How can I get rid of this software update???

[StephenG1CMZ]

As you can see my Android now has a broken corner - which remains broken in HP Prime calculator. It's not just a screen display error, if I tap the face a screen pops up, rendering ESC and CAS keys difficult to use (although you can switch to portrait orientation to see which keys are obscured).

Hint: Facebook have recently decided to stop Android users from accessing Facebook messages unless they activate messenger... So I am guessing messenger thinks it is running on a dedicated faceBook toy, not a multipurpose device.

Perhaps I will get used to switching to portrait every time I want to hit ESC - But if not, how do I get rid of Messenger? Even if it does cripple Facebook

.    

For those users that like the permanent face, it might be worth thinking of changing the key layout on the Android emulator.

Update: The Android status shows "Chat heads active" - but with no obvious way of making the heads inactive. I haven't tried killing the task yet.
