Factory reset button is an icon already present in your android mobile phones. This icon is actually used to remove all your data and settings from your mobile and bring it back to the previous factory setting. There are many reasons you perform this factory reset setting like for fixing bugs, you reset your mobile when its speed is low, your erase everything from it when you are about to sale your mobile phone.
There is a bad news regarding this factory setting that this factory reset icon can never always delete all your data and this data of yours can be restored with different techniques. This fact has been uncovered by Cambridge university researchers who are studying different aspects of android technology.
Why actually factory reset button is not working
Now there is another question in our heads that why actually this factory reset button in this much latest technology of android doesn’t work, the researchers took a group of android mobile whose technology ranged from android 2.2 to marshmallow 6.0 then they entered some of the Facebook and whats app passwords in them and after that applied that factory reset settings, for a while all the data in the mobile was gone, then with using some technology they found the master token.
A master token can be considered as a key through which you are able to enter into the private and erased data of anyone. The master token allows you to have access to a person’s private things again.
Who to blame
We can blame no one specific in this case; partial blames can be done on different parties. First of all comes the manufacturers, they are blamed for not developing efficient enough software’s to help erasing the data in the flash storage easily as it is the most difficult task to erase the data from the flash storage.
Second is the Google for not giving safe enough options to its users so they can erase the data without any fear. Another sad thing is that even the mobile encryption keys are not now even safe. Once you have encrypted all your data and think you are on the safe side, the hackers takes the turn, they can hack your mobile within minutes encrypt all your data and again have access to your private things.
What can be done now?
The first thing that can users can do is to encrypt their phone using a strong password as a strong password will act like a wall for the hackers and prevent your data from being hacked. A strong password consists of capital letters, small letters, digits and symbols. After using a strong password encrypt your data.
Another solution is to make such an app on Google that fills your flash storage with useless things so that the master tokens gets lost somewhere in all the garbage and became difficult to find, this is the most suitable solution being thought of till now.
