ANDROID HAS A VAST number of features in settings, but there are more hidden away from users.
The main one is Developer Options, a feature used to help app development on Android, and it has a few interesting features.
One of them allows your screen to stay awake while you’re charging, which can be useful if you’re keeping tabs on something on-screen and your phone keeps going into sleep mode.
To start, you’ll need to activate Developer Options. If you haven’t done this already, you can access it by going into Settings > About phone (or Settings > About > Software Information > More for certain devices) and scroll down to Build number.
Start tapping it a few times and eventually it will tell you Developer Options is now available.
Now if you go back to Settings, the option will be available. Go into it, and turn it on. The stay awake option should be one of the first things you’ll see on the screen.
Developer Options is a long menu of features but they’re hidden away for a very good reason. Messing around with them isn’t recommended unless you absolutely know what you’re doing and even then, you should keep it to a minimum.
Also, while you can do a similar thing by changing the sleep setting in display, this option only keeps your screen on constantly when you’re charging it.
Changing the length of time it takes for the screen to sleep happens regardless of what your phone is charging or not, and is less convenient as you have to change it back when you’re finished.
