I love this phone because of the advanced finger print lock feature, all I have to do is to touch the phone and I am entered into the world of technology. It also protects my apps which is more convenient. The best thing which I like about the phone is that it has dual pixel rear camera, Hi-Fi music and AI game mode. The dual pixel camera makes my pictures more realistic because it doubles up the sensors of the camera. When it comes to Hi-FI music it’s more audible and it helps me to go ahead with my day with good music. I am a gamer, owning Vivo X21 has given me a chance to go on with the game rather than pausing it when I get a call!
