When jio sim was launched then I purchased this mobile phone for my father. Now I tell about this phone. It has 2gb ram. Snapdragon octa core processor and 16 gb internal memory. The best thing in this mobile is its battery(2750mAh), which gives amazing battery backup of 2 day normally in internet. One more special thing in this phone is, it has Dolby Atoms sound with dual speakers, which gives very calm and clear sound. It has 13mp rear camera and 5 mp front camera, both are nice. The display quality of this phone is also very good.
