DM100 problems

[zhariks]

1. I've bought DM100 becaude of LDAC support. Now I try to connect my headphones, and it connects only at SBC. That is very low. I need at list aptx.
2. There is now possibility to add folder to playlist. I'm used to sort my music by folders, and I'd like to add it by folders. FIIO support that option, DM100 - doesn't. Could you add that option.
2. It is possible to remove unused categories in mobile app, but there is now such option in DM100 interface. Please add such option - it is a standart in all players.
3. I use English interface, but there are some Chineese words, and incorrect translations in some places.
4. There is an option to choose functions for FN button. But I don't understand, where this button is located

Another problem is with headphones connection. Dm100 connects headphones automatically only a few seconds after startup. If I turn on my headphones after DM100 started, they will not connect automatically. I have to go to "modes" each time, and connect them manually. It is not normal behaviour!
For example, when I turn on headphones or bluetooth speaker, they connect to my mobile phone automatically
Mobile app looks awfull. There is no option to choose language in it, so it starts in my system languge (Russian). But translation is sometimes not correct, sometimes texts are trunced or overlap each other. I understand, that Russian is not main language for you, and I agree to use English. But I don't have such option in the app. Please add it
