apps in landscape (for example, Game Center authentication or In-App purchase). Text entry still works, though you can’t see what you are typing.



If the calls to renderInContext on the layer backing an MKMapView are made of the main thread, they should be eliminated or moved to the main thread. Failure to do so can cause an app crash.

Instead of using renderInContext, use the new MKMapSnapshotter APIs.



iOS now remembers the last used media app across reboot and app crashes. Media apps that can receive remote control events should be prepared to be launched in the background and potentially receive a remote control event to begin playback. Additionally, it’s important that media apps monitorand handle the media server reset event, since the media app may receive a remote request to resume playback after a reset. Noti?cations to monitor these media server events are available in

AVAudioSession and proper handling is described in General recommendations for handling


Multipeer Connectivity


Many updates to the MCSession APIs are included in this seed. The APIs now function as they were presented at WWDC. Major changes and enhancements include:The following new method on MCSession has been implemented:

– (NSOutputStream *)startStreamWithName:(NSString *)streamName toPeer:(MCPeerID

*)peerID error:(NSError **)error

This delegate method has been implemented:

– (void)session:(MCSession *)session didReceiveStream:(NSInputStream *)stream

withName:(NSString *)streamName fromPeer:(MCPeerID *)peerID

The following new method on MCSession has been implemented:

– (NSProgress *)sendResourceAtURL:(NSURL *)resourceURL withName:(NSString

*)resourceName toPeer:(MCPeerID *)peerID withCompletionHandler:(void(^)(NSError


The delegate method to start receiving a resource from remote peer has been implemented as:

– (void)session:(MCSession *)session didStartReceivingResourceWithName:(NSString

*)resourceName fromPeer:(MCPeerID *)peerID withProgress:(NSProgress *)progress

The delegate method to ?nish receiving a resource from remote peer and save the content in a

temporary location is implemented as:

– (void)session:(MCSession *)session didFinishReceivingResourceWithName:(NSString

*)resourceName fromPeer:(MCPeerID *)peerID atURL:(NSURL *)localURL withError:

(NSError *)error

Note: The app is responsible for moving the ?le to a permanent location within its sandbox.

MCAdvertiserAssistant is a convenience class for implementing an Advertiser, which handles invitations and connections to an MCSession.

MCSession has a new initWithPeer: method.

sendResource has added “with” to the completionHandler.

The timeout has been removed from connectPeer:withNearbyConnectionData.

For more information on these APIs, watch the video for WWDC 2013 Session 708, “Nearby

Networking with Multipeer Connectivity.”



AVAudioSession can no longer become active by apps in the background that wake due to

Background Fetch, Background Transfers, and Remote Noti?cation events.

The policy for the task completion API has changed back to match the iOS 6 behavior, but the time limit for task completion has decreased from 10 minutes in iOS 6.


The cellular fallback technology present in previous seeds has been removed as of Seed 5.

Two low-level networking APIs that used to return a MAC address now return the ?xed value

02:00:00:00:00:00. The APIs in question are sysctl (NET_RT_IFLIST) and ioctl

(SIOCGIFCONF). Developers using the value of the MAC address should migrate to identi?ers such

as -[UIDevice identifierForVendor]. This change afects all apps running on iOS 7.

Objective-C Runtime


Due to changes in how the isa ?eld is implemented, *self may change during enumeration (for

example, if the container is retained).

Workaround: When implementing countByEnumeratingWithState, do not set state-

>mutationsPtr = self.



As of iOS 7 Seed 4, Passbook has added support for the major and minor ?elds to better match the

rest of the iBeacon ecosystem. The new major and minor keys are independently variable optional

alongside proximityUUID (required) in each dictionary in the beacons array.

In previous versions of the iOS SDK, Passbook did not validate the back ?elds on passes

completely. The validation rules have not changed, but validation is now including back ?elds.

Please check the console log for additional logs.

As of iOS 7 Seed 3, PKPassLibraryDidCancelAddPasses is a new status code in the

PKPassLibraryAddPassesStatus enum. It signi?es that the user tapped Cancel in an add-passes




Upon upgrading from an earlier seed, photo thumbnails in the Photos app will not appear for a short



Fixed in Seed 5

Upgrading to iOS may reset Safari’s settings to their default values.


-[UIDevice uniqueIdentifier] is no longer accepted in submissions to the App Store. In iOS 7,

apps that are already on the store or on users’ devices that call this removed API will no longer be

returned the UDID. Instead, -[UIDevice uniqueIdentifier] will return a 40-character string

starting with FFFFFFFF, followed by the hex value of -[UIDevice identifierForVendor]. It is

important to consider how this will afect existing apps. Consider submitting updates that no

longer access the UDID.

iOS now requests user consent for apps to use audio input on all iOS 7 devices. For devices sold in

China, iOS will also request user consent for apps to use the camera hardware. The operating

system will present the consent alert when you set the category of the instantiated

AVAudioSession. The AVAudioSession categories that will present the alert are

AVAudioSessionCategoryRecord and AVAudioSessionCategoryPlayAndRecord.

If the user doesn’t allow access, the audio session data will be all zeros (silence). For devices where

camera access is requested and denied by the user, the video capture session is a black screen.

The API gethostuuid() has been removed and will not be accepted for submission to the store,

regardless of the targeted OS. For existing apps running on iOS 7, the function will return a uuid_t

representation of the vendor identi?er (-[UIDevice identifierForVendor]).


Fixed in Seed 5

The setup assistant may crash when setting up a new device with an existing email address.



This seed includes development versions of new male and female Siri voices for U.S. English, French,

and German.



