Echo During Calls on Tmobile US - Nexus S Q&A, Help & Troubleshooting

Recently it's come to my attention that whoever calls my Nexus S hears an echo of themselves during the call. This happens on every call from any network/landlines. I can't hear any problems on my end. It also doesn't matter what tower I'm connected to. Any ideas on what could fix this?
Running stock Jellybean.
Sent from my LT26i

So I've been trying some different kernels and radios, and it doesn't seem to ever go away completely. However, running Simple Kernel 1.4 (with voodoo) and the KF1 radio seems to work the best. I'll test it for a few days and see if there's any more issues.
Really not wanting to switch to my backup phone (MyTouch 4G).

[Q] Anyone else having this problem?

I recently flashed the stock rom that is rooted with hsupa and sideloading enabled onto my Inspire, and over the last 2 days I've noticed that sometimes when I try to make a call, my phone just hangs up. It's weird, because text and data works perfectly fine, it's only when I make phone calls. Anyone else notice this problem with a rooted rom, stock or not?

Yep, happens to me all the time. Internet doesn't always work either. I "fixed" the problem by setting it to GSM only mode. Now I only have EDGE internet.

Are you on the same rooted stock rom, or something different? I don't seem to remember having this problem when I was just on pure stock AT&T with no root. Somewhat annoying, as I'll have to place a call 3 or 4 times to get it to go through, but what's really annoying is that it is so sporadic I can't gauge when it'll happen!

I've noticed this at multiple times, but haven't been able to narrow down what's causing it. I was running Revolution 1.15, and I think it started when I applied the .16 performance patch. It got so bad last night I couldn't make/receive calls for hours. I did a full wipe an reinstalled 1.15 and all has been well the last 24 hours. I just flashed the 2.1 patch but we'll see what happens. Note: Not only can you not make calls when this is happening you won't be able to receive calls either. It does appear to most often happen when bouncing between networks (HSDPA, UMTS, Edge, etc)

Man, I'm glad I'm not the only one having this problem. I thought my phone was defective at first, and now I don't feel so crazy anymore. My sister was furious with me, I had to pick her and her boyfriend up from DIA yesterday to take her to Copper Mountain to snowboard with my girlfriend and myself, and she called me 4 times and I didn't receive a single one. I wonder if it has anything to do with HSUPA being enabled on the phones, but at this point I'm just ready to give up root and go back to stock. I don't make tons of calls, but I'd like to be able to when I need to, and for my phone to not hang up on me in the middle of one. I have noticed though it's particularly bad for me when I'm on bluetooth.
I was also having those problems
I am using Revolution 4G 2.1. I'm in the process of trying to get the problem figured out. Stock rooted rom had problems for me because you couldn't set it to GSM only, and that's the only way I've found to make the phone reliably work as a phone.
If anyone can figure it out, I'd love to know what causes it. I've been poking around myself, but haven't come up with anything worthwhile. I suppose I'll flash a different rom and try that.

Anyone found any clue as to why this happens? I've searched the dev forums but nobody seems to mention this, which makes me wonder if most people have this problem.

I have never had this problem. Running a rooted stocker.

It happened to me again last night. Still had data but lost the ability to make/receive calls. I switched network to GSM only, the data switched to EDGE, and i was able to make/recieve calls. Turned back to GSM/WCDMA, no calls. Rebooted, no calls. Turned back to GSM only, calling functionality returned. I did another full wipe, installed AR 2.1, sound fix, apache 1.6 kernel, and calling is restored when connected to HSDPA/WCDMA. Has been working fine for the last 12 hours. I'll keep you updated. I don't know why it's doing this, and it doesn't make sense as to why a wipe would fix it. The first time this happened I was runing the stock radio. Last night when it happened i was running the recommended radio in the AR thread (M2). I've now switched back to stock this time...let's see what happens
Edit: I am also glad to know I'm not the only one having these issues...maybe someone a LOT smarter than I am can figure it out. It's annoying to have to have a slow data connection to have a reliable voice connection. The last Android I had (LG GW620 Eve), also did this from time to time, but I just blamed it on the fact that it was a POS. My voicemail actually went like this "This is Greg. I probably have no idea you called me just now, so please leave a message and I'll get back to you"
Edit: mike1986 (android revolution developer) just chimed in in his thread and stated these issues should be fixed in version 3.0 set to be released soon. Is anyone else that's having these problems NOT running Revolution?

I had this problem when I first rooted (running Inspire 4G Stock Rom w/Root, HSUPA, and Sideloading from the development section) I installed Android Revolution 2.1 and it went away.
I know from my captivate days that sometimes a ROM just hiccups and a fresh flash can fix the issues. I don't know if this is the same with HTC, but it's all android so It's plausible.

[Q] Weird speakerphone issue?

