Hi,
Just started with a problem with the defy not ringin out first time and now incoming calls are just as bad with people going to voicemail after they hear nothing for a few seconds no ringing just straight to voicemail.
Then it will ring in and out a few times then play up. The rest of the phones ok
Its a unbranded model all i have done is root and it updated itself to firmware 2.1 update.
seemed to be working great till a day or two ago. Have wiped and rebooted but its just the same.
On Vodafone and the sim works fine in other phones without problem.
Cheers Dave
You may be in poor 2g/3g signal zone.
I have the same isue in france with SFR provider (French Vodafone) it is a known issue here.
the problem is the same with all brand phone I've tried in the same area
Just force 2g on your phone and in/out call works fine

I took delivery of my new SIM free Galaxy Nexus today. Everything appeared to be going well until I tried to make a couple of calls. The call would either connect for three seconds and then drop or drop immediately. After dropping the call the handset indicates that it has no connection to a network.It will also drop any incoming calls and then I lose the connection to Vodafone.
To reconnect to Vodafone I either have to turn airplane mode on then off again or reboot the phone.
When it has the VF connection in the connection status page I see this;
Network - Vodafone Uk
Signal Strength - -95 dBm 9 asu
Mobile Network Type - HSDPA:9
Mobile Network State -Connected
After attempting to make or receive a call;
Network - Unknown
Signal Strength - -113 dBM 0 asu
Mobile Network Type - Unknown:0
Mobile Network State - Disconnected
I called Vodafone and they are sending me a new SIM (I've had this one for many years now). The current old SIM works fine in my old Desire.
Anyone else have these issues or have any advice? Is this a handset issue, SIM or could it be a problem with the VF network?
Ah someone else with this issue! I thought it was just me. I find that the vodafone connection drops and won't reconnect - particularly when I'm driving along. Sometimes it's fine for hours and others it just never returns.
I'd be very be very interested to here if a new SIM fixes the issue, as I too have had this sim for a very long time.
I love the device, but if it doesn't function as a phone I'm seriously considering either changing networks or returning the phone (which I got from phones4u).
My old sim works fine in my nexus S (which my wife has taken over and probably won't give back!)
I am still waiting for the volume bug fix which appears to have a new GSM binary, that may help the issue (or not) - otherwise its a call to phones4u to get me moved networks!
I got the volume fix when I powered up the phone today but that hasn't sorted it. Im off to a mates house now to try his SIM otherwise I may have to send the phone back.
I've posted this up on the Vodafone forum too -> http://forum.vodafone.co.uk/t5/Goog...-Signal-3-seconds-into-call/m-p/943023#M12291
Just to update - tried with a mates Vodafone UK sim and it worked fine so its looking like my old school SIM needs to be updated...
Just been to a vodafone shop and got a new sim. Made three consecutive calls. A record. New sim seems to fix it!
Sent from my Galaxy Nexus using XDA App
I'm on T-Mobile in the US and seem to have this same problem. I had my G2 and G1 with this SIM and never had an issue, but brought it to the Galaxy Nexus and randomly I lose connection and it won't reconnect until I reboot.
Anyone else see this issue?
I had a similar issue with an O2 sim on an SGS2. Replacing the SIM worked for me, though it was only 2 years old. I suppose its inevitable SIMs will fail.
Unfortunately, I got a new SIM card last night and put it in. But it just happened again today. Anyone have any ideas?
Currently I'm using Android Revolution 1.3.1 and Kernel 3.0.1-ga052f63.
Hey,
So I bought an LG G4 from Vodafone UK and unlocked it so i could use my Three sim card.
Weird thing is I can use Mobile Data and send/receive SMS if I am on 4G. The person who is calling me can hear the calling tone as if they were calling someone but I don't actually receive the call.
When I switch to 2G/3G it simply does not connect to the network.
I have done a factory reset and it did not fix the problem.
Any ideas?
Thanks
tl;dr : can't send/receive calls but can use data and send/receive sms (through 4G only)

