iPhone Touch IC Swap or Not?

While several aftermarket touch panels may claim not to cause the "Important Display Message", these all failed to stop the message after iOS 15. Any new versions that may work at the moment could potentially fail to stop the message at a future iOS release. High quality replacement touch panels will always cause this message.

We recommend swapping the IC from the original screen, not just to avoid the message, but we find the touch calibration is the main reason for this change. It will avoid warranty replacements for your customers due to bad touch response.
