Android Central Question
I have six NID-1002 tablets linked/synced.,four of them are only 1-3 months old . Every day at least one of the four has sudden battery drain to 0% then shuts down and starts constant boot loop cycle . I've tried numerous electric wall outlets //adaptors/USB cords that are for these model tablets. As soon as I get one back to working properly after a day or two of trying to fix it , about an hour later or so one of the others will develop the same issue. Today it happened to two of them almost back to back. This is getting very frustrating and annoying. Plus my SanDisk 32GB micro SD cards keep un-mounted at random. One of these tablets doesn't even have a SD card and still get "unmounted error" message. Can someone please offer a sure fix for these issues? Thank you in advance for a permanent solution.
