Occasionally discovered drops, theory is feasible, did not practice.
We have a long-distance dialing 17951 to have preferential tariffs, so you have to add it. The number of "home" in even mobile phone is 0832 *******. If you have more, you will find that dial 179510832 ********************************************** So first thought that the phone can identify a special number.
Later, I received a call from a day, and the person who called the phone was Lake2, halo, see the ghost, how to call himself (I don't know how to record my number in the phone)! Later, I took its number. I originally a difference with me (he 135 *******, I am 138 *******, * is the same). As a result, this problem was discovered.
When the phone receives (dialed), the same storage is matched, the problem is here, he only matches the post-8 bit, and the last 8 is the same as this record. That is, as long as you can buy the same number, you can deceive the target's friends (of course, he has to exist the number of the person, and the target mobile phone has this problem. I borrow Other brand phones have also tried, and there is this problem. You can also test, give me the result).
It's so much, huh, huh.
