Now a days there are many budget smartphones in the market basically under or between 10k to 15k. So who one is trying to buy a new smartphone under 15k he will definitely confused. By the way here I am going to give my experience and opinions towards Coolpad Note 3S which my brother bought from amazon which was cost him around 9999. It has 3GB of Ram and 16 GB of internal storage and it is running with android 6 and coolui os. I am using this phone as my secondary mobile. It was very handy and the phone sometimes lag ( after using it 8 months) because of lower version of snapdragon chipset. Its battery backup is good when comparing with its battery capacity i.e 3000MAh. It does not supports VoLTE. It has also a fast finger print sensor. It has a rear 13 MP camera came with manual focousing and auto focus features. In low light conditions and in day the photos are bright but colour correction is not so good and photos have a few noise. Coolpad has also a good customer service in our locality. Overally my opinion is that when it came to market it was a compititer but now a days many compititive brands are lauched. So check reviews and opinions before buying.Thank You
