Before I exchange my phone again, I was wondering if there is 100% confirmation of this issue. I use my phone with WiFi in landscape mode, so this problem is really bothering me.
If you not having the issue, why worry about others?
I am having the issue. I apologize if I wasn't clear, but I had said that "this problem is really bothering me" as in it is literally bothering me.
No i don't have this issue. Can't even make it happen. If that's couse of the signal strength i have on the wifi's i use it on, who knows. But it's never been a issue here!
Can't say I've found it an issue but I don't use my phone in landscape for anything
Death Grip.
Hi OP, Ive had this problem when browsing in landscape, a certain grip can knock WiFi signal strength right down or if its already low completely kill it. Another thread on here advised
Settings - Wireless and Networks - Wireless Settings - Advanced - Tick Best WiFi Performance.
This seems to have made a significant improvement and TBH I havent noticed a change in battery life.
Hope that helps.
(Never had the problem WRT 3G/4G)
Third Sensation also has death grip issues, performance setting doesn't seem to help substantially. Bummer. I guess I'll just have to find an new handling position when reading.
no problems here, works fine

Are you using it in landscape mode and gripping the left side (near the HTC logo) with your left hand? Also, you must be a reasonable distance away from your router. If you are within 8 feet, the drop isn't noticeable.
When I first got the phone I was staying in a hotel. WiFi dropped constantly if I held the phone in my "normal" grip. Now I'm at home and I'm unable to kill it, no matter how I hold it.
Yeah I have the problem too when I use it in landscape mode sometimes it'll be so bad I'll be put on 4g thinking if I should replace it I also have the lock screen issue is there really sensations out there with absolutely no death grip?
Got my Sensation yesterday. Just tried the death grip test and can't make it drop below 4 bars no matter how I hold it. This is with "Best wifi performance" unchecked. Wifi Analyzer does show a drop in signal strength of about 20dB, but I never lose connectivity. Played a YouTube HQ video and it never stutters in landscape, with both hands wrapped around the phone. Based on the signal drop it's very likely that in a low signal location holding it certain ways would cause connectivity loss. But that's very likely true of any phone.
So, being conservative I'd say at least some Sensations with some routers do not have the problem.
Hi. I've heard that there may be a difference in the models. Some have 3 pins connecting to the back cover/antenna and some have only 2 pins connecting to the cover. If people could post if they're having problems and how many pins they have under their back covers there could be a link?
i just purchased my phone last Saturday, and i am already on my second phone. they both exhibit this "death grip" issue, and the problem is very apparent--enough to render the wifi useless for me.
it does seem to be based on the wireless AP though. i do not experience an issue at work, nor at certain public wifi points. however, my cheesy home wireless AP seems to have a problem, and i suspect most hotel wireless APs will as well. since i travel for work, this is a problem.
i was informed by a T-Mobile employee that this is a known issue with the first generation of these phones. phones manufactured after June 1st are supposed to have resolved the problem. i am currently waiting for their shipment of these new phones to arrive so that i can get a replacement to see if it truly does resolve the problem.
When I throw my gorilla grip on my sensation (just below the point of annihilation) I have no signal issues. No change.
Maybe only certain sets have the issue, because I haven't faced it at all. I browsed the web using WiFi and had no issues. I have issues with the signal, but that is more due to my service provider and where I work. Otherwise, no dropped calls and surely no deathgrip.
My Phone has the. Issue. When I hold it with a death grip, I can see my wifi bars going down. I don't know how it affects the practical use and the internet speed.

That would be 'signal attenuation' rather than 'death grip'.
I don't have any signal attenuation on my Sensation. It does not matter how I hold the phone. My phone is dated 6/6/11.
Sent from either my N1, NS, or Sensation4G....
My first Sensation had the best screen but the worst connection with the death grip. My second handset has the worst screen but the best connection with death grip. Much like ALL android phones, you always have to compromise with some feature/defect.

