Well I wouldn't call it crying when you have basic features that work on your Win8.1 phone that don't work at all. Personally, I was shocked at how buggy my 950XL was. Sure, Win10 Mobile is still almost Beta (though they say it's RTM) but I've encountered tons of bugs. Whether they are small are not is irrelevant to me because if I'm having to reset my phone 5+ times a day that's an issue. Some people may be having no issues and that's great if that's true. I wish I was one of those people. I'm also one of those people that owned a buttery smooth 1520 and learned on my own I needed to do a hard reset of my 950XL after upgrading before people were advising. Doing a hard reset on a brand new phone after day 2 blew my mind. So my own experience hasn't been flawless like some others to say the least.
I experience, app crashes regularly. I still see some apps opening or performing slowly. Some games I paid a few bucks for don't even work (GTA). I see bugs regularly when customizing things from my start menu to custom sound notifications. I get blank tiles, I get dropped 5ghz wifi signals. I've had complete phone lock ups a few times. My DT-903 settings keep resetting. I can keep going. Yes, a few random bugs are normal on a new phone but I find this OS to be much further from RTM than they would like us to believe. So I for one would rather see a big bug fix update this year and not 4 months from now.
