i have used window phone for 2 years ( nokia lumia 925) with their OS window 8.1. it is a great OS with good/unique user interface experience.

However the window apps is terrible. very lack in support and develop. Many of my friend always get the first hand experience on the lates/trending app while i still need to wait for like 6 month or 3 months for the apps to be appeared in the window store.

Now i'm using a android phone because the internal speaker on my lumia925 is dead, not sure why. Sometime i do miss the features on the window phones such as the glance screen and live tiles

still... android phone doesn't disappointed me as much as the windows phone.

A smartphone without great apps..... hmmm think again :3
