Set Default Keyboard Language auf Oppo
On Oppo phones running ColorOS, Gboard always opens with whichever language sits at the top of your keyboard language list. This has nothing to do with the app you are using or the language you typed last. The order is fixed in the keyboard settings, so if English is on top, English shows up first even after a full restart.
This becomes a problem once you regularly switch between two or three input languages. You end up tapping the language key every single time just to get back to the one you actually need most often.
To change which language opens first, go to Tap on Settings ➔ Tap on Additional settings ➔ Tap on Keyboard & input method ➔ Tap on Gboard ➔ Tap on Languages ➔ Tap on Edit ➔ Drag a Keyboard language to the first position.
Once the language you want is dragged to the top, Gboard opens with it by default in every app. You can still switch to your other installed languages with the usual language key on the keyboard, but you no longer start from the wrong one each time.
