Are you thinking of selling your mobile phone? Then these are
the things you need to know. As, you may believe that you have deleted your
data but that is not so. This could be shocking information for some soul, as
even after you delete the data one can recover them with the help of software
programs designed specifically for that purpose. So, keep calm and keep
reading.
The process of wiping and deleting your data actually
doesn’t remove that data from your phone. What the operating system does is
that it doesn’t delete it, but only marks the spot where the data is situated
as the spot ready to be overwritten with another data
This process is same in each and
computer and mobile devices out there. So, that means the memory devices are
never empty even though you delete everything. It applies to every memory
devices out there, like-the memory cards, memory on your phone and even the
hard disk drives in your computer. So, to tackle this problem there is a
workaround.
What you can do is delete the data first
and fill all of your memory space with useless data or you can encrypt
you memory and delete it again. What this will do is scramble all your data
into useless bits. When you try to look at the data using sophisticated
program, it will show unreadable and gibberish data.
So, if you
have Android devices then you can follow the steps below and if you are an
apple device owner then you need not worry, because encryption is enabled as
default factory settings.
§
First of all, back up your data. There are many
apps out there which can do the job properly.
§
You could copy useless data into your phone so
it will replace your valuable data. But then, it is always better to take the
safe route, follow the next step.
§
Encrypting your phone. To do that, you go to the
settings panel, then to the security panel. There, is this encrypt device tab,
it will ask you to input a six character password with at least one number, if
you haven’t set the lockcode already.
§
After you set your password, go back to the
encrypt device tab in the settings menu and start encrypting your device. It will
take a little more than an hour to encrypt your device, so it is advisable to
connect the charger during the process.
§
After your device is encrypted, it is a walk in
the park. You wipe out the data and then revert back to factory settings.
§
Now your mobile is good as new.
