China makes iPhone LCD won't work on new IOS 9.?

Hi guys,

Recently, I replaced some LCDs for our customers,I recognized that the rate customers came back to our store and complained about their Iphone keep restarting again and again. Even with customers changed their LCD very long ago, the phones acted the same way. The machines keep rebooting and some stuck on Apple logo. I have switched several vendors, but it still acted on that way. But when I put on OEM screen or OEM refurbished, it works like normally. I heard that Chinese LCDs won't work on new IOS 9.xx, I don't know if this is correct. If anyone here have the same problem. Please let us know.

Thank you very much!
