When connected - no reaction in Win7
But succefully connected to Android via BT.
Battery doesn't charges. Leaks about 0.001V per second
At PCB find a little heating chip R32CF near battery socket. It heating when USB switched. Temp about 3-4 degrees higher than PCB.
Without USB connection all cold.
What is this? Is it the same like M324P at JDM-020?
Can't find any info about it in Internet
