Returning the smartphone to its original state is a radical, but often necessary measure to restore the device’s functionality. Users resort to this procedure when the gadget starts to slow down, strange errors appear, or it is necessary to transfer the phone to a new owner. However, before pressing the treasured button, a natural fear arises: what exactly will disappear from my device?
The process, officially called Factory Reset or factory reset, deletes all user information accumulated during operation. This is not just clearing the cache or deleting shortcuts, but completely formatting the data partition. It is important to clearly understand the difference between deleting files and deleting accounts so as not to lose access to important services.
In this article we will analyze in detail the fate of your photos, contacts, applications and system files. We will look at the nuances of working with a memory card, the impact of Google blocking (FRP) and prepare a step-by-step action plan for a safe procedure. Don't rely on luck - proper preparation will save your memories.
Complete deletion of user data and media files
The most obvious and painful result of a reset is the loss of all files created or downloaded by the user. The internal memory of the smartphone will be completely cleared. This applies to photos taken with the camera, videos, voice notes and screenshots. If you stored documents, music or books in the internal memory, they will be destroyed without the possibility of recovery using standard means.
Particular attention should be paid to folders that are often ignored during manual deletion, but are erased during a full reset. These include downloads from instant messengers, browser caches with saved passwords (if they are not synchronized) and offline maps of navigation applications. Android does not differentiate between important documents and temporary files in this mode - all contents of the user section are deleted.
⚠️ Attention: The “Trash” function in the gallery of many smartphones is also cleared when resetting settings. Files that you previously deleted and placed in the trash will disappear completely, and it will be impossible to restore them even through special utilities.
Before resetting, be sure to check the “Download” folder and messenger folders (WhatsApp, Telegram), since this is where important files are often stored, which are forgotten during backup.
Process formatting affects not only visible files, but also hidden system logs and application settings. Once turned on, the phone will look like you just took it out of the box in the store. No traces of your previous activity will remain in the internal memory.
The fate of installed applications and their data
All third-party applications that you downloaded from Google Play Market or installed through APK fileswill be permanently deleted. This applies to social networks and games, as well as banking clients and work tools. Only those apps that were originally built into the firmware by the manufacturer will remain.
It is important to distinguish between deleting the application itself and deleting its data. When you reset the settings, absolutely everything disappears: logins, progress in games (if it is not saved in the cloud), interface settings and app databases. For example, if you used an offline translator with downloaded language packs, after resetting you will have to download them again.
- 📱 All shortcuts and widgets located on desktops are deleted.
- 🎮 Progress in games is reset if synchronization with Google Play Games or a developer account has not been enabled.
- 🔐 Saved passwords in browsers and password managers stored locally on the device are erased.
- 🗺️ Navigation maps (for example, Yandex.Maps or Google Maps) lose loaded offline regions.
Some applications may behave differently after re-installation. For example, banking apps will require re-binding the device and entering code words, as the unique identifiers of the phone will be reset in the eyes of the security server. This is a normal practice for protecting your finances.
Contacts, messages and call history
One of the most critical moments is the fate of the phone book and correspondence. It all depends on where exactly you saved your contacts. If the numbers were stored in the phone memory or on the SIM card (in the case of older models or specific settings), they may be lost or require separate export.
Modern smartphones running Android by default offer synchronization of contacts with your account Google. If this function was active, then after entering the login and password on the reset device, all numbers will automatically return to their places. However, the history of SMS messages and the call log are almost never automatically synchronized in full.
| Data type | Deleted upon reset | Recovery possible | Storage conditions |
|---|---|---|---|
| Contacts (Google) | No (in the cloud) | Automatic | Synchronization enabled |
| Contacts (Phone) | Yes | Only from backup | Manual VCF export |
| SMS / MMS | Yes | Difficult | Special. backup applications |
| Call log | Yes | No | Not saved by the cloud |
| Whatsapp messages | Yes (locally) | From Google Drive | Set up backup |
⚠️ Attention: The history of correspondence in instant messengers (WhatsApp, Viber, Telegram) is stored locally. For WhatsApp, you must manually create a backup in the chat settings before resetting, otherwise the correspondence will be lost.
