Nothing kills the flow like a keyboard that refuses to show up, freezes mid sentence, or keeps crashing right when you need to reply. If your VIVO S1 Keyboard is not working, you are usually dealing with one of a few common causes: a stuck app process, corrupted cache, a conflicting third party app, low storage, or an input setting that silently changed after an update.
The good news is you can fix most keyboard issues in minutes without losing your photos or important data. Below is a practical, step by step guide you can follow on your VIVO S1, with quick wins first, deeper fixes later, and a few pro settings tweaks that make the problem less likely to come back.
What “keyboard not working” usually means on VIVO S1
On the VIVO S1 keyboard problems typically show up in one of these ways:
- The keyboard does not appear when you tap a text field
- The keyboard appears, but typing is delayed or laggy
- The keyboard closes instantly or shows “keeps stopping”
- Auto correct or suggestions behave strangely
- Swipe typing stops working
- The keyboard works in one app but not another
Most of the time, the keyboard app itself is fine. It is the keyboard’s temporary data, system resources, or app conflicts causing the chaos.
Quick Fix Checklist (do these first)
Before diving into settings, run through these fast actions. They solve a surprising number of cases.
- Restart your phone (a full restart, not just screen off)
- Switch to another app and try typing there (helps confirm if it is app specific)
- Toggle Airplane Mode on then off (sometimes helps if the keyboard is tied to voice typing or online suggestions)
- Free at least 1 to 2 GB storage (low space can cause apps to crash)
- Update the keyboard app and system software (bugs get patched)
If your vivo s1 keyboard is still acting up after this, move into the targeted fixes below.
VIVO S1 Keyboard settings: confirm the default keyboard is still selected
Sometimes after an update, installing a new keyboard, or restoring settings, the default input method changes quietly.
- Open Settings
- Go to System or System management (wording varies by region)
- Tap Languages and input
- Tap On screen keyboard or Virtual keyboard
- Make sure your preferred keyboard is enabled and selected as default
If you use Gboard and it disappeared from the list after an update, Google documents how to re enable it in Android settings.
Fix 1: Force stop the keyboard app and reopen it
When a keyboard process gets stuck, force stopping it clears the running state.
- Settings > Apps > App management
- Find your keyboard app (Gboard, vivo keyboard, or another)
- Tap Force stop
- Open any app (Messages or Notes) and tap a text field to relaunch the keyboard
This is the fastest “unstick” method and does not delete any personal data.
Fix 2: Clear keyboard cache (safe and usually effective)
Keyboard apps store temporary files to speed up suggestions and loading. When cache gets messy, crashes and lag become common. Google notes that Android lets you clear an app’s cache from Settings, and that settings can vary by device.
Steps on VIVO S1:
- Settings > Apps > App management
- Tap your keyboard app
- Tap Storage
- Tap Clear cache
- Reboot the phone
If the keyboard becomes slow the first time you open it after clearing cache, that is normal. Android explains that clearing cache deletes temporary data and can make apps slow on the next launch while they rebuild fresh files.
Fix 3: Clear keyboard storage (stronger reset)
If clearing cache did not work, clearing storage resets the keyboard app data. This can remove learned words, custom dictionaries, themes, and keyboard preferences, depending on the keyboard you use.
Do this only if the problem is ongoing:
- Settings > Apps > App management
- Choose the keyboard app
- Storage
- Tap Clear storage (or Clear data)
- Restart the phone
- Re enable the keyboard and set it as default again
Tip: If you use Gboard, your personal dictionary may sync with your Google account, but not always. Treat this as a clean reset.
Fix 4: Update Gboard or your keyboard app
If your VIVO S1 keyboard is third party (Gboard, SwiftKey, etc.), updating the app often fixes random crashes.
- Open Play Store
- Search the keyboard app
- Tap Update if available
Gboard is heavily maintained and widely used, including passing major download milestones on the Play Store, which usually correlates with frequent bug fixes and compatibility updates.
Fix 5: Check for system updates (Funtouch OS)
Keyboard stability can be affected by system level input services. Keeping your OS current matters, especially after a major app update.
- Settings > System update (or Software update)
- Download and install updates
You can also check official update resources through vivo support.
Fix 6: Fix “keyboard keeps stopping” with Safe Mode (find app conflicts)
If the keyboard crashes only after you installed a new app (launcher, cleaner, theme pack, emoji app, clipboard manager, VPN, accessibility tool), you may have an app conflict.
Safe Mode temporarily disables downloaded apps so you can test if the system behaves normally. Google’s Android Help explains using Safe Mode to find problem apps that cause freezing, crashing, or slowdowns.
How to test in Safe Mode
Typical method on many Android phones:
- Press and hold the Power button
- Press and hold Power off (or Restart) until Safe Mode prompt appears
- Confirm and reboot into Safe Mode
Exact steps can vary, but the idea is consistent: third party apps are disabled.
What to do once you are in Safe Mode
- Open Notes or Messages
- Tap a text box
- Test the keyboard for 2 to 3 minutes
If the keyboard works normally in Safe Mode, the cause is almost always a third party app conflict.
Remove the conflicting app
Back in normal mode, uninstall recent installs first, then retest. Start with:
- Keyboard theme apps
- Screen overlay apps
- Clipboard managers
- “Cleaner” or “boost” apps
- Automation apps
- Accessibility services you do not recognize
Fix 7: App specific keyboard issue (only one app is affected)
If your keyboard works everywhere except one app (for example WhatsApp or Instagram), the problem is usually the app itself.
