Hi
Is anybody Else experiencing "deathgrip" issues with their S3?
Been all over the internet and found a few posts about the issue but nothing really helpful.
Any tips? Any ideas? Aside from using my phone upside down....

First I've heard of it so probably just people in a bad signal area and adding 2 and 2 to make 9.
I have 2-3 bars if it lays still on the table or I hold it upside down, if I hold it any way a normal person would it goes to hell.
This is in areas with poor reception but all tested numerous times in the same area. My girlfriend has a xperia s and she has no problem what so ever. My Nokia work phone also works flawlessly.

Very strange, personally i'd be thinking some local interference, is this present everywhere or just at home??
Hmm. So far so good here. No drop in dB with my hand covering the bottom area/bottom back area(s) of the phone.
some people just absorb RF more than others.
this is something i've encountered a lot at work with people using wireless microphones, guitar wireless systems and in ear monitors. certain people just cannot use this stuff because their bodies just absorb so much of the RF that the gear becomes useless if their body blocks the signal in any way.
it's a nightmare to try to explain this to some idiot who just expects his wireless mic to work absolutely perfectly from 600 feet away in a field.

Mine is a nightmare it works fine in my right hand the moment I switch to the left my voice fades in and out and people cant hear me. The problem only seems to have happened since the software upgrade and my wifi is now much better than before so can't help feeling it's something the software has introduced
If you watch the S3 disassembly video you can see that it has several antennas, so I don't think the death grip is possible with this phone..

My colleague just suggested eating less spinach. That way you lower your iron contents in your body
Guess I absorb all RF coming my way then.
But my wi-fi has lower signal strength on my S3 compared to my old Incredible S too which made me want to ask if there was only me who had the problem

Then how do I deal with Bluto?
Did a test while checking the signal strenght. -89 dBm 12 asu holding the phone upside down, -103 dBm 5 asu while "death gripping" it.
I dont know how "audio db" translates to "signal db", but surely my signal can't be 32x worse while "death gripping" it?
(Rougly calculated on the basis that every 3 db indicates a doubling in signal strenght)

I'd like to re-bump this issue, seeing as how I experienced it too.

This might be a poor signal on top of the issue seeing as how its not happening to everyone. I managed to replicate this three times with my hand on stopping all signal until its released and bars are back to full.
Go to settings - about device - status. Then take write down your signal holding it normally and upside down.
If you do this we can compare the change in signal strenght on our phones.

Normal -84 dBm

What kinda signal was that? 3G? I start to think that this is a problem in places with edge/gsm aka poor reception to begin with.
It also needs about a minute to update properly when checking the signal.

"Tests carried out by NordicHardware show that the HTC Sensation 4G loses WiFi and Bluetooth strength when gripped in a certain way. Using a signal measuring app and regular audio apps, NordicHardware shows how the HTC Sensation 4G rapidly loses Bluetooth and Wi-Fi signal, even if its just sitting flat on the palm of your hand.

Will we see a similar issue with the evo 3d?

The sensation's antennas are built into the back plate while the Evo's arent. Still, you would think HTC would have learned from apples mistakes...
I quickly lose Bluetooth connection on my Evo 4G when holding it in most positions. It cuts in and out just bouncing around in my pocket.
Seems like something you would test before you release a phone. Still surprised at what gets over looked.

I don't have my pre-production EVO 3D, but a test Sensation 4G. I did the death grip 4 times, and nothing happened. I've never encounter that mistake on any HTC device I've had in my possession. Then again, why would I hold it that way? I take those test as if Apple are suffering with that mistake, Android devices must be suffering with it too. That's my opinion, because this is the first time I've even heard of this problem.

Really? Let me try doing it with 4 different devices. Is it WiFi and Bluetooth both on, or is it separately?
Edit: Tried the Thunderbolt, Sensation 4G, Inspire 4G, Droid Charge, and the trusty EVO. WiFi and Bluetooth : no problems.

I just noticed that when I put my hand around the bottom of the phone my signal drops by 2-3 bars and as soon as i remove it, it goes back up. I can do it over and over again. Just out of curiosity I tried this with my evo 4g and the signal doesn't change. I've seen a bunch of people reporting that their reception isn't as good as other phones with the 3d. could it be the antenna placement just like the iphone 4?

No, for real though, the iphone had the issue because the antenna was built into the actual outside of the phone, when your skin touched it, it would change the attenuation which caused the issue of poor reception. Our antenna is totally internal so this would not happen.
I think your holding it wrong. Seriously though I just did the same and was unable to recreate the issue. Might be defective.

