Android seems to forget mirroring the rear camera

[Jaskin]

Dear all,

I bought a Pumpkin from Amazon (https://www.amazon.de/gp/product/B075F6HFYY) with Android 7.1.1.
I just installed a rear view camera and it is working fine. I connected it to the 12V cigarette plug in the trunk of my Golf V.
I additionally use the AV IN app to enable the cam while driving, besides when using the reverse gear of the car.

Now I face the following issue:
The camera image is mirrored - so I use the mirror option in the driving options. (OK)
Now I start the reverse camera and the camera image is fine. (OK)
Now I start the reverse camera again and the software seems to forget about the mirroring option and it is wrong again. (NOK)
I have to restart the app in order to get the correct mirroring again. (NOK)

My question: Is there somewhere in the Android system another option which mirrors the camera image and which is not forgotten by the AV IN app?

Thats not true, at first start, the image is mirrored. When sending the app in the background and opening the app again, the image is not mirrored anymore.

Hi，
it is quite strange that the image is mirrored at your first start.But it is real that the AV-IN app doesn't support reverse mirror image function. Hope your kind understanding.

Even if I dont use the AV IN app, the image is mirrored only the first time I set the reverse gear.
