So let me start off by saying I've used both stock Gingerbread, and ICS probably about equal time each so I'm used to the signal behaviours of each.
My signal was always bad where I am at University and all of my flat mates had great signal (3G, HSPDA). I took my phone in for repair and they replaced the main board, they also reinstalled Gingerbread, even though I had already S-ON'd unbranded etc etc.
My signal was great and I could use my phone properly again, internet everywhere and it was amazing.
Now I have my new SD card and I've just rerooted S-OFF'd etc and now my signal is playing up. I thought well hey if ICS is coming out soon why not just install it now anyway, because if my signal is bad on ICS i'll know it.
My question is what is your signal like since upgrading to ICS, if you have that is. I'm averaging 2/5 bars of HSPDA whereas before I was getting 2/4 HSPDA, and the overall loading is slower.
I'm running latest Insert Coin with the firmware from the user-friendly firmware thread.
Any help/tips or insight on the matter is greatly appreciated, also this is my first post so I'm sorry if I missed something.
tl;dr, since upgrading to ICS signal is crap, what's your signal like if you run ICS.
Edit 1: Done some things and found stuff out.
It seems to be for sure that ICS is to blame for this, although I'm getting weird results. I installed the ROM from MrT's (I think that was his name) and my signal did improve slightly, from 0-2 asu up to 6-8 asu, although it still fluctuates. I've tried ARHD and IC both have bad signal (definitely NOT the developers fault I was just saying).
I am gonna try the OTA next and see what the difference is. I mustn't be the only person who has much worse signal on ICS. There is zero point reverting to S-ON and going to GB, because we'll all be getting ICS this week or next anyway.
Will keep thread update in case anyone else has similar issues that they wish to fix.
Edit 2: I reverted to stock GB and then used the OTA file so now I'm at official stock ICS untouched. The signal is improved although still not as good as GB. I will wait until the release and see if I receive another update and then edit the OP again.
I also have bad reception and voice calls bad sound on ICS , I didn't use gb so I can't know the difference but on ics is crapy
Bought mine used, and the seller had just s-offed it. Ever since I've had it, all radio reception has been terrible in comparison to my N1, the worst being bluetooth, closely followed by wifi. Cell/data reception is acceptable but still not as good as the N1. I've just ordered a "new" back cover from Ebay in the hope that it's a hardware/antenna issue, I have reason to believe it might be based on the erratic nature of the bluetooth problems.
Should have mentioned first, I'm not running a 4.0 rom yet, I've been flipping between the original T-Mobile Sense g/b rom and CM7. Bluetooth's bad on both, but I've got a sneaking suspicion that wifi is better on the Sense rom, although that might be my imagination.
Thanks for your replies guys.
I will try installing the OTA file, maybe it has something different to the firmware and ROM I am using, it's worth a try anyway.
It's also worth noting that signal does go down upon picking up the phone into my hand. Right now it has 3/5 HSPDA but when I pick it up in my hand, 5 inches higher than it was, the signal drops to 1/5.
I changed firmware to 3.32 and it's little beter now. I think it's radio software problem

Yeah I'm using 3.32 but it's actually worse. I've tried a few different versions I've found around the forum and they're all the same. Signal is fine when not being used but goes down when I use it or hold it in my hand.
I hope the official OTA is not like this or I will have to send it in for repairs again or get a new phone altogether.

Thanks for sharing, how much worse is it? For example with me I used to get about 7-10 asu in network section of settings, now its 0-2.
I guess I will try to cope until it is officially out for the Sensation in the UK and then after I can go into the shop and send it in for repair (second time).
I have the same problem before I used to get 2-3megabytes on speed test and now I'm getting half a megabyte and from the same place in my room where I used to have full 4 bars now I have 4/5 bars and I can't even buffer YouTube video

I have to say that my reception is worse on ICS. I was using gingerbread on sensation, from new, for about a month before I made any changes to my phone (root, s-off etc.) I would get a constant full 4 bar reception, it would never drop. Now on ICS, signal strength flits between 3 and 4 bars frequently, sometimes dropping to 2 or even 1 very ocassionaly. It is pretty annoying.
YES. i am experiencing the same exact problem. i have to say ics has been pretty disappointing. my signal in my room used to be 1-3 with an average of 2. Now its the same, but wit frequent drops to 0. Cmon. crappy browser, bad signal, isnt this supposed to be final version?
ok my receiption is worse at my office.. Not only worse can describe but i kinda suffer cuz of my connection. I think its related to the radio and i should try another one cuz its really annoying
im on ics, suffered the same fate, maybe this is due to DEATH GRIP?

