I get a "Slow Card" error all the time and as a result videos are often not synchronized video/sound and the video playback speed will fluctuate throughout the videos while the audio remains at the proper playback speed

I got multiple SD card read errors, no SD card errors and about half of my files were corrupted from strange reboots and freezes

I have the Sandisk Extreme pro 32GB, the Sandisk Extreme 64GB, and Lexar 1000x 64GB and these have all displayed the "Slow Card" error.

Basically, with 3 different SD cards,and the Yi 4K had problems saving files and would randomly have SD card errors.

sd included in bundle gets a "Slow Card" error when shooting in 1080/60 which isn't even the highest capture setting.-"Slow Card" error causes videos to get corrupted, De-synced video/audio

i have sandisk extreme and pny microSD cards, and i would frequently get SD card errors when powering on the camera

Good camera with good quality, however it's SD compatibility is an issue, using a sandisk U3 64gb, receommended by Xiaomi, there are various slow card errors, various formats have been done and issue still persists

Well there's an issue out there where this camera will throw "Slow Card" errors and will prevent you from recording or even turning off the camera at times.

First I tried it with a Samsung EVO Select 64gb card, but it gave me Slow Card error

I just had a slow card error then locked up yesterday while using their suggested SD card (need to remove the battery so it will turn off)

i think 54 C is considerably hot for a camera of this type especially during longer usage duration

The camera is so heavily reliant on my smart phone that I'm confused as to why I don't just buy a 4k recording smart phone...

O cannot recommend this camera for anything.
