[Q] Arizona - Signal Issue - Normal or Not? Thx - Verizon Samsung Galaxy S III

Hello!!
Thanks everyone for stopping in.
so I have had my S3 since Black Friday .. 97 cents at Sams Club.. Woot
Ever since I purchases my phone I have yet pass 3 Bars for reception. Is this normal? I live in Arizona so I'm not sure if this is an issue I should worry about or if it is just normal.
Is there any way to figure out if my phone is defective? or has reception issues?
I did a speed test and
have gotten around 4500>7600dwn / 2000->3000up
I have Rooted/Unlocked and flashed a couple of different roms and So far am using a Root66 Rom. ..
I dont really use my phone as a phone all that often but so far haven't noticed any dropped calls or download stalls.
any Advice?
thanks everyone.
I have a Signal Strength of -103dBm 35asu..

I am also in Phoenix and I was thinking the same thing, what modem are you using? I have just resorted to 3G and even then I haven't seen more then 3 bars. I'm on cleanrom 4.5 with stock kernel.

Im in West Phoenix and I do see low signal in my house (usually 1-3 bars with 2 being the norm). But out and about I get 4-5 bars 90% of the time when I am driving. I see normally about 14/4 on 4g and 1/1 on 3g at my house and usually 25/10 in Buckeye when I am there. Even with 1 bar in my house i have yet dropped a call. I find that the HE modem works best for me so I rock that with a K3 base.

not really sure on what modem I am using.
As Far as I know everything should be stock 4.1.1 from Root66's rom.
I am just hearing all these discussions with signal issues with the s3
the only thing i can really do to troubleshoot it is go down to the verizon store and see if they have a phone on a network I can test against.
If they get better signal on their phone.. then I would have to assume my phone is jacked.
troubleshooting these issues is difficult without a base to compare our statistics too.
currently I am in Apache Junction and 4g signal is abysmal .. 515dwn 1000up
..
but its apache junction.. so blah.

Ya It probably spotty on the east side I havent been over there in a while so I cant comment on how my phone is over there. If you are running a stock rooted K3 image then you are gonna be on the K3 radio which is the most current. You can flash another radio in your recovery from here and see if it helps.

I live on the east side (not as far as aj) and I get great signal. Full bars everywhere I go and 35-40 down 10-20 up. I would agree with going into a store and comparing side by side.

Edit: Stupid auto signature, I've got an s3 as well.

Signal sucks in apache junction. Lol. I used to stay out there. My little bro is there now with his Razr and he keeps complaining to me about signal.
I bet you get full bars in South Scottsdale/North Phoenix.

ATT's network...

Has anyone had a problem today where your phone just cannot connect to ATT's 3G or HSPA network? For some reason, my phone is getting little-to-no signal, and if I do, it is only on GPRS... I CWM'd to my stable nandroid, but no dice, leading me to think that this problem is with the network.
What's XDA's thought on this? Possible dev issue?

Their network is just pretty terrible right now. However, by summer we'll probably be singing a different tune about ATT's coverage when the iPhone user population will even out a bit. Also, I believe ATT threw down a few billion for network upgrades this year. It seems like they really took that Consumer Reports article to heart, so I actually see good things in the future.
i haven't had 3G in 24+ hours in NJ. stock, non-rooted.

interesting.. i spent a few hours yesterday with my phone going in and out with GPRS and no network connection at all. i've had fairly consistent EDGE ever since. i normally see 5 bars of 3G at my current location (newark, NJ).
reboots and battery pulls seem to have no effect.

No AT&T 3G here...but I use edge network, get mostly 3 to 5 bars mostly indoors or outdoors depending on location. At my work, it's pretty good signal and get around 150-180kbps speed but at home is slower which is around 100-125kbps or slower, probably. I usually use wifi at my home with my own internet.
Out of Davenport, IA and I have great HSDPA signal running Perception 10.1 with the included 2.6.32.9 Firebird Kernel. I have flashed a bunch of DGs ROMs and never had issues with connectivity (voice or data).
I also get that the sim card.has been removed and its pissing me off.... btw, im on phoenix 3.5 with a setiron 1.5.6

Las Vegas + ATT = terrible.
I just went on a 2 say trip there, took me 2 hours to download a 37kb attachment with full bars. I'd get 30 text messages at once an hour late, with full bars.
If I had to work on the strip I'd drop att in a heartbeat... that is totally unfunctional!!

My definition of normal is >3Mbps down, >1.5Mbps up... How is yours so different when you are so near? I get these speeds regardless if I'm on HSUPA or UMTS. I tend to use the latter to save battery.
The more I look, the more I think that ATT just capped my speeds 2 nights ago. This is crap. No modem change, nothing fixes it.

