I forget to mention
What pain me most is "Resuming" Screen on WP.
Official MS apps(Music, Video & Games), seriously terrible apps I ever used .
For me is the lack of marketing to the general public on just how good this OS is. It's not general knowledge like iPhone and Android, and its not even being mentioned when customers are looking to buy a new phone. Yet when those of us who own WPs and are familiar with the ecosystem explain it to others they revel in finding out about it.
it is like when someone make a new app, if you look to the spot tv they usually only mention iOS and Android. "You can find the app in your App Store and Google Store"?. they forget about us? more crazier is to think than microsoft own xBox, so basically every app for game that support phone or tablet, like bf4 should be in the WP store, instead always and only Android and iOS. At least Rockstar make his app for WP too.
Hardly any app support for 1080p screens !!
The large font & button size on nearly every app including Nokia apps look totally absurd on high res screens. Only official MS apps seem to have this nailed (and ofcourse the wpcentral app).
Wish this would get sorted asap !
