Long-term optimizing work:
1. Optimization of power consumption. As of FW 1.31, battery life is increased by 40mins.
2. Focus on the optimization regarding playback failure or problems with certain music files.
3. Increasing speed of updating lib, and fix rare freezes when updating lib
4. Fixing inaccuracies in CUE playback.
Improvements & added functions that would be included in the upcoming two firmware versions:
1. Optimized playback of certain music files.
2. Red battery icon to alert users to low battery.
Amendment plan which takes time that temporarily can’t confirm the completion progress:
1. Support the playback of DSD music files
2. Usage with self-supplied power device through OTG cable. (Note: More testing needed)
3. Support for embedded & external cover and cover named by its folder, cover, front and song title like in Foobar2000
4. Extend the limitations to the resolution and file size of the cover picture.
5. Fix possible minor distortion on left channel when playing high dynamic music in OGG format.
6. Support for OGG files’ tag information, such as album, title, artist, genre, embedded cover e.t.c
7. Support user-created playlists like M3U files.
8. To allow switching on “Hold” to switch off the display screen.
Unrealizable functions or unsolvable problems due to software framework and the base limit:
1. Can’t display the album and genre for CUE file.
2. Can’t change the cover and lyrics display option (i.e. If cover and lyrics coexists, it would scroll display the lyrics using transparent font on top of its cover. If there is no lyrics, it would only scroll display ID3 information. If there is no cover, it would display the way as in FW 1.23).
3. Slow speed in skipping songs; it would only skip to next song even if clicked ten times continuously, while it would skip to the tenth by clicking ten times on other machines.
4. Can’t add “Play by album“ function under artist option of play by category.
5. Can’t support exFAT, FAT format and 64KB cluster of FAT32 under 64G. (Workaround: Just use the inbuilt function to format the TF card?)
6. TF card content still not displayed on computer in the following circumstances: Connect X3 without TF card to computer, and then insert one TF card X3 after connection finished (Happens only on Windows XP)
7. Under play interface, it can’t remember its store path after several returns (go back to main menu, then back to play interface, and then click the back button again.)
When the “Memory Play” is on, it can’t remember current playing song’s store path after double switching on and off.
8. Can’t automatically skip through folders (under order play, it would skip to next sub-folder, if there is any, after it played all the files of the former folder).
9. Abnormal/Messy display of Korean characters when language is set as Simplified Chinese (Japanese characters are still ok)
10. Can only use FAT32 TF card to perform firmware upgrade
11. Can’t support the display of time and date.
12. Can’t delete the whole folder.
13. Can’t add the scroll bar to indicate the current location within the folder when choosing songs.
