It might have rubish wifi connection and buggy sideoaded apps. But when it comes to RFI and background noise, i have never heard a cleaner dap. This isthe first thing that i noticed when bought sp2000.Hi everyone, May I know when I'm charging my sp2000 and listen music together, I can here some electrical noise like"zip zip", escapically when I touch the screen to select music, the noise becomes louder, wonder it's normal or not? Thank you.
So i would say its faulty. Especially it happenes when you touch the screen. Otherwise i would suggest checking cable.
