Guys, did you mention the phone has a noticeable lag when trying to go on the home screen by pushing home button ? For example - I am reading emails , mail app is open, and when pushing home button it freezes and does nothing. Pushing again it shows me the open apps. And just after pushing third time the home button it closes the mail and shows the home screen. It was the same with original 9.0 and with updates - 9.0.1 and 9.1pb3. The phone is set as new with no apps installed yet.
