Speed up your Nexus 7! My Nexus 7 was running very slowly on Android 5.1.1 Lollipop. I’ve tried to hard reset the tablet several times, but after a couple of weeks it became very slow again with even 2 apps installed.
I followed the 2 steps from the following video of “Abs Recon -Solutions”. The Dynamic Gesturing option wasn’t available on my tablet, but disabling Gesture Typing worked perfectly fine!
