Hey guiess if you want to take a good mobile in low cost then you can take moto c plus .
It costs 6999 rupees but sometimes you can get it @5999 on Amazon .
It is having 2 GB RAM and 16 GB ROM .
And a 8+ 2 camera with dual flash ( front and back) .
And also 4000 mAh battery.
It is very good and users friendly .
But the bad thing is it is having guest mood and users mood.
If your phone is in users mood and your phone is locked then if someone switch on to guest mood then the phone will show all your personal photos and videos.
I am personally using this .
It is all-over good cellphone.
