That's Android beautification mode, by default it's set to high value which is bad. You have to reduce it to zero, but still it will slightly beautify it, but it will not take fake looking photos.
Fake looking photos appear on beautification mode set to medium or high.
Apple will launch beautification mode on 2020 with some gimmicky name and then it will be a game changer feature, like portrait lightning mode which is nothing but a bad joke. It only works when the lightning is awesome to begin with. Lol
