Hi. I have a Mekede M400 radio and I have installed DuDu OS ver 3.5. Since I bought this radio, I have been having problems with accidental restarts and system freezes. Here are my radio data and logs from the ''crasch'' directory.

    PolJet Don't want to be mean. But please check the "How to give feedback on bugs" thread. The photo you provided is almost for no help. And it would be much better for the devs to provide the files from the crash folder not to copy the text from those files.
    Anyway you'll have to wait for the new year holiday in China to be finished to get an answer. Do you use a sim card on your unit?

      Is it DUDU7/6? DUDUOS System crash or radio crash reboot.
      Do you have more detailed logs? Is there a video recording of the reboot issue?

        Attached is a photo of the currently installed system. The radio is Mekede m400 with uis 8581 processor. The current system is DuDuOs 3.6

        Below I am adding two logs that I found in the crash folder:

        I have more logs, but they are quite large, how can I send them? It would be best if I sent them by e-mail.

        I still have logs:
        bugreport
        events
        grtprop
        main
        radio
        ro.build.fingerprint
        system

            PolJet Please understand not to copy the text. These logs are .txt files. You can easily upload the .txt files to your post. Please help the devs so they can help you.

              Please send us all TXT files.

                  I have some similar problems. But for me is it my DUDU7.
                  When i connect the OBD olug that goes to the canbus box, then the head unit reboots.
                  I think it is because the raddoes not know what to to with signals coming from the canbus because there still is no implementation of Suzuki Vitara LY Boosterjet Mild Hybrid canbus data.

                      This log is due to issues with DuduAuto Pro.
                      Where do you encounter problems while using the device, such as getting stuck in the homepage or settings.

                          mrqasq i also have this with CANBUS on Honda Accord VIII 2010.

                            caolz I have problems with the fact that at various random times the radio resets and starts again from the Android logo. I don't use many applications, I also have navradio, sygic, musicolet and all these applications. Generally, after a few system updates, the biggest problem is restarting the system. The applications work correctly, but even when the system is running and I do nothing, I do not touch the screen, I do not increase the volume, I do not switch applications, etc., the radio turns itself off and restarts the system. However, this is not a restart from the initial settings, but a restart with the system settings.

                                mrqasq ten can bus nie wydaje się stwarzać problemów, ale nie jestem znawcą. Jak wpisałem do Open AI parę logów ,to ogólnie chodziło o problemy z ''jawą'' , skalowaniem okienek, program odnoszą się do ''urządzeń '' których nie ma lub nie można ich odnaleźć. To tak z grubsza.
