- Wish I could still use this gem of a device. It was the next best thing to iOS back in 2014 when Android was buggy & lagged a lot.
Too bad WinPhone10 OS was discontinued, it was the next best thing to iOS back in 2014.
Pros- Battery Life
- Smooth Operating System
- Did not require more RAM
- WP10 OS was not Hardware Hungry
- Dependable Device - No Bugs No Lags
Cons- Lack of App Ecosystem
- Limited customizations

Microsoft abandoned windows 10 mobile and this seems to be the main problem for this mobile. It stuck very often and there are no very few apps for this phone. Noone seems to be interested to make apps for windows phone.

View answers - Good enough phone for 2015. I don't recommend it because of lacklaster store and buggy os.
Comfortable phone. It is moderately fast. battery without use lasts for 1.5 day. Medium use for 1 day. Heavy use for 6 hours. It crashes sometimes if you upgrade to windows 10. It's more stable with windows 8 but it has way less features. I recommend it only at 90$ or less. The battery, signal and gps has failed me in times of need.
Pros- Gets the job done
- Acceptable screen
- Acceptable speed
Cons- Windows Store
- Crashes and bugs
- Not great apps

Score
In this case, to determine the score we evaluate 5 general aspects:
- Design and screen
- Hardware and performance
- Camera
- Connectivity
- Battery
Once these 5 factors have been rated, we introduce the price variable. This means that any two devices with the same ratings get a different Ki score for quality vs price.
Even a device objectively worse than another may have a higher Ki score if it has a better price.
The Ki varies as time goes by. As new devices with better specifications enter the market the Ki score of older devices will go down, always being compensated of their decrease in price.
