The HTC Sensation Death Grip - GSMArena - HTC Sensation

Is this the reason why people seem to be suffering with poor signal? Not good news
HTC Sensation suffers from death grip, iPhone 4 caught snickering
But then again nobody I know carries the phone around flat in the palm of their hand, so probably just another overreaction from the HTC Haters

just saw this at gsmarena too... can anyone do a re-test if this is true? i want to get an htc phone but these things really bother me.. please confirm guys

Just about every phone I've ever had had a death grip issue, including the Vibrant and the MT4G. Since the phones had to be held in a particularly unorthodox manner to experience this, it was a non-issue.

I agree, if you look at the video of the Bluetooth music, when holding the phone in the normal position it works perfectly.

Yep. Just people overreacting and trying to make news.

I'd love to see a video of a phone that can't be made to suffer some signal loss by holding it in a certain way.
The key question is does it suffer significant loss by holding it in a normal manner. More practically do you get wifi, call or GPS drops when using the phone normally. Show me that video and I'll care.

I don't see this as an issue since how often or why do would you need to put a death grip on your phone

Tried to replicate these issues, cannot. The initial signals must be too weak to start with, so disappear completely - or, the whole thing is a fake.....?
Bluetooth is shorter range anyway, isn't that the point, it's meant to be low power.
My Sensation wifi reception isn't the greatest but I have no issue with it, however I hold the phone
Tbh I am surprised at a site like gsmarena posting 'sensational' claims..... without knowing the whole story.

In 2 words: bull ****.
Really, I can't understand why people are searching those issues which are not issues at all O-o
I mean, every phone does suffer from signal drops and all that kind of things, but well.. it really depends in which position.
If you look in the video, the phone works perfectly when holding it normally.. just when you hold it like I dont know what ( who will hold it like this?) the signal drops.
So I think there is nothing to worry about..

I think that this is a valid issue since when you browse the internet and hold the phone horizontally for landscape viewing then this might cause the wifi signal to drop. I have read this issue also on the HTC Desire S. I went to the store to try and its really true that when you hold it horizontally, the wifi signal would drop. So i guess that this is also happening on the HTC Sensation.

Isn't GSM arenas phone missing a contact?
slash gears sensation has an extra contact thus I'm assuming equals better reception.

It's because SlashGear has the US version while GSMArena has the UK one.

Yeah, apparently the 4G model has an extra contact point.

The T-Mobile version needs another contact because of 1700 MHz band (not sure, I'm just guessing)

if the sensation is anything like the HD2, the GSM Antenna is in the lower part. On top are the Wifi+BT (same Antenna) and the GPS. Total of three antennas.
Also, the HD2 had the same arrangment were the back cover (plastic)had all the antennas & they were connected by similar conacts. The difference simply is that with the sensation the cover comes out when removing the battery while the HD2 had the plastic back fixed. So if there is a problem with this design we should have noticed it in the HD2 first.
Another thing, the BT streaming sample done, as per swedish source was done at 6m distance. which kinda long for purpose of bluetooth!!

Does that mean the Sensation's Wifi, Bluetooth, GPS, Radios won't work if the back cover is removed? That would be too bad coz my HD2 works fine even if the battery is exposed..

Today I found out that I am also suffering with my sensation.
It is absolutely no bull****.
This is my third HTC, I have next to my Sensation a HD2.
With my HD2 the deathgrip was only a problem when i cover the hole with my top hand, i never normaly do that so it wasn't a problem.
But with my sensation its a much bigger problem.
If i hold him in my right hand, there is no problem.
if i hold him in my left hand and touch with my right finger then you see that he is losing signal.
if i hold him in landscape mode then almost all my wifi signal is gone.
If i hold him in my right hand and tick with my right finger on the top of the sensation, the wifi wignal drops down.
And the biggest problem is that he loses the wifi signal and then he is searching again for wifi.
I have never tested Bluetooth, and i have 3 antenna points in the cover.
maybe i will make a video later.
and sorry for my bad english, google translate Helps me

when i remove the back cover all my signal is gone, he says: No service!
because of the bad range.

