[ CDMA / Verizon ] question on bad signal issues..

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.

Possible radio issue on device w/ ROM juggernaut 5.0

So recently I've noticed that my 4g connection is dropping down to 3g a whole bunch when I'm in an area with very good coverage of 4g. I don't know of any issues related to this on any post I've searched for online so far. There might be one but haven't found it yet though. If anyone can give me some advice to this issue id appreciate it cause I'd love to utilize my phone as much as possible.

[Q] best modem for galaxy s 3 (sprint)

i tried different modems and i found the number one for my galaxy s3 that is L10VPBLIF,,so for 3g is very fast and keep my signal vey strenght ,,,what about u?....

The optimal modem will be different from person to person based on location. LIF might be best for you, but it might not be as good as LIH(for example) for someone somewhere else.
I personally don't notice enough of a difference to care, I try to download large things on wifi anyways, because it always seems faster than 4g

It's mostly placebo anyways.

you right!!! depend which rom u have and the device and also kernel i think but for me in boston that works fine,,,,

And best is what is best for you. It is different for everybody.

I can tell you with CQI, RSRP, and RSRQ numbers to back it up that LIx basebands are better than LJ7 for LTE. Why Sprint went with whatever they did in LJ7, while being FAR better than ICS basebands, disappointed me. I know this because I have mapped 63,839 data points in Sensorly in the past month for a realistic LTE coverage map versus Sprint's flat-out lies they show on their own map.

Mutiny,
Do you publish that information anywhere? I'd like to see what you've mapped in KC.

I too would be grateful to see what you've compiled...

I have been trying a variety of ROMs and Modem. For instance, tried the LJ7 modem yesterday and that just didn't work. I couldn't get a decent data connection on 3G or 4G. Then I went back to the LI3, which I had been using for a while and I had a great 4G connection for a while. Then it dropped out and no matter what I have done thus far I can't get it back, even when I step outside where I can usually get a signal. I mentioned to someone yesterday it's like the Sprint LTE service is operating like a rotating airport light (the green and white lights that I recall from my youth I watched race across the night sky). The beam of service sweeps by and you get it for a flash. I'm really missing the consistency of WiMax on my EVO.
I have been a Sprint customer since late 1997 and to date I can't recall a more frustrating episode with a system roll-out.
I ran across this DSLReports article too and thought it was interesting. http: // goo.gl / ntXCC
Thanks for your post and if you share your research count me among the highly interested.

4.2.2 OTA signal question

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.

HTC 10 calls disconnect

Hey guys, my dad has a HTC10 and he is having a really annoying problem.
he can call people and at random times the calls will just disconnect, he has no signal issues so that kinda made me think it wasn't the common LTE faults, can anyone suggest anything?
Thanks in advance.

perhaps
rooted?
custom ROM?
bad service area?
You've provided no relevant info

my apologies, i should have included more info on the device.
phone is stock, only a few months old, no root and running standard rom and no custom launcher.
service in the area is fine, and it happens everywhere he goes, signal doesnt seem to make a difference, i've got him to keep an eye on the signal strength when it happens but he said the bars are always full.
thanks