From what I'm reading on various threads, it seems to be varying as to who has good reception and who doesn't. My S3 gets better reception than my HTC Dinc did.
Man I hate when this happens. I think you should keep asking around. I don't think your question will be answered here. Keep searching. Maybe installing other radio versions on your device is the answer, if you are into tinkering.
I feel your pain. Coming from a bionic which had phenomenal signal my sgs3 is meh meh meh. But I still love it!

signal quality seems to vary a lot on our GS3's.. many people complain about worse signal while others have decent signal. personally, my signal is pretty similar to what I got on my old Thunderbolt.
I was getting terrible signal at my house as well. I called on Sunday and asked if there was an update or something to correct the problem. I was issued a new SIM card and it came today. 2 hours in and I have only had data flicker once and ot used to happen every 5-10 minutes. It doesnt hirt to make the call.
Switched out the sim today still crap signal at the house. I'm not gonna be living here much longer I get strong data signal at the house but voice sucks. I'm moving soon or I'd say I would buy a signal booster for the house

I get one bar inside my house. If it ends up switching to 3G (which is rare), i get full bars. The moment I go outside, I get full bars on 4G.
We have two phones and they are about the same, so I don't think switching them will help. The 3G is better than I got on my old DINC.
I do hope there will be a software update to kick it up a notch, but I'm not hating it. I really am not having issues anywhere else but home and one day I had to run into Walmart and got no reception, but I normally don't go there, so I couldn't care less. Oddly, when I was in Target across the street, I had full 4G reception. :shrug:

One thing I have noticed is that the bars shown on the notification bar, and what it ACTUALLY is getting differ sometimes. It it like there is a dealy, and a strange averaging algorithm.
Unfortunately I have a similar issue. Admittedly I don't live in the greatest spot for cellular signal but it seems the S3's radio is "weaker" in my situation than my HTC Desire and my Droid MX2. The MX2 seems to rule them all (and I've always read the one thing Motorola does well is radios). Normally the Desire and MX2 will read 5-10 dB better than the S3, and voice quality tends to be way better with either and I rarely drop calls. I haven't tried any other radio / modem, right now I am on VRLG1 (which is what the phone came with), maybe I will try going back to VRLF2 to see if it makes any difference.

Those with signal issues

I was having signal issues in areas with less then 3 bars for the most part. Sometimes I would randomly lose service for a few seconds here and there. My calls where dropped or the caller would cut in and out during the conversation. If your having similar issues then your phone is most likely defective.
I just got a refurbished SGS3 from Verizon and the radio works flawless compared to my VRALF2 purchased in July. I would suggest calling Verizon and complaining if your having similar problems because my phone was defective.
Software problems
Not sure how you can conclude it was your phone. Unless you tried the new radio on your old phone before swapping. Otherwise you are comparing apples to oranges.

No actually Hardware problem, most likely the radio itself.

Ive been around the block here at xda so i know phone software and flashing. Software wise I tried it all.
I'm glad these radio issues haven't plagued the vzw sgs3 like they have the vzw gnex. Getting my S3 tomorrow. Hoping I get a good one, but my chances are way better with this phone than doing the refurb constant receive and send back like my g/f's Gnex. She went through 3 with radio issues before we got a good one.

I'm guessing it just a quality control issue. My girlfriend has the Moto Razor which has an great radio in it and she never had signal issues. I was beginning to think that the radio in the GS3 was just terrible. After some time with this new phone its right on par with the razor as far as call quality. Her razor still has the slight edge when it comes to signal strength.
Moto will always have the edge for the forseeable future on radio quality/reception. (notwithstanding the bionic....lol (but that was software IMHO)).
My razr's always had a better signal than any Sammy phone I've had. My HTC radios have always been pretty good also. Lets face it, Samsung's radios are their weakest link IMHO.

I'm new here, so first of all: Hi Guys!!!
I got some Issues with the radio, too. So I tried some different baseband versions with nearly no result
I currently use the LH1 baseband. Since some days I own 2 SIM's from 2 different Providers (Vodafone & T-Mobile).
Unfortunatly I only have an old Nokia N97 for Comparsion, but that doesnt matter atm.
What I've tried to figure out was, whats the source for this Issue - the phone, the provider or the baseband.
Well, I tried both SIM's in both devices and tried a few basebands for the SGS3, with the result that I got a little better Signal with Vodafone SIM and LH1-basband, than with the same baseband and T-Mobile SIM.
T-Mobile: about -105dBm
Vodafone: about -95dBm
The Signal-Strengh on the N97 is nearly identic with both SIM's.
So my final result is:
Baseband on the SGS3 sucks but can be changed to may get some better signal strengh specific for each provider!
Lets wait what official JB will change.
I just got my galaxy and where i live its a really hard to get signal area, but i have own the rezound , regular razr n maxx , galaxy nexus , and the lg and all get good service just tried this galaxy where i live at and lost 2 drop calls and text messages come as errors and thats in stock within.

