DUDUOS 3.8: Elevate Your Drive - Public Beta Rolling Out 260930

YAOXILONG

🚀 DUDUOS 3.8 Public Beta is Officially Here! 🎉✨

The next evolution of your smart driving experience has arrived. We are thrilled to kick off the DUDUOS 3.8 Public Beta!

⚠️ Important Notice for Testers:

This is a Public Beta build intended for enthusiasts and advanced users who enjoy exploring early features and helping test new implementations. If you rely on absolute day-to-day stability, we recommend waiting for the official stable release.

As this is the very first public beta release with significant architectural updates and potential edge cases, OTA updates are not supported for this build. Please perform an offline update using a USB flash drive.

A heartfelt THANK YOU to our amazing community! Without our early alpha/closed beta testers who reported bugs around the clock, and our dedicated translators on Weblate who brought every new string to global drivers, this massive milestone would not have been possible. You truly shape the future of DUDUAUTO. ❤️✍️

🔧 What's New in DUDUOS 3.8

All-New DUDU Launcher with Smart Driving Mode

A redesigned dashboard layout optimized for seamless navigation and vehicle monitoring, now featuring in-depth climate control integration.

Quick Launcher Mode Switcher

Launcher layouts can now be switched directly via the Mode Switcher app icon, without digging into the system settings menus.

Customizable Navigation Bar

Personalize your dock layout with drag-and-drop widget arrangement: long-press to edit and freely rearrange the dock modules.

Advanced Vehicle Status Bar

Displays real-time factory telemetry across layouts, with expanded factory vehicle data coverage; long-press to customize which indicators are shown. (Note: Supported across all interface modes except Borderless/Unbounded mode, Audiophile/Enthusiast mode, and vertical/portrait screens).

Portrait Screen Card Mode

Introduces a dedicated card-based UI layout optimized for portrait/vertical displays to enhance vertical interaction ergonomics. (Image placeholder)

360° Vision System & ADAS Integration

Brand-new panoramic camera app featuring a 6-way surround view and built-in intelligent ADAS warnings. Enable ADAS warnings under 360 Settings ➔ Vehicle Settings ➔ Enable ADAS (7870 platform).

The 6-way blind-spot 360 view requires the additional blind-spot cameras to be installed to give you far better visibility of your blind spots, then switch to 6-way mode in Factory Settings. Only the 7870 platform is supported, and the matching accessory kit will be released at a later date.

How to switch to the new 360 app: If your unit is still using the legacy 360 app, go to Settings ➔ Vehicle ➔ Factory Settings (PIN: 108) ➔ Other Settings to enable the new 360 view.

(Important: Before switching versions, we strongly recommend exporting your existing camera calibration and stitching data to an external USB drive. After switching to the new 360 app, recalibrating/re-stitching is recommended to achieve optimal camera alignment and visual performance).

360 Tuning & Backup

Camera angle parameters are now included in system backups, with numerical readouts for precise fine-tuning of the camera alignment. (Image placeholder)

Speed-Triggered 360 Views

360 turn-signal activation now supports speed threshold triggers, and 6-way mode switches perspectives based on vehicle speed. (Image placeholder)

Carlink Enhancements (HD/FHD & Multi-Touch)

Added HD / FHD resolution switching specifically for Android Auto, and resolved the Android Auto audio mixing bug.

Apple CarPlay now supports two-finger multi-touch gestures (requires iOS 26 or above).

When using left or right side navigation bars, the dock now automatically collapses during active CarPlay/Android Auto sessions to ensure optimal full-screen projection.

Independent Driver-Side Audio Routing

The navigation voice prompts and Bluetooth phone calls can now be independently routed to output exclusively through the driver-side speaker. (The navi prompts only on DUDU7 hardware powered by the AKM7739 DSP.) Navigation audio: Sound Settings ➔ Mixing Settings ➔ Navigation Mixing.

The Bluetooth phone calls can now be independently routed to output exclusively through the driver-side speaker. Bluetooth phone audio: More Features ➔ Bluetooth Phone.

Ignition Sleep Password Lock

Custom Per-Window PiP DPI

Adjust display density independently for Picture-in-Picture floating windows.

PiP Performance Optimization

Refactored the Picture-in-Picture rendering architecture to improve PiP frame rates and prevent black-screen glitches. (Image placeholder)

Background Keep-Alive Management

Configure persistent background apps under Startup Settings ➔ Sleep Keep-Alive to prevent critical background processes from being suspended.

DVR App Upgraded to 2.0

Now supports Gen 2 and Gen 3 dashcams. ADAS adds smart detection for pedestrians and non-motorized vehicles, with expanded compatibility for newer Android versions (including Android 14 on the 7865 platform).

YAOXILONG this beta includes translation update fixed at which date? thx

hafiz_tahir

YAOXILONG great job. Will try to install it.
1 dissapointment and it still happen during 3.8, which is inclusivity of non 7870 device to adopt some new feature. Since the device (DUDU6) still actively sold in market, developer should consider include the features and make it available to DUDU6. Unless the device has been stop distributed and consider end if support.

hafiz_tahir

YAOXILONG @DUDU-Meng for the adas 2nd generation, do i need to update my dvr 2k apps? I check for update and no latest version available

DahTank

YAOXILONG YES!

Been waiting for this to install my Sony 662 360 cams

Bladesore

Yaaay!

"When using left or right side navigation bars, the dock now automatically collapses during active CarPlay/Android Auto sessions to ensure optimal full-screen projection."