I've got a brand new Desire S and I love it. Fast, smooth, responsive. Battery life (OK, over my total 2 days of ownership only!) has been brilliant - 9% drop overnight for example.
I'm about to return it.
Why? Because of one thing that makes it almost unusable.
I am, of course, referring to the "Grip of Death" - as per the iPhone 4.
There are a few oblique references to this on the net, but I can't find any detailed posts.
Some mention has been made about this only being a WiFi issue, and it is true that WiFi is badly affected. However I also see 3G signal drops when I hold the phone in portrait mode with my hand wrapping around the base (as most people would in normal "phone" use) - which is, of course, where the antenna is (incorporated into the battery cover)
The WiFi drops on mine are tragic - I can be 3 metres from an access point and if you hold the phone incorrectly (!) the WiFi signal drops out completely and you are on 3G data. Even if directly under the AP you can easily get the signal indicator to drop from full to under 50%.
However the 3G drops are also bad. In my flat, which has a good signal, I can get to one or zero bars of 3G signal just by picking up the phone.
So I have a phone that is unreliable in picking up calls, switches to 3G data when there is a perfectly good AP just nearby, and is basically, generally unreliable.
It's a shame because, apart from this, it's a brilliant little device.
Am I the only one affected this badly? Maybe I have a poor example?
I have a case arriving today to see if it will help. Otherwise it's back to the shop!
hmm..you are the first person to report a drop in 3g signal
can any one else confirm this?
or is it just that the OP got a defective unit?
(i am unable to test as i still dont have my device yet )
I'm wondering if only certain phones are affected. Engadget doesn't mention it and this review specifically says it isn't a problem. It is a mixed bag of responses from posters here. Is it possible that Techradar got an early review model and the problem has since been fixed? You think HTC would comment one way or another since this could affect sales.
Just tried it on my DS, but the death grip does not influence my 3G signal.
With wifi on, I manage to lose only a little bit of signal while holding it in such an unnatural way that it will never occur using it normally.

can you try covering the back of your device as much as you can with your hands & test the wifi & 3g signal?
it would be very helpful for us
Covered the back as much as I could, no problems with 3G, Wifi drops to zero...

lol
but i hope htc does something like give replacement battery covers which fix the issue..because that is the only hardware defect that people are exaggerating about..
Ok, a few tests, as long as I still have it:
Portrait mode:
No issues in normal one- or two-handed operation.
As soon as something, e. g. my hand, covers the top plastic part at the back the wifi signal goes from all bars down to the dot, or disconnects entirely. I'm not so sure about the mobile signal, some of the time it drops to about half the bars it's had before, but with a considerable delay, and it's a bit erratic at the best of times, so it might just as well be other (environmental) causes.
Landscape:
I really only do this two-handed, with the left hand holding the phone, fingers bunched behind it, thumb in front, covering the HTC logo and first few mm of the screen; the right hand operates and/or stabilizes the phone.
This instantly kills the wifi stone cold dead. 3G actually stayed the same or got better(!)
To sum up: wifi is badly affected to the point of uselessness, 3G doesn't seem to be.
hmm..
can you try the wifi again in landscape? this time without touching the aluminum part of the phone?
(dont cover the aluminum part with your hand or any other item)

Actually, I don't see how that would be possible? Covering the top plastic part without covering anything else, I mean. I tried a few contortions and nearly dropped it.
Care to elaborate?
it is a bit tricky i know (dont drop your phone trying lol)
how about putting on top of two books?(such that the books only touch the plastic )
i just want to know if it is the metal chassis which is causing this problem
Good thinking!
Desire S propped up on two stacks of books so that nothing touches the alu parts: all bars. (It did drop one bar from time to time, but that's just normal fluctuations, whereas putting it down on a desk or something reliably takes it down a notch.)

