I have bought this phone and using this. 16Gb internal memory with 2Gb RAM. Till now I didn’t get any software problem and hanging problem. There is a heating issue in the phone when I play games other wise the phone is working as normal. The rare camera is decent , you will fall in love with the color clarity of day light snap , but the rare camera must be more improve . The front camera is very good than rare camera. 3100mah battery is good.T he screen clarity is good but very delicate if mobile fall down the screen will break. So need to handle with care.Main draw back is no option of expandable memory. UTG option is added advantage. This is a 4G LTE supportable dual sim mobile.
