If you are planning to sell your Android phone to someone, you will want to make sure that all your data is wiped clean. Deleting files manually from Android phone is not the right solution. You need to make sure that every bit of data is unrecoverable. Let's have a look at different methods to erase data from your Android phone.
If you just need to remove the everything from your Android phone, you can use this method. However, remember that it does not delete everything completely and it may still be recoverable. In case you are not planning to sell the phone, but you simply need to clear everything so that you can start afresh with your phone, this method must suffice.
You can delete the files one by one on your phone or follow these steps:
1) Connect your Android phone to the computer with a USB cable.
2) Wait for a few seconds for the computer to detect your phone.
3) The internal storage and SD card both will appear as external drives on your computer. For instance, if you have Windows computer, you can go to 'Computer' (or ‘My Computer' for XP and earlier versions.) You will see a phone icon. Double click it to see the storage listed as drives.
4) Now, you can right click on the storage you wish to delete. Choose format, and simply format the drive.
NOTE: Remember that this method may not necessarily work as some of the files may still be in use by your Android phone. someone can use a data recovery program in order to find or locate deleted files even after a factory data reset or deletion. Moreover, it could turn your phone into brick. This is why it is best to use other methods we have outlined below to ensure proper wipe.
Factory reset, supposedly, wipes the device clean and makes it safe to hand over to a stranger (in case you are selling it.) If truth be told, there are gaping loopholes in this method and thus there is more you need to do than just factory reset. We will talk about it later. Let's first take a look at how we can do the factory reset.
Before you factory reset, it would be a great idea to encrypt the data. By doing so, the data on your phone will be scrambled and, in order to unscramble it, a key will be needed. So, this makes your phone and data pretty much unrecoverable even if factory reset doesn't wipe it all.
Again, the steps may vary slightly depending upon the phone model. For instance, certain phones have Backup & Reset option in Additional Settings in the Settings menu.
NOTE: Is A Hard Reset Enough? -- NO
Does performing a hard reset actually guarantee that your information is gone for good? The answer is "NO", it didn't actually delete all of the data from your phone and still remain. There are many professional Android data recovery can easily recover them. Another big problem with this method is that even if you encrypt the data, an expert may be able to break the code and steal your information. If you wish to be completely sure that the data is fully unrecoverable, you can use Android Data Eraser.
See how data recovery progarms scan and recover your data after facotry reset.
Are you surprised to see the scanning result? Once the data was scanned, the data can be recovered to computer with one click.
