Just don't buy the phone no sense in complaining about it. The feature is there if you have the phone you have the option of NOT using it. Wether it is worth it is all in the hand of the holder.
I have only ever taken 2 or 3 "selfies" so I hardly ever use a front facing camera in the first place but I'm sure it will come in handy the next family vacation when my niece insists on taking family selfie style pics.
I have no doubt that my phone will take the best pics for that!
I really like this phone but I too question the decision for the dual front camera. It would have been okay with just a wide or even a normal lens. Then they could have utilized the space better and extend the second screen, which I find more useful. Sometimes, I wish you could just customize the design of a phone.
