Screen on the K88 Tablet goes to sleep or to black in 5 seconds

I'm having the same issue after the forced update last night. This problem renders the tablet completely useless. I've tried all of the suggested fixes listed here, short of the factory reset, with no luck. 

To me, losing all of my installed apps and having to start from scratch is not an acceptable option. If I have to go through the time consuming process of installing dozens of apps, it will be on a new tablet that I purchase from a competitor. 

AT&T needs to fix this immediately.  

The security setting has no effect on 7.1.1 update. The tablet still blacks out after 5 plus seconds

@1daveatatime This does work,  not the best solution but far better than keeping  your finger on the screen all the time. Thanks for posting!

Factory reset didn't work for me. But I found a workaround that will be acceptable to some but not to everyone. I went on the Play Store and found this app, appropriately named Keep Screen On! 

Nice find!

I suspect there are about 6 or 8 such apps, and perhaps trying a few more of them will fine one with better options.

For those contemplating the Factory Reset:  and also 1Dave...

If you decide to factory Reset, be sure to set the applications to backup settings to your google account first. (See settings / backup-restore).

That way when you reinstall most of your settings will come back.

Note that At&t provided a similar functionality, in bloatware, which I had long ago disabled.  I don't suggest that you use that.

Backup pictures, music, chats, etc, as you know already, because the Backup-restore doesn't save that stuff. 

Here's the important part:  When you factory reset, it will offer to reinstall all your previous apps, and should pull all the settings from the above mentioned restore capability.  This DID NOT FIX the problem for me.  Yes, all my apps were restored from the market and their settings were retrieved from google and they all worked (mostly).  However the 5 second shutdown was also restored.  Grrrr.

So I did a second factory reset, and declined the restore of applications.  This did work.  No 5 Second problem.

I then disabled all the bloatware.

Then I selectively restored just those apps I actually wanted.   (After turning on Automatic Restore of settings under Settings: backup-restore).

I took the opportunity to dump apps I did't really use.

So go ahead and try the full-restore of apps if you want, but don't be surprised if the 5 second problem re-appears.  You're probably better off just biting the bullet. 

I quite frankly doubt AT&T will ever fix this problem, and will deny any knowledge of it even when you point them at this thread.

screen will never sleep while charging it says but you still can manually control the sleep with the power button

The problem I have with this is that if that screen ever wakes up while on the charger, (notifications or an app, or whatever) it will never go back to sleep and probably burn in the screen image.  

I don't consider this a solution, merely a stop gap till we get a fix or people just do the factory reset.

Why is this listed as solved? This isn't solved. The problem still occurs. The solution is for AT&T, Android, and ZTE to release a patch. By the way--factory reset didn't fix it. Unlist this as solved, because it is not solved, and the solution post just reiterates that the problem still persists and that no solution has been found.

Although this really isn't the thread for this, I can't help wondering why these days we seem to be losing more and more corporate responsibility. A purchase isn't an endorsement. They're not convincing wanderers in the desert to drink the sand; the people drink the sand because they don't know the difference. The dollar's worth what we believe it to be worth, and it sure as heck is worth a whole lot more than this.
