I guys, today I tried to Wireless Charge while using the USB-OTG to copy some files (practically, it makes sense for me, since there is no need to connect the cable to the Nexus, we could be using that port to USB-OTG and charge at the same time).
I was surprised when it didn't work. I can't understand why would they implement this. Since it's not charging from cable, it could be charging by wireless...

It's not a defect from mine, right?

Anyway, thanks for your attention.

It's not a defect. You need a custom kernel that supports Qi Charging while using USB OTG if you want that.

Are you sure it's a kernel limitation? Do you know any that supports it?

May not be a hardware limitation. But probably a very low priority for implementation

One way I've try to offset this limitation is to plug my OTG cable into a powered USB hub. All attached USB devices use the hub for power greatly reducing the battery drain on the phone/tablet.
