Q: iPhone freeze while taping emails.
Hi,
We are a company, using iPhone 5, 6, 6+ ; we have installed MobileIron on each device, and we are using an exchange 2007 server.
Problem is :
A few users are complaining about the iPhone because it is freezing many times while they are taping an email. This problem is not really new, we had this problem using iOS 9.0 then 9.1, 9.2 (and now 9.21).
What's happening ?
User is replying to an email, everything is ok, and suddently the loading icon appears (near the wifi icon, on top screen) , and he cannot do anything else.
* If user wait (30-60seconds) then he can continue.
* If user press the Home button, then at the end of the freeze, all apps are sent to the background, and if he reopen Mails, the current mail (he was writting) is lost & not in the Draft folder.
When I have reconfigured the iPhone, I have :
- Use the "Reset All Settings" function.
- Activated the Apple account as a new account (no restore from previous backup).
- Deactivated all iCloud function.
- Deactivated predictive text.
- Deactivated App background refresh.
- Deactivated WIFI Assist.
- Sync emails for 2 weeks.
- He is using Word / Excel / Powerpoint, no other additionnal app. I have installed those apps on my device and for the moment, no problem reported from MY side.
We also tried the same thing with an iPhone 6 S Plus 64Gb, same problem.
Any similar issue ? Or tips ? I have no other idea....
Thanks for reading !
iPhone 6 Plus, iOS 9.2.1
