Anyone out there that has experience or knows of a video on how to open up a Samsung galaxy 2 from sprint to replace some parts. My phone is messing up, i think its the USB port where i charge my phone. . for some reason I get notification of MTP mount and charging cycles when my phone is not even connected to a USB cable and sometimes it tells me voltage to high. Has any one had this issues? Any videos on how to raplace the USB port??
