OMG! HD2 has same grip reception flaw as iPhone 4 - HD2 General

If you hold the phone in your left hand - just like the iPhone 4's "wrong" grip (your skin presses against the lower left side of the phone) watch reception bars go down 1 or 2 bars. The longer you leave your hand there, the more the bars go down. Release and they are up again. Tried it with and without a case. Same issue.

Just because it happens to HD2 does not necessarily become a problem.
I could also reproduce that on my iPhone 3GS and 3G in some location but not in all locations. I didn't even realise this until people start complaining about iPhone 4. To reduce the signal, i have to grip it (without using a case) very tightly without lettting go for a long time. If I periodically relax my hand as I would in normal usage, then signal won't go down. As this is not the way I normally grip, and the fact that I've been using my phones for so long without even knowing there is a "problem" probably means that I have nothing to worry about.
Then, I searched the youtube and found out that it is also happening to Nokia phones:

Nokia is trying to fool everyone by saying that users can hold their phones in anyway they want, but this is simply not true. See this:
http://www.appleinsider.com/article...at_iphone_4_death_grip_gets_called_on_it.html
Haven't got an iPhone 4 yet, but my impression is that this issue is more pronounced with it. IMO, although it can be easily fixed by using a case, applying a sticky tape or nail polish over the lower left half of the antenna, Apple would definitely need to address this issue so that out of the box the extent of signal strengh reduction is minimized.

I didn't say it was a problem. I was just shocked to find it out after all this time I had it and never knew. Hence the OMG!

I think the phenomena is likely to exist with every phone, in certain locations, with certain hand type, but owners of the phone may not notice it unless they deliberately test it out. I could only produce that phenomena is one part of my house but not in another. Just like half the iPhone 4 owners were not able to reproduce this problem while about half were able to. My guess is that it has nothing to do with manufacturing defects, but simply a case of the location, orientation, and body type.

There have been discussions about that at the beginning on the HD2. The antenna is in the bottom part of the phone, between the bottom and the start of the metal cover, i.e. where your hand is (as stated in the manual).
The end word is that pretty much every phone on the market will have its reception drop a bit when you hold it.

FCC only allows the antenna to be located at the bottom of the phone, away from the user's brain. Also, the level of signal strengh must not exceed what's allowed. So, even if the manufacturer want to relocate the antenna to the top part of the phone so that user's hand could not touch it so easily, it would not be approved. Simiilary, even if the manufacturer could increase the signal strength, it would not be approved.

I heard that the fastest and cheapest way to solve teh Iphone 4 reception problem was to put a condom over it. They are cheaper than the bumper and are available in a varitey of colors and textures. The added plus is that you always have a condom handy should you need one

Classic Apple!
Let HTC and Nokia work tirelessly for years upon years only to one-up them with a bigger shinier version of a feature EVERY smartphone has had since 2003.
Sheesh.

Your recommendation would suit youself my friend. I'll use a nice looking case.

Basically every phone has way to hold it which will lower signal strength. With most smartphones it is rather easy. Most phones also have picture in manual how to hold it correctly. It's nothing new.

The HD2 issue your mentioning is a normal reaction to covering an antenna. This SHOULD happen in all phones since you are partially blocking the antena.
The iPhone 4 issue is not similar, if you go through this post:
http://gizmodo.com/5571171/iphone-4-loses-reception-when-you-hold-it-by-the-antenna-band
you'll see that the signal loss is due to connecting the left side of the antenna with the bottom by touching the left side and the bottom (left) portion of the phone. If you put a "Bumper", apple's term for cover, and then hold the iphone in exactly the same way, you will not lose the signal.

Yes, thats because the singal has to go through your hand, so it might lose a bar or two.
All phones get this.
The Iphones problem is not the same thing, it just hast he same result.

if i leave any phone I've ever had in pretty much any spot in my house the signal flutuates.
sod all to do with holding it.

just use a BT headset

anyone cares for some duct tape?
http://www.marketwatch.com/story/apples-latest-conundrum-duct-tape-2010-07-12?dist=countdown

lol... Snapperheads...
If you watch the iphone vid on youtube showing the 'making of' the phone you'll notice the alloy frame is the antenna... Covering it will help not to drop the reception... But having to have a cover to not lose reception is a joke...
As for the HD2, all phones held in a hand will have variance in reception... I tried the left hand thing on mine and it didn't drop a bar...

i have no problem with mine........may be the signal/reception from my carrier is really great unlike that in US.....

