Samsung Galaxy S8 Predictive Text: Turn It On or Off
If you want to turn predictive text on or off on a Samsung Galaxy S8 or Galaxy S8+, the setting is found in the Samsung Keyboard settings, under Smart typing. You can toggle it off entirely or disable specific features like personalized predictions and auto-replace.
Where the Setting Lives
On the Galaxy S8 and S8+, predictive text is a feature of the Samsung Keyboard, which is the default keyboard app. It is not a system-wide setting, so you change it within the keyboard’s own preferences. The exact path is: Settings > General Management > Language and Input > On-screen keyboard > Samsung Keyboard > Smart typing.
The Smart typing menu contains several related options. The main toggle is labeled Predictive text. When this is on, the keyboard suggests words as you type, and you can tap one to insert it. Turning this off disables the suggestion bar entirely, but other features like auto-correction and auto-replace may still work unless you disable them separately.
How Predictive Text Works on the S8
The predictive text engine on the Galaxy S8 learns from your typing habits. It builds a personal dictionary of words you use, including names, slang, and technical terms. When you type, it analyzes the current sentence and your past usage to offer three word suggestions above the keyboard. The middle suggestion is often the most likely next word, and tapping the space bar can insert it in many cases.
The system also uses context. For example, if you often type “I am going to the gym,” after typing “I am going to,” the keyboard might suggest “the” and then “gym” as the next word. This personalization is stored locally on the device, not in the cloud, unless you have enabled Samsung Cloud backup for keyboard data.
Step-by-Step: Turning Predictive Text Off
- Open the Settings app on your Galaxy S8 or S8+.
- Scroll down and tap General Management.
- Tap Language and Input.
- Tap On-screen keyboard.
- Tap Samsung Keyboard.
- Tap Smart typing.
- Tap the toggle next to Predictive text to turn it off (gray).
If you only want to stop the keyboard from learning new words, you can also turn off Personalized data in the same menu. This stops the keyboard from using your messages and typing history to make suggestions. You can also clear the learned data by tapping Clear personalized data.
Turning It Back On
To re-enable predictive text, follow the same path and tap the toggle next to Predictive text so it turns blue. The keyboard will immediately start showing suggestions again. If you had turned off personalized data, you may want to re-enable that as well to get the full benefit of learned words. Note that clearing personalized data is permanent—the keyboard will start learning from scratch.
Common Problems and Quick Fixes
Sometimes predictive text seems to stop working even when it is on. Here are a few things to check:
- Keyboard is not Samsung Keyboard: If you are using Gboard, SwiftKey, or another third-party keyboard, the Samsung settings will not affect it. Check which keyboard is active in Language and Input.
- Predictive text is on but no suggestions appear: This can happen if the keyboard is in a secure field like a password box. For security, Android disables suggestions in password fields. Try typing in a normal message field.
- Suggestions are wrong or irrelevant: The keyboard may have learned incorrect words from typos. Go to Smart typing > Clear personalized data to reset the learning.
- Auto-replace is causing errors: If the keyboard is changing words you typed correctly, turn off Auto replace in the same Smart typing menu. Keep Auto capitalize and Auto space on if you like those.
Predictive Text vs. Auto-Correct
Many users confuse predictive text with auto-correction, but they are separate features. Predictive text shows suggestions you can choose. Auto-correct automatically changes a word you type if it thinks it is a typo. On the Galaxy S8, both are under Smart typing but are independent toggles.
If you want to keep suggestions but stop the keyboard from changing your words, turn off Auto replace while leaving Predictive text on. If you want the keyboard to fix typos but not show suggestions, turn off Predictive text and leave Auto replace on. This is a common setup for people who find suggestions distracting but still want error correction.
Frequently Asked Questions
Why is predictive text not working on my S8?
First, make sure you are using the Samsung Keyboard, not a third-party keyboard. Then check that Predictive text is toggled on in Settings > General Management > Language and Input > On-screen keyboard > Samsung Keyboard > Smart typing. If it is on, try clearing personalized data, as corrupted learning data can sometimes cause the feature to malfunction. Also, remember that predictive text is disabled in password fields for security.
How do I clear the learned words on my Galaxy S8 keyboard?
Go to Settings > General Management > Language and Input > On-screen keyboard > Samsung Keyboard > Smart typing > Clear personalized data. Tap it and confirm. This removes all words the keyboard has learned from your typing history, but does not affect your contacts or messages. The keyboard will start learning again from scratch.
Can I turn off predictive text for just one app?
No, the Samsung Keyboard does not offer per-app settings for predictive text. The setting is global for all apps that use the Samsung Keyboard. If you need different behavior in different apps, you could switch to a third-party keyboard that supports per-app settings, such as Gboard or SwiftKey, but that is not a built-in feature on the S8.
Will turning off predictive text improve battery life?
The effect is negligible. Predictive text runs only when the keyboard is active, and the processing required is minimal. You will not notice a meaningful difference in battery life. If you are concerned about battery, focus on screen brightness, background apps, and connectivity settings instead.
How do I add a word to the S8 dictionary?
When you type a word that is not in the dictionary, the keyboard may underline it in red. Tap the word and then select “Add to dictionary” from the pop-up menu. Alternatively, you can go to Settings > General Management > Language and Input > On-screen keyboard > Samsung Keyboard > Smart typing > My dictionary, where you can manually add or delete words.
Does the S8 have a built-in swipe typing feature?
Yes, the Samsung Keyboard on the S8 supports swipe typing, which is called “Swipe to type” in the Smart typing settings. This is separate from predictive text. If you want to use swipe gestures, make sure that toggle is on. You can use swipe typing even if predictive text is off, but the suggestions bar will not appear.
