had you do a reset ? have you have contact with joying support to replace your unit ?
[FYT Android Head Units] victorvcunha:
Try another trigger, bluetooth works of a different way in the Joying firmware, try "USB Connected" instead.
[FYT Android Head Units] CZ Eddie:
Is there a connection somewhere to add an external wifi antenna?
[FYT Android Head Units] rigattoni:
No, not needed in a car.

Even on the backseat the connection is good enough.

My phone in the trunk in my backpack and the connection was okay.
[FYT Android Head Units] CZ Eddie:
You may not need it but I do.

I'd like to get a stronger reception of my home WiFi so I can have a smoother/better remote desktop connection to the Joying from my PC in the house.
[FYT Android Head Units] julien_blanche:
Stock WiFi antenna is limited within the car inside and wife speed drops dramatically when you turn on the Bluetooth as well, in order to prevent that and extend the range and speed you may get a WiFi antenna and its connector (attached). To connect it just find the head unit WiFi cable and fit it to the connectors + and - poles. I tired this method and result was impressive.
[FYT Android Head Units] CZ Eddie:
Thanks!

I don't remember seeing that option when I installed it but I'll look for it in a couple weeks when I pull it back out to finish the install. :good:
[FYT Android Head Units] c0rnelone:
Does anyone know which poles of the 3.5mm connector use for the mic? Im trying to get my OEM car mic working (2 poles) and i was trying to go for the adaptor path.

If i cant find an adaptor i would cut the conector and put the one that comes with the joying mic.

I read somewhere else that it was using 2 ring and sleeve. (Tip Ring Ring Sleeve)

[FYT Android Head Units] KillerFu:
Just installed mine! This thing rocks! Just need USB tethering and Bluetooth to work...
[FYT Android Head Units] Cr4z33:
Maybe it's because of your Wi-Fi router/AP?

I get a very good Wi-Fi connection between car and router (about 5-10 meters away).
[FYT Android Head Units] lexuz:
With mine it gives full strength connection but most of the times the download speed is just way too low. If I use my phone next to it the phone downloads great. Going to try the wifi antenna as well.
[FYT Android Head Units] Crimson Flam3s:
I connected 2 different types of usb controllers and it seems like they are not being detected.

My ps3 controlled does work though although I prefer the snes style controllers for emulators, it's a shame they don't work for some reason.

Any solutions?

[FYT Android Head Units] D4rk_Seraph:
Hello friends, here in Brazil these units with Intel Airmont are being sold with 2gb LPDDR3 RAM instead of 4gb LPDDR4. Will they work well with 2gb RAM? I'm thinking of buying one of these units for my 2012 Ford Focus but I'm afraid that they cant perform well. What do you think about?
[FYT Android Head Units] CZ Eddie:
I wouldn't call it a deal killer.
[FYT Android Head Units] julien_blanche:
I would say that stay far away from joying products but if you insist to getting one then 4g ram would be a reasonable choice in long term hence android system is ram hungry and that hunger is getting bigger day by day...
[FYT Android Head Units] D4rk_Seraph:
The problem is that this unit with 2gb RAM is the best option Ive found at the moment, there are no 4gb ram devices right now in the brazilian market for MK3 Ford Focus. At the moment I'm using a S170 unit with Intel Sofia and 1gb RAM and I'm getting nervous of the slowliness of this unit.
[FYT Android Head Units] julien_blanche:
people get nervous with joying all the time whether it is 2/4 gb ram or spdif output or intel cpu and goes on...with 2gb of ram it does not worth the upgrade believe me..

Have you considered other px6 products with international shipping ?
[FYT Android Head Units] kpitao:
hello all,

Is anybody was able to successful use the steering wheel controls with this unit? I have a Dodge Durango and I have 8 buttons on my steering wheel and I can only setup 2....

[FYT Android Head Units] CZ Eddie:
Anyone know how to connect a Bluetooth device other than my phone?

My phone pairs fine, but I cannot figure out where/how to connect my bluetooth volume buttons thing.

https://www.amazon.com/gp/product/B07JQ8Q6X6/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

There is no "Bluetooth" anywhere in the settings that I can find?

The only Bluetooth I find is the Bluetooth "app" that lets you pair your phone.

And when I click "scan" in that app, it never finds my bluetooth device.
[FYT Android Head Units] millab:
Sorry but this just won't work. The bluetooth on these head units isn't part of the Android system, it is separate and only supports audio devices and OBD-II receivers.
[FYT Android Head Units] CZ Eddie:
Geez.

