Thank you.

Funny enough I experienced a similar issue with my S4 a few years ago. One day it just died - no messages, no nothing. Completely out of the blue, no falls or anything.

I took it to Samsung repair, they sent it off and returned it to me in a few weeks. I looked on the forums and apparently it was a fairly common (ie thousands of people affected) issue. Same reason - a random hardware chip malfunction that manifests itself after 6-9 months of use.

I think this was the issue: http://forums.androidcentral.com/telus-samsung-galaxy-s4/380...

So basically I think any manufacturer can fall prey to this - a faulty component that takes months to manifest itself.
