A factory reset is one of the most useful and most mishandled things you can do with a phone. Done right, it wipes all your data, removes account locks, and leaves the phone ready for a new owner or a fresh start. Done wrong, it leaves your data accessible, the phone locked to your account, or both. Here is the complete process for 2026.
What changed in 2026
- Activation Lock and Factory Reset Protection are strictly enforced. Apple and Google both prevent activation of a wiped device if the previous owner's account was not removed first — a phone you buy secondhand that hits this wall is a paperweight.
- Encrypted storage is universal. iOS has been encrypted since iOS 8; Android has mandated encryption on new devices since Android 10. A factory reset destroys the encryption key, making recovery of wiped data practically impossible without forensic hardware.
- Cloud backup is faster. iCloud and Google One backups of a 128 GB phone typically complete in 5–15 minutes on a good Wi-Fi connection.
Before you reset: the checklist
| Step |
iPhone |
Android |
| Back up data |
iCloud backup or iTunes/Finder |
Google backup or manual to PC |
| Note your accounts |
Apple ID, email, authenticator apps |
Google account, 2FA apps |
| Sign out of apps |
Especially banking, authenticator |
Especially banking, authenticator |
| Turn off Find My / Find My Device |
Settings > [Your Name] > Find My |
Settings > Security > Find My Device |
| Remove SIM if selling |
Yes — keep your SIM |
Yes — keep your SIM |
Do not skip the Find My / Find My Device step. It is the #1 reason secondhand phones are bricked.
How to factory reset an iPhone
- Open Settings → [Your Name] → Sign Out. Enter your Apple ID password and tap Turn Off for any data you want to keep on iCloud.
- Confirm Find My iPhone is off: Settings → [Your Name] → Find My → Find My iPhone should show Off after sign-out.
- Go to Settings → General → Transfer or Reset iPhone → Erase All Content and Settings.
- Follow the prompts. iOS will back up again if you allow it, then erase. The process takes 2–5 minutes.
- The phone boots to the Setup screen (Hello). It is now completely wiped and unlocked from your Apple ID.
How to factory reset an Android phone
Android paths vary slightly by manufacturer, but the general flow is:
- Back up: Settings → System → Backup → Back up now (or Google One Backup).
- Turn off Find My Device: Settings → Security → Find My Device → toggle off.
- Reset: Settings → General Management (Samsung) or System (Pixel/stock Android) → Reset → Factory Data Reset.
- Tap Reset and confirm. Enter your PIN/password when prompted.
- The phone reboots, erases, and returns to the initial setup screen.
On Samsung devices, also remove your Samsung account: Settings → Accounts and backup → Manage accounts → Samsung account → Remove account.
Confirming the wipe is complete
After the reset, the setup wizard appears (language selection, Wi-Fi). This confirms the wipe worked. The phone should not ask for the previous owner's password at this point — if it does, Factory Reset Protection triggered, which means an account was not removed before wiping.
If you get a FRP screen after wiping, you need to sign in with the original account that was on the phone. There is no bypass that does not involve account credentials.
How to pick the right reset type
| Goal |
Method |
| Selling or giving away the phone |
Full factory reset + sign out of all accounts |
| Fixing software bugs on a phone you are keeping |
Factory reset, then restore from backup |
| Clearing a forgotten PIN |
Recovery mode reset (hold Power + Volume Down at boot) |
| Removing malware |
Factory reset; do not restore from an infected backup |
| Phone running slow |
Factory reset is the nuclear option; try clearing cache partition first |
Common mistakes
Resetting without backing up. Photos not in iCloud or Google Photos are gone permanently after a wipe.
Leaving Find My iPhone / Find My Device on. The next owner cannot set up the phone. You will get requests to unlock it.
Not removing authenticator apps from old devices. If you reset a phone with Google Authenticator and did not export your codes, you are locked out of all accounts using that app.
Assuming a reset destroys all data. Modern encrypted devices: yes, a reset is effectively permanent. Older unencrypted Android devices (pre-2019): some data recovery is possible. If that matters, use a secure erase tool after the reset.
What to skip
- Third-party "reset utility" apps — both iOS and Android have native resets that work better; third-party apps are unnecessary.
- Recovery mode resets before trying the settings reset — only go to recovery mode if the normal settings path is unavailable.
- Wiping a phone you plan to immediately restore just because it "feels slow" — often a restart, cache clear, or storage cleanup fixes performance without a full wipe.
FAQ
Will a factory reset remove a virus or malware?
Yes, in nearly all cases. A factory reset erases all app data including malware. Do not restore from a backup taken after the infection — start fresh and reinstall apps individually.
Can I recover data after a factory reset?
On modern encrypted phones (iOS 8+, Android 10+), recovery is practically impossible without the encryption key, which is destroyed on reset. Back up before wiping.
How long does a factory reset take?
2–5 minutes on most modern phones. The backup step beforehand takes 5–20 minutes depending on data volume and Wi-Fi speed.
Do I need to remove my SIM before a factory reset?
Not required for the reset to work, but recommended if selling the phone so you keep your phone number and contacts.
