I am led to believe this is a personal iPad issue, not an ipad 3 general issue. As I stated before, I have had two different iPad3s that have had zero problems and In fact function better than ever with the newest upgrade. Do you have enough free space on the device (they work optimally with about 15% free storage I have found)? Do you keep tabs open in safari? Like I stated earlier, have you done a hard reset yet? Have you gone through the settings and streamlined everything (iCloud, Bluetooth, privacy, etc) sometimes an update can change things you didn't realize.
If you still have this problem I would suggest setting up an appointment with Apple, go through the online support center to run a diagnostic test yourself at home if you want too. My first 3 was bought preorder and I still have AC on it for a few more days - so chances are you still have coverage too (if you purchased AC) so if there is a true problem that can not be fixed they should swap it out for you if you act fast.
Thanks for letting me know. Unfortunately, I don't have AC, so the warranty is way over. I agree though that iOS 7.1 is definitely better than iOS 7. 7 was just generally really slow and laggy and stutters too, but now in 7.1, the animations are faster and generally smoother, but this lag I'm talking about happens not every single time I scroll or something, but when I go back to home screen from using some apps for a long time. It seems like the app I was using is still being processed in the background when I go to the home screen. It stutters then after 2 seconds, the home screen is very smooth again. The stutter is not extremely noticeable if you press the home button (it's still annoying though), but if you do 5 finger pinch gesture to go to home screen, the apps coming together animation stutters a lot. Again, this problem does not happen all the time. It will happen time to time if you use it quite a lot. But as I mentioned iPad mini does not have this stutter at all, and it's completely smooth and fast.
I am wondering if some settings I have on are causing this. I have
iCloud on (contacts, reminders, safari, keychain, pictures, documents and data, find my iPad,
reduce motion off,
reduce transparency off,
passcode on,
multitasking gestures on,
side switch used for rotation lock,
VPN off,
background app refresh off,
spotlight only has Applications on,
Siri off,
voiceover off,
Darken colors on,
reduce whitepoint on,
switch control off,
assistive touch off,
Could someone maybe diagnose it for me? Or from those who really don't have any stutters I mentioned, is it possible for you to take some time and list out like I did above so that I can try to use the same settings and see if it solve the problem?
Thanks so much..
