I have a Huawei P9Lite and got from one to the other day problems with the SD card. I have received a notification that the SD card is being prepared and checked for errors, but I can't access files such as music and pictures. The notification does not disappear. In addition, my smartphone runs slower and crashes. When I remove the card my phone is back to normal and when I put the card in the PC I can access everything. Can someone help me?
The simplest solution would be a new SD card and data transfer.
if it still does not work you know it is due to the content or on the phone maybe even.
or you could simply transfer images / vid / music from the sd card on the pc
then format the sd card and try again.
if it still does not work then cell phone backups and factory settings.
Take the data down the PC and format the card in the phone.
should work, otherwise, buy new ones.
Unfortunately, I can't format it in my phone because it can't be read correctly: /
Format all data into the PC, then format it on the PC, take it out and try to format it on the phone.
Only as a suggestion.
