Vivo has given an AMOLED panel in this phone. The Vivo S1 comes with an in-display fingerprint sensor. The borders of the display are very thin. But the part border is slightly wide.
Vivo S1 is made available in two colors- Diamond Black and Skyline Blue. We have reviewed the Diamond Black Unit. The rear part of it is laminated, and here is a diamond pattern design and gradient color finish. Diamond pattern appears on the back on the basis of light fall, which is very beautiful in appearance.
However, we did not like the material used on the backpanel of Vivo S1. Scratch marks are easily on this. To the company here Redmi Note 7 Pro ,Review) Like Corning Gorilla Glass should have been given. The Vivo S1 comes with a triple rear camera setup. The camera module is of bulging. But they get protection from the mantle rim on the edge.
Vivo has expressed confidence in plastic frames that have turned on the edge. For this reason the phone grip is good. The backpanel is not found on the smooth frame. Vivo has a volume button with a power button on the right side of the handset. These can be easily accessible. Like Vivo Z1 Pro, Vivo S1 also has a separate button for Google Assistant.

In Vivo S1, we were disappointed to see the micro-USB port. Because at this price, companies have started giving USB Type-C port. MicroUSB port has found a place with loudspeakers and 3.5mm headphone jack on the lower back. While the sim tray is on the left side.

Funtches have a command center like iOS.

Vivo S1 Performance, Battery Life and Camera
The MediaTek Helio P65 used in Vivo S1 plays well in common use. You will never complain. The smartphone launches the app quickly. You can play any game or use app on Google Play Store. We did not have to wait long to open any app. Vivo S1 is also under control over battery consumption, especially when the phone is not being used. There was no problem in multitasking due to using 6 GB RAM variants. We did not need to close any app in the background.
The AMOLED panel of Vivo S1 comes with the best viewing angle. There was not much difficulty in reading outside on the phone. However, the speaker on the lower back does not have a very loud sound. Because of this, there is no fun in media entertainment on Vivo S1. We tested face recognition in the device with an in-display fingerprint sensor. The in-display scanner quickly unlocks the phone by scanning the finger. Even if the face unlock smartphone is not the most secure way to unlock. But it is very fast and convenient.
Pubji mobile on Vivo S1 ran on the medium preset. The graphics was set on the balanced and the frame rate on medium. We played this game on the phone for about 20 minutes. During this time the handset was heated and battery consumption was 5 percent.

Vivo S1 will be known for the best battery life. It easily supported for about one and a half days. During this time we conducted benchmark testing. Took some pictures. During this time, WhatsApp account on the device was also active. In our HD video loop test, the smartphone died in 16 hours 38 minutes.

Vivo S1’s camera sample tap to see in full-size
The camera app is the only one with Vivo Z1 Pro. You have many modes. HDRs, live photos, filters and aperture mode are Quvik togle. There is a quick togle to switch between regular and wide angle lenses.
Looking at the price, we will say that the pictures taken from the camera of Vivo S1 were also weaker than the average. The phone focused fast in daylight. But we found that the photos were underxposed. The details were satisfactory. Could go to distant texuals to study. If this scene will be captured with an ultra-wind-angle sensor, then there is a better exposure scene. But in this situation the details decrease.
Close up shots were good. Vivo S1 locked the focus rapidly. The exposure was also accurate. However, Colors did not always come accurate. The portrait mode comes with different lightening effects. Which you can use before tapping on the shutter button. The output had good edge detection.
Vivo has a separate aperture mode which is used to take a Bokeh shot. While taking a portrait shot in this mode, we found that Blur Effect was not consistent. Edge detection was also nothing special in this mode.
The camera has an AI portrait framing feature that helps you to make a scene properly. The Vivo S1 takes the shot automatically when set the frame.
The camera performance of Vivo S1 is average even in low light, as the phone did not succeed in capturing details. We did not find any night mode in the camera app. Perhaps this mode would improve the performance of the phone’s camera in low light. Details in the selfie come but the Vivo S1 overtook the scene. You can also take a portrait shot in selfie mode. The phone in our experience was right in terms of age detection.
You will be able to record the most 1080 pixels videos from primary and selfie cameras. We found that there was no video stabilization in Vivo S1. Given the price, this was shocking information.
Our decision
Vivo S1 is another smartphone of the Vivo brand at a price less than Rs 20,000. Its design is attractive and it comes with in-display fingprint sensor. The phone has used the new MediaTek Helio P65 processor, which is a little better than MediaTek Helio P70 in some benchmark tests. Talking about the processor capacity, the performance of Vivo S1 was around the handset with Qualcomm Snapdragon 660 processor, which will be available for about Rs 10,000 less than its price today.
The battery life of Vivo S1 is good. But its camera performance disappointed us. Given the budget of Rs 19,990, you have strong options like Realme X (Review) or Oppo K3 (Review). Redmi K20 can be purchased by spending a little more.
