Just update my 1520 to win10m. So far so good.

Have tested the win10 on my Lumia 1520. A lot of bug which sometimes can drive you to madness. Facebook apps is still at minimum function. Camera apps seem to generate not so nice picture and quite often go crazy with pop up pop in menu, crazy zoom in out and switch front back camera. Dunno if this is win10 issue or phantom touch issue. Microsoft still need to prove to the world that win10 mobile can be useful if they can produce what customer want. To do so, they need to have a goal and not relay on what customer keep telling them. Compare to android, it still have a long way to go but whether their current customer are willing to wait until then is still a question.

Will try that later. Do you have phantom touch?

This continuum features is one of the Ubuntu phone concept which is very interesting.
The biggest challenge is make the developers believe in this part.
But the most important of all, Microsoft must stop changing the game of Windows Phone. Rapid changing is not good. Imagine you have built an apps for Windows phone but later Microsoft said the standard need to be changed and then they change again and again. From WP 7, 8, to 10. All are using different concept in a way that piss off developer to keep supporting the OS.
