TikTok app shows conflicting iPhone models
When I'm on the tiktok app on my phone, it says it's an iphone 9 and also an iphone 7 plus.
iPhone 7 Plus, iOS 15
Exactly how does this relate to TikTok?
If you are saying the number A1784 is on the back cover, and A1661 is shown within Settings, it would appear that the back has been replaced.
Otherwise you will need to provide further details.
