Yi 4K Action Camera – Definitely GoPro Killer?

Written by

In the previous post, we talking about Sony FDRX3000, the high-end 4k action camera with impressive image stabilization from Sony. Today, we will go for another good budget 4k action camera for outdoor enthusiast who don’t want a GoPro. The Yi 4K Action Camera is a good GoPro alternative with a nice design, responsive touchscreen and plenty of features.


The Yi 4K Action Camera is a very well made, small, minimalist, and certainly, doesn’t look or feel cheap. Available in 3 color Night Black, Rose Gold and White Pearl. Unlike the other numerous Chinese products that have been baffling to use, this Yi 4K Action Camera is very easy to use with the intuitive software menus and helpful instruction manual. In my opinion, it easier to use than a GoPro HERO4.

Easy to navigate, thanks to the 2.19in (640×360) LCD touchscreen, which is covered by impact resistant Gorilla Glass for extra protection. There’s just one button on the top of the camera, which you’ll use to take photos or start/stop video recording. On the bottom is a standard tripod mount and is where you’ll access the battery. It’s slightly annoying that the battery must be removed to access the microSD card slot, but this is not a significant issue.

You will be little disappointed when opening the box, it’s worth noting that you don’t get any accessories in the box, no waterproof casing, no handlebar mount, no selfie stick adapter, just the camera. I really wish they would include the waterproof case but they don’t, so I’ll need to purchase a case. The package contains 1x YI 4K Action Camera, 1x rechargeable 1400mAh battery, 1x USB cable and 1x User Manual.




Yi 4K Action Camera comes with the touchscreen, means it’s quick and easy to switch between the different shooting modes and adjust settings such as the resolution. We found that the app is unnecessarily complicated to use when we just simply setting it up with a smartphone. However, the app is simple enough to use, allows quick and convenient video editing, image/video filters, and music options. You not just shoot and edit epic videos, but share them on social media instantly.

Inside the Yi 4K is pack with the new generation Ambarella A9SE75 chip, Sony IMX377 image sensor, and 7 layers of all glass. YI 4K Action Camera support encoding and delivers 3840×2160 ultra-clear 4K video resolution and 12M pixel photo even in poor lighting conditions.

The wide‑angle lens has a 155‑degree view and the camera offers a fixed aperture of f/2.8. The headline shooting mode is 4K (3840×2160), which is limited to 30fps but can record continuously for longer than any other at a whopping 120 minutes. You’ll need a reasonably large memory card to facilitate this and a fully charged battery.

Excellent touchscreen performance with smooth, no lag, and very responsive. Since the YI 4K action camera comes with a touchscreen on the back. It allows you to review your photos, videos, and adjust settings, which the GoPro lacks completely. Compare to a GoPro, you can’t tell how your picture or video looks like until you plug it in your computer, this is a huge advantage on YI 4K since most of us familiar and surely want to check our photos or videos after taking it on our phones.

The battery is rechargeable 1400mAh high voltage 4.4V lithium ion battery from Amperext Technology. The company claim, YI 4K can stand by up to 8 hours of standby time and can record 4K/30fps video for up to 120 minutes with a single charge. Yi 4K offers both Bluetooth and Wi-Fi. It supports 802.11a/b/g/n 2.4G/5GHz and anti-interference technology.

You may don’t want to shoot in 4K for any reasons whatever for the amount of storage space or saving the battery life. The Yi 4K action camera can also shoot in 2.5K, 1440p, 1080p, all the way down to 480p at 240fps. The highest resolution that supports 60fps is 1920×1440. Aside from all the different resolutions and framerates, you can choose shooting modes including timer, burst, time lapse and slow motion. You can also take still images as low as 5Mp, although most will use 12Mp (4000×3000).

Built-in Electronic Image Stabilization (EIS) with 3-axis gyroscope and 3-axis accelerometer detects position and motion changes. When the camera tilts, moves, shakes or experiences impact, the sensors uses image cross-border compensation algorithm to compensate the change and produce stable videos. Overall, we’re happy with the test footage from this 4k action camera which provide excellent levels of detail, even without using the higher resolutions on offer and still images are nice and sharp.

However, there are few things missing when compare to the GoPro. For example, it can’t shoot in 24fps, which provides a cinematic feel and the field of view is fixed, so you can’t swap between wide, medium and narrow as you can with a GoPro. You may needs a very high quality memory card for this camera, especially for 4K! Get at least a class 10 with a very high write speed like SanDisk Extreme Pro 64 GB Class 10 UHS-I 95 MBps Read MicroSD Memory Card.


The Yi 4K Action Camera is an accomplished device with a good design, handy touchscreen and provides excellent quality photos and video. Perfect for all uses: action, spectator sports, family events, etc. It doesn’t come with any accessories in the box and is missing features such as 24fps and different field of view modes. However, there is no 4k Action camera at this price range that can give you so much functionality like this.
