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.

How do you set the WiFi to maximum?
Thanks in advance

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)
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.
Phone looks great, but i figure with the antenna's on the back of hte phone like that there's bound to be some "death grip" issues.
I see one thread on this forum about this issue, but since the community has grown since then i figured i'll ask again.
Compared to my previous phone (Galaxy S), the reception is better in all regards except for wifi. Although wifi is comparable, covering the antenna with your hand causes an instant and noticeable degradation in signal strength. If you're not close to your router, this signal loss is enough to drop the connection.

My girlfriend had just got her sensation yesterday and usually I'm the one to get all the new gadgets I've had the mytouch 4g, g2 4g the evo 4g and now shift and we live in a apartment and all the tmobile phone I've ever had sucked but that phone has the best connection I've ever seen or used in my house for some reason she's getting way faster speeds and of course she wouldn't let me flash anything to it like new radios or anything lol oh yea and she's also using the phone without a case

This. This describes the reception perfectly.

All the reception on this phone is amazing for me. Way better than my G2 and Nexus S! Especially data and Wi-Fi reception. I never lose a 3G/4G connection and at work where I don't have signal I really on Wi-Fi calling and it works perfectly for me (My G2 used to always cut off and drop calls).
GSM reception is excellent. Better than HTC of the past. The G2/MT4G have atrocious reception especially on 4G. GSM reception is better than my Galaxy S, 3G/4G seems to trade off with the Galaxy S picking up on a weak HSPA signal more often.
WiFi reception is horrible in landscape. Fine in portrait with no hands over the top half.

I have to concur with my peers. GSM is great here in southern California, but even as I type this...I'm in portrait because landscape will cause my WiFi to drop. This only happens when I'm not next to my router...so pretty much dies all the time. I already went through 3 phones all with the same death grip, which HTC is just looking into the cause. That's what one rep told me from their USA tech support. Hope this helps

Everything has been fine for me. I haven't noticed any death grip issues with WiFi in portrait or landscape.
Cover the top of the phone and I lose WiFi, cover the bottom and I lose 2/3/4g. Thus when I hold the phone sideways I lose almost all signal.

Thus far I have not had any deathgrip issues like most others complain about however compares to the BlackBerry I came from the radios receive much less signal side by side. Don't get me wrong I love the phone and features but signal is poor in my opinion and with my job I am around cell sites all day so I know what I should expect
Mine's just really bad when it comes to receptions -___- I get no wifi at all no matter how close I am to my router, once I cover it when on landscape mode. && how I see these people having reception when I'm on Bart(underground) I use to have full bars with my cliq down at bart, but with my sensation I don't get any service at all down there.

Blackberry uses a different scale to determine the amount of bar, the -dBm reading goes all the way down to -120. Android only goes down to -113 even though the actual signal can be lower than that, to -121dBm. A Galaxy S with Touchwiz can show you the real -dBm reading after -113 on Android (no bars) with it's field test mode.
yeah fortunately i do not rely on my phone for field testing we use test sets working on the antennas and lines. and we work with a remote test center that runs NRPM testing for diversity issues. (we work primarily AT&T UMTS technology work in the midwest)
wifi issue is the worst, drops in and out constantly from wifi to mobile network. dont ever use a case in your house you will lose wifi 90% of the time. dont listen to these fan boys

I was having the same issue for a while, but it seems to have worked itself out.
I've not had a problem with Bluetooth or WiFi, but the 2g and 3g reception is erratic wherever I go. This is on Vodafone UK.
Have tried my sim in my old HD2 and I get a much more stable signal.
just went to Bell to talk about the HTC Sensation. I asked if the lady heard anything about reception issues with the Sensation because of its design.
She said she hasn't heard of anything but she likes the new galaxy s 2 because, and i quote: "the pixels are faster even though they're the same speed"
I said "oh yea? " and left.
the responses in this thread seem to be 50/50. i guess ill need to hold one myself to test
anyone want to have input on this vs the sgs2?
I just called HTC and had them send me out a new battery door. I was having problems with the signals. Have any of you had these same problems? If so have Yall got a replacement from HTC and did it fix the issue?

