I have enabled spell check in English (US) and typing in same, but no red under-line in wrong spelling. It works fine in all other apps (not working here also in members app)

I'm facing issue in touch scree after July security patch. Keyboard becomes irresponsive, cant do fast typing as it doesn't take input and have to press screen little harder. Scrolling down also become slow.

Answering and ending call animation is very slow and laggy.While making the call:First: phone icon in notification bar appears.Second: screen turns into different colour according to the contact image.Third: name of the person moves from centre to up...

fingerprint recognition not working properly... need to fix this and also make it faster.
