I have had zero problems with my 3 cameras using the 16GB Micro SD Cards that came with the units when I purchased them. A few months ago I bought 128GB Cards to give me more recording history in case there is a time delay in turning off the camera after an accident and I have had nothing but problems. This is with all 3 dashcams. I am on the latest firmware 1.009. This is a shout out to determine who else is having or not having this problem with 128GB cards and resolving this once and for all so I can rely on these cameras to be recording properly when an accident happens.
