I did what you suggested and immediately upon reboot, the Android file came back with today's date and time. Will wait to see if the error keeps coming back.
I had the same issue. Deleted the Android and Lost. Dir folders from the sd card rebooted and haven't had the issue since. Just go to my files and on ur external sd card there will be a folder called Android just delete it. Your system will generate a new one when you reboot. May be the Android folder from our previous phones causes some compatibility issue.
Just an update on this. Deleting the android folder just provided a placebo effect. It didnt really help, the error was back after a few hours. The only thing i could do is back up the data and format the sd card. Quite a few images on my sd card were corrupt. Might be worth a try if you're facing the issue though.
I know you already found your solution, but for others that come looking, wiping the device cache fixed it for me.
Hold Bixby & Volume up, then power.
Release when the android/samsung screen comes up
Choose "wipe device cache"
Choose "reboot your device"
Same problems with A50. With original Samsung microSD card, 125GB. At insert he ask for formatting. After 20 minutes the phone is restarting, asking again for formating , followed by another restart, another format ...
Just insane !
The SD card work very well in any computer !
Samsung it is a brand name already, but they just follow the path of Iphone, Nokia who abuse the consumer !
Hello I am getting the above error using a scan disc 128 gb . Should I get a new card? I have a Pony Elite-X micro sdxc card. Would that work? Thanks for any help/recommendations.