nope, haven't had any reception/signal issues at all.
I believe the death-grip affects your wi-fi signal. When I move my phone to landscape mode and hold it as indicated in some videos, momentarily a bar goes down in my wifi signal but nothing like an interuption. It doesn't drop (and reconnect) wifi either.
It seems to be a hit or a miss with these phones

This is why I'd really like it if someone who replaces their battery cover could post before and after wifi signal strength from the same location. It is possible that there has been a redesigned battery cover with a better antenna placement.
I only lost 1 signal bar so i think its normal - like other phones
I am currently having a HUGE problem with death grip. So bad that it drops my WiFi calling when im texting in landscape even from about 15 feet from my router. I am going to call HTC tomorrow and request a new back cover just because its a free step I can take to try and fix it.
seems like HTC have a problem with this model
i have to wait 7 days for my Sensation to come from service
then i will see what is the next step... media, solicitor .... we will see
signal its rubish anyway

ok... so after reading your post I decided to test it out. My router is on the 2nd floor in the study. I used landscape mode to send a couple of emails and texts from the first floor and outside my home. The signal dropped a couple of bars each time and recovered. Didn't drop the wifi signal for sure.
I think it is still a problem and HTC needs to get a fix out. Don't know if it will be a f/w or h/w but it needs to be out. I guess if everyone having this issue raises enough hell, HTC may act sooner.
The 4g phones seem to have a different placement of the wifi antenna and does not contain a death grip like problem due to this reposition.
You can higher the wifi signal (battery usage) in the wifi advanced settings.
Doesn´t help anyway?
All sensations will do this. Rooting the phone and installing custom ROM will fix the issue. Before if i placed my hand over the top of the phone, wifi would drop, sometimes even lose signal entirely. Now after root and ROM, it doesn't even drop one bit.
I was about to return my phone due to this issue, i am glad I waited a bit.

My phone is rooted (s-off) with all bloatware removed. Its still on stock ROM though.
Since we have S-OFF now, the custom ROM's for sensation have started to flow. Just waiting on those ROM's to be stable before deciding on which one to use.
BTW which ROM are you using!!!
Changing the back cover will make no difference. I got a replacement and saw no difference at all.
When I would go into landscape I would lose 1-2 wifi bars, but after I flashed Android Revolution 1.1.6 and kept the stock radio I started only losing 1 bar if any at all.

I haven't experienced this at all. compared to my buddies iphone 4 where there is a serious death grip problem any drop in signal on my sensation is moot.

I've heard that it does, but I'm still waiting on mine to arrive. We have FAR FAR lower signal strength with this phone than with our other phones (motorola cliq / mytouch 4g's)
I just checked and I'm on zero bars right now. I usually have 4 bars right here with my other phone. It's rediculous. Holding the phone reduces my signal strength by ~40-50%. It can completely lose signal, right under a tower (in visual range) if you hold your hand flat against the back.

For many people, this is not the case. I know there are different revisions for the back cover. I think it is due to that.

Did your wifi situation improve after u got the new cover? my device sucks.. it drops all the way down to zero.. thinking of getting the g2x instead
Signal is good when phone is turned to 2G only, so this appears to be a firmw-/software issue rather than a battery-cover issue.
I had the same problem when i first recieved the devie but as you say custom rom sorted that
Getting weak Wifi-signal on a friends One S, attached are screenshots from Wifi Analyzer comparing reception with ye olde Desire running Sandvolds ICS. The One S consistently is quite a bit worse off by ~20 dBm and sees far fewer networks at any given location. Another old Desire running stock gingerbread also outperforms the One S.
Thoughts anyone who upgraded to the One S? How is your Wifi compared to old phone?
My One S gets 5-10 dBm worse than my Xperia X10 on CM7

