This has happened to me.... a lot.
First, a few questions, then I'll give you the long fabled history of my issue.
1: Are those of you who are having this problem using Gmail? And are you using it in the Mail app and/or via Safari?
2: are you on your first iPhones? Or have you owned previous models?
3: which iPHone do you have and what size? (32gb, 64gb?)
I've had a 3G and a 4, and I'm now on the 4S 64GB. Before the 4S I never had a problem.
Problems since buying the 4S:
- my 4s crashed a lot when not in use. I would return to it after leaving it in standby for a while (ie: I finish a phone call, I turn the screen off and leave it alone.) Upon returning to the phone I find that it's off and needs a hard reset in order to start it again.
note that the crashing has become a lot less frequent with each attempted solution, and could theoretically be unrelated.
- Safaris Cookies keep changing to 'never'. An important fact here: this isn't "reverting" to never. The default setting is to accept from visited. So the change is extra strange for this reason.
- Maps: while I set it to "show traffic", it keeps changing to hide traffic.
note that the cookies and traffic issues happen at irregular intervals. And so far as I've noticed, they don't seem to occur in unison.
- My email settings changed to 'sync only 2 days' as opposed to just showing everything. This happened once only. Points to note: I have 4 email accounts associated with my mail app, and two of them are gmail accounts. This ONLY happened to the gmail accounts. At the time, the Gmail accounts were setup via Exchange (google's free exchange/push service).
Attempted solutions:
- Restored the phone. Problems kept happening.
- Was given a replacement phone. Problems kept happening.
- Restored the replacement phone, and setup as new device. Problem kept happening.
- Took off the Exchange accounts, at apple's suggestion. Problem appeared to have gone away.... for two days. Then they started again.
- Replaced the phone a second time because the guy at the Apple store couldn't think of anything to say except "this isn't my fault, but why we'll give you a new phone if it will make you happy" (-- repeating this s though I were being confrontational. Boy must he have been having a bad day.)
As the phone(s) has been restored as new twice, after which I never got to the point of reloading all my apps, music etc., and because things such as using an exchange server have changed, and the phone has been changed twice, here are the only consistencies I'm aware of:
- I have 2 google email accounts in the mail app
- I access a 3rd gmail account via safari
- I use iCloud for calendars, contacts, reminders, bookmarks docs & data and find my iphone
- my SIM card is the same (can't fathom why this could matter.... could it???)
- my iTunes account is the same.
As of now, I've restored this 3rd iPhone 4S 64GB and set it up as a new device. I did this an hour ago. I'm making a point not to load any apps on here at all. No exchange accounts at all. And I'm going to see what happens.