Its probably a little early to tell. I had my phone for 30 days before i ruled out everything but the phone itself. But I had those exact problems with mine as well.
Things that i checked for right away.

Different modem software ( I tried all 3)

I am on my forth Galaxy S3 for call and data dropping. I use my phone mostly at the same 2 locations, work and home and my data drops constantly on all 4 phones. I have had the sim replaced twice. I have 4 lines on my account one of which is a Droid Razr which was handed down to my girlfriend. I can't recall ever having a dropped call or data with that phone. We were in the Vons grocery store Sunday and we both wanted to d/l the Vons app. It took her less than a minutes on the Razr. It took me almost 19 min and the app is less than 2mb. My phone is still stock. Its a beautiful phone but I'm really starting to hate it.
Maybe I spoke too soon about radios not plaguing this phone. LOL.
Get mine today. I'll have an iphone 4s and gnex to compare dBm and asu numbers. (Scratch that....can't find that info on the iphone (g/f's phone)) (found how to do it....not messing with it while she's using it)
Right now my Gnex is at -87 dBm and 53 asu and I am in a very strong 4G area.
Yeah im having dropped call issues then the phone says lost service and then no sim card detected then new sim card detected and then it gets signal back. The messages the phone displays are not exactly what i stated but similar. I talked to some vzw rep on the phone and she said that i am on the edge of the 4g service area. And that 4g is fairly new where I live. Should that affect my calls though?
Btw i had a htc incredible 1 and it never gave me those issues...i feel as though the speakers were better on the incredible too.

Just keep calling back. Tell them you stayed at a friends house that has great 4G service for a few days or something similar. They gave me the same excuses. What helped me is that there are two other people in the house on the same plan that have 4G phones and they haven't dropped any calls. You have to be persistent and almost demand what you want sometimes but do it as nice and respectful as possible.
well i'll post the other side of this....I had horrible signal issues, tried replacing SIM, no luck. got new phone sent out, same problem. Coming form galaxy nexus with no probs. Calls drop, drop only parts of audio then come back etc. I am in the same places I have been for the past 6 or so years and never had problems until this phone. Can't get signal in my basement or my office, neither of which haev been a problem in the past. so if a new phone fixed it for you, consider yourself lucky.
btw what is a good signal in terms of dbm? in between work/home mine stays in between -90 to -120
I have had my SGIII for a few weeks now and also notice a lack of 4G strength, and I am in NYC. I am coming from the Droid Charge. I am holding off on doing anything until the JB update, if it comes within a reasonable amount of time...i.e. within the next month or so.
Basically, ALL Saumsung radios suck.
My old Rezound has a MUCH MUCH better radio than either my G3 or my Wife's Droid Charge.
I am talking about actual use, not how many signal bars are showing etc....

hmmm...my issue with the Charge was not so much the 'top-end speed' of the radio, which was really good when in a good area, but rather the 'glitchiness or bugginess' when switching network areas, or with certain applications. For instance, I commute on the train to NYC every day from a dominant 3G area. When the train would switch into the 4G covered area, the radio would not automatically switch over to 4G until I would either do the airplane mode trick (which worked most of the time), or I would outright have to reboot. For the rare times it WOULD switch over automatically, the speed would be terrible until I airplaned or rebooted it as above...I am sure as hell hoping I don't have these issues with the SGIII...

VRBLI5

Not recommended to flash the modem unless you are in a good 4G area. I clean flashed AOKP M1 ROM flashed VRBLI5 modem . While in good 4G area had no problems as soon as I left (I am a truck driver) my signal and data started acting up. No data or 1x data signal also cell signal very week and a few dropped calls. So I flashed the VRLAHE modem now I got 3G back signal also better.
I think that VRBLI5 is optimized for 4G but this is just my experience.

Playing Devil's advocate here, could the bad signal just have been a really crappy area? I'm in the northeast and I know parts of Maine I fluctuate considerably and lose signal all together. Other phones do the same so I know it's not my S3.

