I use my BB as an MP3 player. I put a lot of albums on the 8GB micro SD card.
Everything works fine.
My BB is set to lock after 5 mins. So if I listen to music for more than 5 minutes, the BB automatically locks. At that point, nothing unusual happens, and I can continue to listen to music.
However, If i need to do something else with the BB, I have to enter the password to unlock it.
At that point, the Media player freezes. Checking that in more details, it looks like the BB is actually, moving in "Scanning mode" checking for all media items on the SDcard to detect new files.
My Media card was formated with the device. I tried to delete all the "BBthumbs.dat" files as indicated in the this thread Fix for Media Player Not Scanning For Music, Stuck on Scan, or Constant Reboots
but not luck. Any idea what could cause this?
