How to solve the problem of forgetting the lock code of Android phone?

If the vivo phone you are using forgets the screen lock password, and the device is locked due to multiple password errors, we hope the following operations can help you.

When your device can still be unlocked into the desktop through fingerprints or faces, please back up the data on the device first.

Step 1: Confirm whether the password has been changed.

I suggest you think carefully about whether you have changed your password recently, or whether anyone who has been in contact with the device, such as family members or others, has changed your password.

Step 2: Confirm whether to use multi-user mode.

I suggest you check whether the user name or visitor is displayed in the lock screen interface. If it is displayed, it means that your device has turned on multi-user mode, and you can switch users to try to unlock it.

Step 3: Force the factory settings to be restored.

If the above operation still fails to solve the problem, it is recommended that you forcibly restore the factory settings of the equipment.

? This operation will erase all data from the device and cannot be recovered. It is recommended to back up the data before operation.

Backup: enter cloud service-device cloud backup-backup data type-system data-return-immediately back up some backup system settings and desktop layout; Cloud service-data synchronization-turn on WLAN and Bluetooth to synchronize data to cloud service.

1. Enter the recovery interface.

When the device is turned off, press and hold the "power button" and "volume up button" at the same time, and then release these two keys until the quick start interface is entered. Select the menu "Input Resume" by pressing the volume down button, and then press the power button to confirm the input.

Folding screen model: Please unfold the screen and follow the above method; NEX 3/3S series products: Please press and hold the top circle key 1-2 seconds in the closed state, and then press and hold the "volume increase key" to enter the quick start interface, and enter the recovery interface according to the page prompts.

2. Confirm to restore the factory settings.

Click "Clear Data > Clear All Data > OK" on the screen, wait for the operation to complete, and then return and restart the device. At this point, the device data and screen lock password have been cleared.

When the "Find Device" function is turned on for your device, you need to activate the device with the password of vivo account after the factory settings are forcibly restored. If you forget the password of vivo account, you can click on the webpage link to try to retrieve it.

Step 4: Go to the customer service center.

If the above methods fail to help the recovery, it needs to be detected and handled by the customer service center (customer service center address: go to vivo official website /vivo Mall APP—- My-service outlets/after-sales outlets-select provinces and cities to inquire about the customer service center address). It is suggested to call the customer service center in advance to confirm the relevant matters and know that the office hours are coming soon, so as not to delay precious time.

Tips:

1, some early models can reset the screen lock password through secret protection. When you enter the wrong password five times or more, click the "Forgotten Password" option on the screen to verify the answer to the secret security question, and then you can reset the password.

2. In order to protect personal data more effectively and avoid unexpected situations. It is recommended that you back up the equipment data in a timely and planned manner when using the equipment in the future. On the device, you can go to Settings > Account > Cloud Service and use the functions of "Cloud Backup" or "Data Synchronization" to back up the device data to the cloud. When restoring cloud data, you can click the "Restore Backup Data" area at the bottom of the "Cloud Backup" page to restore cloud data to the current device conveniently.
