I will try to list everything that has happened in order. Bought iPad Air from the Apple Store on December 30. I only wanted it to read my existing digital comic books and maybe some books. The device had 7.0.6 already installed. Downloaded Comic Zeal from the App Store for about $4. Sideloaded comic books via iTunes. The device began to crash about 2 weeks later, intermittently, then more regularly over the following couple of months. It also began to crash in native applications, and sometimes even when simply turning on the device. It would crash to a black screen, the home screen, the lock screen, and once it turned completely off. I had to use Home+Power to turn it back on again (totally reboot). I called Apple twice during this period. They walked me through a complete re-install. By then, as I recall, 7.1 had already been released. I installed 7.1 via iTunes and set the device up as a new iPad Air, from the device itself. This time, I downloaded Comic Glass from the App Store on the iPad Air. It began to crash within a day or two, and also crashed in native applications. Just two weeks or so ago, Apple Care sent me a box to ship it back to them, and said they would send a replacement. The replacement came from China and the whole process took 10 days. IPad Air #2 arrived with 7.1 already installed. I set up the device without iTunes. Re-installed Comic Glass and side loaded comics via iTunes. The device started crashing almost immediately. Not as often as at the end of the prior device's tenure, but often enough. Apple Care advised me to Reset from Settings on the device and download from my App Store account, rather than using iTunes. I downloaded Comic Glass and this time did not side-load any comics. I also downloaded iBooks. In Comic Glass, I downloaded some free comics from their samples archive. They were all in Chinese and unreadable by me, so I merely flipped through them. All seemed fine. In iBooks, I found lots of free comics to test, and books as well. Ibooks began to crash fairly immediately. In addition, Safari was crashing quite often - even more than in the reader apps. It crashed in Comic Glass, and in some of the other native apps - Notes, Reminders, etc. By this time, the device was crashing even when I wasn't in an app. Sometimes when simply turning it on. I then did a complete Erase via Settings on the device. Repeated the set up without iTunes. Bypassed iTunes altogether. Downloaded only iBooks from the App Store. Downloaded only one comic that I had previously downloaded in iBooks, using the app on the device. Experienced the same crashing, in this app and the native apps. I am about to ship this second device back to Apple. I have insisted that they REPAIR it, to really diagnose it, rather than merely shipping me another one from China. I'm quite confident there are quality control issues with the brand new devices, and I would like a more meticulous examination. My question, at last, is this: does anyone have any definitive ideas about what is causing these crashes? It is clearly not the apps - I've used far too many on both devices. They can't all be bad. Crashing is happening in both OS incarnations. It has happened on two different devices. I do not want to be stuck in an endless loop of returning non-working iPad Airs. The Apple Care rep had the gall to tell me she "just doesn't see this sort of problem." A quick Google search will show that this is happening A LOT. There are dozens of posts both at Apple Forums and MacRumours. Here's an article: http://www.digitaltrends.com/mobile/ipad-air-problems/ By the way, my iPhone 4S, running 7.1, is not crashing at all, in ANY apps. It's definitely the Air. Finally, I'm an Apple Girl - for decades now. I want to love my iPad Air - I truly do. But this is wearing down my capacity for loyalty. I want Steve back. Didn't they manage to get his DNA for future cloning? Thanks for any non-trollish responses.
