I have been running chingy's re-engineered and the rom rocks as well as cell reception! I went to cm7 to see what it's like and cell reception is horrible. I also tried redemption rom and noticed cell reception was horrible as well. I am back to re-engineered and 3g is consistently connected with anywhere from 3-5 5 bars, but when I was using the other roms mentioned I would see weak 3g signal and occasionaly switch to 1X. I tried searching and couldn't find anything on this issue. Anyone have any ideas?
I have also read that the issue is a cosmetic thing which I can understand. But when it switches to 1x, that in my eyes is an issue. But its strange that this only happens with incredible roms built from source and not with evo roms.
Chingy's ROM using the EVO's 6bar signal strength meter, but CM7 and most stock ROMs only use a 4bar signal meter. This is why you see a perceived difference, but honestly I've never noticed a performance increase or decrease for that matter when I switch betweens ROMs regardless of what my status bar says.
Thats what my thinking was. But, I see full strength with chingys but actually switch to 1x from time to time on cm7, which is the wierd thing.
i dont know if signal is worse, but i think they handle the lack of signal differently.
I am using myn's and when there is no signal and you try to make a call it fails immediately with no error at all whereas with the stock rom it would say call failed.
Different ROM's measure the reception differently, if you go into settings > about phone > Network -- you'll see the dBm measurement of your signal.
This jumps around a fair amount too, so take that into account. It will vary depending on where you're positioned in your building / house, the weather outside, etc.
Your signal should be exactly the same from ROM to ROM, flashing a new Radio is pretty much the only thing that will change that, and those aren't included in ROM's.
Sounds good! Currently running Miui which is great, and haven't lost 3g yet so maybe the past flashes were just flukes.

I'm at a loss here, but I know something is wrong for sure. I'm familiar with the low signal strength 'problem' on LTE networks as described at rootzwiki's thread entitled "This is why your Verizon Nexus signal "sucks" " I do not understand it inside and out, but I know enough to be at least 80% sure that this is not my issue. That thread describes a low signal strength, as in the dBm, but my problem is actual performance. I'm not comparing numbers (at least not on LTE networks), but results.
The problem is pretty bad, and pretty consistent. Without fail, my signal strength will be butchered, and with it data and even voice/text service will be unreliable or non existent inside any building. Not just some buildings, but any building. If I'm in a 4G area, I almost always lose the 4G, and it's switched to 3G with very poor performance (even for 3G standards). If I don't loose the 4G, the speed test results are horrid. I've had several cases where inside a building I still have 4G but the speeds might be 500-700 Kbps down/up or even worse, but when I step outside into the parking lot, 10-15 Mbps down 5-15 Mbps up. I realize structures absorb wireless signals and sometimes it can be pretty bad, but this is too much and too frequent to just be normal wireless signal degradation. It also doesn't seem to be the area because I've traveled through these areas before with my droid charge and I've never experienced issues anywhere close to this bad with my charge.
Some examples; the first time I noticed it was in the Greensboro, NC 4G area. Specifically at the Travel Centers of America about 10 miles east of the greensboro's border. When I first pulled into the truck stop (I drive a strait truck with a sleeper) I was pissed because my phone was on 3G, and I looked this area up before I came here on verizon's detailed 4G coverage map. This very truck stop was sitting in a dark maroon 4G area, NOT an extended 4G area. So I was angry, but I figured that there was an issue with the network, or the storm coming through was causing problems. Later the storm passed and I noticed (while walking back to my truck) that I was getting a strong 4G signal and good speeds, 5-10 Mbps down and 5 ish up. But as I sat back in even just the driver seat the signal strength dropped, and so did the speeds. I did a lot of tests later outside. I was performing speed tests at different locations all over the parking lot and I noticed the closer I got to the trucks, the poorer the performance. When I was inside my truck, and back in the sleeper, 4G was gone completely, taken over by a very poor 3G signal with slow speeds. I found that if I had my phone mounted on the windshield I was able to get reasonable 4G speeds, but still only a fraction of what I was able to get outside in the parking lot.
Another similar case happened in the Washington DC area at a walmart (Landover, MD). This time the 4G stuck even in the sleeper, but speeds were 2-3 Mbps down and about 700 Kbps up. While outside, however, 15 Mbps down and up.
Here I sit at another truck stop. This time, however, I'm in an extended 4G area (which of course means I have 3G) and I'm comparing my 3G signal strength to my Charge's signal strength. I know what I said earlier, but from what I understand about that "issue", gingerbread phones and earlier would give the CDMA signal strength because they couldn't read the 4G signal strength, but ICS and later can and so it displays the LTE signal strength. So wouldn't that mean that if you are in a 3G area, you can, in fact, accurately compare signal strength since they should both be displaying the CDMA signal strength? If that's the case, then what I'm getting is -100 dBm on my Galaxy Nexus and -87 dBm on my charge.
Something is most definitely wrong with my phone, but I don't know if it has anything to do with the Vicious JB stock rom I installed or not.
Vicious JellyBean 4.1 V5 is the version I installed, and I realize now that I did not install the latest (4.1.1 V1) but nonetheless I could not see it reported anywhere in the changelog, or any of the replies to the thread that there were very noticeable problems with the radio performance. I'm just at a loss and I really hope someone's reading this going "ah, I know exactly what that problem is". Although I'm never lucky enough to have a well known problem happen that there are fixes readily available for
Thanks very much for your time and help!