My USB connected volume knob won't work.

And now the BT connected volume knob won't work.

And the freaking buttons on the left side of the Joying are hit'n'miss.

I wish I hadn't missed my return date on this thing.

Thanks for letting me know.

It really sucks having to pay extra, extra, extra attention just to change volume.
[FYT Android Head Units] Guyzer73:
Hi Julien,

I tried this and neither of them worked I placed the 'mycar' folder in the internal memory and the images were not recognised, despite being in png format size 1280x48

For the boot animation I can't copy to the system/media folder as it's write only and requires root access. :confused:

I know on my old seicane unit the mycar folder method worked and for boot animation I needed to access a separate apk...

Any idea where Ia'm going wrong?? HU is not rooted.

Cheers :good:

Guy
[FYT Android Head Units] julien_blanche:
If the boot logo picture could not be changed then try to change it to a stock logo from the settings menu and restart the unit then put the mycar folder in to the internal memory and go to the settings and try to change it again..

If you want to change boot animation logo you have two option either you can root you unit and place the file inside the media folder or put the boot animation file to the root of the usb stick along with the lsec6521update file, head unit automatically detect and restart itself and install the animation file.

or make your life easier with [MENTION=2550900]surfer63[/MENTION] 's JET apk

I'm unable to get step 5 to work. Should it prompt me to download contacts or do I need to do this manually? I tried re-pairing my phone with bluetooth but can't get it to download contacts. In the bluetooth phone app there's an icon that looks like a download arrow, but pressing it does nothing. Thanks for any advice you have!

EDIT: Solved by turning on on contact sharing in the phone setting > connected devices > joying unit.
[FYT Android Head Units] LugnutWe:
Have you tried changing the touch area for the buttons. The default was small, I believe you can go up to 50x50 pixels. That made a huge difference for me - when I had mine.
[FYT Android Head Units] tangcla:
There's a blog post about this on the Joying website.

I also noticed an August firmware release.
[FYT Android Head Units] julien_blanche:
Even when you change the touch area of the left buttons you have to press exactly precise area to make them work. I could not find a solution for this.

Even for this problem i could return this piece of sh.t head unit without thinking because this is only happening on joying product.
[FYT Android Head Units] tangcla:
Are you sure you saved the settings? The touch input configuration is hard to define and sometimes does not save.

After adjusting the touch delta, this fixed a lot of problems for me.
[FYT Android Head Units] julien_blanche:
I am sure that i saved but i will try one more time to adjust, thanks for the heads up.
[FYT Android Head Units] surfer63:
Unbelievable.

So many issues with this 9853i unit. I'm glad I'm still on my PX5, which does function fine. If I (ever) get a new unit it will either be an Atoto A6 Pro or a Dasaita.

Atoto is still on Android 6 but it's through and through developed, very stable and matured, and still fully supported with regular firmware updates.

Dasaita for the simply better build quality (therefore slightly more expensive) and universal MTCD/E architecture.

Of course: You might only see the 50 users with issues here and not the 10.000 users without issues, but still....
[FYT Android Head Units] rigattoni:
I don´t have any of these issues ever seen on my device.

Yes, the touch config of the "On-Screen-Buttons" needs some attention, but this is written in the documentation that you need to choose a wide area not just the small finger tip. On top you are able to correct the area in the application.... and you need to save it properly. It´s saved as area!

May be that the firmware is not yet optimized completely, but - sorry to say - a lot of issues are sitting in some distance to the screen and are not related to the unit.
[FYT Android Head Units] julien_blanche:
The issues that listed in here because of some reasons and the reasons have some logical explanation. If somebody stating an issue which related with the unit or software or support then there is an issue obviously. And depth of the issues related with how an user is interacting with the unit as such is s/he an expert or regular person in terms of audio/video/navigation/audiophile categories and how often use those features.. so maybe somebody use this unit as an just the music player or someone use this unit as an multifunctional device..so clearly the unit have some serious problems otherwise we wont be here discussing about something...

Cheers..
[FYT Android Head Units] kpitao:
I have this unit for about two months and I only have one issue, but I cannot blame Joying... my only issue is with the steering wheel controls but I'm using an old steering wheel control interface, I will buy a new one and see if makes difference....

and one app that does not work in this unit.... since I'm rooted I will install nokill server and xposed to try to use that app...

They have MCU and ROM updates depending on screen resolution and DSP.

