An iPhone 12 Pro Max touchscreen can become unresponsive for several reasons. For example,
a brief hiccup in iOS could render it unresponsive. While this is often the simplest cause of unres-
ponsiveness, other factors like moisture, debris and APP glitches can all have an effect.

In the absence of these issues, there’s a possibility the screen could be damaged because of an
accident. This situation may call for repairs or replacements. That said, you need to spend a for-
tune to buy a new LCD screen for your iPhone 12 pro max.

Recore finds a new way to solve - that is replace an external touch screen with front glass.
Pay attention: External touch screen not only fixes the touch function,
But also solves the problem of pop-up windows,
What's more, restored the one-key wake-up function.
