HOW TO PERMANENTLY DELETE DATA FROM AN ANDROID DEVICE
Smartphones have almost become
everyone's digital extensions.20 years ago there weren’t any
smartphones and since then a lot
of things have changed. Now we can’t even remember the last time we actually
didn’t use our smartphone for a whole day. Mobile smart devices and mobile
internet are changing the way we do things and how we connect with other people They
are one gadget that people have with them almost the entire time. That said,
smartphones are not only used for communication, but also hold a whole bunch of
personal user information like contacts, photos, email and more. So if one
plans on selling off their smartphone or
giving it away to someone else, it is important to ensure that all the data on it is
securely erased and the device is digitally wiped clean.
Factory Reset:
Factory Reset, also
called hard reset will restore your
Android device to the state where it was
made out in the factory. That is, all installed applications, software,
passwords, accounts and other personal data you have stored on the internal
phone memory, will be erased or wiped out clean. What still stay are the
settings by the producers and files downloaded to the SD card. But the apps
need to be reinstalled or restored from the backup file. No matter for which
reason you need to perform a factory reset on your device, it is effective and
quick to bring your Android back to work again.
Note: We would like to suggest you to backup your Android Data before
factory reset.
It's a common misconception that
doing a 'Factory Reset' is the ultimate way of securely deleting data from a
smartphone. But that's not the case, as a file is not actually erased when it's
deleted. Only the information it contains is marked as deleted/hidden into some
other free location on the storage.
Factory reset reverts a device to
its default state. And although majority of data gets deleted this way, small
bits of information like multimedia, email etc. might remain in the internal
memory.No worries, as it's easy to 'permanently' erase anything and everything
from and Android device.
For those who are considering disposing off their old smartphones, this can
come in really handy. Here are two ways of securely erasing data from an
Android device.
Encrypt device storage:
Encryption converts
data and information stored on a smartphone into a cryptic format before
factory reset is initiated. Without proper decryption, the data just appears to
be a garbled mess that makes no sense. Encrypting device storage
ensures that even if some files are somehow left after a factory reset
operation, they just appear as random rubbish and not the actual deal.
To encrypt device's storage,
navigate to Settings > Security (or related setting) and tap on the 'Encrypt phone'
option. Based on how much data is stored on the device, this may take a while.
Once the encryption is done, factory reset can be performed.
Overwrite with throwaway data:
Although encrypting the device and then doing a factory reset is generally
enough to erase all the data securely, doing a bit extra doesn't hurt. To do
this, set up the smartphone after factory resetting it. Only this time, make
sure no email details are added.
Once the setup is complete, record a junk video for as long as the internal storage on the device doesn't get filled up. Doing this will overwrite the free space with throwaway data.
