[Q] LTE Signal improvements with 4.0.4? - Samsung Galaxy Nexus

LTE just when live in my town on Monday at for the past two days the bars fluctuated from 1-4 frequently when the phone was in the same location. Today I flashed AOKP B29 and have noticed my phone holding onto 4 bars without any drops all day even when I move around the office. Does this have to do with 4.0.4 or the fact they are probably still in the testing phase since it hasn't been officially announced

Ignore the bars, they're meaningless between OS versions. They can program the phone to give full bars in crappy signal, which is kind of what they did here, basically. You get more bars for the same level of signal. So you're not imagining things.
However, try not to use bars here. It's just not helpful, generally. Go into settings>about phone>status and give us the dbm readings from signal strength (you can ignore ASU, it's basically the same thing as dbm). That's far more relevant.

-92 dbm is what its showing right now. Doesn't seem to be moving from that number.
Now -88 is showing 2 bars

Does build 29 include new radios?

[Q] Time Without Signal Inaccurate?

I'm not sure what other people have experienced, but I'm finding that my "Time Without Signal" % shown in the battery life breakdown seems to be wildly inaccurate.
To give some context, I sat with my phone in my hand and watched it sitting at "0 bars". I'm using quotes because while it was at 0 bars, it was a -109db signal. I confirmed I still had connectivity by placing a phone call to myself from my desk phone while monitoring the signal db strength. The call came through just fine, and without any delay either.
However, after refreshing the battery life screen, the Time Without Signal % had gone up directly related to the time it sat at 0 bars.
Yes, 0 bars is a pretty bad signal and a reality I've had to accept ever since I moved offices but it doesn't translate to no signal. There is a difference between the two, that's for sure.
Now, perhaps this is ROM-related? I am running bigxie's AOSP ROM, v5. (http://forum.xda-developers.com/showthread.php?t=1399238)
I'm also running franco's v7 kernel.
Anyone else with similar experiences?
Can you surf the web while at 0 bars? The 0 bars may be related to network bars and not cell signal.

Haven't tried that yet, but it does show a data connection existing. I'll give it a try after lunch but regardless, doesn't that leave Time Without Signal as a relatively subjective measurement?
I was able to confirm that the data connection still works with 0 bars...
This is the case with other Samsung phones that I've owned. I've found that Samsung's reception quality is quite similar to Motorola's, but Samsung phones seem to be conservative when displaying signal bars.
I can confirm the same behaviour. Something isn't right.

[Q] Low signal vs other phones

Hey guys had a question for ya, since I'm new to Big Red I'm not sure if this is something normal or what. I have 2 iPhone 4's and 2 Incredible....I get full bars on my I phone's but only 1-2 on my Incredible. Normal behavior for Android?

It may just be the way they are programed to show bars. You shouldnt measure by bars but by dbm. Both phones could be at -89dbm but one os could be programed to show -89dbm as 2 bars and the other os as 3 bars. To see the dbm's on the inc go to Menu - Settings - About Phone - Network. On an IPhone im not sure where it shows dbm, but im sure its there somewhere. FYI the lower the dbm number the better the signal (89 is better than 99).
Could also be that the IPhones radio antenna can pull a stronger signal than the inc, seeing as it is newer it may be a better hardware thing.
Two bars is showing -72. Guess its just the way its showing the bars
My iPhone is showing the same in field test mode
Yeah there's no standard for what signal strength should be what amount of bars, so some companies have different values. HTC phones tend to have low bars with good signal. Sometimes I'll get 0 bars but I can perfectly watch netflix or talk on the phone with 0 breakups.

[Q] Why do I have terrible phone signal but constant 3G/4G?

I work in downtown Houston and, while I am always connected to either 3G or 4G, I consistently have terrible phone signal. It'll only ever range from zero to 3 bars and I don't even think I've seen a full signal since I've owned this phone. Now, this isn't too much of a deal as I can always text and make calls (although it takes a while to connect sometimes.), but I'm left wondering if this is a cell tower issue or if something may have updated incorrectly. I'm rooted and unlocked and have only ever flashed the last 6 or so Lifeless ROM updates, so I don't really think I could have messed it up myself, but I find it hard to believe that downtown Houston would have such bad phone signal. Any insight?

