Do I need mobile QR for every wallet related process?

Hi, basically I'm new to the whole world and today when I was looking to connect my wallet to a protocol, the only option to connect seemed to be QR.

My phone's back camera got broken recently. Will I need to verify and process every operation like accesing my wallet, connecting it, making transactions with QR? Is there no way around it?

I haven't even made a single transaction yet, I think metamask doesn't ask for this since there are adresses but will this be trouble even other than connecting your wallet to a protocol or somewhere spesific?

Also, I'm getting a cold wallet soon which I've never experienced with one but I think I've heard of it's useage cases with QR. Will this not being able to use QR be trouble for me?

Sorry If I'm in the wrong place to aks this. Thanks.
