Since the update, I've noticed that it is particularly difficult to scroll a cursor to the edge of the screen.
Often, tapping on an icon or a function button near to the edge of the screen causes the window to close and go back to home screen.
This happens a lot for instance in WhatsApp when sending a message.
Frequently, now, after having composed the message, hitting the green send arrow closes the window as normal as when the message has been sent, however the message has not been sent.
It seems that now tapping close to the edge of the screen causes the window to close and revert to home screen. This is happening in multiple applications not just WhatsApp, and it's only started happening since the update to UI7.
Please revert this or find a fix.
