    A mi lo de los reinicios me viene pasando con los dos últimos modelos de radio android que he tenido, ahora estoy esperando que me llegue el didu 7, descubrí el problema, la aplicación que provocaba los reinicios era Agama car launcher, desde que la desinstalé no ha dado problemas, rn mi caso los reinicios eran muy escandalosos, por que al tener un amplificador externo ese punch que hace al reiniciar suena muy fuerte y parece un cortocircuito, daba miedo conducir así.

    I am having the exact same issue recently after upgrading to OS 3.5. It reboots randomly when I am driving or its stationary. First i though its Youtube. then I thought it's DVR2k . Now it just happened with carplay only as well. There is no pattern. Just that it reboots and fans spin full speed and everything comes back up just to again reboot sometime later randomly. I have 8 GB 256 GB model with 11.5 Inch display and everything was fanstastic before this reboot. Can't be loose cable as it happens even when stationary.

    MihaiFlorin i’m using the dudu2k Camera , I’ve already tried unplugging it still the same, just random shutdowns and reboots. Today I factory restored the head unit now the canbus works great, And the unit worked for a good hour and a half Before it rebooted

      dudu-lai I finally received a new harness, checked all the wiring added an extra ground wire and it’s still reboot. Do I have a defective unit?

        dudu-lai

        These are the steps I took:

        • I got a new harness and installed the head unit with an extra ground wire attached to the wiring harness
        • I also checked the ACC wire and the constant wire just to make sure everything is fine.
        • Factory reset the unit
        • I replace the old DVR camera with dudu 2k camera updated all the basic apps
        • I'm currently on dudu 3.5

        I still get a random reboot out of nowhere can you please help?
        I i will send you the link to my google drive with the corresponding txt. and ylog files.

            Is there a boot animation for every random reboot?

              Mongcharlie No reboot-related Android logs were found in the logs, but the15:55 PM OG loss, lots of USB errors in the kernel
              What devices are connected to the radio's 3 USB ports?

                  dudu-lai

                  yes
                  like a complete shutdown
                  completely off and turns back on immediately
                  like the picture you sent

                  What devices are connected to the radio's 3 USB ports?
                  : dudu tpms
                  : dudu 2k cam
                  : the last one is connected to the cars factory usb a connector for charging

                  I also have a data sim connected too

                  thanks for helping i've been dealing with this issue since i got the head unit

                      Mongcharlie The engineers want you to unplug all 3 USB connectors on the back of the radio to test if the radio will randomly reboot.
                      If the method does not work, print the ylog log again with all 3 USB connectors unplugged. Because this time, the logs sent to us have a large number of USB error reports

                          dudu-lai ok I'll do that and report back thank you

                            dudu-lai
                            I read somewhere that a bad SD card might have an effect on the camera and cause it to reboot the head unit is this possible

                                Mongcharlie Yes. I had this kind of problems because a bad USB drive

                                    MihaiFlorin i'll get a new micro SD today too to try it out

                                      Hi, I have a DUDU7 11.5 with 12GB/512GB unit installed a few weeks ago and updated to 3.5. It was working well last few weeks until last weekend when I was doing very long drives for several hours at a time and noticed that it would turn off and then reboot (with the Google boot animation) at random times for no apparent reason. It did it 3-4 times during the day, that I noticed.

                                      I normally don't have any USB devices plugged into the unit, except for 1 to charge a GPS tracker (power only, no data). This last weekend I did have my phone plugged in to charge a couple of times. And now I come to think of it, I think the random reboots occurred while I had the phone plugged in.

                                      Later that day I drove back home 3-4 hours and the phone was unplugged and no reboots at all.

                                      Could this point to the USB errors that could be causing reboots?

                                        TimF Yes, check the cell phone charging cable and the radio USB cable

                                            dudu-lai

                                            This is the latest occurrence of the rebooting.
                                            the DUDU TPSM was only thing that connected this happened before 10am vietnam time march 1st

                                            here is the link to the report

                                            rebooted again mar 1st around 8pm

                                                Mongcharlie Is only the TPMS USB receiver connected? Are other USB ports not connected?

                                                    dudu-lai

                                                    I label the folders on google drive
                                                    one folder has the ylog of the reboot with just the tpms connected (happened in the morning)
                                                    the other folder happened last night, (nothing connected to the USB)

                                                    is it possible to go back to the last stable version? maybe os 3.0 ? the reboots are inconvenient

                                                    TIA

                                                        Mongcharlie I'll submit the logs to the engineer when he gets to work tomorrow, Monday, and if he doesn't have a good idea, I'll tell you how to get back to OS 3.0.
