Oppo f3 is very good smartphone and sound quality is very good. the highlight here is the front dual camera setup 16mp primary and 8mp secondry camera. the 16mp front camera is the one used by default while the secondry 8mp camera is for wide angles selfies. image results were fantastic as expected in the most occasions from the front camera in both single and dual mode.inthis phone 4gb ram and comes with 64gb internal storage.the oppo f3 proves to be a fantestic phone overall but with a few quirks here and there. they are not deal breakers and if you are looking for the one of the best selfi camera phones the oppo f3 is one of our top choices. more other many feuters. thanks.
