Will I be monitored when I make a phone call with OPPO?

Is the mobile phone listening or reading short messages?

1. Is the phone being monitored?

Mobile phone calls are all done on your device, and OPPO will not monitor your calls in any way.

2. Is the mobile phone information monitored?

OPPO will not monitor your information in any way. If you suspect that the APP has monitoring behavior, you can view and manage the microphone permissions in the settings or the "Mobile Manager" APP, and there will be an eye-catching reminder in the status bar when calling the microphone.

3. Have you seen the content of mobile phone chat?

Chat content belongs to personal privacy. It is strictly encrypted and cannot be viewed by others. If you suspect that the APP has reading behavior, you can view and manage SMS (information) permissions in the settings or the "Mobile Manager" APP.

4. Judge whether the mobile phone is monitored (monitored)

Mobile phones may be monitored under the following circumstances:

(1) After the mobile phone sends a short message or a call, check whether there are other suspicious short messages or call records.

(2) Generally, it is necessary to install a monitoring software to monitor the mobile phone, but the monitoring software is hidden and difficult to be detected. If you suspect that your mobile phone is being monitored, you can back up the necessary software and data on your mobile phone, and then restore your mobile phone to the factory settings, so that some unknown or potentially threatening software will be disposed of.

(3) the mobile phone is often stuck. For example, when entering QQ, WeChat, games and other pages, the phone will be stuck for a few seconds or the screen will be blank. It is useless to operate any button at this time, and it will return to normal after a few seconds. It doesn't matter if it happens once in a while, you should pay attention to it if it happens frequently.

(4) There are noises such as current sound when the mobile phone answers the phone. Generally speaking, there is no noise when the signal is stable. This situation may be that the mobile phone is being monitored at this time.

(5) When making a phone call, I was inexplicably hung up. When the signal was stable, I didn't touch the hang-up button and the other party didn't hang up, the phone suddenly stopped. This situation may be that there is a virus in the mobile phone or it is monitored.

(6) If the traffic and telephone charges suddenly increase sharply, it is recommended that you consult the operator for information.

(7) When there is an echo during the call, dial your mobile phone number again. Generally, you can't dial, which means you are on the phone. If you call, this situation may be that your mobile phone is being monitored.

If the above situation occurs, it is recommended that you:

(1) Clean up the mobile phone or mark strange numbers in the mobile phone in time.

(2) Uninstall suspicious applications.

(3) Turn off unnecessary sensitive permissions in the settings, such as microphones and cameras.

(4) Regularly enter the "Mobile Manager" APP for physical examination and optimization.
