Have been using coolpad note 3 for the past couple of months.
here is my review:
The phone has never lagged or slowed down as long as I have used it.
I have gamed, watched movies, listened to music(mediocre quality) and other daily stuff.
The phone tends to get HOT while playing games, and many times while charging.
It definitely doesnt last the entire day and I find myself looking for the charger in the evenings. Camera quality is bad compared to other phones in this price bracket(even though the shutter speed is fast).
The phone still doesnt have an official marshmallow OTA update. Users are asked to update via a third party tool(SPflash), using this tool might not be easy for most of the regular users.
The screen quality is average.
Best feature is the finger print scanner which is surprisingly faster than some of the high-end phones.
Not much customer service outlets which has left many customers disappointed.
Overall its an average phone.
