I think the samsung galaxy S8+ is best smartphone but more expensive. It has a excellent construction and gorgeous looks. Display of this smartphone is very good and pretty. Camera quality of this smartphone is phenomenal and it captures very good photos. It works on nougat 7.0 and it uses octo-core processor. In this smartphone samsung cannot offer FM radio and temperature sensor.
The gaming performance is very excellent. But I personally tell you that the phone is over budget. In market many smartphones are available with same features at low price so think before buying this smartphone.
