Hello, i have a s7 edge. I bought a fast charger car charger phone my phone a few months back. It says qualcomm 2.0 on it. I used it for awhile but i noticed my phonenwould no longer fast charge (it would still charge at regular speed, just not fast charge). After failed diagnostic by Samsung and att i was sent out a replacment. I'm currently wondering if it could have been caused by the charger in my car changing it too fast. Thanks!
This is the charger i got from amazon