Edit my bad the lastest firmwares on the page at the moment are only for the PX5 units.
[FYT Android Head Units] CTDPeti:
of course, i switched rds on. in this app i scanned and saved selected channels but i couldn't see neither saved channel name nor frequency on the list in the left side. and the pty and st buttons below are blind. On the right side i saw only frequency, no other information. I don't understand why, may because of 8.1?

Thank you for your help Surfer!
[FYT Android Head Units] surfer63:
Yes, that must be 8.1 then.

So like I mentioned earlier: Decompile the radio apk from 8.1, change the package name throughout the entire app, do your modding, recompile.

The screen of my unit broke. The unit itself is still running (I can hear the radio), the screen still reacts to swipes but it only shows black & white artifacts.

I'm trying to figure it out with Joying support. Did anyone else have such issues with Joying units before? Maybe specifically the new Airmont ones?

I will try this solution. Then i share the result.

Thanks foi sharing!:D

Check the flat cable. It's a problem of the connection between the main board and the board of visualiation. Check if the same happens with the front hardware buttons.

[FYT Android Head Units] IG_Vasilich:
1. PC: Download and unpack the archive Root.zip (14.78 MB, see attach)

2. PC: Open the archive "6521_1.zip" of the stock firmware and get "boot.img" from there.

3. PC->HU: Copy the file "boot.img" to the HU.

4. HU: Install “Magisk Manager” on the HU https://github.com/topjohnwu/Magisk/releases/download/manager-v7.0.0/MagiskManager-v7.0.0.apk.

5. HU: Run Magisk manager (internet must be available), select “Install> Install> Patch kernel image“ and specify the path to the stock "boot.img". Magisk Manager will patch the boot and put the file "patched_boot.img" in the device's memory.

6. HU->PC: Copy the file "patched_boot.img" from HU to PC.

6a. PC: Put the file "patched_boot.img" in the archive (with replace) "6521_1_input.zip" (compression "Normal").

7. PC: Archive "6521_1_input.zip" must be signed with a test key and renamed to "6521_1.zip" (archive already contains SignApkV2 signature, you only need to run “start.bat”, after finishing it you will get file "6521_1.zip". For SignApkV2 to work JDK has to be installed and configured (“java -version” from command line should report installed version. If not – check environment variable “JAVA_HOME”, and “%JAVA_HOME%\bin” should be present in the PATH env. variable); I recommend to use JDK 8 https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)

8. To install patched ROM, copy the minimum set of files (new “6521_1.zip” and “lsec6521update”) to USB flash drive, insert it into the HU. Firmware update will start automatically.

All this is just a translation from 4pda, i have no responsibility for any bricked device!
[FYT Android Head Units] surfer63:
This user jp2008 uses an “lsec6521update” that is different from the ones in the Joying 9853i firmwares.

- Is it simply different because it has been compiled on another system, but functionally identical?

- Or did he hex modded it so that the modded binary uses the test keys intead of the normal Joying keys for signature verification? If he hex modded it can he tell how he did that? Or is there somewhere a link on 4pda explaining this? It would mean that I might be able to do the same for the PX5 "sql6026update8". I already wondered how it was possible that he could do this with test keys. This was never possible on the Sofia 3GR and on the PX5, because those wanted the "original" Joying keys.
[FYT Android Head Units] IG_Vasilich:
as far as i understood, lsecxxx is not patched. jp2008 mentioned, that he tried to flash different ROMs using the same lsecxxx file.

"needed for update lsec6521update can also be taken from here <link>. No responsibility for damage! i have used different ones, and haven't seen any difference."
[FYT Android Head Units] DylanHarper:
I've got the 4g version and really struggling to get a decent signal whilst driving, WIFI is also weak compared to the PX5 which is PITA, I wish there was an option to change the display size, I find the icons too big !!

Apart from those issues, the SQ is surprising, i had a few px5 units in the past and couldn't get past the crap SQ,
[FYT Android Head Units] McMethylated:
Runs much smoother than the PX5 units

Much much better unit compared to the px5. Smoother transition between apps, better temperatures, faster and heaps more. If you're unsure which one to get, get the intel over the px5. I have both and intel one runs better.
[FYT Android Head Units] PaulBorges:
SQ=sound quality?

