The Financial Times today highlights an issue purportedly plaguing a growing number of iPhone X users.

The report cites a growing number of complaints on Apple’s support forums.

The Financial Times reached out to Apple about the issue and the company reportedly stated it is “looking into these reports” but didn’t offer any insight as to what was causing the problem or when it might be fixed.
