Since don't like much these Apple products I let my son play this device most of the time. One day he came to me and I keyed in my password to download a free game app but I don't have an idea that it will remains active for 15 mins.
After 5-10 mins luckily in my surprised the credit card company called me about $99.99 iTunes purchased. I don't have an idea he switch to play smurfs and told them to discredit the transaction.
Since I own this device I never purchase any app I only downloaded free games and app.
I don't know if this only happened to me in this forum but after googling it this is a common problem and that is why they are top earner on apple store, even many people calling this a scam. Why they did not ask again for password if you would do purchases I think they are targeting kids that would just tap n tap what ever that pops come out. Why in default the IAP is enable?
Lesson learned and more reasons to hate Apple...Just sharing my experienced.
