There has been an ongoing touch issue with some of the iPhone X units as well as MacBook Pro 13 data loss problems and the company is now acknowledging them by launching a replacement program for both.
If you are one of those users experiencing “ghost touches” or the panel not responding to touches on your iPhone X, then you are eligible for a free replacement. You just have to contact your local service center and let them resolve the issue by replacing the panel or even the whole unit.
Along with the iPhone X replacement program, Apple is also running one for its MacBook Pro 13 units produced between June 2017 and June 2018. This one is for the data loss that some owners experience due to faulty SSDs.
