A11+ Screen goes black

Hi Andrew, I sent the old tablet back and got a new one. Same problem. 

I googled the Life out of it, but no information was forthcoming. 

I then went on Amazon, where I got the cover from. Searched the reviews for the cover, and 1 review mentioned that the cover magnet was too strong and affected the sensors in the tablet. Removed the cover and the problem is gone.

Have put a different cover on and all is OK. Old cover going back to Amazon. 

Thanks for all your advice, I thought you might like to know the solution. Cheers buddy 👍 

@Chilly9999: As far as I know, your tablet's orientation should not affect your ability to wake the screen when it goes idle. You may wish to try swiping down from the top right corner of the Home screen > Press and hold on the Auto rotate icon > Toggle on 'Lock screen' > Done. I'd also recommend restarting your Tab A11+ to refresh the software and resolve any temporary performance issues. 

Let me know if this helps. 

@Chilly9999: Are you accessing a particular app at the time, or performing a certain action? Does the screen go dark while you're physically interacting with the touch screen? 

If you haven't tried this already, please head to Settings > Advanced features > Motions and gestures > Double tap to turn off screen, and toggle this option off. 

Also, head to Settings > Display > Screen timeout > Increase the time beyond your current choice e.g 5 minutes > Keep screen on while viewing > On. 

@Chilly9999: No problem. Hopefully this was just an anomaly, and your replacement tablet offers a smoother experience. This isn't an issue that I've encountered before, so I'm fairly confident that you won't encounter it again. I understand that you may have arranged a replacement, but I'd still recommend performing a factory data reset, a suggested by @Star_girl, as this will help to determine if the problem is stemming form an external source, or a temporary software/hardware issue. 

I'll give it a go. Cheers 

@Chilly9999: I see where you're coming from, however if you back up your device via Samsung Cloud and Google Drive (Settings > Accounts and backup) then setting your tablet back up following the reset should be relatively painless. For further guidance, please take a look at the link below.

guyss, i just found out the problem and a solution now as u said the prob IS bec of magnets now the tab have a feature were if u close the cover (lid) it turn off the screen off and when u open the cover (lid) it will turn on now that depends on. now that depends on magnets in the cover lid . on my tablet i found out that this also affect the back so if u put a magnet on the back and the cover do have a a magnet so when u use the tablet while flipped you put the lid back and that causes it to think the lid is closed and that's what make it turn off. the solution i found is you can actually turn this feature off: go to settings advanced features, accessories and there u can see turn the screen on and off by opening or closing the cover i jus turned that off and the problem is gonee.

I got the same problem with A11+ and Targus cover. I turned the double tap setting off, and adjusted the accessories setting. It works perfectly now.

I logged to this page just to give a shout out to Chilly9999 and Issa6 for solving this issue. I couldn't find the solution anywhere else, even on samsung support. Thanks guys.
