[TIMOB-2941] Android: Galaxy Tab; Non repro crash - App UI locks up (back button non responsive though vibrate and sound associated with action fire) followed by the UI suddenly becoming responsive and app crashes. No reliable repro steps, but seen 4X today

I have seen this issue 4X today, and cannot reliably reproduce it. What happens is:
the test wil load, then when I hit the back button the UI becomes non responsive. The button will generate feedback 9audio and vibe), and then all of sudden the UI is responsive, the app goes back a level and crashes.

log:
