iPhone 6 plus blue screen and reboot

No my moms 6 is doing it too, she's ATT, Im TMobile BUT here is something odd, turn off the wifi it seems to stop, I got away from the wifi at the store it stopped, I came home phone back on wifi it started again, and was going off and on more than ever, I managed to turn off the wifi it stopped. 😕 Where is Apple? whats going on??

I have an unlocked iPhone 6 plus using t-mobile. Been unstable for the past few weeks but today it really started being erratic. I backed it up and did a factory restore. Couldn't complete it because it started showing a blue screen then rebooting. I got it replaced at the Apple Store and now going through a restore. I'll report back if I still see the issue and will try disabling the wifi calling feature. No way am I deleting my iMesaage history.

Well, after hard reset and restore from backup, problem persists. Found it reset in my pocket.

Come on Apple, T-Mobile! Let's get it together.

T-Mobile pushed an update to me late last night. Turned on WiFi calling about 30 minutes ago and no issues. I will reply back if it does not work. So far so good.

@torp1464 What is the "Carrier" version number in Settings > General > About? I erased my phone and set it up from scratch, and I'm seeing 19.1. I'm also not seeing the problem anymore, but Wifi calling is OFF.

I'm on t-mobile carrier version 19.1. No problems on my replacement iPhone that has been completely restored from a Back up since these problems began. I do remember seeing something about a carrier update last night - but honestmy I was going through so many screens during set up and restore its hard to recall specifically. I did had a wifi call this morning with no problem, and wifi calling is turned on.

@odysseus I did the carrier update late last night or this morning and it is version 19.1.

Mine's fixed as well with 19.1 Carrier version but I didn't look at the version yesterday to compare. Needless to say, I got away with not having to factory restore my phone and not to delete all my messages. People should think before suggesting drastic measures like those.

The strangest thing about this phenomenon is that the crashing and rebooting started yesterday morning (June 24) for me, and I don't remember receiving a carrier update then. Does anyone else?

Mine just started crashing and rebooting today. What is going on her?

But, I'm in China,no wifi calling. It usualy hanpped bule scrren .oops😟

you probably bought it in the U.S. or EU perhaps originally on T-Mobile, is that right?

Yep i had the same blue screen issue 5 times with my iPhone 6.

Mine is doing the same thing constantly, it's an iPhone 6 16GB on Verizon. It has rebooted like 5 time in the last 10 min all on it's own.

Just had an interesting experience I wanted to share that might help out. I thought I solved my blue screen reboot problem on my iPhone 6 after I upgraded to iOS 8.4/ T-Mobile 20.0 last week. But then it came back this evening when I ran out of battery and started recharging. At that point, I got continuous reboots to blue screen. I tried hard resetting and then (immediately) rebooting, but it kept going back to rebooting. Ugh!

I then let the phone sit idle for several minutes after doing a hard reset (simultaneous pressing of power and home for 10 seconds). I powered up and my phone booted up just fine! The only explanation I can think of is that there is some sort of memory leak that clears after the phone is powered down for awhile. In any case, I'm ok for now.

Hope this helps.
