Been having issues with my s7. It’s ten months old and wouldn’t hold a charge. I sent it for repair and they said the USB port is damaged and it isnt covered by warranty. Ridiculous. The USB port 100% failed due to their poor quality as I never did anything beyond normal plugging the charger into it. I wasnt rough with it at all. The quote is over £200.
My gf had similar issues with her s4, I shouldve known better.
