Mod translation: It may be like this, I have been a car audio installer for 24 years professionally and I believe that it is the first Android unit with good hardware, good features and a really well developed sound in addition to software agility and the separable screen of the unit is a luxury correcting the Bluetooth compatibility and adding a minimum of customization would be a 10

Puede ser asi yo soy instalador de audio car desde hace 24 años profesionalmente y creo que es la primera unidad android con buen hardware buenas prestaciones y un sonido realmente bien desarrollado ademas de agilidad de software y la pantalla separable de la unidad es un lujazo corrijiendo la compatibilidad bluetooth y agregando un minimo de personalizacion seria un 10

I am using the factory (amplified) shark fin antenna. I am getting plenty of stations (>20) in my area. The RDS function works as expected. But I observe no difference when toggling between STereo and MONO (all really sound like mono to me).
[Android Head-Units] nFiniti:
As I've mentioned about the Bluetooth, its functional. You just need to use the Correct BT device since your unit has 2. The Joying Bluetooth App is limited to phone and a few OBD2 Devices. BUT the SYSTEM Bluetooth is completely different and you can connect all things from Gaming Controllers, Mice and Keyboards, etc. This System Bluetooth will have a completely different name from your Joying BT App. The only major issue with using the System Settings BT is there isn't any development past BT AVRCP Version 1.4 which is slightly limited on information shared. So when syncing a BT Device, you can't really be around many because they all are named NoName. So you must guess which one is the correct device. But other than that I haven't found anything that doesn't link up to it.

If I can get a screen recorder working I'll take a video with a few devices.

For anyone considering an amplified FM antenea, there were relatively few out there that had any decent reviews. So for $11, I figured I would try this one.

Installation is easy, but results are meager to say the least. I did pick up a couple stations weakly. I would not recommend an amplified antenna as a cure to Joying crappy FM problems.

No HD, no RDS, and a real sucky interface - face it, Joying just sucks for FM. :poop: I had a Dasaita before, and FM was much better. But Android Auto was sucky on Dasaita whereas Joying is reliable. I use AA every time, not FM.
[Android Head-Units] marchnz:
It's not AA, it's some kind of kanged emulation. If using AA full time, curious as to why you didn't buy a genuine AA - google sanctioned - head unit?

I will get to it as soon as I can. I don't have much time to mess with it right now before I end up falling asleep at night. Its on a 4ah Battery thats bench testing on my dining table next to my laptop. I'm super busy with work and new house projects so I'm not spending much time on the radio but I will try to get one soon. I will tag you.

Thanks, I was planning on trying some sort of amplified antenna just for the hell of it even tho I don't care for FM much. Definitely don't care for Android Auto or CarPlay but I do have hundreds of gigs of high quality FLAC Discographies and LTE Internet on it.

However, As you mentioned about No HD or RDS and Sucky Interface. On my 2020FYT Unit I bought the very popular NavRadio+. Its the best FM App for Android Radios bar non! HD, and RDS if its available. It doesn't work/it isn't ported to the Snapdragon units yet so I just finished sending an invite to the Developer Kaotic who is the creator of NavRadio+ to the Snapdragon community. I explained a few of us are wanting to attract the attention of a few good developers to help with this unit since its the most powerful to date. So Fingers crossed. I don't listen to FM Radio at all but I still want my unit fully capable. Or else, whats the point?

NavRadio+ - Apps on Google Play

[Android Head-Units] tarzan_nojane:
The antenna amp built into my 2014 Toyota GT86 seems to function as expected once I connected its power lead to the blue pin 6 wire from the Joying 20-pin connector. There is enough signal sensitivity - I am getting FM stations from more than 100 miles away - but there is no evidence of either FM Stereo or HD. The RDS data (in the US I believe this provides song title/artist and stations-related text) feature seems to be working.

Joying promotes that these head units are fitted with the Skyworks Si47925 - High-Performance Automotive AM/FM Radio Receiver and HD Radio™ Tuner with Audio System.

"The Si47925 is among the most integrated monolithic ICs in the industry with the smallest external bill of materials. The Si47925 sets a new standard for automotive broadcast reception by integrating analog AM/FM receiver and digital radio tuner with audio processing. It features DRM, Audio DAC. WB, Audio Post-Processing, and HD Radio. The integrated audio processing sub-system provides a complete solution to synchronize, process, aggregate, and distribute digital and analog audio signals in the head-unit. The Si47925 includes a set of audio software products and tools available for license, providing a complete solution for audio post-processing in the radio."

Based on what I have encountered so far, it wouldn't surpise me if Joying is not paying the license fees and is unable to unlock all the features of the IC. Could ba a sanctions issue, could be counterfeit - we will likely never know.
[Android Head-Units] Flame Red:
This makes me wonder if the antenna supplied by Joying is just junk, and perhaps there is a better antenna available that will cure the FM issues some of us are having?
[Android Head-Units] CCJ22:
Seems with the latest firmware update for the 1080x1920 devices I am not longer able to adb into my joying HU.

