well, it really your word against mine. You are saying that all the models have this problem, I am saying the exact contrary! I have seen this problem only on my phone. On the biggest italian forum there are almost 15 person which have this problem. you have an idea of how many phones apple has sold? Nobody has this problem. here, how many from all over the wod are we to have this problem? maybe 30? by making a nit precise count, talking about math, could it be the 0,01% of the phones sold? You think that apple will be caring of such a few persons? They are happy with people that "settle down" waiting for the update. If everyone goes and claims for a swap unit they will begin to reconsider it as a problem. Anyway, really, for now it's not my problem anymore for now. So you can act as you think it's better. But I think much more I won the lottery by picking a faulty one and being among the 0,1% of the people who have this problem. I don't know exactly which problem you have, but a problem such the one I had in my previous model was really affecting the reliability of the phone, so we would not have had all the enthusiastic reviews we have on the iphone 12 family. So try to look beyond and ask for a replace unit. That's my suggestion. It solved my problem. If you're stuck on software problem and it's ok for you, than it's ok for everybody!

I'm happy I had the will to go on with a new model. Good luck to you!!
