Is it safe to sell your smartphone?
I bought a new phone and planning to sell my old one. I’m afraid my data could be accessed even after I delete it. What should I do. ?
Data is stored in a form of pattern. When you delete files, they are not really deleted at all. The pattern they had created before deletion still exists. unless they are overwritten by other data.
So, if you think that by formatting your device no one will be able to access your data, then you’re wrong.
Personally I use file shredding apps like ishredder and shredit. They delete the data completely and also wipe out free space that might still be containing your deleted data.
but I think still it’s not 100 percent safe. Because technology is advancing at alarming rate. Few years back you could only recover small images but at present you can recover almost any size of data.
so if your device has some really sensitive data (like private images etc) I would personally recommend to not sell your device. This is just my personal thought.
