Samsung Galaxy Nexus despite being now a couple of years old is a stellar smart phone. The Nexus 7 too, despite being overtaken by plenty of new tablets is a very good choice when it comes to 7 inch tablets. However, one thing that is a common denominator between these devices apart from the Nexus generic name is that they both have lag issues. The Nexus 4 is much better when it comes to the whole lag issues but these older devices seem to be plagued by non responsiveness. One way to solve the issue is rooting the device, changing the ROM and Kernel and panic in case something goes haywire. However, one user on Reddit has come up with a possible solution right out of the box for the device.
This is what he has written in his thread:
“I noticed the lag thread that was getting popular. In fact, I’ve been experiencing the same thing with my GNex for a couple of months. Here is what helped me personally: Limit your background processes to 4 or less under developer options.
I’ve known for some time that small random writes on the GNex is incredibly slow from storage benchmarks, and failing flash memory probably doesn’t help. The latest JB seems to like using all available RAM by caching recently run apps in memory. In theory, when you need to clear more memory for a new app, some of these caches would be deleted to make room and the transition would be seamless. In reality, due to slow IO processing, this clearing process makes the device extremely laggy. Limiting background processes ensures you always have available RAM.
From my experience, this will not affect you much unless you are a heavy multitasker. Notifications are not affected as they are classified as running apps, not background processes. Personally I limit background processes to just 2. This method may or may not help you, but I really don’t see any harm in giving it a try.
Note: If you can’t see the setting, go to about phone and click on the build number repeatedly. Also, the background process limit is not preserved across reboots for some reason. Finally, you can use Greenify to hibernate apps, freeing even more RAM.”
We did try the method out on our GNex and although there was little drastic change, things were much better than they were originally. So we do urge our readers to try this out and see if the issue can be resolved on your device.