Hard to belive ppl are not thinking this is a problem.
That Position is MUCH more common then the Iphone 4 death grip... Also the issue is much more prominent on the Sensation then on the Iphone 4.
EDIT: I can NOT belive how accepting ppl are of the HTC sensations faults. It REALLY saddens me.
PPl.. there is no need to Defend HTC with your life. They are one Company. We should be choosing best company not being fan boys. Every1 should be able to recognize the problems phone have.

Anyone try the Eten Glofiish X500

Has anyone tried the OS on the Glofiish X500.
http://msmobiles.com/news.php/5793.html
Actually I got this one, and have a few other qteks/ipaqs laying around too.
The screen used is the best screen I've seen in about 7 years of pda using.
Contrast is way higher and sharp, colours are rich.
The display has some colourbleeding though, if you switch from a dark screen to a light screen like the blue today screen you see a vague impression of some of the black parts of the previous screen.
I don't find it annoying at all, I hardly noticed it after a few days using.
It has an internal radio, but you got to use the headset in order to listen to it, the antenna is build into is.
This antenna isn't real sensitive, and the radio signal doesn't get pick up to well except if you use like 80% of it's length.
The device itself has realy been taken care of, aluminium details, rubber back, it a has a touch of quality to it.
You get a leather case with it which is brilliant, though I miss a beltclip on it.
You get many software on it, the best is the phone filter, which you let block certain phone numbers.
You get a battery bar too which is in the programm bar on top, at least they thought of it! But it lacks something like x-button, would have completed it.
Then you got image maker, which makes me think of paint from windows 3.11, no clue why it's there but oh well, did I say you can remove any of these single software pieces? what you don't use you can simply delete to free space So much for the extended roms of other phones of other brands.
Then there's a simple multimedia browser which let's you browse through directories and show pictures and sounds, not to bad either.
Plus there's some image wizard to add borders to pictures etc.
Then there's some mms software, which is pretty nice.
I already mentioned the call filter didn't I?
Then there are 4 profiles called "scenarios" software, it's nice but not real good, but at leat it let's you turn off the sound for a meeting.
Then there's some skype receivers switch which intergartes skype into the software, which is nice, and skype is installed too (which is 5mb and since I don't have a need for it I de-installed as first!)
Then there's some speed dial which is actually pretty nice, big buttons with name + number in it, actually use it a lot while driving.
Then there's some voice commander, though it's funny I never really used it.
The 2 mpx camera in it isn't to bad, one of the better I've seen in pocket pc's, but still it has a long way to go to be able to come close to nokia's (I'm jealous at the lenses they use in it! I really am)
The software for this camera is real good, nice big buttons for the functions and on teh case you got nice buttons to zoom, at exactly the right place.
Fron the back you can't tell if it's a pda or a camera actually!
All by all E-ten has by far the best quality I've ever seen in a pda, and the price is quite right too!
Here in the Netherlands it's only 30 euro more expensive than a htc 3300 which has about the same specs.
I wouldn't have a hard choise if I had ever to choose again between brands, E-ten is THE brand of choise for me.
Just to bad there's no E-ten x50 subforum here, really miss it.
If people want I could try to see if I can get into the extended rom and get all of these nice apps for you people.
Hi. iruja, I would like to try the eten call filtering and also the location sms sounds interesting.
How stable is the eten?
I was told the GPS is horribly slow to get a fix, can you confirm this?
I'll see if I can get into the extended rom later on.
In fact the e-ten is really stable, much more stable and more responsive than my overclocked wizard.
The gps gets turned on as soon as you start tomtom or igo, and I get a fix within 5 sec(!), being outside.
Inside the home it takes some longer, and the signal will drop from time to time to under 3 sattelites, but why would you want to navigate inside your own house anyway? (granted, maybe if you own a caste )
The gps is really sensitive and has no lag, my qtek with an external sirf III gps had a lag of about 30 meters, on my screen I would be before the turn while I was actually passed it, no such thing with the x500, could be because of the faster cpu I don't know, but both gps use the same chipset.
The only place I could think of you would get a bad signal would be around flats and high buildings, but even within Rotterdam I had no problems navigating.
In short, the gps works flawlessly for me, but can't speak for everyone.
[Edit]
The wizard solutions for unlocking the extended rom won't work on the x500, I'll try other stuff later today, maybe someone has a idea?
[/Edit]
I switched to Tytn after my X500 was repaired two times due to a faulty GPS chip. The motherboard was
replaced both times. It is a nice PDA, but has reliability and ergonomics issues. I' d suggest that you wait for X800 or X500+ , as they may be better thought out VGA devices.
I have also read that Eten will definitely be upgrading their phones to WM6 and will be providing new rom to existing users. Ya it would be great if their was a Eten subforum.

