French blogger Korben discovered the vulnerability, which you can see an example of in the video at the bottom. The exploit involves simply texting the seemingly harmless “=” symbol (without quotes) to a handset, which then causes the smartphone to turn off and reboot.
One supposed solution to this problem is to just install an alternative message app and stop using the one that comes preinstalled with the smartphone. However, Korben has found that the problem can still persist even when switching over to another ROM. This suggests that the bug is actually coming about from a combination of software and hardware issues, or something inbetween, that is only affecting a small selection of MediaTek based manufacturers.