LOL good thing i'm not left handed

[Poll] Video of 3G/EDGE Switching Issue by moving your HAND

http://www.youtube.com/watch?v=x2g5J4qPp54
A video clearly showing the cause of the 3G/Edge switching, and quite "WTF" at that
Does your phone do this?
(P.S. You can access Phone Info like in the video to see your signal strength by getting AnyCut from the Market -> Long press home screen -> Shortcuts -> AnyCut -> Activity -> Phone Info)
Easier way to access phone info:
Open up the dialer, *#*#INFO#*#*
Is this really all that suprising? I'd put money on the same thing happening with most phones with the antenna in a similar position.
Not had any noticable problems with 3G in the UK.
After watching all these videos I started freaking myself out about the 3g issue, but then I realized that 1. I never did any of this and wasn't constantly checking my G1 to see if I was on edge and 2. the only time that anything close to what happens in that video (for me at least) happens to me is if I'm somewhere with spotty 3g anyway. I'm sitting at my house right now where I get great 3g and if I cover the phone with my hands I lose maybe 8db at the most. I think the rumors of the 3g issue are greatly exaggerated.
If your in a poor 3g area it will do this. And like dude above said it'll do that on most phones. I remember getting my tp it had in the instructions Something about not covering the radio at the top of the phone (tps was at the top). Now I'm on horrible 3 g area and tested this and it did switch back n forth while doing that, but it also does it to my tp2 also, so it gonna happen on most phones in bad coverage, now when I'm closer to a tower it wont do that...
Any phone will act like that.. most I mean.
In my house I usually have around -97 through -101 dBm (with the phone on my desk, no hands).
What do you guys see as your average signal strength?

Not had any noticable problems with 3G at home...may loose 1 bar once in a while.
wow, i just tried the exact same test and got the same results and i am in a very strong 3g area (tempe)...
You are covering the antenna - of course you are going to see a loss of signal strength. If you are in an area where that loss causes you to bounce to edge then you are going to bounce to edge. This will happen with any phone although it is more noticeable with smartphones in my experience due to the lack of an exterior antenna (perhaps you'd see the same with bar style phones).
The N1 happens to have the antenna at the bottom of the phone (maybe not the smartest placement) whereas many other smart phones have it at the top of the phone. Whether or not you get the results in the video merely represent your relative signal strength in your area.
I've been trying to force myself to use my N1 with my left hand more then my right to keep the singal strength up...seems to be on the bottom right of the phone...

Well, it's very natural to want to hold the phone at the bottom. So basically it's just bad design then?...
This strikes me as pretty much of a non-issue. Yes, human flesh is not very transparent to radio at these frequencies, so if you wrap a couple of centimeters of it around the antenna, you'll see a drop in signal strength. They have to put the antenna somewhere, so it's just a matter of putting your hand somewhere else. For myself, I hold the phone with my thumb on one side edge, my two middle fingers on the other side edge, and my index finger on the back next to the camera to press the earpiece against my ear. It feels very comfortable and quite natural that way, and it leaves plenty of air space around the antenna at the bottom. Holding it this way, I never have any signal strength problems or dropped calls.
There may indeed be some 3G/EDGE issues where the algorithm for when to switch isn't quite right; I can't tell about that because I only get EDGE inside my house and always get 3G outside my house, so I've never seen the flipping back and forth that seems to be the basis of most folks' complaints on this topic. I'm just not terribly impressed by an experiment showing that wrapping your hand around the antenna causes the signal strength to go down -- I mean, who'd have expected that? ;-)

Yeah, it is definitely a design that is not the most friendly, but the N1 is not the first phone to do it and likely won't be the last.
The video in question doesn't "show" anything new other than human flesh isn't very transparent to radio signals - anyone in a weaker coverage area can replicate the video while those in very strong 3G coverage areas (where you get a strong 3G signal not where the map says it's best) likely won't see any drop to edge unless they have hulk hands.
This doesn't appear to be any sort of newly discovered build issue (to be fair the manual that comes with the N1 states to avoid placing your hand/fingers on the bottom of the phone, with illustration on pg 12 ), rather it's a flaw in the design of the phone due to the location of the antenna and people's tendency to hold the phone covering the antenna.

