DUDUOS Beta Testing Expands to More Devices! Join Now for Portrait Mode Support!

YAOXILONG

Dear DUDUAUTO Community,

We are thrilled to announce that DUDUOS 3.7beta has been optimized for small screens (8 inches and below) and now features a vertical layout, as well as added UI support for dual-knob screen devices! We are now accepting applications for Beta testing and invite users with these compatible devices to participate. 🔧🆕

Official DUDUAUTO DUDU3_DUDU7 devices come pre-installed with genuine DUDUOS systems. We extend our sincere gratitude to all users who have purchased DUDUAUTO devices. 💯✅

Here's an overview of the DUDUOS International Beta Testing Program and registration process.

The DUDUOS International Beta Testing Program is completely free and open to users outside mainland China (in mainland China, we have an authorized distributor, DUDU Liangshan). The program supports most generic FYT7862 and FYT8581 devices (only FYT solutions are supported; TOPWAY and other solutions using the same processor are not supported). Generic FYT7870 head units are not supported. Users who meet the requirements and pass the application review can use DUDUOS permanently for free. 🌐🆓

After registering a DUDU ID in DUDUOS, you can enjoy a 6-month free trial of Internet value-added services. During this period, you can access features such as trip records, cloud backup settings, and unlimited daily theme downloads for the international version. Please note that there are currently no paid subscription channels available. We are continuously expanding features and developing mobile applications, and these value-added services will be launched in the future. 🎁🌟

All basic functions of DUDUOS are free, and the end of the free trial period will not affect your use of the system. Early testers may find that their free trial period has already ended. 📅💫

Rest assured, DUDUOS will not adopt a paid registration model. The Beta Testing Program will eventually end, but this will not affect registered devices. 🔒💸

Are passionate about in-vehicle infotainment systems 🚗💡

Actively participate in group and forum discussions 🗣💬

YAOXILONG is there some changes in this beta file? If so can you please highlight them and perhaps share some pictures of that here?

Your team should work on sound settings:

Feature / Improvement Requests for DUDU7 Firmware

HPF / LPF Adjustment Buttons
- Add + / – buttons for High-Pass and Low-Pass filter frequency adjustment (in addition to slider). With HPF values, I can't set precisely 80Hz, it's either 77hz or 82hz nothing in between.
- Display filter slope graph visually during adjustment (as already shown in standard FYT7870 DSP UI).
Subwoofer Phase Control
- Add Subwoofer Phase setting adjustable from 0° to 180° (or continuously variable).
- This helps match subwoofer phase alignment with front stage.
Separate EQ for Front and Rear Channels
- Allow independent EQ control for Front and Rear speakers.
- This is important when rear speakers have different tweeter response or are used for fill.
Surround Focus / Time Alignment Preset Handling
- Add 2–3 user-saveable presets for Surround Focus / Independent speaker delay settings.
- Fix behavior where Independent mode values reset when switching to Linkage and back. The system should retain previous manual values.
DTS Default Setting
- Set DTS to OFF by default. Currently it is defaults to ON which affects tonality.

The hardware is more than capable for this, AKM7739 even support per channel EQ. 3.7 update should include these changes.

YAOXILONG how I can do to test this os , I have one Ainavi ts18 ?

YAOXILONG Reg 7862. I’m running into a recurring wireless Android Auto problem. It seems the CarLink app starts and then quits when the launcher launches during boot, which breaks Android Auto when I later open CarLink. I’ve had to turn off CarLink’s auto‑start on Bluetooth connection and launch it manually after the launcher is fully up. Is there a way to keep Bluetooth disabled at boot and only enable it once the launcher has started? Also post to Bluetooth on can't we run if Bluetooth not connected toggle Bluetooth on off using shell?

It's a shame it's only for 8-inch and smaller displays. When will the beta version for other displays be released? 10 inches and up?

YAOXILONG

Blackbandt

Thank you for your question regarding the DUDUOS Beta Testing Program.

To clarify, the DUDUOS Beta Testing Program has always supported devices with screens larger than 8 inches. The recent announcement about DUDUOS 3.7beta specifically highlights new optimizations for small screens (8 inches and below), including a vertical layout and UI support for dual-knob screen devices. This is an expansion of our compatibility, not a reduction.

Our program continues to support eligible devices with various screen sizes, and the core testing program remains unchanged for larger displays.

If you have a compatible FYT device and meet the other criteria outlined in the announcement, we encourage you to apply for the Beta Testing Program following the registration steps provided.

YAOXILONG Ah, I see. I own a Dudu7 with 8+128 and a 10-inch display. So I can register for the beta and test it if necessary, right?

YAOXILONG

Blackbandt Thank you for purchasing DUDUAUTO device, the DUDU7 does not need to register a test plan, it comes with the original DUDUOS and has more powerful hardware and audio, you can upgrade the test version of the system manually at any time if you want to experience it.

Blackbandt здравствуйте

YAOXILONG

YAOXILONG hello ai have one Ainavi ts18 , I was bale to install Dudu launcher , but still don’t have the options , for control doors , lights , and my canbus is working with my original system , but not with Dudu launcher , how I can make this work , I need special permissions, pay subscription?

Blackbandt

@YAOXILONG I have a DUDU7. Is it correct that I need the following beta update file: DUDUOS 3.7b for 7870 v251104?

And if it's the 7870 beta file, does it also work with the 10-inch display? Or is it only for the smaller displays for now?

I'd rather ask again to be on the safe side. I don't want to break anything and my 10-inch Dudu7 no longer works.

Blackbandt This is what I have just used on mine and worked fine. Check the Android about info and your number should be in the CPU info.

I connect the rear monitor rca to the dudu7 and listen to the sound through the speaker.
I listen to it through aux, but the aux volume is much lower than that of ordinary music.

Hello, @YAOXILONG , and big congrats for you and your team on the constant work that you guys put into Dudu products and OS.

I have a Dudu7 10 inch device that I want to converts to a vertical screen. I would also be happy to flash the 3.7b version afterwards. Do you have any advices on how I can get my hands on a vertical screen that is compatible with dudu7 headunit display module?

Blackbandt
