Frequently asked questions
Will a hard reset delete everything on my vivo Y21s?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the vivo Y21s to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the vivo Y21s 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 Y21s?
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 Y21s?
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 Y21s?
Use the Hard Reset method above if your vivo Y21s 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 Y21s?
"Formatting" and "factory resetting" mean the same thing for the vivo Y21s — both erase all data and restore default settings. Use whichever method above matches your situation.
Can I factory reset my vivo Y21s 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.
