I am currently tethering over a 4g connection, and my internet is working fine, BUT I have a complete LOS for the cell signal. I think this could be a very important fact because we should be able to know some things by the fact that WiMax is working while the cell signal is altogether lost.
Hopefully, with this info, a solution is a little closer at hand.
Ok...when people say LOS do they mean Loss Of Service? Or Loss Of Signal?
Because if its the latter, that sht aint that bad. But if its the former...I'm glad I don't have it.

It is bad. People that get it have to reboot phone for it to come back and it kills battery life. Nit to mention missed calls and texts. It is a complete loss of service.

Its 2 separate radios..
I had pandora going over 4g earlier for hours...but lost signal with a crossed out circle after about an hour. Pandora kept going but u couldn't make a phone call, ths.falls in line with the other poster. Im running eg30plus over latest 2.1 midnight.

As WhiteWidows stated, it's 2 different radios. The LOS people have posted over and over about is the ability to make/receive calls (which is what the OP posted about). The Wimax radio (4G) doesn't transmit phone calls. That's why you can do data on 4G and still make a call at the same time.
.....
Hi guys, this is one of my first posts but I've been a long time reader coming from the Evo 4G forums. I'm rooter using Zedomax v3 and experienced multiple LOS as well.
Last night I tried limiting the clock speed to 1ghz and setting the min at 400mhz. Strangly I now get slightly better reception and never had a LOS yet. Will continue to test out this theory and see if it's clock speed related.
I came about testing this since I ran mine at 1.6 for a while and not only would I get more LOS occurances, I would also get phone freezes lol. I tether and stream music a lot so wanted to keep it slightly underclocked to keep the temps down. Hope this helps as a temporary band aid for the LOS bug
It definitely makes sense that the two radios are separate...the point of my post was just to offer some more information to help figure out a fix.
If one radio fails while the other stays working, do we know that the problem is phone-related? Many posters have speculated that the issue may be on Sprint's end, so I wasn't sure if this info did anything to challenge or support that theory. Maybe it does nothing, though -- just throwing it out there!
Someone posted a log cat of a LOS. There's still some coding in the radio files that thinks there is a sim card. Says sim disconnected and result radio off

Hopefully a solution is found soon, I've seen similar issues posted on various android forums. Androidforums, Sprint community and here. Wish I waited a bit to hear more user experiences....

Has anyone tried editing the build prop to manually change the preferred network from wcdma to CDMA auto? Maybe that'd fix that issue
I have been on my current SGS2 stock out of the box for over a week now and have not had any LOS issues, or missing texts, or data not working, or missing phone calls, etc.....
I have been using wi-fi, 4G, 3G, have an Airaive, went to an area where there is no Sprint service and phone roamed fine and then went back to Sprint service when available.
I have been unable to replicate the LOS issue on my current phone through all possible ways of using it.
My first SGS2 was also fine until I rooted it which then gave me an LOS within 12 hours of doing so.
If someone has a another sure way to get an LOS, I am willing to try it on my stock, never rooted phone but I don't think there are any other situations I can try that I haven't already......
Time.I have went 3 days without a los then 2 in same day.It is all random
I tired to search but unsure if I pulled CDMA 100% or not..
None the less, Im going to move over to Verizon and Im after the Nexus. I see people say the signal is bad etc etc. Im coming from the HTC evo and Ive always prety much ran AOSP roms. As we know ( or us Evo users ) the AOSP roms dont show " full " signal. But it shows actual signal. Is this the issue people are ***** about? IS this what they are talking about, in terms of bad radios etc?
AOSP roms show the true signal, but not a masked/boosted signal similar to HTC phones done, right?
The bad radio rumor isnt a bad radio, just the way AOSP roms show the signal... right?
The bar reading was jacked up a notch in 4.0.4 (2 bars of signal in 4.0.1/2 will show up as 3 or even 4), but the db reading in Settings is still correct (though, read issue #2 below). The phone is fine hardware wise. What confuses (or convinces) people are three things:
1) Some people got duds. This will be very obvious because you won't get signal even in areas where other people on VZ can connect. You need to get the phone swapped.
2) The GN has a weird way of reporting signal strength. They completely over-do the hysteresis, so if you test/compare with another phone, you have to keep the GN in one spot for 10-20 seconds before you get the same reading.
3) Software bugs in the baseband which will crash the radio interface and leave you without data for up to a minute. There also appears to be some hand-off issues that may keep you on 3G when you should be on 4G.
The GN has no worse reception than any other Verizon handset, aside from the fixable bugs in the baseband, which really aren't "reception" issues anyway.
So with what you said, all the apparent issues that are there, are fixable in terms of ROMs or official fixes? I like to tinker with my phone, but not to keep it running correctly, ya know?
Is this issue still reported on the current batch of Gnex's?
I just got my Nexus a week ago, but it has worked perfect in terms of signal and data. No dropouts. My radio is whatever it came with, but my ROM is BAMF Paradigm

Personally, I've had fewer issues with the Galaxy Nexus than I did with the Nexus One (that phone DID have bad reception. Great call quality though) or the WinMo phone I had before that. Whenever I have connection issues, I just turn on and off airplane mode and the phone will come back and reconnect to 4G in ~15 seconds. Nothing serious beyond that.
Some people have had more serious issues, and I can't say if it was their phone or the network equipment used in their area or what. Only way to be sure is to try one out. I have little doubt that ~99% of GN users have little/no issue, but the ~1% that do have problems are vocal about them (they should be, this thing isn't cheap).

