Restrict App Downloads to Wi-Fi Only auf OnePlus
Large app updates and new installs can drain a mobile data plan within days if the Play Store is allowed to download over any network. Restricting downloads to Wi-Fi only puts you back in control of data usage on a OnePlus phone.
The setting responsible for this behavior lives inside the Play Store app itself, not in the system network settings. Open the path Open Play Store ➔ Open the menu ➔ Open the Settings ➔ Tap on App download preference ➔ Choose Over Wi-Fi only ➔ Confirm with Done to apply it.
Once active, the Play Store pauses any pending downloads or updates automatically when you leave a Wi-Fi network. They resume without further action as soon as the phone reconnects to Wi-Fi.
This setting is worth reverting temporarily if you need an app right away and only mobile data is available. Switching back to Over any network or Over Wi-Fi only using mobile data lets downloads continue, though large titles like games can still consume a significant chunk of your plan.
