One of my friends has Q3. It had some issues with bitstreaming. For example hd audio always stereo with kodi. (Still is) Atmos mixes and some videos with aac audio always silent. On internal player (not kodi) bitsteaming works but videos with aac and atmos audio always silent. And after some app installed from google play wrapper stops for no reason. With internal player blank (black screen) video but audio played and subtitles shown. Fix was only factory reset.
After a update those issues are gone but this update was an android update not a firmware update. Of course we updated firmware also. Now it working fine.
