Hi guys, I've been using my K800i (on Vodafone) for about a week now and I've noticed that the signal strength indicator keeps moving about all over the place. One second it can be at full strengh (5 bars) and then it will gradually drop down one bar at a time. Sometimes it goes right down to nothing, and then suddenly all bars come up in an instant. (This is happening when the phone is not being moved around, i.e. just sitting on the armrest of my sofa.) A friend in the office also has a K800i (on Three) and his phone shows all five bars with no movement at all. We sat and watched both phones: his didn't change but mine went from 4 or 5 bars then slowly down to nothing, to the point where the screen displayed 'emergency calls only' and then suddenly all five bars came back up again. Just wanted to know if anyone has any ideas on how to test things. Is this a Vodafone thing, or is the phone faulty? Any help or comments greatly appreciated. Thanks. shr.
