On my android the camera is broken; is there any way to pair the device with my wallet without scanning the QR code?
Not at the moment sorry.
I'd like to try it on my HTC Desire, but I get an error on start up:
The app need android 2.3 or higher (currently set on google play to 2.2 which is wrong).
Balance shown in BlockChain.info Android app is different from that shown on web wallet, by 0.00813745.
Yes this is a known bug. The balance on the iPhone/Android shows Active and archived addresses. The balance on the web wallet shows only active addresses. Edit: Sorry read the whole post, seems like a different issue - I've noted it down.
Off to the States on the 26th, will probably not have time to fix any of these bugs until I get back on the 1st.
