Samsung detailed the January 2018 security patch a couple of weeks ago and it's now gradually rolling it out to compatible devices. As expected, the company's mid-range and low-end devices are receiving it first, we've yet to see the patch being rolled out for a flagship handset. Samsung has rolled out the January 2018 security patch for the Galaxy J3 (2017) and the Galaxy J1 mini in a handful of markets today.
January 2018 security patch
The January 2018 security patch brings fixes for five critical vulnerabilities that were discovered in the Android operating system aside from fixes for several low, moderate and high-risk vulnerabilities. Samsung fixed 13 Vulnerabilities and Exposures (SVE) in its own software and has included the patches in this security maintenance release.
Samsung is now rolling out firmware version J330FXXU3ARA3 for the Galaxy J3 (2017) in Russia and Slovakia. It's only a matter of time before the update makes its way to other markets. The firmware files are available for download from our firmware section.
It's also rolling out firmware version J105FXXU0ARA2 for the Galaxy J1 mini in Iran, Kenya, United Arab Emirates, Saudi Arabia and South Africa. All relevant files are available from our firmware section. Samsung has already released said update for the Galaxy J1 mini Prime.
