I toggled the kinscreen off and then on and then covered the proximity sensor (so the word proximity went and stayed red) and slowly counted to 20. The screen stayed fully lit.
Then I rebooted the phone and tried again with the same result. Then I toggled kinscreen off and on and tried it again. Proximity goes red, but the screen stays on is what I am seeing in all three scenarios. The app worked great on my Galaxy S3. However on my LGG3 (model VS985) the word proximity goes red but the screen does not go out. This is with the settings for timing as I stated above 30s, 5s and 10s.
Okay, I cleared defaults uninstalled the app. Then I downloaded a new copy from the playstore and set the settings as follows 60s, 10s, 10s check on ignore no check on charging or stay bright. Held the phone made sure not to touch the screen and covered the proximity sensor without touching the screen then counted to 20 slowly... still no luck toggled and tried again same result.
