I get 1 to 3 bars of signal in my house (kinda in the country) with my T-Mobile prepaid SIM in an Optimus T... but with this Vibrant, I barely get a signal -- a phone call is nearly impossible. I have tried two different ROMs plus stock and all seem to have this problem... Is this phone (the Vibrant as a whole) that bad, or is my phone possibly bad... any fixes?
Thanks much, Aaron
Any idea? I can sit on my couch and talk/hear just fine on my Optimus T and on my Sprint BB Tour w/ the T-Mobile SIM card in it... 1, 2, 3 bars...
This Vibrant mostly shows no signal.... once and awhile it will show a bar or two but calls rarely go through and when they do the reception is horrible. Do I have a setting issue? Could this phone be defective? I am really at a loss here... I am about to put it on Ebay as I am lost...
Thanks for any advice..
Check out the super build prop tweaks in the dev section. Helps with signal quite a bit.

Hello,
If you have your phones rooted and have cwm (clockwork recovery) or know how to use odin, then I would recommend trying different modems and see which one works best in your area. You can download them here. Let us know if you have any questions.

I rooted it... tried a few different ROMs... and around 3 or 4 modems... none mattered... I will look into the build prop from the previous post though...
nope...
I added the data mods to the build.prop on yet another custom ROM (I had to reroot, etc as I had returned it back to stock after giving up) and it is showing more bars -- but still can't make a call from my couch -- which I can do perfectly well on my Optimus T.... Unless I get another idea on here, I am going to Ebay this Vibrant (I got it for a good price on Craigslist) -- and probably try a Sensation off of craigslist (anyone know if their reception is better?)...
Thanks much everyone!!
I've noticed something similar, just recently with my vibrant around my house I jump between 0 bar (usually around -109 dbm and 1 asu) to full bars (-89 dbm and 9 asu). I've grabbed my wifes MT4G and compared while I have zero bars she will have full bars (usually around -9 dbm and 11 asu). Not sure what's going on but flashed a couple of roms, tired all the modems, and played with build.prob. I guess there are just some spots that are Vibrant dead zones.

dont know what causes it but i have four vibrants, mine wifes and two kids. they are all running current cm7 nightlies, and all perform pretty much the same, but two of them most of the time have edge and two have h quite often, thinking something went a-rye in the factory lol. as far as signal goes ive noticed that even when my wifes has full bars and sometimes mine may have 1 to none, they still seem to make calls the same. strange...sorry best i can do with my limited knowledge, i wish i knew half the stuff these devs know. id probably develop the best rom and also b divorced. good luck
Okay, so I went out and bought a Sensation from Craigslist today and it has the same signal issues... My Optimus T and my Sprint Tour (using GSM) have great signal in my house -- but this Vibrant and Sensation get little or no reception..... I am confused.
The Vibrant has poor wifi with my weak Belkin router (and it is a spendy one too, very frustrating) -- but the Sensation has nice wifi, so I guess I will keep it and use wifi calling cause I love the Sensation -- and I will resell the Vibrant.
Thanks for all the advice ya'll gave me -- or any more that you send my way
/Now to get to rootin' my Sensation, as I am sure I will do soon enough lol...

Let people use it for a while. They haven't even had for more than 12 hours.

Well, technically it shouldn't take more than a few seconds. Put the phones in the same spot, and check the signal strength in dBm.
I agree, those that have it the rest of the world is dying to know!
How is the signal? Is it the same radio that's in the GS3?

Curious to know from those who upgraded from HTC Thunderbolt with frequent LTE disconnects if the issue remains, which points to network issue, or eliminated but it'll probably require at least a week to confirm.
Coming from GNex, plz let it be better then that :fingers-crossed:
I'd like to think it is slightly better because the size of the device means the antenna can be farther from anything that will cause noise or something. Guess we'll find out tomorrow.

I really hope it's got a better radio than the GNex. I've been limping along with that thing for the last year. I'll go from a 20 megabit connection to no data without even moving locations.
I kind of hated ordering the Note2 blind, but I've been waiting for a note to arrive on verizon since the note1 came out. If the radio is lousy, well at least I can draw with it.

another curious verizon customer. Been on htc devices since joining verizon and samsung's cdma woes are well documented. I want the note 2, but need reception.

Much better than the GS3 I had, even when I was using all the different types of radios that were available.
Data connection is faster too. Most likely as a result of NOT using a piece of $hit snapdragon SOC.

I think my rezound has a snapdragon SOC, and it has no problems with reception or data speeds. Get up to 40 down and 15 up on it.
Samsung has a history of bad radios on Verizon. It's really the only potential negative of this device.

great reception. i also think this has to do with no only better hardware but more landscape inside the phone offers better attenna replacement.
over all phone is awesome, im having no issue one handing it

Well I upgraded to the DNA and I haven't had a single data drop, unlike my Thunderbolt which had them several times a day.

cool, going to head over to verizon store and play with it and dna and look at signal strengths. I only get 1-2 bars in the hospital so if its worse, I might not have signal.
The rezound had good 4g reception but average 3g reception; the galaxy s3 had good 4g reception and below average 3g reception. Anyways I hope folks provide good feedback and 4g, 3g and cellular reception for the note. Very interested in this phone (though it is bigger than I would like). To be honest I would go with the DNA if it had a large battery. Don't take me wrong I think the note has a lot of nice unique feature I just wish it was a bit narrower.

i have my galaxy nexus and my note 2 side by side and signal strength is the same with a slight edge to the note 2. I am looking at the signal strength in options and not the bars.
I have notes 2 and DNA side by side at the possibly worst corner in terms of cell signal.
Note 2 is extremely unstable. keep on switching between LTE to 3G to no signal (the round circle with a cross over the center. usual stop sign)
while DNA has a full bars for CALL. and 1x for data. It is slow, but it is stable and usable.
SHAME ON YOU SAMSUNG. Why put such a stupid radio chip on such a good device otherwise.

