Phone stuck in selfie mode?

[Android Central Question]

Hello,i have an samsung smartphone (sm-g360)

the problem with it is that the camera is stuck in selfie mode,this happened after i had my screen replaced becouse it was broken (cracked)
i want to know if i can fix it or if it is a hardware problem and i need to send it to an smartphone repair store

To give u guys an more in depth info about it
i tried to clear cache/data on the camera default app
i even reset the phone from factory
i tried several apps from the play store for camera
i tried an app called Photomath,which says as follows: "your device doesen't have a supported camera"

and the problem goes as follows : i still have the "switch to selfie/rear camera" button in the upper right corner but its not working,if i click on it it refreshes the camera and it still gives the selfie mode

thanks in advance for any advice given

It seems likely that damage or disturbance of some kind was done when the screen was repaired, assuming that the rear camera was working before that.
