Do not upgrade to lollipop if you want to retain IR blaster capability that was previously available in Kitkat.
I have worked closely with Color Tiger, producers of "Smart Remote" that worked flawlessly with Kitkat. I was so impressed with their product that I became a beta tester. I recently upgraded to lollipop and have now lost IR blaster capability. None of my electronics respond anymore. I reinstalled the application and am now getting error messages stating that there is no IR blaster capability. ColorTiger has informed me that they have 14 other users with identical tablets to myself and they suddenly lost IR capability. I also installed a free version of another IR remote and it to couldn't find IR blaster capability either.
I called Samsung and they are washing their hands of the problem redirecting me to Google instead. However, they are unable to give me a contact number or email in which I can contact. Does anyone have a contact link to Google's Android to report issues like this.
