I have the same problem with my iPhone 4S & iPad2 running iOS 7.1. Been driving me nuts. It's happens for sure on Safari, FaceBook, General Settings, and many more. It's maddening and I've lost tons of hours of work, productivity, progress, it never fails I've got an hour worth of focused work done, I'll get a call, text, or email, and when I return to the app it refreshes and loses everything I was doing. It's the same on the iPad2. This combined with the constant app & iOS crashes & freezes, battery drain worse than ever, glitchy operations, display freezing up every 5-6 words being typed for several seconds, display anomalies, lock ups when transitioning between cam & photo albums, endless rebooting when trying to shut down, and this extremely annoying sound issue that started after updating to iOS 7.1, where all kinds of sound issues are happening:
-phone ringer works, but no notification sounds & iPod music is playing but no sounds.
-the opposite: phone ringer doesn't ring, but notifications do & you can hear iPod music.
-sometimes is stuck in an entirely silenced mode. Nothing makes a sound.
-IPhone side silence switch is on the opposite status as is displayed in Assistive Touch. They don't line up.
I have tried resetting all settings & 10-20 other so called solutions, but none of them have worked for more than a few minutes, before the problem comes back again.
I've been on the iPhone since the very first one. And have 2 iPhones & 2 iPads. They are all unusable & crap to work with. Been pulling my hair out for weeks. This is ridiculous & subpar for any phone or consumer device. The Apple devices have become useless.
And I haven't even got into all the bugs in iTunes & iCloud. Or ones present before the upgrade to iOS 7. I'm ready to throw all the apple gear in the trash & go with the latest Galaxy.
Have Apple addressed or fixed any of this stuff?
