How do I fix an Android keyboard that won't show?
Steps to check
Restart the phone
A stuck input method often clears after a restart. Open a messaging app afterward to test.
Check default keyboard
Settings → System → Languages & input → On-screen keyboard (wording varies). Enable Gboard or your OEM keyboard and set it as default.
Samsung Settings → General management → Samsung Keyboard settings / Default keyboardPixel Settings → System → Languages & input → On-screen keyboardClear Gboard cache
Settings → Apps → Gboard → Storage → Clear cache. Avoid Clear data unless you're okay losing dictionary customizations.
Re-enable or reinstall the keyboard app
If the keyboard app was disabled, enable it. Reinstall from Play Store only after the steps above.
Common questions
Can I use another keyboard while troubleshooting?
Yes. Enable a second keyboard in Languages & input before disabling the broken one so you aren't locked out of typing.
