I have read through the FAQs and seen several posts from users of other phones and other networks with the same issue, but there has not been an answer to be found.
I've experienced this issue with 4 different ROMs now, so it's not ROM-based. I've tried 3 different radios, so it's not likely modem-based.
The issue is that I will get voicemail notifications for calls I miss, but I'm sitting at my desk with my phone and it didn't ring, nor is there a missed call indication. 5 minutes later, someone else might call me and the call comes through fine. It appears to be purely random. People who call me sometimes get through, sometimes not. It's not the same person who can't get through, or the same network.
Does anyone have an idea what is happening?

Your description definitely sounds familiar. There are times when the phone was under clothing or left on vibrate, then there are those back to back instances where you notice because the first call went straight to voicemail and the next one gets through.
Ideas? Maybe not, but there may be some clues worth considering. Every wireless carrier I've used suffers dead spots where you are 99% guaranteed to have your call drop in progress driving by.
Locally (NJ) AT&T has 2 on the westbound "covered roadway" leading to the skyway. My point is I've observed where they won't affect my passenger's TMobile calls. Oddly, when I experience this there, the call has usually gone on uninterrupted through the Holland Tunnel. Must be an infrastructure quirk.
The drive by carrier dead zone is a fixed location call deterrent. An expert could probably say how much each example is based on tower locations versus radio interference. I guess a similar scenario might be possible wherein the call recipient is stationary, like at your desk, and some moving interference breaks a fragile tower connection. I have to say it seems a lot less prevalent with SR vs. previous smartphones and with my current ROM / Modem vs. former ones.

Thanks. No, this is definitely chronic and not related to dead spots. I have my phone with me at my desk, 3 or 4 bars, no issues. Just doesn't come in. It's been really bad since moving to the JB ROMs. It pretty much never happened without explanation (dead zone, etc.) when I was on ICS and earlier. :/
One other performance problem that my Captivate had resembled this.
When I complained to Customer Service, they did some kind of remote (non-destructive) "reset" of my account. That corrected the random call drops I had reported then.

Were you dropping calls midstream, or not receiving calls? My problem is with not receiving calls when I'm somewhere I usually do and at times when my cell service looks fine (adequate bars).

Now that you mention, I recall it was a mix. Bars were good, some calls were silently missed, others FCd the phone app while ringing in, forcing reboot. Good, stable calls surrounded the (<5%) failed ones. AT&T's account reset corrected both issues. Stock ROM back then was Éclair or Froyo.

15 years of using mobiles, never heard anything like it. I can hear myself when I talk.
It doesn't happen all the time, but happens at least several times a day.
It's NOT an echo. There's no delay at all. When I speak, it comes directly to my hearing.
It's not a network issue, as it happens with different networks and with VOIP as well (Line App etc...).
It's usually okay in the beginning of the conversation, but then within a minute or two it's like a "switch" is thrown and I all of a sudden can hear myself talking and it doesn't switch back until the phone call ends (often it will continue into the next call as well, for example if i call them right back).

Bumps... I also should mention the phone is brand new.
Think this is a driver issue? or something that could be debugged? The shop thinks I'm crazy because when I go to the shop I can't get the problem to reproduce.
I would assume its a hardware fault. Contact the phone provider and get it tested/fixed.

The issue was found out. When the phone was switching networks between CDMA and GSM in the middle of the call was when it would happen. This was determined by making 30+ calls in various subscription modes and visually seeing the network type switch from H to G and then suddenly being able to hear myself talk. With the phone on GSM only or CDMA only as opposed to auto, the problem never occurred.
Hi guys
I've tried researching this issue from time to time but have never been able to find any definitive information. A couple of threads around the traps detailing similar problems, but that's it. Anyway, what happens is this: the phone will be showing a couple of bars or whatever, but there actually isn't any signal at all. Calls can be initiated, but wont actually connect, and then can't be ended either. The only way to resolve the issue is to reboot the phone, or activate airplane mode and then deactivate it again (which tends to take considerably longer than a simple reboot). I'm calling it a radio crash because that's what it seems to be, but I could of course be wrong about what is actually going on under the hood.
This post is basically part of an effort to diagnose the problem before I decide what this phone's future will be (have a new, different model on the way now).
Thanks for reading, and any advice/information will be much appreciated
It sounds as if you have a defective phone, or it could be you carrier.
Have you tried a different phone.
Do other people have the same problem with that carrier
You could also think of it like this, carrier problem, you can connect to wifi if it doesnt have internet connection, it still can show full bars but nothing will load

