My friend is using this phone from the last october 6/128 type. no major issues yet. no even a single hang. no heating issues. if saying about battery life I will rate 3.5/5 but still not bad. its light weight. slim and looks very shining too. it doesnt have touch sensor for unlock but the face detection is fast. sound quality is good. one of the issue is about camera. if we zoom a pic taken from the main camera, its quality is poor. front cam also will show little fair than original. but if u r a selfie lover u will be enjoying it. the rate for such specs is what made me buy the stuff but genuinly saying I m right with this. overall I will give 4.2/5 : )
