Apparently another security issue was found with the Note II, S3 and Meizu MX. But in simple terms, what does this mean? You can get an easy root but it will leave your phone vulnerable to attacks.
This also effects devices using the Exynos 4210 or 4412 processor, which are primarily Samsung devices.
Quote from Android Headlines:
"But luckily the developer community is quick with things like this and have already found a fix. Thanks to XDA user RyanZA, there is already a patch to modify these permissions on all the affected devices. But the only downside is that users have confirmed that this fix cripples the camera on all these devices. So far Samsung has not made a comment on this security flaw on most of their flagship devices, but we expect to hear something soon from them.
