I'm happy with mine. Had it about 3 weeks. Nice to be back with HTC. Had several from years past and liked them all. Coming from a MXPE(my 3rd phablet in a row) most recently it is nice to be at a more manageable phone/screen size. No more phablets for me.
After a couple of wifi adjustments my signal is better and since I only use it at home it's now pretty much a non issue. RF signal could be better, but I've not dropped any calls and they always sound clear so maybe a non issue also.
Love all the themeing options. Nice touch HTC. Keeps it interesting. I don't get the screen complaints from the amoled fans. My screen looks awesome, sharp and clear, brightness set around 75% is fine. I have little reason to use it in sunlight except for an occasional call and it's easy to see for that.
Build quality is top notch, love it. A very minimal case keeps it secure in hand.
I never cared much for sense in years past, but find I'm liking it a lot now. Blink feed is fine as well and I enjoy having it set up and handy. My one other launcher is Action Launcher and I swap back and forth to keep it interesting. I like the way HTC makes is so easy to change launchers.
Battery life has been fabulous. My MXPE was struggling to get thru a day, same size batteries and of course with the bigger screen I can understand the increased power demand, but while it used to go all day it frequently would begin to falter by evening far to much. The HTC has no problem going all day with plenty left over.
The speakers sound great. Less volume than the MXPE, but much richer, more satisfying, better sounding tone quality. I think all phones should have dual speakers and high end models like the Note 7 and Iphones which are insanely priced should come standard with dual speakers. It just sounds better.
I think the HTC 10 is under rated by a long shot and while most reviewers gave it a pretty good score, the buying public mostly gave it a pass. Samsung's marketing engine pretty much blows everything else out of the water, but after having a couple of samsungs over the years I've never quite swallowed all that is Samsung hype. Amoled, yeah, I get that, people love it, but not all of us and personally I dislike it so glad we have the choice. the rest of Samsung is equally overblown IMO. In any case I'm done with them. I hope HTC continues to make good devices. As an old fan it's nice to be back. Just my .02