the x500 will be re-released as the x500+ soon and although identical in size it will have a VGA screen as well as WM6.
Hi iruja, just downloaded the ext.rom thank you.
I am trying some of the cabs now on my orbit, so hopefully I won't have to reset it too many times.
So far I've tried:
locationSMS, this seamed to work but when I got a GPS fix and hit send it hung for about 2 minutes and then notified me that my message could not be sent. So maybe I need a fix for that.
ScreenKB which I thought might be call screening, but that refused to install at all.
GPS Viewer which looks good and works well on the orbit.
Screen keyboard is a onscreen keyboard 2/3rd the size of the screen which allows you to quickly tap and send sms, quite nice.
Maybe some people can make an all device version of it? like o2 plus?
Have you tried message ease it looks really interesting. I will try it once I get my X500 in a week.
Well I'm just tapping with my fingers and I'm pretty fast with it, I like it better than the other thumb pads around I've seen/used so far.
Just bought one here's a pic.
Next check this will be my new device!! Like the specs, hope hardware issues wont hinder my ownership. I have wanted this device for a month, reading, rereading revues.. Hoping. Then I see pthomson's animated gif. Priceless, and here I sit speechless. Any one know the BEST price in USA?
I found
Item #: X500+
Price: $574.99
Any site better pm me plz
PS there is a forum @ eten for there device.
scarry post for me from yesterday
"Should add the memory leak problem...
Huge problem for me...
Philippe"
Any one else have memory leak issue? Just looking at the animated gif, that looks like a nice LOAD test device.
I have found a little memory loss but not bad at all. I purchased mine on ebay I have seen it sell for under 500.00.

The Samsung 4G Naked: Side by Side in the Nude with the Vibrant

Good Evening,
After taking the 4G apart several times I decided I would take pictures to highlight the few differences. Some noticeable differences:
1) antenna placement on the board, matching contact placement different on the back housing underside
2) the connector for the headset is different and the ribbon is labeled T959V (model # for the 4G)
3) less memory which can be seen thru the software
4) the GPS still sucks and does not work on this one
5) maybe I received a defective unit but there is an overheating issue. the 4G uses 200ma more than the vibrant but maybe the phone or the charger is defective as it keeps overheating and with time charging seems to be more of an issue/concern. software confirms this with error message.
Enjoy the pics.

Wow Samsung.. a new model and you STILL can't get the GPS right? This is absurd

Yes - confirmed - camera has the same plug connector. I swapped various parts back & forth to test things out (actually using them, took pictures, etc.) and the only things that are not compatible are the headset plug connector; I guess that is why it is the only part inside that has T959V labeled on the ribbon itself, and the back housing - the antenna contacts receptor(?) on the underside, since one of them was moved to the top of the board, which is also labeled T959V instead of i9000 as it is on the Vibrant.
My gps works great. Maybe its just your phone?

The modem is one of the black chips soldered onto the board. So no I don't think it would be that easy even if you have those robot precise soldering skills. I will upload a picture that shows the chips and identifies them on the Vibrant (same layout as the 4G but obviously the modem is different on the 4G. Then you have to consider that the extra 20% juice this phone consumes (1000ma on the 4G vs 800ma on the Vibrant) is to power the new modem. So even if you did have the soldering skills, then you might have a power problem.

Yes, it is a possibility. The phone keeps overheating as well when charging, it gets extremely hot. I think this may be a defective unit I received.
i got my 4g and so far no problems with battery or GPS... gps was the first thing i tried and it worked great. im guess some of these crappy phones are slipping through Quality Assurance on the assembly line...

