Recognizing Power Button Wear

The Power button on the Galaxy S25 Ultra undergoes hundreds of presses daily. Over time, it wears out, responds poorly to commands, or becomes stuck. The device refuses to turn on, shuts down without reason, or loops on startup: these signs indicate the internal mechanism is failing. A button that requires excessive pressure or sinks without response confirms it needs replacement.

Ignoring this defect makes things worse. A worn button can jam other internal components and eventually immobilize the phone completely. Changing the part quickly avoids a more costly repair and restores the device's original responsiveness.
