I have used a one plus 3 mobile. It is very bad in performance. Phone getting heat while using internet. And phone getting slow in some times. But features in this mobile is good. Finger print sensor, dual core etc but battery backup is less. Customer service is very bad. There is no service centers even in cities. If we get any problem we cant do anything without customer care. They are careless in customer service. Charges and billing charges is very high. Charges are not resonable. Network is very bad. Getting lot of ditortions in network. Body style is good. Sound reception is bad.
