sorry I can't post links quite yet, add this onto the end of youtube.
It better not be like this when I pick it up Sunday.........
wow. i really have to wonder what he did to make it look like that.
When losing reception, phones don't go 100%-0% in a split second.
I bet he's just going for ratings after the whole iPhone mess.
Also, i can assure you that it doesn't matter how you hold it, even if you bury it in your hands from all sides, there's no catastrophic signal loss.
Mine has that problem. Full signal. Hold on the phone down the bottom and it drops down to 1 or 2 bars. As soon as you let go of the bottom, back up to full bars.
Signal loss when covering the antenna area is not a "problem", it's the laws of physics at work.
1 bar is totally reasonable, and depending on signal quality, 2 as well.
But going 100%-0%... that's pure BS.
I think this appears only when in 3G mode.
The VDO might not be telling the whole truth. From a user point of view, I have never seen signal dropped drastically like that.

I think it would still appear in GSM -mode, but the signal drop is nowhere near the amount when using UMTS.
Mine does it as well, in 2G and 3G, drops from -111dBm to 0dBm
My blackberry bold 9700 lose some signal when i cover the bottom. Every phone lose some signals when cover the bottom.
i can confrim this also happens with my Samsung Galaxy s aswell, and to those who say this is normal and happens to every phone, then you are wrong, i have a bunch of old nokias and NONE of them lose signal no matter where you hold it. the phones i tried it on are, the e71, 5800, the 6220 classic and the 6630. none of these phones loses any signal when gripped from anywhere. im so disappointed in this phone now

Yes they do. It's physically impossible to make an antenna that doesn't lose signal when covered. You can code the bars to show the signalstrength any way you like though. If I code the bars to show 4 bars 1-20% and a fifth at 20%-100% you'll very rarely see less than "full" signal.
Nokia is always been the best when it comes to reception quality. Am happy with my GS signal quality.

i tested those phones, i covered them up entirely with my hands, and there was no signal loss. it stayed at 5 bars. and its not a matter of coding since even with one bar i get good call quality.
but as Hassan said, nokia have always been very good with reception quality. and maybe i am overreacting since this is the first time i have come across this, having had all nokias before and this is my first samsung/android phone. but that doesnt really mean its acceptable, i cant get a decent signal when i hold my phone, at first i thought it was the network, since this was a different network than i was with before, but now that i have tested it and this happens, i cant help but feel like i have been screwed over a bit. going from 3-4 bars when not holding the phone to it dropping to 0 is not something i like in a phone
btw, it's best to know the difference between "no bars" and "no reception".
In contrast to most phones on the market, no bars at all means you have minimal reception.
It is still possible to make calls like this.
When there's absolutely no reception, you'll see a circle with a crossout line.

