Comparing it to like the Pixel 4. haha. Pixel 2/3's front cam were sharper, more detailed, but just that skins tones aren't as good. So i feel like if don't pixel peep too much, still considered good. but then the sensor itself is probably ****. A guess of mine is also that for 4a, the fixed focus lens' nearest focusing distance is not near enough (or maybe my arms too short. lol) so a lot of shot it looks like my face is slightly out of focus, but background is actually more in focus.
anyway, also in comparison, something in the same price range like realme xt, the sensor in the front cam is definitely more capable, just that it doesn't have the consistency of google processing in terms of colours and skin tones. lol.
screen brightness is better than pixel 4 outdoor, and i find it easy to use under the sun still.
It's mostly just in full auto mode for these shot in the stock google camera app. the close up shots of the phone cameras i think i used a bit of digital zoom. the 3rd shot is night sight mode.
