3. "Monitor/Verify ADB Installation" or "USB Security/Verify Installation" type options — Must Disable
   • Function: Some manufacturers perform additional verification or interception for installations pushed via ADB, causing installation and authorization failures.
   • Operation: Disable items like "Verify apps over USB installation", "Monitor ADB installation", etc., to avoid installation or authorization being blocked.
