Hi everybody.
Got my brand new GS2 and I have this problem.
When I make a phone calls, after few second, the phone switch between 3G and 2G (and this is normal, all my phones do this).
What is not normal is that this switch between 3g and 2g causes a 1/1.5 second voice drop, so that I often miss the "hello" or the first words of the other person talking to me, and I always have to ask people to repeat what they've said. Very, very annoying if you receive 10-15 calls every day.
I've tested a Nokia N86, Nokia C3-01, a SonyEricsson, and all of them do the 3G/2G switch immediately after a make a call, but it's instantaneous and I don't miss a single word.
Tested other phones/sim card/areas and the GS2 seems to be the only phone that switch 3G to 2G so slow.
I've 2.3.4 (last available in my country) and Vodafone, and no other issue apart this though.
Any help please?
nobody?
From your network settings, set it to GSM only and see if it still happens. If it does it may not be related to the switch.

I've tried it. If I force the phone to 2G of 3G this doesn't happen. But I have to keep the phone in dual mode, is necessary to me.
The issue is certainly related to the 2G/3G switch, I can see it watching the signal bars in the upper part of the display.
i also had a problem with internet and calls.
Whenever i made a call, my h+/3g changed to g (i dont even know what that is, edge?)
after the phonecall it stayed on g unstill i restarted or went into airplane mode which really sucked!!!
But this is how i fixed it, and it might also fix your problem: download greenpower and let greenpower disable the internet while you make a phonecall!! Now i have no problems anymore
If you have rooted, flashing new rom could fix your problem

First of all i must apologize for not posting on development but im not allowed since this is a new account on xda...I live in London but im in mallorca spain for the summer looking for a job so having a phone is very important. As soon as i got my sgs2 i rooted it .. i was having some issues (random reboots) which led me to think it was either something wrong with the unstable kernel i was using or more likely a bye bye RAM. I decided to reset the phone and installed the LIGHTENING ROM... I Just love it!!! but... now im having trouble with it ... (BIG TIME) I had not realized something was wrong because everything seemed fine until i asked my gf to call me today... she couldnt... then i tried several times myself without success. I rebooted and to my surprise i started receiving a lot of work calls!!! (Which is great) but then i tried calling myself and it didnt work again. Im going back to stock firmware for now since the device is a phone after all. Dont know just yet if this will fix it but ill keep you guys posted... anyone having similar issues??
It might be a small bug in your firmware, try reflashing Stock and then see.. If still the same problem, try stock firmware from another source and reflash.. if still the same problem.. then its a issue.. Post your findings.. please
I have no issue like that.. just trying to help

check if your internet connection is set to wcdma/gsm auto mode...i am having similar problem when it is set to wcdma/gsm auto..it keeps loosing connection and radio switches off...making my phone unreachable most of the time.setting it to gsm only is the only way to cure this at the moment for me.

hi iznee;
I am from malaysia too.
currently I am using stock KE2 ROM. just rooted the phone for some xtra things that I want to do with it.
my phone is set to wcdma/gsm auto connection and never have outgoing/incoming call problem. Data also works as expected and by the way I am subcribed to Celcom unlimited Data plan.
by switching to GSM only, you are limiting the speed ability of the data to GPRS/EDGE only. please noted that you cannot have voice and data simultaneously while in GSM only mode. your Data session will be suspended if you make an outgoing call or if you receive an incoming call.
however, if you set it to WCDMA only, you can have both Data and voice simulataneously and that explain for 3G video call. but, not all areas are covered by 3G thus, if you entering an area without 3G, your phone is useless because there will be no signal.
if you set it to WCDMA/GSM auto, the phone will switch to GSM when there are no 3G signal available and that will ensure smooth phoneoperation in making/receiving call.
After a week of usage, I can confirm to you that I never have outgoing/incoMing call.problem and no data.problem.

Well so far my findings are null. i flashed kd2 stock with odin with the re-partition parameter on. Nothing happened. Was thinking re-partition would actually get rid of all the apps in case something there was giving problems... the phone was working fine when i was in england with kd1 stock... (How do i get rid of everything and start from scratch?? and what does the efs option do?? im tempted to use it xD) ... One other thing is i read somewhere that kd2 was giving trouble on orange uk (im ukthree but have tried with vodafone spain simcard) any ideas???
Efs is your IMEI code etc.
Backup as per post dev section .