You are totally right. You would think after the GPS mess & outrage with the Vibrant that they would be more careful this second time around. Apparently they did not listen or learn. It really makes me consider going for the LG Optimus 2X instead of the S2. I really want to get the S2 but these problems keep worrying me. It is like loving someone but they keep beating you up, do you get out of the relationship or keep hoping it gets better? Hmmm....
my gps works alright, sometimes it's a little wonky but nothing horribly concerning. i haven't gotten the overheating issue once although my battery is kind of sad.. i've rooted it and used setcpu to underclock when idle but still just short battery life.
i have noticed, however, that i have a green tint to my screen. noticed when taking photos that skin tones are off, then i email it to myself and check on other phones/computers and sure enough, it's just my 4g screen that seems to be tinted green a little. anyone else notice this or is it just me?

Hmm that sucks, if you are going to keep it, that is a problem I would not want to have, try get it exchanged. Thanks for letting us know about your problem.
Maybe someone has a solution and can offer some advice for the green tint?
This thread alone just convinced me that there is no way I would upgrade from the vibrant to this. What a let down. I considered getting it at first but thankfully realized they are just the same phone.
Moved to general as not android development
My friend and I both got 4Gs' at the same time. My gps fixed within 2 meters in my home, his running side by side took a long time to aquire. We rebooted his, gps took a long time to aquire but after 2 min, it did, but was within 9 meters of same location.

I wanna know...
I see the GPS is an issues. But I wanna know from yall that have the SGS 4G, is this the phone to buy right now on Tmobile or go a different route?
Im still rockin a Touch Pro 2. Contract about to end soon. I was lookin at the myTouch4G but the SGS 4G has better looking radios. Where the myTouch only has the 14.4 stuff.
What's yalls thought on it?
I have used both and they are both good phones. The decision for me was made by the screen on the GS4G, the Super AMOLED just looks so much better to me. The MT4G is a more solid feeling phone and it is plenty fast (processing wise). The GS4G is noticeably faster on the 4G network and I also get faster speeds while on WiFi, not sure why but I will take it! Coming from the TouchPro 2 you will be happy with either, I just prefer the GS4G.

Really bad call quality / speakerphone compared to my captivate, help!

I recently broke my captivate and got an Inspire 4G. I am noticing a big difference in signal, call, and input speakerphone quality.
I am currently on "H+" and have 1-2 bars at my house. Most times I can't even get a text message to send without hitting "retry." In terms of call quality, I usually have to walk around my house to find a good spot. When I put a call on speakerphone, I can usually hear the other person just fine, but they usually can't hear me at all (its almost as if on my end im not in speakerphone).
I'm really worried because I have some phone interviews coming up, and don't want this phone to negatively affect me. Is it because its in "4G"? Is there a way to set my phone to 3G for better coverage? Help me! At this point I don't care so much about data speeds as much as call quality.
For the record, in all other areas the Inspire is much better than the Captivate IMO.
Flash this:
http://forum.xda-developers.com/showthread.php?t=972725
The speakerphone on the Inspire is on the bottom so thus when you on a call, turn the phone over and the speaker phone will become louder. I had problems with this and tried it once and people could hear me. With the phone facing up and on speaker, no one could hear me. But then after reading on here and on the net, I found out that placing the Inspire facedown will allow the speakerphone to be louder. Hope this helps.

Did u do the swap at an ATT store? I would try replacing the phone... my first had similar issues, along with the proximity sensor being borked..
Then flash the ota update by HTC (in settings WiFi update) you shouldn't have to flash anything for the phone to work out of the box.

I got the phone about 3-4 weeks ago at best buy. Could I really see a drastic difference in signal quality if I got a replacement? My phone is completely up to date. I just don't understand how I get such a huge difference in signal quality compared to my captivate.

