[M_Fekry]

I had xperia C4 dual nearly a year ago and i looked forward using it with android 6.

todoy my dream has been achieved and finally updated my mobile to the latest sofware version (android 6).

However, there is a problem has ocured directly after updates had finished.

my moblie ejecting my 64 GB sanDisk SD card unexpectedly every time i turned it on. althought the same SD card was working well since i bought it two months ago with the old software before updating.

Could you please help me to solve this problem ?

The messege appeared on mobile device display is:
