As all of u know that oppo is a Chinese company and now a day China is the globel hub for electonic product.
Positive points of oppo f1s are:
1) front camera is batter than I phone 7
2)processor is slightly fast because of octa core processor
3) battery backup is decently quite better than all other segment phone
4) it have quite features like 3 gb Ram and 32 gb Rom, which makes phone sooopar fast
5) I am giving this phone 4.5 out of 5
6) and all the above thing is that this phone comes with a genuine price which of 17 k only
So my suggestions to all reader must go for it
