[Q] Radio signal quality - G2 and Desire Z Q&A, Help & Troubleshooting

Has anyone else noticed the radio in the g2 is flakey when it comes to holding signal? My new g2 keeps going from H to E, while my slide holds it's 3g signal solid (they are next to each other on the desk).
Anyone else notice signal issues like this?

[Q] What could be causing Data/3G connectivity problems?

So I recently was able to replace my Samsung Fascinate because of the ED05 Update not fixing the missed call problem.
I recieved my DInc2 yesterday at 3pm & have noticed that it takes a minute or more to open links from Twitter in Dolphin browser hd and that the 3G icon and bars fluxuates from no bars, no 3g icon to full bars to 2 bars etc..
Just wondering if you guys no of a simple fix, if its a known issue, and your thoughts
Thanks

If you're not in a very well covered area, it seems the Inc2 doesn't work so well. For me, being in a well covered area, data functionality is actually exceptional (2mbit speeds not uncommon, usually 1+mbit in most areas, and only a few areas under 1mbit).
This seems to stem from the type of antenna being used. There is a discussion on trying to figure out the best/easiest way to fix this. So far what has been tried is aluminum foil in the back cover (this doesn't seem very well substantiated), small bus/magnet wire (personally tested and works to boost signal, but may not be worth the trouble), and the possibility of conductive ink to extend the existing antenna (possibly the best solution...if it works at all).

Signal strength issues?

I am not one who has run into the LOS just yet, and here's to hoping I don't.
However... I do have terrible signal pretty much inside anywhere. Outside or in the car I have had pretty decent signal everywhere I have gone. However whenever I am inside pretty much anywhere I get 0-1 bar at best, and often even roaming does not function.
Is anyone else experiencing anything like this?
Is there any development for fixes for improved signal/antenna? Is this even possible?
Thanks a lot for everyones time.
That sounds pretty bad. I did notice that the Epic 4G Touch's signal strength is often 1-2 bars lower than the Evo and Evo 3D. This does include inside locations, so I've resorted to using Google Voice for texting and Groove IP for phone calls when I have Wi-fi.
Maybe take the phone to a store that has the same phone in stock and compare signal strength?
I just got this phone a few days ago switched from Verizon and this thing is always roaming im outside at a dog park and its roaming this cant be sprints service im guessing horrible signal strength.

Bars are not a comparison of signal strength between phones you have to look at dbs

I just got the phone a couple days ago and I was having the same issues inside my house. I could not even get the xda app to load. I took out the default proxies and it has helped, at least it feels like that to me.

This is a well known issue that's been talked about since its release. Hopefully it will be on the list of things they try and fix in they first OTA update along with LOS and Android OS
Not saying this applies to everyone, but I figured out why the particular E4GT I was testing had such jumpy signal levels. I was doing side-by-side comparisons with an Optimus S using menu->settings->about phone->status.
It appears the E4GT has very little granularity with signal strength reporting. It only goes by increments of 5 dBm, whereas the Optimus reports signal levels at a granularity of 1 dBm.
For E4GT, -106 dBm = 0 bar, -101 dBm = 1 bar, -96 dBm = 2 bar, -91 dBm = 3 bar - 86 dBm = 4 bar, -81 dBm = 5 bar, and -76 dBm = 6 bar.
Problem in my main test area is the signal is somewhere between -93 dBm and -98 dBm according to the Optimus S. Whereas the Optimus S can react to small changes in dBm with equally small changes in reported signal strength and "# bars", the E4GT tends to like jumping from -91 dBm to - 101 dBm and back. It only reports certain discrete levels and it appears to be rounding up and down (based on side-by-side signal comparison to Optimus S) They both go up and down at roughly the same time, but Optimus S does it smoothly over time. E4GT just does the signal change reporting very abruptly with 5-10 dBm jumps.
Second thing I noticed is hand and phone positioning really affect the signal strength. The antennae/transmitter appear to be at the bottom hump on the phone. If I place my hands over that area holding the phone normally I can go from 3 bars (-86 dBm) down to 0 bars (-106 dBm). Data starts getting very iffy at -106 dBm but still kind of works, just real slow. If I hold the phone in the middle or near the top, I almost always get the same or better signal. I also found the phone gets the best signal when it is held flat, rather than perpendicular to the ground. In fact the best signal I get is when I'm not holding the phone at all, and instead lay it flat on the table.
Again, I'm not saying every phone behaves this way nor am I saying this explains everyones' signal issues. I'm just relaying my experiences.
BTW the signal levels when laid flat on a table side-by-side to the Optimus S is very comparable, almost the same (minus the lack of granularity). However when I'm holding both phones, the E4GT has generally 5 dBm worse signal, sometimes 10 dBm if I'm holding normally and covering the bottom of the phone.
That is very interesting sfhub.
I really hope the OTA has some bearing on these issues. I really wish it would come out sooner than later. I have another week or so to decide to keep this phone or not and really don't know regardless of if an OTA is released whether i will keep it or not.
There is a lot to like and a lot to drive you crazy about this phone.

GN Wifi problems, caused by casing?

I've gone through and read about problems with the wifi on the GN, how its weak sometimes.
But what I've noticed is that it has terrible reception when I'm holding it in portrait view (about 1 bar) but will jump up to full bars if I hold it in landscape or set it down.
Could it just be my phone or has anyone else noticed this?
I'm running Jellybean, Are you Jellin rom I think. Applied the Wifi fix there was for the rom, but still get bad reception on it at times.
Depending how you hold it, you'll be covering the WiFi antenna more or less. This is completely normal. The iPhone 4/4S isn't the only phone that suffers form antenna issues when holding it "the wrong way". All phones will see degraded radio reception of some sort when holding it that way.

[Q] WiFI signal weak

I have thought that the signal has always been weak on my phone but seems to have got worse over time. Is there anything that can boost the signal?

[Q] weak signal

My M8 seems to have a weak signal, usually -108 to -114, then it drops to 3G. My old Rezound would always hold a 4G signal in the house, the M8 only sometimes if I'm near the outside wall. Has no problem holding 4G outside -93 to -98. Is there any way to fix this besides buying a repeater?
