Maybe it is only me, went back from latest 20230306 to 20230207 FW, had some weird sounds from the radio when using my Sygic navi, on moment that Sygic makes notification, it should with navi mix put the radio a little down but the radio sounded really weird, like under water sounds.
Also had the impression that the antenna reception of the radio is a little worse.
All good again with downgrading to previous februari version, actually the first time I don't like an update.
I have the same experience. Problems with Sygic and worse radio reception. Returned to 230109.

Thanx:)

Do all the versions of this model S1 to S8 share the same apk/firmware?
Is this the original radio apk from our firmware that @Barykelo shared?, the one I uploaded earlier is the FM radio apk from our firmware. I looked inside it and it shows all the graphics from our radio app.

And yes firmware is the same for the s1 to s8 units.

There is one function in Teyes that is solved differently from the others. The processor has its own fan-cooled heat sink, and the case only cools the power amplifier screwed down and not in the pocket.
It seems that your model is such that the case is not standard, I looked at the Volkswagen, the exact same case is one to one and the exterior is no different, even without a fan they are sold, where the radiator on the processor I don’t know).

vendor confirmed software bug related to LOUDNESS, will be fixed in the new firmware
Explain normally what problems you have with the volume? I put all the updates and everything is fine, once I just had to disconnect from the network for a full reboot. Maybe I have problems with the volume, but I did not know)

From my observations:
The volume on our devices is not fully unified with the Android system volume, and for this reason, many third-party programs (not all) cannot control the volume.

I have an S7, I just wrote that Teyes did something for more efficient cooling for a higher price.

У мене S7, я тільки що написав, що Teyes зробив щось для більш ефективного охолодження за вищу ціну.
what does the name S7 have to do with this? You have a different device with a different case and, judging by the photo, even a circuit. What your manufacturer wrote has nothing to do with the system described in this article. I don't understand what all of you who bought Tiais are doing on this forum?)) People buy what suits them for the price, and here is your device? In any case, it's better to buy an average S4 device and an average power amplifier, then you won't need cooling at all, and the sound will be twice as clean and louder.People take this device because they consider it impractical to take something more expensive in a non-standard car. I agree with them.

I need help…

I bought the Hizpo S4. After the speakers didn't work with the normal speakers (sound only comes through the cinch outputs), the seller advised me to do a factory reset. Now I still have no sound via the speaker outputs and the soft-touch bar no longer works. No change even after updating the firmware and MCU (from Autofather.com). Does anyone have a solution?

After you do factory reset you loose all physical button control, canbus/factory and user settings, except for the home and return button on the screen.

Buttons you need to set again with going into carsettings app/factory 8888 ok.

You use canbus?, what car...

Speakers are going with my unit with the power plug to the car speakers....maybe you have a not compatible plug for your car?, wrongly wired for your car plug?
The pin configuration is shown on the Ebay page you shared.
If all checked and okay wired and not working....don't have a clue.

I have ours (Ossuret S7) and I'm on the right forum, and with this I replied to your statement that also Teyes are the same as most manufacturers. As you can see (photo added) they also do more for more money.

He shared the cooling and has a S7 himself, but agree that this thread is not to compare units and how wonderful they are compared to ours, my S8 not running hot, sounds great, deep bass, no crashes, so why spend extra money for solutions you don't need.
The biggest problem with heat is the dashboard itself, if heat stays inside there around the HU, no matter what cooling solution you have in the HU it will get warm...

What car do you have?
Maybe you have separate original amplifier? If so, try to unplug the battery for couple minute,

Thanks for Your answer. I've already looked under Carsetting / Factory with 8888, but I can't find the right menu item for setting the buttons.

I have a Volkswagen Transporter T4 and the radio does not work via CAN. Before that, a simple 1 DIN radio from Kenwood was installed.

The loudspeakers are connected via the ISO connector. It also works perfectly with the old radio. I have already tested this.

Amplifier and all speakers are no longer factory and have been retrofitted.

