What I love about the HTC One is the build quality, it's top notch. The size of the phone is pretty big though compared by my S4 (both 5") but I don't think it really matters that much.
I just upgraded to lollipop and seems google deleted fast sound options that were accessible by holding the power button there seems to be no silent mode at all as well..
So what phone to get? No HTC and size does not matter. I am really thinking of the Nexus 6 but as it is now I think it is overpriced. And the thing is, I am not that in a hurry, I just want to see my options and take my time in deciding.
I'm disappointed at the battery of the Nexus 6. If I'm too lug that big a phone, I expect it to last through the day easily.
LG G3 or the OnePlus One if I didn't want to spend a lot of money, for me.
