anyone else hearing interference during calls? - Samsung Galaxy Nexus

Hi. I have the volume bug and not sure if this is related but i've noticed that I can hear interference during voice calls very faintly in the background. I'm on Vodafone and have only noticed this at home where I only get 2g coverage. I have WiFi on but dont know if thay makes a difference.
Anyone else hearing anything during calls? It's the classic cellular noises a bit like the built in radiation ringtone.

If you use wifi at home for data connection you could try the following thing.
2G gives trouble as you know...
In the phone application type *#*#4636#*#* touch phone information, set it to WCDMA only and see what happens and if it gets better with calls, maybe you lose the complete data connection and you have to put it back on where it was, I disconnects de the radio for a couple of seconds when it reconnects to the provider )
This forces not to use 2G networks, so there is no interference of this source.
Maybe it helps? it's just a thought

This will not fix anything especially as he specifically stated that he only gets 2G coverage at home

also, as I have already pointed out in another thread, that option does not stay persistent (at least in my experience)

For all those people who are saying that you can force the phone into 3G only mode - I have some news for you -
It doesn't stick.
Try it yourself.
1. Go to the phone application
2. Hit *#*#4636#*#*
3. Select Phone Information
4. Scroll down until you find Set preferred network type
5. Change it to WDCDMA only (or indeed anything other than GSM/CDMA Auto PRL)
6. Now reboot your phone
It doesn't stay persistent.

But you don't make phonecalls over 2G are you, if you're on 900Mhz provider this will use gsm signal to make calls isn't it?

you are incorrect - if your phone is in 2G mode (either due to forcing it into 2G mode via the settings option, or by being in a non-3G coverage area) all communications are done over 2G. This includes SMS, cellular calls, and mobile data access.

Ok, did not know this, and wanted to know.
Is this the case everywhere or a standard in mobile communications technology?
So no chance that GSM signal is stil there and works if you don't get 2G data connection?
Did not see my GSM signal drop out when 2G was available.

If you can only receive 2G connection in your coverage area, you will not be able to make calls over 3G.

Hey so has anyone else noticed this issue? As I mentioned, it's very very faint - as in you have to be in an otherwise silent room to notice. And it occurs when I have 3G too i've noticed today.
Some more detail:
The noise doesn't start as soon as the phone connects - usually a few seconds afterwards and it actually continues for a couple of seconds after i've hung up (which I've noticed if I put the phone straight back up to my ear).
Would someone else mind doing a test call in a very quiet place and letting me know?

Hi guys sorry to bump this but quite concerned that it's only my phone this is happening to. If someone wouldn't mind just listening carefully during a call (maybe to your voicemail to avoid the weirdness!) in a quiet room to let me know if they can hear interference that would be great.

So this problem frustrated me so much that I got the phone exchanged. Guess what though - same problem.
Surely someone else has noticed this - if you're in a quiet place it's both pretty loud and very distracting.
As I originally explained - after a few seconds of any call, I get a very short mute (we're talking microseconds) followed by the kind of background buzzing noise you get when you put a phone near a speaker.
Could it be down to a faulty batch?

new HTC user here having a weird problem

hey guys
ok so i have the TP2 running WM 6.5 professional
ROM 1.86.401.0 (67102) WWE
ROM date 25/9/2009
radio 4.49.25.17
protocol ver. 61.44tc.25.32U
my service provider is Etisalat in the UAE
the problem that im having is that when i set the BAND to AUTO, it picked up the the 3G network...but problem is that it keep shuffling between 3G and EDGE. because of that it wont recieve calls. one fix i was told was to manually select GSM BAND. the call problem was solved because of that.
but since i have done this, i been having another porblem. after using internet to say update the weather tab, i cant make or recieve call, or send sms or anything. everytime i use internet on the TP2, i have to switch to AIRPLANE MODE and then back to PHONE its driving me nuts
anyone facing the same problem? or has a fix to this?
Switching between 3G and Edge is normal, because not everywhere you have good service.
But just to make sure:
When you set band to AUTO and you are switching between 3G and Edge, can you call someone?
I had problems with my HTC Kaiser in the UAE. Etisalat and Du told me they only can provide mobile internet to BlackBerries and IPhones...
yeah, when it is switching between 3G and Edge, i cant make calls and i cant recieve calls either. they say my cell if off while its actually on