The point isn't that [wrapping your hand around an antenna decreasing signal strength] is new information.
The point is, why does this happen so EASILY with the Nexus One?
And why has this phenomenon never appeared in the news so prominently for any other phone in the history of mobile phones, as it has with the Nexus One? THAT is the issue.
Also, the Motorla Droid has the antenna at the bottom (the bottom lip), does it not? Why doesn't that phone have any issues?

I think it's probably because there actually was a problem with the software originally released with the N1 that caused it to switch between EDGE and 3G when it really didn't need to, and the resulting hue and cry about that over-sensitized people to this particular non-issue.

Well there could be a few things off of the top of my head (if it has the antenna at the bottom)
Motorola may have wired other surfaces to act as additional antennas (as apple claimed to do with the iPhone 3G) on the droid.
If they did not then it's entirely possible that the N1 may have poor automatic gain control set up currently while the droid appropriately boosts gain when the signal drops.
When I cover the back of the antenna and hold it covered the signal drops out of what should be "acceptable" after 10-15s. I don't lose 3G but there is a significant degradation in signal (down to -93 dBm to -95 dBm). Perhaps the ACG controls aren't allowing gain to be boosted high enough for the radio to get a stronger signal or the thresh hold of what is "acceptable" is set too low.

iPhone 4's "death grip" on Vibrant?

http://www.informationweek.com/news...html?articleID=225900042&cid=RSSfeed_IWK_News
Anyone see this happen to there phone?
Holy crap it's true, but you have to hold it in such an awkward way that I doubt I will be able to reproduce it in real life use.
I guess The Jobs wasn't lying about other phones having the issue.
I heard about this Via T-MoNews... I have tried to emulate it and I will say this:
It is true. When I held the phone "Death Grip" Style.. I lost 'bars'. But 'bars' mesning the physical representation of bars on the screen. I did not lose and data speed, and i did not check to see if voice was affected, but i have been talking on the phone all day with no problem. I also tried this in my basement where i have poor 3g reception.
I think that this is an issue on the grounds of the physical representation of 'bars' on the phone may not be calibrated properly, but if anything, a fix would make the phone appear to have MORE service, and not less, like the iPhone.
Yep, tested a few times. It's true, but it's entirely a different issue from the iPhone4's troubles.
Basically the full antenna hump has to by lying flush against the palm of your hand and it has to be held down against the palm with quite a bit of force, basically an airtight seal. I don't ever see me holding the phone in this fashion, for any reason other than to test this.
I don't think anyone ever denied that every phone in existence has some signal drop when held in a particular way. My Vibrant goes from 4 bars to 3 when held deliberately attempting to cover the entire antenna bump, but I am inside an office building that causes AT&T to go from 1-2 bars to zero when not holding the phone at all.
I attempted the two handed airtight seal method and couldn't get more than 1 bar to drop.
I can see it now "Every phone is going to get this death grip test." Is death grip considered has holding it normally or covering everything? As far as I know, iPhone had a problem when you normally hold your phone with your left hand. I went outside and did the same thing since I don't get a strong reception in my house and it was fine. Now, if I hold the bottom of the phone, then bars drop, but that should be expected.
Another thing to mention here. In that link posted by the OP, the editor had no trouble with calls and etc on the iPhone 4 while the Apple's co-founder had a different experience according to an article posted by Techcrunch.
Yes, this is for all cellphones...for a tp2 if I hold it by pinching the top right corner....I loose 3 bars...but it is not realistic to hold it that way..
On the iphone they had the antenna swirled around the phone...thus it end up in the bottom left corner which you normally would hold...
That article is trying to cover for the iphone's design flaw in general..on the Vibrant and captivate you wouldn't generally hold the phone that way for it to matter...
Drop in bars, but no dropped calls. That is a massive distinction that the source article fails to mention. Vibrant FTW

