I have 2 Samsung galaxy S20 FE phones that have exactly same issues. The phones are different (one white and one blue) but both purchased from same store at the same time. At least once a day each phone stops recognizing SD Cards inside it. No error messages displayed. The only way I know by seeing some apps that installed on SD card showing grey wired icons. The only way to fix the issue is to reboot the phone. The SD cards in both phone are Sandisk 256mb cards. One is brand new and one is one year old that I moved from my old Galaxy s9. When I remove the cards and try to copy files on them from and to computer via laptop card reader I have no issues with the cards. I tried to replace card trays in both phones and reset the phone to factory settings but it did not resolve the issue. After I restored all my applications from backups the issue came back on both phones. I'm not sure what can be the issue, may be software. Maybe anti spyware programs like MCafee detects something dangerous on the SD cards and disconnects them ?
Same exact issue here. Crazy annoying as I don't even realize it happened until my phone starts complaining about low storage because my video/photos from camera app switch over to internal and fill it up...
interesting. what sd card do you use ? and how you charge your phone ? how often it is disconnects? I have this issue on two phones. and it is random. is your phone also galaxy s20 fe ?
My wife, son and myself all have the s20fe and have this same problem. Every single time I open my camera on a new day I have to confirm saving photos to SD card. A few months ago If I lost service for any reason it would also dismount the SD card. Samsung must have fixed something but still just annoying as all hell. Honestly this phone **bleep**, I like the s21 (work phone) better even with the lack of the SD card. Its not faster on bench testing but it seems to have far less problems. No matter I'll trade them in next release.
