  • DUDU Launcher Global Updated & Download

Hello, when I try installing it I receive the error "App not installed as package conflicts with an existing package."

How do I resolve this so I can install it?

This is on a CHSTEK 7862 system, installing the public version. I am aware of other owners of the same device who have been able to install the DUDU launcher from this site.

Thank you.

    Hello. Happy Chinese New Year!
    Can you provide dudu launcher version with public signature for Changan cs75plus please? Last one gives an error: "Package has no signatures that match those in shared user android.uid.system."

    I need the PIP version. Thank you in advance!

        What is the advantage of using the Dudu OS on my unit instead of just this launcher? I've tried the launcher and it works well.

          Does this launcher work on FYT 7862s Android 12 (SP1A)? The launcher with two PiP on home screen?

            abidali I don't think it will work on Android 12 7862. It has its own private signature, which doesn't match with the public signature with Android test key like Android 10 version of 7862.

              Rev Would be interested in this too. I have held installing DuduOS because my HU only has 2GB RAM, which is below the recommended spec. But so far Dudu Launcher is working quite nicely despite the limited RAM

                  Hello, I have a Lelong Le-6321 multimedia device, but I can't install this version 1.013003 of the Public Signature, could someone help me with this?

                  @YAOXILONG

                    jjsabadini If the Public signature doesn't work, try with the private signature version

                      YAOXILONG Sorry for the late reply but I wanted to make sure the launcher installed had PIP. I try to ensure the PIP maps is available but doesn't seem to be on the one that installs.

                        PIP works on android versions 9 or 10. PIP is not available on android 12 and higher. Is it possible to upgrade the android version in the application so that PIP becomes available on android 12 and higher?

                          Public Signature version or Private Signature version or Qualcomm Signature version

                            phandinh8999 I would say try the Qualcomm first, then the Private version. The Public one definitely won't work on your HU unfortunately

                                Добрый день , скажите пожалуйста , можно ли какую то версию с PiP установить на ГУ Changan CS 35 plus new ? Quadcore t7 , 2gb RAM?

                                Hello,
                                This launcher seems to be magnificent, and I would like to try it out on the Android Head unit of my Mercedes, which is a snapdragon 685 with Android 13.
                                Yesterday tried to install both the public and the qualcomm version but no success as it gives the messages "the signature conflict with an existing one" or something similar.
                                Can you help me with this please?
                                Thank you in advance.
                                Kind regards,

                                irst of all, I would like to thank the entire Dudu team for this amazing application. If I had known about Dudu earlier, I would have bought a DuduAuto head unit. Unfortunately, I bought an Ainavi H5 head unit for my Clio 4.

                                So my question is: would it be possible to change the firmware of my head unit to the Dudu firmware?

                                If not, I have tested the launchers available with the latest updates (I am running Android 13 and I know that the signed version does not install). For the unsigned and Qualcomm versions, they work, but I have two issues:
                                1. For the unsigned version, the missing PIP (Picture-in-Picture) feature is a problem. This version is very stable, but the lack of PIP hinders my daily use. Will there be an updated version with PIP support?
                                2. For the Qualcomm version, it is a bit less stable, but all the features are present. The only issue is the language selection, which remains in English even after choosing another language. Although it’s not a major issue, I wanted to point it out (maybe for a future fix).

                                Regarding the signed version, I cannot install it, so I am wondering what the actual difference is between the signed and unsigned versions. And if the signed version is more stable, how could I install it on my head unit?

                                To sum up, my first choice would be to have the Dudu OS firmware on my head unit instead of the current one, if possible. If not, what is the difference between the signed and unsigned versions? And if the signed version is more stable, how can I install it?