Anyone know of a work around?

I have developer mode enabled and usb debug is turned on.
[Android Head-Units] CCJ22:
That would be great to see how you are managing to get connected to any bluetooth device. :)
[Android Head-Units] PrinceLc:
Try adbwf as code
[Android Head-Units] CCJ22:
Interesting!

Where do we put that code in?
[Android Head-Units] AlgoryThm1st:
That's the best thing I read since the day I bought the HU. Thanks man, it will help all of us A LOT!

If some of you have reception issues (NOT the HD/Stereo issue, as that seems to be a different problem), the cheapest solution that crossed my mind is a wideband LNA from aliexpress. That thing has an average 30db gain across the whole spectrum, from MF to Upper UHF. Meaning it's not only for FM but you can also listen to AM radios that are hundreds of miles away. Day and night compared to cheap preamps included in those amped antennas you buy on amazon.

I had one around, bought years ago for my PC SDR, just tried it and it works like a charm.

If you are interested, just look for "0.1-2000MHz RF wideband amplifier LNA" on Aliexpress. And if you're not into electronics and you want to avoid soldering stuff, make sure you buy one that's already assemblied, not just the PCB.
[Android Head-Units] PrinceLc:
As factory code
[Android Head-Units] CCJ22:
Unfortunately on the 2023 Joying snapdragon unit you're only able to put in numbers 😞
[Android Head-Units] nFiniti:
Unfortunately that idea was shot down fast. He seems to be having issues porting the app to a few other devices and don't believe he will ever get to the Snapdragon units. That's very unfortunate. Joying for sure won't do anything worthwhile. They have some good hardware and decent screens but they are Horrible with Software development.
[Android Head-Units] CCJ22:
Speaking of screens has anyone seen their QLED screen they recently launched? Cause my 13.3" screen, during Black scenes, has light leak.

Ah ok I have an Eonon 665 with HCT MCU and with code adbon you open Dev option and adbwf ADB over WiFi active
[Android Head-Units] nFiniti:
Well FML!!!! Seems Joying has ultimately screwed the pooch and I possibly might be demanding a refund or a replacement with a FYT Unit rather the Snapdragon. I am about to type up a very "Karen" style email to them. Why? Because everything I've been saying about Bluetooth seems to not work with the Snapdragon unit. My 2020 FYT, no Problem, My previous units including Xtrons, No Problem. I can pull my 2020 Unit out of the box and video it to prove what I'm talking about but I just attempted to make a video with this 2024 Unit and quickly had to stop because nothing is connecting.

I wanted the Snapdragon unit because of the Snapdragon processor. But now I'm seeing that the FYT unit is 100000x better. Full Root and tons of cool kernal tweeks and other things you can do. NavRadio+ works flawlessly. Bluetooth works flawlessly. Yep, here we go!
[Android Head-Units] AlgoryThm1st:
Well, if it's not much trouble, please add another Karen line like "if you don't release the fully unlocked, untouched GUI version, some good people in a forum will massively upload videos with all the negatives of this HU and guess where your sells will be in a couple of months...".

What they've done to this otherwise excellent specs machine, is just terrible. They've destroyed maybe the most powerful unit yet with the crappiest software moves I've seen in my entire life.
[Android Head-Units] nFiniti:
I told them I cannot endorse their item as they asked me to in their first email to me when I bought this less than a month ago. I told them the reason why I cannot endorse it to the car and xda forums is due to all these reasons, Locking down Bluetooth and the rest of the UI basically crippling what could be an amazing Android System. If they cannot provide an update with at the very least a fully functional Bluetooth fix, I want a refund or a replacement for a non Snapdragon FYT unit with equal memory and ram. They asked me which one. I will respond and try to give them an idea on how many people are looking to other brands because of all these issues. I am.

