Happens to me but only in areas with a weak signal (NYC).
In strong signal I never lose a bar. At home, which is usually a dead zone - I was surprised to see so many bars with the new phone. But if I do cradle it with my left hand, the bars disappear completely within a few minutes.
But I cannot replicate it reliably elsewhere.
- rbanffy 16y agoIf I remember my RF classes, it will happen when there is one antenna in the region the phone is. If there are more antennas in different directions, roughly with the same power, the effect should be much less pronounced. Radio is... complicated.
- jarek 16y agoIf I remember my networking classes, a GSM device is normally connected to a single BTS (tower) at a time. (Hand-overs between two towers are the major exception, and they're very brief.)
- rbanffy 16y agoIf your hand blocks the signal of one tower, the phone will switch to the next that is probably not in the same direction as the previously best one and signal strength will, hopefully, not suffer as much from your hand.
