My C200 has destroyed 3 SD cards now, meaning they are undetectable and unreadable in any device. 
A new 128gb card was purchased with the camera, it was formatted in the camera and worked perfectly fine for 2 weeks, then I had a message saying it needed to be initialised, I tapped the button and had a failure warning, then the camera said there was no SD card installed.

i followed all instructions, hints and tips about resetting, powering off, deleting the app, etc, etc, but it wouldn't recognise the card again. 
I tried the card in my pc, another camera, a phone, and my tablet, but none of them detected the card!

I assumed it was a faulty card and purchased another one...well would you believe it, the same thing happened to the new card after it worked perfectly for a month, now that card is unreadable too!

i finally popped in an old 8gb card I had, that I knew was fine...the camera failed to format the card, and now it won't work in the device I took it from, and it can't be found via my PC!!
What's going on Tapo, is this a common problem with the C200, and should I return it as faulty?
