I think it has something to do with testnet3.
Yes, testnet2 has become quite rough during the last months, AFAIK mainly due to the mining rules change. How is the prodnet version doing on your phone?
testnet3 is not (yet) supported by Bitcoin Wallet, and I'm thinking about what a good transition would be. Certainly I do not want to maintain three flavors of the same app.
I just downloaded and installed the prodnet version and it crashed at startup =) Two reports sent. But now it's currently downloading the blockchain and I'm gonna test more tomorrow.
Btw, I translated the app to swedish at transifex to 100%. so I hope we get it in the next version.
One thing I noticed is that on the main window when I scroll from Both to ether received or sent the background gets gray if it don't have any transactions. I got that bug running Android 2.3.7, rom CM7.2 on my phone.... I don't have that on android 4.0.3 on my tablet.
