I tried changing cables and the adapter but my S7 still won’t charge. I bought my S7 Edge for over a year now.
In many cases, the charging port is fine but has become clogged with debris. If your charging cable seems loose or falls out, try using a sharpened toothpick to gently clean gunk out of the charging port. You’ll probably be amazed at what comes out. After cleaning the port on my Galaxy S7, the charger worked like new again. Don’t use any moisture.
The hard way to fix this is to open up the phone and change the charge port. http://www.ebay.com/itm/OEM-USB-Dock-Cha… The easy way to fix is to purchase a Qi Wireless charger. No more cables. https://www.amazon.com/Choetech-T511-Wir…
It sounds like the charging port is not work, go to a repair shop to change a new one.
