Ok I’ll still say it, looks more likely to be the 11 than XR lens. Based on info on apples website. Be sure to come back to me once they’ve done the tear down videos. If I’m wrong I’m wrong. Either way it’s going to be a great camera for the money.
If it has the iPhone 11 lens/sensor, then Night Mode would be available, period.
Night Mode requires 100% Focus Pixels on the sensor, which is only available on iPhone 11.
The SE2 is a low-cost iPhone. Apple is not about to do a custom sensor for a low-volume product and then deliberately leave out Night Mode. It makes no sense from a Tim Cook $ perspective.
