Verizon nexus drops signal randomly

Hey I've had my nexus for about 2 weeks now and its rooted unlocked and running a custom rom based on the official 4.0.4 release. Every now and then I would loose data completely (x next to the signal bars) then it would come back.
This is very annoying and causes dropped calls and some apps that use data to stop working.
Is anyone else having this issue and is there a way to fix it?

Same here...it happened to me on rooted stock 4.0.2 and thought the 4.0.4 leaked OTA would improve, but same behavior. Ugh..so annoying!

I had the same issue. Tried the newest radio with no luck.
Then I went here http://forum.xda-developers.com/showthread.php?t=1469687 and tried hybrid 3 which uses the 4.0.4 cdma radio and the 4.0.3 radio...it works great!!! No more drops!

i am having issues also, full 4G bars then drops randomly causing drop call and data.
i tried hybrid radio but no luck
I am now on my second gnex after returning the first one and still having major radio issues. This phone feels half baked and that is being polite. Can't believe I am saying that coming from a Thunderbolt. Mine is completely useless as phone and I have tried every radio under the sun. I can't use it for more than 5 minutes without it dropping signal data/talk/everything on 4g. What a piece of white hot steaming garbage.

With my phone I would lose data for upwards of a minute when switching from 4G to 3G. Flashing the 4.0.4 hybrid radio seemed to fix the issue
My wife's GNex which is still on the old radio seems to exhibit the same data loss behavior as mine before flashing the newer radio
4.0.4 radio did nothing for me, but 4.0.3 seems to have fixed this issue on my phone.

[Q] Rogers S III Running CM10

SO far, none of the CM10 base builds have worked for me. Wifi is constantly dropping. I was wondering if anyone is running CM10 on a rogers S III and has no issues. Today is my last day to exchange the product so if it's just 1 in a million, then ill get a new one.
Thanks!

I have a Rogers Galaxy S III and CM10 Runs perfectly you should exchange yours if the problems continue but be sure you wipe system factory reset before installing CM10.
Worked fine for me while I was running it.

I had issues with my SIII(Rogers) with WiFi constantly dropping. No matter what I flashed it continued. Its a known issue on all variants, not just Rogers.
I exchanged mine and my new one is flawless

finally did the exchange at Future Shop and now all CM10 ROMs have zero wifi issues! If you are having similar problems with custom roms i highly recommend you get a new one!

[Q] Constant Signal Dropping on Cyanogen Based Roms

I've been having an issue on AOSP Roms where my Signal Strength can go from full to zilch and seconds later back to full. This constantly happens and seems to be worse over WiFi.
I have an unlocked LG G3 D851e from T-Mobile that I am using on AT&T Network. When using the stock ROM or using a Rom like Cloudy service is impeccable and does not drop.
From searching other threads i see to be sure SElinux is set to Permissive and it is. I have no battery saving apps or any app that could cause this.
Currently on SOKP unofficial 5.1.1
However I was on AICP, PA, and resurrection remix within the last few days.
Baseband: MPSS.DI.2.0.1.c.1.3-00053-M8974AAAAANPZM-1
Stock is too clunky and slow for me ( Same with Cloud) however with my service dropping i miss calls, have poor call quality, and text messages seem to come in delayed.
--Note--
This has happened on my Note 3 Unlocked HLTETMO where i ended up selling the phone recently and started using this only to have the same problem.
Surely there is someone else having a similar issue!? Or someone who knows how to fix this ?
I have been having the same issue since 5.1 came out. I have yet to find a fix. Going back to stock helped but as you stated stock is ugly and very awkward. I guess we will have to hold on and see if it gets sorted out.
This isn't device related, I'm having this issue on the Oneplus One and G2 also. Even my moms nexus is doing it. All of us are on T-Mobile, wonder if its our network

I'm on AT&T with an Unlocked T-Mobile phone. It is ONLY on AOSP Roms, stock roms work fine. It did happen on my Note 3 that was also T-mobile that I unlocked and used on AT&T. Something happened early into lollipop that caused this, as ROms pre lollipop worked fine. It is the most frustrating thing to me, and it is the reason I plan on getting a Nexus/OP2 very soon. Unless Android M comes on the G3 and fixes the issue.

cm-12-20150214-UNOFFICIAL-endeavoru-big. No phone signal

Hi all
Am running cm-12-20150214-UNOFFICIAL-endeavoru-big on my HTC One X International Version. All went well for a week. Now the phone signal is really low. In fact mostly there is not signal at all.
Anyone have this experience? And a fix?
Thanks
Well, this is a pretty outdated version and i would suggest you to upgrade on cm 12.1. Since then many big bugs has been fixed.

Thanks, installed resurrection remix. So far so good. Nice ROM

software version impact on signal strength and connectivity?

Recently purchased a used sprint note 4... And I'm in love. I had a s5 that was dying a slow death. I love the spen and larger screen... This is indeed the perfect phone!
When I purchased the phone, it was on base qb3. I was having problems with root/rom/sms and I flopped around for a while.
Currently on base pg1 with a stock (mod) 6.0.1 rom.
I've been having problems with signal dropping, occasionally missed sms/mms and poor connectivity.
My question is..
How much of an influence does the base have on signal reliability? I have searched around and I can't seem to find d a solid answer.
Which 'modem' provides the best/stable connection?

I can't say from experience or speak for everyone else. But 2 people i know personally like PK1. But i think that has more to do with being friendly with more custom roms.

Thanks for your input!
I'm hoping someone might now if the base software has any impact on the strength of the antenna... ie - how good/stable the phone connects to sprint.
On pg1, I'm seeing dropped signals without valid explanation. (places my s5 had great signal... Note 4 is barely connecting)
Wanted to follow up...
Went from mm to nougat (lineageos) to mm.... Finally went to lollipop.
Baseband does have a direct impact on signal strength/reliability.
While the note 4 is inferior to the signal strength on my previous s5 (same spots at work, etc)... Going down to lollipop has eliminated dead spots I was experiencing in mm.
Interesting find. I was on pj1, i got decent lte signal in my room at home. When i leave for work i roam, which sucks, but whenever i come back from work I'm stuck on 3g. 3g for days. Pk1 seems to have gotten the lte to stick... I'll know more when i go to work tomorrow.
