Xperia Z3 Dual cannot save files on SD card.

[ayub99]

After I upgraded my phone (Xperia Z3 Dual D6633) to Android 5.0.2., the phone cannot save or write files on SD card. My SD card is original and not corrupted. I found out that this problem does not happen on my friend's Z3 running Android 4.4.4. The only solution for me now is to restart my phone every 5 mins.

I have posted some screenshots 

Tried to take a picture. Save picture was set to SD card

Any suggestion?

Do you have any antivirus or taskillers or battery apps? 

Have you consider repairing your phone with PCC and reformating your SD card?

Also, boot on safe mode and see if you keep experiencing the same issues

If I was you, I would reformat the SD card, if that doesn't work then I would repair my phone with PCC

I think this is a bug.

Unmonting and mounting the card solves the problem for sometime.
