Poor Signal Strength with Cyanogen 10 & 10.1 - Verizon Samsung Galaxy S III

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.
Happens.

This does not ha e anything to do with cm 10. This this to do with the the phone radio. This is the reason why I switched to the DNA now I have Full bars everywhere I go. On my s3 I used to drop calls all the time.

Ok I really hope I'm not beating the dead horse here but I have a similar problem on my verizon Galaxy s3 and I was hoping there might be a fix

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.

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.

[Q] Best rom for service ONLY all other variables aside?

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.
CodefireX is getting me the best service I've ever had. Several other people in the thread seem to be experiencing the same thing.

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.

Cm10 stable builds!

Alright so I just found out on android authority that cyanogen mod just released its stable builds for the galaxy s3 variants. Just scroll down and find d2vzw!

Hate to say it but TW Roms on the S3 FTW.
Nothing more stable then the TW Roms we have for the Verizon S3. AOSP is just not there yet and who knows if it will ever be. After coming from a GNEX, you really see AOSP was not meant for any other devices and is loaded with problems when using anything else then a Nexus device.
Would love to get another Nexus device but who knows if Verizon will ever see one again and no other network is really good enough to pull me away right now.
Also, Google's claim about no LTE on the Nexus 4 due to bad battery, did anyone at Google try the S3? I would hardly call 4 hours of on screen time over LTE bad battery. They need to look past the GNEX which for whatever reason was a disaster when it came to battery. My wife's Rezound with like a 1650mAh battery gets as much screen on time then my GNEX did with a 2100mAh battery. Knock knock, don't we think something was wrong there!
Actually, I used the Thunderbolt I had previous to the GS3 for over a year on AOSP and it was AT LEAST as stable as the stock rom...probably more so. It just took time for it to get there. Saying that AOSP will never be stable is just...well, hogwash...Right now it's questionable. The roms are stable, it's just data that has a bit of an issue. If you're in a great reception area, there's no reason to not use it. Fringe areas, well, there are pros and cons.

I never said it will never be there I said who knows if it will get there. The Thunderbolt was never stable on stock so saying AOSP was just as stable is not saying much. lol
Signal is important to many people. If I was not worried about signals I would not be on Verizon paying their hight prices. I would be paying half the price for service running a Nexus 4 on a crappy GSM network. There are more issues then just signal and sure eventually they may all get worked out but so many people here jump devices so often we never get to see the final product if one is produced.
All I am saying is TW Roms have been so good on the S3 I cannot imagine sacrificing the stability at this point for an AOSP rom and trust me I would love to run AOSP. I never knew how good it felt until the GNEX which was my first Nexus device. Man, did AOKP rule on that phone.
I am currently using this rom. The only problems I seem to have are GPS locks, and the speaker phone echo. Supposedly some work was done on the echo, so perhaps a wipe is need to reap the benefits. At this point, once those two problems are fixed I would consider it a daily driver for anyone.
I don't use NFC or bluetooth, so I am unaware of problems related to those features.
Bass Issue
I'm not really sure if there is an exact stable build since the supposed stable build had Bluetooth issue by not giving the bass

if you search "nfc greyed out" in the question forum youll find pages of results and threads about this, and youll get your informatino much faster.
theres a zip youll find, as well as instructions.
nandroid
flash TW JB rom.
enable NFC (might as well get a GPS lock also)
restore nandroid
win
For the NFC issue, I believe that the CM10 thread includes a flashable zip or APK to fix the NFC: see this thread.
I do have a general question. I have been running CleanROM 5.6 but wanted to know how "stable" CM10 is in comparison to CleanROM. I understand that I'd be missing out on some Touchwiz features (motions, smartstay, powersave), but I am most concerned w/ battery life and data connection, particularly as I find myself never using the Touchwiz features anyway.
I am finding that reception on my S3 is inferior to my Razr M - for example, where I would get 3G or 4G signal on my M, I was getting 1x or no data on my S3. From what I've also read, data on the CM ROMs is inferior to the data on the TW ROMS. Can anyone confirm this?
Also, w/ battery life, I've also read that battery life on CM ROMS is inferior to that of Touchwiz. In any case, I am finding that the battery life on the S3 in general is inferior to that of the Razr M given my use. Specifically, I push my work email, read and respond to emails, browse the web a little bit, a few phone calls and text messages, and some FB use. On the Razr M, I was consistently getting about 36 hours of use, whereas, on the S3, I have been barely able to get 24 hours. If battery life on TW is already inferior to that of the Razr M, I am not willing to sacrifice battery life further by going with CM10.
In addition to battery and consistent data, are there any other bugs/issues w/ the CM10 stable that I should be aware of (tethering, BT connectivity, low call volume, speakerphone echo, etc.)?
Lastly, I assume that CM10 stable does not have the multitude of bugs that the present version of CM10.1 has?

