So I bought this phone at MediaMarkt yesterday, being a bit unsure if I need a phone this size, but I wanted to try.
I absolutely loved it when unboxing and setting it up at home. Beautiful hardware, bright and crisp screen and snappy, intuitive software (coming from 4.3 on a bloated SGS3 the difference was absolutely huge to me).
The size was a bit extreme at first, but I managed to operate the phone with no problem. I could even use it with one hand to a great extent, though not as elegantly and safely as I could my S3.
It was a bit impractical to have a huge phone like this when I was on the go though. Although it went into all my pockets (jacket and pants) it was a bit heavy and bulky in them, but I think I would have easily adjusted to that in a couple of days.
Then, in the evening, I was looking forward to consume some media on the device in bed, which was absolutely great. Wether reading GAF, watching YT or playing some GTA III, I felt as if the increased screen size really benefited the experience a lot.
The same goes for the stereo speakers, which are tons better than my laptop's (Lenovo Yoga 2).
Unfortunately, while using the phone at lower than half brightness, I began noticing not only the red tint of the screen, which I knew of before but wasn't expecting to be that extreme, but also that the display was unevenly lit. It was darker towards the edges of the panel, prominently towards the right side of the screen when using the dropdown menu. When testing it out, I noticed the same thing in a couple of apps and webpages.
So, today I went back to MediaMarkt to get a replacement, but when I was presented with the choice of getting a refund or a replacement, I opted for the refund.
I simply had the feeling that the screen size is something I can live with on the go and appreciate when at home, but ultimately can't justify, when I could just as well use my convertible laptop at home (standing on its side it is damn great for watching shows in bed).
Just now however, I ordered a Nexus 5 because I enjoyed Android 5.0 so much (which is hard in Germany because Google doesn't sell it anymore).
I still think the Nexus 6 is a great phone if you want the big screen, but not if you want to want the big screen.
