There may come a time when you will have to reset your Samsung Galaxy S3. There are two different ways to do this, the hard reset and the soft reset, depending on what kind of problem you have with your device. If the problem is that it is frozen and doesn’t respond to commands then you’ll have to soft reset it, but if what’s wrong is that you’re having major problems that can’t be fixed with normal troubleshooting you’ll have to hard reset it to its factory defaults.
A soft reset will only reboot your device and then return you to the home screen, but if you hard reset your device you might have to re-install all of your applications.

Soft resetting your Samsung Galaxy S3


This is really very easy. You can either turn off your phone by holding the power button from 10 to 20 seconds and ten turn your device back on or follow these simple steps: First you turn off your phone and take out the back lid. Then you have to take out the battery, the MicroSD card, the MicroSIM and wait for a couple of minutes. After that put the MicroSD card back in, then the MicroSIM and the battery. Finally cover your phone with the back lid, turn the Galaxy S3 back on and let your phone start again.

Hard resetting your Samsung Galaxy S3

There are three ways to hard reset your Samsung Galaxy, using dial pad, from Android OS or from Startup. I would recommend you to save your data somewhere before you hard reset your device because the process will wipe it out. Also, if you have encrypted the data on your SD card you should disable encryption before these steps.

  • Reset using dial pad
    This is the recommended method for regular users, who do not have much knowledge about mobile OS systems. What you need to do is open the dial pad on your phone and enter: *2767*3855#
    After this, your Samsungn Galaxy S3 will reset itself. This is the simplest method to factory reset your S3.
  • Reset from Settings
    The first thing you have to do to hard reset your Android OS is to tap on settings, then you should go to back up and reset

    Once this is done you should tap on factory data reset

    After this you just have to reset the device and finally tap on reset everything.

  • Reset from Startup

    The first step is to press the volume up, Home, and Power buttons. You must hold all three buttons at once until the phone turns on.


    After this you will see the recovery screen, use the Volume Down button to go to wipe data/factory reset and you’re almost done.
    Finally, use the Home button to select the highlighted option.

        Hello, if I were you I’d contact the manufacturer. Tehere’s nothing else you can do.

      We are attempting a hard reset and get the options on screen. We scroll to wipe data/ factory reset but the home button will not select.
      Is there anything else we can do?

      • Mark 18/12/2012 at 00:11:05 Responder

        Get in touch with your manufacturer, there’s no other way to hard reset your Galaxy.

        Bonjour Lorris, this is a security matter you’ll have to check out with your mobile services provider.

      If i factory reset my galaxy s3do i have to unlock it again from t-mobile?

      • Helena 31/12/2012 at 00:22:46 Responder

        Hello Filip,
        No, you don’t. If you reset your handset, it will still be unlocked.

      I have hard reset my device. The screen u saw was the same as yr pic. It said it will not delete pics videos music etc but ive lost all mine by resetting. How can i get it all back?

      • Helena 31/12/2012 at 00:20:23 Responder

        Hi Briony,
        Unfortunately, you can’t get it back. If you saw the same screen, it means that all your data got deleted. You will need to download everything again. Good luck.

      hi, if i reset my phone, will i still get my old pictures, musics, messages but not the applications??

      • Helena 08/01/2013 at 00:09:34 Responder

        Hi Charissa,
        You will only lose your information if you hard reset it.

      Hi,my screen has been dented and i need to downlound aall my contacts,APPS etc but is there a SAMSUNG application i can get to put on my laptop

      • Mark 31/01/2013 at 02:37:57 Responder

        Hi David, there are a few ways to backup the Samsung Galaxy data on your laptop. You can use either the SD card and the Android card to backup your contacts and calendar, download the free Download SMS Backup + by Jan Berkel from the Android Market to save your SMS or MMS messages and call logs, download the Astro File Manager from the Android Market also for free to save your Market apps and use your SD card or your PC to save data. It’s all explained here.

        Thanks for contacting us and feel free to contact us with any query.

      can anyone advise me what i could do ??

      While I haven’t read the comments completely, I’m just going to point out that the hard reset instructions are completely wrong.

      Hold the Volume Up, Home, and Power Buttons at the same time.

      • Mark 14/02/2013 at 03:59:57 Responder

        Ok, thank you for telling me I’ve changed it.

        @Tom if you haven’t resolved the problem yet, just stop holding all three buttons and let it start itself up :)

      will doing a factory reset affect my external sd card’s contents even if i’ve removed it before doing the reset the hard way?

        Hi sseri. No, factory reset the hard way does not affect your external sd card’s contents.

      If i reset my sg3 (ATT) will it still be unlocked? or will i have to unlock it again so i can use other networks?

      • Helena 21/05/2013 at 23:46:38 Responder

        Emman, resetting and unlocking are different things, so you will probably need to unlock it after resetting.

      So if you soft reset your phone will you loose any data like apps app data pics contacts stuff like that?

      • Helena 03/06/2013 at 00:09:52 Responder

        No Philip, you’ll still keep those data. You will only lose them if you hard reset them
