I have an elderly Samsung Galaxy Tab 2 with 8gb of storage and 1gb of RAM. It gets by as long as I regularly clear recent apps and RAM (there's a widget for the latter).
On Saturday, touching the recent apps button produced a black screen and the message "System UI has stopped". Everything came back to normal after a moment. Repeated attempts produced the same problem.
All the advice is the clear the system cache, which can be done from Settings|Storage. I did that, but it made no difference. I also figured a factory reset wouldn't hurt, so did that as well. I now have about 500mb more storage than I did and the device is considerably more sprightly, but the crash issue persists.
I've also tried booting into Recovery Mode and clearing the system cache from there, but doing that produces an error (the message is, unhelpfully, "Error!"). Doing it from Settings doesn't produce that.
The device still works, but the problem persists. Does anyone have any ideas? The thing is out of warranty and I'm not going to spend money on having it fixed.
