the trick to having sharp picture is to use portrait mode. try taking a selfie with normal mode and then another with portrait. make sure there is no camera shake. and then zoom in on both photos. you will see what i mean.
same trick works on rear cam as well.. 12mp is too grainy for me. when viewing the picture as is, it is fine. but as soon as you zoom in on the photos, the grain is very significant. but using portrait mode solves this. the problem is that it takes up more space so im assuming portrait uses the 200mp sensor.. but properties of the photo shows 12mp though so this is weird.
another workaround is to use 50 and 200mp but we all know how those 2 modes goes.. the forced processing on 50 and 200 is a hit and miss and would sometimes render the photos unuseable. i still dont understand why they dont give us an option to turn it off and just take normal actual viewfinder picture like the 12mp does.
