Sgs3 has a 'Death Grip'???

[Ascertion]

While I'm holding my phone in my living room (both hands on the bottom half of the device.)<br /><br /><br />When I move both of my hands to the top of the phone. <br /><br /><br />Anyone else able to replicate this

But does it have a "Death Blow"???

I think most phones will suffer from some sort of death grip, you would just have to hold it in an unconventional way which is why most won't know about it.

<br />Why wouldn't they work around this and put the antennas at the top to avoid the hand interference

[digiblur]

Maybe the other diversity antenna is up there? To have diversity you do have to space them out. If you had to ask me, I do wish the phones still had the pull out antenna when you needed to get an extra bit of signal. But alas, people think antennas are ugly, cell towers are ugly, routers shouldn't have antennas, etc, but then they complain because their phone won't work or their laptop won't work in the next room. Maybe it's because they voted down the palm tree antenna down the road and hid their router under the kitchen sink!

I don't understand this post.

You're obviously holding it wrong:). Antennagate redux, except since it's not an iPhone, the pundits are not going to pounce on it. All phones have the same problem to some degree, some more than others.

I hold my GS3 a certain way and the 1x signal goes down, but then the 2nd 1x signal goes up. So it really doesn't matter, all things considered.

 

Also, when I do my device testing, I test them being held and on a flat surface untouched. I can tell you that every device I've tested is affected by being held, especially the Viper. That's why I test them both ways.

The aosp Roms for the gs3 must disable the second antenna unless the signal threshold it displays via android status bar is not programmed to display the signal strength of the secondary antenna.

Every phone will have this issue when you COVER THE ANTENNA ENTIRELY with absorbent material (like your body).

 

If anyone wants, I can tear just about any phone apart at work tomorrow and post pics, labeling what I know along the way. Can't upload them at work, S4GRU is blocked as a sports site (WTF?). Carrier-specific versions often are different from each other. The iFixit GS3 teardown for instance is for a GSM variant which is different from Sprint's.

hmm I did this. Smae results

If you look at the antenna diagrams for the S3, there is a receive only LTE antenna at the top of the phone, plus the Wifi/Bluetooth antennas on the top right of the phone. The 1X/EVDO and an LTE transmit/receive antenna are on the bottom. The reason for this if I remember correctly, is that most people hold their phone near the bottom when they are browsing/playing games (using data), so wifi and LTE receive antennas are on the top. When you are holding the phone for a call, you are more likely to be holding the headset towards the top, so they put the 1X/EVDO antennas near the microphone, where you are almost sure not to be holding the phone.

 

Here is an image of the antenna locations on the phone:

Yep, that's what I figured for the antenna placement as well.

And that is why they invented 3G

Has anyone else noticed that the GS3 LTE receiver seems to be somewhat directional: When I aim the left side of the phone toward where I think the tower is, I seem to get about a -5 dBm RSRP signal strength improvement. Based on the diagram that Thomas L. posted, this seems plausible. I live in a somewhat fringe LTE area at the moment, so it may be just my imagination. I would be interested if anyone else has had the same experience.

I've observed this with the Note 2 and my Nexus 4 as well.

I sense a Fox News headline coming: Samsung Galaxy S3, the left leaning phone for liberals.

Let me know when it builds a DEATH STAR!
