Joying JY-UMS03N2 volume - Android Head-Units

I have a rooted unit, and i bought a usb remote control. When i use it to lower the volume, the joying will turn the volume back up on its own. Is there a way to fix this? Please help. Its frustrating with the side buttons on the tab.

Xtrons Weird Volume Control

Not sure if this is the correct place to post...
Fitted a Xtrons Android Headunit last night. Very pleased with it so far. Still making tweaks to the sound do get a little more power and bass. Google maps works a treat on it.
However... currently the volume button on the steering wheels changes the volume but also cycles through apps, is there any fix for this?

I want to change the volume knob click function to the home button. And get Amazon music to work with the front skip button controls since they currently only work with the radio and music app.also af ew other things like nav volume ratio to music when it plays over it. for some reason this head unit settings is very limited.

Unknown Joying HU volume question

Hello from Belgium!
A week ago I bought a VW Scirocco 2009 (without SWCs). This car had an unknown Joying HU (running Android 6.0.1) installed, also without any button controls.
I'm fine with all-touch displays. Only thing that bothers me is the volume controls needing precision aiming and focus when driving.
I installed AGAMAcar launcher to try and solve the issue with the gesture based volume control + BIG volume buttons. But alas, the volume goes down, but immediatly goes up again.
Is this connected to the factory settings of the HU? What should I change?
Note: I am not well-versed in HU and audio talk... So sorry if I'm asking something way stupid
After looking on the forum for some answers I came up with all unsolved(? - as far as I could find) threads about similar issues with volume control.

Problem with volume on Joying 13” Head Unit

Hey guys!
I’ve been searching a ton for an answer on this… but can’t seem to find anything. I installed my Joying 13” head unit and wired up front speakers (will do my rears another weekend). The head unit is great, except that the volume is stuck at a high setting. I use the volume up/down buttons and the volume slider changes and the numbers go up and down, but the actual volume doesn’t change. It’s like the software isn’t talking to the hardware…
Any suggestions? I’m thinking of updating firmware in case that might work… but out of the box I would think the volume would work.
Thanks all!
@opexo any ideas
