After updating an Oppo device to the latest firmware, I’ve noticed that a few non-system apps are behaving inconsistently. System apps work fine, but some third-party apps either take too long to load or don’t refresh data unless the app is restarted.
One case I’ve seen is with finance-related apps. For example, when trying a FAB bank balance check, the app sometimes stays on a loading screen until background restrictions are disabled or battery optimization is adjusted.
I’ve already cleared cache and checked permissions, but I’m wondering if this is related to recent ColorOS background management changes or aggressive RAM control. Has anyone else faced similar behavior after flashing or updating Oppo software, and is there a recommended setting or fix that works consistently?