Ok, now read this carefully: Just because the bars don't go down doesn't mean you don't have any signal loss. You get signal loss on ALL phones when covering the antenna. You having 5 bars doesn't change that, it only tells us that the signal loss isn't severe enough to show on the display. That IS a matter of coding.
Obviously there's ALSO a quality difference. Depending on what transmitter/receiver is being used, the quality, location and size of the antenna and whatever will affect the quality of the signal. Some hardware have less signal loss than other when being covered, but fact is the signal loss is ALWAYS there regardless of the number of bars Nokia, Samsung, Apple or Anheuser-Busch brewery decide to show for whatever signal strength.
You can kill your data connection by covering the antenna on the GS...
Try with the speedtest app. Especially upload _WILL_ be killed proper, when the antenna is covered.
I put some standard kitchen aluminium foil between the phone and the backcover, It still drops bars, but uploading works a lot better.
its fine, i take it back now anyway, turns out i was right the first time, it is just the network. i lose bars even when the phone is sitting on a desk. and when i say lose bars, i mean the bars will actually fluctuate randomly, from having full bars to no bars, then back again, when the phone is in a stationary position on a table, near a window. it just happened to be coincidence that when i was testing it the timing was close enough for me to blame it on this. my apologies
Why is it most of the reception issues are in the US? I don't hear anything for Iphone 4 users in Japan and I'm using Galaxy S in Singapore, no drop calls, no drop signals blah blah. I think it is the network not the phone!
Oh noes, the world has come to an end, flee for your lives.....
If you are seriously disappointed that a phone made by imperfect people is not "perfect", then plz just return it and don't come back to this forum.
Unless you are getting dropped/crappy calls all the time, then wtf are you people complaining about? This forum is full of whiners.
Not as much whiners as hysterical people.
I can understand it a bit, since this isn't exactly a cheap phone, and is supposed to be one of the best (if not THE best) devices around.
The thing is that every time a POSSIBLE issue pops up, everyone start going crazy like "OH MY GOD IT'S 100% A PROBLEM THE PHONE IS NOT OK GET ME A DOCTOR"
Instead of, let's say, inspecting the matter rationally, and seeing if there's really a problem.
The Galaxy S has an almost full plastic body. There's no way it could share the iPhone's antenna problem, since the antenna is not exposed to our hands.
That video looks like an attempt to pull attention, for whatever reason. The only way i manage to replicate his results is by putting tinfoil on the back of my hand (which kind of leads me to think- we don't see the back of his hand even once in the video, nor there is sound, so possible raffling cannot be heared)
And even then, the results are not as drastic.
Everyone should calm a bit down and enjoy the device instead of inspecting it under a microscope for problems.
If a problem that affects your use somehow (e.g GPS, lags) appears, THEN do the complaining.
There are some videos floating on youtube showing Samsung Galaxy S Vibrant and Captivate having " death grip " , same as suffered by iphone 4.
you can check the videos on youtube
Samsung Galaxy S Vibrant and Captivate has internal antenna apparently located on the back of the phone, towards the very bottom edge. Can any1 here confirm me if Galaxy S is suffering from same issue
Any1 here facing this issue or its just a Apple fanboy gone crazy.
hi
i have used my phone a lot.. and i have never ever experienced this!
-TB-
No matter how many different ways I try holding my phone, I can't get the signal to drop.
it is yet another attempt from jealous iphone4 owner trying to make the SGS i9000 / HTD Desire / Moto Droid X looks bad
LOL
I've seen the videos, but I'm unable to replicate the behaviour..
Tried covering it completely with both hands in various ways, i can never get it to drop more than a single bar.
I did notice this the first day I received the phone: signal level drop from 4 to 1 or even zero bars when touching the entire bottom of the phone....doesn´t happen all the time, sometimes the indicated signal level stays the same....couldn´t figure out a pattern yet.
However, I have not once experienced a dropped call.....worst thing that ever happens is that the signal switches from 3G to GPRS - but then I have 4 bars again....
Can live with that....
I can easily replicate it with both my SGS phones when placing my palm over the back of the phone. This is in 3G mode and I haven't had any dropped calls yet so I'm not sure if it's an issue.
the only place i can replicate this "problem" is when i'm inside a subway station or inside a shopping center with too much metal beams.... say places like walmart and homedepot
by the way we do get cell signal inside subway stations, just weak.
so for reference a normal sony or moto handset non smartphone will be able to make a call perfectly fine, but when i was using the Treos I was never able to get a good signal
however when i upgraded to the HTC Athena i was able to make calls inside the subway station, now with the SGS no problem at all
Yes, I'm able to replicate the signal drop just like what they show for iPhone 4 in poor reception area only. I can also make the call drop out all together if the signal is already bad enough to begin with.
Note that in strong reception area it is also not possible to replicate the signal drop on iPhone 4, as shown by many YouTube videos, even if you do a death grip.
It's law of physics.
This issue does not bother me because I'll always use a case for my SGS.
All smartphones have this problem, didn't you guys listen to Steve Jobs?
lolz
yesterdays event was another publicity stunt by steve jobs
Hey now don't confuse this with the iphone 4 issue The difference here is the sgs doesn't do this by just bridging 2 pieces of metal, i.e. placing a single finger on the phone. You need to block the whole signal by covering it. I really doubt a case would have any effect on this as well. We are talking laws of physics vs a simple design flaw.
Cant really replicate it, but it can be a just signal representation bag.
I notice that sometimes I have like one bar, but if I go into setting and look at signal strenghts it can be exceptionally strong at the same time.
This just in..
Well... I put mine in a ledshielded box, padded it with sealhide (cause in Norway we have that laying around..) and swallowed it whole!
Bluetooth -> Working fine!
Camera -> Working Fine! (impressive really!)
Reception -> Working fine!
Todo:
* Testing swype whilst death-gripping the bugger!

