This posts has all the possible "secret" codes that the HTC One X has, I didn't looked if it was a Samsung only or not. I tested the ones that could be more dangerous by remote dialing and none of them work. You can't say that from Samsung's so we are protected and are good news. HTC even said to the Verge that they don't have any factory reset USSD code so there's no way our devices will be harmed with this.
Vulnerable is just a way to say it. Are we vulnerable from remote e-mail sendings? Any page can do any harm to our phones, only pop up some configuration page, but there ends, so saying that it is "vulnerable" adds a negative sense that doesn't makes Sense on HTC One.
So, this is to remove the hysteria about "all Android devices can be deleted from the Internet".
