Hello,
I'm asking for some help to diagnose my call problems on UMTS.
First of all, three things happened recently, and let's assume that they happened roughly at the same time:
I dropped my Nexus 5 on concrete shattering the screen completely;
Google released Lollipop which some people believe has problems with 3G and LTE;
I'm using a rather old SIM card manually cut to fit micro-SIM dimensions.
About two days after receiving my Nexus 5 back from guys servicing it (new LCD screen) I had a telephone conversation that was disconnecting once every minute or two. There was no problem recalling though. The same day later I noticed that dialer app says "Emergency calls only" which was pretty weird. I was on Cyanogenmod 11, some recent nightly back then.
My first guess - revert to earlier nightly via TWRP. It didn't help - I was still on emergency calls only and nobody was able to call me. However, I could browse Internet without any problems on 3G.
Second guess - clean flash stock 5.0.1. It didn't help too, however calling went back on for some time (several minutes) before breaking back to "Emergency calls only".
Third guess - buy a starter SIM and check if it works. It did at first but stopped after an hour or so.
Fourth guess - bring the phone back to guys servicing the LCD to check antennas. I've left it for two days. It was opened and antennas checked. Everything was fine, not even a bent flex.
For all this time when on 3G/LTE data transmission worked flawlessly. I could download Google Maps, browse the Internet, whatever. It's just the very basic phone function that acts weird - as if I wasn't registered to a network. Everything seems to work fine on 2G, except for very rare disconnects (once per two, or three days).
So, considering it's pretty weird I'm seeking for help - could it be possible that after hitting concrete something broke down on the motherboard that results in such weird behavior? Or is, perhaps, my retro-SIM dying? Any ideas? Maybe flashing a well-tested radio ROM? Diagnostic apps?

I'm having a rather specific and odd problem with my captivate(s), three of them to be exact. First I bought the phone, upgrading from an Iphone 3g, and the first day it was great, the second day, in the evening, I noticed that it started this strange rebooting loop. The phone doesn't seem to power off because I don't see the Galaxy S symbol it just merely goes black then comes back and searches for the network, finds it, then a few minutes later goes black again, returns, search for the network, and so on. It keeps doing that over and over again. So I tried a factory reset the next morning just to make sure it wasn't a problem with any apps installed. The same rebooting loop happened. So I called a rep and dropped by the ATT store and they said it might be the sim card, which was very very old (still said cingular) so we swapped it. Same problem the next day. Okay so I went and I replaced the whole phone. The second day with Captivate #2, this rebooting loop occurred again. The reps told me that I might have gotten two bad ones and to exchange it again, so I did. And yet again I have the same problem. So here are some quick facts about the problem that I have learned. Total time span has been about 3 weeks.
-The most important thing to know about this issue is that the only thing that prevents the phone from going into this rebooting loop is if I enable flight mode, no network connectivity. I believe wi-fi is okay but whenever I disconnect from ATT's network it stops rebooting.
-Occurs more frequently at night/evening (only happened once in the morning)
-Is not affected by signal strength, full bars, low bars.
-Is not affected by installed apps (Had done factory resets and with my third captivate all I did was put the sim card in and put it in my pocket)
-Is not affected by battery status, low or full
-Doesn't seem to matter if I have a lot of things running or nothing running, the loop starts when I'm browsing, texting, in a call, or just locked in my pocket.
-Does not seem to be affected by charging source (wall, car, laptop, ps3/xbox)
Another thing to note is that I had an Iphone 3G with an unlimited data plan before this. The Captivate upgrade was done on another line on my family plan then given to me with a 2gb data plan. After talking to multiple reps over the phone, they said they had the wrong IMEI number (I have no idea what that means) but that leads me to wonder what else is wrong and is it a problem with the Captivates or ATT itself?
I really need some feedback because I'm about to just give up on this phone, which is heartbreaking because I fell in love it. My 30 days is approaching and if I am indeed returning it, it'll have to be very soon. What do you guys think?
Iv had the AT&T One X since the 4th and so far I love it! I haven't had any wifi issues or bootloops or anything, the only problem I'm having is the phone will randomly lose signal completely (0 bars, little x next to the signal) and wont get it back unless I put it into airplane mode and turn it back off, or reboot the phone. In the 6 days Iv had it it's lost signal 3 times, once on the road where I normally get at least 3-4 bars, and the other 2 happened at some point over night while I was asleep. Has anyone else been having this problem? Also do you think it's a software/radio problem that can be fixed in a update, or would it be hardware in which case I should take it to the store and exchange for a new one.
I've had this problem myself. Had the phone for 19 days now and I think it's happened to me 3 or 4 times.
I can guarantee it's fixable with a software update, even if the problem is hardware-related. At the very least, the software could detect the lack of signal and automatically cycle in and out of airplane mode to fix the problem without user interaction. But I'm sure whatever fix we get will be much more reliable than that.
WHEN we get the fix is another question...
Thanks for the reply. I figured it might be a software issue since you can cycle airplane mode and get it back and I don't really want to take it down to the AT&T store for an exchange in fear I wined up not able to set up gvoice or start getting wifi issues and the like lol. so far the signal drops are far and few in between making it an annoying issue rather than a critical one, and I read we've got root now so even if HTC/AT&T twiddle their thumbs and pretend nothings wrong I'm sure the community can save the day lol
I would swap it out Azure. My first HOX did exactly this, and I saw it reported elsewhere on a number of other devices. To me that says it's most likely a bad radio flash on some handsets. I suppose you could try and flash the RUU that was posted, as it most likely includes the radio as well.
I got tired of all my calls going directly to VM without ringing. And not being able to send out texts. My replacement works much better (or rather, how it should've from the beginning).