Maybe you need to register your IMEI on the network? That's what I had to for At&t.
How would you go about doing that? Apart from manually searching for networks (I can see other carriers like O2, vodafone, EE, but I can't see my carrier Three ; the person living in the flat with me is on Three as well and they have no problem, so it's not a coverage issue. I have bought the phone from vodafone, unlocked it and trying to use it with Three).
Do I have to call Three for this IMEI registration or..?
Thanks

Best bet will be calling your service prover and have them register it. I had to call At&t and have them register my IMEI since I couldn't use internet or make calls.
Just had a long chat over the phone with them and in the end he said the 'engineers' found a 'problem' on their end and it should be fixed in @5 days. He didn't want to mention what problem or how / why it happened. Oh well fingers crossed.
Thanks!
update : so after about 4 calls with customer service (across 3 weeks) and 2 trips to the 'Three' store i'm basically stuck and would need your help guys.
backstory : I've contacted them once at the start of January and they said they found the issue and they will fix it by 7th of January which didn't Happen. On 7th of January they said they are sorry and it will be fixed by 14th of January which didn't happen either. After that I received a message that the problem was fixed and if i had any other issues I should contact them, which I did because the problem was not solved. Yesterday I went to the shop again and the 'tech' guy told me that it should be working and he gave me a new sim card just to be sure, and if that didn't work he said call customer support and ask for contract cancellation. Today I got called by customer service and I have told them that it still doesn't work and I'm paying for something I can't use and I've been told to request contract cancellation which they didn't believe and said I have to pay the rest of the contract length in order to cancel, which is absurd. I went again to the shop and the new customer service person that was assigned to me said they don't have any tech people and she seemed she didn't believe when i said i talked to one the day before. She tested the sim on their phones and it worked and also she took my phone "in the back (strange cause she said they don't have any tech)" and said I had my phone set to 2G (which I didn't, it was set to 2G/3G) and that that was the problem. strangely, for that split moment i had one bar for 3g and the call went through. Straight after that phone stopped working (it was just that small area in which it worked). I told her that that's not the problem and she's like "welp you didn't make your contract at the store, you made it online so I can't help you , you have to call customer service". So I'm basically stuck with a contract which I can't use and I have no idea what to do.
problem : I cannot register to the Three network (only in small random areas, few of them) but I have no problems with other SIM cards from other Carriers (Orange, EE, Vodafone, O2). I have bought the phone from vodafone and unlocked it and last time customer service told me they can't give support to phones that were not bought from their store. So I'm stuck here with a phone contract which I can not use to make or receive calls, but I can use the mobile data and send receive texts. I am considering rooting it and puting a custom ROM , although I'm not sure if that would fix the problems (maybe issues with certain bandwiths?.
Any help or ideas much appreciated!
Same problem here
Hi all. Same problem here but different issue.
Origin : G4 buy used on November. IMEI fully working and not blacklisted (calling my french phone provider this morning, it tell me that's IMEI is ok and phone not stollen and it try to repair remotly my carrier but didn't work)
Problem : Fully working since i picked up a call and answer ... and then when the call is finish i tried to call someone 10 minutes after and totally loose signal(connection) (Orange/Sosh)
What i've maid before : Playing a lot @ a boring but adictive game. High temperature since 3 days because i play a lot but temperature decrease when i stop playing.
I've used a legal app to record a patern and make some actions without my intervention (RepetiTouch Free (root)) to make races in the game.
That's all ! No drop, no hit, nothing ! Just playing, having a call, hang off and then want to make an other call and nothing.
Since the last 6 hours : Signal ok - Data ok (can go on internet / GAPPS etc..) - CAN receive and send SMS (i've don't trie MMS) !!! but .... can't receive and can't send any call.
I was on Genesys 3.5 and i've update to 3.7 when i see the problem, believing that's it will fixe the issue but ... no ....
Formating and going to stock ROM but with root SU etc..... Can't receive and send call too ....
I'm going to back to stock with KDZ .... but i really believe that's it will not work .....
AND .... to finish and kill my joy .... i've unlock bootloader with LG tools since 2 month .....so my phone is no longer under warranty.
My SIM card work on others phones ... other sim cards didn't work in my phone ....
If anyone have this issue ... please tell us
Sorry bro cant help you here. Never heard of that problem before but my idea is that you should refund that phone back to Vodafone UK.
Hello, I have two sims one UK and one from another country, when someone calls me and I am already having conversation on UK sim, I keep being informed that someone else is trying to call me so everything is good, but when I am on call on another there is no notification and the other person just gets disconnected after 3-5 seconds. When I have both sims from my current country it all works perfectly. I have been in contact with my foreign service provider and I have call waiting being set up on the sim and it works fine when I am abroad, does anybody have similar issue? I have looked through forum but couldn't find any clues or workarounds in this matter. I am on CM13 at the moment.
So I have used my S20 Ultra since March this year.
I've noticed that the cellular network just "sleeps" and doesn't receive calls/SMSes after some time of phone idling/usage on WiFi.
I tried googling and found many other users reporting similar issues, noticing also that it seems majority if not all are Exynos variant users (not based in US).
Personally, this is definitely not a telco provider issue as I have had this issue on my old SIM (which was working fine on my old phone) and new SIM that I recently got after switching providers to see if the issue went away.
For me, sometimes the calls come in a few minutes late, and then the phone rings but when picking up, the call just gets stuck because the other party is no longer calling.
This is particularly noticeable as due to mostly staying home during COVID-19.
Toggling flight mode to "wake" the cellular network makes the phone be able to receive calls again.

