[Android client] Pass button confirmation and other question

[Phelan]

I've had the android client for a while, and I've pressed the pass button a few times while moving my phone around. One of my opponents was gracious and accepted an undo, but others did not. Would it complicate things to add a confirmation for a pass too?

Also, whenever I try to place a stone in one of the lower coordinates of the board(close to the UI), I sometimes get an avatar popup, as if I've clicked on the avatar. Don't know if I might be the one doing something wrong there, but it's happened pretty frequently.
