I connected my S23+, 256Gb to my Windows 10 Pro using an USB cable, and mounted it as an external drive.
I then proceeded to copy a Windows folder and subfolders containing several thousand mp3 files to the music folder on the phone. The process starts fine and shows files being copied, the remaining percentage of files and time, and then after just a few percent completion (probably several hundred files total) it unexpectedly quits, with no error message, just a beep when the file copy dialog exits. This happens consistently each time I try to copy many files at once
I checked the Windows Event Viewer but could not find any relevant events.
I had other Android phones in the past including S8 and S21 and I never encountered this issue.
