in my house, i get around 4-5 bars of 3G. referring to anandtech's study, that means that i am on the lower boundary of the 5th bar/upper boundary of the 4th bar, putting me approximately in the -94dB to -85dB. now, when i "death grip" the phone, the bars DO drop all the way down to 1 bar, as expected, but interestingly, they go all the way back up as well. i understand completely why the bars drop when "death gripping" (the signal gets attenuated by a max of -24dB), but what I don't understand is why the bars go back up. i am not changing the grip of the phone at all. if i hold the phone for about 15 seconds, it'll take about 5-7 seconds to drop the bars and then another 5-7 seconds to raise them back up. and once they are back up, they don't drop anymore when "death gripping" unless i restart the phone or reset network settings. so i just wanted to know what the reason is for this. i haven't really been getting dropped calls, so it's not really an issue, but i'm just curious as to the theory behind this.
