hello,
i'm using the following version of the LG G2 ;
Android Version : 4.4.2
Band base: M8974-AAAANAZM-1.0.190084
kernel Version : 3.4.0
Build Number :KOT491.D80220a
Sofware Version : D80220a-HKG-XX
and each time i'm having a phone call, i'm loosing the Data Connection (3G or 3G+ or Edge )
What would you recommend to fix this (annoying because i can't use waze for example while having a phone call with bluetooth in my car)
Many thanks for your help

Err .. That's normal, and I'm pretty sure it happens with almost all phones and network providers. Your Data Connection will cut out if you make or receive a phone call. Nohting to do with your phone. Use wifi if you want to maintain a connection.

I think any phone with 2 radios can do it just fine. I'm not sure I've tried with the g2, but my gnex and even thunderbolt could, both on vzw. att phones had this ability for years before lte (and the second radio it required) provided it for Verizon. att even ran iPhone commercials pointing this out, since the 3g vzw iPhone only had one radio and couldn't talk and use data simultaneously.

Yeah I agree, a second radio would be required .. which could be why it worked with your Sensation. Unfortunately I don't think any phones over here in the UK have 2 radios as I have had this issues wih ALL of my phones. It's the norm over here.

I believe, but may be mistaken, that the VZW, ATT, and TMo flavors all have 2 radios while the Sprint G2 does not, as their new Spark network combines voice and data onto one radio. This is what I've gathered from reading other forums but have no concrete proof. I believe I once talked on my G2 while using the GPS when driving, which would obviously require data.
What provider is the OP on? Looks like he has a D802, which is the INT model, right?
...this is normal behavior but only in 2G (Edge)...

It is normal in 2G (GPRS or EDGE) to loose data connection during a call...this is the GSM standard...3G is a different standard, it supposed to keep the data connection during a call - voice data is CS (circuit switch, a GSM stadard call), data connection is PS (packet switch, different circuit in phone).
All 3G phones have similar build so CS and PS are completely separate - if you are still losing data connection during a call could be a network issue, not a phone issue.
In 4G is a different situation, at least for the moment - this is still in development, the voice is still in 2G or 3G, not in 4G.

Sprints LTE on phones prior to tri-band had no issues with simultaneous data/calls. The implementation of these tri-band phones has changed the protocol used. They now use CSFB (circuit switched fallback) and this requires the phone to fallback from LTE when a call is made or received. This prevents any data to transmit during a call.

I know, I red about on the net - as I am living in Europe I don't have this problem - from the begining the European providers used CSFB and eCSFB (they are trying now to develop VoLTE, this is the next step) - I was talking about VOLDOR issue - he mentioned about some problems in 2G and 3G, not in LTE...on another hand he has a GSM+LTE version of the phone, not CDMA+LTE (Sprint) - Sofware Version : D80220a-HKG-XX (Hong Kong - http://www.lg.com/hk_en/mobile-phones/lg-D802)
Sorry, but i'm still a bit lost : Am i having the issue because i have an Hong Kong Version of the phone ? is it an hardware limitation ? Should i try a Europeean ROM Version (i'm living in France, and without changing of provider it was working on my previous HTC Sensation)
I have this issue too. Works fine on my HTC One M7, but when I use the simcard in the verizon G2, no data.
I used LTE Discovery - turns out that when you're connected the LTE and call out, the G2 starts the call on 2G. My M7 starts the call on 3G or H, so I have data and voice on my M7. I am looking for a way to fix this too...

