I have an Ellipsis 10 (purchased 12/18). For the last couple of months it just randomly reboots and optimizes the apps. I have seen many, many posts about troubleshooting this problem. Obviously, I'm not the only one with this problem. But I have not found any solutions to the problem. I have done all the things suggested (factory reset, soft reset, delete apps, etc) and none work. Has anyone found a solution to this problem? Unfortunately, the warranty ran out in December and I'm stuck paying for a tablet that is totally undependable.
