I am using Yunique YU4711 for almost 1 year and I didn't face any big problem. But yes I face some bug and hanging problems but not continuously. Its price tag is also awesome only under 5k and I believe that best smartphone in 5k it is. Its Performance is not as good but mediocre Camera performance in back is good but not great and in front very harsh. In this way I complete my review and also I recommend to buy this Yunique phone which is very Unique.