I have this problem too... Anybody claiming they don't have this problem are in a good coverage area. If you download the app open signal maps you can see the drop in dbm once you hold the device, it's very irritating
Mine does it to, very annoying.
I saw somewhere in another thread that the radio antenna is indeed on the bottom of the 3d. Dont know if thats confirmed or not. But it would explain the drop when covered by hands.

61% with nothing touching my phone.
70% with my hand covering the bottom.
56% with both hands around the phone.
I fail to see how this is like apple because EVERY PHONE loses signal when being touched. The problem with Apple's was that it dropped the calls.

Yes, without anything it's at 80% and once I grab it it drops to 30%. The antenna does seem to be at the bottom unlike the 4G which was on the top.
And calls drop all the time.

My problem is that if I cover the upper part but well I almost never do that.
This needs to be recognized as a known issue since it has been brought up many times
I noticed the same thing but wierd thing is sometimes it happens and sometimes it doesn't.
I could recreate it for 15 tries in a row but then I closed the internet browser and moved the phone a couple inches and the problem stopped.
I will keep monitoring the signal while I grab the phone and see what happens. But yes it did happen when I grabbed the bottom.
Mine does it too...this is the only problem I have

Its not a "known issue". It just so happens that this is a cell phone. Which has antennas. Which, when covered, loose reception. No way around that. Its the nature of cell phones.
Comparatively its like complaining that when in a lead lined room, you have poor reception.

The iphone issue was caused by them leaving the antenna exposed on the outside of the phone. Whenever you would touch it in a certain spot it would short it out and you would lose the signal.

While it may not be exactly like the iphone, could it be similar in the fact the antenna placement isn't optimal? I think that most people hold their phones toward the bottom where the antenna is where as on other phones like the evo 4g they wouldn't be covering the antenna by doing this. I just know I've seen quite a few complaints regarding reception so this could be a feasible reason why.
Forget all the hype on GPS issues... I've been traveling between PA and NY without any other means of navigation help for the past 3 days...relying solely on my GS2 to get me to and fro many destinations and is yet to fail me... I know, pretty risky and I myself even doubted it's reliability considering we've all been stuck on "searching for satellite " at one point or another, but I'm pleased to say that this device performed well above expectation.... Running Unnamed 1.3.1.... share your thoughts on whether or not you'd put road trip on the hands of this beast.

I would definitely rely on my gs2 for navigation. I already have used it a bunch and its been completely flawless. Its so smooth and fast and pretty accurate. My only complaint would be that if you get in an area where theres no data, you might be in trouble. Other than that, it works really well and I would trust it without question.
I can say from my captivate that thing was not reliable however my gs2 has never let me down once!

I have replaced my GPS with my GS2.
The Infuse had almost replaced it but it was semi-"meh", but the GS2 is rock solid.
My only worry is the data dependency - but I've got a Wilson amp in my car and the end result is incredible. I get 3-4 bars of 3G in rural areas I used to barely get 1 bar of EDGE in.
I wouldn't hesitate to use it for travel. It's rock solid compared to the Captivate it replaced. The GS2 locks fasts and stays locked.
If I trusted my 3gs for years I can definitely trust this one which I have ever since I got it.
I am actually in love with the navigation on this device.
My GPS has worked great. When I'm not using navigation, I use it as a speedometer
Sent from my SAMSUNG-SGH-I777 using Tapatalk
i wrote a speedo app that shows my speed in the notification bar while i'm navigating. Any interest in that? I'm thinking about publishing it on the market.

The only thing I don't like is that it clearly has static navigation enabled, which makes it suck for geocaching.
Gonna have to figure out where I put my Oregon 300...

Which amp? Using an external antenna?
I'm kind of rural myself, and with all the hills around me, there are quite a few RF nulls. My only problem is that I'm not sure I could attach another antenna to my car without interfering with each other. Perhaps their "low profile" antenna (that seems to stay inside the car) would work.