JB issues?
Soundfx,
I've noticed some strange data problems as well. I've only had my nexus for 3 days. The first thing I did was throw a JB ROM (actually, about 9 of them to try them all out) on the device. (Vicious was one of them) What I noticed was that pretty consistently, about 5-10 minutes after the flash, my phone would go from having 4 bars of LTE to no signal at all. My connection would drop completely. Although I didn't figure this out until the latter flashes, I did remember having connection issues when I tried going to the play store or the internet on all the ROMs. I'd have to switch of LTE, and then I'd start working again. At first I just figured that I'm in some sort of LTE dead zone or something. But it seemed strange that my connection would drop completely and I couldn't get it back for 30-60 seconds.
SO, this morning I took my device back to stock. Unrooted ICS from Verizon. And although I wasn't at home for more than a minute to do testing, it appears that my connection problems have gone away. So I'm wondering if it is a radio issue for JB roms. All that to say that I don't think your problem is just the vicious rom. If you wouldn't mind, I'd suggest you trying another ROM and seeing if you have the same issues.
I figure it could be a few things for my own issues, which could be similar to yours:
1. Toro JB roms just have radio issues. (Seems like more people would be clamoring on this forum though if that were true, and I haven't seen any other than you)
2. I have a bad piece of hardware. (Running my stock ICS rom should shake that out.)
3. I live in a verizon dead zone and will experience drops no matter what ROM I use. (Again, stock ICS should shake that out for me.)
4. Gnex has inferior radio hardware, and there is nothing to be done about it. (Doesn't seem likely.)
ALL that to say that, while I don't have an answer for you, I seem to be experiencing similar problems, and I'm trying to figure it out too.
I'll keep you updated as I hone in on a culprit of my problems. (IF I can)

You say "the AOSP" version that was released, but what exactly does AOSP mean? I know what it stands for, Android Open Source Project, but every jelly bean rom I've seen (or most) has AOSP in it and I guess I don't grasp it's actual meaning.
The only thing I know for sure is that I want stock stock stockity stock stock! When devs build roms they tend to always have some sort of a bug or two, and I just never feel like they are stable enough. So I want as stock as I can get! Which is why I installed Vicious Stock JB.
I just really don't know though...I know the nexus apparently has radio problems anyway, but...I guess I can just try the latest roms and see what happens. Are there any radios that I can install maybe that would fix this? :\

