Well holy balls, I thought it was just me.

My 5c (!) has been doing this for the last day I figure.

I haven't seen a blue screen per say, but a lot of fades to red and green.

I bit the bullet and did a hard restart and that seems to have fixed everything. The last time I did a hard restart, I was in an endless boot loop and had to jump through hoops to reupdate to the beta and restore my phone.
 
I actually experienced this today at lunch. A blue screen (it happened kind of fast but I seem to remember two tones of blue, one a little lighter or darker near the area where the bottom dock is) and then a hard restart. I've had some memory issues with my iPhone 6+ in the past (I had to have one returned), but the restarts I get from those are always soft resprings. This one was a full, reenter-your-password restart. I think it may have happened twice. Very strange (and yes I'm on T-Mobile).
 
This is obviously related to T-Mobile doing something. For the people having a problem: Did you recently click "okay" to accept a carrier update? Also, what is your carrier information listed under Settings->General->About? (Mine says T-Mobile 19.1, but I''m not having any problems).
I haven't updated my settings recently, but i'm on 19.6.
 
Yeah, it's not memory cause I have 40gb available and suffered 5 BSOD crashes today as well. Unless they mean RAM...looks like T-mobile is version 19.1 and probable sum disgruntled employee that planned on leaving decided to paint his "Developer's Mona Lisa" by letting a timed kernel panic causing memory freeze give T-Mobile customers crash issues preceded by the signature Windows BSOD. I also witnessed that blue flash...Anyway, just fix it T-Mobile ! 19.2 !

RAM is what "memory" is.

Your 40GB available is "storage."

Nothing for the past half hour, thank goodness.

This actually happened to me twice this morning. I didn't realize it was a "thing" (until now); and it hasn't happened again today.

To those who say it hasn't happened to you - I would likely not have noticed the first reboot if I hadn't attempted to unlock my phone with TouchID when I got up this AM. Since it had apparently rebooted overnight I was required to enter my security code - I saw the springboard, then a blue screen followed by a new reboot.

Addendum: iPhone 6 Plus (64GB), iOS 8.3 (12F70), T-Mobile 19.1

can't take credit for this, someone on reddit may have found the solution:

He said to go to settings - phone - and switch off wi-fi calling. This seemed to have fixed it for those I know who were affected. Apparently you only have to switch it off, wait a few minutes and re-enable it, but those affected haven't switched it back on.

Hope that helps!
 
It isn't limited to T-Mobile. I have AT&T and this happened to me this past Sunday. Apple Genius bar gave me a new phone.
 
My iPhone 6 Plus (on At&T) has been restarting randomly for at least 3 weeks now. Many other people I know (not just T-Mobile) are experiencing the same thing. I toggled off/on cellular data as I have read online elsewhere but it only seems to help for a day or so. It also seems (in my case) that if I have more than 4 apps open it will almost always restart.
 
Its not only Apple Iphones . My brother has been complaining that his Samsung S5 is doing it to. so its definitely the t-mobile carrier
 
IMO, the best work around would be to force the phone into 100% LTE and ignore 4G signals for now, but I dont think that is possible.

At work, I get 5 bars 4G and 1 bar LTE...guess what the phone chooses to connect on...
 
Wow. Just came to MacRumors to see if anyone else was having this problem.

iphone 5s on Tmobile. It seems to keep restarting when using Twitter and Mailbox. Haven't tried any other apps since it keeps restarting.

I'll read through this thread and see if there are any fixes.
 
This would be me - sitting in Panera tonight about 5pm, on wifi, it did it. I didn't even have signal in the building - hence being on wifi. Like, it was searching for the signal - nothing. On reboot i had some edge, then it jumped on the wifi.

I was totally surprised to have it happen - I hadn't had it happen the rest of the day. Last weekend at Disney my battery was sucking dead before my eyes. Turned it off, back on, killed all apps.... went from 16% to 2 in 45 minutes. Ok then.

64gb iPhone 6, tmobile
ETA: I was using safari, with a mobile friend website that worked fine after it did it

A hard restart has currently allowed my phone to stay on for over 40 minutes.
 
If that doesn't work, T-Mobile is instructing customers to clear out their old text messages and do a factory restore via iTunes.

It still sucks that for most issues, a "factory restore" is the advice, losing all app data.
There needs to be a restore method that preserve app data, but renews all the iOS files killing off any issues, because the issues won't be caused by whatever is contained within an app's documents and data.
The answer to that shouldn't be "well Apps should store their documents and data on iCloud".
 
Happened to me this afternoon. Just once, though. I am on T-mobile with an up-to-date iPhone 6.
