I had purchased Coolpad cool 1 Dual 3GB/32GB smartphone. It heats too much while using camera more than 5 minutes. Apart from this Front camera is too good. It has 8 megapixel front camera which gives clear selfie experience in comparison of Redmi Note 4. It 13 megapixel back camera is also captures nice picture & it 5 megapixel rear secondary camera which clicks back and white photo. The other issue this phone has is of external storage. This phone has no support of Micro SD card.