That's the key issue - it's a non-issue for most phones during "normal use". You have to actually try to cover the exact area, which is not a normal holding position most of the time. That's not the case for the 4G, I've seen it happen when holding the phone as I normally would with my left hand.
I'm not trying to bash the iPhone because I do like the design overall, but the article seems to leave out some key distinctions that make the iPhone issue different.
That article is so incredibly poor. ^ hit on it exactly. These are NOT the same issues.
Let the thread die.. i do not like seeing iGadget comparisons on XDA.

I ran a speed test with and without the deathgrip on my vibrant (a 4 bar difference) and noticed no notable speed changes.
Holding the phone normally, with my palm about 1/4" away from the bump/antennae on the back of the phone, I definitely lose signal, 3 bars to 0 bars. I also definitely lose download and upload speeds(according to speedtest.net app).
Also, when I go to Menu>Status>About Phone and check the signal there, it goes from about -85dBm 8asu to 0dBm 0asu.
Why would any cell phone maker put the antenna at the bottom where it could easily be covered by the hand? Doesnt it make more sense to put the antenna at the top?

I don't know if it's "illegal" as in punishable by jail time, but I believe FCC regulations enforced on cell phone manufacturers mandate antennas to be on the bottom of the phone to increase distance to that grey spongy thing between your ears.
Has to do with exposure to radiation from the antenna.
What if you're holding the phone in landscape with your fingers going over the back of the hump? Does that affect data, speakerphone calls, or GPS signals?
I can reproduce signal loss cupping it in my hand but no call or data change. The iphone issue actually detunes the antenna.

Samsung Galaxy S - Death Grip

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!

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.

I have created a new topic as I feel this one is important and don't want it to get lost in the ether.
I've noticed if you hold the phone in a normal way and it doesn't matter if its left or right hand the signal and WiFi will drop , when you change your grip signal goes back to normal .

I can make wifi drop to 1 bar by holding the top half of the phone. Base of thumb on the volume control, top of thumb covering the power button and palm touching the camera. Releasing it, the signal will jump straight up. But who smothers their phone anyway?

It's not that simple. I'll bet there isn't a phone with an internal antenna that wouldn't drop a few bars anywhere when held in hand. Point is that the singal strenght in iphone 4 drops significantly more than in any other phone.
So does the DHD have the same antenna problem than iphone4? The only way to find out is to test in serval locations that will the DHD drop the signal when iphone 4 doesn't when the phones are held in hand. Comparing bars is pointless becouse it's calculated in so many different ways in various phones.
All phones suffer from this to some extent. The problem with the iPhone is that the metal part of the aerial is on the outside of the phone so that you are actually touching the aerial with your skin, which is why it's such as issue. At least HTC have a bit more design sense.

+1 The problem in iPhone 4 is due to the design of the phone - it uses the chassis as the aerial but the DHD is not designed to work in the same way.
I noticed that holding the TOP of the phone with your hand cupping the back causes WiFi signal to drop when in medium to low signal strength areas and also the Network signal to drop by up to 2 bars. Apple were keen to point out that many handsets have issues with signal degradation when holding the phone, however generally this is NOT while holding it at the bottom, the natural way of holding a phone.
So while the Desire HD will suffer a signal drop when held with your hand cupped around the top of the phone, it doesn't suffer the iPhone 'death grip' which imo is still a MAJOR issue with a handset that is perfect in many other ways. Put it simply, I've not dropped any calls with the DHD!!
Regards.
OMG I can't believe someone asking this question!
Next it will be someone reporting "Why can't I access the Apple app store on this device?!"
Your having a laugh aren't u ... hate Apple with all my might .. just concerned we would have same problems ! Hold my phone different so I don't

It's a good question and one I was considering asking myself after noticing it while browsing in bed. I sleep at the opposite end of the house to my router and can easily cut the connection while holding the phone at the top.
I think with the current trend of slimmer phones the issue will be highlighted more frequently as it is now a necessity to make use of the phone casing in regards to signal transmission. It's a known fact that the DHD unibody is part of the functioning antenna, so it's not suprising that you can produce the effect when cupping the phone.
Thankfully HTC have placed the module in the top of the phone and not the bottom like our good friends in Cupertino!
Nothing here when I try the methods mentioned. The signal stays very strong. It's been flicking between H and 3G but that's nothing to do with the phone, pure T-Mobile thing.

