Why does the backlight flicker after screen repair
I do between 4 and 5 iPhone 4 and 4s screen repairs each week and have been running in to the same issue over and over. Before I do a repair, I test the screen that I am going to use for the repair with a tester cable and old iPhone. The screens appear to be fine when I run the test, but after I install them on the customers' phone sometimes the back light flickers. I try to be very careful with the digitizer and lcd flex cables, and have even started pre-bending them on the dotted lines assuming that I must be damaging them during installation, but they are still flickering. Has anyone else run in to this problem?
Esta é uma boa pergunta?
