I am using a Samsung Galaxy core prime since January 2015. It has been almost 8 months and I am quite satisfied with the performance. Let me explain its feedback one by one
The rear camera quality is good with a auto focus and flash.
Front camera is 2 mega pixel but takes good quality of pics.
3.The phones runs smoothly while playing games because of good RAM
If we talk about the Battery, it easily last for the day even if you are continuously using it
Display is awesome and having a great gestures
Over all the phone is quite good and I will recommend to them who are having a 7-8 k of budget and want a branded smart phone.