Why? We arent't their QA department and I've no hopes of getting more than ... err ... yes, "You're holding it wrong." in soothing customer rep speak. Raising awareness of the issue is the best one can do, IMHO - once the tech mainstream press picks this up there's at least a chance of a fix. (That is, if one is actually possible, it might be a concession to the design.)

just got phone and wifi definitely drops when held landscape
So, I've been afflicted with the death grip issue at home something fierce. If I hold the phone in landscape mode as if I were to type with my thumbs, the wifi cuts out. It doesn't seem to matter how close I am to the wifi router or if I turn on Wi-Fi best performance. At home, the network is configured to use 802.11g for compatibility with some older devices.
At work, I run an 802.11n network (I'm the IT Director). While I've got much better access points and better line of sight, I have similar sorts of distances. With 802.11n the death grip issue seems less significant. The network never drops out completely (I lose maybe a bar) although network *traffic* seems to stall to a degree. This is true even if I go into other rooms where I don't have great line of sight.
I'm still doing some surreptitious testing (since I have work to do, too) but I thought I'd ask the rest of you if you're having seriously issues with the death grip, what mode is your wifi in? 802.11g or 802.11n?
I really haven't had this problem, when I hold it in landscape it goes down 1 bar but comes right back,I'm starting to think its device related ,just like the HD2 some of them had wi-fi issues and it was just the hardware couldn't do nothing about it but exchange the device
I used to have this issue until I changed the wifi performance to maximum and out a gel skin case on. Now mine doesn't even drop a bar from 2 rooms away.

Thank you
I would notice the signal go down when I held it in landscape but it never dropped completely but last night I got the real effect of it. I was streaming a movie from my computer and viewing it on my sensation using splash top (only about 15-20 feet away from the roiter) Everytime I held the sensation and touched the "death grip" spot my video would stutter.. Tried setting the wifi to max performance and I have the tmo gel case on.
I guess one difference between this and the Iphone antenna-gate is that if HTC does consider it a problem and does fix it, they only have to replace the back cover and not the whole phone
I heard someone said foil on the outside helps out the issue, but it looks really ugly. Wonder if we can come up with a fix that can be done on the inside of the cover. Maybe attach more wiring to the connections or something..
Wonder if those cheap cell phone singal booster on the inside cover would help out at all.. hey if foil did then maybe one of the will shrugs
I just have to say I don't think this "death grip" is a hardware issue .... I think it is a software issue. I had a g2 and flashed cyanogen ... Worst WiFi reception ever. Went for a more stock based Rom and bingo! Also I noticed if you turn off mobile networks from the task bar and turn on WiFi, you will have superb WiFi...
On the sensation of course. Lol

Trying to Figure out the Wifi-Death Grip Issue
Something Odd happened to me, i wanted to share with the rest of the comments here because i have not been impressed with my Sensation's performance so far. I have had the normal low volume and the erratic sense speeds along with what Phil showed when trying to use the carousel, but nothing was more annoying as with the wifi issue. I got it five feet from my router and i have two routers and one is open and one has PS2K. I tried it with and without the cover and behold i lost my signal when i held it in landscape or put it lying flat. I decided i needed to go to a T-mobile and complain about it, but while i was waiting to be attended, i went ahead and started playing with the sensation they had on display. To my surprise i could not duplicate the issue at all, I checked their version and went to the advanced setting under wifi and it was no put on maximum performance. I pulled out mine and as you could imagine, i could not duplicate the issue anymore. I was puzzled because although i lost some bars, it remained connected and i did not lose the signal completely or as easily when i was at home. I decided not to look like a fool and when across the street to a Best-Buy, and logged onto their open network and had no issue again i tried to put the death grip on it, put it in landscape or lay it flat on it's back and although i was looking some bars, i could not duplicate what was going on at my house. I went back home and reset my routers and the issue is still there. So from what i can tell, i think we may need to find out if this issue is with some routers only or with the encryption used.
FYI: I have a N1, IPad2, HD2, MY3G and don't have any wifi or death grip issues with any one of them so i am seriously leaning to a software issue.
Whatever, the issue i can see Why Phil and a lot others do not see this issue and i can understand why a lot of us are experiencing the issue. Hope something is found out soon.
Routers i use:
DLink (DIR 601) Open network
Ambit WPA2-PSK
(i have tried changing channels and updating firmware on both routers)
a video. Im not calling yall liars, but ive had 3, and all have the issue so I just dont see how others dont. Unless its the routers, and yours is way better than mine cause mines junk, but never had issues on other phones.
Anyways, please post a video showing in another room from your router, covering the top landscape style and take a video showing the bars. I dont care if they drop some, Those that say it dont vanish can I please see a video. I JUST DONT GET IT.
Thanks, p.s. I got my 4th sensation on the Way. I want this phone but dont want the wifi issue cause i use wifi 90%of the time.

