For the phone: is it an iPhone or an Android one? If Android, what version?
My teenage son was given a smartphone from us, but spends all his time watching pornography. I want him to be able to have his phone and to use internet...but this had become a major problem for him. I've tried taking his phone and iPad after he's promised to stop watching it but this doesn't seem fair and the internet is necessary for many things in his life rn. I don't believe he has stopped and has been fine since then with no urges, or sneakish behavior. Is there a way to block internet conveniently or permanently... Or is there a program where I can see Every site visited, even if in private mode. I know there are many ways to 'hide' browsing or find alternative modes of private... But I only know it can be done, and he Actually knows How To do these things. Please Help. Hate that I've been keeping him from this, but Need to make sure that doesn't happen again!