Do this:
- Settings > Apps > choose the problematic app
- Tap Force stop
- Tap Storage > Clear cache
- Update the app from Play Store
- Reboot
If the app still breaks input fields, uninstall and reinstall the app. That forces a clean rebuild of its local configuration.
Fix 8: Disable overlays and accessibility services that can block input
Some apps draw over your screen or monitor input for features like bubbles, floating widgets, or screen filters. These can interfere with keyboard rendering.
Check these areas:
- Settings > Apps > Special app access > Display over other apps
- Settings > Accessibility
Turn off anything suspicious or unused, then test typing again.
Fix 9: Free up storage (yes, it matters for keyboards)
Keyboards look small, but they rely on system services, memory, and storage for language packs, predictions, and caching. When storage is extremely low, Android may aggressively kill background processes, which can cause “keeps stopping” loops.
A simple target is keeping a few gigabytes free. Android guidance on clearing temporary data highlights that cache builds over time and clearing it can help free space and improve performance.
Fast ways to free space:
- Delete large videos you do not need
- Clear cache of heavy apps (social apps and browsers)
- Remove unused apps
- Move photos to cloud storage (if you already use backup)
Fix 10: Reset app preferences (restores disabled system apps)
If a system component tied to input got disabled, resetting app preferences can bring it back without deleting your files.
Typical path:
- Settings > Apps > App management
- Tap the menu (three dots)
- Choose Reset app preferences
This restores defaults for disabled apps, notification restrictions, and permission limits. After doing this, revisit Languages and input and set your default keyboard again.
Fix 11: Reset all settings (does not delete photos, but resets system configuration)
When everything else fails, a settings reset fixes stubborn configuration issues that survive restarts.
On VIVO S1, “Reset all settings” is commonly available under system reset options.
What it can change:
- Wi Fi networks and Bluetooth pairings may need reconnecting
- Default apps may reset
- Display and sound preferences may revert
What it does not do:
- It does not wipe photos, videos, or downloads (factory reset is different)
After the reset, set your keyboard again and test.
Pro Tips: make your VIVO S1 keyboard smoother and more reliable
These are practical settings adjustments that help prevent future issues.
Turn off heavy features if your keyboard lags
If typing feels delayed, reduce features that require extra processing:
- Disable high intensity vibration
- Reduce animations
- Turn off fancy themes temporarily
- Disable real time suggestions if your keyboard offers it
Sometimes a lightweight setup is all it takes to stop lag.
Keep one keyboard enabled (avoid switching conflicts)
If you have three keyboard apps enabled, the system sometimes switches input methods unexpectedly, especially after updates. Keep only the one you actively use enabled, and disable the rest.
One handed mode can stop accidental closing
On some vivo models and Funtouch OS versions, one handed features exist at system level, and there is also a one handed mode in Gboard settings. vivo support references enabling one handed mode through Gboard preferences on supported models.
If your keyboard is getting dismissed because your thumb hits the edge or gesture area, one handed mode can stabilize typing.
Common causes and the best fix (quick table)
| Symptom on VIVO S1 | Most likely cause | Fastest fix |
|---|---|---|
| Keyboard does not show up anywhere | Default keyboard changed or keyboard disabled | Re select default keyboard in Languages and input |
| Keyboard crashes with “keeps stopping” | Corrupt cache or app conflict | Clear cache, then Safe Mode test |
| Keyboard works in some apps only | One app cache or bug | Clear app cache, update app |
| Typing is slow or delayed | Low storage, heavy features, background load | Free space, clear cache, reduce features |
| Keyboard disappears after update | Keyboard disabled after update | Re enable in On screen keyboard list |
FAQ: VIVO S1 Keyboard problems people ask about
Why is my VIVO S1 Keyboard not showing when I tap a text box?
Most often the default keyboard got switched, the keyboard app is disabled, or the app you are typing in is stuck. Fix it by re selecting the default keyboard, then force stop the keyboard app and clear cache.
Will clearing keyboard data delete my chats or notes?
No. Clearing keyboard data resets the keyboard app’s own settings and learned words. Your chats and notes remain in their apps. The main loss is personal dictionary and keyboard preferences.
What if the keyboard works in Safe Mode but not normally?
That points to a third party app conflict. Google’s Safe Mode guidance is designed specifically to identify apps causing crashing and slowdowns. Uninstall recent installs and retest after each removal.
Should I install a new keyboard app to fix this?
If your current keyboard keeps crashing even after cache and data resets, installing a well maintained keyboard can help. If you do that, enable only one keyboard at a time to avoid switching issues.
Real world scenario: the “it started after I installed an app” case
A common pattern looks like this:
- Keyboard worked fine for months
- A new “cleaner” app or theme app was installed
- Keyboard started freezing, then crashing
- Clearing cache helped for one day, then the issue returned
In cases like this, the keyboard is not the real problem. The interfering app is. Safe Mode confirms it fast, and removing the app resolves it for good. Google explicitly points to downloaded apps as a common source of crashes and slowdowns, which is exactly what this scenario matches.
Conclusion
A broken keyboard feels like a major phone problem, but on the VIVO S1 it is usually a fixable mix of settings, cache, storage pressure, or app conflicts. Start simple: confirm the default VIVO S1 Keyboard selection, force stop the keyboard app, then clear cache. If crashes continue, clear storage, update your apps and Funtouch OS, and use Safe Mode to identify conflicts. Once it is stable again, keeping only one keyboard enabled and maintaining free storage helps prevent repeat issues.
In the bigger picture, your phone’s typing experience depends on the same fundamentals as any virtual keyboard: smooth system resources, clean app data, and stable input settings.
