Set Default Browser App auf Oppo
Oppo phones ship with Chrome pre-installed and set as the system default for opening links. Installing another browser does not change that automatically. Android keeps using the app registered as the default handler until you switch it manually in the system settings.
This matters because every link you tap in messages, emails, or other apps gets passed to whichever browser is set as default. If that is not the app you actually want, you end up opening the correct link in the wrong browser every time and have to copy it over manually.
How to switch the default browser
Open Tap on Settings ➔ Tap on App management ➔ Tap on Default apps ➔ Tap on Browser app ➔ Set the Default browser app. Select the browser you want to use going forward and confirm the choice.
Once set, the system routes all outgoing links through the new default browser immediately, without needing a restart. If the browser you want to use does not appear in the list, install it from the app store first, then repeat these steps.
