Yes I've noticed it also. In fact the new update is worse. Crahing, or quiting, or restarting much more frequently. I've noted the problems of crashes when people visit also (at least that seems to be a corrilation) which seems to me to be a row locking issue in the back end database or similar type issue. Not sure why the Sam bug wouldn't happen on iOS also, but it may be due to how the android app interfaces with the main server.
