Thanks a lot for this tip. Indeed, I read about it, but never received this prompt on the phone. Have no idea why... Flash CC does recognize my phone, but there was no prompt. Could I have missed it? How to trigger it again?
Switching my phone active, unlocking it did not help. I will try to roll back to CS6.
P.S. From my colleagues I heard that Adobe stopped supporting Android versions after 3.0.0. Currently my phone has Android version 4.4.2. Could this be the reason of freezing when trying to publish on the device?
