Frequently asked questions
Will a hard reset delete everything on my vivo S1 (China)?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the vivo S1 (China) to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the vivo S1 (China) 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 S1 (China)?
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 S1 (China)?
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 S1 (China)?
Use the Hard Reset method above if your vivo S1 (China) 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.
Does my vivo S1 (China) have a hard reset button?
Not a single dedicated button — the vivo S1 (China) uses a button combination instead of one labeled "reset." See the Hard Reset section above for the exact keys to press.
What is recovery mode on my vivo S1 (China)?
Recovery mode is a stripped-down menu outside the normal operating system, used to wipe data or apply updates when the vivo S1 (China) won't boot normally. See the Enter Recovery Mode section above for how to reach it on this device.
