One plus is an awesome smartphone with extremely unique great design. It supports 3 gb ram and good camara which we habe seen in other one plus devices this camera does well in low light condition also this is a dual sim phone with hybrid sim card try which means either u can use it as dual sim phone or you can use it as a single sim + sd card phone.
This has 16 gigs of internal memory whixh ia quite less. So I like this phone but I wont take it for myself.
It runs oxygen os which is not stable right now.
U have other good option as well.
Peace.
