How to Format Samsung S4

Your Samsung Galaxy S4 has become very slow. You are failing to find a solution to the problem, you decide to sell your phone. You must sell your S4 and would like to erase all data on the device memory? Do not worry, we are here to help.

With today’s guide, we will discover how to format Samsung S4 bringing Android to its original state and deleting all the files on your device. This way you can repair the software errors that led to instability and the slow pace of Android. This will erase all data from the phone’s memory. This is a important in the event of sale or transfer of the device so your data doesn’t get compromised.

The procedure is extremely simple to carry out. Before putting it into practice, make sure you have a backup copy of all your data and check that the online backup of Google Drive and Gmail are working.

Preparing the Device

There are at least a couple of steps that you should do before you you start the format. A malware scan of the system and a backup of all data stored on the device memory is needed.

Malware Scan

If you decide to format Samsung S4 because the device is too slow or your applications are constantly crashing, there is a chance, that the cause of these problems is a malware using some app downloaded from external sources than the Google Play store. If the root cause of your problems is really malware, can you fix the situation without having to resort to the device formatting.

Backup your Data

Another mandatory thing to do before formatting a smartphone is the creation of a backup copy of all data on the device’s memory.

To complete this work, you can turn to various solutions: there are applications that allow you to save apps, settings and data on your smartphone, or on a microSD card (the backups are then transferred to your PC so they aren’t lost during the phone formatting). There is official Samsung software that allow you to save data on your PC and then there are Google online services that allow you to save photos, videos, contacts and other important data online (in order to sync them automatically via the Gmail account).

As for the best app for backup, I strongly recommend you try out Titanium Backup that allows you to create complete backup apps, data and settings and then restore them in the same application. The only downside of Titanium Backup is that to fully exploit its potential you must own a rooted device.

The app was not found in the store. 🙁


If you have not yet rooted your S4, you can try the Easy Backup & Restore that does not require this procedure but it saves only SMS/MMS messages, calendar appointments, bookmarks, call log and contacts.

Prefer to use the Samsung official software? I don’t recommend that as it is a less powerful and flexible solution than apps like Titanium Backup.

Finally, go to the settings of Android (the gear icon located in the screen with the list of all the apps installed on your device) and make sure that the functions for synchronization of data online are all active. How? Simple. Select the voice Account and “tap” first on the Google logo and then to your Gmail address. Then verify that the “levers” related to contacts, calendar etc. They are all set to ON. Otherwise you should activate them.

As for the photos, the backup is performed by the Google Photos app that lets you store in Google Drive all the photos up to 16MP and videos with a maximum resolution of 1080p on Google Drive, for free and without limits. If you want to ensure that Google’s backup function is active, start the application, press on the hamburger icon placed on the top left and select Settings from the toolbar that appears sideways.

Then moved to backup and sync, make sure the “lever” located at the top right is set to ON and configure the setting upload size of High Quality. All synchronized data online will be automatically downloaded on your S4 when, after formatting, going to configure your Google account on your phone.

WhatsApp supports backup of conversations on Google Drive. If you use this messaging app, go to its settings and make sure the backup function is turned on (or you will lose all of your chats).

Formatting of the Samsung Galaxy S4

Now you can finally take action and format your Samsung Galaxy S4. Know that during the procedure will clear the contents of the smartphone’s memory but not that of the microSD card. To format the microSD also you have to go in the menu Settings> Storage> Format SD Card and push the button Format SD Card. You can also remove the card from the smartphone and put it back at the end of the formatting process, it is not important to the success of the operation.

You are about to sell your smartphone and you must avoid risking your data as anything can be traced back to the data that existed on the device memory.

Factory Reset

To reset Android using the standard procedure of the operating system, you must go in the settings of the phone (the gear icon located in the menu of the notifications or the list of apps installed on your device) and select items Accounts > Backup and restore from the screen that opens.

Then move to Factory data and press the Reset device and Delete All buttons and wait for the phone to be reset. Within seconds your S4 will reboot and you will get a brand-new phone.

Hard Reset

If you can not perform the standard procedure for the recovery of Android, you will need to enter the Recovery menu (software that runs outside of the operating system, so it works even when Android OS is broken) by performing the so-called hard reset of your smartphone. Again Android will be restored to its factory state, the internal memory of the device will be deleted while the data on the microSD will stay in place.

For formatting Samsung S4 via hard reset, you have to turn off your phone and restart it while pressing the Volume Up, Power and Home buttons. If you can not shut down your smartphone, take out the battery temporarily.

When you see the Recovery menu, use the Volume button – to move to the wipe data / factory reset item and press Power to select it. Then select the option yes – delete all user data , press the Power button again and wait for the Android reset procedure to be performed. It may take a few seconds.