Lucky me. Didn't have this problem on my s20+ exynos

I also have this issue (S20+ exynos, dual sim). I use wifi at home/work and I had several missed calls and delayed text messages during this time.
Now I turned on the text alerts about the missed calls. At least when my phone connects again to the network I get these notifications.
I am also having this issue. People call and it rings out at their end but not at my end. Is there any fix?
Try switching the active number to slot 2. I tried it for a couple of days and I think it was better. I have switched back to slot 1 to monitor as I just got the ATE6 update and wanna see if it changed anything.
I had this issue and figured out what was causing it. You need to disable VoLTE if you are not registered to use this service on your carrier's network.

My sim cards are already registered to use VoLTE, my carrier notified me a few months ago about it.
I tried to disable VoLTE on both sim cards. It was OK for 2 weeks until now.
I got a new missed call notification text message and after 5 minutes a message from the caller.
Now I enabled VoLTE again for one sim card. Let's see if there will be more missed calls with this setting.
Hello, I bought an S7A on eBay. I unlocked it with the GSM unlock code provided. Everything works fine, except ... I can't make or receive calls. When I make a call, no ringing tone, and it hangs up 20 seconds later. When someone calls me, the same, then they come across my answering machine.
I'm on the latest version of Oero available, no root or whatever. From what I saw (on GSMArena), the phone uses compatible frequencies in France.
I am at carrier Bouygues Teelcom.
You have any ideas ? Thank you !
PS: I translate from French, please be indulgent!
Same problem, this phone does not work in China
Since then I have understood the real problem: the phone cannot switch from the 4G network to the 2G network for calls on its own.
I don't know how I did it, but now I can make calls without any problem, but switching to 2G is very long (15 s).
I specify that it is impossible to use VoLTE to circumvent this problem.
For receiving calls, the phone does not switch to 2G and the incoming call still fails.
But I can force the 2G network (With the Samsung Band Selection app). And there, incoming calls work, but we only have 2G to surf.
When connected to WIFI, the phone automatically forces the mobile network to 2G, so incoming calls work without the application mentioned before.
