Ver. LT18i-2.8.31. Hello, first of all thank you for the awesome rom I've not had this problem before installing the last ROM. Issue appears randomly: when somebody calls, screen turns off immediately after pressing anywhere in screen or when I try unlock cellphone or turn off alarm. After it turned off I can't turn it on about 2-4 seconds (of course i try to press all the buttons that LT18i has ). Please help.
