If your T-Mobile iPhone has begun to freeze, crash and even show a static blue screen of death, don’t worry: you’re not alone.

Apple forums—along with Facebook, Twitter and Reddit—are abuzz with stories about iPhones that are running on the carrier’s network crashing. According to MacRumors, the problem seems to affect the iPhone 5S, iPhone 6 and iPhone 6 Plus devices running both iOS 8.1 and 8.3.

It’s not yet clear what the exact problem is, but speculation on Reddit suggests that a hard reset, turning off Wi-Fi calling and, failing all that, a full factory restore should help solve the problem. Good luck. [Mac Rumors via Engadget]
