SD Card problem - Can't save videos - Buttons doesn't work

[kezzmania]

Hi all,
I have 4k Sports Ultra HD All Winner cam ( fuxin4k30imx179-sdv ) and really big problem with its SD card and saving videos. When I start video recording it shows me that it is recording(red icon is blinking) but then I cannot stop it and it doesn't saving videos...buttons are not working...must put off battery. I updated firmware to the latest but still have a problem. I have Transcend 16 GB Micro HC SD card - class 10. But there is strange situation when I put the other card ( class 4), it works but without recording, just taking photos. I know it is slow, but all buttons are working. I formated SD card class 10 with ext-2 but it doesnt working again. Former SD card worked well till one moment, then this problem appears...but that Kingston SD card is healthy too

thanks in advance for help,
Kezza

Seems like your camera does not share this opinion

Haha, yes Nutsey. True But I bought another one and it is not working, too. A new one...hmmm

use ChkFlsh tool free or h2testw tool free to check SD cards and USB storage.

Generally, you must have a U3 micro sd card for 4k recordings!

Thanks all for help and advices. This card is a new and healthy but I'm pretty sure that I must buy other type of it.

Some cheap cams just dont like Kingston cards. But Samsung EVO cards always work fine.
