camera not working properly

I have an iphone 7+ but the camera doesnt seem to work on the normal 1x zoom. 2x + works but 1x doesn’t. Even for other apps like instagram, the camera automatically turns on at 2x zoom. Snapchat doesn’t open at all cause of this issue. I think camera apps dont work, like a QR code scanner didnt open at all. The flashlight doesnt work when I toggle it from the control panel. It works with the camera app though, the flash. I did try factory resetting my iphone and resetting my settings but nothing worked. Please help me with this issue. Thank you :)
