T-Mobile iPhone owners have reported that their devices are flashing a blue screen before resetting.
Some users have reported that disabling Wi-Fi Calling can fix the so-called “blue screen of death,” while others have had to hard reset.
Some believe there is a problem with the phone’s memory, but that doesn’t sound viable because the problem is only affecting devices from T-Mobile.
Another possibility involves LTE. some users have fixed their phones, at least temporarily, by disabling VoLTE (voice over LTE) or shutting off LTE. This is perplexing, because VoLTE and LTE should not come into play when Wi-Fi Calling is enabled.
Affected iPhone models include the 5s, 6, and 6 Plus. The issue is also impacting multiple versions of iOS 8 through iOS 8.3.