Signal Strength

Why does the Signal suck so bad on the SIII. I am rooted and running the cleanrom with the latest radio and it still sucks.
I ended up retiring the SIII and went back the Mot RAZR MAXX and wow what a difference.
It doesn't suck for everyone. My call quality is better on this phone compared to my incredible. Dbm's are plus or minus 5 compared to the incredible as well.
Sent from my SCH-I535 using xda app-developers app
Well I tested it side by side in several different places here in Florida and this a good strong signal area and the SIII just can't keep up with the Razr MAXX.
You think I got a dud for a SIII and there is probably nothing I can do about it other than get another phone. I can sell it and buy something else.
It's works great is most areas it's just when you get in the areas where it may down to one or two bars. Hell I had two bars and 3G and it won't even send a text. It will fail sending. I use the MAXX in the same area no issues at all.
I feel the SIII has a weak antenna in it.
For me it's not work using. I want a phone that will work in the areas I am in. I never had an issue until going to the SIII

It's a problem for some. I haven't had it ever switch off 4g. Pretty decent coverage all over Indiana. Moto is famous for their radios, its nice you were able to switch to another phone.
Yea I always keep a couple of extra of phones just for that purpose. I tried turning off the 4g and going 3G only still the SIII sucks in certain areas and the other phones have rock solid service.
I think I am going to ditch the SIII soon and replace it with something else.

Have you tried switching out the radio? (Assuming you are rooted/unlocked) I had horrendous data speeds/connectivity issues after the initial JB OTA ... switched back to one of the JB leaked radios and have been blazing along ever since.

Yes I just flashed I535VRBMB1 Radio the other day and it did not help at all...
Please provide links to which radio worked for you.
I am running clean Rom 5.6 right now. Just noticed there is a 6 out now...
So What Radio are you all running that gets good signal?
Just flashed JB Build 12 and if this does not help. This phone will be gone...
Well wiping and flashing JB and the latest radio leak did not really help. The SIII still had issues with signal with the RAZR MAXX did not.
The SIII is nice but not usable to me. Not when you can do a side by side comparison to other device and the SIII can't even keep signal when the other device has three bars.
I don't think the new S4 will be any better.
I might find me a HTC DNA I heard the radio is great in them.
I miss my thunderbolt and good old skyraider... Those were the good old days.

Did you download and install the RPM? I get fabulous reception with my SIII running same SW. I have found that the RPM, helps signal and certainly helps battery life, which makes sense. Try it. Locate and install the RPM that matches your modem.
http://goo.im/devs/invisiblek/i535/rpm
I had the same issue since moving back to an AOSP ROM (Liquid Smooth). One of the leaked radios, VRMBA2, seems to work the best for me with good pings () and DL speeds ranging from 12Mbps - 34Mbps depending on sig. strength.
I did not try the RPM... I will do that now.

Why is everyone still releasing 4.1.2 ROMs?

I just upgraded from a Samsung Galaxy Nexus to a Samsung Galaxy S3, and just curious why everyone is still making/releasing 4.1.2 based ROMs when 4.2.2 has been available for so long?
Having come from running 4.2.2 on my Nexus, I was used to it, so the first think I did was unlock, root and get AOKP 4.2.2 on here. It runs flawlessly and everything works, so just hoping to get some insight on why all the ROMs in the dev section are old.
Thank you
Because many of the roms in development are based off Samsung's touchwiz software, which itself is based on 4.1.2 still. For 4.2.2 roms based off AOSP, most of them can be found in original development.
Basically the difference in versions is due to
Touchwiz: Google -> Samsung -> verizon -> devs
AOSP: Google -> devs
And aosp roms camcorder has extremely low volume recording so having kids I unfortunately cant use aosp even though I really want to.

Not quite everything works on an AOSP 4.2.x ROM. The radio interface layer (RIL) software for the GS3 has not been released by Samsung, the radio software used for all AOSP ROMs is reverse-engineered and is not quite as good as the original Samsung software. Your signal strength will not be quite as good using AOSP, though you may or may not notice a difference depending on coverage where you live.
More importantly, the GS3's world phone capabilities are not fully working with the AOSP RIL, I believe you can put a GSM SIM in the phone and make calls/texts, but not get data service. So if you travel internationally and want to use a local SIM to get data, you'll want to stick with a ROM based on the latest Samsung software, which unfortunately is still based on 4.1.2.
I'm happy to hear if either of those things have changed recently, it's been a little while since I looked into it. The only reason I don't use AOSP ROMs right now is because of the RIL issue, I need my phone to work as a phone first and foremost and that means going with something based on stock Samsung software. Of course, if neither of those things bother you, use what you like.
Hmm, weird. I have no call issues, and am getting 20MB/10MB on 4G LTE for data speeds, same as I did on my Nexus running AOKP build 6 (Android 4.2.2). Even the number of bars is the same, and more bars near my office than before with my Nexus (may be due to better radio hardware though). Also, I tested audio on video recording, and hear no difference in the videos I took on my Nexus. I also have kids, and the test I did was whispering to full talking from 5ft away - hear everything.
Weird. Guess I'll just keep using it since it's working for me.

