Hi all, I am having a problem with signal strenght on my i9100. When the phone is on a table the signal is about 3 lines, at 70% of strenght but when i hold it in my hand it looses reception and it says only emergency calls, I've tried everything, changing the software, official/custom, tried different SIM card, trying 3G/GSM, nothing, I've even changed the antenna, same problem again, how can it be solved? Can it be a problem in motherboard or?
The problem is just like on example video.
Please help!

My phone is locked on to VIP Croatia network, I've unlocked my phone using paid GalaxSim unlock on T-Mobile Croatia, the signal was weak just like on VIP network, then i flashed I9100XWLSD_I9100CROLSB_CRO which is for T-Mobile Croatia and signal was also weak, then i flashed I9100XWLSD_I9100VIPLSC_VIP for VIP network and signal is also weak, I tried both, VIP and T-Mobile SIM cards, on both of them is signal weak.
Could you please recommend me a modem, because I'm new to S2 and don't know which modem will be good.
Tnx in advance!

Ok, tnx, I will try to flash this modem, and will call back the results.
Tnx in advance!
Or just search for veyka modem list as theres loads there.
None of that helped, I'll try to change the RT module, the one with micro usb, maybe is something on it making problem, i have a spare from other i9100 on wich is microusb not working but antena works so I'll try with that and report.

Hi there,
Since a few days, I've got a serious problem with my SGS2, it randomly loss any networks, saying that the flight mode is on. I tried to flash with another firmware ( stock KE7) it change nothing.
Any idea?
This is a firmware issue with the modem. Mine did the same thing. KE7 modem is horrible. I flashed to KF2 modem and I don't have this problem anymore.

i believe this is related to the network itself. for my 2 other phones before, whenever i am AUTO network Mode, many callers used to call me reporting 'My mobile was off'... also with S2 the same issue.
i switched to GSM mode only, LOSING my NETWORK Data SPEED, for this ..
i hope future firmware can solve this with as suggested above, Good RADIOS....
The problem is that i've already tested with another provider's simcard and i've got the same issue. I tried with some firmware (stock KE2, KE7, KF1, Litening 1.4) but it change nothing. I'm from france with 'Virgin" provider if this can help.

up to now, going to GSM Mode solves this issue but i loose "fast speed network"
I tried GSM Mode only but the issue is still the same.

i am currently on the same build... in fact i tried all previous builds and even KF1 & KF4 but all were the same
I have this problem with my WiFi network.
The title on this thread doesnt say which kind of network you are talking about.
Data network and phone, wifi network works perfectly.

I'm on Orange UK and that happens to me quite often. It's something to do with the network and how it handles the switch from gsm to udma(I think, anyway). Sometimes the network doesn't fully recognize you've switched from one type to the other and reports your phone to be offline. It doesn't usually last long but if someone tries to call me during that time then I'll get a text message when the network catches up to tell me I've missed a call.

What is even worse is sometimes in the middle of a conversation it goes to flight mode!!!!!!!!!!!!!!!!

I don't think the problem can be fixed on the user end. I had the same issues with a Nokia N80 and N97 mini before I switched to the SGS2. It's apparently a common problem that all networks sometimes have and the only way it'll ever really be fixed is if the networks improve how they handle the switch.
I think it also depends on where you live. If you get a constantly good 3G/H signal then in theory the phone should hardly ever need to switch to GSM mode, but if you live in an area where the signal is not so strong then it might switch more often which will cause the problem to be more severe.
You could of course try setting the phone to WCDMA only which will give you good speeds, but then if you drop out of 3G range you'll lose the ability to make & receive calls anyway. It unfortunately seems like a lose/lose situation.
As for the flight mode issue, I really have no clue what is causing that. Have you tried hard resetting and/or flashing new firmware?

Change your phone..
I had the same problem on my first SGS2..everytime when gsm/wcdma auto is selected..phone randomly looses internet connection and radio switches off. In gsm only mode..everything is fine. Got my second SGS2 and phone is perfect..no loss of data connection even in the worst coverage area..
You can read "serious issue on 3g" thread in the general forum and see if you are suffering same symptoms

You need to ask the network if they are having problems .
Have you checked /remade your network settings ??
Could be a rom problem a modem problem a sim card problem or even a CSC problem with wrong settings .
Check settings clean sim card that does not help put your phone back to a warranty state flash stock rom and clear rom counter . Test if faulty take to a service centre .

Im on 3 also i have had a few times the same problem mate, lets say maybe 4 or 5 times, it usually happens if i lose my internet connection it still shows me having signal but cant make a call or sms. i got no answer from 3 either
Check the status screen. I get this and when it happens where it should say T-Mobile it says Emergency Calls Only. I figured my SIM card was at fault so wedged some paper behind it to hold it in place and the problem has almost completely stopped.

