I've been experiencing 2 annoying bugs after it automatically updated my ipad to the latest iOS.

1. The lock screen would stayed on forever and wouldn't go back to sleep after it's awaken by notification or alarms, I've to manually press the home button to turn the screen off.

2. Screen would randomly froze in black screen when it's not in used for a short period, but screen would wake after like more than 10 secs delay.

3. It's closely related to 2nd issue, after going into the home screen, when interacting with the screen for few secs, It'll then locked my screen out, and this bugs repeats everytime I unlocked my screen until I force restarted the device.

Jeez, could anyone please share your fixes if you have similar experiences as above..

I'm using Air 4, no home button..
