I bought it last year ( 2016) in august from local retailer. Sound quality is dull. It has a good look. It has 1gb ram and 1GHz quardcore processor. After buying this my regular visit to service center get started. Fist of all this phone had network issue, then charging issue, headphone jeck and charging jeck got replaced. Battery 2000mh. It has pathetic battery backup. Heats like heater when using jio net.camera is 8mp and 5mp rear and front respectively. Camera is ok. My phone rear camera is filled up with dust I don’t know how it get in there so it clicks dim photos.it has lagging problem. It runs on android 5.1. Well if you guys want cheap 4g phones for jio net then I do not recommend this one because there are many phone which cost way lower then this one.I hope my review is helpful for you. It is not just review it is my experience with this heating machine.Thank you.