Rub the terminals on the sim card with a rubber to remove any static build up

Are you guys running an I-9100T from 3? All modems from any rom you install won't work with the T. You'll need your stock KF4 modem.

I had a similar problem. Read more about it here:
http://forum.xda-developers.com/showthread.php?t=1225849
tried going back to kf4 still no luck its only in certain places in me house where it does it everywhere else i have 1 or 2 or none at all bars of signal
3 customer service rang me up told them i wanted cancel the contract bcus of it. they knocked the contract price down from £30 to £25.75 for the text 500 plan with them. bit annoyed that i can only get signal in certain places of me house but cant argue on the price as well as gettin the phone for free
because 3 dont have a 2g network in the UK so if you dont have 3g coverage it will show a network signal but you cant make calls or sms
I'm having the same problem but with o2. I lose signal regularly at home as I live on the perimeter, but when I get signal bars back againwhen i go into town, it tells me that the network is unavailable. I have to switch off and on again to re register and then it works fine again until the next time the signal is dropped... It's annoying in the morning because i can wake up and see full signal on the phone all morning, but people are trying to contact me and not getting through because in reality, the network is not connected! I'm sure o2 have a 2g network, so I would presume it's a phone issue...
Hi all,
I live in France using SFR network and I get the same issue here using KI3 but I had the same problem with KH3.
the behavior on the phone is network seems to be good everytime/everywhere but sometimes people who try to reach me go directly to my voicemail and I receive sms with some delays.
When network works again, I mean I don't see it but I know it because I receive a couple of sms at the same time and a call from my voicemail
it means that my phone seems to be connected to the gsm network but is not, It loose the gsm network...
If you can give me your experience.
thx
I've got the same issue. (tacticman), I'm also on SFR network, i had this since KH3, never before. Now i'm on KI3, it's still here.
I always use CF-Root kernel, i tried to wipe, restore old backups, it does not change anything. I also tried GS II repair tools, nothing too...
The only thing I found to solve (temporarly) the problem, switch to offline mode (mode Hors ligne in FR) and then disable it.
But the problem occurs very often, it's very disturbing.
My IMEI number is still here.
My Galaxy S 3 got a problem. When I choose the network only wcdma, no signal appear; if I choose only GSM, the signal is good; WCDMA/GSM, some seconds no signal and some seconds has. I have updated some firmware, but all is the same. I do not know what happens, and can some body help me?
Looks like your provider has rubbish 3G coverage
Try different simcard on network with good 3G/2G and then see what happens

No, other's telepohone has a good 3G signal except for mine.
Hmmmm... Try different modem, if still nothing than your 3G antenna can be faulty or disconnected...

yes only useful to some users, not me. I failed again. So what's wrong with my galaxy s3, it's a hardware porbelm or software problem?
Speak to your network first and check its coverage maps .

Hi. My Galaxy S3 i9300 drops network connection from time to time for no reason. I have a full coverage in the city, all the signal bars are full, however it drops the signal sometimes and reconnects again. That's very annoying while talking on the phone. What I tried so far:
Clear cache
Hard reset
Changed to another custom stock rom
Installed another kernel and modem driver
All these makes me think that it's a hardware issue. Anyone who knows what it might be and how can I fix it? I have a hot air gun and I am able to replace parts if one knows which part might be faulty on the motherboard. Thanks!
*#*#4636#*#* and change to gsm only (mobile network will not work, changes work untill reboot). Use that if johnny_GSR post dont work for you.
Hello, i lost my antenna signal and i can´t get it back. I´m using CM13 snapshot 20.08.

Hi, i have a gt-i9100 and i noticed it has weak 2g/3g signal ,even compared to other old phones. In the same spot and with the same sim card ,only the i9100 is not able to receive phone calls and i also tried different usb flat port and different antenna cables and i tried also the only cmda 3g mode.
Are all the i9100 like this or mine is faulty ? Could i solve this if i buy another motherboard,even a chinese one? Thanks
check the modem you have and perhaps change it
https://sourceforge.net/projects/hcteam/files/GT_I9100/Modems/
I use Modem-XXMS4.zip for Europe. here are some list of codes of modem

Thank you , i tried many different modems and many stock rom versions with ms2 , ms3 ,ms4 etc ,but in some places where the signal is weaker the s2 is always the only phone which is not able to receive calls,even if phone status info shows 10 asu and the icon has 2 bars. When the signal is a little stronger it works .
Did you never notice this problem compared to other phones?
I could buy another motherboard but i don't want to end up with the same problem if all the i9100 has this level of reception.....
If you have changed the USB board in the phone, then that is probably your problem. It likely has NOTHING to do with the modem.
There are several variants of the USB board and you *HAVE* to replace the board with the same variant you removed, otherwise loss of signal can occur...
I wrote a guide on this very subject.
It will help.
