Factory resetting your Samsung Galaxy S26 is the most complete way to wipe it clean, returning it to the state it was in when you first took it out of the box. It's a powerful step for dealing with stubborn software bugs, preparing the phone for a new owner, or just getting a completely fresh start with the new One UI 8.5. Doing it correctly ensures you don't lose your data or get locked out by Factory Reset Protection.
Back Up Everything Before You Start
This step is non-negotiable. A factory reset will permanently delete all your apps, photos, messages, and settings from the phone's internal storage. Your first stop should be Settings > Accounts and backup. From here, you can back up to Samsung Cloud or to your Google Account.
For a more comprehensive backup, especially with a brand-new device like the S26, I'd recommend using Samsung's Smart Switch app on a Windows PC or Mac. It creates a complete image of your phone that's easy to restore. Double-check that your photos are safely synced to Google Photos or another cloud service before proceeding.
Remove Your Samsung and Google Accounts
To avoid Factory Reset Protection (FRP) locking the phone after the reset, you need to sign out of your main accounts. Go to Settings > Accounts and backup > Manage accounts. Tap on your Samsung account, then select Remove account. Do the same for your primary Google Account.
This tells the system you are intentionally resetting the device. If you skip this and the phone can't verify your identity after the wipe, you'll be completely locked out and will need your original login credentials to proceed, which can be a huge hassle.
Perform the Reset from Within Settings
This is the standard method when your phone is working normally. Open Settings and navigate to General management > Reset > Factory data reset. You'll see a detailed list of everything that will be erased, including apps, accounts, and personal files.
Scroll to the bottom and tap Reset. On the next screen, tap Delete all. You'll be asked to enter your PIN, pattern, or password for security confirmation. Once you do, the phone will restart and begin the erasure process, which can take several minutes. When it's done, you'll see the initial setup screen in One UI 8.5.
Use Recovery Mode If the Phone Is Frozen
If your Galaxy S26 is unresponsive, stuck in a boot loop, or won't start properly, you can force a reset using the hardware buttons. First, ensure the phone is turned off. Press and hold the Volume Down button and the Side/Power button together for about 10 seconds to force a restart. As soon as the screen goes black, release both buttons and immediately press and hold Volume Up and the Side/Power button.
Hold them until you see the Samsung logo, then release. This will boot you into the Android Recovery menu. Use the Volume buttons to highlight Wipe data/factory reset and press the Power button to select it. Confirm by selecting Factory data reset. Once it finishes, choose Reboot system now.
Try a Less Drastic Reset First
For issues like Wi-Fi or Bluetooth not connecting, or general system sluggishness, a full factory reset might be overkill. Go to Settings > General management > Reset. Here you'll find options to Reset network settings, which clears all saved Wi-Fi and Bluetooth connections, and Reset settings, which restores all system settings to default without touching your personal data.
Given that the S26 runs the new One UI 8.5, some early software bugs might be resolved by simply resetting all settings. It's a good middle-ground step before committing to the full wipe.
Restoring Your Phone After the Reset
After the reset completes, you'll walk through the standard Android setup. Connect to Wi-Fi and sign back into the Google and Samsung accounts you removed earlier. When you reach the restoration screen, you can choose to restore from the Samsung Cloud or Google Drive backup you made earlier.
This will reinstall your apps and bring back your call logs, messages, and device settings. Your photos will need to sync back down from your cloud service. Be patient, as downloading everything, especially on a fresh install of a new OS, can take a while.
When a Factory Reset Is the Right Call
With a new device like the S26, a factory reset is most useful for clearing out persistent early-adopter software glitches in One UI 8.5 that a simple restart doesn't fix. It's also the only way to fully sanitize the phone before selling it, ensuring none of your personal information remains.
For problems like severe battery drain, constant app crashes, or if you suspect malware, a reset can be the most effective solution. If you're troubleshooting, remember you can also clear the system cache from the Recovery Mode menu, which often fixes performance issues without deleting your data.
