Guys I'm having a small problem here. It seems like when i switch songs from the directory under the mango mode, the volume goes back to zero. Well i know it's not a big issue but because it takes a lot of turns from 0 to 70 which is my normal loudness... it could be quite troublesome especially when the leather casing is quite hindering the way to turn the knob. Just wanted to shout out to see who has this problem and found a solution to that. Oh... this only happened after I've updated to latest firmware last night.