Hi everyone
I'm using Singtel ROM version 1.31.871.14 with Radio version 1.58.16.27, and I have complaints from people who said they called me but I never see a missed call on my Touch Dual device.
Did anyone suffer same problem?
Do I need to update the ROM or Radio version ? if yes, which version should I use ?
try this changing your network type to GSM
settings > phone > band
when your device is online with gprs you will not receive calls.
changing to gsm will make it worse...
I have a same problem.
Here in my house where I should have full reception, I have only 2 lines and it falls to 0 from time to time.
Does anyone know anything about it? Is it radio rom problem or?
I also would like to know which radio rom gives the best reception - if not the default one delivered onto your phone.
My info - T-Mobile branded HTC Touch Dual (named Touch Plus by T-Mobile).
Operator - T-Mobile
Country - Netherlands.
Very poor reception, also when only GSM Band selected. Phone is now in for repair by T-Mobile - i think it has an antenna problem but could not get my finger at it.
Anyone any info to lighten things up ?
Would be highly appr.

I don't believe that the above is correct. As far as I am aware, calls are independent from data. I have GPRS connected all of the time, and can still send and receive calls.
Data and calling use and not independant - when you make a call notice that your GPRS/HSDPA connection drops and then restarts when you end the call. Texts are not affected as you can send/receive texts in mid-call as well as during a data connection.
Hi,
after having several missed calls going straight to my answering machine on my new HTC Hero. I was getting a bit paranoiac, so I've decided to test in/out calls.
Basically, 90 of my incoming calls were going straight to my answering machine. Out-call were about 30% KO
After several tests, to make sure there was a problem, I've decided to request for support from HTC.
Support told me that I should shut the 3g connection every time I would want to receive a call .
So I tried and Bingo, if 3G is activated, I get 10% of the calls, if I deactivate it 90% success.
So you'll say, I should be happy? Right? Wrong!
The main use of that kind of phone is to have a data integration, otherwise I would have kept my old nokia from 10 years ago..
Here basically, if I follow HTC idea, I should keep the 3g closed, sometime, I should switch it on to get my mails, thanks to the non true push capacities (ok this one is not htc) then wait for the sync, maybe force it , get my mails, and then, shut 3g back and pray that no Über important call would have been done.
Well that plain sucks!
Never had such a thing on my previous Data friendly mobiles, why should I accept it on the Hero?
If someone have come across this bug, cause it is a bug, how did he/she managed to fix it?
Thanks
works fine on mine....i suggest you are on a ****e network, or on only 2G where you are. that's what usually causes this.
I guess they suggested this because it sounds like your network hasn't figured out how to route calls properly on their network when data is active, and they dump it straight to voicemail when there is a data connection active.
not the phone's fault, the phone won't even know that the call has been missed, the network simply does not route the call through and sends it to voicemail instead.
i had this on O2 a while ago. went to t-mobile (who knew how to set up their network properly for data) and never had this issue since when i am on 3G coverage. if i'm on 2G signal and have active data then yes, i miss calls. but that's how 2G networks operate.
it's truly shocking how many networks out there have absolutely no idea how to set up their networks properly for data!
Well I wish it would be that, my signal goes from -63 dbm 25 asu(80% of the time) to -81 dbm 16 asu.
Just after my post, I called one of my friend working in carrier terminal validation.
What he told me was, 2 options:
- Same bug was on the htc cruise, bug got corrected after a fw update.
- Some of my carrier radio are buggy and 3g goes over gsm.(SFR/VOdaphone France)
I bet for the first option since I had the problem in various places since I didn't want to ask support for nothing and get busted for a " feeling and not facts" (did the test in 3 differend location 80 tests in total(I used to be a tester....).
I will update the topic if I get news about it

You shouldn't accept it - but most people don't have this issue!
It's unlikely to be a "bug" per se, because otherwise it would be endemic behaviour, so it's either:
1. Your physical device (get it changed!)
2. Your network.
In addition, just an FYI in case you've got the new Sprint Hero, but most CDMA networks (including Sprint) do not support simultaneous voice and data. I've no idea what happens in practice on Sprint, but I'd imagine if you were actively using data your voice calls would get diverted to voicemail unless Sprint automatically suspends data when a voice call is pending.

