If your vivo phone has entered safe mode, you can try the following methods to remove it:
1.Restart your phone. Press and hold the power key on your vivo phone until the option to "Restart" appears on the screen, then select "Restart" and wait for the phone to restart.
2.Uninstall recently installed apps. Some apps may cause your phone to go into safe mode. Find "Settings" in the menu (usually the gear icon), then find the "Apps" option, select the recently installed apps, and try to uninstall them. If Safe Mode is off after uninstalling an app, there might be a problem with the app, and you can try reinstalling the app to see if it works.
3.Check that the battery and SIM card are well installed. Safe mode can be caused by a loose or failed battery or SIM card. Please turn off and reinstall the battery and SIM card, then restart your phone to see if it works.
4.Clear the cache partition. Sometimes, clearing the cache partition can also fix the problem. With your phone turned off, press and hold the volume key and the power key at the same time to enter fastboot mode. Then use the volume keys to select the "Clear Cache Partition" option and press the power key to confirm.
If you have tried the above methods and still cannot disable Safe Mode, then there may be other problems, it is recommended to contact vivo customer service or go to a repair center for help.
Hope the above information is helpful to you!
