You tap an app, and it freezes. You try to type a message, and the keyboard lags. Or perhaps, you have finally upgraded to the latest flagship device and need to wipe your old phone before handing it down to a sibling or selling it in Computer Village.
There comes a time in every smartphone’s life when a simple restart is not enough. You need the "nuclear option."
Learning how to do a factory reset on Android is a fundamental skill for any smartphone user. Whether you are battling a stubborn virus, trying to fix system glitches that appeared after an update, or preparing your device for a new owner, a factory reset returns your phone to the exact state it was in when you first unboxed it.
However, in 2026, resetting a phone is not as simple as just pressing a button. With advanced security features like Factory Reset Protection (FRP) and cloud-locked accounts, doing it wrong can turn your expensive device into a useless brick.
In this comprehensive guide, we will walk you through the safe, step-by-step methods for resetting any Android device—from Samsung and Google Pixel to Tecno and Infinix. We will also cover the critical pre-reset checklist to ensure you don’t lose your precious memories or get locked out of your own phone.
What Does a Factory Reset Actually Do?
Before we dive into the "how," let’s clarify the "what."
A Factory Data Reset (often called a "Hard Reset" or "Format") erases everything on your device's internal storage. This includes:
Google Accounts & Passwords.
System & App Data: All your settings, Wi-Fi passwords, and customizations.
Downloaded Apps: Every game and social media app you installed.
Personal Files: Music, photos, videos, and documents stored internally.
What it does NOT delete:
Data stored on your SD Card (unless you specifically select that option).
The Android Operating System itself (it simply reverts it to a clean state).
The Critical Pre-Reset Checklist (Do NOT Skip This)
If you rush into a reset without preparation, you will regret it. Follow these three steps to ensure a smooth transition.
1. Backup Your Data
Once you wipe the phone, the data is gone forever.
Photos: Ensure Google Photos has finished backing up.
Chats: Run a manual backup on WhatsApp (Settings > Chats > Chat Backup).
Contacts: Ensure your contacts are synced to your Google Account, not saved to the "Phone" storage.

2. Charge Your Battery
Ensure your phone has at least 50% battery life. If your phone dies in the middle of a factory reset, it can corrupt the operating system, "bricking" the device.
3. Remove Your Google Account (The FRP Trap)
This is the most important step for 2026. Android has a security feature called Factory Reset Protection (FRP). If you reset a phone while a Google Account is still signed in, the phone will demand the password for that specific email address upon reboot.
If you are selling the phone and forget this step, the new buyer cannot use it.
How to remove: Go to Settings > Passwords & Accounts (or Accounts and Backup). Tap your Google/Gmail account and select Remove Account.
Method 1: The Settings Menu (The "Soft" Reset)
This is the standard, safest, and easiest way to wipe your phone if you can still access the screen and navigate the menus. The steps vary slightly depending on your phone brand.
For Google Pixel & Stock Android (Motorola, Nokia)
Open Settings.
Scroll down and tap System.
Tap Reset options.
Select Erase all data (factory reset).
You will see a warning list of what will be deleted. Tap Erase all data.
Enter your PIN or Pattern to confirm.
Tap Erase all data one last time. The phone will reboot and begin the wiping process.
For Samsung Galaxy (One UI)
Samsung buries the option slightly deeper.
Open Settings.
Scroll down to General management.
Tap Reset.
Select Factory data reset.
Scroll to the bottom and tap the blue Reset button.
Enter your Samsung Account password (if prompted) and PIN.
Tap Delete all.
For Tecno, Infinix & Itel (HiOS / XOS)
Given the popularity of Transsion devices in Nigeria, here is the specific path:
Open Settings.
Scroll down to System.
Tap Reset Phone.
Select Erase all data.
Confirm your Pattern/PIN.
The device will restart and show the "X" logo while wiping.
Method 2: Recovery Mode (The "Hard" Reset)
What if you can’t get into Settings? Perhaps your phone is stuck in a "boot loop" (restarting constantly), the screen is unresponsive, or you have forgotten your lock screen password.
In this scenario, you need to use the hardware buttons to access the Android Recovery Menu.
Note: This method triggers FRP. Ensure you know the Google Account details previously used on the phone.
Step 1: Power Off the Device
Hold the power button until the phone turns off completely.
Step 2: Boot into Recovery
This combination varies by brand:
Samsung (Newer models): Connect the phone to a PC via USB cable. Hold Volume Up + Power Button simultaneously. Release the Power button when the Samsung logo appears but keep holding Volume Up.
Pixel / Tecno / Infinix: Hold Volume Up + Power Button. (Some older models use Volume Down).
Xiaomi: Hold Volume Up + Power Button.
Step 3: Navigate the Menu
Once a screen with code (usually black with small text) appears:
Touchscreen will not work. Use the Volume Down button to scroll down.
Highlight the option Wipe data/factory reset.
Press the Power Button to select it.
Step 4: Confirm the Wipe
The system will ask for confirmation (it might say "This cannot be undone").
Use Volume buttons to highlight Factory data reset or Yes.
Press the Power Button.
Step 5: Reboot
Once the text at the bottom says "Data wipe complete," ensure Reboot system now is highlighted and press the Power Button. Your phone will restart as if it were brand new.
Method 3: Remote Reset (For Lost/Stolen Phones)
If your phone has been stolen or lost, you can perform a factory reset remotely to protect your sensitive data (banking apps, private photos).
Requirements:
The phone must be turned on and connected to the internet.
You must have Find My Device enabled (it is usually on by default).
Steps:
Go to android.com/find on any browser.
Log in with your Google Account.
Select the lost device from the top menu.
Click Erase Device.
Confirm your choice.
Warning: Once you erase the device, you will no longer be able to track its location. Do this only if you are certain you cannot recover the phone.

Method 4: Using a USSD Code (The Secret Dialer Method)
For some devices, specifically older models or specific brands like Infinix and Tecno, you can trigger a reset using a dialer code.
Open your Phone app (Dialer).
Type *2767*3855#.
Warning: On supported devices, this command executes immediately without asking for confirmation. Only type this if you are absolutely ready to wipe everything.
Note: This method is less common in Android 14/15 devices due to security updates preventing accidental wipes.
Post-Reset: Setting Up Your Device
Once the reset is complete, your phone will reboot to the "Hello" or "Welcome" screen.
Connect to Wi-Fi: You will need internet access to verify your ownership.
Google Verification: If you didn't remove the account (Method 2), you will be asked to enter the email and password previously synced to the device.
Restore Backup: You will be given the option to "Copy apps & data." This is where you can pull your data back from the cloud or your old device.
Frequently Asked Questions (FAQ)
Q: Will a factory reset remove a virus?
A: Yes. A factory reset is the most effective way to remove stubborn malware, adware, or spyware. It wipes the system clean, deleting the malicious files hiding in your storage.
Q: Does a factory reset delete the operating system?
A: No. It restores the operating system to its original state. If you recently updated from Android 14 to 15, the phone will remain on Android 15 after the reset; it won't downgrade.
Q: I forgot my PIN and did a hard reset. Now I'm stuck on Google verification. What do I do?
A: You have triggered the FRP lock. You must enter the Google account details that were on the phone. If you don't know them, you cannot use the phone. There are third-party tools that claim to bypass this, but they are risky and often don't work on 2026 security patches. Your best bet is to recover your Google account via a browser.
Q: Will a reset delete data on my SIM card?
A: No. Contacts and messages saved strictly to the SIM card are safe. However, most modern smartphones save these to the internal storage by default, so assume they will be wiped unless you are sure.
