The dark theme is uncomfortable for my eyes (ok, maybe it's fault of my poor quality TN matrix, but anyway I don't want to see it). I doubt anyone wants to read white text on a black background.
The letters are gigantic and are optimized for hi-resolution monitors.
Also, as I understand despite new release Google still haven't solved the problem of apps and Google itself siphoning all available data from the phone.
Also I hate how Google manages updates. I had to install a Hangouts app. First, it copied the Google Account details I entered into it, into the phone and now all other apps can access them which I never wanted. Luckily I was smart enough to make a separate account for this purpose. Second, sometimes when I start it it says that it is updating Google Play Services (so I have to humbly wait until Hangouts does its important business) without even asking if I want that or not. Why does the messenger takes a work of a package manager I cannot understand. Probably, because they need to install new telemetry modules even if the user didn't activate Google Play. Very unpleasant impression.
New apps are required to request privileges like contact list access and location before using them. You can deny them. What other issues do you want to solve?

It doesn't. You want to use hangouts. In this case GPS is effectively a library hangouts uses to auth/connect to servers. Since it's the critical building block, it updates itself.
I do! Much less eye strain and easier to read for me. In fact, I read your comment in white text on a black background. My eyes are very sensitive to light in general though.
* Each pixel in an LCD has 3 subpixels (red, green, blue). There is a light source behind the pixels. To display black, white, or anything in between (gray), all 3 subpixels allow an equal amount of light through. What controls the shade is the amount of light allowed through each. For black, the lowest possible amount of light is allowed through.
* On an OLED display, like the one in my phone, each pixel emits its own light and can be controlled independently. A black pixel on an OLED display emits practically 0 light and even uses less power as a result. This is why blacks look way better on OLED displays.
* See for yourself. Use your phone in a dark room and fill the screen with white only and then try again with black.
* You know how black absorbs light and white reflects light? Black does not absorb light because it is black. It's black because it absorbs light.
I pay per gigabyte with a prepaid plan for my phone, because I'm not paying $40/month for phone service when I can pay less than half that, so blindly clicking a web page and having 20MB quickly used up sucks.
First time this has ever happened since I've owned the device... Which is many years!
And if one of the biggest Web company can't do web page well then I guess the rest of the Web Pages get a free pass for not well optimised.