I work in Downtown Denver and have a very similar problem downtown, but not out in the suburbs. My Sprint store has given me a couple of explanations.
1) The buildings block the signal. There are areas of downtown, particularly by the tallest buildings, where occasionally I will drop my cell signal completely
2) In a higher concentration area signal is reduced due to more people using that signal (I don't understand how this one affects signal strength, but that's what I was told)
How is your signal outside of the downtown area? Did you update Profile and PRL after flashing? Ever dropped the phone?

Well, I live about 14 miles west of downtown, and even there, I don't get full strength signal. As I said, I don't ever remember seeing more than 3 bars of signal. I update the PRL and Profile after every flash, and just today I dialled ##72786# to see if the hands free activation would do anything but no luck. I've also encountered moments where I'll be at home (again, I normally have data coverage and a few signal bars) and suddenly, I'll get an alert notifying me that I'm roaming.

That happened to me the other day. I was at work and I got roaming pop up. Really weird since that never happened before and because my 4G is so strong. 36168kbps Down and 6304kbps up.

This has been an issue on every LG Sprint phone with Android I have used. I am not sure what causes it but the bars on the screen never show full strength. That doesn't mean it isn't working though. I have heard it is just how LG worked the rom to show signal.

Let me first start off by saying this is the furthest from the truth. If it shows a weak signal its because this phone has a weak signal.
This is my 3rd day with this phone and as much as I raved about it on a couple of threads, weak signal is definitely one of the negatives.

How can it have weak signal if when I get this I am getting 36168kbps Down and 6304kbps up?

Dude the LTE radio has nothing to do with the phone signal. Two separate radios.
This phone just has weak radios. Now the question is, is it a software or hardware issue? my bet is software but then again I'm not an engineer
Edit
Funny thing is open signal maps gives me an 85dbm reading yet in settings it shows 94 dbm

I just discovered if you switch the network setting from LTE/CDMA to CDMA my signal bar gets full.

I don't have an issue with 3g I get great 3g signal my issue is with lte. Lte has bed in my area since late August early September and I've had the s3 evo lte and the iPhone none of them have had an issue picking up or holding lte the lgog does.and I think it all boils down to the phone not recognizing the correct signal and thinking its weaker than it truly is. In my house and through my town I would never drop lte On the others this phone barely holds it. I've been 100 yards from a cell tower and the phone won't go below 84dbm when I know the signal strength is stronger
I installed the Network Signal Info app on several phones in my store and the LGOG registered about 9db worse consistently compared to the SGS3 or Evo LTE
About the same thing I've seen with this phone I'm hoping its a quick fix for lg with the next update. I was really hoping that zv9 would come with a new radio

Getting Verizon to address signal issues?

Has anyone had luck getting signal issues addressed with Verizon?
My signal has gone to crap - I thought it was my new One M7, but my wife's S4 is exhibiting the same behavior...can't help but think something is wrong, as I used to get a solid 4G signal at home a few months ago on my ReZound.
I live just off a major state highway, I am in town, and right in the middle of the 4G coverage for Verizon (there's 6 towers within 4 miles of my house, and 17 antennas - according to antennasearch.com). The local Verizon tech pulled their map and said I should be getting full signal at my house.
Despite all this, when I get within a mile from my house coming in fr the East on the state hwy, I drop to 1 bar of 3G and lose all data. At home, I switch between these signals:
(rare) 4G RSRP -120 to -123 dBm
3G (eHRPD) -110 to -118 dBm
1 1xRTT -97 dBm
If I go another half mile west in town (which is flat land), I am back to sub -100 signal on 4G. Any way to get someone to actually investigate and do something about it?
Thanks...
Call tech support and demand that they send a tech to investigate. I have to do it constantly. They tell me every time I call everything is fine on their end and a few days later it gets better all of a sudden. It's like they don't want you to know they have an issue.
You on the latest radios? I noticed when I updated to the latest radios my signal improved. Still would call tech support and have them check what's going on. Don't take we have no issues as you live in the area and they don't. So they should take your word for it. If you know others in your area have them call to so they have to take it seriously.