Only matters when you are in weak signal areas. If you're seeing -70 to -80 DBMS or lower you're in a decent area. What the Gnex couldn't handle was the weaker areas. Where my rezound was -85 or so the Gnex was -100 or worse. I'll post something when I get back to my office. I'll do a compare and post it. If the Note 2 is anything like the Gnex it will end up the same way with me. Returned! I don't care how cool the phone is.

Not what I wanted to hear
Do you have dBm readings that you could post for a comparison? The data switching between 1x, 3G, and 4G could be fixed in an update hopefully.

the dbm on N2 was jumping from -120 to -98 to -75 and the data connection is ON and OFF. That is frustrating.
My location (my cubicle) here now is like a stress test case in terms of cellphone cell strength in a weaker environment.
IN good coverage, everyone is happy. Both phones are -75dbm and stable.
In weaker ones, N2 can't hold on to a data connection.
I really want to love it, but in this checkbox, there is no competition.
It does perform well in battery category tho.
And by the way, refer to your other post, the screen is not brighter than DNA screen. even put to full brightness. It is just so pathetic putting them side by side to compare.
I will continue test until this evening. If the data connection weakness is confirmed, I have to take N2 back to store. I feel it will make my wife crazy to see me carrying both giant 5 inch phones each costing more than 600 USD combining all costs...
Simple question can changing your CID effect you mobile signal? Also if im getting poor signal after flashing the GE 4.3 ROM could it be a radio issue? Like do i need to update the radio or will it not make a difference?
Also ever since flashing this ROM ive noticed poor reception. I have to note i do live in the UK.
Thanks

Compare using actual signal values. Some carriers misrepresent bars to make it look close to fill signal even if actual signal value may not be different.

Are you actually having mobile connection issues when you use the mobile? I've read elsewhere that 4.3 seems to be more conservative with the displayed signal bars, without having negative effects the actual signal strength. So even though it might look worse visually, it actually isn't effecting mobile reception.
I believe the posted 4.3 GE RUU updates the radio to the latest, so you've got it if you've done the GE 4.3 'conversion'. Not sure about the other recovery based 4.3 ROM's though.

Hey all,
I and many other Galaxy Mega owners on this forum have been experiencing issues with poor/spotty signal that in return drains battery life.
This is an issue that is very real. I have tested in different places a Mega next to a Note 2 and an iPhone.
The results shows that while Note 2 and iPhone have full signal strength, the Mega struggles to keep 3 out of 4 bars, and most of the time it stays at 2 bars. I noticed this issue and returned the Mega for a new one, the new one had the same issue.
Someone on here had a theory that it was only a problem that occured with European users, but I dont know why that would be.
Anyway, is there someone out there that could help us noobs out and look into this issue?
I really love the phone, but the spotty signal issue is quite annoying to say the least.
For those of you who share the same issue, please raise your voice.
If you have a serious problem talk to your carrier, it could be a setting or something their end

I dont believe this is a carrier issue. Ive had the same carrier with all my phones, and Mega is the only one with spotty/poor signal strength.
Other threads on this forum are reporting the same issue.
I have the i527m version here in Canada and i have no problems at all with having a low signal as it always is strong and the LTE/4g works awesome..not sure on some other models why this is happening, maybe the moden/radio is forsure different in the i527m version then others, but i am not sure if the signal strength is good all across Canada or not, but i know my area it is good.

I have an AT&T Mega and I have not had this issue at all! I went from a Note 2 and I have the same or better signal strength with the Mega.

Is there any possible solution for this? Like flashing the modem or something? (and in that case, which modem? Im european).
My signal is so much better on the mega..... I used to get on 2meg downloads now I download at the minimum of 8....

Try all the modems, what works for one will not for another.
So like allot of people in here, I sold off my AT&T S5 and scooped up a T-MO S5 for the obvious reasons. What i've noticed is that i get insanely awesome reception everywhere i go with this t-mo phone. At work i would pull down about 3-4 bars of LTE on my ATT S5 and now i get full LTE all day long without the thing fluctuating once. Not a huge difference but still nice to see. This also goes for just about everywhere i go, full bars galore. Anyone else noticing this? Either way it's just another perk along with root and my custom ROM!!:victory:

Bars means nothing. Always check and compare using the dbm menu.:good:
The T-Mobile S5 will show five bars for a -99dbm signal. That in reality should be about 2-3 bars.

It does. It's a fact. When I have a -99dbm signal, my phone shows 5 bars. Then 4 bars with anything below -110dbm. I am assuming T-Mobile did it this way because their LTE is extremely weak, and they want you to think you have a good signal, when you really don't.

dbm alone when talking about LTE is a somewhat artificial number without context . RSSI and RSRP will indicate something more meaningful to the signal quality. -99dbm RSRP would be closer to -79 dbm RSSI and is a strong signal .
I am currently at -95dbm RSRP and am pulling phenomenal results.

Thanks for the heads up, I am on TMO not ATT , but I think I'll still hold off until I see more results. Seems a lot of ppl are having lower download speeds.

I reflashed the ANCH stock Rom and rerooted and am back on the ANCH modem. Got my speeds back up
This is not an isolated case. There are problems with the new Modem. Go to the Development section. Beanstown has a new thread with all the Modems, firmware, and stock roms.. Try different modems, many times they function differently by location.
