I've noticed the display on my OnePlus 9 flickers slightly as the display refresh rate adjusts from 60hz to 120hz and vice versa. Turning high 120 refresh rate off prevents the issue. It is more noticeable with dark mode activated.

Furtheremore they are color difference in screen like this video of exemple :

This is so annoying !
[OnePlus 9] blackhawk:
Don't know if that's normal or not, but all the variable rate displays have more glitches than their fixed rate display AMOLED counerparts in general.

Your phone is one of the best variable rate displays out there.

Try a hard reboot, clear system cache and also try in safe mode to rule out a 3rd party app bug.

Disable all power management... destroyer of worlds. Developer options>standby apps, all buckets should show as active otherwise power management is active.

Factory reset, last resort.

It may be a firmware bug present in all. Lastly it could be hardware especially if not many others are seeing this behavior.

That kind of glitch would drive me nuts. Poorer color rendering on the new variable rate Samsung's as well as almost all of the other brands is one reason I bought a second new Note 10+. I'll eat the 60hz notchiness for peace of mind.

Factory setup/calibration of the variable rate displays is extremely difficult and not perfected as of yet. As I said your phone should be one of the best variable rate displays... be glad it's not one of the others.
[OnePlus 9] avid_droid:
That's a OnePlus 9? Center hole punch? Hmmm. With smooth display option from 60-90hz? Never seen that model.......
[OnePlus 9] AndroidsKings:
That's a sample video to show what my 9 does.

Oh hahaha.

This thread is consolidating all the information of Junsun V1 and V1Pro devices scattered in the Android Head-Units forum. I want to write and extend this to make it easier for new people. It's sometimes difficult to find the right information.

Warning: Some of these commands are altering the system. If something goes wrong you can brick your device. Be sure you know what you're doing. I'm not responsible for any damages!

[Android Head-Units] mopfi:
Updating Firmware​

Preparation​

USB drive formatted as FAT32

Files for update (*.bin, *.upd) need to be in the root directory of the USB drive

Starting the Update​

The update should start automatically when the USB drive is plugged in. A pop-up appears that says that an update will start. After a few seconds the device will reboot and install the update.

If this doesn't work, plug in the USB stick and restart the device with a needle in the reset button. When the device starts up move one finger on the touchscreen around and wait for a green detected message at the top of the screen. The update will start.

Problem solving​

I don't have a *.upd file

That is OK, the file does mot contain any information. Just create a new empty file and rename it like the *.bin file. As example, if you have a 8259.bin create a 8259.upd file.

The device doesn't recognize my USB thumb drive

There are 2 USB connectors on the back of the device. If one does not work, try the other. Make sure your thumb drive is formatted as FAT32.

Firmware Files​

This list is made by taking links from different firmware threads (found in first post). Every entry has a link to the original posts. Please be careful when flashing, the files need to match the correct CPU and screen resolution. If you have files for the normal V1 or different screen resolutions you can send me a PM.

Factory Reset​

Settings -> Car Infotainment -> About Device -> Settings Icon -> Code 8878 -> Erase all Content
[Android Head-Units] mopfi:
ADB Connection​

Preparation​

Activate Developer options. You have to click a few times on the build number until you are a developer: Settings -> System -> About Car -> Build number

Activate USB debugging. Settings -> System -> Developer options -> USB debugging

Use the 4-pin USB connection on the back of the device. Connect with a USB A <-> USB A cable. My device had a female Mini USB adapter for using a Mini USB cable.

Connect​

Use adb to connect to the device

adb shell

Problem solving​

ADB can't find any devices

It could be that the ADB connection with the device is not working. This means that the corresponding option is not set. This can be done temporary or permanent.

Temporary Connection

To make the connection with adb work temporary we can change the USB setting of the device. To do that we need to set Settings -> USB Preferences -> USB controlled by -> This device. No it should be possible to connect via ADB. The connection is temporary, because after a reboot it is gone and has to be set again.​

Permanent Connection

We can enable the connection permanently by changing a value in the secret menu. Go to Settings -> About Device -> Cogwheel (top right) -> Code 8878 -> Others -> USB2 Debug -> Enable​

Can't find USB Preferences

Go to Settings and click the search icon in top right corner. Type in usb and then click USB controlled by.
[Android Head-Units] mopfi:
Root​

Create boot.img​

Connect via adb to the device and find the location of the boot partition. The star '*' has to be replaced according to your device. For my Junsun V1Pro it is bootdevice. In the next step we will create a copy of the boot partition. Please be careful with dd command. It will overwrite wrong files or partitions if you do a mistake.

adb shell
su @#zxcvbnmasdfghjklqwertyuiop1234567890,.
ls -l /dev/block/platform/*/by-name/
dd if=/dev/block/platform/*/by-name/boot of=/sdcard/boot.img

Patch boot.img​

Install Magisk apk on your device. I used Magisk v23.0 from here: https://github.com/topjohnwu/Magisk

Open the app and click on top right Install button

Then click next and choose Select and Patch File

Select your boot.img and let Magisk patch it.

Copy the new created file to your computer. The filename will be similar to magisk_patched_23000_***_boot.img

adb pull /sdcard/magisk_patched_boot.img <older_on_your_computer>

Flash magisk_patched_boot.img​

adb reboot bootloader
fastboot flash boot magisk_patched_boot.img
fastboot reboot

Writable System​

To make the system writable we need to remount the partitions.

adb shell
su @#zxcvbnmasdfghjklqwertyuiop1234567890,.
remount

Now we need to reconnect and then we can write to the system (i.e. copy a file)

adb shell
cp /sdcard/myapp.apk /system/app

[Android Head-Units] mopfi:
Try both USB ports.

Plug the drive in turn the device on and then move a finger on the touchscreen. I do a left right movement. If that doesn't work you will need to do it with the mtk tools and a scatter file.

Hi!! Are there any way to disable calls from SIM card ? Thanks
[Android Head-Units] di_greenio:
Hi, I purchased the Junsun V1 pro 6gb/128gb and am pretty happy with it. All the important things connected and worked straight away which was grand. One thing I wanted to check is the battery draining problem and the cutting of the 2 wires to prevent this. I found the Junsun diagram and on there it seems it's the red and orange wires (that "look" to run from the main black block to the black power block for the head unit). The query I have is those wires on my loom run from the canbus white block to the black power block in the head unit. Pictures attached to hopefully show this a bit better. Excuse the terminology 😬Has anyone had any experience with this at all? TIA

[Android Head-Units] di_greenio:
I have the 6gb, not sure what chip. When you go into the menu after code 8878 it should say on the right in the middle "Erase All" I think. Then it asks you if you want to factory reset.
[Android Head-Units] TorstenH:
If your head unit is not storing your settings this may be worth a look on:

https://xdaforums.com/t/junsun-v1-p...ll-saved-data-gets-reset-after-reboot.4528057
[Android Head-Units] seth_space:
sounds interesting, thanks. Will try that.

The tpms usb module has internal storage so maybe that one works.
[Android Head-Units] seth_space:
nope, no succes. Tried two alternative launchers, vivid and free car launcher.. both not to my liking and the free car launcher immediately ask for a paid extension for standard tasks.

After that the junsun launcher started rebooting so i deleted the both new launchers.
[Android Head-Units] TorstenH:
How is this related to your previous message? Is only Junsun launcher not storing changes or is this a general issue on your head unit? Do stored radio stations surviving a reboot?

If you want to try another launcher I can suggest Agama because it's not overloaded with thousands of functions and doesn't show a Porsche (or other sports cars) like the Junsun launcher.
[Android Head-Units] seth_space:
i hoped an other launcher would solve these issues. But it has to be a nice launcher solving my needs also.

So for now, no stored data it seems and still hooked on the junsun launcher. Btw, not so bad when used in dual screen as i like to do.