Please add this as a toggle for the bottom bar too! I remember this was possible back in 3.5. Currently, in order to experience CarPlay in full screen we have to force close the app, manually hiding the bottom bar and then opening CarLink again. Not doing this results in a letterboxed UI.

Oto

I’ve been waiting for this! 🎉 With the 3.8 beta, should we retest the issues we had before and reassess them from scratch?

Blackbandt

Very nice. I'll take a look at that tomorrow, German time. Does anyone know if phase reversal has been added for the subwoofer?

Michael221097

when it install does the ota work to get new beta build when they come out or do we have contact dev ?

Fastback

Michael221097 You have to contact them. Betas don't work over OTA

Fastback

All cool, but I assume that the bugs where optical audio breaks after fast boot, and fast boot generally frequently not working at all, aren't fixed yet. I reported them a month ago; with the latest beta from a week ago, there has been no response.

Intelligent Mode Launcher: is just copy & paste "Borderless Mode" with AC settings on the left. I don't understand what's intelligent about it
Quick Launcher Mode Switcher: What is the point of it? Is there literally anyone who switches launchers frequently?? That just seems like a way for you to make development easy, and not actually something that benefits the end user. Whatever, it shouldn't be listed on the top of your changes.
Customizable Navigation Bar: Nice change, although the change's name is just misleading. It's nothing more than just a UI enhancement, and there's nothing new configurable

Other changes seem to be good, although there should be WAY more bug fixes. All those nice features are useless if your device is generally unbearable to use

Timothy

Hi, these features are actually useful and I don't know why you're complaining when they could just not update anything at all? Be glad there is a team that is going through bugs and enhancements, it's better than nothing. I've had no issues with their updates and this time around they seem to have done a lot of improvements, not just with the UI, but specifically with back end stuff like audio, which is already great to begin with. Let's not jump to conclusions that they aren't listening, but instead be glad they are doing anything at all. Create your own UI and you can do whatever you want to it, but if you can't, then you must request features and wait for them to see if the majority of users want something. They aren't your personal developers, they are running a company, please be patient and be mindful of their work. If they aren't responding, it's probably not an urgent message such as a device failing. Request are requests, not checklists or demands. They are doing more work than any other radio companies out there right now. So let's be kind and move forward together, thank you.

hafiz_tahir

Fastback i do use these features, so i think this is useful. Its more like iffering flexibility rather than fixed the UI setup. If you didnt use it, just leave it there.

Fastback

Timothy Okay? Am I not allowed to complain? And what can I do with those nice new and shiny features if I can't use the device at all?!

They aren't your personal developers, they are running a company, please be patient and be mindful of their work
please be patient and be mindful of their work.

Next level dick riding. Bro I payed 700€ for a device that does NOT work. A radio that does not play sound or music is not a radio. And a radio for which I have to wait a minute to boot every time I start the car is a shitty one on top.

Timothy

Hello, great work with the new update, I've already noticed the improvements with everything! I especially like that I can finally pinch to zoom on carplay. As well as putting navigation audio through the driver door. The only thing I found to be an annoyance (at least for my dual knob screen) is when using the dock volume configuration, the side volume slider still appears too. Not sure if there is a way to turn it off or not, but it would be nice to just have the dock slider so it helps clear up screen space when adjusting volume. Otherwise, awesome job dudu team!

Timothy

Fastback

If my device wasn't working, I'd be contacting support to get a refund or get some sort of assistance like a replacement. If you aren't able to use the device, you should be contacting the seller and not just devs on a forum post. Like it's not that hard. My dudu 7 has had no issues and have had a great experience with the seller. I personally bought from mekede and they have been wonderful. Wrong channel to be cussing people out about a personal issue you're having with your device, whether it's with how you installed it, or settings you configured wrong. Seems like a skill issue

Fastback

hafiz_tahir At what exact point did I say they are bad and that you shouldn't use them? If you like them, good for you. Doesn't change the fact that it's not a good sign if the forum is literally filled with bug reports, them ignoring the bug reports, and rather focus on new features, which will just be a burden on the device's already poor stability on top.

hafiz_tahir

Fastback i do expeirence bug and i reported here, they act on it and produce bugfix. only sometime, they are shorthanded, the respond will be delayed, but they will produce the bugfix

Fastback

Timothy I'd be contacting support to get a refund

I did that

Timothy get some sort of assistance like a replacement

I did that

Timothy you should be contacting the seller and not just devs on a forum post

It's not a hardware issue, it's a software issue

Timothy whether it's with how you installed it

I did not install anything. It's an original product.

Timothy settings you configured wrong

Do you know or are you assuming at this point? Because I highly doubt there is any config that tells hibernate or optical audio to break every few times. And didn't you just say it's a defect hardware, since you told me to contact my seller? That's kinda contrary.

Timothy Like it's not that hard

Timothy Seems like a skill issue

Absolute rage baiting at this point. Just mind your own business if you don't know what you are talking about and have absolutely nothing to add. Thank you. I just want a working device, and for 700€ that is not too much to ask, especially since I could've just gone with Joying or just stay with my OEM and have a better experience.

And like, why are you protecting them so much? Do you think they care about you? Do you love them? Jesus christ, these people. Find people to love and not some random Chinese Company

Timothy

Fastback

I don't use optical so I can't speak for that, but again, it sounds like a very specific problem you're facing, I wish you the best of luck
