If your phone is being monitored, it can lead to the leakage of personal information and financial security. Here are five ways to determine if your phone is being monitored:

1.If your own number connects directly, it indicates that your phone is being monitored.

2.If unfamiliar numbers appear in your contact list, it's likely due to illegal software.

3.The sudden appearance of a black screen also makes monitoring easier.

4.If your data usage and phone bills show abnormal increases, your phone may be monitored.

5.If you hear echoes or the call doesn't disconnect on its own, it could indicate that your phone is being monitored.

To protect your phone's security, it is recommended to use mobile security software and regularly scan for viruses to ensure the safety of your phone.
