iPhone 16 pro freezing

Same issue; I set up the new phone, and none of the Apple apps work. Youtube work fine but when i open watch app or messages app, the phone freezes and i have to force restart it. I contacted apple support and they suggested that I have to reset my phone again - I am not doing that because i have already reset it 4 times. Then, they asked me to go in person and resolve it. I got an appointment for 3 days later. So apple does not have a solution to this.

I am having the same issue - I couldn’t even transfer my old phone backup over - I had to use the iCloud backup and it took over 13 hours. I had 138GB used on my old phone. My new phone is 256, but got an error of not enough memory when transferring it via phone to phone. I want to reset it to see if it stops the slowness and lag when I try to open any apps, but I don’t want to wait another 13 hours to use my phone. Also, half of my apps are all white grids.
