1. I am having a similar issue with album art labeled cover.jpg. I tried to resize in photoshop to 800 x 800 and still the Mango OS will not recognize after a rescan. What is the file size limit in Mb?
==I am not sure of the max size for Mb and will have to check.
2. This is not an issue with the Android version of Mango which seems to have more options for display. Is the sound quality much different between the Mango OS and Android Mango?
3. When using the DX220 as a transport with optical out turned on using Chord DAVE DAC, there is a very annoying click sound when navigating through songs. This is not very noticeable on my other DAP (QP1R). There is no click/pop when songs play in album order gapless, only when navigating back and forth using optical out. This is also not noted when moving through songs on the internal DAC?
==We have checked this and it isn't our dac.
4. When in Android powering off gives definite feedback that powering down is occurring but when in the Mango OS, holding down power button just says good by but how do I know battery will not drain?
==The screen shows that it is powering off. A see you screen.
5. Is there a difference when scanning the SD card in Android vs Mango OS?
==There is no difference.
6. Does having WiFi turned in when using Mango OS drain the battery?
==There is no WiFi on Mango OS.
7. Why does the player get so hot with use? My other DAP is never even warm? Is this normal?
==It depends upon where the dap is, if you are playing hi resolution files and the load. The DX220 uses to desktop dac chips, they use more current than many dac chips. The more current the more heat produced.
8. Can the battery stay in charger after fully charged without damage? Trickle charge? Hard to time when charging over night.
==There is no damage with leaving the charger on.
9. One file doesn’t recognize the artist unless I search fir the name, then it comes up.
==I do not understand this question.
So far a great player. Just wish Mango OS had more options than Android version.