Dave
You're on SFR?
OUCH!!!!
Sounds like you have a nice strong signal, but is it 2G or 3G? (do you see a G, E 3G or H at the top of the screen?
if you see G or E, it's cos you're on 2G, If you get 3G or H, it's on 3G.
And yes, there were a few issues with the P3300 and the cruise, but they were mainly on Bouygues, not so much on SFR.
There's nothing known of on the hero, and as SFR sell the Magic, i would have thought they would have ironed out any issues already...
Hi,
I'm mostly in HSDPA or 3G.
I still have contacts with people at SFR (used to work there till recently) they might share a bit of info.
Idk if yours is CDMA or the GSM one but on mine (CDMA) under the mobile network settings, I have the option to switch the mode of operation to ether Hybrid, EVDO only, and 1X only. Now, I know how Sprint's network works, not sure if it's the same for any other networks but if I set it to Evdo only (3g) I'll miss all my calls because Sprint does voice over 1X. Hybrid mode does EVDO when you're using data and switches to 1X when you're doing voice/sms.

Regarding this and your suggestion that 2g and data will result in missed calls, Can you suggest how to avoid this happening? I live and work in the country and only have 2g, so have found quite often people have mentioned my phone not even ringing- straight to answer phone. This explains it.
Nice to know, but annoying if I can't solve it- I run a business and my phone is very important.

Hi, I'm on hybrid
that is what i hate about hero, it is really great except for the fact that it switches from 2g to 3g without notice. i want it to be permanently stuck in 3g for faster downloads and mms, but when it uses 2g, i cant send and receive mms and surfing the web is slow as heck! im still looking for an app that would permanently put the device in 3g just like with winmo it which you can use wcdma ONLY.
cheers!
If you use AnyCut, you can create a short cut by selecting:
New Shortcut->Activity->Phone info
This will create a shortcut on your homescreen which beings up a hidden "engineering" screen on which you'll find an drop down for "Set preferred network type" where you can select WCDMA only.
Regards,
Dave
alternatively, open the phone app
dial *#*#4636#*#* and select phone info
scroll down and set it to WCDMA only.
does the same thing but saves installing an app.

That is not specific to the Hero. The fact is, every carrier's 2G network has better coverage than their 3G network. When the phone cannot detect strong enough 3G signal, it jumps back to 2G network. The idea is that slow data transmission is better than no data transmission at all. Many smartphones have the option to lock the mobile network to 2G only. One advantage is that it gets better reception, and another advantage is longer battery life (the 3G chip eats battery much faster than 2G).
If you instead lock the phone to its 3G network. The first thing you will notice is that battery life is significantly shorter. And chance is that you may be getting very spotty reception, because you are not allowing to phone to switch to 2G when it gets no 3G signal. When there is no 3G signal, forcing the phone to "3G only" mode won't give you faster download, it gives you no download.

true true. i usually charge my phone everynight though. problem that i have with 2g is that i cant send and recieve mms and yeah data connection is slow. in our place 3g signal is ok. i also lock my topaz for wcdma only. but it is ok that it switches to 2g in low signal areas.
Thanks!

Hi
I've checked it with Hero running in PlusGSM in Poland.
Regardless if I select 2G/3G or even "WCDMA preffered/GSM Only/WCDMA only" setting the phone is not available for incoming voice calls during data transfer. Every time when I start internet connection (example: SSH session) I'm not available for incoming calls. At this site I do have both strong 2G and strong 3G networks.
I would like to mention that a few days ago I've swapped Samsung SGH-i600 (WinMo 6.0) for HTC Hero - so I'm using the same SIM card in the same network and the same place. SHG-I600 was able to perform both data transfer (on 2G) and voice (on 3G) on the same time. HTC Hero is not...
I wonder if this is 'feature by design' or a bug in software?
is there anyway or any application that is out there that will let you browse the web and talk om the phone at the same time?
If you have GSM then you can do that without any special app. If you have CDMA then you can't do that unless you're connected via wifi.
Yup wifi and phone works really well LOL...

Just came out? AFAIK 3G on AT&T's network thats one of the benefits. I believe all 3G smartphones that had web browsing had voice capabilities at the same time... that's part of what 3G on a GSM network creates.
You can talk and surf in AT&T 3G network for sure. I am not sure if it works on T-mobile though. I would think it should, as it looks like it depends on technology and not the network itself!

