I have using Reddi Note 4 4GB for about 1 month.
But now I am facing some problems.
First Problem is the pictures taken in daylight are average and lacks clarity. But Low light pictures are very dull from both rear and front facing camera and another is that the camera which cannot record videos in 4K resolution. Technically speaking the processor of this phone does have the ability to handle 4K resolution videos.
But I don't know why Redmi note 4 makers didn't put it in this phone.
And the Second big problem with me is charging.
My One of the reasons to choose Redmi Note 4 is the battery capacity. Reddi Note 4 offers a battery of 4000mAH which is huge. But the sad part of this phone is that it does not support quick charging. When I put it in charging it took 3 hours and 24 min to fully charged from 0 to 100% .
I am a student and I have not more time to charging this phone.
