Some people might believe that the magnetic holders are the best, I would not say magnetic holder is the best, if it is not strong enough, the phones will come off when there is some vibration when you drive.
Here I am going to introduce one car holder that I believe is the most reliable.
Obviously it is very stylish and you can see how it works from the pictures below.
This is a good looking car holder that is very reliable and stable on the car and it is not going to block your view
It is good for most of the cell phone models, the width ranges from 50mm to 100mm, it is good for cell phone with a screen from 3 inch to 6.3 inch.
Here are 2 animation GIF pictures to better show you how it works, your phone will be held very tightly, it will not easily fall down even when the roads bump so much.
You can see from the below picture that it will not block your view because it is placed on the air vent.
Here you can see the knob in the middle that you can rotate it in different angles.
