But that is just your evaluation tbh.....I didn't see where they rated the Z5 the best on a camera phone. Maybe you have a faulty unit? I don't know......
The fact that until now they scored it higher than any other smartphone other than S6 Edge + says they think it's the joint best. Otherwise what's the point in the scoring and graph ? And no I don't have a faulty unit. Likewise even ignoring the Z5 discrepancy doesn't explain the difference in S6 Edge + over Note 5 or the Droid Turbo 2 over the Moto X Pure which each together share same cameras & software.
The point and crux remains. There are definite discrepancies on that graph - that makes the scoring questionable to keep holding it up as some form of beacon.
If my personal experience can be just flippantly cast aside as "just your evaluation" ... Then the same can be said for dxo. It's only someone else's evaluation, so why put it on a pedestal ?
