I have bought a Nokia 5, Android 7. Now I would like two options:
Having the screen darkened to save energy after 15 seconds or when clicking a widget icon on the home screen.
Getting it light again with a double click on the screen.
Having the screen locked for security reasons when I click on a another widget icon on the home screen.
Having it unlocked by double clicking on the screen. Then regarding to my security settings I need to enter the pattern or PIN.
Which screen saver / locker app from the google play store does this best without using much data or energy and still is trustable and does not want to many permissions?
I would be happy about clear, experienced and competent help.
1. Having the screen darkened to save energy after 15 seconds or when clicking a widget icon on the home screen. Getting it light again with a double click on the screen.
Do check out this 3rd Party application called 'Wakey'.
You can configure this app to brighten / Darken the screen on clicking the Widget on home screen.
On clicking the widget again, It goes to normal mode.
It can also keep the screen on indefinitely if needed.
Thank you both of you. I also found a way for each purpose.
I use Nova Launcher now which has a widget with actions including screen lock which darkens. The home button lightens again without having to enter a password.
Power button locks and password is needed when pushing home button agian.
