smt710 works great, except for very slow charging. I get the slow charge warning all of the time now， I am sure it's not the cable or charger， My another Samsung device working very well With the cable and charger，only smt710！should i replace the charge board .
I tried many methods, including the method you gave me and online teaching, but none of these methods worked. I suspect the hardware interface or hardware resistance problem. Is it possible to replace the USB charging port expansion?
