I have an old iPhone that i'm going to sell it , in addition, my mobile phone also has some messages to deal with , because those are about my bank account, so I tried the factory reset program , and I always thought it was enough to clean them up.
But recently, I've been reading an article on Google.It says that data can't be cleaned up at all after factory reset .
Why ? Is it wrong?
