I have a Huawei P8 Lite (Stock ROM 5.0 Carrier: Telcel). I've seen a weird and annoying behavior which may be related : * Keyboard hides on its own while typing or not (Super annoying!) * Youtube videos just pause out of nowhere.. It happens every 5 or 10 seconds. * When I hit the app switcher button and get a preview of all the apps that are running it closes sometimes. * When I'm adding a new calendar event the add menu closes and the task is saved. I know for a fact I'm not accidentaly hitting the back button (My hand is nowhere near it and the button doesn't light up). I have no screen protector. It happens with any keyboard: Huawei, Google, Swiftkey.
