If You Can’t Open Your Banking App with Trend Micro Mobile Security

You might see error messages when trying to open your banking app, like:

  • A6940: Device Security Compromised – the app found suspicious background activity.
  • A670: Disable Developer Options – Developer Options is turned on. Banking apps use extra security checks and may block access if they see Developer Options, strange background activity, or if the device is rooted, changed, or jailbroken.

Why Did This Happen?

These problems can happen because of:

  • Turning on Developer Options, which can cause issues with banking app security.
  • Security settings in Mobile Security that protect against suspicious activity.
  • Unusual activity that may suggest a security threat.