Thank you kindly sir, and I will give a few other roms a shot just to see what I can find out and report back!
I tried flashing a few different roms; Liquid TORO Alpha 6, Vicious CM10 Toro, and Vicious JB 4.1.1 v1. All three of them as soon as the phone booted up showed the exact same poor 3G signal quality in the back sleeper while I'm in a dark maroon 4G area. Although I don't think I did a proper rom installation. They roms definitely installed, but it upgraded and installed over what I had...which I didn't realize it would do at all. I'll try doing it properly rom installation with a JB toro rom and then I'm going back to stock ICS to see what it looks like. I'm actually, right now, back at the truck stop that I originally noticed this problem. I'll post back.
I tried flashing back to stock 4.0.4 ICS build with the most recent radios, then I tried EK06 EK05 radios. It was the same across the board. No matter what rom/radios i use, the signal quality was the same. I lost service completely inside the building and in the sleeper it drops to 3G with incredibly poor signal quality :\ -100 dBm -120 dBm I'm going to try and get a new SIM card. if that doesn't solve it...then I guess it's time to look for a new phone :\
It seems like the developers are in a holding pattern until new radios are leaked. If it's that bad, there's no real harm in sticking w/ ICS until we get radios. Some really sweet things have been done by the community in the meantime.

well I already had vicious 4.1 installed with my apps and all that stuff and it's the same across the board. So I'll be sticking with this until something pops up I guess :\ I'm still definitely going to check about getting a new SIM card; it's the only option, short of another phone, that I can try at this poing. -shrugs- :\
I have been trying to figure this one out for ages!!!
Can anyone answer why TW roms report signal strength different from AOKP. (I don't mean 4G vs LTE or faster or slower speeds) When I have a TW rom installed, I can go virtually all day and have no reported signal loss, but if I have a AOKP (all source android for that matter) installed and I use the phone in the exact same place I have as much as 50% time without signal while the whole time I actually have signal as I use the phone. On the TW rom, signal almost never goes less than one bar but yet I can have no signal at all, but if it is like that for any amount of time then it will show no signal, but the AOKP will show no bars but still have signal and yet it still reports as no signal.(maybe there is a different scale for signal strength) This doesn't just on my phone, as I have 3 that I tested on with the same result. There is no problem with signal as I have said and the phone works fine during this time unless signal is lost totally. Some say TW has faster DATA and BETTER signal, I have never experienced either, both seen just as fast, which is why I wonder if sammy does it on purpose with some code or if AOKP has a smaller scale in which to report the strenght, hench my issue.

Did you actually check the signal dbm or just compared with the signal bars?
The signal bars are just images, therefor, you could set it to show 1 bar and actually have full signal db.
Compare their dbm and you'll see if there's actually a difference.
Another thing, keep in mind that every phone is built differently and one could have 3bars of signal while the other has 4bars, both phones running the exact same thing.

I've noticed the same. On TW I show 3 bars and on AOKP I show 1 bar. I believe it's just as you said the signal image reads off the dbm and AOKP might be set to show 1 bar off -108dbm with TW is set to show 3 bars

Aosp bases roms show signal more accurate then TW based OEM roms. We even found that att had changed some images early on to show more bars then what you were really getting.

Maybe for some folks it's just showing up like that.
But in my area, TW ROM's get me faster & better signal than ANY AOSP ROM. Hands down, flat freaking true. I've tested it with speedtest and speakeasy.
TW consistently gets me a better signal and about 20% faster download speed than any AOSP ROM since the ICS to the current 4.2.2 ROM's.
And not just on one phone either. I've had three S3 warranty phones (don't ask. lol). They all behaved the same way.
I've done "scientific" (as best as I can) tests and it's been very consistent like this. TW just gets a better signal I figure, which = faster download speed. I don't know how else to explain it.
I should also state that I'm on the edge of LTE area. AOSP ROM's usually give me about 1 or 2 bars and 5-12 mbps download speeds.
When I get closer to downtown, I get 30+ mbps download easily.
TW ROM's give me 12-18 mbps where AOSP struggles to reach 12 mbps. In the same exact location on my desk.
The speed is something else completely. That has nothing to do with the amount of bars shown.

Well to be honest it has to do with 2 things. One is how the software talks with the hardware. Second as I stated above. There have been times the carrier have flat out lied about how many bars you have. We found this when ripping the apks apart and there instead of being 0, 1, 2, 3, and 4 bars they removed the 0 and 1 bars and replaced them with the pngs for 2 bars.

Ya its weird, as long as it shows 1 bar, then it will not register signal loss, but soon as that bar disappears, but still with signal, it will register as loss of signal. When there is no signal there is a diff icon, so then and only then should it report as a loss..... I would like to fix but so far I have found nothing concrete, just options.
I think CM shows the true signal bars whereas TW shows the fake one.

