Selfies with the phone's rear camera
Most phones at an acceptable price have poor quality front cameras (for selfies) and the rear cameras take excellent pictures, I thought it would be good to have a local mirroring solution of the active phone screen, only via bluetooth, on a disabled phone , without card or smaller internet (only used as a monitor), attached to the back of the phone so you can take selfies with the rear camera.
Both attached to a Selfie Stick, you can take normal photos or selfies, of good quality only with the rear camera, by simply turning it 180 degrees.
I use the internet mirroring solution, but very often it proved ineffective during vacations. The lack of internet on the mountain, in caves or in places not covered by my telephone network or in many cases the high price for internet access led me to I give up the solution.
A plugin installed in your application would solve this problem simply and efficiently.
