Check these first
Do not assume the cause from the symptom alone. First determine whether the issue affects the whole phone, one app, one connection, or one accessory. Work from low-impact checks toward recovery or repair.
- Test a text field in another app
- Check for a connected Bluetooth or USB keyboard
- Make sure voice or handwriting input has not replaced the normal keyboard
Narrow down the cause
| Scope of the issue | Where to check next |
|---|---|
| Only one app is affected | Check app permissions, updates, storage, cache, and reinstall options |
| The whole phone is affected | Check restart, system updates, free storage, and system settings |
| Other devices have the same issue | Check the network, service, charger, or accessory |
| The issue began after a drop or liquid exposure | Avoid repeated power or charging attempts and contact official support |

Safe step-by-step process
Complete one step at a time and test after each change. Do not change several settings at once.
- 1Tap the text field again and look for the keyboard or input-method switcher near the bottom of the screen.
- 2Temporarily turn off Bluetooth and disconnect any physical keyboard.
- 3Close and reopen the app, then compare typing in a built-in notes or search app.
- 4Open keyboard and language settings and select one trusted default keyboard.
- 5Restart the phone and update the keyboard app and OS. On Android, clear keyboard cache if supported.
- 6Before reinstalling a keyboard, confirm whether personal dictionary, clipboard history, themes, or custom settings will be removed.
Actions to avoid
- Granting a keyboard from an unknown developer access to passwords or sensitive text
- Removing several input methods at the same time
- Force-closing an app before saving an important draft
Prevent the issue from returning
- Keep only trusted keyboards enabled
- Save long drafts regularly while typing
Frequently asked questions

Menu names and locations vary by OS, manufacturer, model, region, and software version. Use the Settings search field and check the manufacturer guide for your exact model.
When should I stop troubleshooting?
Stop as soon as the issue is fixed. Change one setting at a time so you can identify what solved the problem and reverse it if necessary.
What should I do if the issue remains?
Record how to reproduce it, verify your backup, and contact the manufacturer, carrier, or app provider most closely related to the problem.