and some basic common sense
of course it seems like that is only applicable to people who are intellectual enough to understand physic of radio waves and its interaction with the environment.
I think there has been an explosive growth in the level of public awareness concerning the effect of environment and human hand on cell phones after the iPhone 4 issue. I didn't realize my old phones had the same problem until I started testing it both good and bad reception areas. Then I searched in net and found examples after examples of videos demontrating th problem on other phones posted ages ago.
..hmmmm.. interesting.. I tried my best to replicate the issue..
..and yeah.. i can make it lose signal strength.. down to no bars..
..here is where the problem arises.. i can still make a phone call to my GF..
..nope, i didn't use just my left hand to cover the back side of the phone..
..i used my entire 2 finger and palm.. so the answer is, it doesn't have the iphone 4 flaw.
..lefty? righty? no problem, you can hold the SGS both ways and will never drop your call.
..hope this clears out all those who is trying to make a bad press out of the SGS..
Indoors, with my back to the window and my body kinda shielding the phone, I can make it drop from -81 to -97 dbm, by covering the entire bottom back of the phone. I can make it drop down further to -105 dbm by also covering the bottom front. However, both those ways of holding the phone are unnatural and if I turn around and face the window(phone infront, still held between my two hands) it shoots back up to -81 dbm.
So, is there a problem? Not as far as I can tell. As long as I hold it normally it's unaffected.

Actually I think SGS's problem is even more serious than iPhone 4.
I can reduce the SGS signal by 30 dBm consistently at home by merely placing it on my palm without even griping it. With iphone4, I think Anandtech's test reduce it by only 24dBm by death grip or bridging the metal. I have got a crude video showing this if you want to see it, but you should be able to replicate it yourself.
Is it just me or is anybody elses Antenna Strength all over the place. I almost feel like I purchased a new iPhone 4 with an antenna problem. I'm not sure if its my local tower or what. I can put the phone on the table and watch the strength max out then I can pick it up and watch it dance around from full to well nothing.
Take my fingers off the chrome outer ring and balance the phone on my palm and watch the strength climb.
It was delivered today, so I haven't really played with it a lot. I can tell you that my 3G signal is horrid, but was fine on my G1. Its almost like I gained an awesome screen and lost signal in the process.
I am inside, but never noticed that kind of activity at all with my G1.
Play around with it a little more and see if it has any effect on your calls. Don't judge purely on the signal bars.
The bad 3g reception you mention is concerning though.

