Symptoms
- Power menu doesn't appear when holding the button
- Phone stays on despite selecting 'power off'
- Screen is unresponsive to the shutdown gesture
- Button seems to work for other functions like volume
Likely causes
- CommonSoftware freeze preventing the shutdown menu from respondingA frozen interface can block the normal power-off sequence from working.
- CommonAn app or process hung, blocking the system from processing the shutdown commandA misbehaving app can occupy the system enough to delay a response to shutdown.
- PossiblePhysical power button issueA stuck or unresponsive button can prevent the shutdown gesture from registering correctly.
- PossibleScreen digitizer issue preventing the on-screen slider from respondingIf the touchscreen has a fault, the shutdown slider may not register your touch.
What to do
- Try the standard power-off gesture again, holding the button(s) a bit longer than usual.
- If unresponsive, perform a forced restart using your phone's specific button combination.
- Once responsive again, check if a specific app was open when it froze and consider updating or uninstalling it.
- Test the power button's physical feel; it should click, not feel stuck or spongy.
- Test other touchscreen functions to see if unresponsiveness is limited to the shutdown screen or more widespread.
- Update the phone's software, since freeze-related bugs are commonly patched.
- If forced restart is needed every time you try to power off, that points to a deeper software or hardware issue.
When to call a pro
If the power button itself feels physically stuck or the touchscreen is unresponsive elsewhere too, have a repair shop check the hardware.
