Android stability on the XA2 seems much improved. Before, it was always a question whether an Android app could be reactivated once you've opened another app or simply swiped to the app switcher. I had to restart Android support very often.

Also, when stopping Android support, the display isn't turned off anymore.

WLAN in Android still seems a hit-and-miss. But since WLAN on my XA2 prevents the CPU from sleeping, causing battery drain, I've disabled WLAN anyway...

If only they could communicate this better.