A lot of times if it shows no bars yet you still have signal ie. Still able to text, call, surf Web it's because you're transitioning from 4G to H+ or whatever the transition maybe.

Well I have found some info, I am going to try this and based upon the results, I will post back so that anyone that wishes to modify their rom (if it works) will be able to do so.
The problem that I am referring to has nothing to go with the transition from 3g,h,h+, or lte for that matter. connection does not change, problem happens when you are in an area that has a lower signal, thus being able to USE the phone even though there are no bars.

I have been using CM10 for awhile and usually find it to be great. However recently I have noticed my phone doesn't seem to last a full day anymore and this is minimal screen time. I updated to CM10.1 (RC2) when it was released, I'm not sure if that contributed or if there's something else I'm missing. I have found the best performance by disabling LTE and using WiFi whenever possible. Still though it lasts 9 hours with about 1h30m screen time. If I use it anymore the battery may only last 5 or 6 hours, and this is just using it for occasional web browsing and some texting.
My service provider is Koodo (Telus) and I live in Burnaby BC, so I usually have a pretty good cell signal.
I have attached some screenshots of my battery usage. This was on a day with only light usage and no music or media used; LTE was disabled and WiFi was on.
Any ideas as to what could be causing this, or if this is normal would be appreciated.
Thanks!

Did you update your bootloaders? If so, you probably have the LK4 modem, I'd try flashing the LL1.
Also, you can download BBS (BetterBatteryStats) from here to help narrow down what drains your battery.
It has been known that CM10.1 has been giving poor battery life ever since the Linux 3.4 kernel rebase. I'm not sure if there is a fix, or if the CM guys are working on it at all... It has been 7 days since the last kernel commit for d2.

I can support this, I am getting about the same battery life as you. Ever since updating to RC2 I have noticed that my battery life has diminished. I have a spare samsung battery, and normally I wake up, boot and go to school and use my phone a fair amount for texting, researching, and music. A full charge will usually support this until around 10-12 hours later, then I change batteries in the evening play more music and web browse. I took a screenshot of my battery history a few days ago, you'll notice that the graph increases without the phone ever being connected to a power source.
Has anyone checked their "Cell Standby" to see if there is any time without signal showing?
If you haven't toggled your LTE off, have a look sometime and let me know. If it is showing a percentage of time without signal, go back to your battery life graph and see if there is any RED in your Mobile Network Signal. If you see time without signal but no red in the bar let me know.
I've got some ideas on why battery life isn't great and I'm trying to build a case for it. Guys who frequent locations with poor LTE (4G) signals are who I'm mostly looking to get data from.
Any information that you guys might have would be very helpful to me. Screen captures are welcome. I've uploaded a couple of myself to show what I am talking about.
Cheers.

Poor signal is one hell of a battery drainer. I would suggest trying different modems to find one that works better in your area.

No no. Modems do not affect this issue at all and with the new phones now a days modems don't play as big of a role as they used to with signal strength. Anyway this issue is bigger than that. CM10.1 isn't reporting 4G low signal strenght correctly. It jumps from -115 at one bar to 0dBm no bars instead of switching over to a 3G signal or showing a value that is accurate like -117dBm.
Flashing back to the M1 release of CM10.1 or even to stock and the handoff from 4G to 3G is seamless. We aren't seeing that anymore with the later released even as early as RC1.
Here is my JIRA report.
https://jira.cyanogenmod.org/browse/CYAN-1209
You can see I've put some work into it. Trust me, this isn't a flash a different modem, change network preferences or anything type of issue. I've tried all that before finally starting to gather some screen captures and information on the way the phone is handling it's network signals.
I've also talked about it extensively in the CM10.1 Nightlies thread in the dev section over the last week or two.
http://forum.xda-developers.com/showthread.php?p=41931891#post41931891
Also my original post was asking for anyone who has seen a time with signal recorded under cell standby BUT NOT showing any red in the mobile network status graph. Different than just no signal at all and red showing meaning you have no connection to the carrier at all.

https://jira.cyanogenmod.org/browse/CYAN-1209
You can see I've put some work into it. Trust me, this isn't a flash a different modem, change network preferences or anything type of issue. I've tried all that before finally starting to gather some screen captures and information on the way the phone is handling it's network signals.
I've also talked about it extensively in the CM10.1 Nightlies thread in the dev section over the last week or two.

