How to reset Samsung S4: Do you have to sell your Samsung Galaxy S4 but don’t know how to format it to remove all your personal data from the phone? Has your S4 started behaving strangely? Applications are crashing all the time and would you like to reset Android to fix the problem? No problem, you’ve come to the right place at the right time.

With today’s guide we will see how to reset samsung s4 – and therefore how to delete all the data on the smartphone memory – easily and securely. We will therefore see how to make a backup of all the data that will be deleted during the reset, both locally and on the cloud, and how to restore Android to the factory state by following two different procedures.

The first procedure is the standard one, which consists in returning Android to its factory state by acting directly from the operating system menu. The second one is related to the hard reset, which allows you to restart the smartphone in a forced manner and to reset Android through the Recovery. What is it about? Recovery is a software that acts outside the operating system – therefore outside Androiod – and allows you to format the phone even when for one reason or another Android does not start correctly. But now let’s not get too lost in chatting, choose the solution that seems to you best suited to your needs and put it into practice, find all the information you need right below.

Preliminary operations

Resetting a smartphone also means deleting all the data on its memory, so before proceeding I strongly recommend that you perform a backup of all your most important data. You can save data both locally and in the cloud, i.e. on the Internet. I suggest you do both.

Local backup

To make a backup of your data locally you have to use some applications suitable for the purpose, such as those I am about to recommend, and then you have to transfer the files obtained on a microSD or on the computer (so that they are not deleted too after the Android reset).

Among the best applications for backup on Android there are Titanium Backup And Easy Backup & Restore. They are both free, at least in their basic versions, but they have different functions. The first is much more complete, it manages to save everything: data, applications, settings, etc. but to work at 100% of its potential it needs root. The second app has fewer functions, it allows you to save only SMS, MMS, calendar, bookmarks, call log and address book, but it also works without the root. I explained how to use both in my tutorial on how to backup on Android.

Backup to the cloud

To save your data on the cloud you can take advantage of the synchronization services offered by Google for free, which should be active by default on your S4. Then go to the settings Android (the gear icon found in the list of apps installed on the mobile phone or in the notifications menu), select the item Account and “tap” first on the logo of Google and then on yours Gmail address.

At this point, check that the “levers” relating to the synchronization of contacts, calendar, etc. are all up ON And that’s it. If any “lever” is not active, move it up ON and wait for the data synchronization to complete.

As for photos and videos, you can take advantage of the application Google photo which allows you to store everything on Google Drive at no cost (as long as the photos do not have a resolution higher than 16MP and the videos a resolution higher than 1080p).

If you want to make sure that the photo and video backup function is active, open Google Photos, go to the menu settings pressing the ad icon Hamburger located at the top left and select the item Backup and synchronization. So check that the “lever” located at the top right is set to ON and configure the Upload size on High quality.

Other things to do

Other operations I recommend you do before resetting Android are the following.

  • Connect your S4 to your computer and make an additional data backup via the software Samsung Smart Switch. I explained how to use it in my guide on how to connect Samsung mobile to PC.
  • Make a backup of WhatsApp conversations following the instructions in my tutorial on how to save WhatsApp chats (operation to be carried out before creating a complete backup of the phone, otherwise with the Android reset the backup of the conversations will also be deleted).
  • Install an antivirus for Android and make one full scan. Perhaps your smartphone has been hit by malware and using such an application you may be able to “straighten out” the situation without resorting to a complete system reset.
  • Extract the microSD from your smartphone (if you are using one). Normally, the data on the microSD is not erased during an Android reset but, to be on the safe side, it is best to remove the drive from the device before taking action. If you want to intentionally format your microSD, go to the menu Settings> Storage> Format SD Card of Android and presses the button Format SD card: it’s very easy!

Factory data reset on Samsung S4

You are now officially ready for reset Samsung S4. Then go to the menu settings of Android (the gear icon found in the list of apps installed on the mobile phone or in the notifications menu), go to Account and select the item Backup and restore from the screen that opens.

At this point, select the item Factory data reset, presses the buttons Reset device and Delete everything and wait for the procedure to be completed. The smartphone will restart and when Android is restarted you will have to carry out the initial configuration procedure of the operating system again (the one in which to set the language, Wi-Fi connection, Google account and so on).

Hard Reset of Samsung S4

In the unfortunate when you fail to perform a factory data reset on your S4, you can reset the device by performing a hard reset. Then turn off the phone (if you can’t turn it off normally, take out the battery temporarily), then start it up and hold down the keys Volume +, Power And Home until the Recovery menu appears.

At this point, use the key Volume – to select the option wipe data / factory reset and press the button Power to access the recovery menu. So move on to the option yes – – delete all user data and select it with the key Power to start the actual Android reset.

Finally, select the option reboot system now to restart your smartphone and perform the Android initial setup procedure. Also in this case the data on the microSD are not deleted.

If you have any doubts regarding the Samsung Galaxy S4 hard reset procedure, you can connect to YouTube and look for a video tutorial dedicated to the topic, there are galore.

Note: if you are about to sell your smartphone and you want to be sure that your data is 100% unrecoverable, even using software for recovering deleted data, wiping the free space on your phone following the instructions you find in my guide on how format Android.

Reset Samsung S4 from the computer

How to reset Samsung S4

You have installed Smart Switch on the PC? Then know that you can take advantage of the potential of Samsung’s official software to reset your S4. All you have to do is turn off your smartphone and start it in Download Mode by holding down the key combination Power + Volume Down + Home for a few seconds, until an exclamation point appears in the center of the screen.

Next, press the key Volume up of the phone to access the main Download Mode screen, start Smart Switch on your PC and select the item Emergency software initialization and recovery from the menu Other located at the top right.

In the window that opens, select the tab Device initialization and type the model name of your smartphone in the appropriate text field. The model name is not the commercial name of the phone (Samsung Galaxy S4) but the technical name that you can find in the main screen of the Download Mode or in the data sheet of the device (it should be GT-I9505).

At this point, click on the button Near, type the serial number of your Galaxy S4 in the text field that appears below (you can also find this value in the Download Mode, or in the terminal package) and start the device initialization process by first clicking on Confirmation and then on OK twice in a row.

Finally, connect the phone to the PC using the supplied USB cable, press the button OK that appears in the center of the PC screen and Smart Switch will first download and then install the latest version of Android available for the smartphone. This could take several minutes.

At the end of the initialization you will have a “new” phone that you can configure by starting from scratch or by restoring a backup made previously with Smart Switch (or with one of the backup apps I mentioned earlier). It’s all a lot simpler than you imagined, right?

Note: Smart Switch only supports terminals with Android 4.3 or later. If you are using Android 4.2 and the device is not recognized by the program, update Android or use Samsung KIES, Samsung’s old official software for Windows and macOS.
