I'm using 6+ 128GB. I've tried from iOS 8, 8.0.2 to the latest iOS 8.1

However no one update can solve that crashing problem.

I've more than 1000 apps installed since I'm using every generation iPhones since 3GS. I prefer to keep all the data including app. That's why I have a lot of apps in my iPhone (background opening app only those regular use apps, NOT open many apps and all keep running in background)

I have NO problem in the past, even iPhone 5s after upgrading to iOS 8 also no crashing issue with so many apps restore from backup.

But, the crashing issue is started since first day of using iPhone 6+ . At first I thought iOS 8 maybe not yet optimize for 6+ and I hope that iOS 8.1 will solve it as the crashing is really torturing. It just crash randomly and frequently. Called Apple technical support as the issue remain after update to iOS 8.1 but the staff feel very strange on that issue and unable to help. I tried reset all settings, restore iOS then restore in iTunes, tried many times of different troubleshooting also failed. Crashing remain.

As some data really important for me so I can't totally set up as new phone. I need at least have the important data keep in the phone. So I started to try delete not important apps and its data. Now I left less than 200 apps. Restarted the phone and surprisingly it solve the crashing issue! No more crash after I delete those apps.

Actually not only crashing issue, the iPhone 6+ got 4 major issues I face:
1. Crash randomly. Restart randomly and frequently.
2. Unable to change wallpaper. After set new wallpaper, it remain the same wallpaper.
3. Home button + power button cannot screen shot
4. Home screen icon will not rotate follie the direction I hold 6+ (portrait orientation in UNLOCK mode)

Now all that 4 issues above solved by just delete apps. I'm not sure the issue appear with how many apps are installed. I guess this is an unnoticeable bug (as not much ppl actually keep too many apps), still I hope Apple hear our voice and look into the issue and fix it.

Btw, from what I read thru online forum, it's seems only happen on 6+ 128gb model only. Anyone 6+ 128gb owner here encounter the same issue?

I just used to keep things... Haha. I will delete if there's no space available on my phone.
Ya I don't really use most of the apps. But I never face such issue of having "too many apps" and cause the iOS problem. This is the first time and only happen on my 6+. So this should be one of the iOS bug? And not many ppl will have this issue as not many ppl keep so many apps on their phone.

It really works great now after I deleted most of the apps. Now I only have less than 200 apps and all the 4 major issues I mentioned already solved.

So for those who are having this crashing problem, maybe u can check if u have too many apps installed? If yes, than just delete those unuse apps as many as possible. Then it should solve the issue.
