There are times when Your phone starts to stutter, freezes, constantly asks for space, or you want to sell it without leaving a trace.In all these cases, restoring it to its original state might be the quickest way to get it working properly again. The problem arises when you think, "Okay, but I don't want to lose photos, chats, or anything important." Let's talk about how. Restore Android from factory settings without losing your data.
The good news is that Yes, it is possible to factory reset an Android (or even an iPhone) without losing everything.Provided you prepare properly beforehand: backups, knowing exactly what gets deleted and what gets kept, and choosing the right type of reset. Let's look at it step by step, calmly and in plain English.
What does it mean to restore a mobile phone to "factory"?
When we talk about "formatting" or "factory resetting" a mobile phone, we are referring to return the software to the starting point it was in when you took it out of the boxThe operating system is restored to its original state, and almost all traces of use that you have accumulated over time are removed.
In practice, performing a factory reset on Android or iPhone erases Custom settings, added accounts, installed apps, photos, videos, documents, and messages stored in internal memoryOnly the system and applications that came pre-installed are retained (and any system updates you have installed, which do not disappear).
This makes it a very useful tool for Fix software errors, clean up app remnants, improve performance, or prepare your phone for sale, gifting, or service.In return, it involves a very deep deletion of local data, so the previous backup is mandatory if you don't want any unpleasant surprises.
Something that raises many questions is What happens to paid apps and purchases?Even if you delete everything, the apps you've purchased remain linked to your Google account or Apple ID, so you can download them again from Google Play or the App Store without paying again. However, you might lose their internal data (settings, saved games, etc.) if you don't back them up, unless the app itself syncs with the cloud.
What gets erased and what doesn't when you reset a mobile phone
Before touching anything, it's important to be clear which elements disappear and which are saved after a restorationThat way you'll know what you absolutely must back up.
When restoring a mobile phone to factory settings are deleted from internal memory:
- Photos, videos and files saved in internal storage (DCIM folder, downloads, documents, etc.).
- Installed applications for you and all your local data, except for what you have in the cloud.
- SMS messages and call log, if you don't have them synchronized.
- Accounts added (Google, email, networks, etc.) and their settings on the device.
- System settings and customization: backgrounds, ringtones, fingerprints, face unlock, network settings, notifications, etc.
Instead, are maintained or can be recovered No problem if you've done things right:
- Cloud content: everything that is in Google Drive, Google Photos, iCloud, OneDrive, Dropbox and similar services is not deleted from the server.
- Data on SD cardFactory formatting only affects internal memory, not the external card (unless you delete it on purpose).
- System backups (Google One on Android, iCloud or computer backup on iPhone) which you can then restore.
- OS updates that you have installed; the phone does not revert to the old factory version.
- Apps and paid purchases associated with your account, which can be reinstalled at no additional cost.
In some cases you can also "save" data by moving it beforehand: transferring photos and documents to a microSD card or a PCby exporting contacts to a vCard file, or by using exports from apps that do not sync automatically (for example, some calendars or offline note managers).
Why and when is it worth restoring your mobile phone?
There are several situations where a factory reset is a good idea and not just a "last desperate resort". When your mobile phone is very slow, freezes often, or always crashes in the same appsThere are likely corrupted configurations, remnants of uninstallations, or temporary files that are not properly cleaned.
Over the years, the system accumulates cache, leftover data, old settings, and apps you no longer useA complete factory reset wipes all that data at once, restoring considerable speed even to older phones. It doesn't work miracles on the hardware, but it often makes all the difference.
Another common reason for restoring is leave the device ready to be sold, given away, or returned to the companyThis ensures that no private photos, sensitive documents, or open accounts remain. However, on iPhones and also on Android devices with certain security layers, it's essential to remove account protections beforehand (Find My iPhone, Google FRP, etc.).
It can also be a security measure when You suspect your mobile phone has a virus or some kind of complicated malwareA factory reset removes malicious apps and their files, provided the problem isn't a more serious system modification. It's the cleanest way to reset a compromised device.
Finally, many people choose to restore right before or after a major system updateWhen the phone carries over bugs from previous versions, starting the new version from scratch reduces configuration conflicts that sometimes appear after several years of use.
What to do before formatting: backups and locks
If you want to restore your mobile phone to factory settings without losing everything, The most important step is not in the reset menu, but in the previous backup.Without a backup, anything deleted is gone forever.
Before you touch anything Review these key points:
- Photos and videosUpload them to Google Photos, iCloud, or another cloud service, or transfer them to your computer or an SD card.
- Contacts and calendars: sync them with your Google or iCloud account; otherwise, export a vCard file to save it separately.
- SMS messages and call logOn Android you can use the Google backup or specific apps; on iPhone they are included in iCloud or the encrypted computer backup.
- WhatsApp and similar chats: Activate the backup to Google Drive (Android) or iCloud (iPhone) and make sure it is completed just before the reset.
- App dataMany sync automatically (Gmail, social networks, cloud notes…), but others require manually exporting or saving files.
In addition to the data, consider the security and blocking aspects: Disable Find My iPhone on iOS and remove the primary Google account on Android. If you are going to sell or give away the mobile phone, to prevent the next user from encountering an activation lock that is impossible to bypass.
Finally, check two basic details that many people forget: battery level and connectionMake sure your phone has at least 50-60% battery charge, or better yet, plugged in. If the restoration process involves downloading backups from the cloud, use a stable WiFi network.
How to make a backup on Android
Android makes it quite easy to save the most important information using Google One backup and associated services like Google PhotosEven so, it's a good idea to check that everything is active and force a recent backup before restoring.
For a general device backup on Android, follow this approximate route (may vary slightly depending on brand and version):
- Sign in Settings and look for the section Google or simply “Backup”.
- Tap on Backup o Google One Backup.
- Turn on the copy switch if it isn't already on and check. what data does it cover (compatible apps, call history, SMS, settings, WiFi, etc.).
- Press on Create backup now to upload a recent version.
For photos and videos, it's ideal to combine it with Google Photos:
- Open the Google Photos app and tap your profile picture.
- Sign in Photo Settings > Backup.
- Activate the copy and choose your preferred upload quality.
Regarding WhatsApp, which is usually the most sensitive, the app has its own backup system on Google Drive: Settings> Chats> Backup, selecting the Google account and forcing a manual “Save” just before the reset.
How to back up your iPhone
In the Apple ecosystem you have two main paths: iCloud (in the cloud) or an encrypted local copy on a computer with iTunes/FinderIdeally, if you can, you should combine them.
For copy to iCloud:
- Go to Settings and click on your name at the top.
- Sign in iCloud > iCloud Backup.
- Activate this option and click on Back up now.
This copy includes settings, apps, photos if you use iCloud Photos, Health data, passwords, and moreProvided you have enough space. If the free 5GB isn't enough, you can upgrade your storage plan for a small monthly fee.
If you prefer (or are forced by space limitations) to make a copy on your computer:
- On Mac with macOS Catalina or laterConnect your iPhone, open it from Finder, go to the "General" tab, and select Back up all iPhone data to this MacIf you digitize it, passwords and sensitive data are also stored.
- On PC or Mac with macOS Mojave or earlierConnect your iPhone, open iTunestap the device icon and then tap on backup now.
Anyways, Wait until the copy finishes completely. Before you start deleting anything. This way you'll ensure you have messages, apps, photos, and other content that you can later recover when you reset your iPhone.
Soft reset: Fix errors without erasing your data
You don't always need to perform a complete factory reset to get your phone working properly again. Often, you can opt for what's commonly called... “soft reset” or partial reset, which corrects errors while preserving photos, apps, and files.
On Android, a very useful option is clear the cache partition from recovery modeThis process deletes temporary system files without affecting user data:
- Turn off the phone completely.
- Turn it on by holding down the buttons Power + Volume up (on some models it's Power + Volume Down) until the recovery menu appears.
- Move with the volume buttons and select Wipe cache partition with the power button.
- When you're finished, choose Reboot system now.
You can also reset only some settings from the menus themselves: many Android devices have options like this. Reset network settings o Reset system settings within “System > Recovery Options”, which restore WiFi, Bluetooth, default apps, notifications and permissions to their original values without deleting your photos or apps.
Something similar exists on iPhone: Settings > General > Transfer or Reset iPhone > Resetwhere you can choose to reset only settings, or only network, without deleting content. This is especially useful if you're having connection problems, Bluetooth that won't pair properly, or notifications that aren't arriving.
These methods are ideal when the phone It's simply slower than normal or it has occasional errorsThey do not replace a complete format in case of serious failures, but they help to extend the life of the device without having to completely wipe it.
How to factory reset an Android phone (main methods)
If you already have all the backups made and want to do a full format, Android offers several ways to do it: From the settings, from recovery mode if it doesn't boot, from a PC with tools like Fastboot, or even remotely with Find My Device.
Restore from system settings
This is the simplest method and the one you'll use if the phone turns on properly. The general path (which may vary slightly depending on the brand) would be:

