The Nexus 7 (2012) received the Android Lollipop firmware a while ago. Sometimes the tablet became very slow or even unresponsive. The following measures might help revert those issues. That topic is already covered quite thoroughly by lots of other blogs and websites. Still, I wanted to write down the actions that helped me bringing back my Nexus 7, even if it’s just for private documentation purposes.
Clear app cache
This can be done simply by pressing some buttons:
- Turn off your device
- Press and hold Power and volume down buttons simultaneously until you see a large arrow at the top of your screen.
- Press the volume down button repeatedly until you see “Recovery” in the arrow.
Select it by pressing the power button.
- You’ll see an android mascot with a red triangle and exclamation mark.
Hold down the power and press the volume up button once and then release the power button.
- Press the volume down button repeatedly to select “erase or wipe the cache partition” from the list of options.
- Wait for the process to complete and then restart your device.
It doesn’t make sense really but I found, turning off auto rotation speeding up my device significantly.
Some say setting the keyboard theme to “Holo Theme” also helps.
Disable gesture typing
Go to Preferences -> keyboard settings -> gesture typing. There turn off dynamic floating preview. This seems to have an huge impact.
Upgrading to Android Marshmallow
Currently my Nexus is running Android 6.0. It has a view minor glitches but in my case works quite well. Speed is much better and the battery drain is reduces as well. If you’re interrested I’ve covered the upgrade in another Article: Working Android Marshmallow (6.0) for Nexus 7 (2015) – Update 2
