The iOS 12 GM was finally released after yesterday event. All the enhancements of the official version improve performance on all supported devices, going all the way back to iPhone 5s and iPad Air.

It’s definitely a great news for iPhone users, but for aftermarket industry, the update could be quite unpredictable based partly on the experience of previous years. So, once the iOS  12 GM was released, we made a performance and compatibility test on aftermarket iPhone LCD screens including different brands of CMRs and HO3.

*Notes: In this blog, we take iPhone 7 Plus as the demo model.
