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

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!

While I'm holding my phone in my living room (both hands on the bottom half of the device.)

 

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.

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:

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!

    • Just revisiting the RCS issue and discussing another point I find odd.  Yeah, my family and close friends and most coworkers still mostly use whats app in our chats due to the odd RCS issues.   Some have Apple phones, some Samsung.  But using Facebook Messenger or Whats App handily eliminates those issues.   But the other thing I find odd is how all the information out there states that to use the Smart View app to mirror your phone to your TV that your TV and your phone have to be on the same wifi network.  That is 100 percent untrue.  I've historically not had wifi at home and only use it in our common areas in our community or occasionally at work.  But primarily I just use my phone for everything and do not have wifi at home.  It's because I haven't needed it.  I've been using all my Samsung phones for the better part of a decade now as my entertainment center because it's simple, effective, portable and absolutely does not require a wifi connection for my TV in order to cast all the content from my phone.  I'm not sure why it is stated that it is required.  The two devices - as we all no doubt know - create a wifi direct connection between the two devices in order for smart view to work, however, no general wifi network is required at all.  Again, I've been enjoying the feature for close to a decade but I find it odd that they say that you need wifi at home to use it.  Samsung television sets, Roku TV sets, LG TV sets (I cast to all of them at work regularly, again, sans wifi) and TCL TVs are all compatible.  There are likely more but these are the ones that I regularly screen mirror to, again, without the two devices being on the same network (this is separate from the notion of creating a wifi direct connection between the 2 in order to enable the service). This is the sole reason I only buy Samsung phones.   I tried a Pixel device before the Pixel 8 (which was the first to allow display out via wired connection for streaming) but it simply did not offer the same feature.   I wonder why they say this.  It's interesting if nothing else.  
    • Yeah, I probably see it through a Washington/Oregon market lens. And maybe a little Nebraska too.  These are the only places I have monitored Tmo overlay of USC closely. Tmo has already added service on 80% of the same towers that were unique to USC just 5 years ago around here.  The 20% left are either too close to an existing Tmo site, or, probably already on Tmo's plans to collocation.  But there is one USC site on the beach where our family likes to go that I am dying for Tmo to add service.  There won't be a lot of new coverage added here. But I have not done really any review in other USC areas.  But I definitely think it's a good move. Robert
    • Found Ericsson C-band+DoD in Brooklyn. What tipped me off was when I mapped a new eNB in this area on Halloween but I didn't see any permits for a new site in the area and the sectors I mapped matched the existing site that was there. Drove by it today and sure enough it's an Ericsson C-band + DoD site, likely one of the first in the city.  This is eNB 110340, formerly eNB 115257. — — — — — Also a T-Mobile new build in Queens. The permit for this one was submitted last year as a replacement for another monopole that got demolished nearby. It must've only recently got installed because it was offline when I drove by it.