For me one of the best improve is the DSP.
[FYT Android Head Units] breevesdc:
Hello. Am I really the only one experiencing this? I only did 3 things. Install the latest ROM, followed the instructions on xda to root the device, installed Xposed modules. Other than this, I've done nothing to alter the unit. It's a really weird issue. I'd hate to have to give up the seamlessness of using Chrome on my computer, phone, iPad and car. Anyone else experiencing this or have any thoughts on what could be causing it? Thank you.

Brian
[FYT Android Head Units] surfer63:
There is currently no Xposed suitable for this unit.

Feel free to experiment and share your results :)

But be careful not to (soft-)brick your unit.
[FYT Android Head Units] CZ Eddie:
Is your JoyCon working properly with the Joying?

I was thinking of getting one and fabricating some buttons to control volume with.

And maybe add other buttons to assign functions to.
[FYT Android Head Units] hawkjm73:
Yes and no.

The JoyCon hardware works flawlessly. Every button press translates to a keyboard entry on the headunit exactly as specified. The trouble lies in getting Android to do something in response.

I'm using AutoInput in conjunction with Tasker to read the keypresses. That, though, requires an accessibility service which, of course, gets killed every AC-OFF. Fortunately, AutoTools also exists. It allows Tasker to start accessibility services programmatically. It requires a permission to be granted via ADB shell, which Tasker itself can do if there is root access. Once granted, root can be removed.

Before Tasker can start the service, AutoInput and AutoTools have to be launched once. I'm currently troubleshooting how to do this, but this thread has a starter app which allows you to launch whatever app(s) you like at ACC-ON. Page 2, I believe.

https://xdaforums.com/android-auto/android-head-units/joying-vw-universal-steering-wheel-t3944201

The GitHub there also has a remote app which can be used for volume control. It replicates the way the native apps talk to the mcu.

Side note: I did try setting the JoyCon to emit standard Android media control, but my head unit ignored them. Your milage may vary.
[FYT Android Head Units] spiker88:
I just received a replacement head unit (not including screen, sorry I'm not sure what we call just the box in the dash). I have the 1280*480, 4gb/64gb with old ui from Amazon bought 2 weeks ago.

Joying claims this new one is an "American mental box" that will get better cell service than my current "European mental box". I'm skeptical but willing to see if it is compatible with more US LTE bands. I get limited service with my Google Fi (T-mobile) sim at the moment, it works when I have Band 2reception as expected. Joying support said this version not available online, they can only sell it directly. Despite asking multiple times which bands it would receive I couldn't get any details from them, but they sent it so I figure why not try it?

Probably a noob question: Is there a way to back up the old unit (apps, settings, etc) and restore the new one to the same state without having to do it all manually?

Thanks for the guidance.
[FYT Android Head Units] julien_blanche:
There is a google backup option if you use it then switching could be easier to new unit. Could you share your new mental box pictures inside of the board if you have not fitted to the car already ?

Cause they are changing mental box design every month and we don't know whats change..
[FYT Android Head Units] spiker88:
OK, if google backup is the best option I'll go that way.

The good: I am receiving full 4G on BAND 12, where I used to get no service (band 12 is one of the main t-mobile bands which wasn't supported with the original unit). I activated my Fi sim and had data service immediately. Pretty cool!

The bad: The screen isn't working correctly. Colors are way off/inverted, it's pixelated more than usual, text hard to read. It looks like it did temporarily while I was setting up my original unit and didn't have the screen connector in all the way. But this time it is seated well and I re-seated it multiple times. Could this be a compatibility issue of the screen with the new box that I might fix with software, or is it definitely a hardware issue?

As for internal pictures, one of the screws for the lid has an anti-tamper sticker on it dated Aug 19, and if this screen thing is real I'll be sending it back. So I'm hesitant to mess with it.

New System Info and MCU Version dated 2019-08-15
[FYT Android Head Units] julien_blanche:
If you are still having screen colors are inverted issue then this is a hardware related with bad/cold soldering which i had before.

Either you should send it back to the china or if you have some soldering skill then try the re-solder cpu pins to the motherboard.

Good luck.
[FYT Android Head Units] Caroline_Don:
Hello friend,

Could you please provide the system information of your head unit that supports ok google to commend the bluetooth call, I will appreciate. Thank you for your help in advance.
[FYT Android Head Units] Guyzer73:
That would be logical as AA is located on the phone not the HU. HUR only acts as a facilitator to stream AA from your phone, hence won't pick up music files from anywhere but the phone...

If you want to run AA in self mode from HUR on the HU you may get AA/ HUR to 'see' the music on the connected hard drive, but you'll lose some functionality especially regards calls and messages.
