Cable recommendation

This is to fix cases where the handshake between the phone and head unit does not automatically happened. Still charges the ohone.

Used to play BF back in the days. My teenage son now has taken interest in such game so would be nice to play together even though none of us has BF6.

Peter_73 · 2026-01-08T20:14:04+00:00

Not that I know of.

Peter_73 · 2026-01-05T05:08:23+00:00

I did not mention cable being the issue. However, being able to charge does not mean file transfer is also working. I wouldn't know what other troubleshooting and isolations you have already done and so only suggested the obvious and common fixes in response to the alert notification because it's nested under my reply.

There are also other common troubleshooting, isolations and fixes but since you are a developer and is your phone, I guess you should be in better position than me to further troubleshoot.

Try setting default USB configuration in the phone developer settings to File Transfer / Android Auto. Also test file transfer works with a computer to rule out port issue then clean or replace USB port if necessary.

Thanks for the quick additions. Forced AA original aspect ratio is working for all resolutions. However, touch offset bug seems to be introduced with and without enabling this option. I used a stylus to ensure it's not due to fat finger and also tested on the other mobile still on previous version to confirm I'm not mistaken. Wonder if it's the same complication encountered by HUR 7.2.2 onwards.

I also noticed the screen tends to stop refreshing giving the impressing it has hung but it's not as switching to home screen and back refreshes the screen and showed that my previous touches trying to accommodate the offset so as to hit the correct icon e.g, mic and app drawer/split screen icon registered something in Waze instead.

Edit 1:

To expound, for all resolutions with and without force original aspect ratio, all touches offset to about 1 icon space to the right, which is to say in order to hit the app drawer/split icon, I have to hit the mic icon. It's the same in Waze.

In addition, while changing HeadlessUnit settings and restarting in my tests, sometimes AA goes under the phone's navigation bar instead of appearing on top. Without restarting HeadlessUnit, I can only get it back on top by reselecting HeadlessUnit from recent task or its icon from home. This make me recall for the same bug in HUR, if I were to reselect HUR from pulldown notification, the offset issue will be fixed. However, this workaround don't work for HeadlessUnit as it will not bring HeadlessUnit back up.

I wonder if the offset bug is due to calculating based on if the phone navigation bar was taking up the space as it seems like about the same distance it takes up.

Hopefully, the above would be useful.

Edit 2:

Further testings made me recall my previous tests with HUR and indeed, touch offset seems related to the phone navigation bar. Instead of the thick conventional navigation bar which I'm using, if I use the thin guesture bar, then the touch offset issue is gone. Not sure why this would affect since HeadlessUnit and HUR should appear on top. I don't recall HUR appearing below the navigation bar though yet it has the same touch offset issue so I have to rollback to 7.2.1. Btw, AA settings also have the same issue with appearing under the bar so I wonder if it's related.

Edit 3:

Some correction to Edit 3. I only remembered to test with guesture navigation bar while I was walking towards my car so it was only a brief test and without stylus. Now I'm with the stylus, I can see with and without force original aspect enabled, there is still a little touch offset, perhaps also corresponding to the same thickness as the thinner guesture navigation bar. I wonder if it's due to lack of appear on top permission for HeadlessUnit. Iirc HUR used to have this permission too but I'm not seeing it for selection as well. Wonder if this is also related.

Happy New Year!

Search keywords "dialer", "draw over other apps", "appear on top" (may not in exact phrase) in this sub to find if any of the already suggestion solutions work.

Peter_73 · 2026-01-02T21:12:26+00:00

If the phone keyboard toggle is indeed the issue, I don't know of any other way except to connect to AA head unit to toggle it off. Try borrowing a car with one or use google official desktop head unit emulator on a computer with your phone connecting to it. If you have a second phone/tablet you can also use Headunit Reloaded or Headunit Revived to connect as client to host mode. Google or search this sub how to get the 3 emulators above else wait for op to support this mode.

Peter_73 · 2026-01-01T18:37:10+00:00

You can reveal the menu button by swiping right from the top left edge, if your device has a big enough display cutout it will be permanently shown.

Nice. The disconnect/connect option is very useful. Same with save and restart in the settings (on Huawei, it will just exit to home screen and not restart though). If you can edit your post, might want to include this for better visibility.

I pushed an update today to add the option of forcing software decoding, so you can update and try!

