Recently a Chinese user on the service Weibo posted up some shots. Supposedly taken by the Huawei Nexus 6P and the Sony Xperia Z5. These are 2 of the highest rated phones on Dxomark right now. So you can expect these two to be battling it out for the best camera on Android in the future. There is no EXIF data to confirm either phone, so take it with a grain of salt.
Sadly these are all night images so they aren’t going to be the best quality. While both sets images look pretty good, considering the shooting conditions. I gotta say I think the Nexus 6P stands out as the winner when you zoom in. At 100% the details are sharper and there is less noise in the image. Looks like that big sensor really is making a difference.
