[Android Head-Units] CCJ22:
Creating this thread for owners of the newly released 2023 Joying head unit.

Here we may discuss problems, solutions, & general fellowship.

*Apologies, I have no idea if this is MTCB, MTCD, or FYT head unit but it runs the snapdragon chip.

PROBLEMS / BUGS

:

1) Joying continues to keep bluetooth locked down. Meaning you cannot pair anything except a phone to the device. CORRECTION: w/ the bluetooth set to 'normal pairing' which is a new option available on a recent update Joying announced, I am able to connect to my OBDII bluetooth dongle. HOWEVER, I cannot pair to any other bluetooth devices like a keyboard, my rock lights / underglow, my LED air vents which are also bluetooth which would allow me to change the colors of them, etc...

2) If you have an amp for your subwoofer, and you fade to the front it will take gain away from the subwoofer. If you fade to the back it will increase gain to the subwoofer. This is not good if you're trying to gain match your amp aka tune your amp to make sure no clipping goes to your amp.

3) When starting the vehicle the reverse camera will be upside down. After allowing a couple of seconds for the device to fully boot up you have to come out of reverse and then go back into reverse and the reverse camera will be in the correct orientation. *UPDATE* Thanks to @rs200z a fix for this is to put the head unit in standby mode when you turn the car off. Now, if the battery voltage protection kicks in the head unit will boot from the beginning and thus this problem # 3 still persists but I haven't had that happen unless I don't drive my vehicle for a couple of days.

4) They removed the app for the dedicated reverse camera that was on the 2021 Joying headunit. This is very unfortunate it because people like me go camping and load up their trunk in their SUV to the roof so the rearview mirror is not functional. But w/ the 2021 Joying Head unit I could turn on the reverse camera even while in drive to see what is happening behind me.

5) AR camera app is now showing a smaller view of the front and rear cameras since the latest update.

6) AR camera app is not seen as it's own dedicated app in multi-screen.

7) The volume overlay that appears when you adjust the volume is huge and takes up too much room on the screen. The 2021 volume overlay was much smaller & at the very top of the screen only taking up very little room. As per @rs200z on his post here this seems to have been fixed by Joying.

8) It will not allow you to connect your phone as only a media device. It forces it to connect w/ phone connection, forcing you to take calls on the head unit even if you don't want to.

9) No way to put head unit in sleep mode (when the car is off) without also forcing the AR cameras to record activity. Thanks to the discovery from @rs200z on post #17 below, it is possible to put the head unit in sleep mode w/o also having the cameras record.

10) File manager that comes pre-built into the software does not work for Nova (or any other app) forcing you to download a file manager app from the play store.

11) JOYING LAUNCHER: Spelling of DIAL tile is incorrectly shown as "DAIL"!

12) JOYING LAUNCHER: Default MUSIC app cannot be changed despite being changed in settings under COMMON. It will only launch the in-built music app regardless of the app assigned in settings. For example, if I set YT Music as the default music app in settings the launcher tile will still launch the inbuilt music app and ignore the change.

13) JOYING LAUNCHER: In-built Music app will auto launch on every reboot in certain circumstances. It can be unstuck by turning ON 'Navi on boot' setting and then turning it OFF again. This appears to 'clear' the launch on boot setting.

14) JOYING LAUNCHER: Speed in Speed tile is shown as Km/h only and cannot be changed to mph.

15) ZLINK: CarPlay GPS is unusable. GPS works perfectly in Android Automotive, but when using ZLINK Apple CarPlay it loses the GPS location very frequently, making GPS apps in CarPlay unusable.