I've been using my phone recently, and I just noticed that whenever I talk on the phone, whether or not I had speakerphone selected during the phone call, the sound comes through the speaker.
Has anyone experienced this? Is there any way to fix it? I'm in KD1 deodexed and rooted with Bali kernel uv.
I have had this issue once. Never again, and I didnt to anything to resolve it. I simply floored the phone over (screen facing away from face) and proceeded with the call! If I rememder correctly I was on wifi calling and it was received while in another application (not sure which one). Since it only happened once I just wrote it off. Is it constant for you? What are you doing on your phone when it happens? receiving calls? out going calls? All calls? Are you accessing other apps? More info would be great.
On the moon our weekends are so advanced they encompass the entire week
Its the Ball kernel and wifi calling. Shut off your wifi and the problem disappears.
Sent from my SGH-T959V using Tapatalk
So it's the Bali kernel...I've since given the phone to another family member who just uses it as a...phone lol. Can I put the stock kernel back on it because he needs both wifi calling and the calling to not go through speakerphone..

[Q] What would cause a ticking static on my cellphone's speaker every other call?

My phone is giving a loud ticking static noise when I call people (I hear it on my end, don't know if people hear it on their end)
It happens every other call.
I'm on Infused 1.5.0 and the gtg's community kernel that comes with that rom (I'm assuming that is the kernel that comes with infused anyway).
Any solutions besides trying to flash back to stock or flash a different rom or something to see if it happens there?
edit: ok, friend's phone who is also on at&t (but is an iphone) is having the same issue. Probably the tower being dumb. We did have a thunderstorm earlier.
Definitely a network issue, if it didn't stop, I'd report it to AT&T

[Q] NS i9020 weird call issue

Hello,
I've been a user of the xda ROMs for quite some time and i appreaciate all the work that's been put into the community.
Sadly, i have stumbled onto an issue i cannot solve myself, so i am seeking your help.
Description: When receiving a call and answering it (phone vibrates and rings), i cannot hear the other person, but they can hear me. (Speaker on/off doesn't do a thing, volume rocker up/down either). If the person calls back within a few minutes, i can almost always hear them and have a normal conversation. This does not happen in 100% of the cases, but in more than 50%. I have switched ROMs, kernels and radios (ATM i have CM7.1 RC, mar1x bfs v4,5, and XXKB3)
Is there any hope?
same issue on i9020t
I been having the same issue, but not quite as frequent, on my I9020T. I've experienced it with Cyanogenmod 7.1RC1 and NSCOLLAB (also based on CM71). I think I had it with CM7.0.2 and CM7.0.3, but can't remember for sure. The problem does not occur when I revert back to stock 2.3.4 rooted.
A somewhat related post in this forum, http://forum.xda-developers.com/showthread.php?t=1188264, got me thinking. The OP had a similar problem on an I9023 when bluetooth was enabled. I've noticed on NSCOLLAB that DSPManager is running a "Headset" service. I do not have DSPManager installed on my stock install.
Can someone more knowledgeable tell if its possible this service could be related to the problem with callers not being able to hear me. FYI, my bluetooth is normally off and I don't use a headset. I'm back to running NSCOLLAB 1.3.8, but I've disabled the Headset service. If the problem doesn't occur for a couple days, I think I may have something.
dinuvali, is the Headset service running on your build?
Removed DSPManager earlier. Just answered a call where they hear me but I can't hear them. They called me back, all normal.
Oh well, rolling back to stock for now.
Sent from my Nexus S using XDA App
Thank you for the reply,
Yes my CM 7.1 is running the DSPManager service.
Also, my neighbour who has the exact device as me, but stock unrooted, has never experienced this problem.
Along with this problem of not hearing the other person on the first call, i also get the dropped call once in a while (not only after 3 mins of talking, but also while the phone is ringing and they still haven't picked up yet)
From all the posts i've read concerning this issue, i think it's mainly a hardware issue, but maybe it can be bypassed with some sort of tweak.
Major breakthrough imo
Pressing Hold (left upper corner) and then unholding will render me able to hear the other person!

Great find! Come to think of it, I never had it happen when I answered someone and immediately hit speakerphone, something I do alot when in my car mount.
I think I'll reload NSCollab, new version just came out today. When it happens again (unless they fixed it) I'll try this out. Thanks!

