Nokia Lumia 525
I have been using this phone for 4 months now and have found it to be perfect for my use. I wanted a basic smartphone that is fast, has a good battery life and an ok primary camera. Despite the lack of flash, I found everything in Nokia Lumia 525.
great camera; wonderful GPU; 1GB RAM; Windows Phone 8.1 works like charm; Decent battery life (2 days without constant Wi-Fi and 3G; Great app support from Windows; Nokia Branding and hardware; Awesome sound and music experience; Plays 720p and 1080p videos without breaking a sweat
no flash for back camera; no front camera (i don't care about it; Heats up sometimes while playing games for long period of time