I want full function. One of my biggest issues with joying is the lack of an accelerometer and the sensors that come with like a Gyroscope. This helps apps like Navigation understand which direction you're actually pointing. So it doesn't think you're driving sideways. Teyes has one built in. If they offer a refund I may take it and try someone else out.
[Android Head-Units] nFiniti:
I'm bad with video's so I hope this will suffice. I edited Life's original Root How To with some additional information that could be helpful to those who couldn't understand.
[Android Head-Units] tarzan_nojane:
My unit did not come with an FM antenna from Joying, only an adapter harness to connect the OEM antenna to a conventional plug for the HU. Plus a lead to connect to amp power for the OEM powered antenna amp.
[Android Head-Units] nFiniti:
The FYT Units. The Previous Model Joying Units that DO NOT have the Snapdragon Processor. They will have Android 10 only, No Fake Android 12. Which is a better thing, the FYT Units have much more development behind them. And the Bluetooth is split into 2. The Joying APP which you Normally would use to connect a device on the Joying Radio, OR the Android System Settings Bluetooth Tab. Joying Blocks the System Settings for their own settings window. But there are ways to get to the Android System Settings. One was using Car Launcher Pro, it gave a selection to open that settings page. But on the New Snapdragon unit, Joying has found a way to block that as well. Or you could use an app like Shortcut Widget to access the System Settings, then you would find a completely different, 2nd Bluetooth Device! 2 Different Names, Bluetooth 1 and Bluetooth 2. Bluetooth 2 from the System Settings, not the Joying App, Would let you connect any device you want. The only limitation is the development was limited and it would only show "NoName" for All Devices, so you would need to guess. But I had Xbox Game Controllers, Logitech Mouse and Keyboard, HPTuners V3, OBDX Pro VT, OBDLink, and I even linked up with a Bluetooth Speaker. No Problem!

Full Root and many kernel upgrades are available for the Android 10 Devices. I have 2 of them, a 2022 A10 Device and a 2020 A10 Device all from Joying and they rock!

I just told Joying via Email again that I would like to keep my Snapdragon unit ONLY if they will Give me an update to fix the Bluetooth Restriction. I know there are lots of other issues but unrestricted Bluetooth would be a very good way to keep me with the Snapdragon Unit. But if they cannot or will not provide a fix, then I will be requesting a Refund or a Replacement for an Equal Android 10 unit.
[Android Head-Units] Flame Red:
Interesting.

I replaced the antenna supplied by Joying with this:

The improvement was immediate and substantial. RDS began working. Not sure if HD is working as I don't see the usual HD indicator. Joying has this infinity symbol that appeared. Perhaps the infinity simbol is HD?

I have no financial interest in this product.

The lead is actually pretty short, so depending on your application, you may need an extension cable too.

You do have to play around with it to find the mounting spot that gets the best reception in your car/truck!

But it does make the FM work as it should.
[Android Head-Units] tarzan_nojane:
Can you hear any differences between STereo/MONO setting on a station with a strong signal? Also, it might be relevant to remind us of which Joying unit you are working with.
[Android Head-Units] AlgoryThm1st:
I contacted Hovatek and I'm waiting for his answer, about helping us unlock the device and build a custom ROM. I also invited him to this thread.

For those who don't know him, he's a developer from Nigeria and he has built the famous TWRP porter script, among others. He now works with a bunch of other people, also developers.

I already tried various tricks to install TWRP to our device, using his script but it seems Joying has neutralized the recovery image and boots into custom fastboot/recovery/update interface of their own.

Also thinking of moving to a new thread, strictly for Unlocking/ROM development for these devices and keeping this as a general questions/support thread.
[Android Head-Units] nFiniti:
Please Please Keep me in the Loop. I'm currently in talks with Joying about switching this unit out with the previous A10 Unit with matching ram. The Bluetooth Lack-Of-Functionality killed it for me. Its really bugging me. I have my LS V8 Bluetooth Device and other devices I was using on my 2020 A10 FYT device. And modding that one is simple.
[Android Head-Units] AlgoryThm1st:
Sure thing. I'm still waiting for his answer, as soon as he gets back to me I'll write an update here. Another strong asset for the team would be the guy known as alaskalinuxuser, but it seems I was too late. He's moving on, retiring from android development, as he wrote in his telegram group a few days ago. He's been a very good developer and extremely good instructor for years, I've learned a lot from his videos. Which by the way is going to remove from youtube, so anyone interested, this is a very good time to download them. I'm probably going to write in his telegram channel anyway, cause there are still lots of good developers in there.

But, just as a reminder to all the friends who read this thread, this must be a team effort in order to give fruits. Anyone who knows any good developers, please contact them and ask for help. Mediatek devices with strong bootloader lock have recently been cracked, this is a piece of cake for someone with even moderate development skills. It's just a matter of mobility from our side, contacting people willing to help.

I'm dreaming of the day (hopefully soon) I will see an unmodified Android 14 running on this thing...

Actually, with a very strong signal, I did not hear any difference, but my hearing is damaged from when I was a kid.

[Android Head-Units] sofakng:
What's the missing functionality?

I'm still debating whether or not to upgrade my 2021 Honda CR-V stereo to a Joying.
[Android Head-Units] nFiniti:
The Bluetooth is locked down fully on the A12 Snapdragon units. Where as the older A10 Units I could connect any device I wanted from Game Controllers, Mice, Keyboards and even my HPTuners or OBDX Pro OBD2 Devices. Now all you can connect is a phone and Joyings specific devices. No work arounds.

