How to remotely delete data from an Android phone. How to reset data (hard reset, factory reset) on Samsung Galaxy How to delete all data on an Android phone

There's only one thing worse than losing your phone: a lost device with a lot of personal data on it. If the thought of someone else gaining access to your apps, email, or secret plans for world domination scares you, then we have a solution. Here's how to remotely delete data from Android phones.

Make sure you can delete your data while your phone is still with you

If you want to be able to remotely wipe your phone, there are two settings you need to enable before your phone goes missing. They should be enabled by default, but it's worth checking to be sure.

Go to Google Settings > Security > Android Device Manager. Find Remote Lock and Reset and make sure the feature is enabled.

The second switch that needs to be activated is also located on the Android Device Manager screen: find Remote device search, and make sure that the function is active. If these options are not enabled, Device Manager will not be able to locate the device.


Android Device Manager works on tablets too, but if you have multiple user accounts, only the person registered as the owner of the tablet can configure Android Device Manager settings.

Taking slightly different measures is also a good idea: don't store anything important on the MicroSD card (remote erase can't erase that either), make sure you have a strong code or complex locking pattern, and consider investing in an app, e.g. , AirDroid or Lookout. Both apps offer a remote wipe feature, but they can also transfer sensitive data before deleting it.

How to remotely wipe your phone

Oh no! Your phone is missing! It's time to take action, and by action we mean Android Device Manager. You can access Android Device Manager in two ways: through the Android Device Manager app on another Android device, or through the Android Device Manager website.

Once you are logged in, Android Device Manager will try to find the missing device. If it is possible to receive a signal, you will see the location on the map. You will also see three options: call, block or clear. If your device is disconnected or can't get a signal, Android Device Manager will report its location when it connects to Wi-Fi or a cellular network.

At this point, you can erase everything on your phone, but we highly recommend trying less drastic solutions before deleting everything. Try in this order:

Use Android Device Manager to Make Your Phone Ring

More often than not, people simply forget where they left their phone and lose it; they are stolen less often. To eliminate this option, use Android Device Manager to force your phone to ring at maximum volume for five minutes. This will allow you to find your phone if it falls on the floor of your car or is hidden in one of your children's slippers.


Try this before you go all out - lost phones are often simply found in a different location

Changing the lock screen

There is a second light option for you - changing the screen lock so that when the phone turns on next time, your message will be on it. "GIVE ME MY PHONE BACK" will probably be counterproductive, but a "Please call me" message with a modest reward may work.


Have you tried this? Did not help? OK. It's time to delete your data.

Delete your data

Using the Clear function will completely erase all data from your phone or tablet remotely. This is the same as a factory reset, meaning all your settings, music, photos and apps (except the SD card) will be deleted. As with blocking, if the missing phone is turned off, then when it is connected to the network, this option will remotely erase everything from it.


If you are afraid to use this option, then you should go to your Google account and deny access to your missing phone. We would also recommend changing passwords for online services. The chances of your lost phone falling into the hands of criminals and them gaining access to all your data are slim, but it won't take you long to use this feature.

What should I do if Android Device Manager can't connect?

If Android Device Manager can't connect, there are two more things you can try. Google Maps tracks your phone's movement history, or at least it does if you haven't turned it off in your Google Account, so you can find out where your lost phone was by visiting the Location History page and find out the time. It won't help you find out where your phone is now, but it will tell you where it has been.

Another option is to use an app like Android Lost, which works great on older Android devices. This is one of the few solutions that can be installed remotely, so it's a good option if you haven't enabled the above Android Device Manager features. The app and website look terrible but work well, although the device still needs to be online via a cellular or Wi-Fi connection.

Deleting data from Android

Android smartphones store user information in three places: in their own memory, on removable media (SD cards and SIM cards) and in linked accounts. If the owner usually remembers about removable media, then the rest is very often left without due attention. Resetting to factory settings, which is most often limited to before sale, does not erase everything. Once you dig deeper, your confidential data is no longer just yours.

So, to properly prepare your phone for sale or transfer to a new user, do the following:

  1. Remove SIM and SD cards.
  2. Copy the necessary information from the device’s memory to another medium.
  3. Sign out of all applications and Internet services that you used on your device.
  4. Delete remaining contacts, SMS, mail, web browser history.
  5. Delete all accounts associated with your phone, not just your main Google account.
  6. If you have root rights, remove them.
  7. Clear your memory with complete data destruction tools.
  8. Restore your device to factory settings.

Logging out of accounts

The first and second points, as a rule, do not cause any difficulties for anyone, so let's start right away with the third and fourth.

Take the time to launch every application and web resource on your phone where autologin is configured (automatic login) and press the exit button. Especially in applications that will remain on the device after a factory reset. This measure may seem unnecessary to you, but it is better to spend 10 minutes than to later rely on the decency of the new owner.

Cleaning contacts, SMS and browser history

Launch the application " Contacts", mark everything that is here (after removing the SIM cards, only what is stored on the phone will remain here) and tap the trash can icon.

Do the same with saved SMS and website browsing history in the browser, which will remain on the phone after recovery.


We delete email accounts and correspondence

Launch the application " MailGmail", open the list of mailboxes registered in it and click " Account management».

Tap the first account line, go to the menu hidden behind the three dots and select " Delete" Do the same with the other accounts, leaving one linked to Google Play. You will need it to further clean your phone.


Deleting accounts is convenient because it works on almost any Android smartphone, regardless of modification and firmware version.

Remove Root rights

To remove root rights (if they do not come from the factory, which is found on some strongly Chinese gadgets), they usually use the same application with which they were obtained.

Removing root rights in the Kingroot application.

If you have difficulty finding the option “ Unroot"in your application, use the instructions for it or the universal utility Universal Unroot. The utility will help you check whether the deletion was successful Root Checker. But, unfortunately, the developers of both do not guarantee their successful operation on all devices.

After removing root privileges, reboot your phone.

Clearing the device memory

Before the final step - restoring the phone to its factory state, it is very advisable to erase all personal data from the storage so that it cannot be restored.

Below is an incomplete list of free applications from the Google Plat Market that successfully cope with this task:

The option is called wipe data/factory reset.

After restoring factory settings, the smartphone is ready for sale.

Deleting data from iOS

Releasing iPhone and iPad user data is easier and faster. Of course, their owners also need to remember to remove the SIM card and copy valuable data from the device’s memory to the cloud or other media, but the rest is literally 3 touches of the screen.

So, to reset an iPhone based on iOS 11-12 to the state it was after purchase, do the following:

  • Open settings and go to the " Basic».
  • Tap " Reset" at the bottom of the screen. Enter your Apple ID password if prompted.
