Just like Samsung and Google, LG also plans to roll out security updates once a month directly to smartphones, in order to help prevent exploits like Stagefright from occurring again. LG confirmed said plans with Wired in an email:
"LG will be providing security updates on a monthly basis which carriers will then be able to make available to customers immediately. We believe these important steps will demonstrate to LG customers that security is our highest priority."
Manufacturers are looking at ways to deploy a process by which updates can be rolled out promptly to consumers without delay. Only time will tell just how reliable said processes will prove for consumers who may be at risk.
