Samsung Keyboard Keeps Stopping? Fix the Crash Loop

When Samsung Keyboard keeps stopping in a loop, every text field throws the “Samsung Keyboard has stopped” popup the second you tap it. We hit this on a Galaxy S24 running One UI 6.1 right after an update, and clearing the cache before the data ended it without wiping our saved words. This guide stays on the repeating crash loop and its One UI causes.

#Why Does My Samsung Keyboard Keep Stopping?

A repeating crash means the Samsung Keyboard service fails every time Android tries to load it. That’s different from a one-off glitch.

A corrupt cache is the most frequent trigger. The keyboard stores predictions, custom words, and theme data locally, and a half-written file after an interrupted update can crash the app the instant it tries to launch into a text field.

One UI updates are the second cause. The timing is the tell: if the loop started the same day your phone updated, a version mismatch between the keyboard and the new firmware is the likely reason.

A Good Lock module is the cause people miss. Keyboard themes installed through Good Lock change how Samsung Keyboard renders, and a theme that hasn’t been updated for your One UI version can force the app to crash on every launch. Our loop on the S24 stopped only after we removed a third-party Keys Cafe theme.

A faulty downloaded app is the last common cause. Clipboard managers, accessibility tools, and rival keyboards can grab the input service and break it. This guide stays scoped to the keeps-stopping loop. For the broader method dump plus the recovery-mode and factory-reset paths, see our companion guide on the Samsung Keyboard Has Stopped error.

#Clear the Cache, Then the Data, in That Order

Order matters here, and it’s the part most lists get wrong. Clear the cache first.

Why first? The cache alone is corrupt in many loops, and clearing it keeps your dictionary. Open Settings > Apps, search for Samsung Keyboard, tap Storage, then tap Clear Cache. In our testing on the Galaxy S24, clearing only the cache stopped the popup in under a minute and left our saved words intact.

If the loop continues, return to the same Storage screen and tap Clear Data. This resets the keyboard fully and does fix stubborn loops, but it erases your custom dictionary and learned predictions, which rebuild as you type. Reboot after either step to reload the input service, then test a few text fields to confirm the popup is gone for good.

If the phone won’t boot cleanly afterward, a Samsung black screen points to a deeper issue.

#Update the Software to Close Version Bugs

If the crash loop began after an update, the fix is often another update. According to Samsung’s keyboard troubleshooting steps, Force stop and Clear data is the documented first response to a misbehaving keyboard, and pairing that with current firmware closes most version-mismatch loops.

Go to Settings > Software Update and tap Download and Install. Also check the Galaxy Store for a separate Samsung Keyboard app update. Samsung’s guidance on updating Galaxy software confirms that installing the latest version clears crashes left from older builds, which is why an update-triggered loop usually ends after the next patch lands on your device.

#Set a Default Keyboard So You Can Keep Typing

Keep typing while Samsung Keyboard is down by switching to Gboard. Install it, open Settings > General Management > Keyboard List and Default, enable Gboard, and tap Default Keyboard.

Google’s Gboard support page confirms that it runs on every Android device on version 6.0 and later, so it’s a safe stopgap. On our Galaxy S24 the swap took about 20 seconds and let us keep texting through the repair. Switch back to Samsung Keyboard once the loop is gone.

#Is Good Lock or a Theme Causing It?

This is the One UI culprit that earns its own check. Good Lock and its Keys Cafe module let you build custom keyboard themes, and a theme that predates your current One UI version can crash Samsung Keyboard on launch.

Open Good Lock, go to Keys Cafe, and switch the active keyboard back to the default Samsung theme. If Good Lock won’t open, go to Settings > Apps > Keys Cafe > Storage and tap Clear Data to drop the custom theme. Test a text field right after. If the loop stops the moment you revert to stock, the theme was the cause.

On our Galaxy S24, reverting the theme ended a loop that survived two cache wipes. You can rebuild the theme once Keys Cafe gets an update for your One UI build.

A standalone keyboard theme from the Galaxy Store can do the same thing without Good Lock, so remove any recently added theme and retest with the stock look first. While you’re auditing storage, a bloated keyboard folder can also surface as Other storage on Samsung, worth clearing if your phone is tight on space.

#Test Safe Mode and Watch for Update Bugs

Reach for Safe Mode when the cache wipe, the update, and the Good Lock revert all fail. Safe Mode boots Android with only built-in apps. That isolates whether a downloaded app is the trigger, since nothing you installed runs in this mode and the keyboard either crashes or behaves normally.

Press and hold the Side Key and Volume Down, then long-press Power Off until the Safe Mode prompt appears, and tap it. If the keyboard works in Safe Mode, an app is the culprit.

Restart normally to exit, then uninstall recent apps one at a time, starting with clipboard managers, rival keyboards, and accessibility tools. Test after each removal so you can name the offender instead of guessing.

If the keyboard still crashes even in Safe Mode, the cause is system-level rather than an app. Wide One UI rollouts ship with rough edges, and keyboard crashes have shown up among the wider One UI 8 problems reported after major updates. Hold off on a factory reset until a pending patch lands. A separate Samsung service crash like com.samsung.android.incallui follows the same cache-then-update logic if other built-in apps start failing too.

#Bottom Line

Clear the Samsung Keyboard cache, then its data, and restart the phone first; that ends most keeps-stopping loops while protecting your saved words on the cache-only pass. If the loop started after a One UI update, install the latest patch and disable any Good Lock keyboard theme, the culprit most fix lists never mention. Test in Safe Mode to rule out a downloaded app before you ever consider a factory reset.
