Downloaded it just now.
Install went without issues on Android 4.2.1
getting two peers connected from the start, so that's good (95.85.2.86 & 192.241.151.155)
Exchange rates tab doesn't work (yet?)
The Camera icon is in a weird spot on the "home" page of the wallet (see screenshot)
Syncing doesn't seem to give any issues, however, the client isn't indicating how much syncing has been done, so it's hard to tell.....
Install space of the Quark app itself is 13,34 MB
Thank you for your feedback.
Connecting to two peers is normal. This app does not have the robust connectivity features of the desktop client yet. The bitcoin people will be adding that soon and when they do, I will import those changes into the Quark android wallet.
The camera icon appearing at the edge of the screen appears to be due to the sizes of the send and receive buttons. In english these buttons take up less room due to fewer letters to display on the buttons. I will try to see if there is a solution for this.
To see about syncing progress, go to options, then Network Monitor and scroll to Blocks if that part is not on the screen. If the last block is from 1 to 5 minutes ago, then the app is synced.
