How can I remove unfortunately system ui has stopped working

To get back in from the black screen system ui provides press button and volume button together.This does not solve the problem just gets you back into the tablet.

I had the same problem but now I solved it myself, it appears to me that no one talks about this method and they tell you to go to settings and blah blah blah!! They do not understand that the screen is black and cannot see anything! Others wants you to do a factory reset and cause you to lose your precious data! I have fully recovered my phone without any data loss!

I had the same problem. but by trying to hold different buttons at the same time my phone restarted, and by doing that it fixed it.

only for the hard rest on power on batan and the waliam batan ap ya down open this next page enter option rest and next option no…no..no.yah yes option batan canfam batan yes rest starting……….. thanx for view
