Vivo S1 Summary

The S1 is the first Vivo S series smartphone to launch in India. The S series focuses on style and it cannot be denied that the S1 looks elegant. It comes in two colour variants called Diamond Black and Skyline Blue. We had the Diamond Black variant that had a catchy diamond pattern on the back. Vivo has put an AMOLED screen of 6.38 inches on the S1. It has good viewing angles and adequate brightness when outdoors. It also houses an on-screen fingerprint scanner. The Vivo S1 has a waterdrop notch that houses the selfie camera.

On the back, the S1 has a triple camera configuration consisting of a 16-megapixel primary sensor, an 8-megapixel ultra-wide-angle lens and a 2-megapixel depth sensor. We were not impressed by the fact that the S1 has a Micro-USB port, while most other smartphones in this price range have a Type-C port.

Vivo includes the S1 with FunTouch OS that runs on Android 9 Pie. It has customizations and comes with some preinstalled applications. The Vivo S1 works with a MediaTek Helio P65 SoC and is the first smartphone in India to do so. There are three variants of the Vivo S1: 4 GB of RAM with 128 GB of internal storage, 6 GB of RAM with 64 GB of internal storage and 6 GB of RAM with 128 GB of internal storage. We had the high-end variant for review and did not face any problems in daily use.

We play games like PUBG Mobile that the S1 ran on medium configurations. The phone warmed to the touch after playing for 20 minutes. The camera is where the S1 still needs some work since we were not happy with its performance. It does a decent daylight job but offers less than average performance in low light. The 4,500 mAh battery offers good battery life and Vivo includes a fast 18W charger in the box.

The Vivo S1 feels expensive compared to some of its competitors such as Realme X and Oppo K3.
