Nothing like spending a calm quarantined evening with your fingertips .125 inches above your new phone, making small adjustments for the perfect placement😜😬
It depends on the store. The one where I am is only doing express pickup. I asked about them installing screen protectors, and they said no. You can only buy them for self-installation.
I can only add one data point but I had Apple install the Belkin screen protector on my 12 Pro and I did not see any scratches. If there is one, it’s has not been noticed by me.
I bought my iPhone 12 Pro Max from 5th Ave NYC and they did not have the machine, they said maybe tomorrow. They were applying themselves. The apple person tried but she messed up and returned it, and offered I comeback tomorrow.