Don't have another video camera, so you'll just have to trust me, or trust the videos that are posted on YouTube that show it working. I'm in another room, landscape, hands wrapped around the phone every which way, the wifi connection never drops. I don't have a case on the phone. Using Wifi Analyzer I do get about a 20-25dB drop in signal, but it's still plenty strong enough to stay connected and not drop data.
It's more likely something about differences in routers than the phone. Maybe signal strength, or g versus n, or the specific channels being used. Not saying there are no bad phones, but if you try 4 phones and they all do it then it's probably related to something about the router.
I've not got a video but I don't hold my phone when using it in landscape (I rarely use landscape at all tbh). I put it on my lap so don't have the issue
please please post a video someone. This is my only issue. If its my router and I need a N ill buy one, but I need a video of someone going to the router, then watching them walk to the end of the house in the room and do it. If it does not kill your wifi I will be sold and figure out why mine is..
Do you have a N router?
Is it just G?
This is serious and Ive only seen videos of them effected and experienced the same.
Ok so I took my case off and had to wrap my hand completely over the top end of the phone to show a difference, but it did drop two bars ,now since ill never hold my phone in that manner this will never be a problem for me , so I would say that the case makes a diff and its definately there , I really don't like holding it in landscape mode ever , i rarely do
For ref, I have a G router (a rebranded Thomson)

Can you test in landscape? since you dont go in landscape? or did you already and have no issue?
please post a video. If yours is fine there are good ones and ill find it. If not im trading back for my g2x today because that
so far Im getting. I have no wifi issue cause I never cover it?
well if you do hold your phone in landscape and have no issues, then please post a video. In portrait im golden, but when I landscape it completely depletes.
Here's a video that shows signal drop but no disconnect when the wifi signal is strong.
http://www.youtube.com/watch?v=j64GKuuczoE
This is just what mine looks like. Drop in signal, no disconnect.
Notice the other low signal wifi's in this vid do drop away. The same guy also posted a video showing a total drop in connection if the wifi signal is relatively low at it's peak. So, at least part of the reported problems could be due to a relatively low max signal.
If you don't have Wifi Analyzer get it and post a vid so we can see what's going on.
I will make you a video the second I get off work at 4pm. I will show the router on video, then walk up stairs, hold the phone in landscape and show that none of my bars disappear. Do I get anything in return or do I just prove I'm not a liar? I am really not trying to knock anyone here but I find it odd that we can all buy top of the line phones but still use shifty routers. A goog router will make your life a lot better for a fraction of the cost for your phone. I suggest everyone get into the year 2011 and atleast by a N router, if not a dual band N router.

Ok that. WEll, hes next to the router, so thats why the wifi dont die, but I garuntee that if he goes in another room it will die. WE need to see where his router is before we judge if his connection never drops. I bet hes in the same room.
WIfi analyzer vs my vibrant is amazing. Vibrant perfect barely loses db. Now the sensation loses 20 no problem. So in a room with wifi it will be connected, but in a room with less signal, you will cover the signal and kill it. It shouldnt be like that.