ROM has nothing to do with signal. Only the baseband matters.

Actually, if they have updated telephony, it can. For example, there are signal improvements in 4.0.4, but you must run the rom and the radios.
That said, Paradigm has made no telephony changes from aosp 4.0.3.

I was really simplifying things since this was a non-technical question. If you go from 4.0.2 to 4.0.3+, you may have more hooks into the kernel and from there into the baseband, but jumping randomly from ROM to ROM isn't the best way to solve a signal problem. Changing the baseband is the best way, kernel the next, and finally the Android version. Basically go in order of distance from the hardware, noting that each level is significantly less likely to cure you.

After reading hundreds of posts on connectivity issues, yours is the first to bring some lucidity and sanity to the hardware issue. Now someone needs to focus on the BS from the carriers and the inadequacy of their distribution systems.
Hey everyone...Yesterday, on my stock, 4.0.4 GNex, I noticed I was getting terrible 3G speeds, and no 4G data whatsoever (even though the 4G signal existed). I thought maybe there was a temporary outage, but no dice...VZW support said there were no issues. Today, the issues still remain, and I have no idea what the problem could be. I took some screen shots, so if anyone could offer some advice, I'd really appreciate it. I'd love to try and resolve this myself instead of bringing it to some of the inept VZW techs at the local store. I'm located in Western NY and there is normally a great 4G signal here.
I can post screenshots once I am allowed since I'm a newbie here.
THANKS!
EDIT: I should add, I've experienced the 4G dropping to 3G for a while, and I know this is an ongoing issue with GNex users, but this is completely different.

Another case, same awnser, considering what you said, the device is running the latest official release, and it seems 4g never works at all: return it and get a new one, probably has a bad radio.
If we can get a NYC vzw user as yourself who doesnt have the issues you're describing, i think that would kill it as faulty hardware.

Meaning the radio just went bad? I've had this since launch day and never experienced a problem until yesterday. Also, I'm far from NYC, so if anyone in Western NY (Rochester/Buffalo area) has the same issue, let me know please.
Well, you said you have a stock phone and it doesn't sound like yourself have made any changes to cause this. So, what is it that you want to do? Flash the radio firmware? Root the phone and try different ROMs? Go through all this so in the end you take it to the store anyway? If your description of the problem is accurate, then it does sound like you have a hardware issue. Just take it in and deal with the inept VZW techs.

No I didn't want to do any of the things you listed. I was asking if anyone here could help me diagnose the problem, in other words, see if there's any way to prove it's a hardware issue. I wasn't sure if there were any applications I could get to run diagnostics checks.

If you never experienced these issues before, yes.
I would eliminate a few things (simcard, check another 4g capable phone, side by side, see if it works fine) first and do some testing.

It ended up being the SIM card. They replaced it, and instantly the 4G worked again.

I know this might not be the best place for network issues but seeing as the TMobile Forums are useless because no one ever answers my questions i thought i'd find out if anyones having similar issues to me. For the past week or so ive noticed that my reception isnt as strong as it used to be like for example at home i used to get full bars now i only get about 2 bars max and the internet speeds are really slow wherever I am..even tho its showing as connected as HSPA. Also sometimes the connection randomly cuts off and then suddenly comes back on again. The phone hasnt been damaged in any way, the only thing ive done to the phone is did an ota update which updated the hboot and radio but then i went back onto arhd 9.7.2.
Hello
My friend who uses an IPhone 4 on T-Mobile lives in Sheffield has noticed the service/signal has deteriorated over the last couple of weeks. Previously she would have full signal everywhere in her house. We wondered if it was because of the current upgrades to 4G that is happening in Sheffield and also London. Maybe that's what's affecting your signal too?

Yep I had a feeling it could be because of the 4G upgrade but I wasnt too sure, if alot of people are experiencing similar issues then that must be the reason for it.

But surely updating the radio is meant to make it better not worse?
I'm on T-Mobile UK and the signal has definitely deteriorated recently (I also live in Sheffield). I've been operating on the assumption that it's because of the 4g/EE happenings.
Now I think about it, it also coincides with me switching from stock to custom ROM.
The change certainly hasn't been of large enough magnitude for me to want to fix it though.
Try a network test app and then post the results. I'll do the same later tonight so we can compare?

