About the "black screen" issue you reported in -dev3:
Can you please update to this one
And if you see this "black screen" again
Please wait for "Application not responding" window (5-15 seconds).
Then kill the app.
Then run the app, enable settings -> debug -> debug log
Start a new message, and choose "Diag: Attach logs" and send this to me.

Since this version, "attach logs" also attaches the Android system level "application not responding" log (called traces.txt).
And this should have the info I need.