You talking about the home, return, volume up/down......right?
In my car I need to go to factorysetting (8888+ok) and then panel key study, no 3, select the key on the screen and then hold the physical/mechanical key/ button for few seconds on your unit...you get a green square, do all and save.

20230331_202912.jpg


But don't know your unit, if that are mechanical buttons or touch software buttons...

I cant remember the function of touch learning button, no.2,, but you can try both..I thought I used that in an earlier version of Firmware to make buttons works again, but in latest I used panel key study.

My unit is a S8 with Opel front that match my dashboard with mechanical buttons around it ..

About the ISO plug, check if the supplied one with the unit matches that, on your linked Ebay there is a wiring specification...of the plug you stick in your unit...so the wires on other side you put in your ISO plug must correspond to that, but imaging you know that already ...
I have totally different plug, don't know if the power cable they supplied is an ISO connector that matches yours .

Other then that I don't know....contact supplier again, maybe defected unit ..

Alot of cars today have built in amplifiers, loudness setting is sometimes an alias for canbus-controll of the amplifiers loudness setting.

And sometimes for the built in amps loudness setting, aka just use the damn dsp lol.

Late to the discussion, what exactly have you ordered? What harness was included? Are there any loose wires?

8888/2 worked for me. Big thanks for that!

I will check the speaker assignment on the device. I will report. If need be I will install an amplifier for the loudspeakers.

In any case, thanks so far for the help.

I have one last question. How can I reactivate the weather app?

    I appreciate your advice, but I didn't want to dismantle the radio from the car twice to position the thermopad...the left PCBs should all be the same, so the distance between the CPU and the case is the same.
    In your case this distance was 1.3mm and you used a 1.8mm thermopad, right?

    I don't understand why then another user wrote that the distance was 3mm (with S8 radio).

    Which is the right one
    Yes, i'm sure i was talked about it here, and also Aanton measured it and if I remember it was 1,6mm gap
    Look here and his previous posts

    I thought that solution was only if you have low sound capture...
    Both mic (interior and exterior) are in the same line, so if you have both, they interferr,
    1
    Thanks for the info.
    If the CPU to case gap is 1.6mm I think I will buy a 2mm thick thermopad, it should be fine too.
    What do you think?
    it depends on which thermopad you buy. the higher thermo conductivity, the pad are harder. So if you want 2mm thick, then buy no higher than 6W/mK. But IMO 1,8mm is ok.

    I am writing an answer to my question dedicated to specialists of this topic who do not know how the device works, but only write their guesses, and they confidently think that everyone is stupid!
    Changing the MCU version QF01 to the QF03 version is possible and very easy! Changing the version did not negatively affect my system in any way! The screen did not turn on from time to time and the seller himself told me to change the MCU, sent this version and told me how.
    To change the version of QF01 to QF03, you need to enter the code 774411 in the factory settings and then download a new MCU. The board version has nothing to do with the MCU ! As I understand it, there will be no more MCU 01 version

    Is there any advantage of using Android Auto or CarPlay on the Android HU if all apps you need are installed on HU and the HU has its own sim car with cell service?
    In my opinion there's absolutely NO advantage to use AA/CarPlay if you have 4G SIM with good signal coverage. You only get hotter HU being moooore busy running AA/CarPlay wich will also runs slower and also draining your phone battery for no reason.

    Later Edit: Also I see no advantage to use AA/CarPlay at all on Android HU, even with phone Hotspot is better if you don't have an 4G SIM or good coverage/speed!
    3
    AA only makes sense if you have an OEM multimedia system that is not based on Android. Conversely, with these units, it is of no use, all you need is a phone hotspot (or 4G SIM) and you can use the same apps directly, without AA .

    Naturally my opinion, perhaps not shared by others.

    Some features are better on Teyes than Sx.
    The CPUs are not the same, either.

    UI: they are all similar, true, but the graphics of a UI are subjective, I don't like the UIs of both Sx and Teyes, for example.

    A real IMPORTANT point for me is the display, in particular its sharpness, brightness and anti-glare, lasts the day, with direct sun.