The bars are -15dBm off to actual reception.
Yes, my signal strength seems to jump all over the place as well. Hope it can be fixed with a software update.
some thing here im about to get new one maybe tomorrow
of course were not 100% sure yet but we think the bars aren't reading correctly although covering the bottom of the phone were the antenna is there will naturally be signal loss does it on my tp2 as we'll...
i have the same problem its weird but manageable i tested my phone to the iphone 4 and my phone loads web pages faster streams videos from the internet faster and connects to youtube through the youtube app to play videos faster and seems to be faster all together only downside is the iphone 4 has the ffc and higher resolution but thats it i can deal without that
i always say forget the bars, can you make a call Lol
I have been making calls on mine while showing zero bars. No real reception issue. I just ignore the bars.
Yeah, don't go by the bars at all with this phone. Like above, I've had zero bars, and no issues here with calls or browsing the web.
I wouldn't ignore it completely...
I've had a few dropped calls now from the attenuation and frequently have my data freeze up on me when I hold the phone. The signal isn't terrible where I live, I never had dropped calls on my G1 or my Wizard in this location.
Unfortunately it isn't something that is fixable, it's just crummy placement of the antenna.
I held the phone in a death grip with my right hand until it displayed no bars, but it didn't seems affect my 3g. I did a speed test and I got 1.25mbps down and 0.3mbps up, which is pretty normal in my area. I did a second test holding it with my left hand and I got 0.99mbps down and 0.25mbps up. A third run while covering it up with both hands did have an affect, but who really does that? It showed 0.6mbps down and 0.15mbps up.
I haven't tried calling anyone under those same conditions, so I don't know if anything is going on there..
Ive had spotty 3g at my house since i got my phone. Most ive seen is 2 bars. Noticed tonight i left my phone on table and came back and i had full bars with 3g.
Picked up phone like i always and hold with left hand it drops to 1 to no bars. So i hold the phone with right hand i get stronger signal, left hand weak...
Im guessing the antenna is on the left bottom side of the phone apparently covering it up drops my 3g signal significantly, going from full to no bars just by covering left corner ...anyone else?
Not really complaining because i still connect 3g fine but i do drop to edge allot if im in certain rooms and phone calls never drop just curious of maybe a solution or whatnot
I looked on youtube and found this but you dont have to hold phone like this. just palm it with left hand
http://www.youtube.com/watch?v=vefQ4I2wOXs
And sorry if posted already i could find anything on this here
Happens here too. Funny thing is that I have case on it. One thing those in the youtube comments are mixing up and not understanding is the signal strength. I wish they were more smart people in the world lol..
Anyway what I am getting at is that this happens with all Vibrants, it just depends on your current signal strength in dBm. For example, if I'm inside with around 4-5 bars, around -81dBm. Then when I grip it, the signal will go down by -20dBm or more resulting in two to three bar lost. Where as if I'm outside with around -51dBm and do the same thing. It will result in the same -20dBm but you won't notice it enough because the bars don't start to go down until around -89dBm or more.
* The lower the dBm, the better your signal.
* It was the same issue with Nexus One.
* The design of the phone is causing your hand to have more of an effect on it.
If anyone want to proove this case. Just get two Vibrants next to each other in the same area and do the hand thing.
Yea see i never noticed this with my N1 But yea what your saying makes scene.
Its not a big deal i still connect avr 1mbps with weak signal but found it odd
Yea same here. I do admit the signal is even more sensitive than my n1 was though. Oh well I guess this is just one thing we have live it until a better phone comes again.
Shouldn't 2.2 come with an updated radio and if so maybe it will help
It might make the radio use more power from my experience but this isn't a software issue. Though speaking of software, right now the dBm read out and bars are off by 5 or so dBm. So when we get the 2.2 update we should see the proper signal read out which will appear stronger and it should be more stable as well. Either way, our hands will still be able to affect the phone. Just like any other phone but more drastic with the Vibrant, N1 and iPhone 4.
The bars are generally useless and I don't think it's really an issue unless it's actually dropping the signal. I have zero bars of 3G all the time, and I still get full speed. The difference between zero bars and zero signal is rather large, IMO.
If the signal attenuation from holding it causes you to drop 3G altogether, well, I feel for you. It's never happened to me, and I've done all kinds of grip experiments to see if I could make the signal attenuate.
To go on, the Vibrant has the best radio of any phone I've ever used. The test for me is whether I can hold signal in my building's elevator. Virtually every phone I've owned (and most all my friends' phones) dropped signal as soon as the doors closed or shortly after. Prior to my Vibrant, the champ was my Blackberry 8820, which could hold signal for about two floors before cutting out. The Vibrant? It may drop to EDGE, but I still hold some kind of signal all the way down, which is amazing.
That something I notice the first day I got the Vibrant , did not have that issue with other previous phone in the same spot... if I put the phone in a table it gets full bars.. once I pick up the phone it goes back to 2 bars... the only way I get full bars is if a hold the phone just from the bottom.
I'm going to have a seizure if I see another one of these threads.
-81dBm is an obvious flaw and should be completely disregarded UNLESS you're off of JFD or anything based on JFD. This phones reported signal strength refreshes FAR more often than nearly all other Android phones on the market. Motorola on T-Mobile being the slowest to refresh any signal changes.
The bars are wrong and very inaccurate. Do a search. Update to JI2 or JI4.