Not really as soon as I flashed "HE" modem signal and data returned to normal. As I said I'm a truck driver and in the past year and a half since I got my first android phone there were only 4 or 5 occasions my 3G dropped to 1x and that was only in PA and WV in the mountains. Where I was now in IL on an interstate it should not have happened. VZW has the whole USA covered with 3G. A couple months ago I was driving through WY not a town in a 80mile radius and still had 3G.

I usually stay on 3g until I step out of my house or until I go to town. I haven't noticed a difference thus far in my area. I was also in a extremely strong 4g area when I flashed and it changed to 3g without a problem and has the same service I have always had. I'm personally running Paranoid android 2.52.

That's kinda messed up about your trip thru WY, the parts Maine that don't have any coverage from Verizon have plenty of towns lol.
well i hate to be that guy but i.think your issue is on your end
... lastnight the club where i shoot trap has no lte. my device usually will drop data there. this is the first time i had solid 3g and it even switched down to 1x but data never dropped! also lte signal seems improved aswell. imo this is the best radio to date.
this radio has been an improvement for me. in my office i am lucky to get 3g. this new radio has given me a steady 3g signal all day so far
New radio is working fine for me as well.

Just wanted to add my experience as well. After 24 hours using this radio, I can say that signal is much improved on 1x with data off and LTE had never been this fast for me. Pulled 48 down 20 up this morning here in Hollywood.

On the official release of Miui which has had many reports of data issues. Flashed new radio yesterday, I am in a fringe 4g area, and the handoffs from 3g to 4g seem to be much better for me. Previously after moving into a 3g area, I would have to go into airplane mode in order to get 4g back, now it seems to be switching on its own.
I wish someone would explain the whole rpm thing. Does it need flashed with the modem? Does it need flashed everytime we change the Rom? Do we even bother flashing it if we are not on the stock Rom? Why has there never been an rpm zip with every other modem?

ok now bear with me...lol I have been extensively doing some research on this topic. It seems RPM has to do with power management for the radio. This was implemented on the G7 update. I had no clue because I never take OTA's...In order to see the signal improvements the rpm file should be flashed with the latest radios. However nothing negative will occur by not flashing the RPM.zip. I believe this was an attempt to help fix ril issues with data handoffs and spotty 3g signal.
So if you flash just the I5 radio and dont notice any improvements or even worse signal try flashing the rpm.zip and I can about gurantee an improvement will be noticed. I can not believe how much better the 3g to 1x signal and data handoff has improved!! Anybody is more than welcome to chime in and correct me if this is incorrect. There is not much info on this topic as I spent a couple hrs putting bits of information together to come up with this conclusion...hope it helps!
I flashed this new modem/radio,and frankly, I see 4g on my phone more now than I did with the G1 that was on it previously. Everything else works as good, possibly better than before, though I did not take any measurements before flashing.

MF1 Good Suddenly?

When I flashed MF1 when it first came out I noticed I was getting worse signal and slower 4G speeds and no 4G at all in my house. Download speeds would be about 4-6 mbps down. Now, all of the sudden I am getting a strong signal and now get 3 bars of 4G in my house with download speeds upwards of 20-21 mbps. I have not changed ROMs or kernels. Over the last week I'd say I noticed this. I wonder if Verizon did anything on their end. I am in NJ about 20-25 minutes west of the Lincoln Tunnel off of Route 3. Anyone else over the last week get a sudden jump in their signal strength and speeds?
That's what people call "settling in" a phenomenon (as far as I know) that means that software (generally stuff like ROMS, kernels, modems) will sometimes become more stable and overall better with time, with no change to the software

Or maybe they put in a new or upgraded cell tower near your home or city that could explain it.

I get what you're saying but I never experienced a "burn in" with any other modem. I'm not complaining at all lol I just wanted to point it out.

Funny story...my town recently shot down an attempt to construct a tower. That thought they were going to get cancer being so close to a cell tower. Maybe a neighboring town said ok.

Actually I believe this has to do with the S4 Google Edition RIL blogs that were merged on 7/1. Since the 7/1 build I have found reception to have improved on my S3 as well, getting an extra bar in several places around the city.

I am on a touchwiz ROM. BoneStock 3.0 to be exact.
U guys and girls who have had a great experience with mf1 are lucky. I've had terrible coverage since the last 2 updates dropped. I'm battling it out with vzw now. I had to flash back to a stock tar from way back and go through 4 updates....just to prepare for this worthless battle of wits with vzw. However the good news is the rep accidently told me about another update samsung is going to roll out to address spotty coverage.....so this beers to a queationable leak!

The update he spoke of will be found in CM and most other AOSP Roms that decide to include it. Check your individual AOSP based Rom for details.
