So, Microsoft must be really joking with us. They had Win 10 for phones coming late 2015, we are in the end of February and nothing. My 640 has more bugs than I ever had with any Android custom rom (and I never had any flagship with lots of support).
Edge browser's quality is laughable. I use 4 sites mostly, on 3 of them I have a 50/50 chance of being able to open link or simply not opening them. Whenever I open a page after typing the address, half of the page is taken by the links to other websites that i visited, then i have to pretend that i want to type a new site and cancel so that i can see the entire page.
News/Sports apps are so muc h worse than they were. They look better but are so much slower now. 90% of the times when the tile is updated with some new news, I open the app and this news is not there. NOWHERE. So I have to wait more 1 or 2 hours until it finally appears there.
Here Maps worked perfectly for me before, now it starts to show me wrong bus/train times, suggesting crazy ways (on google maps it showed me a way that was 40 minutes, on Here Maps it showed another CLEARLY worst that would took 1h10 minutes, I ended going with the google one and it really took me 40 mins).
The music app, sooooo slow. waiting 4-5 seconds after pressing the play button everytime. argh.
The only thing that keeps me with WP right now is that it has (or at least SUPOSEDLY) apt-x support, which is kind of rare on Android. Really, you search on google and the only link that says something about it is that 'all lumia devices will have aptx after the win 8.1 denim update. and that is it. I guess win10 has it as well, but who knows? I am already looking for the few aptx android devices available