Ok so yesterday (in Sydney, Australia) I returned my HTC Desire HD after I was facing poor reception when compared to 2 other phones used in the same room of the house. I did carry out the factory reset as suggested by HTC and also wiped the SIM cards clean. For the tests I used a Nokia 6120 and a Sony Ericsson k530i. I also used SIM cards from 3, Telstra and the one that came with the Desire HD from Vodafone. In all the tests the Desire HD had significantly worse reception (at least if the reception icons are anything to judge by).
Yesterday Vodafone replaced my Desire HD on the spot as I was within 28days of purchase. At first I seemed to think the reception was better on the new phone however this was with the phone laying on a box and not touching it. As soon as I picked up the phone reception became lousy again like my previous Desire HD. After reading comments from other users on this site regarding the antenna being in the cover plate at the bottom I tried holding the phone in different positions to see if this bottom cover plate really did affect things. The two videos linked to here show my findings using the brand new replacement phone I picked up yesterday. Also in the second video is shown if a factory reset or a gel case changes this isse.
Now that I've got a better understanding of what is causing this issue I will contact HTC again to see what they say about it. I'll keep you updated. Please post feedback on your phone including what carrier & country you are using and what ROM and radio version is loaded. Thanks
Here are the two videos I made:
http://www.youtube.com/watch?v=6_ljHtUMOH8
http://www.youtube.com/watch?v=Nr16fGAVzQg
Okay I've contacted HTC in Australia and the person taking my call has looked at the two videos. He's said he has documented the issue and will forward the videos on to the HTC engineers to have a look at. Will let you know if they contact me with any updates. Feel free to contact HTC if you find similar issues with your phone. I would think the more people reporting this to HTC, the more importance they should place on trying to fix this issue.
Mine id exactly the same. I already noticed this since last week when I got it. Just dont hold it at the bortom.

AHEM. bit sounds like someone i know.. may be Stevey ..
But yes when reception is low, take your hand of the antenna at the bottom. I own a K530i too, where antennae is at back. I will get poor signal, if i hold it in particular way or if i keep it in cushion or so. but K530i antennae is ergonomic to hold but desire hd is placed right at where my palm holds it. this happens with WIFI too when i hold my fingers covering the side. but again its bearable. lets see how it holds in the long run.
At least the DHD, is ambidextrous. You can hold it with either hand just grip it in the middle. Compared to The iphone 4 which has crap signal when used by right handed girls. Lol lol lol.
Well, never had this problem even when I cover the bottom part the signal just drops 1 bar and that's it, no problems with the signal and whatsoever.
To the OP, just wondered what build no. and baseband is on your phone???

There problem is for an amateur like myself posting youtube videos is that if I don't decrease the exposure then you cannot see clearly the reception bars especially when I look at the backlit screen from the Sony Ericsson. I wanted to be sure most of all you can clearly see the what the phone screens are displaying.
Secondly please look at video 2 in the link it clearly shows how the Desire HD works in my experience in a case. Bascially a gel case solves nothing in my situation or at best maybe only delays by a few seconds the reception loss when holding the bottom.