[Idea] Super Antenna

I was wondering seen as how we have an external antenna couldn't you build something that attaches to it and improves phone signal or make a cantenna? Any suggestions on how to do this?
Sent from my HTC Sensation 4G using Tapatalk
I don't know how much help this will be but I love the DIY spirit so here are some of my ideas.
Connecting to the existing antenna array could be achieved by attaching wires into the existing contact points in the back plates, then route through the camera lens opening out of the phone. The wires will have to be thin so that is something to consider. i.e. more fragile at longer lengths.
The new antennas could be based existing off the shelf parts or from existing DIY projects for each respective technology, but AFAIK you cannot use a single cantenna type device. Due to the different frequencies used for WiFi/Bluetooth vs. GSM vs HSPA+. I am unsure about how many you will need as a minimum or if there are special power requirements between the different technologies involved here.
Power will have to be another consideration. Not 100% certain, but I believe to get these "super" antennas to be truly super, you will need to increase the power to them. This will of course lessen battery life. So that would be another consideration. This mod might spawn a separate battery mod/swap.
I am not sure if this is cost effective or not, but DIY doesn't always consider cost. Of course if you are planning on using this to power some autonomous super killer robot, that can record in 1080P, and stream back live VGA video using the hardware built into the phone this could work out pretty well.
What if you somehow took gold wiring like on the connectors, attached it to the connectors and ran it along the inside of the back cover?

I think the one above the camera hole is for wifi because I saw a youtube video of a guy that took some tin foil and stuck it in the hole on the phone where that connector would make contact and it gave him a really strong wifi signal. He took out the foil and the signal dropped. So I'm thinking that the connector on the top is wifi. The strange thing is I also have an unbranded euro/asian sensation and it has one less connector than the TMO us one (but uses the same mobile bands/radios) and when I use that cover on my US sensation there is no signal difference. So I really wonder what that extra one is for, since I have noticed no signal difference when using one over the other on the US phone.
Hey guys Ive been giving this some serious thought and here are a couple of my ideas on this....I am looking for some serious Beta testers for my ideas, there is no money compensation for testing just fame and prestige......PM me if your intrested in beta testing for me..hurry I have a feeling a lot of people are gonna want in and space is limited.

I think the one above the camera hole is for wifi because I saw a youtube video of a guy that took some tin foil and stuck it in the hole on the phone where that connector would make contact and it gave him a really strong wifi signal.

Maybe T-Mobile uses AWS bands for HSPA+? I'm not sure if that's even possible, but I don't know much about that stuff.
Anyway, I believe the antennas are:
Above the camera: Wi-fi
Below the camera: BT? (correct me if I'm wrong)
On the bottom cover: Mobile network
And @joemm Lmao!

No, My Asian sensation has the same bands as my tmo sensation. It has the AWS band and gets the same download speeds as my TMO version. If it wasnt the same bands I wouldnt even get 3g, I would be stuck on edge. Tmo's 3g and 4g(HSPA+) run on the same frequencies. So if you have a phone that doesnt have the AWS band and the phone supports 3g and 4g you will only get 2g speeds. I believe All the the sensations first released had the AWS bands. I think only now are they starting to release versions with different bands. I know a while back a sensation passed through the fcc with att bands. Maybe those are the ones we are seeing popping up on Bell now?

Not only would this work!! It would stop the Aliens from reading your mind!!!!

Hmm, not sure how good this idea would be, but it's worth a shot
I'm thinking as the antenna has to be of a specific length to work, this length is determined by the frequenzy of the signal
Here is some examples : http://www.air-stream.org.au/wavelength

This helps alot. I guess the only thing to do is to make an extended anttena and keep sticking it on contacts till i get better signal lol

What if you somehow took gold wiring like on the connectors, attached it to the connectors and ran it along the inside of the back cover?

I was toying with this idea after I noticed the sub-par data connections I've been getting. Maybe there will be a new radio after we get s=off. Here's hoping...

I have a new back cover coming and I might due some experimenting with the old one.
ive stuck tin foil in the back of it touching th ebottom two connecters and ive never suffered from death grip since , going on 2 weeks now :0
It should be possible if we could get a flexi pcb that we stick inside over the exisining connections and route outside and fold around that sticks down. I dont think we need more power, just a increased area. Should be easy to do.

