Apple iPhone 6 Plus - Gold-4

iPhone users on T-Mobile are experiencing a mysterious problem that is causing their handset to reboot randomly after 10 to 30 minutes of use. Before the crash, which affects a number of different models, the device displays a "blue screen of death."

MacRumors reports that the issue has been seen on the iPhone 5s, iPhone 6, and iPhone 6 Plus — and users have been reporting it on forums and social media, including Facebook, Twitter, and Reddit.

"So this morning my iPhone 6 (4 months old) started just randomly restarting itself every 20-30 minutes or so," writes one iPhone owner. "I wasn't even using it most of the time, it was in my pocket at work (could tell because of lock screen that indicated I needed to enter my pin after a restart as opposed to finger ID)."

Not only is the issue affecting multiple iPhone models, but a number of different iOS versions as well — including iOS 8.1 and iOS 8.3. It's not totally clear what has caused it, but some suggest it could be a buggy carrier update that T-Mobile has quietly pushed out to its customers.

One user, who spoke to T-Mobile support about the issue, says the carrier believes it to be a memory problem — and they have been receiving a lot of calls about it from disgruntled iPhone owners.

T-Mobile has been instructing users to perform a hard reset — by holding the power and home buttons for a few seconds — to try to prevent the restarts from happening. But if that doesn't work, it recommends performing a full factory restore via iTunes.

Hopefully, T-Mobile or Apple will be able to address this problem very quickly.
