iPhone 17 is uselss and iStore is no help

Do not buy the iphone 17, it will be a night mare. I pre-ordered the phone September and it has been hell. Early October I experienced problems took it to the store, they found nothing just restored software. Again early Dec I experience problems took it in February we seating in March they give me same response that nothing wrong with my phone, I ask how when it gives me problems. Now they keeping the phone with no resolution.

The store was kind to loan me a phone but also that phone is a nightmare.

Stay away.
