There are a few things you can do to stop your Android screen from dimming, but it’s important to be sure that you’re doing them correctly. Here are three tips:

  1. Make sure your Android phone is turned off and unplugged when you want to dim the screen. This will help keep the screen from turning on accidentally anddimming unnecessarily.
  2. Use a lightening bolt or other electrical device to turn off your Android phone’s power supply (or use a wall wart). This will also help prevent the screen from turning on accidentally while it’s unplugged.
  3. Use a low-voltage wall wart or surge protector if you want to dim the screen using an electrical outlet instead of a lightening bolt or other device.
