About this guide

A slow keyboard is usually caused by the suggestion features working in the background, an outdated keyboard app or a full phone. The settings below are all on one page.

The screenshots are from a Samsung Galaxy A57 5G with One UI 8.5 and Android 16. Other Galaxy phones on One UI 8 use the same menus; on older One UI versions a few names and positions differ. We only looked at these screens on our phone and changed nothing.

Good to know

If only one app lags, update that app; the keyboard is rarely the cause then.

Lag across the whole phone points to low storage: how to check and free up storage on a Samsung Galaxy phone.

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