Please look at video 1. It clearly show the software information page in the video which shows the ROM verison, radio version, kernal version and baseband (or radio version) from the stock Vodafone Australia ROM that came preloaded as of yesterday January 23. I don't believe recent radio or ROMs fix this issue as SWIM loaded 1.72.405.3 with the latest radio his phone to try to solve this issue, that didn't fix it so SWIM then tried around 4 different radio versions including the latest "test" release from UK and still no significant improvement. I'd be happy to hear other's feedback on this and what ROMs and Radio versions they use and if any real improvement. I will make clear though that with my brand new phone, it is stock and unmodified.
I mean no disrespect guys when I say this, I'm happy to take constructive criticism and feedback just please have a look at the two videos first and consider everything explained and put forward before posting a quick response.
As I mention in the video this issue is not as bad with Telstra and 3 SIM cards in my room as they seem to have better reception and don't drop as many bars (but they still do drop bars) holding the phone in the "death grip". The worst is the included Vodafone SIM card which the phone is on a contract with and doesn't get completely full reception before holding the phone as shown. I would imagine that the same scenario would be replicated elsewhere. Find an area where you don't get full reception and see how much it drops when you hold your phone like I have in the video. Again this is going to most affect data while browsing the web ect rather than calls where you are likely to hold the phone differently.
I don't want to start a war or get people upset here. I love the Desire HD and Android. I've paid for a long term 24month contract and I plan on keeping my phone. I'm only just surprised to find out this issue and I hope HTC will take it seriously to try to find a way to help out with solving it. Take care guys. Again if anyone else wants to alert HTC to this issue I think they will be more likely to treat this with more importance. As present HTC Australia seemed to say they'd heard nothing about it and played it down a bit.
Ok, you say the recpetion is worse than your older phone are you actually measuring the recpetion or looking at the bars?. More importantly does it actually result in dropped calls? I believe the issues with the iPhone4 (and if apple are to be believed all phones in the world released before it) where that the bars are only a vague representation of signal strength and that if held wrongly it dropped calls.
I don't pay enough attention to the signal bars, but certainly my ability to make and recieve calls is no worse than my previous HTC Magic and better than my wife's iPhone 3g
Just tested on my phone and here are the results... If i push the bottom of phone to my palm the bars drop from 4 to 2, when holding it in such way that palm covers the bottom bars drop from 4 to 3.... When holding it normally i have full bars, so i dont really see a problem...
Just adding my 2 pence, prior to updating my Radio I would get low or no signal at home. Probably the only draw back of living in rural Wales.
Now after flashing the latest Radio 26.04.03.30_M, I get a solid 3 bars 90% of the time.
No new cell towers have been constructed, the locals would go mental! In essence what I'm trying to say is, try an update your Radio.
Ensure you follow all guides to the letter.
Still no response from OP, as to whether this has a detrimental effect on real world reception i.e dropped calls, so as to whether this is an actual problem at all!
Edit: I assume from the resounding silence, that there's is no actual real world effect?... Nothing to see here move along please!
^^ I'm sorry I cannot answer that question as ever since got the phone with this SIM card I've been waiting for Vodafone to get back to me to change over my existing phone number so I've put on hold to use this Vodafone SIM card to make any calls. I can't believe that many years after the Australia wide (I believe government) policy to be able to keep your phone number that Vodafone are making a stink about it being such an issue to swap my number over. So in short I haven't been using the new SIM card and only been using Wi-Fi because I want to wait till it's transferred to my old number. I would imagine holding the phone vertically as shown that web browsing on zero bars wouldn't be great. If someone could test this googling net speed test with the bottom held and then without the bottom held I would be most grateful. I would also guess that once I move to an area with even less reception that data would drop out completely. Again this is just my educated guess. Others will probably have more experience on this.

The bars cannot be trusted and that's why we have a little thing called FieldTest. Dial *#*#7262626#*#* and you can see the actual signal strength in dbm. When completely covered and the palm pressed to the antenna the signal drops 7-10 db which should not be a problem. I normally hold the phone a little higher, covering only a small part of the antenna and the signal drop is even smaller - like 2-3 db. That's for WCDMA, for GSM frequencies it should be even more negligible. Too lazy to test it though .

It's about the same with GSM at least for me, which to be honest isn't a worry, so again I don't see this as being an issue in real world use

Some side-by-side comparison with the iPhone 4
Signal strength with the iPhone is ~5 db worse than the DHD. Both phones laying on the table so no touching whatsoever. When touched (with just one finger) at the "sweet spot" (bridging the WiFi and gsm antennas) the signal on the iPhone drops like 15-20 db. Both phones are in WCDMA mode.
Again I normally hold the phone higher than the cover by the sides of the phone. Unfortunately with the iPhone my ring finger goes exactly where the most trouble is caused, but if you ask a certain someone that's because I'm holding it wrong

I read this a few days ago. It may prove useful repeated here.

hello,
i am from austria europa and its the same
when i hold the handy with my fingers only on the top i have 4points
when i hold it with my right hand i have 4points sometimes 3
when i hold my handy with the left hand i have 2 points
i thought the last week.. why i have ever a problem when i call out from here ...never i had it with my nokia n80.
right now i know it..... super work from HTC... siro points for her
it was my last HTC handy for sure... also some others as
incoming call display doesn't indicate that a call is forwarded etc.... but thats an other story
tnx
cqf
Same here.
When I hold the phone with my right hand it drops 1 bar (around 6db in FieldTest)
When I hold the phone with my left hand it drops 2-3 bars (around 12db in FieldTest).
When it poor reception areas (around 2 bars signal) holding in the left hand it switches from 3G to 2G.
I think there is definitively a signal problem, especially for left handed people.
It would be nice to gather more impressions.
