I thought it would be a great idea to install a battery saver ... no such luck. After installing it, the screen went black within 5 seconds although display is set to never sleep. I tried to change the settings, but that didn't help. Also after uninstalling the app, the screen kept on going off within 5 seconds. I was forced to perform a Factory Reset to regain control of my preferences. Otherwise I have been an Avast supporter for years (although as a pensioner I cannot afford to go Premium).
