[Q] Screen staying on after notification ? topic

So I just recently switched from iPhone to a AT&T Note 4..been fiddling with the settings and seem to of got everything how I like it..but whenever I get a notification of some sort the screen Will stay on until I attend to the power button. Does anybody know the possible cause ? My screen time out is at 30 seconds..checked developer options and the stay awake feature is disabled. Not sure whatsoever of what could be causing this

Android play store installed apps not staying in sync topic

I'm not sure what the right terminology is here, but each time after I install a new rom and log into the play store, it starts to download my previously installed apps. The problem is, it's like a month behind. I'm not sure how to force the android store to stay in sync with what's actually installed on my phone. (I'd like to avoid having to go find all of my apps each time I flash a new rom).
