Hi guys,
I'm using also a Hero smartphone which is unable to read the covers as Mathieu mentioned it.
I have experienced that the covers are not correctly readed by AIMP software (MP3 file reader) for example (and other devices).
Using this software, the cover is badly displayed (it seems the file encoding is wrong).
As I'm not familiar with the different tag version, I'm wondering if this problem is linked with tag version (2.3 to 2.4) or if the file encoding used by MP3Tag could be enhanced to enable the "sensitive" devices or software to work with.
Thank you for your answer.