Go into the Bands page (where you manually select the bands). Press "WCDMA" to enable 3G only. That will keep you in 3G, but if you go into a non-3G area, you won't get any signal at all.
EDGE can only handle one thing at a time. If you don't have an active data connection, you can use the phone (call, SMS). If data connection is active, you can't use the phone functions. So, if you're on a webpage and someone calls you, their call won't go through.
3G allows you to use phone functions and data at the same time. So if you're on a web page and someone calls you, you can answer it.
ok that was surprisingly simple.. thanks
Edge can only handle one thing at a time? I routinely get and make calls and browse at the same time (or get emails via active outlook push connections, etc). And this is both when I'm in Edge areas (eg when I go to my cabin in Montana (heck - ANYWHERE west of Milwaukee) or when I have 3G (around here).
This does, however, appear to be a feature strictly of AT&T. But I don't believe the inability to do simultaneous data and call is a hardware or even Edge technology limitation - I believe its a network specific limitation.
Having said that, my money would be on an incorrect radio or DLL hanging around in the phone...
(Standard disclaimer: I know nothing about non-US carriers or their oddities. I reserve the right to be wrong- a right I exercise somewhat frequently )
well i upgraded to WM6.5 so the radio is the one that came with the upgrade.nothing else has been changed.
have a feeling the problem is with the phone as my pervious phone, sony ericsson's P990i had absolutely no porblems switching from data to call and back to data without having to do anything.
one thing i noted is that once i start an internet session, it keeps running unless i turn the switch to airplane mode to force a connection break.

Simultaneous call and data

Just started using my Desire last night! Feeling good.
However...
Was just on a call, tried to use the Android Marketplace. Couldn't.
Got curious, and tried to use Google Maps mid call. Couldn't.
Tried to use the internet during the call. Couldn't.
Now, I'm on T-Mobile (UK) and have just come from a Nokia E71. With my E71 I could make a call and use Google Maps.
Am I missing something or is this bit of multitasking somehow not possible???
Please tell me I'm missing something!

A lot of carriers don't currently support simultaneous data and voice. For example, I have Sprint and it has no support for this - very annoying.
AT&T is the only one I'm personally aware that supports both talking and using data at the same time.
If it doesn't work for you, you're out of luck with your carrier.

Sprint is a CDMA network, and most CDMA networks don't currently support simultaneous voice and data.
Most GSM networks do support this when you have a 3G connection. The voice call is routed over 2G and the data over 3G. If your data connection drops down to GPRS or EDGE, you will lose data connectivity because most networks do not support simultaneous voice and data over 2G, though I'm told that they can be set up to do so, so I guess it's more down to bandwidth.
Regards,
Dave
I know that Sprint's CDMA has an issue with simultaneous data and voice. Which suck. And I know they are making good attempts to sort this out for the EVO, which is good.
But again, I've been doing this fine on my E71. The only thing I can think of, in relation to Dave's comments, is that for some reason, because the Desire can suck up more data, T-mobile have restricted it. Which would suprise me because, as Dave said, simultaneous voice and data is a feature of most GSM networks and has been for a while.
I have just tested that and it's true - the phone doesn't have simultaneous data and voice connection
Now normally I don't need that because if I talk, I talk and not browse the web, but even my freaking G1 could do both things at the same time. What the heck? It must be something HTC did.
One more reason to eagerly wait for root...
I don't see how this is a big deal. Why would you need to make a call AND browse the market place or look at maps etc? Surely it's something that can be done after the call even if it is receiving directions or whatever.

It's a big deal because:
1. HTC (or T-Mobile) has obviously done something to disable it because Android with GSM should have such functionality;
2. Older Android phones and even some "dumbphones" have that functionality
3. No point in browsing market while talking, but what about looking up maps while talking? - That was even one of G1's selling points.
I have often been on a call and used the internet or searched Maps. So it's something that I am quite used to doing.
Though I thought I'd get an answer straight from the horses mouth and have emailed HTC support just now. I'm hoping they give me good news...
False alarm. This only happens on GPRS, which is normal. Simultaneous data and voice connection can only happen on 3G as explained in Android Forums.
and of course correctly explained by Dave in post #3 here.

Kind of tired of explaining this one but here are the 2 use cases:
- you're talking with someone on the phone and they ask you for directions, look something up on the internet, see if you received their email, etc, etc
- and even more importantly, when my rooted phone acts as a WiFi access point with android-wifi-tether and someone calls me, my freaking Inet disappears until I'm off the phone. This is the more annoying of the 2 use cases.
Well, this was their reply:
"If you start the call being connected through 2G, then yes the internet will then work. But as soon as the signal goes over to 3G then the internet connection and usuage will be turned off.
When it comes to wifi, if you are in a call and you are connected to wifi, then you should be able to surf.
Hope this answers your questions.
Thank you for contacting HTC. "
I did get concerned for a second. I've just tried the wifi and call which worked. And I just tried a call again, with wifi turned off and it worked, even though it didn't work before.
I just hope it routes voice and data in a way that doesn't trip me up in the future. I.e. voice over 2G if I'm trying to access data.
So yes, false alarm.
And funnily enough I just now got a call from Carphonewarehouse asking me if I'm having a problem sending texts as some Desires do indeed have a software fault where they have no Service Centre number for messages. For once, I've skipped the faulty units!
Cheers guys. Sorry scare anyone.
lol.
Whoever it was at HTC got their 2G and 3G mixed up.
what they meant to say was if it goes down to 2G then it'll stop.
You'll be ok in general, as long as you have 3G signal wherever you are. If you've only got 2G, you'll have to hang up, find out and then call back!
the SMSC shouldn't be a problem though, just program it in manually. Not worth sending a phone back for unless it fails then as well.
Even if I'm on 3G/HSPA, when I call someone, as soon as the call is connected, my data connection disappears (only shows bars, no G, 3G, or H) and I can't browse the web or use maps while in-call :-/
ok, well that's not right. The bars should only disappear if you turn the mobile data off. it should not get turned off by a call. Even if i try it when in G, the bars stay showing, just no data comes till i hang up the call.
If the bars are disappearing, something else is going on.
It could be a local network issue. maybe it's an old transmitter that missed an update or something...?could possibly be a full tower.
I know that a few years ago, the towers would kick off data connections to allow more airtime for voice calls which have priority, but i don't know if that's still relevant on 3G.
This was a hot discussion back when the Hero came out as well.
In the end I think it comes down to the network of your carrier. Some people report they can internet and call at the same time. Others say when they are internetting on their phone, a call is directly forwarded to their voicemail etc.
I'm afraid it's a combination between how your carrier configures their network and on what connection you are on (3g, 2g etc).
Yeah it's false alarm no #2 -- must be a spotty 3G at my house. I went to the city centre and tried it there -- worked like a charm.
Though it's a bit weird as 3G speed is not bad at all at my house, but when I call, data connection goes off :-/
Maybe at the city center you got more cells in range than in your house. Means your carrier got more available bandwith
I think reception gets spotty. Sometimes voice and data works, sometimes it doesn't. At home in my bedroom I can get H connection, 20 meters away I can't.
I think the important thing is that the phone is capable. The rest is just pinning down exactly the situation that we want to avoid.

