    Have screen timeout setting set to 5 min. I think that is supposed to work if nothing is being done on tablet. In my case no matter what I am doing at 5 min it either locks up or goes black and have to do soft reset. Have lock screen set to "swipe". Can be in the middle of typing and if it is 5 min poof it is black screen of death.

    Welcome to AC.

    Make sure you don't have a Never setting in screen timeout.

    Also, make sure you don't have a Smart Screen setting, that keeps the screen on as long as your face is detected.

    Have Galaxy Tab 4 10.1 which just upgraded to Lollypop. This is when problem started. Had screen Timeout set to 5 minutes. (there is no "never" setting. I also changed screen lock to "none". Will be using tablet then screen just locks. Tap, swipe or buttons will not do anything. Let is set and nothing happens. Do soft reset and start from scratch. Sometimes the screen would just go black. Finally realized it was happening not by what I was doing but it was the time in use, 5 minutes and BAM screen black or lock.
    Turned the screen back on to swipe and set the timeout to 30 minutes and I can get work done or read emails, if I do it in less then 30 minutes. Would rather have it set to 5 minutes. As in my original post I thought the timeout was to act on non-use.

    Did YOU upgrade it (download a file and flash it)? Then install Lollipop again from scratch (backing everything up first, because you'll lose everything).

    Or did your carrier update it over the air? If that's the case, bring it in (back it up just to be sure) and ask them to fix what they broke.
