The trending phones in the market are redmi, vivo, oppo, samsung, apple etc.I think most of your friends would suggest redmi.As it is low cost and with more features.But the thing is they are making fools, the quality of build is bad.the display, the battery is the most disadvantaged.coming to vivo the great feature is camera its front camera is itself 24 megapixels and os is very trendy.now oppo other than the camera it is waste. Now Samsung what I am using, it may not have great features but it is very smooth to use and we get updates quickly.Comming to apple can not say about it because all of us kow about it it is great.
