Thank you.<p>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.<p>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.<p>I think this was the issue: <a href="http:&#x2F;&#x2F;forums.androidcentral.com&#x2F;telus-samsung-galaxy-s4&#x2F;380081-samsung-galaxy-s4-won-t-turn.html" rel="nofollow">http:&#x2F;&#x2F;forums.androidcentral.com&#x2F;telus-samsung-galaxy-s4&#x2F;380...</a><p>So basically I think any manufacturer can fall prey to this - a faulty component that takes months to manifest itself.