You've identified why people are reporting different experiences, which is exactly what I said. If the signal is strong then the connection won't drop. If it's weak enough at max then it will drop.
The loss of about 20-25dB by holding the phone certain ways is known, and isn't likely to vary much be getting your 4th or 5th Sensation. You could try holding it differently, or maybe some types of cases (with or without PT ) may help. Or you can get a router with a stronger signal.
Whether or when HTC will do anything to fix or improve the issue remains to be seen.

Please, I would love that... Cause if so I just need a stronget router even though my other phones work fine sitting on them..
I live in a small apartment and I have a good router (bought it like a month ago) even when I'm standing directly in front of it, the signal will drop (I watch the meter in wifi analyzer drop) If I'm in another room it drops even more. I have my phone set for max wifi performance too. One night I really noticed it while streaming a video from my computer via splashtop. Every time I held it a certain way the video would actually stutter. I wonder if the people experiencing it have some kind of grounding problem with the phone. It's not a huge issue for me because it never fully drops and when I hold it in landscape mode I just make sure My hand doesnt cover all three anntena holes on the back. It seems when your hand is in contact and covers all 3 that it drops. I should be getting another sensation on friday. I hope 1. the wifi drop isnt as bad 2. That I get the better sharp screen

I have one coming soon as well. Ordered today. Will see how it goes. I just don't think I should have to get a new router when my others phones work great.. I'd say grounding causeof if I put tp between my phone and case I can't get it to drop... Move the 2 layers of pt and it goes away.
Sounds like you should just ditch the Sensation; some feedback from my experience; I have the Rubberized case on mine and at work with the case I get about 1-2 bars of WIFI; without I get almost full.
Turning it landscape also kills the connection with case and drops to 1 bar without case so thats pretty ****ty although I don't use my phone landscape or really play games on it but for people who do I could imagine that sucking pretty hard.
Was gonna do a vid but I don't think it's really necessary. If you have a strong signal (ie sitting next to the router) your likely not going to notice anything at all; if your on a medium signal it's likely you will lose bars or total connection.
Not really sure what video proof is going to do for you however as it really doesn't matter what others are experiencing in this case outside of their verbal explanation.
I have to agree, this issue is annoying. In my house I have 2 MT4G's a Thunderbolt and the Sensation. None of them drop wifi signal like the sensation does.. I don't use a case and sitting 3 feet from the router I'm ok, even turning around facing away from the router at 3 feet I'm ok but it does drop a couple of bars. In other rooms I have full bars but if I cover or hold in landscape as has been shown I loose all or down to 1 bar and most of the time it will disconnect.
Not sure what type of router mine is as it is from AT&T UVERSE.
Here is my video 3 rooms away from my router I drop a little but no disconnect.

