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

Hello @Papirin411,

I am sorry to hear this is happening with the device at this time. I would be more than happy to assist! Our first step would be to check out our Device Help Tool and click on the make the model >Then Tutorials > Learn & customize the home screen. This will give you the steps by step on how to manage the home screen. If this is still happening after completing these steps, our next option would be to use our Troubleshoot and Resolve Tool; this will give additional options for Screen troubleshooting.

I hope this is of help to you!

Greetings @Papirin411!

I can definitely understand how doing the warranty process and having to wait for the new device to ship is troublesome. This is a process I have done myself in the past. I will be more than happy to assist you with the warranty.

In order to process a warranty you will want to click on this link. Once processing there will be an option for express shipping which is $14.95 and it is added to your next bill. It will take 1-2 business days to arrive with this method.

Thank you and have a wonderful rest of your day!

I have this problem too, after receiving an OTA update to Android 7.7.1.  (This happened yesterday 9/28/2017).

The tablet was working perfectly previously.  (Why did I accept that update!??!).

Now, even though I have sleep set to 30 minutes, the tablet will dim the screen after 5 seconds and then 1 second later it will be asleep.  There is no setting that prevents this.  

If I watch youtube, it will stay awake till the video ends, and then 5 seconds later it will fall asleep.

I can never take my fingers away from the screen, even to read a web page, because it will go dark and sleep in 5 seconds unless I tap somewhere on the screen every 5 seconds.  

This was a disastrous update.  I may have to do a factory reset.

Same problem here after the "update" last night. After trying powering off and restarting with no success, I did a factory reset and that seems to fix it. What a pain! I think I'll wait a while before doing any updates again.

@MDtrek:  What Android version are you on after the Factory Reset?

Did it set you back to before last night's update - (and set you up for another update to the same problem release soon?)

@AT&T:  Can't you pause this update till you get your QC people looking into this?
