Hello everyone!
I kindly ask for your advice regarding my situation with the touch screen issue on iPhone X and iOS 15.
I was using iPhone 7 updated to the iOS 15. Recently, I have decided to test out how does turn out FaceID in use and bought a used iPhone X with iOS 14 installed. Based on the previous owner's information, the iPhone on iOS 14 was working with no issues.
For successful restore backup from iCloud, I need to upgrade iPhone X to iOS 15 also.
Intermittently, when I want to unlock the iPhone, the touch randomly stops working. I have tried to bypass the lock screen with a double back tap but the touch issue persists. Hard reset sometimes does help, sometimes it doesn't and the touch is still not working. Nevertheless, after a while, the touch is working back again.
I experience this behavior usually in the evenings. I also noticed it has something to do with phone in the pocket affects this touch issue.
What have I tried so far:
• Full Reset & Erase (no restore from backup)
• Full Reset Reset & Erase via iTunes (no restore from backup)
• Update to iOS 15.0.2 + Reset & Erase via iTunes IPSW (no restore from backup)
• Update to iOS 15.1 beta 4 + Reset & Erase via iTunes IPSW (no restore from backup)
• Update to iOS 15.1 RC + Reset & Erase via iTunes IPSW (no restore from backup)
Unfortunately, the downgrade to iOS 14 is not possible anymore.
I understand it could be hardware or software-related. Should I wait on the iOS 15.1 release firstly or get the device inspected right away?
Thank you for your advice, any information would be helpful.
