Keep Screen On

First rate app that does exactly what it says on the box. Simple operation, no bloatware, & no intrusive ads! - when in operation, the app leaves a small notification in the notification/status bar (top left of the screen). On some devices, it also leaves a small badge on the app's icon; but only when the app is turned on... These notifications are unobtrusive but make it difficult for you to forget the app is active & accidentally leave the device on & drain the battery. Great app 5 stars *****

Galaxy S9 on AT&T's network. I download and installed this app on the advice of Samsung's Tech Support. The problem it was supposed to solve is that while I'm on a phone call, using either the Speaker or a bluetooth earpiece, after 10 seconds the screen fades to "gray" and after 30 seconds it goes black. Really annoying, and guess what? Whatever "feature" this is for this phone, this app does not override it. Sad. Yes, it does override the setting for the main display - but that is useless.

Exactly what I needed. Works as described. Simple, free, no ads, no permissions, small app. Note 9 Android 10. Now the boring details. No bells. No whistles. Open it, tap the screen. The image illuminates and the screen stays on until you disable it. Simple. If you are having trouble with it working after updating to Android 10, try uninstalling it then reinstalling it. Easy quick and may solve your problems. Worth the time since this is the best and simplest stay awake app I have used.