Restore from recovery mode if the phone does not start
When your phone gets stuck in a loop, stuck on the logo, or won't let you access the system, you can use the recovery menu. It's a slightly more "technical" environment, but following the steps is straightforward:
- Turn off the device completely.
- Turn it on by pressing both buttons at the same time. Power + Volume up o Power + Volume Down (depending on the brand: Pixel, Motorola, Xiaomi, etc.). Some Samsung phones with an extra physical button (Bixby) also have that button integrated into the design.
- When you see the recovery menu, navigate with Volume + / – and select with On.
- First, if you want, you can use Wipe cache partition to clear cache; then, for a full format, choose Wipe data/factory reset.
- Confirm on the next screen (Yes, Factory data reset, etc.).
- When finished, select Reboot system now.
This process erases all contents of internal memorySo you should only use it when you already have backups or there's no way to make them because the system is unresponsive.
Format Android from PC using Fastboot
It's a more advanced method, used primarily by technical services or users who tinker with ROMs. It allows send deletion commands from computer to mobile using the ADB/Fastboot tool.
In general, the The procedure would be:
- Install the following on your PC: drivers of your mobile and the ADB and Fastboot tools.
- Boot the device into mode fastboot or bootloader (usually Power + Volume Down with the phone turned off).

- On the PC console, run fastboot devices to check that the terminal appears.
- Launch the command fastboot erase userdata to delete all user data.
- When finished, run fastboot reboot to restart the mobile.

When is it advisable to go to a technical service center?
A factory reset usually solve most software problemsHowever, if the problems persist after formatting the phone, it is very likely that the cause is hardware-related and not configuration-related.
It is advisable to consult a technician Yes, after restoring:
- The battery continues to drop rapidly. even without using your mobile phone much.
- The screen is malfunctioning.: ghost touches, dead zones, spots or flickering.
- Phone overheats or it doesn't charge properly despite trying other chargers.
