Ideas for future iPhones!

I have a suggestion for a new iPhone under screen cameras are possible right can we have it in the middle of the screen should fix the problem of not looking in you camera when taking selfie’s and battery’s there’s solid state batteries out there which are way better might experiment with that ? The design of the iPhone don’t change much maybe a flashlight upgrade? That would be something new in the smartphone industry hearth rate sensors? I don’t know if that’s a good idea yet don’t add too much features at once should save some up for future iPhones I hope I gave you guys some ideas greetings from ,Jaco van Genderen (14)
