Matrix 64 megapixels
Image resolution 9248 x 6920
Zoom Digital
Flash Dual LED

8K video recording No
4K video recording 30 FPS

Lenses (64 MP +8 MP +2 MP)

Vivo S15 has 3 cameras at the back and main the camera is so amazing that it can take some amazing shots. The Vivo S15 main Camera is 64 megapixel F/1.9. What makes this camera setup even more awesome is that this camera lens is combined with the wide aperture of F/1.9, the wider the aperture the more light will it collect and the more sharp the image and video quality will be. This Vivo S15 can record video at 4K at 60 FPS. This is amazing the video will contain more details thanks to its good optimization software and the high-end processor. You can also record 1080P at 120FPS which will be slow motion. There is Digital image stabilization on the main lens only. This is not as impressive as optical image stabilization but, this will make the camera experience more stable and more accurate. The Vivo S15 has 3 more camera lenses. Let’s talk about that in detail.


Triple 64 MP, f/1.9, 26mm (wide), 1/1.73″, 0.8µm, PDAF
8 MP, f/2.2, 120˚ (ultrawide)
2 MP, f/2.4, (macro)
Features Dual-LED flash, HDR, panorama

As I mentioned above that this 64 MP sensor is good. But this Vivo S15 has 2 more camera lenses. There is another camera sensor of 8MP which is an ultra-wide camera. And it’s so wide the field of view is 120 degrees which are wider than other smartphones. This camera sensor also has some amazing autofocus. This sensor can take amazing shots with high accuracy. Its aperture is F/2.2, which makes it sharp and contains good tons on subjects. This Vivo S15 has an amazing camera setup, with fast autofocus lenses, high sensors, and good software optimization.


Single 32 MP, f/2.0, 22mm (wide), 1/2.74″, 0.8µm
Features Panorama, HDR
Video 1080p@30fps, gyro-EIS

When it comes to selfie cameras the Vivo S15 has a single-punch whole camera of 32MP which has the largest pixels. This single-punch whole camera contain some awesome details when it comes to daytime shots. At night time this camera sensor struggles a lot.  And what makes me more concerned is about its aperture because its aperture, which is only F/2.0 which means the photos will look accurate as other smartphones, also this camera will be good at night because the sensor is big with a wider aperture, which means the selfie camera can capture more light. The camera video capabilities are also kept at 1080P at 30FPS only.


Wi-Fi standard Wi-Fi 6
Bluetooth version 5.2
USB type USB Type-C
NFC* Yes

This Vivo S15 is launching with the Wi-Fi 6 which is faster, more efficient, and gives you less latency when compared to the Wi-Fi 5. Which will make the user experience smoother and faster. There is also the support of Bluetooth 5.2. Which is also faster and more efficient than version 5.1. Vivo S15 has the USB type C gen 2.0 support which makes sense because of the 66 watts of fast wire charging so it must need more bandwidth for charging speeds. It also helps with the data transfer because it helps with the faster read and write speeds. Vivo S15 also has NFC support which is also useful. You can pay, and transfer files at high speeds thanks to the NFC support.


Speakers Yes, with stereo speakers
Headphone audio jack No

The Vivo S15 comes with stereo speakers. This Vivo S15 has nice sound quality with a nice amount of bass in it. This will help in gaming because there are two speakers one at the bottom and one at the top which will help gamers. Video watching and hearing to music also going to be good. There is no 3.5mm headphone jack which is neither good nor bad.


Colors Blue, Black, Yellow

The Vivo S15 is going to lunch in three different colors. Blue, Black, and Yellow. OPPO is known for its premium colors with good contexts. I like the Black color because it looks better than these two colors.


This smartphone is costing around $450 which is way cheaper than the Samsung Galaxy S22 Ultra and the iPhone 13 pro max.

Final Thoughts:

If you are looking for a good Flagship phone, good gaming phone, good design, good display, and amazing performance then this Vivo S15 is worth buying. Because it has all the needs that a good consumer needs.
