Hello friends.before I am going to talk about I KALL N4 specifically I want to tell you something about the brand I KALL.friends I KALL is a such a brand avalable in market which is full filling the customers whishes like 4G VOLTE and OS marsallow. Useually you get these features in price above 6000rs normally. But here IKALL is offering these features within around 4800rs with a keyboard.so I think it’s a good product however according to my experiance it’s battery backup is not much good.and you cannot experiance the features of keyboard as such as a labtop or a laptab.but still within this price for educational purfus and for entrainment purfus it’s good tablet.
