Long after its release, the Realme X2 Pro's selfie camera got a review by DxOMark and the results aren't all that impressive. The 16MP selfie camera with f/2.0 aperture has no autofocus, but that's not its only issue as per the test. The phone's selfie game isn't bad, per se, but it's not able to compete with the flagships of its time, meaning late 2019. And maybe it shouldn't have to as the phone costs half of what the big players are asking while offering comparable hardware. Anyway, the overall score is 74 points and the selfie cam's key advantages are good color, decent detail...
