About the crash message, black screen message, ~ Yesterday, my classmate sent me a message that it would crash if I opened it. I don't believe it yet, but it crashed as soon as I opened it.

This is related to the mobile phone operating system, and most of these black-screen short messages occur on "cottage phones". The so-called "shanzhai mobile phone" is a mobile phone produced by a manufacturer without a regular mobile phone license or a network access license, which is also commonly known as a black mobile phone.

Most shanzhai operating systems use MTK platform. This MTK platform, because of its low price, allows many domestic MP3 music player manufacturers to produce mobile phones overnight.

"The message format of blank screen is: (blank line) Note (blank line) Your mobile phone will be blank for one hour (blank line) Do you believe it or not ... (blank line to the end). In these blank lines, there is a musical cue. It is this music tip that makes the phone black. "

This music tip is a component that can test pirated and genuine-just like Microsoft XP operating system on a computer, if it is not genuine software, the screen will be black.
