Another older repair I am getting around to post. This time it’s a Nexus 5 phone that acquired an interesting habit of getting stuck in a random reboot loop. One moment it’s working fine, next it’s stuck in a boot screen with Google logo, then buzzes and reboots to the same thing. After a bit of Googling around, I realized that the likely culprit is a power button getting stuck. To confirm, I’d smack it a bit and watch the phone exit reboot loop and work for a while. That smacking was satisfying but not sustainable if I wanted the thing to survive. So back to ebay we go. I suppose Mouser/Digikey were also an option if I felt like desoldering the original, measuring it and then combing through all similar parts to find the fit. Instead I let other people do that. Most sellers had an exact replacement switch, but one claimed a new and improved one. It also looked a bit better so for $2 shipped I grabbed one. The typical title for these is “4mm Power On /Off Volume Switch Button For LG Nexus 5 D820 D821 Optimus L4 E440”.