Radio sleeping possibly?

So periodically my phone is active and working... all of a sudden i have full strength in bars but I can not transmit a call, recieve a call or use data and anyone calling will automatically goto voicemail. I'm beyond mind boggled what in the world is happening.
Im using wind mobile as my phone carrier and using UKID as the baseband.
Would appreciate any help or support.
same thing is happening to my phone.
I can not transmit a call, recieve a call (some times)
Im using 2.3.6 official rom.
Anyone know anything about
it was once happened to me as well. That was because of poor reception area. What I did was to manually search and select the network provider instead of automatic selection, this pretty much solved my issue in that area. Give it a go and share your result. Also restart your phone once before doing this.
Very odd.
Tried the above and still facing the same issue.
Pulled battery and sim card to be safe for a minute. turn on phone and went and did manual search. will have running service for about 5 minutes or so and the poof... doesnt exist.

I have middle signal strength -89dbm

Better cell network mode management

The tmobile service in my area sucks and it will stay on 4g lte even when I have a very bad connection which drops calls and gives me really bad speeds. Is there an app that will automatically switch lte/gsm/wcdma when the signal is very low so I wont drop calls, waste battery and give me poor dl speeds? Or is there anything else that I can do? Maybe with tasker or a tweak. I would appreciate any type of solution. Thank you.
Is there any thing I can do about this?
On stock Rom go to settings>more networks>mobile networks>network mode.
Pick the one you want. Probably gsm/wcdma auto connect.

Thank you for your reply. I already know about that option. I still want to have access to lte when I have a decent connection. Is there an app or a tasker configuration that if the signal is below a certain level it will switch networks? Also, which network it used to make phone calls? I thought all of them but my friend said phone calls are made on 2g. Thank you!

Is there any solution for this? Also when you are connected to lte are you still making phone calls through 2g? Thanks.
Is this a problem near your home? Can you use wifi calling to help fix the dropped calls? Not sure about how to get the phone to switch from LTE to 4G when the connection is poor. I do it manually right now because my LTE has been acting a little wonky lately where it won't even connect to LTE and leaves my phone in network limbo unless I force it to use 4G. I'd like to see a solution to the LTE - 4G switching too.
Last i recall, there is no tasker or app capable of doing such a thing like switching network preferences. It goes against "policy" per say. But your friend is right about calls being made through 2g. That is how you are able to use data whilst on a phone call. The data is being used through 3G and up, while the call is being used on 2G. now i am not sure about T-Mobile's "HD Voice" calling, that is prolly LTE.
I myself have looked through every single API google has trying to write my own app to change the network preferences and could not find it. There may be an option through root though. Havent found it yet.
Correct.
Calls - 2G
Data - 3G+
TM HD - New LTE Network.

service lost every so often

hey all,
I have att on my fire phone , and every now then(atleast once a day) I lose service. It would say searching on the signal bar and it never finds it lol. I would have to restart the phone and then it reverts back to normal. is anyone else having this issue?
I'm guessing it's the fact that LTE has lower signal quality than 3G and
once you force the phone to 3G (once per reboot) it will never disconnect.
LTE is used only for data, when you make calls it will switch to 3G anyways,
so call your phone while it's in LTE and you should notice signal improve ...
To switch do this:
Same as dialing *#*#4636#*#* but this is easier to use:
play.google.com /store/apps/details?id=diewland.testing.phone
Go under Phone Info, then select 3G auto I believe, 4th down from top.
Also, contact Amazon support (right from help on your phone) if the above fixes it.
Tell them you want settings for disabling LTE added to the phone,- I did that and they
said they've submitted to developers, but I guess it's best if more people request this ...
