From: zoara on 6 Jul 2010 14:07 Has anyone managed to compare two iPhone 4s side-by-side, one of which suffers from the "death grip" and the other that doesn't? I don't mean "loses bars", I mean it goes to No Signal and won't take calls. Or has anyone seen comparison videos anywhere? Trying to work out whether different batches suffer from the problem differently. -z- -- email: nettid1 at fastmail dot fm

I'm wondering whether or not shorting out the 'antennas' via fingers, water or a bit of wire makes any differnce, also in theory maybe a bit of wire soldered to the case/antenna might impove the signal. Maybe having a 1 metre bit of wire soldered to the iPhone will give a massive improvent to the signal and allow you to recieve signals from Aliens on those exo-planets they keep finding. ;-) > > -z- > > > -- > email: nettid1 at fastmail dot fm

Bridging it with a paperclip doesn't. Pass on the water thing as it's not my phone and I don't want to take the risk :) -z- -- email: nettid1 at fastmail dot fm

Which seems to show that it's a capacitance issue. Like the finger is changing the aerial response, rather that bridging the aerial elements. -- Peter

It's curious that it's so localised, though. I'm fairly sure that we tested holding it *near* the black bar but not *bridging* it, and it didn't trigger it. Bridging the top bar (the other one that isolates the two aerials from each other) doesn't trigger the effect, either. Not sure I can work that out. -z- -- email: nettid1 at fastmail dot fm |