I have an SGS3 now, with the same SIM in it (cut down to micro of course). Average signal strength (as reported by third party apps that don't pad) is about the same, but no dropouts at all (as monitored and reported by the No Signal Alert app). However the SGS3 supports both my carrier frequencies, and the Atrix 2 doesn't. Having said that, the SGS3 seems to stay on 2100MHz all the time anyway where I am.
I've also put a different SIM in my Atrix 2, from a network that is more compatible (850/2100), and although the dropouts are less frequent, they are still occurring. However, I haven't had a "radio driver crash" in over a week. The dropouts have only been momentary too, lasting no more than a few seconds, 1-3 times per day (mostly in the afternoon).
I'm also planning to charge the phone up and leave it at a couple of other locations for a day or two while continuing to monitor signal interruptions. Should be interesting.
Thanks for the reply
Just a quick update: left the phone at another location for a few days where the average signal strength is stronger, and not a single dropout was logged during that time. In certain areas this phone is obviously not as good as some others at maintaining a signal, but I don't think the dropouts themselves are indicative of a fault given this new information.
The previous instances of radio lockups/crashes are still haunting me a little, but this strange phenomenon is still yet to occur again. I also forgot to mention that I'd previously done a full restoration of the official 4.0.4 ICS release in order to return to the phone completely to stock, which might have something to do with that. Previously it was rooted, with only some minor modifications, but I guess it's not beyond the realm of possibility.
Wait i have an idea
Send me your apn data.
Motorola doesnt have the best antennas either.
Also does it crash at a certain time after it is turned on or is it random?

Hi guys. I've got a saga to describe for those of you who are interested, but I'll try to keep it brief. I think it really boils down to one or two simple issues.
I've had Verizon phones for a long time, in Central Illinois. Probably about 10 years now. Rarely had problems with dropped calls. My previous phone was a Droid 1 ... worked great, very rarely (as I recall) had dropped calls.
Then in January 2012, as the Droid was killing me with general Android lag and unresponsiveness (but voice was still fine), I upgraded to a Galaxy Nexus. Loved it for Android performance. For the first 3 or 4 months I had it, I don't recall it giving me any undue trouble .. dropped calls were minimal if any, I think.
Then sometime around April or May, started getting a ridiculous number of dropped calls. Mostly at my home, throughout the day, but not just there, I've also experienced them a mile or two away from my house. The neighbor hood is fairly wooded, but that's never been a problem before.
Additionally, my wife has a "feature phone" (non-smartphone) also with Verizon and very rarely if ever has dropped call problems.
The topography at my house is along a river, we're right near a high bluff overlooking the river, with line of sight (besides the trees, of which there are not a ton, really) for at least a mile or so across the river. I think we're possibly within range of several cell towers.
I notice at most points when I'm in my house, using some apps that help you track signal strength and show you the cell tower ids, that I'm mostly one just two different ones, both of which seem to be maybe about 1 mile away. Also, if I'm walking up one flight of stairs, I pretty reliably see that same app showing the phone switching among possibly as many as 4 or 5 towers, in the space of about 5 or 10 seconds!
I suspect this may be caused by the topography in my area.
I also suspect that most of my dropped calls *may* have something to do with being in range of so many towers, or with the phone switching too frequently (or unnecessarily, really) among the towers, while I'm on the call, if this is possible (I have very little technical knowledge of cell phone radio technology -- hence this post).
Now, I've done a fair amount of research and talked to Verizon customer support about this at length. They've actually been very patient and good with me, but we still haven't arrived at the solution.
I originally thought the problem my be the Galaxy Nexus, but after getting a warranty replacement on that one, and even getting to try a Droid RAZR and then finally the GS3, I'm seeing virtually the exact same behavior on all of the phones. The symptoms do *not* seem to be directly related to signal strength exactly. I get usually about 50 - 60% of the total bars (maybe 3/5 or 4/5) in most parts of the house, yet *still* get these persistent drops.
Verizon's final best solution for me, basically, was to use a Network Extender. Despite my misgivings towards this, I have acquired one and it does seem to solve the problem for me, when I'm home, and when I'm in range of the device (its range seems pretty good in my house). One big problem with it though, ridiculously, is it seems that whenever it's on, my wife's Verizon phone starts dropping calls (and it never does otherwise). So there's a Catch-22 there, added to the fact that I'd rather not have to be running a Net Extender *and* the fact that I still see other drops when taking a walk or driving at least a mile or two from my house.
So, for those of you still with me, I'm wondering if
a) my theory about excessive switching, etc., is plausible, or if you have another one based on the facts I've outlined
b) if doing something like flashing an alternate radio ROM (I barely even knew there were separate ROMs for the radio -- I've done some rooting before of Android, but not the radio) might give me some more control or better performance. It'd be great if there were a setting somewhere where I could tell the phone to be less willing to switch towers or to give a higher preference to one tower, at least while in a certain GPS area (I know, I'm sure it's a reach).
Anyway, looking for a little education into why your opinions are of what may be causing this and if I have any remedies available that are feasible and may actually help.
Thank you for your attention and expertise.
Anyone else having problems with sending and receiving calls on their S3 in areas where they should be having no problems?
I got my phone at launch and it seemed to work fine, I noticed the connection issues after a couple of weeks and figured they would be fixed with software updates as time progressed.
But it's been over 6 months and I'm really growing tired of having to resend texts 5 times and never receiving calls. My phone shows I have 2 bars of 4G yet when my family calls me from the front door of our house (which is 12 feet away from my room) I get nothing. The only reason I know this is because I have the google voice chrome plugin that tells me when I have messages or missed calls to my google voice number, but since I have my voicemail synced up with gv it tells me when I have missed calls regardless of it being to my actual cell number or my gv number. If it wasn't for that I would never know that I missed calls all the time. And I only know I miss texts because my girlfriend gets pissed at me all the time because she thinks I'm ignoring her when I don't reply to texts I'm suppose to receive but never do.
So I've been living with this annoying problem for a while now and I thought maybe it was just my room that had bad reception but I remembered that my previous phone (HTC Droid Incredible) never had this problem. So I tried out my parent's feature phones (LG env 2 and 3) and they didn't have any problems while I replicated the same situations. Their old inferior phones worked better than the nice premium one I paid extra for. Ain't that some bs?
And now I go to a different school that has terrible reception in all the buildings I have classes in. So I always turn on airplane mode and enable power saving to make sure my phone doesn't die by the end of the day. But the other day I asked this random girl sitting by me in the first floor of the student union if her galaxy s3 was getting signal and she said "No, this phone sucks in this building". I asked what service she had and she said Sprint. I didn't know if I should have felt content knowing I wasn't the only one or mad that this phone might have an antenna problem. BUT just yesterday I was in the same student union, in the lower floor this time, and I asked this guy from my class if his data was working on his phone and he said "Yeah I'm downloading a picture right now.", to which I replied back with which service? He said "Verizon", what phone? "Motorola Razer something". At that point I got so frustrated that I felt like throwing my phone.
I mean the phone itself is great, I love using it and taking pictures with it, although lately I've been getting "camera failed" errors a lot. It's just really annoying that it doesn't serve its most basic functions when I need them to work.
So I'm asking if anyone else has been experiencing similar issues and what they did about it? I would have called Verizon sooner but since I'm an added line on our family's plan they only want to talk to my dad. He and I have different schedules so it's always a pain to try and coordinate.
I had similar issues with by i535.
Except the issues appeared the 1st day I got my device, and I was highly po'd to say the least, considering I left sprint the same day because I couldn't complete a call for months. Troubleshot with Verizon tech as is the protocol prior to replacement, and saw the device was faulty. Not communicating with the Towers. Device issue possibly regarding the antenna, but uncertain.
Anyway, I got a new replacement a few months ago, and all has been well.
The cause of your issues may be the same, except yours were delayed in appearing. Hard to tell.
Yeah, I'm hoping to try and get a replacement soon. I'm just scared I'll get a refurbished one that has the same issues.
I've noticed a strange behavior with my T-Mobile V20. It really likes to drop service and then show a loading symbol for a bit before locking onto a signal again.
Usually the current reception is weak (1 bar), but not always. Sometimes it does it when I have 2-3 bars of LTE, just to switch down to 5 bars 2G.
There are also times when it'll show that I have 3-4 bars of voice reception, but the status will say "Searching" and calls won't work. Rebooting will make LTE appear.
Is this normal behavior? I just got this phone, and it's also the phone I used to switch off Verizon. T-Mobile definitely has better coverage where I am, but that's only when it isn't dropping the signal.
I have the same issue with my LG V20 phone. The reception/signal strength is horrible. Callers constantly complain that my phone goes in an out, making it difficult to maintain a conversation. Bluetooth connectivity is also an issue as connecting the device requires multiple attempts. This phone is becoming useless due to the reception and Bluetooth connectivity issues. I will continue to use my Samsung Galaxy Note 4 as a backup. I have never experienced any such issues while using the Samsung device. Hopefully the developers at LG are taking notes and a fix/update will be released before 2017.

