Good day all, a friend of mines recently bought an unlocked galaxy s2 online..out of the box the imei number was resetted to the manufacturer's default 0049*** number. I used the samsung srs tool and programmed the correct imei to the phone and it started getting network signal BUT places where I am getting full bars with the same network provider and same galaxy s2, his phone is getting real poor signal or even none. The only way he phone is receiving full bars is areas closest to the cell tower..the only difference in the two phones are the roms..I have the leaked jellybean whereas he has an unbranded uk rom. What can be the cause of this?

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.
Get it here:

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.
Hi everyone
I'm new here and I have Galaxy S2 on Virgin UK network. I would like to ask S2 owners or anyone who can help me about advice. I spent hours in many forums and I still can't truly get what is wrong with my phone.
The problem occurs when my phone is working in automode (gsm/wcdma). When I get to place without proper 3G network coverage my galaxy s2 goes in to 2G and never comes back from it to 3G (in automode). When I want to come back to 3G I have to reboot my phone or toggle it manually to WCDMA only for a second and switch it back to automode. Whenever I do it I'll have 3G (or H) to the next time when I'll go to the place without 3G coverage.
Is there anyone who owning galaxy s2 on Virgin UK with working 2G - 3G switching in automode (gsm/wcdma). Anyone even in other UK networks or it's just normal behavior for galaxy s2? I know at least 2 people who have the same problem with S2 and Virgin.
I've tried many different roms and a lot of modems too (even orange UK, 3UK, T-mobile UK stock modems), Juice Defender beta, other software switchers and wigets.
Help, please
Not on virgin, but a UK user on 02. Never experienced the issues you are describing, so it seems network specific.
Thanks mate. I need all your opinions before I'll complain to the Virgin.
Possible its the masts you are picking up from .
SGS2 and 1 bothy worked fine on Virgin for me >> have you entered the correct settings from the web site .
CSC for Virgin i always used the CPW carphone warehouse one as some UK csc do not have Virgin settings .Virgin of course runs on the TMobile network .

That will of course have invalidated your warranty from Virgin .You need to restore if sending the phone back .

Of course. I came back to stock firmware 2.3.4 last night anyway.
Thanks I'm going to check CPW carphone warehouse. Settings are from Virgin website and I'm picking up signal in BT4 1QF area now.
EDIT:
Well
I flashed GT-I9100_CPW_I9100XWKF3_I9100XXKE7_I9100CPWKD1 - CPW carphone warehouse with factory restet before of course.
Phone started in 3G obediently. I switched from automode to gsm (what occurs when I'm in place without 3G) and I switch it back to automode again to check whether in goes in automode from 2G to 3G or not. It was last time when I saw 3G icon on the screen. No luck. Still doesn't work. Absolutly the same.
I've heard similar stories on other threads, It may be coincidence, but Virgin runs on the T-Mobile network, and they have just recently started sharing their 3G network with Orange.
There may be some hiccups in the switch over, that's affecting Virgin.
I could be totally wrong, but the dates coincide with the similar Data issues that I have seen discusssed on other threads.
I would call Customer service personally.
Regards and good luck.
I just finished my conversation with customer service. They said that It can happen in places where 3G signal is weak and 2G strong. If there is strong 3G signal switching should work. It should but it doesn't. Thats what I known now. But I'm afraid I knew it before already . They said I can try to replace sim card or mobile.

I've noticed this a bit with my galaxy S2 and its quite annoying, i used to get the T-Mobile network all the time which provided me with 3G quite often but for some reason the switch has left my phone connected to the orange mast with no 3G. I might ring up as well.

I upgraded another device with Orange last week, and they provided a new SIM card. I'm wondering if that's due to the switch.
Good luck.
Regards
I'll try to replace sim next week
Not seen this problem (for me) on my SGS2
SGS2-XXKL1-Hyperoid 5.2.21/Siyah-2.6.7 - Virgin UK.
Although my Virgin Blackberry has the very same problem? time for a customer service call...
Well I sorted out my problem pernamently and I now what is going on. This is network problem. Go to your network settings and change your network from Virgin to virgin I spent 1,5 hour speaking to Virgin support and they couldn't help me. The didn't know. They told me that virgin with small v it's orange in fact but we can use this network that's why it is also named virgin.
Regards
Check your connectivity with calls. My wife is with Virgin but can't get signal at work or home. Their signal on data is only the second usage of T-mobile which is not the best.

