This guide will explore the causes, provide step-by-step solutions, and share relevant technical insights. ## My Personal Experience with the NFC Issue I vividly remember the panic I felt when my Samsung S20's NFC suddenly greyed out right before I was about to tap to pay for groceries. As someone who heavily relies on Google Pay and Samsung Pay, this was more than a minor inconvenience—it felt like losing a vital skill.
