Why Your New OPPO Phone Won’t Work with Banking Apps
If your newly purchased OPPO phone keeps crashing or flashing back when opening bank-related apps, or you’re seeing messages suggesting the device is unprotected, the issue is likely related to USB debugging and developer settings being enabled.
Why Wont Banking Apps Work on New OPPO Phone
Most banking apps have built-in security mechanisms that detect whether a device is operating in a potentially unsafe state. If USB debugging is turned on, the system may interpret your phone as insecure, preventing the banking app from running properly to protect your financial data.
How to Fix this Issue
You can resolve this issue by disabling Developer Options and USB Debugging:
Step 1: Enable Developer Options (if not already enabled)
Go to [Settings] > [About device] > [Version]
Tap [Version number] seven times until you see a message that Developer Mode has been enabled.
Step 2: Turn Off USB Debugging
Navigate to [Settings] > [System & updates] > [Developer options]
Find and toggle off [USB debugging]
Then toggle off [Developer options] entirely.
Once disabled, banking apps should stop crashing and function as intended.
Tips for Mobile Security
Only enable Developer Options when absolutely necessary (e.g., for app development or advanced troubleshooting).
Most banking apps will flag any security feature that could potentially expose sensitive data—always disable these before use.
