[ONE Android Development] Timmmmaaahh!:
Hm, nevermind that. I may have set myself on a wrong track here. I couldn't find any "finsky" entries in my own logs but upon further research they appear to be present here as well (not as frequent though). Back to the drawing board.

This is a normal screenshot procedure:

An interesting difference is in the "device_name =". Mine has "speaker" while yours is showing "voice-rec-mic". Could it be that it is trying to address the microphone instead of the speaker to play the screenshot sound? That's just a wild guess. Let's hope some devs are tuning in because this is rising above my skill level :eek:
