I have the same camera. i bought it from "estore" (spelling?) or some such. the ad they had for the cam really dolled up this camera. They sold me on the "novatek" chip--that was before I found this site...
That said, I have a 32gb card in it and i leave it in parking mode continuous record and its been rock solid. this is on the FHD setting..
knee jerk response is your card is fake, or damaged. the cam itself is fake or otherwise faulty. its not much that can go wrong in these gadgets.
there is a tool on you can download to test the cards authenticity. I dont know if off hand but you can search this site, or someone will see this and respond.
there is a dedicated forum for this model here,
https://dashcamtalk.com/forum/forums/gsxxxx.8/ , so search in there.
i using an authentic sandisk 32gb and have not had any issues out of this cam. its been in the car for a few days and its been solid.
Finally, people on here will bash this camera and put it down by calling it cheap, inferior, etc. I think those terms are unnecessary and they do not help in any way. That said, this site is THE site to be at to find as much info in one place about this cam and others. I have had zero issues with it and its a good starter cam to get your feet wet in the dash cam game. the ONLY thing with this cam that i dont like is it cant use higher than an sdhc (32gb) card.
welcome bro. you will easily spend more money than you care to as this site is so helpful ad there is so many toys on here.