Weird Issue Call Drop using custom ROMS In the Middle of Conversation

I have the strangest issue. I get disconnected from calls in the middle of conversation if I'm using any of these main custom ROMs.
Blaz3r
CyanogenMod 10
Blaze Tweaked ICS 2.2
But If I'm using a stock ICS ROM or "Android ICS 4.0.4 UVLH5 (Posted by tthaz777)" everything is very stable and no disconnects.
I have full bar with all the ROMs and get perfect data speed and everything else works fine. I'm using the same exact apps on the ROMs as I do on the stock, so I don't think it's related to a particular app. It seems as if TMobile scans the sessions at their network level and disconnects the call because my connection is not providing some information/call data they need. The disconnect can happen as fast as a few seconds or after a 10 minutes or so, just random.
Is anyone else experiencing this ?
I'm currently running below and everything is stable with no drop calls. Just can't figure out why this happens when install any other ROM. and Yes I always to do a full wipe before install.
Android ICS 4.0.4 UVLH5 (Posted by tthaz777) with merwin's scorched-kernel-t769-ics v1.0.29
Well the 4.0.4 thazz build should be pretty stable as its essentially stock. That being said my wife (who is INCREDIBLY picky on how her phone functions... I've yet to get her to try something not TW-based) has been using Tweaked since before it was even posted and uses her phone as a phone constantly (... lot's of out-of-state sisters that she's always yapping with) and has yet to report an issue. I am unclear why you would be having these issues with the particular specificity you are experiencing... especially if kernels are remaining consistent across TW-based builds anyway. Without me being able to recreate it on my end or a logcat taken during the premature disconnect on your end I'm at a loss. If nothing else, at least you found something that works for you, so I suppose it a could be worse.
Sorry for the troubles.
Not all stock apps or play store apps work with 4.1, I had the same problem when I let my battery app manage my data. It would wait to connect sometimes up to 20-30 secs later after waking to make a call. Check all your apps your using for compatibility, and when you wake your phone give it a sec before calling out. If your in a bad area the alternating of edge/3g/HSDPA+ doesn't help either. I stopped allowing my battery app data control and that solved 90% of my issues, sometimes it still does it but only when I'm in the boonies.

LOL I am using T-Mobile service with this device, so if that's the case for you I would expect a few drops from time to time
On a serious note, drops can happen with full bars for a variety of reasons. Tower is overloaded (signal shows strong but can't connect/gets dropped), person you have called drops you (calling someone in NY that has AT&T? ), bad/faulty sim card (free to get checked and replaced), etc. No cell phone/ROM is drop call immune, even stock (and yes even those people using Verizon). FWIW, I haven't dropped a single call in over a month using Thomas' PA and Tweaked. That's pretty good considering that's including the holidays and I didn't go home this year.
Thanks for the replies guys. What drives me crazy is that I have absolutely no dropped calls when using the stock ICS ROM, but as soon as I load any of the ICS ROMs mentioned the voice call gets disconnected periodically. Same Location, Same Apps, Same Calling Number, nothing changes except the ROM.
I'm fairly technical and good at troubleshooting but not an expert in reading the Android Logcat and don't know what to look for in the log. I have loaded the UVLH5 radio after flashing the the custom ROMs to see if that might be the cause but same thing.... I wondering if I need to try an older Radio...
Like I said all is running great with Android ICS 4.0.4 UVLH5 (by tthaz777) + merwin's scorched-kernel-t769-ics v1.0.29 OC to 1728 but not knowing what's causing the drops is just driving me crazy....
To test I just load the ROM and then call one of the free news numbers (ABC News etc 650-293-9114) and put the phone on speakerphone, and yes I have tried varies other numbers... JUST WEIRD
Try finding an app of the app store to make logging easier like logcat or something. Then run the app and make a call. If it doesnt disconnect, restart the log. When it does disconnect, end the log and copy+paste it here. That is the only real way to find out whats up.
So the problem started again this AM and it's been fine since I flashed Android ICS 4.0.4 UVLH5 (by tthaz777). I hear the hang up tone and calls would just disconnect in the middle of conversation with perfect signal strength. Nothing new was added to the phone, so only way to fix it was to reflash it again from a nan backup.
This is driving me crazy. Attached is a short logcat from right before the call dropped, could one of you experts check it out and tell me if you see anything strange going on....
Thanks

any chance you can put that on pastebin instead of a pdf? just post a link to it. It could be helpful to a dev as I see that some info is spread out to different pages and is cut off.
Also did you use an existing sim from a previous phone when getting this phone or did you get a brand new sim? I know various issues arise when using an old sim with this phone. My old sim had issues and wouldn't connect to wifi calling and it was only 10 months old.

When I initially had the issue I ordered a new sim hoping it would resolved it and that didn't help, so I flashed ICS 4.0.4 UVLH5 (by tthaz777) which is pretty much the stock with bloatware removed and that resolved the problem and not a single dropped call for a month and it just started again. It's so weird as if Mobile is looking for something in the connection/session and forces a disconnect.

Ordering a new sim doesn't mean getting a compatible sim. Have you taken the phone to a Tmo store and had someone check it out? They could've sent you another partially compatible sim for it. If I knew more about reading the logs I would love to help you out....