    Well, with my S8 8GB\128GB as I have written here several times it is VERY BAD, very low brightness, during the day at 100% almost not readable what is running underneath. Anti-glare film does not exist...

    IF Teyes CC3 2K instead has a better screen, which you can see perfectly during the day, for me it would already be a great thing, even if it costs more than Sx units, but the problem...is all this true or does Teyes just want to advertise\marketing ?

    Anyone who sells advertises their product for sale even more than reality, to sell it...

    ONLY someone who has purchased and uses the latest Teyes CC3 2K units could truly say that!
    Now i'm waiting for cc3 2k, so when it comes, i'll say some more, compare to s8 unit which i use since february

    I have a QF03 never had a single issue with it. Have updated to latest firmware and have done 1 mcu update (1 more available not sure if I will install)
    Of course, MANY problems also arise from poor writing of the latest firmware and MCUs released by developers.

    My advice:
    If you have the unit that works well, don't chase constantly new firmware and MCUs, leave the working one as it is.

    Hello all,

    it seems that there are some QF001 owners out there but not much informations. So i will try to collect everything and put it at one place.

    The original manufactor is shenzhen jitu technology co. ltd.

    These units are sold from Ossuret, Hizpo and other brands. This are the sellers specs:
    specs.JPG


    The Android 12 is fake which is Android 10 in reality.

    I have the 8/128GB Version myself:
    Screenshot_20221129-085346.png


    Codes for the factory settings menu:

    Different firmware versions are inside this thread. Take care of the right MCU file and beware that clear user data is enabled by default on update. There is also a dedicated firmware thread: https://forum.xda-developers.com/t/...s-with-uis-7862a-7862s-not-fyt-based.4541261/

    Dedicated thread for gaining recovery access: https://forum.xda-developers.com/t/...uret-s4-s8-uis-7862-headunits-no-fyt.4538107/

    Beside the faked Android 12 Version the head unit seems to be a good bang for the buck. I´ve paid around 230 Euros including VAT and shipping. The unit runs stable and powerful so far. Everything works as expected. The Android is a bit downcutted by the manufactor. There are no text notifications in the statusbar e.g. But i can compensate that with widgets.

    Against the description android auto works wireless with my Xiaomi Mi10t pro. So that's also nice to have.

    Tweaks, mods and others:
    - my wire harness was labeled wrong. Key 2 and Key GND were swapped. So better check the cables before connecting. For me the correct wire names/functions were in the printed manual.

    - replacement fan that fits my model: Sunon MF35101V21000UA99

    - there's a sleep whitelist in the factory settings menu that prevents apps from being killed in standby mode (ignition off). That's very useful. I've whitelisted Google maps e.g. and don't lose my programmed route anymore if i turn off the engine for a short stop.

    - tasker trigger for warm boot: detect any USB device connected. (You have to plug in something into the usb port, dashcam or pendrive e.g.)

    - the status bar only shows a few symbols and no text notifications. Therefore I use a notification widget in combination with nova launcher. This way I can see all notifications in a widget which would be at the status bar originally.

    - wireless ADB is enabled by default with root user. 🎉 The port is 9876. ( I've found that inside the build.prop)

    - if you want to have a look inside the firmware you can use a rom kitchen tool like CBR

    - how to change the boot logo:
    1. If your player is 1280*720 screen, you need to rotate the picture 90 degree, and cut it into 720*1280 size, transform the picture to .BMP format.
    2. If your player is 1024*600 screen, you need to cut the picture to 1024*600 size, transform the picture to .BMP format.
    3. copy the picture into your Udisk root path, and then connect Udisk to the player. follow the steps settings-factory-8888-Logo set-then you can see your picture and select it- click update logo.
    - how to change boot animation: https://forum.xda-developers.com/t/...uis-7862s-not-fyt-based.4525675/post-88086835

    - enhance the microphone and call quality by using the external microphone and disable the internal microphone by masking two pins of a ribbon cable. It's explained inside this thread (link to post will follow)

    - GPS tweak: https://forum.xda-developers.com/t/...uis-7862s-not-fyt-based.4525675/post-88112693

    Known issues:
    - "hey Google" (activate the assistant by hotword) doesn't work
    - no car speed dependent volume control (manufacturer says it would be implemented later)
    - the firmware is a debug release which is a serious security risk (every app or malware can get root access through ADB shell). On the upside you can also get root access through ADB and do everything you want

    To be continued...

