Hey friends, today I am sharing my personal experience about Coolpad cool 1 dual. I am using this phone from last some days and I am writing this review from this mobile. It is a worst mobile by coolpad it has good camera(dual rear camera) but there’s no memory card slot. But you can connect a pendrive through otg.Lots of people complaining about heating issues yes the device get heat’s up during charging it touches around 37-38°c. Phone also has hanging and lagging issue. Audio quality is good. Looking of this phone is also good. But Phone has many cons thats why it deserves 2 star only.