Was this problem intermittent?
My phone has been doing this randomly, except it never went to voicemails, just hung up after like 30 seconds.
Wondering if I should switch it out also.
Had this problem for a day. Took my phone to the at&t store and they changed out the sim card and I haven't had a problem since.

I never thought about the sim card being a possible problem...might run up to the store when I get the chance and swap my sim out and see if that fixes it, if not I'll just swap the device out and hope all's well
The CSR actually swapped a new micro sim first, since the one provided via online sales was an older one (most likely from the iphone 4/4s batch). It didn't seem to fix the problem though.
And yeah, the problem was very intermittent. One second it would be working fine, and the next it would show the "x". Sometimes the bars would come back immediately, other times it wouldn't until I rebooted or cycled airplane mode. Luckily it happened while I was at the store; it's much easier to convince a sales rep to swap a phone when they can witness the issue(s).
Yeah it's only happened to me twice since I got it on the 4th... it'll be very hard for me to convince them that there's an issue haha... maybe I'll head down there if it happens at a time when I'm not in class or something. I'm sure if I mention returning it/their policy I'll get a swap.

next time my phone drops signal I'll take it into the store and see about a sim swap in hopes that'll fix the issue if not then I'll reluctantly swap the unit out (I've grown rather attached to this one xD)
**EDIT**
strange...woke up today and my phone completely lost signal again, normally there's a few days between each event but this is the first time it's happened twice in a row =\
So it happened again, I'm going to go get it switched... but it says on the Mobile network section of settings, "Disconnected because service is unavailable."
There is clearly almost full signal strength, and I have never been without service where I live.
I was expereincing constant network drops all of yesterday due to an outage. However, it's back to normal for me today. So it may be possible there's an outage near you as well.
I think it is more AT&T than your phone. I was in down town buffalo at a swim meet with 5 bars of hspa+ on my blackberry bold that has a great radio. I had data but it was slow dial up slow. There were maybe 100-200 people at the meet and it was at a community college. The only other time I had this was when I was in a car that was driving by the buffalo bills stadium. Voice worked but I had no data. I guess too many people using their cell phones.
Definitely not AT&T, my SE Xperia x10 worked perfectly fine, never had any trouble with signals.
I also encounter the intermittent signal drops on my 4 days old AT&T one x.
It seems to me that the One x doesn't hold signal as good as the iphone, my 4 and 4s usually get around 2 bars in some really remote locations of the building I work. But the One X just drops signal completely. I'll see if I can do a sim swap like some others suggested.
I'm starting to think it could be an issue with lte phones because the same thing was happening to me on my galaxy note with 2 different sim cards and 2 different devices and now it's happening on my hox

