Perfect SE 2 would be (IMO), taking into account costs:
- 4.3" edge-to-edge LCD display. Similar size/form factor to current SE but with no bezels.
- Face ID
- A11 Bionic
- 3GB RAM
- Limited colors (to improve production costs): Space Grey or Silver
- 64GB or 128GB storage
- 12MP rear/7MP front camera (same as iPhone X)
So basically the first gen iPhone X, in a smaller form factor similar size to the first gen SE. LCD panel instead of OLED to reduce costs. Would cost around $550-$599 for 64GB.
I would throw my money at Apple if something like that was released.
