TIMA prevents unauthorized module loading notifications
If an unauthorized module attempts to load the file, you can see the following notifications:
"Your mobile phone security has blocked unauthorized operations. No further action is required ."
• This notification is displayed if you have installed malicious application software or viruses and they attempt to install Linux core modules or modify the file system.
• Another reason for this notification is that you may have modified the file system of the device. The Linux core module is blocked and does not threaten the integrity of the device core. You may also need to check for malware or viruses on your device.
Disable "Android security enhancement" for TIMA detection"
• If you have installed a malicious application software or virus that modifies the Linux core data structure, the following notifications will appear.
• Another reason is that you may have modified the core of the device.
Restart the device to restore the "Android security enhancement" settings to normal. However, this does not solve the problem of "Android security enhancement" being disabled. We recommend that you check for malware, viruses, and malware.
TIMA detected unauthorized core changes
If the device's security system detects that the Linux core code has been modified after the device is turned on, the following notification is displayed.
The reasons for this notification are as follows:
• You have installed a malicious application software or virus that modifies the core code or file system.