Comparing my old Desire (AMOLED, CM7) to my One S the signal strengths are about the same.
But whereas they are stable on the One S they oscillate on the Desire, and the One S is more sensitive, means it shows more different signals in shorter time. The Desire doesn't show them at all or at least less signals, maybe due to the oscillation.
Oh good gosh.
The sensation had the grip of death.
The amaze has a WiFi problem now so does the HTC One S.
The hell HTC? Fix the WiFi issue.
Had my one s for a day now. Been at the same locations around my home as my old desire. It shows far better WiFi reception than the desire both when it was running runnymede and leedroid gb with different kernels.
No WiFi trouble at all.
My sensation was appalling for signal (wifi, 2g/3g) i complained to my provider and thats why i now have the One S.
I must admit, Its not perfect but its a whole lot better. Only had it working a few days so cant be 100% sure, But im getting signals is places i couldnt with the Sensation..
Im happy i can use it as a phone, I would have like it to be alot better but thats life i guess.
It works so i cant complain.
No issues for me... WiFi reception is just as good as the old Desire had. Didn't test it with any apps, but I can get reception everywhere in the house and even outside the front door, which I think the Desire couldn't.
Good thing its not a very common problem so far, maybe HTC spilled some of the micro arc oxidation stuff on the antennas of this One S then It has problems connecting and speeds are bad where multiple other devices work fine. Please keep the anecdotes coming!

No wifi issues here. At least as much signal as my old Desire
i can't complain about my wifi. Even though i get 5-10 dBm worse signal compared to my Xperia X10 i can still connect everywhere inside of the house as well as on the street ~15 meters away from my house. I also get much better speeds with my One S. We have a 30/30 mb/s connection but my Xperia could only use 10-15. The One S on the other hand gets 30/30 every time
The phone in first post is on its way to HTC to be fixed or replaced. Attached screenshots of firmware and radio versions in case someone needs it
My One S wifi signal is around 10 to 12 dBm weaker than my Motorola Defy+ but it still works very well so no issue. Mobile data signal is a good 16dBm and more, weaker (as mentioned elsewhere on this forum) than the Defy+ which is somewhat of a problem. Contacted HTC but awaiting a response.
I have weaker WiFi only when the router is in distance. My incredible s could get one or two bars so does one s, but it can not connect to anything.
When near the router, they all work very well mo problem.
From WiFi analyser the signal strength are similar.

When in my room, i always loose wifi connection when a finger is over the thing you can take off to insert sim. i noticed it because i always loose wifi connection when holding it in landscape
can only compare to iphone 3G which was a little better in keeping connection and had no specific grip of death.
I came here to ask this same question. I don't get a full wifi signal when I'm literally right next to my router. You can forget about it just 20 feet down the hall. really poor. Much worse than on my G2. And I only get edge speeds at my house. Really, I get edge speeds in my den where the tv is but i get 4g in other parts of the house.
This is soooooooo upsetting!!!! Am having wifi issues too. My phone randomly jumps on and off my Wifi while I'm in my room. Mean time my laptop's @ 90% to 100% signal.
I am actually getting much better wifi (using rooted stock) than I did with my HTC glacier running CM7.

Make sure that your SIM access cover is snapped in place.
It happened to me with the WiFi signal - The phone was losing signal, and had low signal 1 foot away from the router.
I 'pinched' the top-right corner of the access cover (thumb on the glass, index finger on the back cover) - I heard a 'click' and suddenly my WiFi was at full strength. I believe that the WiFi antenna is not connected unless it snaps together.
I haven't had any WiFi issues other than low signal at moderate distances from the access point. Once I turned on Best WiFi Performance in the phone's settings though, even that minor issue went away. Couldn't be happier with the WiFi performance, especially after all the WiFi issues the NS4G had.
Check to see that best wifi performance is checked in advanced settings. Not knowing any better, I turned this ON when I first got my phone. A few days later I decided to turn it off to see if it helped battery life. With it off, I got the constant signal drop that someone else mentioned. My son got a One S at the same time I did. He was complaining about occasional reboots. There was a thread on the T-Mobile support site that pointed to a wifi issue. I had him turn best wifi performance ON, and his reboots went away.
