Is your android device running slow from time to time?
Just download the Boost Locker. You don't even need to take time to speed up you device, since when you click to lock your screen, the clean work, the speed-up work and boosting work are all done.

When you give one click on Boost Locker, you get all these work done:
● clean your device memory;
● speed up your device;
● boost running games and other apps;
● lock your screen;
● turn off your screen.

The Boost Locker can release your device from frequent clicking on lock screen button. And before every screen lock your phone can get auto maintenance, get prepared to serve you well before you use the device next time.

Note that:
Uninstall: you have to go to "Settings—>Security—>Device administrators" to shut off Boost Locker first.

Download this Boost Locker.
