I just noticed in my iPhone 6s Plus running IOS 9.1 that when I scroll inside apps like App store, Contacts ,Settings and Safari that this part of screen
start to show some kind of flickering specially when I scroll slowly inside these apps that stops when I stop scrolling & you should know that this problem happens when iPhone is either in portrait or in landscape modeband also that this problem goes away when I choose to reduce transparency in IOS settings & I guess that it is a software problem but unfortunately I don't have any other device to try right now so I just want to know does anyone notice this problem in his/her iPhone 6s Plus or it is just in my device ?
Thanks in advance