it has happened to me 3 times in 5 days. All 3 times I was either:
1. in a poor reception area and it came back on its own, i did not have to use airplane mode.
2. was using BT streaming in car and using car charger, once car charger was unplugged, signal came back.
One X has issues
Definitively problems with the phone.
I have three.
They just drop signal completely. One will work, the other will not. Only way the signal will come back is if you turn the phone on and off again. I love everything about this phone....except it isn't a very good phone.
Also, typically when I turn the phone back on, that is when I get my text messages. Nice.
Yeah I figured out it happens when I lose signal (a couple buildings on my schools campus don't get reception), and then the signal won't come back until I reboot or airplane mode.. this is after a sim swap.
Oh and do I need the box my phone came in to swap it?

I have had this issue as well being on the Rogers (Canada) network. I started a thread as well and my theory is there may be a hardware issue reading the SIM cards.
Every now and then I get a "preparing SIM" message pop up on my screen. Also, I lost signal once and in frustration I slapped the phone into my palm VOILA! signal came back full.
This is the second One-X I've gotten from Rogers so there may be a design flaw somewhere. The problem is this behavior only pops up intermittently and cannot be recreated at will. This makes troubleshooting very difficult and practically unprovable in the eyes of providers.
Hopefully there are more reports of this problem and the carriers push back on HTC to resolve the problem.
My new phone is exhibiting strange behavior that I haven't seen any postings about. (okay, one posting, but it didn't have any replies http://forum.xda-developers.com/showthread.php?t=660243 )
I had a Note 2 (AT&T) that worked great for about 6 months until the usb port died. Several ROMS, several modems, no signal problems.
I warranty returned it, and new phone constantly loses or maintains a week signal, until I make a call. Using data, the signal stays pretty weak, and drops a lot. Typically around 1 bar. Browsing the web, the pages hang for minutes at a time. Outbound text messages frequently fail with an error. Incoming calls frequently go straight to voicemail. But, if I dial voicemail, the signal bar immediately jumps to full bars. Now I can hang up, and use a strong data connection for about 3-5 minutes, until the signal slowly drops back down. Toggling airplane mode, or rebooting does not seem to jump start the signal. Making a voice call though, jump starts it immediately every time. Additionally, the battery life seems to be much worse, but I haven't actually benchmarked it. It is the battery from the original phone.
I've tried the phone bone stock with the latest 3 modems, and with CleanROM and latest 2 modems, and with stock and Adam kernels. The behaviour is exactly the same in all cases. It's like the radio just sort of goes to sleep until I make a call.
At first I just assumed it was a hardware issue, because the old phone worked just fine, but the fact that a phone call wakes it up makes me wonder if there's more to it. I took it into my local AT&T store and they found the IMEI was listed as the old phone, and corrected it. Of course, my phone worked perfectly in the store, even before the IMEI change. I figured that was the problem though, and it actually seemed to work for the rest of the day, but the next morning it was back to a weak signal.
At this point I guess I'll return it, and try another one, but I figured I'd check here and see if there was a better solution.
Hi,
From past three days, signal is not showing up on the phone. And it only shows a red triangle with a white plus sign on it.(Emergency Calls Only)
I didnt do any changes to the phone, it just randomly started three days ago.
I am on Indian version of unlocked Motorola atrix 2 MB865.
I am on jellybean 4.1.2 for past many months. So I dont suspect the ROM.
I have tried using some other sims also.(It is NOT the problem of the Sim)
I usually get full signal at my place.
I have searched internet thoroughly and read almost all the threads related to this topic, but it didnt help me much.
Things I have tried till now.-->
- Swapped sims with many other phones.
- Installed the "Network" app and many other similar apps which was suggested in some other threads.
- Switched Flight mode on and off.
- Factory reset the phone.
- Kept it off for hours and then checked again.
- Prayed that it will get fixed soon
Q) Did you try turning it off and on again?
Ans) Yes..yes.. Many many times. Sometimes, after reboot it shows signal for 2-5 minutes, but I CANT make/receive any calls/sms(The call just drops two seconds after dialling)
PS:- I think that when I received the last call, I was listening music on my headset and I had received the call with the headset.
Thank You very much.

