After doing a factory reset on my Samsung Galaxy Ace 2 I had a smart stay icon appear in my notification bar. The phone never had smart stay before the factory reset. Android version is 4.1.2, both before and after factory reset. Also, when trying to find settings about it, there are no settings to be found anywhere that correspond to smart stay.
I have been looking for a new alarm clock, one that is smart and will wake me up when I am not in a deep sleep at all. I looked on Google play and found some apps that do just this. But most, if not all of them require me to start the app, and leave the tablet on all night. With the screen on, but dimmed to a low point.
I set my phone down for the night and screen goes black. Fine. BUT inevitably every night, regardless of screen timeout settings, I wake up and see the screen light is shining bright... There've been no calls or messages. It comes on for some reason and stays on.
I turn it over face down for all night. I get up in the wee hours there it is: on, shining bright no auto shutdown of screen light.
Q1. If I did not touch the phone screen for some time, it will become black (sleep). How do I wake the screen up (make screen light up) and stay on the same screen? I can press the home key to make the screen wake up (light up), but that may cause the screen that I was last working on disappear and bring me to the home screen.
