I just bought a new Galaxy S5 a few days ago as my secondary phone; it has been great experience, I am no stranger to samsung's ecosystem. I found that when I adjust some setting unrelated to a small issue I am facing "Unfortunately IPSec has stopped" message appears. Searched on the internet for a while for anything related it, the results show as an item related to VPN. I do not have a VPN service of a sort, and while diving deeper into the installed applications shows the application IPSec as 0.00kb; not sure if it is a problem or if I should be concerned, the message appears once in a blue moon, and it is not hindering the performance or usage of the phone. Was wondering if anyone faced this issue, is it worth bothering to fix?
