iPhone 8/Plus Smart HDR in Iphone 8 plus

[MyPhone99]

Hi There,
I have an iphone xs max and i really like the front camera in that , got to know that it uses Smart HDR.
Now i want to have a back up iphone ( looking for 8 plus as i really like the design and i want bigger screen) and it seems it use auto HDR ( not the smart HDR)
But both phones uses 7 megapixel so i wonder is Smart HDR a software thing or hardware thing?
Just Curious , Is there any software or app or setting that i can apply in iphone 8 plus front camera and make it look like xs max's front camera?

Thanks in advance.

There is HDR, Smart HDR and Next-gen Smart HDR (11 line)

Probably A12 image processor is capable to capture more images (in various exposure) and then merge them to the one.

Improved camera performance is Apple's number one sales pitch for new iPhones. The 8 Plus uses older tech.

Sorry for the late response
Actually you can apply a trick by turning on the hdr by default and tweaking the exposure a little bit
When you’re taking a selfie just choose the exposure over the highlights
And then use the slider to bump up the brightness a bit
Then take the shot
Guarantee both shadows and highlights are gonna be even better the Smart Hdr
But this trick will make the image noisy and sharpened alot
