SD problem

[SanRavRC]

I have a class 10 (128 GB) micro SD card in my Z2!!

When I try recording 4K videos to the SD card, it doesn't work properly! When I try to play the video it says "Cannot play video! Invalid URL" sometimes the whole video file is corrupted!!
I have recorded 4K videos on this SD card previously as well without any problem!!

This problem isn't there when recorded to the internal storage!!

Any idea why this happens??

It might be something faulty with your SD-card. Have you tried to format your SD-card to see if this can help? Otherwise, I would suggest that you try another SD-card to see if the same thing occur.

128GB means probably the card is UHS I or II,over class 10 so there shouldn't be any problem.You could try a low level format.

As Hampus said, I formated the SD card! (Via PC). When I insert it back, it doesn't work!! The SD card is detected by the phone, but it's not mounted!! The option "Mount SD Card" is live, but nothing happens when I tap it other than the notification popping in drawer saying "Preparing SD card"!

But it doesn't get mounted!!
But the SD works perfectly with my PC!! No response in the phone!!

Before I had only that 4K recording problem but now the whole SD isn't working on mobile! (But perfectly works on PC)

Any solutions please???

Couldn't try with another SD because I couldn't find any!

I didn't change any file system as well while formatting!

This is strange,I suggest you check if the phone detects the card in safe mode:

Nope, the Safe Mode doesn't mount it too!!! 😞

This is strange,maybe you could stop by a sony service and have the device checked?

Thanks a lot for the support!!

I got it fixed! I think it was a problem with the format I did (But didn't change any from the default settings)

And as one of my friends suggested me, I downloaded a software called SD Formatter and did a full erase with it! And now it's working!

4K problem is also solved as it seems to be! Nothing happened when I recorded a video like it happened early!

Thank You!!
