Have a look at the DxOMark Mobile ratings for smartphones. (http://www.dxomark.com/Mobiles) In first place is the Sony Xperia Z5, followed by the Samsung S6 Edge, Google Nexus 6P, LG G4, Samsung Note 4, Moto X Style, Sony Xperia Z3+, iPhone 6 Plus , iPhone 6 and then the iPhone 6S in 10th place.
I have around 50 individual albums for each separate smartphone I have personally used. See here https://www.flickr.com/photos/gavinfabl100/albums .
The only phones I have not used are the Z3+ and Nexus 6P. I have used the Z3 Compact though. All I can say is that DxOMark scorings in my opinion are a nonsense.
I would place the S6 Edge Plus/Note 5/LG G4 near the top followed by the iPhone 6S Plus. Depending if video or photo was more important to you could tweak the results marginally one way or another. I would then place the Sony phones below all of the above and all the older iPhones. The Moto X Style takes good photos overall too.
Now in my testing the Z5 doesn’t take poor shots, it is just not at the same standard unless you switch to manual modes and take full control of the shooting parameters. Well, if I use third party apps with the iPhone 6S Plus same thing happens too – incredible shots. But that is not real world usage.
So how would YOU rank the phones scored by DxOmark?
