Hi! I use a 64GB microSD as an expanded storage on my LG Stylo 4. Following the notification on the phone, I formatted the SD card to "portable storage". However, when apps tried to open microSD files, I got error messages such as "file is damaged" or " file is empty". But if I copy the same file to the internal drive, the apps can open all the fils just fine. Is there a way to fix the problem? Thank you!
