- I own a Galaxy note 4 and a Lumia 1520
So what keeps me on the 1520
- OS, although not fully functional and full of issues works overall better than android. Phone never slows down. No one crash in ages. Big tiles make things easier also on big screens (it means you can do many things with one hand if you know how to put tiles and how to handle the device properly)
- Windows sucks less data than Google does. I won't stretch as far as saying it offers more privacy as they both closely cooperate with governments so privacy on these devices is utopic. However, it feels better.
- The phone used as a photo/videocamera goes well above my expectations. To the point that i often leave my M4/3 camera at home unless i really need to shoot something afar. Pictures are really gorgeous and night pictures come out beautiful out of the box. Videos are just a tad worse but still much much over what an average user needs. I was impressed one year ago and things are only improving in that department
- Simplicity. Despite the menus being messed up in these versions (8.1 DP) once you find the key item the submenus are easy to understand and do what they say. Android is somewhat better structured in terms of main menus but the subs (at least in all my Samsung devices and the HTC too at times) are hard to find.
- UI looks good on WP (but not very customizable). While having to use Android because i need it, the icon concept for me keeps looking very childish. I have applied a varied of custom UIs over time and i have found a good compromise (but i lose the key functions of the TouchWiz on the Note). For some reason all those childish icons have me tired and bored.
What keeps me from migrating to the WinPhone platform altogether.
- OS still in the works (Basic functions missing, customization still low despite the hype, browsers very subpar, lack of proper language tools, lack of proper mail management, lack of key apps i need for work. I don't like onedrive either. It's so buggy that i lost tons of documents i really needed so i
Will it keep me on it? 100% sure if MSFT adds what i am missing (In particular better browser, proper chinese inputs, good email client, in the style of K9 on Android or better....the outlook app on Android looks fine but it's somewhat boring). I can stretch as far as RE-Buying all apps i need on the WP platform on the condition that they make things happen quick. In lack of proper patching and improvements i may go for Blackberry, which already allows access to all the android apps i need without being on a Google platform and offering a good level of safety and, well, email apps are just top notch.