http://www.amazon.com/gp/product/B0011GI94Q is the amp I use.
I have the outer antenna near the rear of the roof of my Subaru, with the inner antenna velcroed to my dash. I have my Samsung car dock set up so the phone is RIGHT above the inner antenna.
People with sunroofs may have issues with the inner and outer antenna coupling to each other.
It really works best when the phone is within a foot or so of the antenna (esp. within a few inches)- any farther and the gains are not nearly as great. Putting in a higher-gain amp would ease this limitation - but in many vehicles would be even more likely to start oscillating due to feedback.
I'll try to take some pictures and post them this weekend - if I don't freeze while taking them.
It's pretty good so far.
Still evaluating the advantages/disadvantages and comparing with other portable GPS devices.
I've replace my GPS and my camera with my sgs2. This thing never seizes to amaze me.
Sent from my SGH-I777 using xda premium
GPS - yes.
Camera - no... No way it'll ever replace my K-5. Every time I've used the camera I've been sorely disappointed. It's better than any other mobile phone camera I've used before - but that's not saying much.
My GPS has saved me many many times. GS2 GPS for the win!
My phone has stock 2.3.6 with root. Other than that, it is totally stock. I use my phone in my job to provide GPS coordinates for natural gas tie-ins. Quite often when I open GPS test or GPS Status to get the coordinates, the GPS will locate 7 to 10 sats but will not lock on and give me my location. Re-booting the phone will solve the problem. Google Maps also does the same thing. I believe the phone was doing this before the update.
I don't know if it happens to you guys or not but me, yes, as soon as I reported "GPS works great so far", it let me down right away.
On my way home in the evening, turn H+ on, turn GPS on. While talking on the phone, I opened Maps and navigate home. Sitting in the car for 5', no sat. locked. Started driving until half way home, still not locked. Stopped in the parking lot, wait for signal again, 10' later, still not locked. Very frustrated! Grrrr
The last two nights, I woke up to my phone causing my alarm clock to buzz continually. Whats weird is that the phone was about 3 feet from the clock...I wasnt receiving a call or anything...
The only variable I can think of is that I have started running MIUI. Could this effect my phone in some way?
I dont know, this may be a dumb thread but when my phone is buzzing out my alarm clock from over 3 feet away, it makes me cautious about putting the damn thing against my head. Watch out for those radio waves guys.....thoughts?

Turn off your phone lol. I was a sound guy for seven years before the recession. This is one of the reasons they tell you to turn of your phone in a theater. Not only can they run on the same or similar frequencies to wireless microphones, they also interfere with speakers. And yes, it doesn't matter if your phone is receiving a call. Sometimes it has to communicate with the towers. Long story short for my sleep muddled brain...turn off your phone or move it to the other side of the room

Thanks! I guess the main concern is that my phone has never messed with my alarm clock before, I never turn it off. I was also on a CDMA network for a while, Im somewhat new to ATT. Are phones more buzzy on GSM networks?
I dont know! I just have this weird fear that say if "something" was wrong with my phone it could emit more radio waves than it should normally. Its one of my partially unfounded scary thoughts. /blush
I'm honestly not sure which network type would create the most interference. I wouldn't be overly concerned about it. Its just the wave shaking the speaker (to put it in non technical jargon). Pretty sure it has more to do with frequency than the strength of the signal.

The TDMA-based modulation scheme used for 2G GSM is notorious for "GSM buzz" at the TDMA frame repetition rate.
3G shouldn't be causing such things but 2G will.

Interesting, good to know.
A little more detail:
With classic GSM, the scheme for allowing multiple handsets on a cell site was to assign each handset a time slot to transmit in. When it was that handset's turn, it would transmit a short burst in its timeslot. The end result is that with GSM, a handset's transmitter pulses on and off rapidly. Many other electronic devices have circuitry that acts as a rudimentary RF detector and demodulates the "on/off" pulsing.
With CDMA-based systems (either cdmaOne/CDMA2000, or UMTS), fancy math is performed such that handsets transmit simultaneously and semi-continuously when talking to a tower. As a result their RF envelope is constant and doesn't demodulate to audio frequencies with simple envelope detectors (which is what many speakers and audio amps behave as with interference like this.)
Thanks for the info entropy. Always wondered what exactly the issue was.

Turned around and after about 5 mins found the phone and its case, (still missing my sd card and battery,, it was about midnight) went back the following day and found the sd card and battery, unfortunately the screen was smashed and the lcd was also cracked it powered up but there was no picture, i have noticed after further examination that along the bottom of the handset on the back just above the charging port there is a crack in the plastic and a bit is missing and you can see two springed metal connectore, now whether these connect to the antenna for network or not i do not know, ive been googling non stop and the general idea seems to be imei problems??

Mobo could be damaged. Either that or the antenna is missing. The antennas are located on the right and top of the moon. It is exposed when you change the LCD. If you switched it yourself, check those connections. It's pretty easy to check it.
Right and top of the moon? Also the phone works perfectly if not faster than it used to wifi Bluetooth etc all works is the antenna with the wire that runs down the right anything to do with it ?