Obviously I can't speak for everyone, but it is definitely not due to death grip with me. I can just leave the phone stationary, not even touching it and I can see the signal strength bars going up and down. I would really like to know what is causing it. I used to have perfect signal on Gingerbread.

i just wish its the ICS problem... i really love the phone, but im a little bit dissapointed as what i see on the google regarding death grip.
Same problem in my S2. I'm in a place which is like a Faradays cage, so signal fluctuates from 0 to 4. My new phone improved performance a lot because signal was fluctuating more quickly. I thought it was the hardware, I was very happy, but after updating to ICS it happened again. I think it's a kind of watchdog for signal, which is slower in ICS than GB. So should be a way to speed it. I decided to go back to GB but I can't: factory reset doesn't return phone to 2.3.5

EE4 wasn't a great modem either. Darn VIA radio.
But the GB builds have an issue with noises in phone calls that is still there in EP4P, if VZW is also seeing that in testing that could hold it up. And if they plan an ICS release for the phone Samsung might not try too hard to fix it - they obviously haven't been able to do so yet.

+1 The noise happens to me on any 2.3 rom, hopefully it's one of the issues they're trying to resolve before releasing gingerbread, though I hate to be part if the reason it's being held up

i think that something is wrong with my phone. It does not like any custom roms. It freezes and acts up often. Once i put the stock froyo or gbread it flies and works perfectly fine..... And gbread 2.3.5 and 2.3.6 were solid with no issues so far.
I think its the modem. I had my first static incall today after running the 2.3.6 leak for a week.
Never had that issue on froyo roms.
Sent from my SCH-I510 using XDA App
There are some problems with this build as well. It seems to mostly be with the radio, echoing what people have said here. I've had a couple times where I could no longer send/receive SMS and had to reboot (where it immediately started working again).
There's some other weird things going on with the I/O. I use PowerAmp for music and I'm getting strange skips and pauses that I never had before. Could just be my configuration, but I'm still running pretty lean.
The latest rumor is that the OTA is happening on the 29th. That and $3.49 will get you a McRib.
GB is alright. They need to fix the freeze issue that has been on quite a few GB leaks. It doesn't happen that much on EP4P but it's still there. The modems on EP3 were great in the sense that the signal was SO much better, it obtained/held 4g with such ease. Then I upgraded to the EP4 modems and i lose my 4g signal like i did on EE4 but my 3g is actually usable now. Before the 3g speeds were so TERRIBLY slow i could never dream of browsing the web on it. These speeds are reasonable and i think these modems are the best so far. They need to combine EP3 and EP4 modems to make a solid, stable 4g connection but a very fast 3g connection when it does drop down. Ontop of all that they still need to fix the ****ty voice issue on all GB versions. EE4 was great with this but the GB modems make the voice quality sound like crap.
So, all in all, even though GB is clearly no where near ready to be launched i still just want them to push it anyway because that means GB source code which means CM7 which means CM9(if we get a dev on it)
I feel as the OP feels. As far as a bad radio, I guess I'm just lucky. I haven't had issues with data loss, crackling noise, Bluetooth problems, or anything else. This phone has been darn near perfect since I got it. The only real complaint I have (which really isn't a complaint) is battery consumption. I wish it was a tad better but I manage just fine. Oh, I do wish there was more memory too. I haven't been able to play a couple games because of low memory. Battery and memory are my only real issues at this point. Still, I'm overall very happy with the Charge and would have no problem staying with it if I didn't have an upgrade available.

