@Jez your last post almost made me think you're trolling. But I think I know your problem. If the dates shift to random dates and times, it means you may have accidentally triggered a soft reset. If you do that, you get old messages returning to your phone as new, but they will stay at their relevant dates. For example, a text from 18/10/13 may return but it'll stay at that date since it,is not actually new. If that's your issue. Then its easily solved, ignore them. If not, post a screen shot. Start/Home button and power button in 8.0. In 8.1 use that same combo and it'll tell you the right one. The forum has facilities to upload pictures as well. That's the only way we can help you
