I picked up a 256gb XS last Saturday and have been having a few issue. On odd occasions inbuilt apps (settings, notes etc) froze and I have to go back to the home screen, close the app down and then open it again and it will start working again. Also, animojis would not play properly and would just quickly stutter back and forth whilst a 'play' icon would flash over the top of the Animoji, this happened for both sent and received animojis. I tried soft reset but this didn't help so yesterday I did a full restore which seemed to work until this morning when the settings app froze again. Animojis still seem to be displaying properly though at the mo. Also I noticed that my battery had drained 70% overnight. Have other people had similar issues and is there a known fix, or is a case of going back to apple for a replacement?