Also my original post was asking for anyone who has seen a time with signal recorded under cell standby BUT NOT showing any red in the mobile network status graph. Different than just no signal at all and red showing meaning you have no connection to the carrier at all.

Well then, I stand corrected. Great work, thanks!

Has anyone checked their "Cell Standby" to see if there is any time without signal showing?
If you haven't toggled your LTE off, have a look sometime and let me know. If it is showing a percentage of time without signal, go back to your battery life graph and see if there is any RED in your Mobile Network Signal. If you see time without signal but no red in the bar let me know.
I've got some ideas on why battery life isn't great and I'm trying to build a case for it. Guys who frequent locations with poor LTE (4G) signals are who I'm mostly looking to get data from.
Any information that you guys might have would be very helpful to me. Screen captures are welcome. I've uploaded a couple of myself to show what I am talking about.
Cheers.

I can probably come up with some data, when I'm at work I generally get a low signal, I never toggle LTE, though I live in a town of ~8000 people, far from major centres. I believe we have HSPA+, but I'm generally connected to 3G. Right now, I've had normal battery life, (no increasing), and 0% time without signal, should I ever have <0% I'll message you some data. Thanks for your work!
I can confirm that I'm having this issue as well. I live in a 4G city (Boston), but my high school has practically no 4G reception. I noticed that unless airplane mode is enabled in the school, I have a battery drain of about ~1 per 5 minutes. The battery stats shows certain red areas when the signal is close to 0.
I'm running the latest nightly (5/29), but I'm flashing back to the M1 ROM until this is fixed. If I encounter any issues with this ROM, I'm probably going to flash back to stock.
Hopefully the devs can get on this when they have time.

Battery life has actually improved quite a bit since rc2, but when I'm at school, where the signal is bad (most of the time I get "emergency calls only"), I see faster than usual battery drain as well. I think that this is normal though, because even my old dumbphone drained battery quickly when there was no signal.

Emergency Calls Only and Red in the mobile network history aren't what I'm referring too with my issue.
Those two things would indicate you phone had no cell signal at all to your carrier. I'm talking about being on such a poor 4G signal but still being connected to the Roger's network. It's hard to explain.
Anyway I appreciate your input.
There has been a lot of discussion on this in the CM10 Nightlies thread in the dev section if anyone is interested in reading or check out the JIRA report linked on the first page of this thread.

I'm still connected to the AT&T network, but it's a very weak signal when I'm at school.
Just flashed back to stock, and the draining issue disappeared. I guess there's still some issue regarding cell signal that's draining the battery.
I've got the same issue, I thought it was just me. I'm on Rogers
I even lose battery (about 1% every 30 minutes) while plugged in and charging, if I'm listening to music, and checking my phone once every half hour for texts or emails.
The other day at the gym while listening to music and using 1 note taking app, it went from 95% to 15%. When I checked, it said the phone was active for 1 hour and 5 minutes even though I never used the phone.
I'm going to install that bettery battery status app now.
Didn't see a thread covering this, so I figured I'd start one.
One issue that has plagued my Pixel 2XL is severely diminished LTE signal strength on Android 10. I first encountered this on beta 5, and again on beta 6. My signal dbm's were 10-15 less than on Pie, and the signal indicator was rarely, if ever, above 1 bar. My signal would fluctuate wildly based on location, and would rarely hold steady. Speed tests confirmed things. Extremely frustrating. It was such a problem that I eventually opted out of the beta program and rolled back to Pie before the official release of Android 10. Since then my signal strength has returned to normal and been steady and solid. I have not updated to official Android 10 yet, and keep hoping that this issue will be resolved through a monthly security patch. So far, from what I have been able to gather, this issue has not been fixed. There are several different threads covering this issue, as well as official issue tracker threads with Google:

