annoying problem/defect - phone or microSD card?

Problem: opening/playing audio files (mp3) from an SD card will randomly take a long time to perform, on a per-file basis, all the while locking-up the phone (not even audio/ringing volume adjustments work until the file finally opens, sometimes minutes later, which needless to say is an eternity).

The issue seems to happen at random, and with random audio files. Strangely, the same audio file exhibiting the issue can play at a later date/time with zero problems.

Perhaps a clue as to the problem: video files (mp4) never have issues. This also means I can seek/skip through a given video file with no issues, ever.

The microSD card is a 64GB Sandisk (which is a replacement for the other 64GB Sandisk I had originally - I replaced it, thinking the card was defective).

So yea, is the phone defective? If so, I don't understand how (strange defect, sometimes working and sometimes not).

have you tested with another card, or tried to play the audio files from a SD card reader/USB stick from your computer?

Same problem with 2 different cards, same brand and model though.

99% sure they are different batches in any case, as the packaging was different.

Maybe it's the software / player. Some software tries to do things like looking up song information online. Once it has that information it might either update the file or cache the info elsewhere.

There might be a setting for you to disable this, or you could try a different player app.

Edit: or the files, something about specific CDs where the encoding stalls the player while it decodes to WAV for playback. The next time this happens you might note down the CD / songs then look into the properties using a PC if necessary.

How can I test file access on the card via PC or whatever like the other person suggested? I'm not really sure how.

1. Get a USB card reader for your PC if it didn't come with a built-in card reader.
2. Unplug SD card from phone.
3. Plug SD card into reader.
4. Use music player software on PC.

That takes money. I don't want to spend money.

I have an adapter for it to go to a larger format SD card or whatever (I just realized), so I suppose I'll try it later with my laptop.

Anyway, if it works, determining it's the phone... what kind of defect in a phone causes something like this?

I thought either it can or can't read SD cards. Why be picky and so random with it?

Also, I'm 99% sure it's not the software settings.
