Doing it this way is terrible, and for the most part worthless, unless the screen is already damaged.
The only safe way to replace the charging port is to desolder it and resolder a new one on. Otherwise...
Am I right in observing that the charging port flex module no longer has button ribbons that fold around the mid-frame and underneath the glass?
If so... techs everywhere are rejoicing right now.
Does anyone know what the little things on the inside of the housing along the edges do?