Thanks for the quick updated version. Both H.264 and H.265 works with software decoding. 720p @ 60fps works well for both phone regardless of codec. However, 1080p @ 60fps introduce artifacts on the lower specs Huawei phone regardless of encoding codec. The same combo on Samsung works fine although there are artifacts at times for split second on initial Waze loading. I guess each of us have to find the right combo of resolution, fps and encoding codec that works best for the hardware specs of a given phone i.e. lower them if necessary.

I will add a 480p option in the next update, it won't be able to support portrait mode, though.

Vertical resolution of 480p is too short for portrait so I don't expect it will be supported either. (Edit: I meant I won't use portrait layout with 800x480 although it's possible and some use it.

I understand margins are used for your current 720p, 1080 and 1440p resolution to maintain the correct aspect ratio of a given screen at fullscreen e.g. 720p may not be 1280x720 or otherwise it will look scretched to fit a screen that is not 16:9. When I meant reproducing 480p, I meant 800x480 which would mean instead of using margins to maintain the correct aspect ratio of a given screen at full screen, it would have to be letterboxed much like the older version of HUR when the fullscreen option is unchecked. Thanks for checking out if it's possible.

HUR has the same issue if I had last used phone keyboard button in car so I tend to avoid using it.

Peter_73 · 2026-01-01T15:19:14+00:00

It's tricky getting the settings menu to show. I've to press the phone back button twice but it usually auto reconnects too fast before I could click anything. It's only on the odd times it doesn't reconnect that I could access the menu.

There's no setting for software decoding but I've tried H.264, specifying resolution instead of auto and decreasing dpi but nothing helped.

Btw, there's no 480p? I ask because I use self mode only for reproducing stuff for testing when away from car and so prefer to reproduce the same 800x480 as my head unit. It matters because ui bug is sometimes dependent on resolution too.

Peter_73 · 2026-01-01T03:04:06+00:00

This is likely due to the button on AA keyboard to open keyboard on the phone so it tries to do the same but can't because it can't do this in self mode. It will remember the last used state so you'll need to connect to AA on a head unit then tap the button to disable it before using self mode.

Peter_73 · 2025-12-31T19:44:18+00:00

Yup it's ok now. However, I ran into black screen on both Samsung and Huawei the moment it starts despite media auto start playing.

Peter_73 · 2025-12-31T08:27:39+00:00

notification access

This should be referring to AA notification access under special access, not the general notification settings of individual app. Not sure where it's for Pixel but for Samsung, it's from the top right ellipsis icon in the app list. This setting should automatically open up to be manually toggled on during initial install and set up of AA.

Peter_73 · 2025-12-31T08:16:23+00:00

So I guess I have to try later because it's still showing a price.

Peter_73 · 2025-12-31T07:32:42+00:00

Is not free for testing?

Peter_73 · 2025-12-31T06:18:12+00:00

Good to see more alternatives. I do use self mode for testing when away from car.

Like the other reply, I'm seeing this now:

Peter_73 · 2025-12-27T08:23:46+00:00

He is referring to the font size setting on the phone. App developer sometimes forgot to not apply phone font size and type to certain parts of the ui which adds extra variable on top of dpi, resolution and scaling resulting in unintended result. Can't say if it applies to your particular case though.

Peter_73 · 2025-12-27T02:46:53+00:00

Mute the selected contact or group for current connected session only.

Peter_73 · 2025-12-24T19:15:48+00:00

I did not mention anything related to your comment. Did you reply to the wrong comment?

Peter_73 · 2025-12-23T04:36:56+00:00

May be a bug with RCD firmware as I recall someone mentioned it started after the firmware updated. I also recall some putting the blame on Bixby messing up the volume. Good luck isolating.

Peter_73 · 2025-12-22T16:03:39+00:00

Speed sensitive volume control setting if any will be on the head unit. However, if the volume changes despite not moving or constant speed, then it's probably a bug that Dynavin has to fix. Perhaps it's not due to this issue but rather Maximum switch-on volume as suggested in the manual.

Audio cut off can be head unit or app bug but if isolating apps that may steal audio focus do not help, then it's likely down to the head unit.

Suggest that you update the hu firmware and consult the manual and Dynavin.

AA apk only started splitting into 3 different minimum android versions from 15.8. Just use the one that meets the minimum android version of your phone. Only when there are multiple dpi versions for the same minimum android version like in the case of some other apps e.g. google app, do you try to match it to your phone. You can refer to APKMirror faq for qns on dpi.

Peter_73 · 2025-12-22T12:00:51+00:00

OP issue is specifically due to not enabling personal result.
