I’ve found that using an app that simulates a reboot can be very helpful in increasing the performance of my Android devices.
I use Fast Reboot. I use it on both my Android smartphone and tablet as I hate waiting for my devices to reboot. With Fast Reboot, I rarely have to perform an actual reboot and they’re quickly back to their peak performance.
This doesn’t require you to root your device. It’s much faster than a physical reboot, clears memory and keeps your Android device running smooth.
