Let us start with the hardware part. Yi 4k looks almost same as that of GoPro device, even the waterproof case appears somewhat like GoPro product. Some resemblance is found in mobile applications as well as in mounting systems. The front side of Yi 4k is equipped with a lens and LED that provides current camera status indication. The 2.2 inch wide LCD screen is protected with Gorilla Glass whereas on top portion you will find holes for speaker and dual microphone. On the right side, a small flap is covering MicroUSB charging port and the left side is left bare.

Connectivity Bluetooth and dual-band Wi-Fi
Lens 155-degree wide-angle/ F2.8 aperture
Max photo resolution 12-megapixels
LCD display 2.19”touchscreen

Pros and Cons:

Impressive image quality No mounts/waterproof included
Ultimate battery life You have to control everything with one button under water- that’s really difficult
Touch screen display is of very rich quality It is little difficult to access MicroSD slot
Super-reliable advanced Wi-Fi connectivity You will find it difficult to use LCD screen in direct Sunlight
Image stabilization feature can be activated at 1080p Additional protective housing is must for underwater usage


You will find a USB charging cable with your camera- nothing else. You need to buy you own power adapter. This is really sad when we compare it with GoPro Hero4 Black where box include waterproof case and mounting clips. You will have to pay $40 to get official Yi waterproof case and the best part is that it is compatible with GoPro device.

The shutter speed can be adjusted as per need to boost the recording performance in night hours.
