Process refer to our YouTube video about China Made iPhone LCD Screen Test. Another iPhone screen touch issue is the unresponsive screen or partly unresponsive screen. This problem is complex. New aftermarket screens unresponsive issues are seldom. Reasons for this problem may be the screen hardware or software. Most unresponsive screens are not repairable. Let’s talk about another serious touch problem of iPhone aftermarket screens, ghost touch. When we turn on the iPhone, the screen is jittering and keeps switching on interfaces. This is so-called ghost touch. Technically, this issue cannot be fixed because it relates to the problem of screen manufacture and software data compatibility. As we all know, most aftermarket iPhone screens from China are manufactured in factories of the mainland, while the touch IC, which is the core part of the screen, is supported by leading companies like Samsung or Taiwan Semiconductor. Most aftermarket iPhone screens made in China cannot meet the standard of this touch IC, that’s why the touch issue occurred. On the other hand, the iPhone aftermarket screen software is insufficient to computing the larger new iPhone drive IC software volume, that’s another reason why the screen has touch issues.

Finally, we should know the reasons why the iPhone aftermarket screens haves such touch issues so that we can avoid these problems. The simple flickering issue can be fixed by checking the flex cables and flex ribbon. As to the problem of the unresponsive screen, we should check new screen and contact to the supplier for after-sale service. Anyway, the QC to products is very important.
