My first 4g smart phn is infinix note 4, I buy this phn one year ago, its price is very low, any one can buy this phne. This is basically china product, but my according this is a very good phne. This phne is slitely weight but normal. Its battry capacity is 4300 mah, battery not removal, and main thing is that it is not heatable. Its camera is hd, I think it's camera is better than many other phnes. It's browsing is very fast. It is speker is two and it designed well. l like this phne still I using this phne.
