I just opened this phone and found something strange...

So I just opened my Samsung Galaxy GT-S7392 and found this empty port below the camera. Any ideas what this port is used for?

Here is a picture of the port:

It's marked M4121A9A

It is just on the side of that hole on the printed circuit board. Has anyone else seen such a connector in your phone?

Also, while opening it, I broke the USB port connection. Do you think I can charge my battery some other way now? (apart from using another Samsung device)

Possibly a diagnostic, testing or programming header, that's used during manufacture?

Hmmm... Yeah that can be the case but even then, if I get its datasheet then maybe I can use it with my PC or Arduino to do something cool?

I also think this can be a camera header because there is a hole next to it. My ASUS Zenfone 5 had the camera that way. Buy hey, the phone already got its camera somewhere else...
