Apple iPhone 5S

I have updated my iPhone 5S from 9.3iOS to 10.2iOS, so far so good, everything is smooth, battery is ok. however there are few things I noticed;

1. iMessage sending progress status is invisible, it only appears if sending takes time.

   
   




2. when I turn off the autorotate function, the assistive touch is hiding at the bottom of the screen when I flip the phone horizontally.

   
   




3. sometimes the assistive touch doesn’t response.

   
   




4. sometimes the battery percentage indicator jumps down 2-4% down instead of slowly 1% decremental.

   
   




5. sometimes the clock icon stops.

   
   




6. sometimes it is difficult to pickup signal compare to previous version.

   
   

.but, performance is improved a little.

.appearance is also ok
