[Tech] – How to Permanently Delete Your Private Files When You Sell your Android

Has this ever happened to you? that the
smartphone which you are about to sell
might reveal all the important and
personal information to someone else?
Yes, it’s possible because we all always
have the urge of trying every other new
smartphone which has been launched in
the market. Now you may end up buying
that smartphone or you will sell your
last smartphone, add few more bucks to
it and then buy the new one.

Can you get Rid of your Data by
Deleting it?

Obviously you must have taken care of
that problem by restoring your device
which in turn would have removed all
that data available over the internal
memory of your smartphone there are
many applications out there which can
be used to recover the deleted files from
the internal memory of a smartphone.
So, what is the remedy to this problem,
how can you take care of this?

Try not to sell you external MicroSD
card along with the smartphone because
internal memory can be taken care of to
some extent but MicroSD card can be
taken out of the smartphone and more
adverse Windows Based applications
can be used to recover the data from
external memory.

Why Your Data Get’s recovered even
after you Delete it?

When ever you delete a file, space is
freed up as far as operating system is
concerned, but the data remains in the
Nand Flash storage. Nothing much
changes to your Nand Flash storage or
for eMMC controller. Your OS just over-
writes the Nand Flash cells once you
load more data. Thus if you restore your
device, load it completely with
unimportant media files and re-restore
it, you can easily get rid of your files
permanently. That sounds like too much
hardwork? You can also follow the
following approach.

How to Permanently Delete Your Data
by Encrypting It

In your smartphone, there is an option
named ‘Encrypt’ available under the
Security option. You should use that
option to encrypt all the data and then
restore your device. So, that even if a
software manages to retrieve from your
internal memory, it will be completely
encrypted and thus he will have to
decrypt it to look for into it (which is
really tough and not doable to a huge
extent).

Under Settings, there is an option named
‘Security’.

You can see an option named ‘Encrypt
Phone’. Tap it.

You will see this screen. Follow these
instructions and keep your phone
connected with a charger.

After tapping, this you will be taken to
the final screen after which the
encryption process will start. Please be
aware of the risks before doing it.

It will be great if you could restore it
and then load it with some bogus data
like lots of music and movies, just to fill
the phone memory. Remember that we
are asking you to encrypt the data when
you are planning to sell it and not when
you are planning to keep using your
smartphone, because once you encrypt
your data, you may have to de-crypt it
again and again.

Conclusion

There are many applications available
on the Google Play Store to encrypt the
data but it will be advisable you use the
default feature available in your
Android Settings section. This is the best
way you can take care of all the
personal data available on the device
and feel free to sell it.