Man, I have tried newest radios, older radios, combinations of different setups with different ROMs (Sense and AOSP based), flashed RUU and did factory resets, back to stock rooted with new and old radios, and even a new SIM card...now back to 100% stock and fully updated - getting ready to see if they will trade out my hardware in case mine is bad.
One odd thing - when I first got the phone, the Best Buy tech couldn't get the SIM to activate, and had to call Verizon. When I swapped my SIM out two weeks ago at the local Verizon corporate store, they couldn't get the new SIM to activate and had to go to the back and do it from the computer...which is what makes me wonder if my hardware is bad.
Have had Verizon here (same house) for 8 years...very rarely had a dropped call in that time up until about 2 months ago (when I got my One M7). I drop about 1 out of every 3 calls now, and the other two get garbled sometime during the call - I hear "you're breaking up" at least once per call.
Your wife has a totally different phone and she is having issues as well so she has hardware issues too?
Her Samsungs always had worse reception than my ReZound (why she likes them, I have no idea) - but I chalked it up to bad reception on the device line.
I never looked into her signal strength until I was comparing my One to hers, which is when I noticed her signal is also bad (mine is worse at times). That's what made me wonder if it was something Verizon should look into in the area.
The hardware thought on my end is due to the fact that I can't find a combination of radio/ROM/RUU that will improve my signal at home and the fact that both SIMs had an issue activating in the phone. Grasping at straws on the hardware thing really.
May reactivate my ReZound tomorrow to see if the signal has just gone to crap here or if it's my phone.
I had signal issues at one point and the problem was because the SIM couldn't seat all the way because of a tiny piece of plastic still attached to the back side of the SIM. It made just a tiny little bump that made it so the tray wouldn't slide all the way in. Since then though the problem in my area has been Verizon. Every time I've called to tell them the coverage here has been crap they tell me the same old it isn't their fault junk. Keep hounding them and they will send a tech even if they tell you otherwise. Like I mentioned before. They almost never admit to an issue with a tower. The only time I have heard of them admitting it was when it was bad enough that they received several reports.
Update:
I reactivated my ReZound yesterday morning to see if my recollection of signal was off or if things are worse on the network near my house.
I monitored it heavily yesterday, last night, and again this morning, and at home the ReZound keeps a 4G signal ranging from -110 to -120.
I did a side-by-side comparison with the wife's Samsung, and while the One mirrors the Samsung (when one drops to 3G or 1X, the other is doing the same), the ReZound held the 4G signal. I watched the Samsung go from poor 3G to 1X - ReZound held 4G.
Also, the dreaded 1 mile dead zone around my house - on my One, Slacker quits playing about a mile from home, says it has lost connection to the server, even though I am on a decent 3G signal. Twice yesterday (coming and going), the ReZound held 4G through the zone and Slacker never skipped a beat.
Conclusion - either something is wrong with the One (and possibly the Samsung?), or the One simply can't contend with a weak signal as well as the ReZound.
If a rep said you should have full bars they might not have the antenna aligned right. I remember years ago someone on one of the sites talked about the same problem he was suppose to have full signal but want and Verizon sent someone out to check alignment and found the person who installed it didn't have it aligned right. After he rest the antenna the guy had full bars. I'd bet this happens quite often and maybe have the two that told you to have someone sent out to see if the antennas are setup right

With newer phones, they may be dropping the 4G and 3G signal because it is below the preset threshold in the firmware. -110 to -120 is horrible. You should be getting higher than that, like -90 and up.
Edit: if Verizon is saying you should be getting full bars, your signal should be above -78dBm. (Signal is measured in negatives, so "above" -78 is 77, 76, etc). If you read any documentation on signal strengths, you will see anything below -105 is so horrible of a signal, most data, sms, and calls are frequently dropped. With you claiming with the Rezound having not experiencing this, it is highly likely what the above poster is saying is true: antenna alignment is messed up. Even a fraction of a degree will mess with signal quality.

[Q] Signal bars stay full on LTE. Stock OB6

I have the N900T, stock OB6 , unrooted, sim unlocked and on the cricket network. The LTE signal always reads full signal at the top of the screen. If it switches to HSPA+ it will read 4G and the signal will fluctuate like it should and appears to be accurate. While on LTE I am also getting slow speeds, but it is sporadic. I am supposed to get 8Mbps down and around 5Mbps up. I am not even close to that most of the time, although sometimes I will get those speeds. So this may be a network issue, I will see if this clears up. Has anyone else had an issue with the LTE signal bars being inaccurate?

One thing you can check, is the actual signal levels. In the dialer (phone app), dial *#0011# and take a screenshot. This will show both your signal bars, and the actual signal levels (look for RSRP, RSRQ, and SNR). Do this first in a place where you know for sure that your signal should be full bars, then do it again in places where you believe it likely isn't. This will provide good indication on whether it's an actual signal issue, or you're just hitting towers that may not have the bandwidth available.
