Breaks keyboards I reported this bug 2 months or so ago and no one responded to the bug report. Ac display interferes with keyboards  and it is replicated easily. When the device is put to sleep or the screen times out while in an active text box (tested mainly with hangouts  but it happened while typing this review)  the keyboard will not input text when you wake the device up. You have to back out of the message for it to work again. This was tested on a nexus 6  multiple roms  Google kb and SwiftKey