They are about to send me a shipping label to ship this 2024 A12 Unit back and they are going to swap it out with an equivalent A10 Unit. I gave them options to fix the bluetooth at the very least and release an update, which is just one of the few known issues and they turned me down and rather just replace it with another unit. They don't really care about software development and the customers.
[Android Head-Units] nFiniti:
And unfortunately, they just accepted my 2nd terms. Instead of providing the customers a fix for a few things they could have done differently, they have sent me an international shipping and customs label to return this device. I left them one last rant explaining that they should really read into what the customers are saying on the groups they are asking Us to promote them to. I know they don't care tho. Its just business to them. I will keep tabs on this to see if we can get developers in here to go to town on one. I really wanted to have the snapdragon processor. And now they are releasing OLED and high resolution screens. They just need to unlock some features that shouldn't be held back. And they need to add an accelerometer. And some clean launchers that aren't train wrecks.
[Android Head-Units] AlgoryThm1st:
As I promised, there's a new thread for ROM development next door: Here
[Android Head-Units] 5noc:
I'm unsure why everyone says that bluetooth is locked in these units. My old Joying with UIS7862 sis had the bluetooth locked and I only couldn make it work with my OBD2 dongle by changing a setting with a file during boot but that made the phone calls audio sound like **** for both me and the receiver.

I upgraded to the Qualcomm one as soon as they anounced it and my OBD2 (it's a K-tuner unit, mind you) and my dashboard LED lightning from AliExpress have been working wonders, plus phone audio sounds acceptable too (the quality expected from one of these things as it has a ****ty microphone).

I'm not writing this to brag, just saying that it works and there must be a way to make it work if it did for me without changing anything.
[Android Head-Units] PrinceLc:
Do you have a link for the led strip??
[Android Head-Units] 5noc:
I do indeed but I am unsure if I am allowed to post links in threads so I just sent it to you via DM.

Car Info app > Tire Information is giving me tire pressue values for the 4 corners of the car via CAN HI and CAN LO wired ti the CAN Bus decoder. But the values are in kPa and I can't figure out how to get these to display PSI. Everywhere else I seem to see Imperial units.

I have given up asking Joying for assistance. They have totally ignored my last 4 inquiries.
[Android Head-Units] De_Belg:
At least you got 1 station. I get no FM or AM stations at all.
[Android Head-Units] tarzan_nojane:
Does your vehicle's OEM antenna need power? If it is a shark fin or a stubby format, the original head unit was likely supplying 12V power to the antenna and you should make sure that your setup (blue wire pin 6 on the Joying 20-pin connector) is configured to do the same.
[Android Head-Units] De_Belg:
Well, my OEM antenna needs 12V and it is provided from the Joying 20p connector to the GT 13 antenna connector for my car. The OEM car antenna is a stubby.

My device has never been in the internet and out of the sudden they want a scam my activation after the update.

Without the activation there is a activation request with a QR code overlay on every screen right in the middle!

Unbelievable they are destroying their device more and more with their cheap software.

Does somebody also have uploaded the custom theme option firmware somewhere?

I hate it! I used a VPN to activate, turned off wifi, deinstalled vpn, installed netguard to disconnect every system app from the internet.

Is that even legal? They can't sell devices and force people to have internet... Especially without being honest to the customers while selling this..

I agree 💯

Your post reminded me to edit and create the video that I had shot 4 months ago when I noticed it on my unit.

So thank you for mentioning it.

It is disheartening to say the least.

And I'm very curious as to why they do that.
[Android Head-Units] nFiniti:
Its less restrictive on the UIS7862 Devices. You just use the 2nd Bluetooth in the Android System Settings menu, not the Joying BT App. Before I could use anything I wanted, Xbox Gaming Controller. Logitech Mouse and Keyboard, OBDx Pro VT, HPTuners, I've tried a few others from cheap OBD2 Devices and other no name bluetooth mouse. The loophole no longer works, The only thing that connects to the new Snapdragon Unit is my Samsung Galaxy S21. Xbox Gaming Controller and OBDX Pro VT show up in the search but doesn't connect, just sits there. If I go into System Settings and try to connect via the loophole method, it just sits there with a Waiting icon for hours upon hours. The BT Keyboard and mouse devices don't even show up when searching.

I prefer the UIS7862 devices right now. I have a couple and they work great. Especially with the @mariodantas mods. I'd kill to get him over https://xdaforums.com/t/custom-rom-...ng-qualcomm-snapdragon-665-headunits.4661801/ here to help with development on these new Snapdragon devices.

How did you connect the headunit to a Bluetooth device like your dash LED's because my Joying (2023 A12 snapdragon) will only connect to my phone & my OBDII dongle. No other Bluetooth devices will connect
