Thanks for the informative reply and the pictures, they do really help.
From what I have read since I last posted would agree that both USB cables work? e.g. They both display on the Dashcam screen "MicroSD Card Reader Mode"
When you plug either of these cables into the computer both are recognised? You can tell in a Windows Computer as it will usually report a device has been plugged in.
If that is correct then you should see the card reader as a drive letter in Windows Explorer.
You should also be able to copy any of those files to your computer.
If you say yes to all of the above then we can move on to the Mobile phone wifi issues.
I don't own this camera so others will have to chip in for the best settings. Some settings are similar to other Viofo units so I'll chip in if I think of anything.
** Note about USB cables - not all are created equal. With a Viofo dashcam, the USB standard is loosely followed. Some 3rd party USB cables won't work. This could be the 3rd party USB cables are made cheaply with low-grade wire or was not designed to have above specification current drawn through them.
Best practice is to USB a known working cable then experiment with 3rd party products. Ideally, just purchase them from Viofo but this can be inconvenient as we all want it now
(That includes me lol)
