Step by step

Restart the phone
Samsung says to press and hold the Power key and tap Restart, or swipe down with two fingers and tap the power icon. On our Galaxy A57 the power menu shows Power off, Restart, Emergency call and Medical info.
Watch these steps Done
Check the default keyboard
Samsung's fix page says to make the preinstalled Samsung Keyboard the default, under General management, Keyboard list and default. On our Galaxy A57 with One UI 8.5 that row is just called Keyboard, and Default keyboard already said Samsung Keyboard.
Done
Go to the Samsung Keyboard page
Open Settings, General management and tap Samsung Keyboard settings. On our Galaxy A57 the row shows English (US) under its name. The Samsung Keyboard page opens, with Predictive text under Smart typing.
Done
Switch off the extra suggestions
On our Galaxy A57, Suggest emojis and Suggest stickers were both on. Switch them off, as in our screenshot, and try typing again. If the lag goes, leave them off.
Done
Test without Predictive text
Tap Predictive text. On our Galaxy A57 with One UI 8.5 the page has an English (US) switch, which was on, and Predict phrases, which was off. Switch English (US) off for a moment. If typing becomes smooth, leave it off, or switch it back on later to test again.
Done
Clear the keyboard's cache
Settings, Apps, Samsung Keyboard, Storage, Clear cache. If Samsung Keyboard is not in the Apps list, Samsung says to tap the sort icon and turn on Show system apps. Samsung's own fix goes on to Clear data, which also erases your keyboard settings and saved words, so try Clear cache first.
Done
Check for a keyboard update
At the bottom of the Samsung Keyboard page, tap About Samsung Keyboard, below Reset to default settings. The About page opens. On our Galaxy A57 it showed Version 5.9.30.61, the note A new version is available, and an Update button. We did not tap Update.
Done
Reset to default settings
Near the bottom of the Samsung Keyboard page, tap Reset to default settings, above About Samsung Keyboard. Use it last: it puts every keyboard setting back to the default.
Done

About this guide

Samsung's own fix for a lagging keyboard is a restart, the keyboard's cache and data, a software update and making Samsung Keyboard the default. We add the suggestion switches that sit on the same settings page. The fixes are in the order we would try them, quickest first.

We changed nothing on our phone except the two suggestion switches in step 4, which we switched off for the screenshot and back on straight after.

Good to know

If the whole phone is slow, not only the keyboard, check its storage: how to check and free up storage on a Samsung Galaxy phone.

In short: Restart; Samsung Keyboard as default; Samsung Keyboard settings: suggestions off, test Predictive text; clear cache; About Samsung Keyboard for an update; reset to default last.
