i had a windows phone enjoyed it for games hated the Facebook app and marketplace layout and lack off regular updates and features.
so i switched back to iphone (currently have a iphone 5c)
iv also had Android last one was a S3 huge fan of android but the price to replace my screen was 200odd each time vs the iphone's $30 haha
I have a white Samsung Galaxy S5.. I just got the Android Marshmallow update 2 days ago. Before this I had an iPhone 5S and I liked it at first... but after a while I hated it. Battery life sucked so I got the GS5
