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.
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.
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.
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.
