Set Default Keyboard Language auf Realme
Gboard on Realme phones always opens with the language that sits first in your saved language list. If you added a second or third language later, it can end up above the one you actually use most, so every text field starts in the wrong language.
This has nothing to do with your regional or system language. It is a separate setting inside the keyboard app itself, and it only changes which language loads first when you tap into any input field.
To fix it, open Settings ➔ Additional settings ➔ Keyboard & input method ➔ Gboard ➔ Languages. Tap Edit to unlock reordering, then drag your preferred keyboard language to the first position in the list and confirm.
All other added languages stay available. You still switch to them with the usual language key or spacebar swipe, but the one you moved to the top now loads automatically every time you open a new text field.
If the wrong language keeps appearing even after reordering, check whether a second keyboard app is installed alongside Gboard. Only one keyboard app can be active at a time, and a different app might be set as the default input method instead.