iznee,
I have done a test regarding call in/out and also data connection. below are the test;
I am driving from KL to JB and crossing 5 states (KL, Selangor, N.Sembilan, Melaka and Johor). Along the 400km routes, I have taken the NorthSouth Highway, federal trunk road and also state road. My phone will change from H/3G to E/G when the signal is not available and I've no call drop whatsoever. I made calls while 3G/H signal is strong and also received calls. I did use the google maps.so that the data connection will be.continuous. In 3G/H mode, I can make/receive calls while the maps constantly refreshing based on my driving location.
when I enter the are without 3G, the phone automatically switched to GSM mode. albeit a bit slow.in data.connection, the maps still refresh without fail. when I make an outgoing call, the maps will stop refreshing as this is the behavior of GSM that voice call will take.charge and data will be suspended until I hangup the call then the data automatically resume its connection and the map refresh automatically showing my driving location. Then I use my other phone and call my SGS2 and as expected, the voice call going in and data suspended temporarily.
after hangup, data resume again and the map refresh automatically.
and when 3G signal is available, the phone automatically switch to 3G/H mode again and vice versa along the route.
all in all, I can say that my SGS2 works wonderfully and meets my expectation that phone function is priority. sattelite locks will take no.more than 10s and sometimes just under 2s. Superb performance by the phone.
Camera wise, no complain as I am.not a proffesional photographer. and I am more than happy for the camera performance.
Battery wise, no complain as I have unlimited data so i have all.my Facebook, twitter, push mail, livescore, news, weather etc ON 24hours. anyway, I have vehicle charger with me so the phone will be charged as long as I am driving.
this is from the about of the phone;
Android version: 2.3.3
Baseband: I9100XXKDJ
Kernel: 2.6.35.7-I9100XXWKE2 - CL187606 [email protected] #2
Build number: GINGERBREAD.XWKE2

Sorted!! I made a hard reset... Which led to a bootloop. Fixed turning phone off volume up+home+power . Clear everything and reboot... Voila now works like a charm hope this helps otgers in my situation
Does any one face the following problem, it happens almost Daily at least once:
when i receive a phone call, the SLIDE to ANSWER or Pressing the home button ( i set home button to answer calls) does not Answer the call... the CALL is left in the background and i can not either Talk or even End the call!!!
i have to reboot to make a call afterwards!
i flashed KE2, 7 & and now 8 with no difference. i even Flashed the RADIO from the very ORIGINAL stock and no LUCK either...
I noticed that sometimes when this happens flight mode automatically becomes on! Really strange...

seems only you and me dear in this issue... so lets share and try to find what is causing this problem..
do you use any profiles app. or task management app, etc.?
Im on Samsung Omnia 7 and my phone have issues with incoming calls. I get silence when i answer. And my friend just bought Samsung Galaxy SII and he have the same problem. It only happens when you use a specefic carrier and it only happens when your in a weak signal area.
Also notecing a lot of internet connection, bandwith changing. Its all over the place all the time. Edge, 3g, 3g+ .. i belive on Android it says HSPA and HSPA +. But it seems its the sma problems with all Samsung devices thats new.
Hello everyone, i'm asking this because it's the third time i had this issue. I often keep my Data Network Mode deactivated and turn it on only when i need because of my 3g plan (quota, taxes, and also because it's likely to find a WiFi network in the places i usually go).
The problem is, sometimes i turn on 3g (by Phone options menu) and... nothing happens... i need to reboot to make it work again.
The 3G network in my country is quite unstable, but i'm pretty sure that isn't a signal problem because one of the times i was turning on/off the 3G to make it work and i gave up and forgot to turn it off, the next day when i tried again i found it was On but not connected. After a reboot, working again.
Anyone having this issue who found a fix? Could be a problem with the kernel or app?
Edit: I Forgot: CF-ROOT Kernel, KF3

mate i am afraid you have answer already - "The 3G network in my country is quite unstable"
that can clearly produce the bug. Just in the case check your APN settings if they are correct. Settings- wireless and network-mobile networks- access Poin Names - compare the stats there with your network provider and make deep research.
just example i am on vodafone - i found that i was running vodafone live profile in APN and i was loosing conexion and i had troubles loading some pages - after research i found that there is another setup for vodafone as well - different then the live but for vodafone as well. i am using it since then and i am experiencing now the lighting speed of 3g. Just give it a try.
Searching on the internet i found that the configuration of my APN is equal to the recommended.
Backup data and factory reset phone should clear any software problems .
You could try flashing KH3 modem .

Same issue here for both rooted and un-rooted GS2
Retracted - will have to do more testing
So I bought a new Galaxy SII and pretty much rooted it as soon as it arrived, I use CyanogenMod nightlies and update daily to the most recent version. It worked fine for a month but at some point when people called me, the phone would automatically hang up and i'd hear stange sounds, the phone is prepaid but at some way, if i'd enable connectivity I would still be able to use WhatsApp everywhere (it also said thing like H, H+ and 3G)when I had a signal, even without a data plan.
Then after a while it just said KPN (my provider) in the lockscreen but the signal indicator would be black all the time (no sim-card detected), now it's even weirder, you know when you turn on Wi-Fi and it connects, the Wi-Fi signal bars will be gray for a while and then blue and when it's blue you can use the internet. Well, as soon as i'd turn on Wi-Fi and connect to one of my routers, both the Wi-Fi AND sim-card signal would get 5 bars, and the sim-card signal bar would also get gray and then blue, so I thought yay I can call again, nope, it says full bars, it says KPN but as soon as I call someone the screen goes black for a while and then the phone app crashes ...
Can someone help me? Is this a software problem or something intern? Is this repairable? Please let me know
The 1st screenshot is with Wi-Fi, the 2nd one without Wi-Fi for a few seconds and the 3rd one is without Wi-F- after half a minute.
I hope someone has also experienced this and knows how to fix it ...
Someone?? I will by a new phone if nobody knows how to fix it, I can't even call or text right now..

