I have a Samsung A13 phone that has been used, but have no PIN code. The phone is turned on, but locked. To reset the phone I need to shut it down, but to shut it down I need the PIN.

The battery is at 100%. I want to fix this before tomorrow. (I could turn on the flashlight, so I'm doing that to drain the battery.)

This unlockjournal about the A13 mentions that I repeat entering the PIN to get alternative options to unlock the phone. The only thing that happens is that I get a 30 second time out.


As @Robert suggested, I could restart the phone after holding Power + Volume Up + Volume Down for about half a minute. Then I could restart in Boot menu while holding Power + Volume Up. Then I did a factory reset and rebooted.

Guess what! The PIN is still needed, so this is not a reset to factory settings. Wiping the cache partition didn't make a difference.

Samsung knows the phone and expects an ID of some kind. It offers the option to login using a previously used Google account, but what if that is not possible?


How do I reset the PIN?

    Next to every Android phone can be forced to reboot by pressing and holding the power button for 10-60 seconds.

  • That worked with all three buttons pressed, but still I cannot reset the PIN. See my update.

  • How did the device enter this "PIN required" state? Where do you got the phone from? How long do you have the phone?

  • Phone is used by a colleague who is unavailable. The PIN he gave me doesn't work. I cannot use his account or reset his password to use his account to login to the phone.

The process to reset an A13 is extremely finicky. The timing matters.

  • Press VOL DOWN + POWER and hold for exactly 10 seconds
  • While keeping POWER held down, release VOL DOWN and and hold VOL UP
  • When the Samsung logo appears, immediately release both POWER and VOL UP

If this process doesn't work, connect the phone to a USB C power source and try again.

  • Pressing all three buttons and keep them pressed until the phone restarts.
  • At restart press the Power + Volume Up buttons and keep them pressed.
  • You enter the boot menu, where you can choose to reset to factory settings.
  • Complete the reset by rebooting.


The account has 2FA with Yubikey/Webauthn. When I log in, I press the key against the back of the phone, and I see a checkmark that the key is recognized and accepted. I then remove the key, after which the login is rejected.

It turns out that I need to keep pressing the key to the back, until a redirect follows and the login is completed. Apparently Google says the login is accepted before it is actually accepted.

  • I have a Samsung A51 and this doesn't work for me. Just reboots as normal, even if I do those button combinations.

  • This method is not working on my A13. It just reboots.
