Default Flash is ruining my photographs at night!!

Have tried the stock camera app and VSCOCAM as well - but still the flash is ruining my photographs. Haven't got a case on the phone when taking these images and to be honest... it's annoying as hell! Tried it with my girlfriends black Z1 as mine is white - and hers does the same...!

So, I assume that the flash is interfering with what the sensor is picking up, in which case... the phone isn't fit for purpose..?
