Ran iOS7.1 beta on my i5:
Pro: Running iOS is much faster, such as animations, opening apps. Seems like the efficiency of RAM utility is better than former versions.
Cons:
1. The Videos Player cannot remember the position you paused last time if you close the App for a long time;
2. Text Tone is always Tri-tone whatever you set to another or not;
3. Sometimes the remote control of the earphone would occasionally break down. It can resume after restart;
4. Open the Camera at the lock screen >> Open the Camera Roll >> Slide up the control center >> Open the Calculator or Clock >> Respring definitely; (that bug also exists in iOS 7.0.4)
5. The Chrome App is not doing well and always crashes a few seconds after you open it;
6. Sometimes the screen would be frozen and you can do nothing but hard close.
P.S.: I am not sure if everybody here meet that bug in iOS 7.0.x official version, which is -
After you running the device for a long time, and many apps are staying in the multi-tasking background. Then you open the multi-tasking, slide the Apps to the last one, then press the Home button. It should be that all the Apps flicked and go back to the home screen. At last and the disgusting, the device would occasionally respring (Suddenly Apple logo and seconds later go to the lock screen).
Also, I have done a test and found about 102 different apps can simultaneously stay in the multi-tasking background. That means when you open the 103rd app, the first one would be kicked out of the background. But at that point, when you open the multi-tasking, there is much chance that the device will respring.
That BUG is annoying me very much. That is the only reason I don't like iOS 7 so far.
My guess is the respring is caused by overflow of the RAM. Fortunately, I didn't meet that annoying bug when I was using the iOS 7.1 beta. The efficiency of the RAM utility is allegedly improved on iOS 7.1, so I guess I will never meet with that bug when iOS 7.1 officially release, hopefully.
