I've found a few bugs recently with my iPhone.
- When calling someone I cannot hear them on the phone, it will ring and then when they answer I can't hear them but they can hear me. Hard reset fixes this issue.
- When I close out of an app back to the homescreen, my phone will freeze for about 5-10 seconds.
- Snapchat still has this bug (video at the bottom)
Had one on my iPad a few days ago:
- Messages app crashed when I was sending pictures to my mate. When I went to open Messages it would crash after the initial crash. Tried hard reset and wouldn't open still. Had to reset all settings to get Messages to open again.
Both devices are on Developer Beta 3 (not the Public beta)
