I took 1Day to the Disputes Tribunal some years ago over a fault that developed in the charging port of a Galaxy Tablet. I'd had it about 14-15 months by then and of course they refused to do anything as it was "past their warranty date". The day before the hearing, they contacted me to say they would either repair or replace it. Turned out to be a minor issue where a small piece of plastic had dislodged inside the case, which was blocking the connector and was easily fixed.
If they had agreed to look at it initially, it would have saved both them and me weeks of backwards and forwards hassle, not to mention my DT filing fee.
