I’m using I phone 7 but I need IPhone se2 features can I update software and use those features like in cam portrait option

Hi,

if you need to use "Portrait mode" on your IPhone 7 you can't, It is applicable only on these models: iPhone SE (2nd generation), iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone XR, iPhone XS, iPhone XS Max, iPhone X, iPhone 8Plus, iPhone 7 Plus.

NO because your iPhone 7 does not have the necessary hardware to use the portrait feature.