To save your call and SMS history, it is recommended to use specialized backup applications that create a single archive file. This file then needs to be transferred to a computer or to the cloud, since during a reset it will also be deleted if it remains in the internal memory.
System settings and interface personalization
Resetting to factory settings returns not only clean memory, but also the standard appearance of the system. All your personalizations will be canceled. This includes installed wallpapers, themes, fonts, and icon placement. The smartphone will return to the appearance it had when it was first turned on.
System settings will also be completely reset. You will have to re-adjust the screen brightness, backlight timeout, sound and vibration settings. Complex settings such as power saving modes, gesture controls, and accessibility for people with disabilities will be reset to their default settings.
What happens to accessibility settings?
When reset, all accessibility services (TalkBack, screen magnification, subtitles) are disabled. If you relied on them to control your phone, you'll have to reactivate them immediately after running the setup wizard, which can be difficult without first preparing.
All saved Wi-Fi networks and Bluetooth device pairs are also deleted. The phone will “forget” your home router, wireless headphones and smart watches. The first time you connect to the Internet, you will need to re-enter the Wi-Fi password, and for headsets, you will need to carry out the pairing procedure from scratch.
The impact of a reset on the SD memory card
The issue of data security on the memory card is one of the most controversial. By default, when you select “Reset settings” in the menu, the system does not format external SD memory card. Your photos and files on it should remain safe. However, there are important nuances that you need to be aware of.
If the memory card was configured as “internal memory” (Adoptable Storage), the situation changes dramatically. In this mode, the system encrypts the card and combines it with the built-in storage. When you reset the settings, the encryption keys are lost and the card becomes unreadable for other devices. In fact, the data on it becomes inaccessible, although physically they may remain there.
To avoid problems, it is best to remove the memory card from the slot before the procedure. This guarantees 100% data safety and will eliminate accidental formatting if you accidentally click the wrong checkbox in the advanced reset settings.
⚠️ Attention: Menu interfaces may differ on smartphones of different brands (Samsung, Xiaomi, Pixel). Always carefully read the warning text before pressing the confirmation button - there may be an item “Clear SD card”, which may or may not be active by default.
☑️ Preparing the memory card
FRP lock and Google account
One of the most important aspects of modern Android is an anti-theft system known as FRP (Factory Reset Protection). If you reset the settings through the menu of a switched off phone (Recovery mode), and not through the system settings, this protection will work.
After turning on the reset phone, the system will require you to enter the login and password for the Google account that was synchronized with the device before the reset. This is done so that a thief who steals a phone cannot simply erase the data and use it as new. Without knowing the owner's password, the phone will turn into a “brick.”
If you are selling a phone, it is extremely important to delete your Google account before resetting the settings. To do this, you need to go to Settings → Accounts, select your profile and click “Delete account”. Only after this action, a secure reset will not raise questions for the new owner.
Deleting your Google account before resetting is the only way to guarantee avoiding FRP blocking when transferring the device to another person.
Frequently asked questions about resetting settings (FAQ)
Will the Android operating system be deleted during a reset?
No, the operating system is not deleted. The reset only affects the user data section (/data). The Android version, security patches and built-in system applications will remain at the version that was installed before the reset. The system is updated separately.
Is it possible to restore data after a reset without a backup?
In modern versions of Android with encryption enabled, data recovery after a full reset is almost impossible. The encryption keys are deleted along with the data, making the residual information on the memory chip unreadable. The chances of returning photos or documents without a preliminary copy are close to zero.
How long does the reset process take?
Usually the process takes from 5 to 15 minutes, depending on the amount of data and the speed of the smartphone’s built-in memory. The phone may reboot several times during the process. It is strictly forbidden to interrupt it, as this can lead to damage to the file system.
Do you need to remove the SIM card before resetting?
It is not necessary to remove the SIM card; the data on it (contacts, if they are stored there) will not be affected by resetting the phone settings. However, removing the card is recommended to avoid accidentally resetting access point settings (APN), which are sometimes tied to the SIM profile in the system.
