Vivo has put a 6.38-inch AMOLED display on the S1. It has good viewing angles and adequate brightness when outdoors. It also houses an in-display fingerprint scanner. The Vivo S1 has a waterdrop notch that houses the selfie camera.
Vivo ships the S1 with FunTouch OS running on top of Android 9 Pie. It has customisations and comes with a few apps preinstalled. The Vivo S1 is powered by a MediaTek Helio P65 SoC and is the first smartphone in India to do so. There are three variants of the Vivo S1, 4GB RAM with 128GB storage, 6GB RAM with 64GB of storage and 6GB RAM with 128GB of storage. We had the top-end variant for review and it did not face any issues in day-to-day usage.
At the back, the S1 sports a triple camera setup consisting of a 16-megapixel primary sensor, an 8-megapixel ultra-wide-angle lens and a 2-megapixel depth sensor. We weren’t impressed with the fact that the S1 sports a Micro-USB port while most other smartphones in this price range have a Type-C port.
