So been using the camera for the last few days on the x play (comparing to the s6 edge)
So far i gotta say... for the price the camera really isnt bad at all...
I did have to switch to a different camera application to get better quality pictures though (i switched to Camera FV-5)
and the difference in quality on the pictures is big!
but yes the camera does suffer from poor low light images. the images are just very noisy unfortunately but overall you really can't complain about the camera at this price point.
in day light the pictures are almost as good as s6 edge (with diff camera app though )
I'll try and take some comparison pictures later
Its a real shame that the camera gesture can not be used to launch any third party camera app though :-(
