We love fiddling around with our devices. Yet, at the end of the day they are phones and are expected to make good quality phone calls. iPhones do usually this part pretty well. We would not say it is the best device out there when it comes to placing good phone calls but it does the job really well.
Yet most of us are very cautious of the signal strength on our iPhones and would like to know the exact value of the signal strength as the bars can be sometimes be very misleading. So how to see this, without having to jailbreak your device? Well, here is the step by step of a very simple process that you can do with your iPhone to know exactly the signal strength of your device exactly.
Step 1) Open the dialer on your iPhone and type in : *3001#12345#* and press call.
Step 2) You have now entered the Field Test mode of your device and you would see that on top left of your device where there were bars indicating the signal strength has been replaced with the exact numerical value of the signal strength. Now in case you want to toggle back to bars, you can just press the home button and exit the field test mode and the bars would reappear. Now in case you want to stick to the numerical values and show you are geeky enough to the world, then there is a simple process for that.
Step 3) In case you want to stick to numerical values, just press the power button for a bit when inside Field test mode and wait till the warning to slide to power off appears. Do not power the phone off, but press the home button long enough on your device till it exits to the home screen. Now you will see that the values of signal are now in numerals. Do note, the closer the value is to zero, the better is the signal in your device.
Step 4) Once you have made the numerical values permanent and want to go back to the bars on the top left of your device, then you can type in the same code *3001#12345#* and press the home button which would take you out of the field test mode and restore your device to the way it was.
It is all a very simple and easy trick to perform on your device with absolutely no risk involved. So go ahead and let the geek juices flow into your iPhone. Do let us know how did you find this trick by commenting or tweeting in to us at @Blogtechnika or @Techverarp.
