This is the best company I ever seen but this xiaomi mi max prime is not so cool product from xiaomi. Talking about its build desgin it has a 6.5 screen which is very large then a normal phone. Difficult to fit pocket and heavy then other device and the battery also drain fast because of its big screen the battery is non removable its a another issue for this device. The big problem in this device is that the sim slot is hybrid of we put 2 sims then we cant put our sd card in it we need to sacrifise a sim for sd card. this are some issues I face in this device. This device is not good at this price range in my oppinion
