UI system is not responding
I had this error on and old Galaxy Tab A once, but never this device. This may help though. First, if it gives you the option to retry, click it. If that doesn’t work, manually turn it off, leave it for 10 minutes or so, then turn it back on. I apologize if this solution does not work.
