What is the reason why vivo mobile phone automatically hangs up when answering the phone?

When the mobile phone automatically hangs up when making a call, it can be checked and handled according to the following methods:

1. If the phone is far away from the ear during the call, the phone will light up, and your finger or face may accidentally touch the hang-up button and hang up the phone.

2. If the mobile phone card is cut open by hand, the call may be interrupted due to irregular shape and poor contact. It is recommended to bring your personal ID card to the operator's business hall to apply for a standard mobile phone card. If the mobile phone card is dirty or oxidized, it will also lead to poor contact. It is recommended to keep the mobile phone card clean.

3. Poor cell phone signal may lead to call interruption. It is recommended to call in an area with good signal. If the call is interrupted in the same place, it may be caused by an abnormal network in this area. I suggest you try again somewhere else.

4. If the call duration reaches 1 or 2 hours on the hour, it may be limited by the operator, so it is recommended to consult the operator.

5. If the local 2/3G call network environment is not good, it is recommended to contact the operator to open VoLTE HD call service and try again. When the VoLTE function is turned on, the HD icon will be displayed in the signal bar.

6. If the call with the fixed person is interrupted, it may be that the other party's network signal is abnormal, or there is something wrong with the other party's calling equipment.

7. Please upgrade the system to the latest version before viewing.

8. Go to Settings-System Management-Backup and Reset-Reset Network Settings-Reset Settings, and then use View.

Note: the corresponding SIM card should be selected for dual cards; Resetting the network settings will delete and disconnect the connection and pairing records of WLAN, mobile data network, Bluetooth and other networks. Before operation, it is recommended to back up the data such as WiFi account number and password, and you can enter the cloud service-data synchronization-turn on WLAN and Bluetooth to synchronize the data to the cloud service; Go to Cloud Service-Device Cloud Backup-Backup Data Type-Open System Data-Return to the previous page-Back up immediately and back up some system setting data.

9. If there is no "Reset Network Settings" menu option on the mobile phone, you can enter Settings-System Management/More Settings-Backup and Reset/Restore Factory Settings-Restore All Settings-Restore. ?

Note: "Restore All Settings" will not delete any data or media files, but only restore all settings of the phone (such as setting wallpaper, unlocking method, WiFi, default opening program, desktop layout, etc.). ), some third-party application accounts need to log in again. Please ensure that the use of the software will not be affected before operation. For the sake of data security, it is recommended to back up the mobile phone data in advance before operation. (You can go to Cloud Service-Device Cloud Backup-Backup Data Type-System Data-Back-Back up some backup system settings and desktop layout immediately; Cloud service-data synchronization-enable WLAN, Bluetooth, etc. Synchronize data to cloud services)

10. If the above methods can't be solved, please back up the important data of the mobile phone in advance and take it to the vivo customer service center for testing and processing. (Address and contact telephone number of vivo customer service center: Go to the "vivo official website /vivo Mall" APP-My service outlet or click this link to enter and select the current city. )

Tips: It is recommended to bring relevant purchase vouchers (such as purchase invoices/warranty cards/ID cards) when you go, and call the service center staff in advance to ensure that the staff will go again during normal working hours, avoid running empty, and pay attention to safety on the way back and forth.
