My iPhone 6 is randomly restarting, I lost all contacts and photos

my daughter's iPhone 6 is having all the same problems as yours. Her iPhone is deleting her messages, shutting down unexpectedly and saying all space is used when most of her photos deleted. Did you get any help from Apple for this problem? Can you help us, do you have any suggestions? She is losing all of her messages unexpectedly and many are work related and important contacts. Thank you

Customer support actually told me I should try to delete snapchat if any steps you find online doesn't work.
Which I did, now my phone won't even start or reset.
The most I get to see is the apple logo or a loading screen.

Oh and they told me I lost my warranty like the day before I called them.
Can't even use that ****** watch since it pretty much doesn't do anything without an iphone.

I'm having the same problem. What I do is:

Go onto the Photos app.

Press on 'Shared'.

Create a folder with no photos in it and send to someone (they don't receive it).

Go onto the Internet.

Search something.

Check your photos.

They should be restoring.

If this doesn't work, go to your nearest Apple Store.

Mine has been shutting down apps like chrome and I'm losing all websites I saved and I have to resign in apps and websites. Tonight I changed the contact "me " picture and I lost all my contacts. I did a hard reset and only SOME of my contacts came back. How do I get all of them back??

Did anyone ever get a response or solution to this problem?? My iPhone 6s Plus has done this about 13 times in the past month. Messages and contacts are deleted, and now photos are as well. Ridiculous!

Having the same issue. It deleted my photos. About a month ago it crashed and deleted all text messages and completely reset my phone as if it was a new phone. I deleted my music which was 1.6 gig cause there was no more room. And now my photos are gone. I haven't added any new apps and as a matter of fact I've deleted a couple more and my phone still shows no or very little capacity. I was using google maps the other day and it kept shutting off and asking for my password did it five times with in a 10 minute period. When I hook it up to my computer to update it says it has the latest update, and it's not the latest one. My phone will not update at all. I'm at 10.2. Also from the first crash it won't hold my tabs on safari. It's a mess to say the least.

My iPhone 6s has started to do the same thing, Ive also got very little storage so am constantly deleting apps and pictures. My phone restarted itself while I was using it the first time and when it came back on my all of my 2,000 photos had disappeared apart from 40. Since, 100 have synced back from iCloud I assume. I have a mac and all of my photos are still on there on iCloud just not on my phone :( I've tried syncing it and it hasn't worked. Anyway I wasn't too bothered by this because the photos are on my mac. But just now I was on my phone using iMessage and it's been bugging recently- one message received will keep coming down to where new ones would be and giving me notifications for that message. I tried just refreshing the messages app (by double tapping the home button and swiping it up) and then when I re-opened it all the contact names were still there with the last message sent but all previous messages had disappeard. Then stupidly refreshed it again and all of my messages logs just disappeard all together :(( this is upsetting as there were important and sentimental messages and photos on there :(

I ended up going to the Apple Store and having them wiping and reinstalling the software. Said there was a glitch. First issue I've ever had with one. So backup to the cloud on what you have. My photos came back.

I had something similar of the sort happen to me and I lost a certain message thread by accident. (This is going to sound extremely risky but I did it and it worked) I was told by Apple Support to go into Settings> General> Erase all content and settings and press "yes" 2 times.

Then wait for your phone to restart and when the ICloud backup screen comes up after the "hello" and setting up everything for your iPhone again, make sure you select the backup that you remember having those pictures and contacts and it should restore everything back on to your phone.

This happens to me all of the time! I've tried updating to see if it works, but it just brought me to a black screened phone that would not turn on for 2 hours. I thought it was something I was going, but apparently not. This *****.

My iPod has been doing the same and I have tried everything. Even tried getting my pictures back but I couldn't because I haven't backed up since an year and neither have synced to itunes. My iPod doesn't turn on at all anymore, just shows the apple logo and I don't know what to do. My iPod has pictures I don't want to lose, is there any way at all to fix this problem without losing the data?

Also in my settings my phone seems to think that the photos and messages are still there? (Not many photos as they're on iCloud)

1) You said that there are no pictures on your phone anymore but try connecting your phone to your computer anyway just to see if they import or show up on File Explorer (on a PC) by any chance, little to lose at this point. If the pictures do not show up on your computer (which is likely), then,

2) try going to iCloud.com and see if they are there. If not they may well be gone.

IMO your phone is either badly corrupted or the hardware is on the blink. A restore would determine if it is system corruption. Otherwise you would have to take it to an Apple Store for hardware evaluation.
