Newbie owner of Opia2, but veteran owner of many dashcams. I recently received an Opia2, updated the firmware to version 2.5, formatted the sd card in the camera and put all settings to default. I've tried two different SD cards, one is a generic card sent with the camera (teamgroup? Class 10 64gb) and the other is a Sandisk 128gb Class 10. The issue I'm having is the camera will randomly stop recording without any warning or error and other times it will say "slow card" and stop recording. I am recording at 1440 30fps. This type of card is the fastest I know of and should work, the manual even recommends Sandisk. What am I doing wrong? Is there another SD card which is more compatible with the Opia2 or did I get a dud camera? I saw some posts on Amazon and other places with this issue and some people gave up and returned the camera. I like the features and video quality, so I want this to work. Help!