The modem is better than before. I'm not saying the modem is good or ready yet, but it is working better than any of the last 2 or 3 that I've tried / used.
I sure hope they don't screw up the O/S portion or give up completely because they radio is crap.

Where did you hear that bro?
This release is solid
I was sick of waiting so I flashed this ROM to my phone and I have had the same results as the op. The phone is so responsive and snappy. It is like a new phone. I used to experience numerous data drops before and now, maybe a few in the last ten days. I have not had any of the static/call issues others have had. GPS is still slow to lock. Download GPS fix from the market and run it before you use the GPS...it helps IMO.
My battery life has improved since porting this release. I am a moderate user (phone calls, text, facebook, twitter, occasional GPS) and I get an entire day from my phone (7:00 am - 11:30 pm). I am sure streaming movies and gaming would cut it down significantly but the casual user will notice a big improvement in battery life.
Again, this is just my personal experience.
I agree that the latest version is awesome.
I guess I am really lucky as I have never had the slightest problem with data, phone call quality or anything else. My phone setup the way it is runs faster & smoother than my bosses Bionic.
The ONLY thing I would change if I could would be the poor battery life, but that's a fact of life with these huge screens etc.

No problem with my Modem. Maybe its your Charge? The leak has been solid for me.
I have noticed the higher latency for sure on the ICS ROMs. I tried ExtremeSensation and InsertCoin, and had the same issue with both. I was around 85ms on GB, and around 160ms, or higher on ICS. I tried stock radios/RILs on ICS as well, and the issue persisted.
This needs to get fixed. Everyone seems to be overlooking it, but several people have said they have the same problem.
not the biggest problem in the world...you can live with it...for now
Yeah. I noticed that too. For me, I typically get around 45-55ms on gingerbread. Ics measures around 110-120. Not a deal breaker but annoying for sure
Sent from my HTC Sensation Z710e using Tapatalk
Yeah, it's almost a deal breaker for me. I have my older MyTouch 4G sitting right here next to me, and it's latency and speed is fine. It's signal does not fluctuate either, like this new Sensation does on ICS.
55??? Mines terrible, 280+ and sometimes it will just sit there, then say my ping is 1500!!
Another vote, mine's a ***** as well.
Yeah, I went back to a Gingerbread ROM, and all was well. Not sure what's up with Ice Cream Sandwich ROMs.

I have slow pings with a Moto G that I bought a couple of months ago. I had a suspicion that the pings might be slow even before I bought it. So I tested, and as you can see from http://forum.xda-developers.com/showthread.php?p=51354213#post51354213, my pings are slow too.
There are two problems with the pings:
mean delay
variance of delay
Both are excessive. Both of these are problematic for certain types of application. Both of these are things that easy to not-get-wrong by a software developer with experience in computer networking. Makes one wonder.
What worries me is that the communication path of general Android applications might suffer the same deficiencies.
Can anyone ping their device and check the delay? Over Wifi with strong signal, you should be getting sub 10 ms times, easily.
First off I apologize if there is another thread about this but all I found when searching was a general "best rom", and one related to battery life.
Personally I would like to know opinions on best rom for connectivity only. I live in a strong 4G area but whenever I am in my basement I get spotty connectivity, drop calls and such. I have been on the CM10 nightlies crack flashing since the boot-loader was unlocked. I love CM10 just wondering for basic call quality, does someone have a different rom preference for call quality?
Again mods I apologize if this is out there... but i couldn't find one for call quality. I realize this all depends on the baseband and such which Samsung is infamous for theirs. I just feel like even a slight better signal would make a big difference for me considering generally it's good connection.
Also my office is in my basement and I make a lot of calls and I'd prefer to keep it that way if possible.
Any thoughts are appreciated.
I'd actually like to know this as well. I recently switched from using an iphone to a Samsung Galaxy S3 and the difference with this phone is there are so many different roms available, I don't know which one is the best whereas with the iphone there is usually 1 main jailbreak and everything else is provided by cydia.
Like you said, this mainly is based on the radio and not on the Rom, but i agree there could be some minor differences. Your best bet would be to try a couple out and see how they work in your office. I personally am running jellywiz and my signal is rock sold and i work in low signal areas a lot.

