Q: iphone 6 crash

Try the following steps - if the situation is not resolved - you may need to bring it to Apple for further servicing

iOS: Not responding or does not turn on - Apple Support

If your iOS device restarts, displays the Apple logo, or powers off while you're using it

I Have simuler problem with ny 128 GB iPhone 6.

by Google it i found that tre problem is worldwide and Apple has NOT yet commented it.

IT schould be a flash controller that makes the bug AS i Can read... Took mine to repair at tthe store last weekend and They found no problems... The same Day i had it home again i installer all ny Apps  and it startes doing the same. The problem seems to be the flash controller when i google it, and it schould happen when you have alot of apps installed...... Guess thats why we buy a large phone......

took mine back to the store again today and i could force it to happen in the store so once again its sent to repair..... waiting to see what they want me to do about it.

I Have allways recommented apple for friends and people i meet.... But its really bad for apple that they dont come out with a conclusion and recall all the 128 gb phones, but lets us stand with the problem and have to send it in all the time...... Very bad apple.

Dealing with the same issue as of today and I'm furious. I use mine for work and am now stuck with no phone and was told the next available appt at the closest Apple store isnt until Wed. VERY dissa pointed in apple right now. They said they could over night me a new one yet I would have to pay shipping and it would take at least two days to process the request ??
