Doesn't work on Acer A500 tablet Doesn't work on my A500, no matter which way the hardware orientation lock is set. This is the first and only rotation app I have installed so far, so no conflicts.
I take it back It doesn't work.
Doesn't stick Works for a bit, then reverts back to default. (Nexus 4, Android 4.4.4.)
No reverse portrait.
Good Now i can make my viber always potrait.
LOVE IT It works fine with me