Yea you can do this only with 3G connection. Cuz you are using E to talk I would assume! And 3G for data...
this is only possible using a GSM network(at&t, t-mobile...etc) without using wifi.
3g makes no difference in this situation.Verizon & Sprint run on CDMA networks and is not possible to "talk & surf" at the same time

Well the commercial is a response commercial to Verizon's ads... so at least in this case they aren't full of crap. Verizon's 3G network is based on EV-DO Rev A. You get the speeds of a 3G GSM connection but you don't get the simul voice/data functionality.

AT&T does not support browse/talk on its Edge network. So if your phone steps down to an Edge connection you lose that ability. AFAIK Edge CAN support the functionality its just that AT&T doesn't support it.
I will check on verizon when I get a chance, but if you look in the Kaiser forum, I showed everyone there in a thread how to get this functionality b'c the carriers (US) usually strip it out to preserve bandwidth. It has to do with the RIL settings in your provisioning xml. beeen a few years, but it is there if you want to dig. Look in kaiser rom development. Also, it has to be cooked in. the provisioning registry changes will always revert back to OEM settings if not cooked in.
It is not a matter of carrier but a matter of technology. Edge and 3G are akin to narrowband and broadband for landlines. Just like you can't talk and surf the web and talk on the phone on dialup but can on DSL. It's simply a matter of bandwidth.
To explain this in a more simple matter, 3g is essentially a CDMA connection. Being that CDMA carriers use said transmission for voice, they cannot use data and voice simultaneously. However, with t-mobile and at&t, voice is transmitted over the GSM radio and a 2nd radio is present which carries the CDMA 3g technology. If said GSM device looses that 3g service and falls back to edge or gprs, the simultaneous voice and data becomes inoperable. The key part to this is that a 2nd radio transmission takes place to allow the simultaneous transmission of both services. I have often wondered, however, why other carriers like sprint and Verizon don't incorporate a 2nd radio in their devices to simultaneously connect two CDMA transmissions similar to how a TIVO/DVR box works with cable/satellite services to allow the viewing of one channel while recording another. This functionality would allow them to compete with the GSM carriers.
cdma gsm
I know that when I used to work for ATTWS (long time ago), they were freaking out about the new carriers rolling in with CDMA (some with hybrid AMPS and D-AMPS 850 mhz spectrum) because, in theory CDMA should wax TDMA's call load significantly. TDMA, at that time could only hold 3 calls per channel. So about (here comes a geeky number) every 6.67 ms the calls on the channel would switch functions. Only one could TX, one could RX, and the other was Idle.... this was all transparent to the caller of course.. CDMA rolls around with the theory that becasue it's data piggy backed on the channel, it would increase their call handling ability 10 fold. Unfortunately theory didn't work out to real work practicality b/c the new PCS CDMA carriers really had about the same call capacity as everyone else.
Now, I've always touted VZW speeds here in my market bc TMO didn't even have 3g here till like 6 months to a year ago.. .and AT&T's 3G was laugable here in Jacksonville...might as well have kept the E or G icons on the phone for as slow as things ran.... HSDPA and UMTS could put a cramp on VZWs claim to speed...as long as they can get it consistent nationwide... I'd be tempted to leave for the right data speeds.....but for now, I'm in love with my overpriced VZW plan because of the coverage, quality, and speed..... who knows what tomorrow will bring.
Sorry for the long post, but it takes a bit to explain it.. (even though most of you know it.)
Thanks,

Thats definitely the problem make sure proxy is off and your connections setting are going to the MEdiaNet server and that should fix it.
I have a new HD2. It drops my internet connection when i get a call and does not seem to reconnect...I'm in the US, any thoughts. I thought both voice and internet can co exist. Thanks in advance

This is only true with phones that use 3G. The phone and EDGE (data without 3G) use the same radio. 3G uses a different radio so both phone and data can be used at the same time.
Thanks....BUT THAT SUCKS ... I guess I will have to buy the G3 version or get the Service Manual to enable the G3 US like you could due with the original HD.
I have a problem with the answer and some thinking ...Voice is over GSM(G) and Data is over Edge(E) why would it be dropped? I think that is 2 different radio Freq...