[Q] Galaxy Tab 2 7 Wifi antena issue? Death Grip

Similar to iPhone 4, the wifi bar drops when I grab lower left corner in portrait mode. It doesn't seem to drop the connection completly but the bar goes down from 5 to 1..
Does anyone have this issue or could it be specific to my unit? Ready to swap if so

Crap! You are right! Happens on mine and on my buddy's tab.

It is on the same side with sd card slot. Assuming that wifi signal goes down by grabing where the serial number sticker is in the picture. If it is a device specific issue I will return mine and swap it.
Pls share your story to figure if it is a design issue that all sgt2 7 have this flaw.

Correction. It is bottom left corner in the picture above. In the picture the main camera is on the top right.

happening on my tab also.
I am going to swap it for a new one. I will post if the death grip issue exists.

Get the app "wifi analyzer" if I turn my tab upside down it sees all my neighbors networks not just barely picking up my own...

Thanks for the suggestion. w/o death grip: -40dBm. with death grip -70dBm.
This confirms it and the signal drop occurs in a couple of seconds.

My tab has *EXCELLENT* wifi reception... when I hold it in portrait - upside down.
Only slightly less better in landscape either right side up or upside down. Seriously. Better even than my Droid X.
They had to put the antenna(s) somewhere. Leave it to an engineer to pick the worse location.

Thanks and it justifies the swap to new one. I am actually glad to hear that it is not an universal issue.
Sent from my GT-P3113 using Tapatalk 2
The signal drops if I hold it along the lower left side in portrait, but I don't loose connectivity. While they could have put it somewhere else, the best place would be where the power and volume buttons are, but the buttons probably prevented that. If they put it anywhere else, there would be an issue with poor location when being held, or loosing signal while being held.
Swapped with new unit and the problem does not occur at the same level. The signal strength does fluctuate but within a smaller range than the previous one.

Good to know. Droping almost all signal is crazy... Mine drops one line; that is to be expected at some point.

My tab also suffers from this death grip problem
Connection strength drops from -52 to -72 when I hold it the bad way.
Couldn't they better isolate the antenna ?
Otherwise it works perfecly fine.

They could. Right up to the point where it doesn't work at all.
RF layout and design is a fickle thing, where everything becomes a series of trade-offs. Personally, I'm amazed that works as well as it does.
For a living, I do PCB layout and manage/maintain an ECAD library. I recently put a part in the library - WiFI/Blutooth antenna chip. It's a tiny, really tiny thing with the inputs on opposite ends. At the time, I notice the datasheet said both inputs were GROUNDED. (?!?) I brought it up to the tech that submitted it - who called the manufacturer and we determined it was not a mistake. I did the layout, the boards were fabricated and assembled, and it works perfectly. It's just a mystery of modern RF technology.
I've spent some time with Samsung support. This is what they had to say:
Visitor: It sounds to be a hardware issue at least in my opinion... something with the antenna placement, bad isolation or something...
Samsung: Thank you for holding.
Samsung: Thank you for bringing the issue to our notice.
Samsung: I will make sure that the concerned department hear regarding this issue.
Since everyone sees this as a huge problem, where do you want to put the antennae that it wouldn't see a drop in signal during use? Put it at the top left, and it's going to be on the very bottom during landscape use and likely see issues. Put it on the top and you loose signal during landscape use, plus you have to deal with the headphone jack. Put it on the bottom and you need to move the USB connection and speakers, and you would deal with signal loss during landscape use. Put it on the bottom right, and you loose service the same as you do now. Put it on the top right, and you have to deal with the power/volume buttons and the IR blaster. So where does everyone want to put the wifi antennae then? A dongle that plugs into the device?
Be a left handed person
At least, top left side is less touched than other place unless move the power button and put WiFi there...
Anyways the intention of OP was to figure out if it is a design issue or a flawed device case. At last we know what it is and have some piece in our mind by admitting it as it is.
Knowing that Kindle fire has a similar form factor and use scenarios, I wonder if Kindle fire also shows the same death grip case.
Sent from my Lumia 900 using Board Express
If it were an issue with the case, you wouldn't see any change in signal, or you would have terrible signal all the time. It could be considered a design flaw but it is likely a design compromise. It could also be that they tried to put the wifi antennae elsewhere, but found that it had the best performance in the current location.
