I guess what really strikes me about this image of the specs is that anyone could have created it... it says right at the top, in English, that it's the "LG Nexus5 2015" and then some Korean writing. It seems to be specifically written to the US market. Maybe the Korean language doesn't have Korean words for the LG company, or Nexus5, but I can NOT believe they don't have a symbol for the year 2015. And not really having the full specs.... battery, or what type of screen except to say it was 5.2" and 2K resolution... sounds very vague.
Personally, I have been dealing with may sub-standard cameras, and to just say a 13 megapixel camera is sub-standard... it doesn't have to be a 20 megapixel camera to be great... I'd be very happy with 13 megapixel camera if it took GOOD pictures over a 20 megapixel that took so/so pictures.
Also, I'm not sure how reliable any stories are that come from the "Android Authority" website... what is their track record on early spec reports?