If you search the forum there is actually a main thread for best rom overall which may help you more since it doesn't seem your only concern is call quality. Sorry I don't have the thread name but I think if you do a forum search for "best rom" you should be able to find that thread.

I actually planned on doing that and testing them out on my own, I was just hoping someone may have some tips on one they have used in areas such as a basement or a place they know they haven't always gotten good service but have found a rom that works great for them as far as call quality. Such as your example of jellywiz, I will certainly give that a try and see if I can hold a higher consistency for call quality. Thanks for your input!
There are definetly differences between ROMs relative to battery life... different versions of the same ROM can be quite different.
I've been using Jellywiz as my DD and it's been great. I really liked RLS4. I've updated to RLS5 this morning but my battery life has declined greatly. I've also gotten one reboot. I'm sure the dev will have it fixed in the next release (the Devs on the Jellywiz project are top notch).
I also liked Synergy quite a lot... It's not Jelly Bean, but the battery life was great and very stable!
The best thing you can do is try several different ones... Let the ROM settle for a good day or two before coming to any conclusions...
Good luck...

Without getting too granular, stock based roms have the best reception. Rom's where the RIL has had to be tweaked, such as CM, MIUI, JellyBean ports, and cross carrier ports are more likely to have radio issues.
Then, there are different radios you could flash. In my experience with many devices, changing radios has never had much of an impact on radio reception. Different radio versions generally fix bugs, and things like 3g/4g switching. For instance the latest stock radio for our device (VRLG7) fixes the "no SIM" bug. I am using that and it has worked great for me.
Generally though, I don't think actual reception (mostly dependent on hardware) should vary too much. Usually it's reliability that can vary. "Bars" aren't always an accurate indicator of reception either, signal strength in dBm is.

Sorry... I got lost in an unrelated thought (battery life)....
The service side appears to be pretty sold from the ROMs that I've personally tried. Not sure you'll find a big difference here in real world performance.

I have not seen the 4G indicator since flashing a week or more ago. I have tried aokp, cm10, and root66.
Not sure what to do. The phone works fine otherwise. All these are great but I would never have gone this route if I had any thought that wireless capabilities would be reduced. Any ideas on how to return to 4G would be greatly appreciated.
Out of all the 4.1 roms out there, JellyWiz's wifi/4G/3g is the most solid one. Very stable and good enough to be a DD.

I live and work in an area that has poor signal for Verizon. I almost immediately flashed to CM 10 after I got the Verizon Galaxy S3 because I was running CM 10 on my previous Sprint Galaxy S3 without issue. I have been updating the radio and RPM with each leak (currently running K3) and things got a little better but I constantly dropped calls. I had to flash back to stock because I flashed to CM 10.1 and my radio got messed up. I ran the newest stock rom for the last week and noticed a huge difference. I still had low signal but my data dropped less frequently and I could actually make phone calls in areas I couldn't before.
I rooted, and flashed to CM 10.1 and noticed right away the signal is not where it should be. I can't make phone calls inside of buildings with low signal at all, where with stock I could without issue. I love CyanogenMod but I don't think I can deal with the poor signal.
Any ideas on what could be causing this problem and maybe a possible resolution?

Depends on where ya live, your mileage may vary. I get within 1-2 -dBm between the two.
Technically since we don't have the source code the reason CM10 has data is by a work around.
There really is nothing you can do. It is what it is. I've run devices with CM that have provided better signal, and usually were on sprint lol and then run them where they provide the same or slightly worse quality.

My understanding is that the CM developers dont have the GS3 source for something (the RIL?) so they have to use a different RIL? I'm probably totally butchering that, because I dont understand the words I'm using, but from what I've gathered the signal is what it is on CM, and will not improve beyond where it is.
It is certainly usable for me, but there are many times my wife has 4g and I have 3g, or she has a 3g signal and I have nothing at all (she has a stock vzw gs3).