I haven't had problems with Bluetooth; in fact, I've had the opposite; Bluetooth works nicely.
I hate to say it, but I haven't actually made a call on my phone yet, so I can't comment on that, but you seem to be having it much worse than I am.

What kind of case are you using? It sounds like you have something blocking the signal (your case), you have multiple, defective radios in your device, or something -- in the area within which you operate your phone -- is interfering with the signal. I am not experiencing those issues at all, and neither is my wife (we're both using US996).
Good luck in any case. Your phone not working correctly is a horrible experience.

Well now that CM14.1 is for all Snapdragon variants, we've got some new helpers.
So I've figured out at least one of the signal oddities. I'm going from one bar on LTE on T-Mobile to roaming on AT&T. I was able to use the app LTE Discovery to see that I was on AT&T's LTE B17 (which isn't even listed as supported on the H918). The phone was just disabling voice and data.
My cell reception seems normal for tmobile(which is mostly not good in my area) but the weird thing is on bluetooth. When i bend down at work with my phone in my pocket the BT signal get choppy. Like im compressing the antenna or something. Weird.

You could take a look at the FCC test for BT https://apps.fcc.gov/oetcf/eas/repo...on_id=Yart0xj3tUt4f53nf7wvbQ==&fcc_id=ZNFH918
I found out that this phone is rated for LTE B13 from there. Looks like it supports a lot more bands than LG or T-Mobile say, since even the FCC doesn't include B17.
