Android Security
Google has released the March 2019 Android Security Bulletin, giving carriers and device makers a fresh set of patches to install. Though Google puts out the Android security patches each month, the job of actually getting the fixes to end users falls on the telcos and/or device manufacturers themselves. Those partners vary in their ability to release the patches in a timely fashion.