Hi all, please welcome me whom had bought the Optimus 3d just 2 days ago. I love this phone. Please do let me welcome you all to talk about a flaw, which I've found out right away with the new phone since 2 days ago! I've been with some others Android phones, so, I should say I've had good experience with Androids.
I realized that Optimus 3D has some kinda hardware Radio receiver flaw (I really don't know what should I really call it) similar to the famous iPhone 4 dilemma in the beginning. I found out that the "Radio receiver" is located somewhere at the bottom of the phone, where our hands most often holding the phone with. The hand will block out the signals and the signal bar will be reduced by a lot as much as to zero (if the signal strength itself is not strong in the 1st place!) Try find this yourself, have some experience by holding the phone at the bottom and let go and holding the phone and again let go, keep trying this you should see the signal strength that will drop and rise and drop and rise again. Or is this only my phone? But I've never experience this phenomenal with other Android phones!
Also, I don't know this has the directly link to the downloading issue or whenever browsing nets, the network data will drop very very often. I hardly got successful downloads from the market without few retries. Thank god at least at the moment I can temporarily fix it by turning off and on again with the data enabling shortcut in the pull down menu.
Please help me here and advice! Very much appreciated!
Since the famous iPhone 4 drama for a lot of phones these stories pop up once in a while. I know lots of people furiously believed the Samsung Galaxy S had the exact same problem but after a week or so nobody ever talked about it anymore.
I myself have absolutely no problem whatsoever with the signal, not even when I completely cover the entire phone with my hands leaving just a small spot to read the signal it never drops, not by one bar. I've never had a single download dropped with either 3G or wifi and I've downloaded my share of stuff from the market and other places.
I've tested this with my T-Mobile simcard (which has pretty horrible coverage here) and with my Vodafone simcard (which has great reception) and with both simcards the signal strength stays exactly the same according to the bars. Even when I go to the settings the dBm and asu values stay exactly the same, no matter how long and how bad I cover the phone.
So far you're the first and only person I've read about having these issues so I think it just could be an isolated incident, although that would be bad for you as that would mean you could have a defective phone
This problem is not something new and is not related with O3D.
All the phones have the same issue.
It is normal that if put your hand on the antenna the reception will drop.
The radio waves just work like this.
However the atenuation from your hand is most accentuated on higher frequencies like 2100Mhz.
On every phone even on the oldest phone with external antenna you will meet this phenomenon.
The difference between 4 bars and 1 bar is only around 10dBm which really isnt that massive a drop at all. Now that you've pointed this out i do see that the signal strength varies a little depending on how you hold the phone but its not enough to panic about i don't think. The iphone 4 problem was significantly greater in that the iss was that a user's hand would electeically short the mobile network antenna to the bluetooth and wifi antenna causing a total loss of signal. While 10dBm or so is a definite dip in signal strength, it's an acceptable level of attenuation and i dont see it causing any real world day to day network problems that you wouldn't experience with any other high end smartphone.
My workplace is in a giant tin hut of an industrial unit (read: faraday cage) and today while i had this phone there for the first time i saw no noticeable network coverage problems. The behaviour was as far as i can tell exactly tue same as my motorola milestone from which i upgraded.

As stated all phones can lose a bit of the reception when it's in your hand depending on how you hold it, the reason Iphone4 was such a big deal was that it was extremly sensitive when it came to left-handed people and they had a real problem with their antenna being totally blocked when holding the phone normally when speaking in it.
Later on media and uninformed people started fueling the flames as soon as they saw a bar drop when picking up the phone, radio waves are not magical rays or tachyons that can move though matter without interacting with it.
thanks for all the replies. Believe me or not, this is the 1st phone I realize this issue and it is so obvious, the bad news is, it is really bad for me that the antenna is located at the bottom, probably most others phones I've owned were at the top as a result i didn't got any problem before.
And another issue, I'm pretty stucked with the shipped rom now, really hope to see custom roms soon. I'm at the moment totally freak out with the inconsistent of data and the wifi, it keeps failing me, this really freak me off, what the hell is happening to me with this phone! I've never ever got any dropped data or wifi connections before. Arggghhhh!!!!!!!!!!!
I have no signal drop out no matter what hand positioning i use..
I'm in a very poor reception area. I do notice hand over phone a drop from 1 bar to none. Still not a red cross to indicate no signal but a drop of 1 bar all the same.
Just tested it.
Signal drops from 4 bars to 3 (1-2 in awkward positions) when hand-held. Not an real-life-usage impact though...
Thanks for all the test replies to support my findings. OK, now, I've realized that the hand holding issue has no direct impact to data drops. And the data drop is entirely due to the time issue which it does not lock down the data connection when swithcing data modes. And at the moment it can beasily over come to turn off with the data button in the pull down menu. I'm not sure though when in the situation when the signal strenght was so low, by holding with hands will give an direct effect of data drop or not. Will observe that
I have a HTC one s and it is experiencing wifi problems. I know the one x has had some of the same issues, but the problem with my one s is that whenever i hold the device from the top, the wifi drops suddenly and it than cuts off. When i remove my hand about, 5 seconds later the wifi shoots up to 4-5 bars.
return it and get a new one
That's where the antenna is!! Your SIM cover has the antenna built in to it.

