I contacted Samsung Technical support in July 2016 regarding having issues with my new Galaxy S7 Edge phone, screen freezes, Volume very low could not here the other person call, battery issues. They confirmed by letter that phone has been tried and tested by Samsung Authorised Repair agent. I can confirm none of above issues were sorted out, still have issues. I contacted Samsung head office, that were not vey helpful at all, they requested I contact Technical support for the phone to be collected and repaired again. I requested on numerous times for my S7 edge to be replaced, they refuse to do so. This complaint is still on-going as of 1st September 2016. I would never recommend Samsung to Anyone.
