Sometimes the most trivial apps are the most useful's.
Like Keep Screen On.
What it does is simple: It keeps your Android phone screen on to run apps like games, clocks or anything without the screen getting turned off automatically.
Especially on those phones which can't be set to "Screen timeout forever" it is very neat to have this. But for all other phones too. It gives a an easy to reach setting per app!
It's a thing you will never be without if you have a need for it.
Btw. if you have a Huawei or Honor, don't forget to turn off the battery optimization for this app. Otherwise the system itself might close "Keep Screen On".
You can get it in the Play Store for free without ads! Nice!
