Frequently asked questions
Will a hard reset delete everything on my vivo X21i?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the vivo X21i to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the vivo X21i remove the SIM lock or carrier lock?
No. A hard or factory reset only clears data and settings — it doesn't remove a carrier/SIM lock, which is tied to the device's IMEI at the network level. You'd need to contact your carrier for an unlock.
How long does a factory reset take on the vivo X21i?
Typically a few minutes, though it can take longer on older or heavily used devices as more stored data has to be wiped.
Will I need my Google account password after resetting the vivo X21i?
Yes, if Factory Reset Protection (FRP) is enabled. Android (and HarmonyOS 2.x devices with Google services) will ask for the last signed-in Google account after a reset — make sure you know that password first.
How do I reset my vivo X21i?
Use the Hard Reset method above if your vivo X21i is frozen or won't respond, or the Factory Reset method if the screen still works normally — both are covered step by step on this page.
How do I format my vivo X21i?
"Formatting" and "factory resetting" mean the same thing for the vivo X21i — both erase all data and restore default settings. Use whichever method above matches your situation.
Can I factory reset my vivo X21i without the password?
Yes — resetting through recovery mode doesn't require your lock screen password, since it bypasses the login screen entirely. That said, Factory Reset Protection may still ask for your Google account credentials afterward as an anti-theft measure.
