Hello there,
I own a HA-P50SE and a Samsung Alpha phone running Android 4.4. They are connected with USB. Unfortunately, the Android phone drains the HA-P50SE, because it thinks that HA-P50SE is an external battery and use it to charge its internal battery.
I red on this topic that this is an Android OTG issue and Teac cannot fix it.
Do all Portable USB DAC with internal batteries have the same issue when they are connected to Android devices with USB ? If not, can you please list the products which don't have this "battery drain" issue ?
Thank you very much
Regards