I have now found that it is due to very very poor reception.... For some reason, this phone's signal reception has drastically reduced.
I can get signal only if I go out, still the signal strength is shown at maximum -75dB and frequently dropping to -100dB. I was able to make one call and it dropped as soon as i entered inside the house.
(The same sim on other phones have full range even inside house)
What is the suggested solution?
Thanks

Seems to be a hardware issue then. Is your phone within warranty, by chance?
Nop it is not in warranty.

If you can't afford to help, then what's the point of this post?
Increasing post count I guess.
Might be a loose connection after a drop ?
Your best bet would be to dissamble the phone and assemble again. In the meantime check the connectors and others if they're in their place. There're good disassembly videos for atrix 2 in youtube.

K s h i t i j s, who is your network provider? EDIT: Just saw that you're on MTNL.
I have been having a similar problem for a similar length of time with my Atrix 2 and I'm on stock ICS. I got my sim replaced by Vodafone but the problem persisted so I asked the guy who originally sold it to me to get it checked out (warranty is long gone).
He mentioned that another customer of his with the same phone also developed the same problem around November or December 2013. Both that guy and I are on Vodafone, Mumbai.
In testing, his phone worked perfectly with an Airtel sim and mine worked perfectly with a borrowed IDEA sim. Both our sims work perfectly in other phones. Both were then sent to the official service centre but they essentially threw their hands up.
The coincidental timing of the problem for two (maybe three) phones of the same model leads one to think there must something with the network broadcasting? Could someone with better knowledge of the subject (mine is approximately nil) comment?
Folks,
I am curious if anyone else is having some of the issues I've been experiencing. I am not happy with this phone overall. I am having lots of problems with it:
- HotSpot - I originally found a hotspot issue with this phone, that took them a few weeks to resolve. But even after they've resolved it, I have other issues. The biggest is that after some period of time, my laptop will not get data through the phone. I've tried different laptops. The laptop shows that it is still connected to the phone's wifi but no data. The fix is to disconnect the laptop from the hotspot and then reconnect. This is an issue for me as I use this for work to provide customer demos. In order to get to my lab, I need to make 2 VPN hops. (1 into work and then 1 into my lab) When I disconnect and reconnect my laptop the hotspot, I have to go through all of that again. This problem only affects the connected device. So when the laptop stops "working", the phone can send/receive data just fine. If I kick off a speedtest, it looks good.
- GPS issues - The GPS accuracy seems to drift. Lots of times when I am using Waze, it has me in completely different places going in different directions.
- Phone issues - I drop calls often. I believe (but not 100% sure) that this happens when it uses wi-fi calling. (I just turned off wifi calling, so I'll see how it goes)
- Phone issues pt. 2 - Sometimes I get an error message "Mobile network is unavailable" and I cannot make or receive calls. A reboot fixes this.
Been a huge LG phone fan since the G2 (even loved the G4 despite the bootlooping), but this phone makes me want to throw it against the wall
Hello! You may want to turn off the default 5 minutes timeout. I think this is the problem. Check attached screenshots.

It's not turning off as I have the timeout set to Never Turns Off.

I am having the same issue. People have told me that they tried to call me but phone never rang. It also rang on their end and then went to VM. So people assume that I got a missed call but I didn't.
I also at time show no reception. I would have to go into auto connection to network and then it starts working again.
This is really screwing up my business.
I have the same problem with missing calls (never rings) or I can't make a call. Also, sometimes I can hear the other person clearly but they can't hear me or I sound terrible on their end. However, I have an LG V30 (lurking here because I'm looking to buy a V50) so I don't think it has to do with the phone as much as it's Verizon's coverage. For the last 8+ months this issue has gotten worse in my area. I was thinking it was the phone, but I think it's Verizon.
Edit: Just in case it matters, I'm still on the original grandfathered UDP
I must clarify that this issue only pertains when I am home. For some reason, when I loose Verizon connection because the wifi is being used or a dead spot in my house. The mobile connection won't come back on until I manuallly have to reconnect.
I used to have Verizon fios at home and never had issues before but as soon as i switched to optimum this issue might be because of that.
Outside of my home, I don't have any issues with missed calls.
