My Elipsis 8 tablet is suffering from a bad case of "perpetual destructive app optimization". Every time it is turned on, plugged in, or just left unattended for a while, it reboots itself, and starts an app optimization cycle. This takes hours, since it apparently hangs up every time. Once it eventually gets unwedged, some of the memory is now *gone*: the amount of memory used and unused is lower than before. It then repeats this, again, the next time it is turned off, plugged in, or left unattended. Eventually it gets so low in memory that I need to do a factory reset, which merely restarts the cycle. How do I fix this?
