Myphone QTV20i No detection sa charging at USB done by replacing MT6223DA.
First kung ginawa replaced USB IO Port pero no luck. Malinis at ok naman ang v+ Line at ok din ang ground. I suspected na nasa MT6223DA ang sira which is processor at power management in one. So replaced ko na.
Ito na matapos ko mapalitan try ko na connect sa pc at nag charge na at ma detect nya na sa usb.
