Time out

[Cats]

Please could someone advise me regarding my Xperia Z tablet.  Yesterday the screen has started to go dim and go off after a few seconds of not touching it, I then have to press the switch on button to get back. I set the tablet to "never" close down when I set up the tablet and I checked my AVG anti virus  and that's also set as "never" close down. This is the first time this has happened to me. I would appreciate some advice please. Many thanks.

Hi Cats. 

Welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

With the information supplied, I can advise that this is more likely related to a third party application. I suggest going through any newly updated or downloaded applications and checking their settings.

Third party applications can change the way the tablet works, they simply override the tablets settings.

I hope this helps.