I think you're correct on the RIL part.
I had the same issue on 10.1. I switched to an older radio, and though it is not perfect, it did give me better reception and the switch from 3g to 4g is faster. My radio is VRLHE
Why not try a rom like beans. It is a touch wiz rom that looks like aosp and had a lot of aosp features. That way the radios will work fine you will still have aosp stuff and all the goodness of being rooted.
Sent from my SCH-I535 using xda premium
Let's not get confused here. Tw rom's like beans are themed to look slightly aosp, but are far from it. Aosp has so many customization options that tw cannot come close to. (I'm an aosp guy, if you can't tell). That being said, signal strength will always be an issue on aosp based roms due to the Samsung ril only being licensed to samsung, hence only working on tw rom's. The official ril code will almost never be released as its how qualcom makes its money. Currently aosp rom's use a work around home brewed ril that is very effective, but not quite what stock rom will offer. So if your signal is poor where you are, aosp may not be the best choice for you, but for most the signal is just as good as tw, and imo the only way to run android.

I'm not confused, that's why I said looks like (aka themed like). Also I said some aosp features like MMS, camera/gallery, lock screen to name a few. Its no where near the same but if they are having issues which I read a few people do have with signal and losing data its a nice alternative and has SOME similar features.

Why this happens ?
its something with the kernel ? or drivers why no use original ones ?
That's a question for "Google"
Actually if you read the threads taking about this specifically the one by jeffsf he has a theory that Samsung knew many of the devices had crappy WiFi hardware and that is why the device had tons of leaked builds. They kept releasing then in hope of fixing the reception and ultimately just faked a better signal.

There is no super duper trick to get better wifi. What Samsung did was modify the data file to reflect a higher level. It is a visual trick and one that tricks the OS into thinking the signal is higher also so it does not disconnect as much.
What erikmm did before is change the signal bars from a actual representation to a false reading that made people think they had a better signal. Turn off the bars and use dBm readings and you will see the real signal.
This phone has a really crappy radio reception and there is not much you can do outside of what samsung did and make the signal bars read I higher rating. I think it was jeffsf that said the best solution would be to hack the wifi module and make it read all signals at a increase of 5-10 dBm so it wouldnt drop the wifi so often.

What file do i have to edit to get a fake wifi signal read and avoid disconnecting ?
I actually didn't do what eollie said to trick people I did it because of information another dev told me then I gave it a shot I saw improvements for me and thought it might improved but again if it's not you don't have to flash it or complain. Source is out do instead of complain that something isn't working or a mod isn't 100%

Show me where I said you did it to purposely to deceive people.
Furthermore at the time you where posting those roms there was NO source code to edit.
If you are still doing that code modification then you are now purposely deceiving people.
To clarify if people think I was saying erikmm did it purposely then you are wrong. I dont know what his intentions was initially.
First off, I want to be clear, I don't know what was/is different in Erikmm/Beastmode's ROM. At the time it was released, source was not available to examine, and I haven't dug into what has since been posted. I also hypothesize that Samsung was, among other things that T-Mobile probably wanted them to change, tweaking the "calibration" of the WiFi in the various leaked releases and that the "nice" version wasn't in the final release. Considering that the "official" release modem has problems with long SMSs, it wouldn't surprise me that the low RSSI numbers reported weren't caught either. I don't work at Samsung or T-Mobile, so this is my personal speculation and opinion of a likely scenario.
I have tested WiFi pretty extensively and it is my personal belief that the RF portion of this phone just sucks; WiFi, GPS, and quite possibly Bluetooth, but nobody has complained about the last one. Unfortunately, the leaks were hosted on sites later shut down by the FBI so that getting those versions to examine as well was not possible.
If you want to "fudge" the signal levels, the details of one way to do it are in the linked thread. It will require you to create a build environment, populate it with the source of your choosing, edit WifiManager.java, and compile at least the framework. It could also be done within the kernel driver. Since I find that levels below where the current crop of ICS ROMs believe are "no bars" I don't get more than around 1 Mbps over WiFi and I do generally have decent T-Mobile signal, I just use my carrier for data when the WiFi level is low.
