With new Samsung devices constantly emerging, it's important to fully wipe your old phone before selling or donating it to protect your privacy. Many individuals are unaware that simple deletions don't completely clear Samsung devices, leaving deleted files in an invisible state. This article introduces the ultimate ways on how to delete everything on your phone Samsung, ensuring a 100% permanent deletion of all data on your phone.

Part 1: How to Delete Everything on Samsung by Factory Reset

Does a factory reset remove all data? Typically, a standard factory reset wipes all files but doesn't completely erase them. Hackers or a certain Android data recovery tool can potentially uncover and decrypt your sensitive data. By the way, a factory data reset on devices with external memory support will not remove data stored on an SD card.

* How to perform a factory reset on a powered-on Samsung device?

  • Navigate to the home screen on the Galaxy and choose "Apps".
  • From there, access "Settings" on the apps tab.
  • In the "Personal" section, opt for "Back up and reset".
  • Proceed to select "Factory data reset", followed by "Reset phone".
  • factory reset a samsung that is on

  • If prompted, input the current passcode or draw the unlock pattern.
  • Finally, select "Delete all". After that, consider setting up your device again.

Note: What's the difference between a hard reset and a factory reset on Samsung phone? A factory reset is done through Settings when the phone works normally. A hard reset is done using buttons (Recovery Mode) when the phone is frozen or won't boot. Both erase all data and trigger FRP if the Google account isn't removed.

 

Part 2: How to Erase Everything from Samsung via Recovery Mode

Recovery Mode on Samsung devices is a built-in system tool that allows users to perform maintenance tasks without fully booting into Android. It's especially useful when the phone is unresponsive, stuck, or locked.

* Perform a factory reset on a powered-off Samsung (Galaxy S8 and up):

  • Power off the phone (if no PIN is required). If you can't, let the battery drain until it shuts down.
  • Press and hold the "Bixby, Power, and Volume Up" buttons until the phone vibrates and the Samsung logo appears.
  • In Recovery Mode, use the Volume buttons to highlight "wipe data/factory reset" or Delete all user data, then press the "Power" button to select it.
  • factory reset a samsung that is off

  • Confirm by selecting "Yes" or "Factory data reset" with the "Volume and Power" buttons.
  • When you see "Data wipe complete", press the "Power" button to choose "Reboot device now".

* For Galaxy S7 and older:

  • Power off the phone.
  • Press and hold Volume Up + Home + Power buttons together.
  • Release when the Samsung logo appears.
  • In Recovery Mode, use Volume Down to select "Wipe data/factory reset" and press Power. (What if the recovery mode doesn't work?)
  • Confirm with "Yes". After reset, choose "Reboot system now".

Some data may remain after a reset, so for extra security, it's wise to encrypt your phone first. Go to Settings > Security > Encryption & credentials, select "Encrypt phone", then return to Settings to perform the reset.