https://www.reddit.com/r/GooglePixe...el_3_weak_signal_on_verizon_after_android_10/
I am having this issue on my 2XL, on AT&T, however this issue persists across devices and carriers, and doesn't seem to discriminate. As with most things though, there are plenty of folks who say they are not effected by this in the least.
So my question here is this:
Has anyone noticed a decrease in signal strength on Android 10 on the Pixel 2XL?
LTE? 3G? WiFi?
Fluctuating signal? Dropped calls? Poor data speeds?
I'd really love to update to 10, and the latest December patch, but am extremely hesitant to do so, based on what I have personally experienced and read in the above threads.
Any input, opinions, personal anecdotes are welcome. Thanks in advance.
I haven't had any issues with LTE signal as you described, but I have had problems with WiFi signal regularly dropping. After some research, I found that the issue was with Android and my router which puts out a 5ghz and 2.4ghz signal - Android 10 would drop the signal when switching between the two. My solution for home was to turn off the 5ghz channel on my router and my issues with WiFi went away.
I don't use WiFi away from home frequently enough to see if this signal issue has persisted on other connections, hoping for a fix in the December security patch.
I am running Android 10, rooted with Magisk. Clean installed about two weeks ago and the issue was apparent from the get-go. Never had anything like this in Pie.
I can't say for sure on the LTE side as I never checked numbers prior to updating to A10B5, however signal strength barely shows on the indicator. Tower is 4 blocks away. My wifi is terrible and there appear many variations across Pixels. No solutions here but appears to be a widespread problem. FYI.

UPDATE:
Last night, I received and flashed the OTA update. I went into my home route and turned on the 5ghz channel again and the WiFi issue immediately returned for me. So, sadly no fix in the December patch and at least in my experience, this is limited to 5ghz connections. For now, I've reverted by home WiFi back to 2.4ghz and it's working fine.

Thanks for the update on the WiFi side of things. Sucks that that hasn't been fixed yet, after months of it being a known issue.
Just out of curiosity, how is your LTE signal strength on the December update? Dbm's and signal bars appear to be normal? Any dropped calls or slower than usual data speeds?
The WiFi issue sucks, but at least it can be worked around for now. There is no substituting for poor signal and connectivity though, and that is still a deal breaker for me moving forward.
Thanks in advance for any input, I appreciate it.

If there has been a change with my LTE signal strength, I certainly don't notice it. I haven't had any dropped calls or slow data speeds.

Thanks, good to know. Not to beat a dead horse here, but in general, do you notice less signal bars on 10 than previously on Pie? On the betas, I rarely showed more than 1 bar at any given time, and dbm's were less across the board as well. Frustrating. I realize bars don't mean everything, obviously, and the only way to truly measure signal strength is by looking at the actual dbm's. Maybe something in the Android 10 code changed the way signal bars are calculated relative to dbm's?

No, I haven't noticed a change in bars or dbm's since the update. I live in the city and so my service signal has always been strong - no change since upgrading to 10. I should note that I didn't update to 10 until about a week or so ago and when I did, I did a clean flash and then rooted with Magisk. I have since updated to the December security patch, again with no change to my cellular signal.

Thanks, appreciate the responses. It's actually good to hear that things are normal on your end. Sometimes it's easy to get caught up in the complaints, and in the process not hear about those who have no issues at all. So strange how this bug seems to randomly effect people, across carriers and various Pixel devices. Some are majorly effected, some not at all. Would love to update, but it's a roll of the dice that I'm not sure I'm willing to take.
I’m wondering, why can’t/don’t you merely update to 10, try it out and see how things go for about a week, and if it’s not a good experience for you, merely roll-back using the Full Factory Pie/9 image?
In any case, I am under Verizon and haven’t noticed any lowering of network signal or performance. I do experience some need to re-initialize the wifi – but, to be fair, I had that issue in Pie – but maybe not as frequent.
Either way, many/most have a good enough positive experience that it’s simply at least worth a try; at least on a temporary basis. But, again either way, good luck and hope this helps…

Thanks for the response, I appreciate it. I am probably one of the few Pixel owners out there who are still running completely stock and unrooted, and I also never bothered to unlock the bootloader. So needless to say, having the ability/option to flash back to the factory image for PIe, should things go sideways, would take some work. I'll probably update at some point, but I have had literally zero issues on PIe. It runs flawlessly for me, and always has, so the thought of introducing potential problems makes me a bit hesitant. Just wanted to try to see how widespread this signal issue was., that's all.