How would you enable 3G in the US when the radio does not support the US 3g frequencies?
I'm getting this also, but in Singapore and we do have a 3g network. even have the 3g logo showing up on the singal.
I got an email while on a call without wifi. I'm in dallas. Anyone else getting data and voice now?
Has been possible since the beginning of time as long as you are on 3G
I concur. ↑
Sent from my Nexus One using XDA App
Really? I've never been able to do that until recently.
Usually when I'd start a call I'd lose the 3G icon and if I received email while in call it wouldn't show up until after I hung up.
Couldn't mess with data without wifi.
Used to do this on my cliq and G1 as well...
Odd.
Also been doing both (on TMob 3G) since February...
Any gsm phone can do that, but it is impossible for cdma
Your phone may have been set to WCDMA only up until now.
chalk that up as a win for GSM and a lose for CDMA

WCDMA is 3G, it has nothing to do with CDMA
In a weak 3G signal area, the phone usually does a handover and transfers the call to the GSM network when the 3G signal falls under some threshold, and GSM doesn't support simultaneous voice and data (icon disappears while on a call)
maybe you have better 3G coverage now and your nexus doesn't need to go the GSM route
I've noticed problems with using data and voice together too. What seems to happen is that it works ok at first, but the instant you lose 3G it never comes back until the call is over, no matter how good your signal. Very frustrating when trying to use your data while on a long call.
Both AT&T and T-Mobile (as can any GSM carrier worldwide) can do voice and data at the same time as long as your phone has a "3G" connection visible while on the phone call. This has always been possible.
What you may see happen is that if you wrap your hands around the bottom of the phone during a call, the signal may drop to "E" or Edge. You can't use data and voice at the same time if your phone is on Edge.
To alleviate this, use a wired or Bluetooth headset, or hold the phone with your fingers rather than your whole palm.

Have you ever seen my problem where once the signal drops to Edge it will never go back to 3G? It doesn't seem like normal behavior to me but it seems to always happen when I need my data during the call. I've been stuck on multi-hour calls where my phone refused to go back to 3G almost from the beginning, and then the second I hang up the phone goes right back to a 3G signal with full bars again. Very frustrating!

the ATT 3G network is not setup to do handoffs from gsm back to 3g. it currently will ONLY handoff from 3G to gsm during a call, and if you are still on your call, it will not switch back until you hang up. in the future this can be enabled both ways. tmobile apparently is setup the same way for now. so you're experience is normal until they reconfigure their network.
Actually it depends on the phone hardware. It IS possible to use GPRS and voice as well if the hardware supports it, its not only something available on 3G/UMTS/WCDMA. There is a pretty even split between class A and class B phones these days, you should look up the specs of the phone you're using.
Nearly all 3G devices allow you to use data and voice together since it isnt timeslot based and so voice and data is logically split and not time divided. This means you dont need specially designed hardware to do it, just the processing power to do it.
Class A
Can be connected to GPRS service and GSM service (voice, SMS), using both at the same time.
Class B
Can be connected to GPRS service and GSM service (voice, SMS), but using only one or the other at a given time. During GSM service (voice call or SMS), GPRS service is suspended, and then resumed automatically after the GSM service (voice call or SMS) has concluded.
Class C
Are connected to either GPRS service or GSM service (voice, SMS). Must be switched manually between one or the other service.
@kam187, thanks for that. I've been with T-Mobile since they were Voicestream, about 10 years now. And I thought I was making voice and data connections with my Nokia phone years ago, before their 3G rollout.
Here is the last phone I used before going the G1 route.

Yep E61 is on nokia's list of Class A devices:
