I just had a thought, you should prob check you dont already have an app of the same name installed, incase this overwrites it, as if that is the case you need to back up that original apk first before trying the newer version just in case.

The 4x4 info, tried to install the app but got the same message as RR.
I then looked in the installed apps and i already have the carinfo app installed so it didn't do anything, i set it up a while ago to show my car but doesn't do anything else like show which door is open etc like i see on other units.
installed the app but it said is was updating the existing one, so no change. Pity
I enabled rear sensors and now it shows a vehicle on the screen when in reverse.
do you guys know what decoder version you have ? ive attached a translated picture of mine
also in system info it says for me, what is yours
CAN version: Range-v31-240304
System version: TS18.2.2_20250820.112825_WINDOW-THEME1-V2
CarSetting Version: master-mxy.20250514_1189
Did you get or have an icon in your apps that has that grey car icon ?, as it seems the carinfo can be launched in different modes, such as 4x4 info and reverse mode , as i think they are both being done by the same app.
My head is LF-DW-TS18-QLED-202509
