Samsung galaxy J1 is a best android phone under 6k price with 4g network. My dad is using it as his primary cell phone. Iam really impressed with its style and design. It has got lots of amazing features. Screen and touch quality is really great. It is really resposive and quick. But iam not really happy with RAM. Screen veiwing angle is really great. Even though it is 6k begdet phone, it has many great features. It is easy to use and user friendly. Reliablity and furability of this phone is really great my dad is using this phone from last 8 months still no complaints. Sound quality is really good. It is value for money and really worth buying it.
