Addition...
The rear camera has a 30% wider viewing angle than the front camera.
A small bug was also discovered - it is not possible to mirror or flip
the image of the rear camera in the application. I hope the manufacturer will fix this...
Also, when changing the name of the Wi-Fi network in the application,
it is displayed as an unknown network name, although the connection
to the gadget occurs correctly and the name of the network
in the smartphone is displayed correctly when connected to it.
It would be great if the front camera also shot in HDR mode...
This is like a wish for the future. Of course, if possible...
