THUMB for SCALE
I made a tool to fix my Moto X. a USB-C cable was not going into the port. it would start and then hang out. charging was problematic. sometimes it charmed. sometimes it charged. when a thing is fuxord you cannot fuxor it more. meaning? try to unfuxor it.
when I played iPod all the time I found that the headphone jack (remember those) would get lint on the inside. the plugging in ear bugs would hammer down the lint until the LEFT or was it RiGHT channel stopped. the fix was to tooth pick the goo from the hole.
