[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?

-70dBm to -79dBm no hands -77dBm to -81dBm in hand.

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?

.... Why exactly are we placing the antennas at the bottom of any phone.. I mean you hold the phone on the bottom, like seriously? Is there a reason for this o_0

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.

Phone reception issues

I have a Samsung Galaxy S on T-mobile in the UK and I find that the phone signal indicator jumps around all over the place depending on if it's being held or small movements in it's orientation.
In a worst case scenario I can have the phone showing 3-4 bars of signal with it on a desk and then if I pick it up and hold it a couple of inches higher than it was the signal can drop to 0 or 1 bar. It often then comes back after a few seconds.
Coverage here isn't the best and it seems that I can usually still make and receive calls and it doesn't actually go out of service but is anyone else noticing the same?
The same happens when it's forced onto 2g only but not quite as badly.
I also have an HTC Desire here too and that seems to be much more stable.
The GPS on the other hand which a lot of people are complaining about seems to pick me up with ease. Even sitting on my desk inside a building it quickly locates me to within a few metres.

I've owned and used an iPhone 3G, Nexus One, and now the Samsung Galaxy S.
In my location on vodafone the SGS and N1 are equally "poor" on 2G/3G - meaning I have to find a spots in my house in the countryside to find a strong signal. In practice it's not been a big deal and once out-and-about both the SGS and N1 are fine for me. The GF is now using the N1 with 3UK without any complaints.
The iPhone 3G however would show a much stronger signal than either Android handsets (note I've used the same vodafone SIM in all these phones and the iPhone 3G was a factory unlocked import from Italy) - however the truth about why that was is revealed in Apple's recent press release about iPhone4 antenna issues - that is, they were using a bum calculation and displaying too many bars, so it only appeared to be a stronger signal when in fact I suspect it was exactly the same in reality as the N1 and SGS.
See it for yourself, Apple's engineers got it very very wrong and it's now biting them on the ass:
http://www.apple.com/pr/library/2010/07/02appleletter.html
"we were stunned to find that the formula we use to calculate how many bars of signal strength to display is totally wrong. Our formula, in many instances, mistakenly displays 2 more bars than it should for a given signal strength."
That makes total sense to me, so I have no concerns about the Android phones appearing to show a weaker signal in my gaff. The fact Apple engineers can make such an accidental "mistake" says a lot to me about their quality control, whichever way you cut it.

Interesting read, thanks for that, I hadn't realised they'd made an announcement on the problem yet.
The more I use the phone the more I find it works as I'd expect it to in the T-mobile coverage that I'm in it's just that it's a little alarming when the phone signal indicator moves around so erratically when picked up or moved even only slightly.
I guess I'll continue to use the device and just see how it performs in the real world.

Ha. I remeber when I first got the iPhone 3g. They were using the honest signal meter then. I was only getting 2 bars almost everywhere. Then came the software update and I had 4 bars everywhere. Now I still drop calls even with 5 bars.

Sorry to dig out a slightly old post but i'm experiencing the same thing. I'm also in the UK on T-mobile. The phone sits on my desk at work and randomly goes from 4 bars down to zero signal for no apparent reason.
I've had a G1 on T-mobile for the past 18 months and i've never had any reception issues at work so its definitely an SGS issue.
I could deal with the indicator going crazy but when it leaves me unable to send a text or make a call for a few minutes each time it zero's out its pretty annoying.

Same Reception Problem as iPhone 4??? link w/ vid

/watch?v=LROTHrTR92k&feature=player_embedded#at=22
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.

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!
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.
Regards

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.

Antenna issue

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.
