How to format S3: Is your Samsung Galaxy S3 getting slower and slower? Are applications crashing all the time? Tell me, have you already tried to scan the system with a good antivirus for Android? If the answer is yes but unfortunately the situation of the smartphone has not improved, I’m sorry, but I’m afraid that the only solution left to you is an Android reset.
By resetting Android, that is, by returning the system to the factory state, you will remove all the problems that have led the performance of the device to degrade in such an important way (assuming that it is a software problem and not a hardware one). I know, this is quite a drastic measure, but again, it is probably the simplest and most effective solution you can resort to.
The procedure to follow is quite simple, the times to put it into practice are quite limited, but you have to prepare yourself well. Resetting Android involves deleting all data and applications on the smartphone’s internal memory, this means before format S3 you need to take a few minutes of free time and make backups of all your most important data: emails, contacts, photos, videos, etc. Now I’ll tell you how to do it right away.
Preliminary operations: data backup
Before going to work and formatting your Samsung Galaxy S3, make a backup of all your data.
The backup can take place both locally (i.e. on the computer, on the smartphone memory or on an external microSD) and online. I advise you to take advantage of both solutions, so you will have your data stored in a safe place and you can synchronize contacts, calendars, photos, etc. online using Google’s free services.
To make a backup your data locally you can use various applications. I’ll immediately point out a couple of the best.
- Titanium Backup – if you have unlocked your smartphone via root I suggest you try Titanium Backup, a backup application that allows you to save applications, data and settings and restore them with a simple “tap”. The data can be saved directly on the phone memory or on an external microSD. The application is free but is also available in a paid Pro version which costs € 5.99 and includes some additional features (eg support for cloud storage services and backup encryption).
- Easy Backup & Restore – if you have not rooted on Android you can rely on the Easy Backup & Restore application, which offers fewer functions than Titanium but is just as valid. It allows you to create a backup copy of SMS, MMS, call log, calendar, bookmarks, and address book. All free. If you want to know more in detail how to make a backup on Android with Titanium Backup or Easy Backup & Restore, read my tutorial dedicated to the subject.
Caution: the backups generated by Titanium Backup, Easy Backup & Restore and similar applications must be taken from the smartphone memory and copied to the PC, otherwise they are deleted after the Android reset. When backing up to a microSD card, the data should remain in place even after formatting the smartphone. However, as a precaution, I recommend that you still copy the files to your computer. If you need a hand to connect Samsung mobile to PC read my guide on the subject.
To carry out the online data backup you can rely on the services offered for free by Google. If you have connected a Gmail account to your S3 they should already be active, however it is always better to check.
Go to the menu Settings> Accounts> Google of your smartphone, select your Gmail address and make sure that the synchronization functions for contacts, calendars, etc. are set to ON. Then open the application Google photo (if you don’t have it you can download it for free from the Play Store), press the hamburger icon, select the item Backup and synchronization and make sure that the toggle located at the top right is set to ON. The setting Upload size must be configured on High quality otherwise you will not be able to take advantage of the unlimited online space available for photos and videos on Google Drive. If you need more information on how to save Android phonebook or how to upload images online with Google Photos, consult my tutorials on the subject.
Do you use WhatsApp or other messaging services? Don’t forget to make a backup copy of the messages in them as well. If you need a hand to save WhatsApp messages, read my tutorial dedicated to this topic.
Format Samsung Galaxy S3
Now that you’ve secured all your data, let’s take action and see in detail how to format S3. There are two ways to do this: the standard one simply called factory reset and a more advanced one which involves hard reset of the terminal. In both cases, the microSD data is not deleted, but for safety I recommend that you remove the card from the phone.
Factory data reset
To carry out the factory reset of the S3, go to the settings of Android by pressing the icon ofgear found in the menu with all the apps installed on your phone or at the top of the notifications menu. Then select the item Backup and restore, go up Factory data reset and start the Android reset by pressing on first Reset device and then on Delete everything.
After the phone restarts you will have to go through the initial Android setup procedure, then you will have to set the system language, you will have to choose a Wi-Fi connection to connect to, you will have to set up your Samsung and Google accounts etc.
Note: if you also want to format your microSD, go to the menu Settings> Storage> Format SD Card of Android and “tap” on the button Format SD card.
If Android no longer works properly and you are unable to perform a standard factory reset, you can format the S3 using thehard reset. The hard reset is a procedure by which you force the phone to turn off to access the Recovery (a software that works outside the main operating system) and restore Android to the factory state.
To enter the Recovery of your mobile phone you have to turn off the device completely (an operation that you can also perform by temporarily removing the battery from it), then you have to hold down the keys Volume +, Power And Home until the Android logo appears on the screen.
Next, use the key Volume – to move to the item wipe data / factory reset in the Recovery menu, press the key Power to select the option and, in the screen that opens, select the option wipe data / factory reset (always using the Volume – and Power keys).
Finally, select the option yes – – delete all user data, restart the S3 by selecting the item reboot system now and follow the Android initial setup procedure.
If any of the steps in the procedure are not clear to you, try a connect to YouTube, there are many video tutorials (both in Italian and in other languages) that show in detail how to hard reset the S3.
