Haven't noticed safari issues, or settings. The App Store crashes a lot. Sorry to say the eiC app does too. Facebook (of coarse), and a few others. The whole experience is a bit slower. It hard to explain.
I haven't had any freezing, but my battery has been a lot worse. The standby time is noticeably shorter and it's annoying. I only use my iPad 2 for quick lookups while on the couch and it lasted me quite a while. Not it seems I'm down to 20% every 2-3 days.
My iPad 3 has not backed up since 10/11/2012. I have: reset; rebooted; excluded most apps from the backup (thinking maybe an app was hanging it up) & tried to manually force a backup; deleted the existing backup & tried to back up again; - nothing worked. Thinking maybe it was my Comcast gateway, I went to a different WiFi hot spot. This time it acted like it was successfuly executing the backup but after it "finished" it said the backup had not completed successfuly. Keep getting the periodic messages that it needs a backup but I can't get it to do it. My iPad sits right next to my iPhone 4, stays plugged in & is connected to the same WiFi network as my iPhone. My iPhone backs up to iCloud successfuly every day; my iPad has NOT backed up since 10/11/12. Any thoughts?
I just returned my iPad3 and bought the iPad4 Had to take one with a little more memory so it cost more money. But this salesman said it was worth moving to the iPad4. Now to start trying to understand it. Seems the thing shuts down pretty quick, I have to keep opening it up again. and again no manual on how to use it.