I used the speedtest.net app and the first two times i tried the test it failed on me and on the third try i got these results:
Ping: 176ms
Download Speed: 3.41mbps
Upload Speed: 1.65mbps
Which is so weird because its never felt like i've gotten those speeds recently. Maybe I just got lucky and had a decent service at that time because I know later on its gonna go back down to a terrible service..I just hope the 4G upgrade has something to do with this and not my phone.

yes, an update ALWAYS makes it better... especially on something with so many variables, like the radio.
/sigh.
T-Mobile have uncapped speeds now. So no more slow downs, upload has significantly improved.
3G speeds are dependent on signal strength, time, congestion, etc.
Make sure your masts are not being worked on as well as sometimes this can cause downtime.
Hey folks,
Just a quick question I was hoping to get some clarification on:
Like many, I got the 4.2.2 OTA on Tuesday evening and everything went fine with the download and install. That being said, I'm having some signal issues that are a bit strange. For the most part the signal quality is fine. Not really having any connection issues, but I've noticed lower bars being shown overall. After doing some digging though I've determined that apparently 4.2.2 reports signal quality differently than 4.1.1 did... representing a much truer value based on dBm and not overly inflating things for constant 3-4 bars. Essentially it's like I remember way back with 4.0.2. I still find it a little odd that I can show -85dBm and only have 1 bar, but if that's how things are reported in 4.2.2 then so be it.
The thing that's bothering me though is this: at times my signal will read 0dBm 99asu. I'll have zero bars showing, but it will still show 4g in the notification bar and will say connected to the network in status. I can make calls, text, surf the web, download apps, even run speed tests without any problem (although not great numbers, they're not horrific either) Eventually bars and dBm "come back", but the amount of time for that to happen varies. Again, nothing seems to be affected by this, but it's just a little disconcerting to have happen.
So, has anyone else experienced this? Google searches show some talk of it but otherwise haven't turned up much. I've done a battery/SIM pull and that didn't change things. Is it possible something may have gone a bit sideways in the ota download? Was thinking a factory reset may help too but not looking forward to wiping my device only to find out this is pretty normal.
Any help would be greatly appreciated. Thanks in advance.
It's possible that the OTA updated the baseband, please look into that as I'm not entirely sure. If that's the case, then it might just be that the new baseband is not suitable for your coverage area in which case I'd suggest you flash a previous release.

Thanks for the reply. I'll fully admit I'm not as up to snuff on this as others, so please correct me if I'm wrong... but the 4.2.2 OTA did in fact contain new radios from VZW, so shouldn't the baseband have been updated for everyone who took it?
Mine is: I515.10 V.FK01/I515.FK02
As I understand it that breaks down to phone model (I515), HW rev 10, with the new radios being FK01/FK02
Wouldn't every VZW GNex that was on the 4.2.2 OTA have the same baseband; outside of having either HW rev 9 or 10?
Currently I'm locked, stock, not rooted... yeah, probably one of the last Thinking I may unlock and root and try the 4.1.1 radios again. Do I need TWRP or CWM to flash those or can that be done if I keep stock recovery?
As always thanks for all input, much appreciated.
My Gnexus is the same . but despite that it actually performs better oddly enough
Do/can you update roaming (*228) with the Verizon nexus? Or is that just something I could do with my old fascinate (yes, a fascinate and then nexus... I am a glutton for VZW punishment).

You can, but as far as I know you'll then have what is considered a 3G PRL pushed to your phone, something beginning with "5"... if you just let the PRL update and push on it's own like it's supposed to you'll have a 4g PRL, and will begin with a "1" Both work the same and pick up both 3G/4G signals...not sure what the true difference is honestly. I've been on 15192 for ages now and it's been fine up to this point... Think I'd just as soon keep it. Thanks for the suggestion though.
I Read some where online. That if you take out the Sim card let it for like a minute or so. Slap it back in and there you go. It work for me

Yeah, did that... battery pull and sim card pull... left it out for 30 min then back in... no difference. Like I said, it's not that I'm having a huge problem with my data connection, it's just acting... strange... kind of all over the place. Lots of fluxuation, odd readings/bar equivalents, and the whole 0dbm 99asu thing with still being connected. However I've also now started seeing higher than normal "time without signal" percentages... Just flakey. And frustrating... no issues at all until the 4.2.2 ota.
mine is not really a problem but I had way more bars of coverage in a multitude of places (work, home, gym, etc) on the old radios. I havent looked at the dbm's but visually it's different. might be something for someone interested to look into.
btw, im in fresno, ca.

Well Google changed how the signal is read visually through the bars to provide a more accurate reading. You should look at dbm

Having the same experience here (Whidbey Island, Washington) where the 4g signal clings on until it absolutely had to fall back to 3g. New radios may be contributing, but the change in coding to report lower signals may have improved the ability to hang on to a 4g signal. Hand off seems pretty slick too, but that's likely a function of the new radios that came in the OTA.