    Cheers

    Hi all, if anybody would like to test a very early alpha version of NavRadio(basic), they can find it here:
    Download NavRadio BASIC for QF01

    it's incomplete, full of bugs, it surely crash here and there but still usable.
    I have enabled Google Crashlytics to help me debug all the crash and ANR so more people use it and more i'll fix it.

    The full version will come when the free version will run smootly.
    Enjoy;)


    NOTES:

    - Autoscan is done by MCU and it's fixed to 18 stations. Anyway you can use Autoseek function to find more stations or add new ones to the existing ones.
    - The first frequency at startup need to be fixed.
    - Sometimes you can hear the sound muting for a second, it's because the ROCO service think that navradio is a player and not a radio. I'll look for a fix later on..
    10
    And now a few more!

    1122 / 2211 - both popup a bubble with chinese text. I thought they were the same at first but they have different characters. (They both have the word “log” in it)

    6655 - opens up a screen that appears to be the same as 555666 but these are also in Chinese so I don’t know if there are differences. Notably when you enter this menu with either code it will record a snippet of audio from the mic and play it back.

    4455 - engineer mode (lots of stuff in here to explore, includes adb shell)

    5544 - gps stuff

    1212 - notification that says “slog copied to unkown”

    2121 - seems to just take you home

    45645600 - download mcu file

    How did you discover the codes?
    Just by trying a bunch of different codes and looking for patterns. Starting by looking at the codes we already knew I discovered they are all a repeating sequence of digits that are adjacent to each other on the keypad. Once you find a pattern there’s usually another code that uses the same pattern somewhere else on the keypad. If you actually type in the codes and look at the physical pattern they make you’ll see what I mean. For example 114477 is just the digits in the left column of the keypad going down. 336699 is the same pattern in the right column. And then some codes are just variations on top of that, like doing a code in reverse (which we already knew) as well as adding 00 to the end of some. This is how I discovered all the codes. Once I’d find one code Id try that same pattern in all places and variations. Simple as that! I’m sure there’s more patterns yet to be discovered so try different ideas out and see what you can find. With many people using these strategies I’m sure we can discover more! I may have even missed a few using the patterns of ones I found.

    For whom that's interested and is annoyed that display time is out of sync with atomic network clock time.

    Myself don't use 4G network, but WIFI hotspot from phone.

    Each time when I opened the GPS test app, time changed and was out of sync by 2 to 4 minutes, also when I forgot to put hotspot on my phone on, after that it was taken the GPS time sync by default after startup,
    So first taken my right hotspot network time and changed 30 seconds later to the out of sync GPS time, it was also out of sync with my OEM Opel board computer display.
    With some hassle I could changed that back but needed to be sure that hotspot was always on before starting the car.

    Think I found a solution.

    Note, I don't use sleep mode, always have a fresh cold start, unit starts up with firmware date and time, 09-01-2023, 12:05:54.

    After going in the factory 5544 GPS setting, changed on first tab screen "agps" the server SUPL host to supl.google.com, changed port to 7276 (seems secure port), but you also can leave it on 7275, then tab screen "information", on the bottom page changed the satellites to GPS, Glonass, Galileo, my problem disappeared.

    My unit correctly shows the time now, after a start-up it is in sync within 1 second compared to atomic clock, with or without hotspot, mean also without network connection it syncs with GPS satellites the time correct.
    The AGPS SUPL was using the Chinese host (supl.qxwz.com) and preferred what it looks some Chinese satellites for Glonass and Galileo and somehow the Chinese GPS time is inaccurate.

    Rather Google then the Chinese that follows me ;)