I've purchased Redmi Note 3 Pro a few days ago. I'm satisfied with overall of the phone but there is one problem I'm facing.
After I quit airplane mode(every night I turns on airplane mode before sleep then turns it off in the morning), my phone won't detect the network most of the time, sometimes it detects the network but it took way too long to happen but still, it acts like there's no network. I couldn't call, sms, receive call, receive sms and use mobile data. Everytime I have to restart my phone to detect the network.
Is there any ways to fix this problem ? It irritates me a lot as I have to restart my phone everyday.
update your phone, this issue has been solved about a month ago
Yeah the new builds are much beter
Hi guys,
I also have network problems on my Note 3 Pro - but without airplane mode. My phone just randomly looses internet connectivity, sometimes completely, sometimes it drops to Edge, most of the times with a warning about roaming and data connectivity. And yet sometimes I completely loose mobile signal but a on/off airplane mode fixes it.
It's pretty irritating, I didn't have these sort of problems with my prev. phone, and I haven't visited any new places or with bad reception.
I'm running the 7.1.8.0 global stable rom.
PS: My locale is missing, and I chose Argentina on random, then disabled auto-time. Could this mess things up ?
Any input would be appreciated.

I am facing a terrible network problem with my phone too. I have used China and Global ROMs and I cannot fix the problem. I am currently using Global 7.1.8.0
My phone does not respond to incoming calls when in sleep mode. Incoming calls go directly to voicemail. It seems that it is connected to the network while in sleep mode. However, it does not respond to the incoming call.
If the phone is awake with the screen on, it shows an incoming call.
I have tested other SIM cards, switching from 3G to 2G, reseting the phone, clearing cache, disabling "do not disturb".... The problem just does not go away. It's a shame that a phone with this much potential has a basic problem like this.

Just tested, mine rings when sleeping. But define sleeping... ? When display is off for a some time ?
I am also suspecting something with the sleep mode, it usually 'switches' to Edge or no connection while in my pocket. I am also suspecting problems with the sim card, have you tried with a new one, or card in another phone ?
Otherwise I really like the phone It brought my trust back in Android.
edit: Update > Download Update and it started downloading, then restarted, installed something, but I'm still on 7.1.8.0 ...
Auto download is ON.

I define the "sleeping mode' as phone with screen off for some time. I tried different SIM cards and from different network companies (3 and Vodafone). Same problem. My network signal is extremely unstable. I like the phone a lot too. However, network signal is something so basic on a phone that it is a shame it does not work properly.
I am also facing similar issues but xiaomi people are not recognizing the issue. They are telling that it's an isolated issue. Please post here, so that they fix this problem.
http://en.miui.com/thread-255747-1-1.html
I got a new sim card, and upgraded my plan, now I have good reception, almost always LTE, sometimes drops to H+. How I miss calls when my phone's display is turned off/sleeping. I'm getting pretty pissed of with Xiaomi about this ****
So annoying
Hope we get the 7.2.2 update soon and it fixes this problem
What good is a phone if it has network issues

Forget my previous posts on this issue. Follow these steps as they worked perfectly for me and I had to repeat them this evening since I did a reboot.
1. Keep sim registration on automatic on both sims.
2. Power off phone.
3. Remove sim 1 and keep sim 2 (my sim 2 is 3 Mobile UK roaming. That may make a difference).
4. Power on phone. My roaming sim 2 registers immediately.
5. Power off phone.
6. Insert sim 1 (primary or local sim).
7. Power on and you should have both sims working perfectly.
8. Go to sim settings and change your preferred calls and data back to sim 1 if you need to.
These steps have worked for me twice so far. Hope it helps.
P. S. I must add that I have zero, zilch, nada issues with my Zenfone 2 running the same setup (local sim and uk T-Mobile). Love the Xiaomi so far but detest the lack of native alphabetical for the apps. Considered Nova but the free version doesn't give message counters. Any suggestions?
There is a temporary trick posted at http://en.miui.com/forum.php?mod=viewthread&tid=251620&page=1#pid4736228
I was having network problems and it seems to be much better (perhaps solved) with this trick.
I wish to know what this com.qualcomm.qti.supersaver does!

I am glad it helped you. Make sure you type the code *#*#995995#*#* twice after stopping the apk. I actually disabled this apk without any secondary problem.
I am running Global ROM 7.1.8.0. Still waiting for 7.2.2. Let's hope this problem will be fixed in the next update.
Hi,
I'm also facing network issues with 7.1.8.0 : when exiting airplane mode or switching from Wi-Fi to gsm network, I lose data connection. The only way to get data back is to reboot the phone.
Sadly, the trick from miui forum didn't work for me for this particular problem.
Il hope this problem will be fixed in 7.2.2.0 update.
@ mura20 : thanks for the trick nevertheless...
OTA 7.2.3.0 is here!
OTA 7.2.3.0 solved my problem !
Great
I also got the new ota. But how to flash? Twrp returns error 7 when I try to flash