Different strokes for different folks. Personally I like many of the features of Touchwiz (The samsung camera app among others) but hate the way it looks so I use beans 4.1.2 builds. I was on AOSP 4.2.2 for a while but had isseus with the gps not tracking my runs properly and the low recording volume really got to me.
I've found that most AOSP builds leave me wanting. AOKP has never disappointed me; across devices.
If you had good reception with the Nexus...well, that speaks volumes. You're not anywhere near a fringe area. If you have great 4g, the Nexus worked great and AOSP roms on GS3 work great.
Where I live, there are a bunch of fringe areas and a lot of handshaking between 4g and 3g. The Nexus....I had to return it immediately. TERRIBLE reception. The GS3 with AOSP was a little better...but not much. When I'm sitting beside my wife with a rooted GS3 running Cleanrom, and I'm running CM10.1 and I have no signal and she has 4g...well, it gets frustrating. lol.
But I'm glad it's working for you...wish I could run 4.2.2...stupid RIL.
For those having GPS problems, have you done this?: http://forum.xda-developers.com/showthread.php?t=2201668
I much prefer the pure Google experience. when I had an HTC I hated Sense. When I had a Motorola I hated Motoblur. I didn't see any reason to learn to like TouchWiz
Also, I think I am blessed with my geographical area. I can travel 45 minutes from one side of my home city to the other and still have 4-5 bars on LTE.

[Q] Signal Strength MD3 Updated - Possible Fix

Possible fix. jmxc23 got me thinking. Why does Moar 4 have a good signal and Moar 5 does not? So I compared the two roms, Moar 5 is MD3 and 4 is MB1. Actually all of the MD3 roms gave me a Bad Signal. I did some comparison and found the following files in the rom that were not part of MB1. I deleted them and zipped up and reinstalled and got my signal back, but only better than before. Anyone willing to give it shot to confirm or debunk. There are also two different files in Framework, but won't boot without them, so they are not included in this zip. I also deleted two lines in the build property that says required by Verizon. If they say it is required, I question it, probably a control thing. Unzip the attached and remove the files found in this zip from Moar 5, except build.prop, you can replace it with the one in the zip or edit it yourself. I now have 3-4 bars instead of 1-2. Now Moar 5 works for me.

I wish somebody could figure out what verizon changed with the md3 update that killed the signal strength for me. I have pretty much tried all the different roms that use md3 as the base, different kernels, modems and nothing seems to help. I lose approximately 10 - 15 deb on md3 meaning it goes from the high 80's sometimes higher but up to 111 or more dbm on md3. Something in the rom has got to be blocking the signal, maybe the build properties? I live in an extended network coverage area, so those of you that live in a strong signal area, may not see the difference.
On md3, lose signal, garbled voice, so it's not just the signal strength meter.
We don't know as Verizon pulled the update so that they can fix the problem.

That is why I asked the question, I knew that, but all the developers seem to want to jump to it anyway, runs fast, but signal not so good in weak signal areas.

If that was the case then why only 3-4 ROMS are based on MD3? If developers were that eager like you said then more MD3 based ROMS would released by now. It seems to me that the developers are looking for a temporary solution or waiting for Verizon to fix the problem. Also those that already have a MD3 based ROM basically using the previous modem. They might also be working on a temporary fix.
I've tried previous modems, kernels,still bad. It is almost like verizon added something in to gain more control and by doing so crippled the signal. I have noticed additional contols in the build property like wait times. The same code could be hidden elsewhere in the rom too. I don't have this problem on the ported md4 version from sprint. That rom has moved on to md3 and same signal problem. I feel that the develipers here are likely to find the problem before verizon does.

I am using MOAR ROM so I haven't gotten those problems.
I am also running moar 4.02 not version 5. Version 5, I tried and same issue. I think it is more noticed in weak signal areas only. Where I normally get 2-3 bars, I get 1 and dbm is a lot higher. I am also on a new phone.

It is always like that with weak signal areas regardless of ROM. Switching modems will either work or it won't. A network extender helps so does improving cell coverage in weak areas those are your only two options at this point.
Good hear you found a possible solution. To remind others try this only in weak signal areas.
No worries moar is going back to mb1 for better signal and thank you op for helping to make moar all it can be
