I spent along time to speaking to a number of what I can only describe as idiots, i even offered to show them a video of the problem... "oh sorry cant do that sir.". I went to a samsung official service centre first to show them 'live' the problem, they said yep screen needs replacing. Problem is the service centre has a lead time of 4-6 weeks for a new replacement screen. So they suggested send direct to Samsung..... problem is you cant speak to the engineers to tell them the specific issue. The customer disservice and tech nosupport people take copious notes on the problems but fail it appears to communicate it to the out sourced engineers in Norwich. I'll just keep sending it back by courier at their expense until they actually acknowledge the issue. If anyone gets theirs back successfully repaired please let me know so we can refer to it when talking to the 'wall' that is Samsung UK.