Through iOS 6, when using TWTweetComposeViewController and SLComposeViewController

(the latter only for Twitter and Weibo, but not Facebook), if the caller supplies a

completionHandler, the supplied completionHandler is responsible for dismissing the view

controller. As of iOS 7, if the app links against the iOS 7 SDK, the view controller will dismiss itself

even if the caller supplies a completionHandler. To avoid this, the caller’s completionHandler

should not dismiss the view controller.

When using the iOS 6.1 SDK on OS X v10.8 Mountain Lion, if you use the iOS 5.0 or iOS 5.1 Legacy

SDK in iOS Simulator, you will not be able to use Twitter features: attempting to sign in to Twitter

via the Settings pane will fail, and Twitter.framework will not work correctly. If you need to test

Twitter features, you will need to choose either an iOS 6.1 or iOS 6.0 Simulator run destination, or

you can test with iOS 5.x on a device.Springboard


Active touches are no longer canceled when the user takes a screenshot.

Dynamic wallpaper is not available on iPhone 4.

Sprite Kit


+[AVPlayer playerWithPlayerItem:] returns an AVPlayer object, but the current item will return

nil if the player was created on another thread.


Fixed in Seed 5

Some iPhone 4 devices are unable to download content from the App Store and the iTunes Store.

Known Issues

App downloads can get stuck in the “Waiting” state.

Workaround: Reboot your device once or twice to resolve the issue and allow subsequent downloads

to continue.



Before Seed 4, the snapshot API (snapshotView and

resizableSnapshotViewFromRect:withCapInsets:) would defer taking the snapshot if the view

had never been committed or had been added to the view hierarchy in the current transaction. This

behavior has changed.

Snapshots now always represent the current, committed state of the view. Attempting to snapshot

a view that has never been committed logs a message and now returns nil.

Snapshotting methods have been updated and now take an argument: afterUpdates. When set to

YES, this instructs the snapshot to wait until all pending changes to the hierarchy have been

committed. To maintain the pre-Seed 4 behavior, pass NO and the snapshot will capture what is

currently on screen. See UIView.h for more details.

When there isn’t enough room in the navigation bar layout for the full text of the back button title,

the navigation bar will substitute a generic short back title (in English, “Back”). If even that string is

too long, the bar will show the back indicator chevron with no title.

+[UIPasteboard pasteboardWithName:create:] and +[UIPasteboard

pasteboardWithUniqueName] now unique the given name to allow only those apps in the same

application group to access the pasteboard. If the developer attempts to create a pasteboard with a

name that already exists and they are not part of the same app suite, they will get their own uniqueand private pasteboard. Note that this does not afect the system provided pasteboards, general,

and ?nd.

Starting with Seed 2, apps default to using the new view controller-based status bar management

system. To opt out of this, add a value of NO for the

UIViewControllerBasedStatusBarAppearance key to your Info.plist.

When using Auto Layout to position a UIButton, if you set the content compression resistance or

content hugging priority to minimum, the button will have ambiguous layout.

Workaround: Don’t use a content compression resistance or content hugging priority of less than

2 for UIButton.

UIScreenEdgePanGestureRecognizer allows you to perform actions in response to swipes over

the edge of the screen using the same heuristics that the system uses for its own gestures. Use this

if you have a navigation semantic of your own that doesn’t use UINavigationController but

should include this gesture (e.g., Safari).

This gesture recognizer has a property that describes the edges on which it’s active. UIRectEdge is

a new enum type that this property and -[UIViewController edgesForExtendedLayout] can

share. UIRectEdge replaces UIExtendedEdge, which will be removed. The members of both have

the same values. Use Xcode to replace all instances of “UIExtendedEdge” in your project with


UIButtonTypeInfoLight, UIButtonTypeInfoDark, and UIButtonTypeDetailDisclosure

buttons all look the same.

Blurred layers are not available on iPhone 4.

Parallax is not available on iPhone 4.

Letterpress text is not available on iPhone 4.

Fixed in Seed 5

Your app’s UI may move slightly after using a media player in landscape mode.

Known Issues

Password ?elds are not displayed in alert views for apps in landscape (for example, Game Center

authentication or In-App Purchase). Text entry still works, though you can’t see what you are typing.



Weather conditions are not animated on iPhone 4.



Previously, when the viewport parameters were modi?ed, the old parameters were never discarded.

This caused the viewport parameters to be additive.

For example, if you started with width=device-width and then changed it to initial-scale=1.0, you

ended up with a computed viewport of width=device-width, initial-scale=1.0.In iOS 7, this has been addressed. Now you end up with with a computed viewport of initialscale=1.0.

Previously, when using <meta name=”viewport” content=”initial-scale=1.0, user-scalable=1?>, the

scale could be incorrect after rotation.

Now, if a user has not scaled the page explicitly, the page is restored to its initial scale. Also, the

current scale is now correctly restricted within the min-scale, max-scale bounds.

Some images for Retina display devices appear at twice the size that they should instead of being

scaled down 50%. This issue can also occur with any image to be scaled that is larger than its

container and that uses either the background-size property or the -webkit-background-size

property. This issue afects both native apps that display web content and web pages viewed in

Safari for iPhone.

The background CSS shorthand property now resets the value of the background-size property to

auto when background size is not speci?ed. This new behavior is per the CSS spec, and the old

behavior is available only for apps linked to an SDK prior to iOS 7.0 when running on iOS 7 or later.

Workaround: Specify the background-size property or the -webkit-background-size property

after the background shorthand property in the CSS stylesheet for the web content being


Web apps and web clips created prior to Seed 4 will not stay in folders across reboot.

Workaround: Delete the old web app or web clip and recreate it in this seed by loading the content

in Safari, tapping the Action button, and then “Add to Home Screen.”



Seed 4 and later include changes to AWDL such that technologies that use it—such as AirDrop and the

MultiPeerConnectivity APIs—will not work properly with older seeds.
