How to Secure Android Smartphone
Most of us thing, “Android Factory Reset” remove everything. Then I Should Tell You. Oh! Brother. You are completely wrong!!!!
Because recently some researcher discovered “Android Factory Reset” does not actually remove all data. I personally research lot’s about this. Finally I figured it out it’s true indeed, Factory reset actually can not remove all of your personal data which was not encrypted. Few weeks ago, I brought a second hand Samsung Galaxy J7 from Bikroy.Com, after bringing the phone at first I did the Factory reset, but after hearing the news “some researcher discovered “Android Factory Reset” does not actually remove all data” I tried one h*cking which I have found on onionWEB, I was just shocked!!!
All of his contact number I can see.
So why that is happed?
Is this their bug?
Or is this some miscalculation?
Or I didn’t actually done the hard rest?
Answer is simple, previous user of Samsung Galaxy J7 never encrypted his mobile data. It’s not Android OS fault neither mine.
Contact number are really some private data of a individual. Besides contact number, there must be some leakage about Phone Data file. I am not a professional hacker so i didn’t know how to hack android complete to gain it’s data. All I understand that “android hard rest/Factory reset doesn’t remove all of our personal data” somewhere in memory chio those still remain.
