Actually, I'm very pleased with the dinky Xperia Active:
- Although small-sized display of very good quality
- Super Form Factor
- Device seems to be very insensitive
- Speaker prima (no comparison with the tinny HTC Desire)
- Prima Ausstatttung
- Battery power I find OK
- Update policy of Sony, I find refreshingly good (Android 4.0 is announced for April)
BUT:
The screen flickers particular übelst in low light conditions. At first I thought that was a hardware problem, but my replacement device does not behave differently :-( Normally I would say goodbye to the device. However, since I almost think the other properties and I and the phone so primarily for sports not wants to use to surf or watch videos, I will keep it well and hope for a software solution. Perhaps it is the brightness sensor at some point away from it.
