I recently upgraded my Sony Xperia Mini to the latest Android ICS version and right after that I am facing this issue. Whenever I try to copy some MP3 files to the device I get the warning message as “The device might not be able to read it” as though unreadable format but it just normal MP3 files which worked in the previous Gingerbread version. Why I am getting this error now? Is there anyway to fix this problem?