I like constant navigation and a screen part free to choose. (weather,tpms,music etc) If the settings would have been stored i should start were i left.

[Android Head-Units] hurjup:
I've stuck with rooting my Junsun V1 Pro (8259), currently on v81 firmware. Never rooted anything before, so following the instructions worked only until the first problem. Some details that may be helpful:

The original and patched boot.img have different size, no idea if such a small difference is a problem or not (or if the patched one is bigger on purpose):

'fastboot flash boot magisk_patched-26100_7YcLI.img' results in an error message 'FAILED (remote: size too large)'

The closest to resolve the problem may 'fastboot flash -S 256M boot magisk_patched-26100_7YcLI.img' be, but I'm not certain whether it bricks my HU or does what I think its explanation means at all.

Any help appreciated.

PS:

Digging deeper, getting more and more confused. Magisk instructions states that the V1 Pro most probably doesn't have boot ramdisk, so the instructions in this thread shouldn't work (but I assume they do anyway). Also, 'recovery mode' (for patching a recovery image, according to the instructions) is ticked by default, however it shouldn't be / is not mentioned in the instructions what to do with it.
[Android Head-Units] hurjup:
Okay, it turned out that I got rw access through 'su @#zxcvbnmasdfghjklqwertyuiop1234567890,.' where I needed, so I am able to modify stuff, even if it is rather tedious.

Still interested what is the resolution for my problem above, however luckily it is not that urging anymore.

I have junsun V1 pro 2+32, car model is Peugeot 207, Canbus is working fine, everything works fine but i have an issue that the car warnings does not show on the display, for eyample if a light bulb is not working then normally would my car beep and show me a warning that the bulb is not working, Junsun does not seem to be able to read those warnings, so when my car beeps i am not able to know what my car is trying to tell me.

Any suggestions?

[Android Head-Units] marius.c:
Hi, Everyone,

I hope my message finds you well.

My name is Marius, from Bucharest – Romania.

On 7th of September, I bought and installed a Junsun Car Multimedia Player on a Skoda Octavia 2 Facelift.

You can find the details of the device below:

Device_Name: FF_866X

HMI: TSKJ.G6.A.Q.F.JC.2022.11.21.10.12

MCU: G6-TS.220713(VHD-SAT-9707D)

MEDIA: HC_v2.0.0_221026_1430(A7735)

CAN: VW-RZ-08-0033-B1 TS:1,0

BTV: BT.22.10.28.0935(04:7F:0E:C1:B1:27)

Custom build version: alps-mp-q0.mp5-V2.122.1_pvetec.q0mp5.spm8666p1.64_P2

Build number: sys_mssi_spm_64_cn-userdebug 10 QP1A.190711.020 p5spm8666p164P2 test-keys

RAM: 8 GB

Storage: 128 GB

Display: Q-Led

My kind request to you is to let me know if I have the latest firmware version and also the latest UI.

If not, can you assist me to upgrade the device, please?

According to the manual received next to the device, for “Volume” set-up I should have below options:

Media Volume

Navi Volume

BT Volume

Ring Volume

System Volume

According to “Manual_Volume_Options.jpg” attached.

Unfortunately, I have only one option: “Media Volume”, so I cannot setup the Volume for different apps, which is quite disturbing. You can see this on the picture attached “Device_Volume_Option.jpg”

Can I have your support in fixing this, please? I would like to be able to set-up volume level for each functionality: Media, Navi, BT, Ring and System.

Also, I found on Applet Store “Junsun Online”, GPS tracking App.

According to https://www.junsun-china.com/https-...uctmanageonline0014f34edfym2ryn-p00294p1.html, I already sent an email to junsun888@163.com for sending me the Registration Code. No reply yet from their side.

To be honest, I`m not sure if my device is Junsun V1 or Junsun V1pro. Considering I have 4G functionality on it, I can assume it is V1pro (according to “Junsun_Models.JPG” attached).

Thank you in advance for your kind and valuable support.

My kindest regards to all of you,

Marius
