Dear Sir,

Do you meet any issue after replacing screen on iPhone X/XR/XS/XS Max with iOS 13.1.2?

We have tested TFT LCD, Incell, Hard OLED, NCC Soft OLED and Original material Soft OLED iPhone X screens on iOS 13.1.2, all of them work perfectly
Here is more details for your reference: 

In one word, please don't upgrade into iOS 13.1.2 now. Otherwise even replacing an Original new iPhone screen, these issues may also happen.
It's all about the iOS 13.1.2 bugs, nothing to do with screen quality. If did already, wait the new iOS, then upgrade into it.