Moving to Q&A
Try to remove and reseat SIM card cover, if its still too bad have the phone replaced. A friend of mine had his One S replaced after we compared Wifi signal with Wifi analyzer and his was ~20 dBm worse than mine at same locations. New one is fine. Didn't know about the wifi antenna on sim card cover back then though, might have helped since it seems it has for some users here.
I have almost the same problems with WiFi antenna although it's not as worse as others are saying. I can confirm though that when you put your hand next to the SIM cover the WiFi signal drops 1-2 even 4 lines at some times. However I don't think it's a manufacturing defect for some phones but I think it's a general problem with all the models. I am saying this because I had the exact same problem with all my HTC devices (Diamond, Desire and One S). So I think it's a poor WiFi project and maybe cheap raw materials rather than a poor WiFi in some phones. In a way it's normal that this happens because your hand will screen the antenna. Try to do this with all antennas out there and you will see that your hand (your body) will influence the signal in all devices). So if they couldn't overcome this problem they had to put the antenna in the place where you will cover it most rare, and this place is on top of the phone. I don't like it either but that's the way it is.

just noticed the same this morning, though only happens when i try to wrap the upper part of the device with my hand. i never hold the phone in that position so it does not happen.....
Actually when you are browsing the internet, view pics one-by-one, view movies - usually you are holding the phone in the landscape mode so most people will rotate the phone counter-clockwise until it reaches landscape mode and will hold it with the left hand exactly from the upper part (if the phone is rotated clockwise then the supporting hand will accidentaly touch the lower 3 buttons so not too many people will rotate it clockwise) and with the right hand they will browse. So in these situations, which come very often, we will loose (almost all) signal. If these will not bother you/me/all of us, for sure it will bother all of us when browsing internet. I really don't know if a fix can be made for this issue. Even if I would change the SIM cover (so change the WiFi antenna), the replacement will be built exactly the same so the problems will persist. I am curios to see if SGS3 has the same problem or not. I really think it's a question of antenna position so it's a crappy board design of the phone. It shouldn't happen at a 500+ euro device.
I have the same wifi issues on the One S. There is a firmware upgrade available OTA, it may fix it. I will see.
Any chance this is fixable or not device-wide? It's somewhat of an annoying problem when holding in landscape. I'm assuming this is no more than a design "flaw"
I'm having the same issue. When holding the phone in landscape mode, the wifi signal drops to one bar.
I noticed that when I'm closer to the router, like within a 3 meters range there is no signal dropping.
It's very annoying...
Could it be fixed by improving the contact between the antenna and the back-cover?
Sent an email to htc support about it, this is their response:
The location that you describe, on the side with the Power button near the camera lens, is where the HTC One's antenna is located. Covering this location will provide less-than-optimal results with regard to cellular and WiFi signal. You may want to try holding the device slightly to the side of this location, more towards the center of the device.

I seem to recall a certain fruit phone with a similar problem and it was kinda a big deal lol. I'll get over it, but fokkkkkk

Did you guys try remove and reseat SIM cover? Might help a bit even though its natural with some signal loss when holding it that way. If your phone has significantly worse signal when laying on a table or whatever compared to another phone then try to get it exchanged.

Edit: Love how your quote from HTC disappeared when I quoted you
traffic stops after few minutes
Hey,
my signal is ok, but after few minutes of working the internet connection just will not go through anymore. I have tried installing 4.04 but no change. AP is still connected, full signal, but not even google comes on. Restarting wifi helps for another few minutes. Doesn´t have to do anything with sleepmode, that I am sure of - it happens even during download from Play Store i.e.. Wifi best performance ON, Keep Wifi on during sleep Always.
Any idea on what that might be? - the old HD2 (android 2.3.) works like a charm on my home network
Getting desperate , otherwise such a nice phone.
