Hi all!!!!
Ok first, PLEASE lets calm down a little....... (meaning lets not think it is hardware related until you follow the steps below PLEASE)
Ok now that we are calm, lets take this in baby steps PLEASE.
Lets understand something related to ALL computer devices.
1. When we get our devices (computers, mini computers, that is what they really are), we load programs / apps in this case, and an app is only as good as a developer writes/programs it. SO we get good, great, fair, and finally JUNK apps that put junk on our computers / SMART PHONES (mini computers).
2. How do we get rid of or even find the junk and fair apps.... NOW that is the best question.
A. Try to find apps that freeze a lot.
B. Try to find apps that don't open.
C. Try to find apps that are not updated enough or at all.
D. Try to find apps that are no longer in the app store (this was my culprit most likely)
E. If A, B, C and D are taking us too long or not possible to find then use option F.
F. Format the computer and start from scratch or in this case Wipe the phone completely and activate as a new iPhone.
3. Sometimes programs and apps can find others that are causing or caused issues and those programs or apps can fix the issues (like restoring from a backup in our case's) BUT other times NOTHING will work but a format (wipe and set up as a new iPhone).
4. If after you have tried
A. wipe and restore
B. wipe and set up as a new iPhone
C. LOADED very little apps (after you did B) for a few days to make sure one of your favorite apps is not causing the issue (due to it not being happy with the OS or the developer screwed up, they are human).
and neither has fixed your issue THEN YOUR device is most likely defective.
Now the Wipe and start as a new iPhone worked for me, I have not seen one reboot yet and I am going on a week (this weekend), Now I also did not load any apps that are not available in the app store, AND I was picky as to load apps that have not been updated for 2-5 years, on those apps I looked at the reviews and if others had negative about the app not performing and not getting updated then I did not load it.
Do you have an old local backup that you can use?
The OTA updates will reload everything from the app store, whereas restoring from a local backup will reload whatever version (and game data and settings) was locally backed up using iTunes.
I have loaded from my backups many times before I posted here (I do not back up to the cloud, only to my computer) So yes, maybe if I did the cloud, a restore then would have MAYBE worked, but a good flush is good for computers and mini computers (smart phones) from time to time, especially going to a new major OS update like IOS8.
My androids would also need a flush after a major update or they hiccupped and chugged also, I know IOS is better BUT IF we encounter these hiccups we need to follow these instructions.
I hope this info is helpful, Thank you for your time and PATIENCE.
EDIT: Please learn from my stubbornness, by not starting from scratch until after a phone replacement, that did NOTHING for me.
