App Download Preference (Wi-Fi or Mobile Data) auf Oppo
By default, the Google Play Store on Oppo phones only fetches app downloads and updates when the device is connected to Wi-Fi. This protects your mobile data plan, but it also means an install can simply stall if Wi-Fi drops out or is not available.
This behavior comes from a setting inside the Play Store app, not from a Coloros system option. Changing it affects every app you install or update afterward, until you change the setting again.
Change the app download preference
Open Play Store ➔ tap your Google account icon ➔ go to Settings ➔ Network preferences ➔ App download preference. Pick an option and confirm with Done.
You get three choices: downloads over Wi-Fi only, downloads over any network including mobile data, or a prompt asking you each time a download would use mobile data. The prompt option is useful if your data plan is limited but you still want the flexibility to download over cellular occasionally.
If you allow downloads over mobile data at all times, large app updates can consume noticeable amounts of data, especially with automatic updates enabled. Stick to Wi-Fi only if your plan has a low data cap, or use the prompt option to decide case by case.