I have a desire z and just googled for this grip problem and found this thread.
I have quite a bit of trouble with my desire z, it drops two bars while calling. It even gets worse when you slide out the keyboard and start typing. The wifi and gsm/3g signal drops 2/3 bars!
This kind of sucks...
Has anyone had dropped calls due to this issue? If no, then there is no problem. Lowering the signal strength is normal, dropped calls aren't.

In my device there is a little signal drop, but no drop calls at all!
"Drop calls" are a trade mark of iPhone4. ;-)
No dropped calls yet but 3g/hsdpa switches to gprs when holding it.

Well that's still a connection I know that it's slower and that's something you can feel unlike switching a voice call from UMTS to GSM, but it's not a drop. The higher frequency of 3G is more prone to signal attenuation and nothing can change that.

Hi all from Russia.
I have the same problem.
When the phone is on the table, the signal level WiFi and GSM 100% (A router in the half meter away from me)
Whenever I put it on your hand or touch the side cover, the level of WiFi drops to zero and GSM is not as critical, but falls to 2-3 division
I'm not saying if I go into another room, where the signal disappears altogether.(WiFi)
Do you think that this might be?
Bad soldering?

Check if the battery cover is closed properly. In the room where my WiFi router is, the signal drops 1-2 bars but it's still strong. I've read some reviews on 802.11n routers that claim the signal is actualy worse if you are too close to the router (can't check this myself as I am with a 802.11g router).
Dude, I checked a hundred times that damn cover
in the next room the signal disappears altogether, although on a different device everything is fine!
I tried to switch the router in different modes, the effect is the same.

About the signal when holding the top of 6P

Is there anyone found the problem that when holding the top of 6P, Wi-Fi signal will reach a very low level or even lose connection? Is there any solutions? I think it is too inconvenient to play games or watch videos.
This problem is similar to the "death holding" in iPhone 4, I'm surprised that it happened on the Nexus 6P released 6 years later...

It is definitely real but just like you said it is similar to the death grip of iPhone 4. Unless you grip the phone hard around the top it has little effect. If you grip it hard you can essentially attenuate the signal to zero. Non-issue as far as I'm concerned. It has never caused me to lose signal significantly when using the phone in landscape for YouTube or gaming either. It's clear where the WiFi and other antennas are on the phone. Just don't hold it there. For once I agree with Apple - you're holding it wrong if it's causing you a problem.

Okay...... Maybe it is the only answer... It is one of the general problems on metal phones? If it is, I may choose a glass phone(like honor 8) as my next phone.
What!! I never heard of this issue on the 6P before, but sure enough... Full bars and then I wrap my hand around the top and watched it immediately drop to less than half way. Let go and it's back to full. Wow...

I would suggest that if you hard grip ANY phone where the antennas are then you will attenuate the signal. It may be a little bit less obvious with a glass phone but it can still happen. For example, the iPhone 4 as you said was the first phone this was noticed on and that was Glass design.
I would guess that you could probably also do this on a plastic phone, it's just not so obvious where the antennas are on plastic phones because they don't have a plastic antenna stripes.

I noticed it when I was downloading a game and in the meantime watching a video. Wi-Fi lost connection and it switched to LTE, when I had less than 50MB data at the end of a month. It cost me more 10RMB and scared me. If I didn't notice it and turned off the LTE soon, maybe I would lost all the money in my account...
Hahah mine does it on LTE also been that way long as I can remember. when I watch YouTube in landscape mode I have to hold it with my right hand so that my left hand doesn't interfere with the signal..
