https://commons.wikimedia.org/wiki/Category:Uploaded_with_Mobile/Android just crossed 1,000 uploads. The deletion percentage is still low (~10%, and I think that is over-reported because of initial test uploads).
Yay! Looking forward to more uploads :)
P.S. You can get the latest released app from the play store at: https://play.google.com/store/apps/details?id=org.wikimedia.commons
