Very aggravating issue, please bear with me:
Since doing the OTA upgrade from Android 6.0 to Android 6.0.1, my phone has not fast charged using any charging bricks or cables. Even if they are brand new. I was enrolled in the Samsung protection plus program, so I got a replacement phone because of the issue, and after the new phone automatically updated to 6.0.1 it also would no longer fast charge. However, when I first got the new phone it would fast charge by cable before updating to 6.0.1. It still fast charges wirelessly via the charging pad after the 6.0.1 update. Also, when I reinstalled Android 6.0 it would fast charge again via cable, but because Verizon pushes OTA updates when you're connected to wifi, my phone automatically updated to 6.0.1 and the fast charging problem immediately occurred again.
Does anybody else have this problem, and does anyone know of a way to fix it?