Looks like this new EE network is now T-Mobile and Orange. What are Virgin using to do their data?
Hello comunity. Im Elian from Argentina. Im following this forum for quite some time but i never posted. So this is my first post.
I bought a chinese replica from a popular dealer from Aliexpress 1:1 of the Samsung Galaxy S4 - (MTK6589) with air gesture, smart stay, and flipcover support.
Based on what i've read seems to be a HDC Galaxy S4 Legend, but im not sure.
Everything works great except for two mayor issues:
Phone Signal does not work good. I have to be outdoors, out of the house to get a usable signal
Wifi Signal is poor. I have to be standing 10 feet from the internet router to get a decent conection
My local phone company (Personal Argentina) works on band 850 y 1900 Mhz
Does this two issues can be solved by changing the original rom to a custom one like hdc S4 legend Fluffy Galaxy S4 CWM FLASH NOTE3 PORT from Fluffy ??
Anyone of you had a similar problem ? Thanks
No outgoing or incoming calls with different network and ROM tried without success.

Hi guys,
I bought a Samsung Galaxy S6 Edge SM-G925F sim free
Build number LMY47X.G925FXXU2COH2
Baseband version G925FXXU2COH2
5.1.1 Lollipop
Previously my Oneplus One on Three network (UK) I would have full Lte signal but on my S6 Edge I only got 2 bars. Changing to WCDMA/GSM I get great signal and in speed test is actually faster than LTE.
I'm not rooted and I'm wondering if this is a software problem or hardware, and if flashing a different rom would help?
I don't mind tripping only if it will fix the problem.
Thank in advance.
I got s6 edge+ last week. Bad reception. Changed the phone, in the AT&T store. The second phone is even worse.
Initially the store employee told me that there are no new phones in Stock in their store. But he said he found one.
Since the second phone is even worse, is it be possible that, the store gave me a defective phone returned by a prior customer?
He opened the box in front of me. But I am not sure, it's brand new.
But anyway my replaced s6 edge + is even worse.
Folks, any suggestions?
I'll wait for the next update (marshmallow) and see if iit makes any difference.
Hi guys,
I had purchased a Samsung galaxy s3 in India from ebay(big mistake) 2 years back. The mentioned model number of the mobile was GT-i9300 however I was not convinced that it was i9300 because it has got 2gb RAM. In About phone-->model it shows GT-19300 and even when the phone starts it shows GT-i9300. However in download mode (power + vol. down) it is mentioned to be model number SGH-T999. This is the most confusing this. (in binary counts it shows 1 too ). But in rootchecker it shows unrooted device. So I decided not to root the phone has it may brick it. Its on android 4.1.1 and when i try to update via OTA it shows "Your device has been modified. Cannot update"
I didn't much inquire that time since the phone was functioning very well and had no problem. But now when i insert 4g sim (Airtel 4g) the sim-card remains undetected. No problem with 2g/3g sims.
It would be really helpful if you all can assist me with the 4g sim issue.
Sounds like you bought a blacklisted phone with a cloned imei put into it so it could be activated... Google that model number that comes up and that'll show what phone that's really from
I just looked up sgh-t999....that's T-Mobile s3 someone flashed it and sold it to you man

Thanks for replying. The phone works absolutely flawless except about the new 4g sim. I was using old sim (3g) for past 2 years but recently bought a new 4g sim and phone does not read it It shows "Insert a sim-card" message only. Tried with other 4g sims too and doesn't work but other sim-cards are accepted. Anyway by which i can make the 4g sim readable by phone. I particularly don't want LTE to work .....just the sim should be readable by phone
4g cards are different. I9300 is not 4g.
I9305 is lte variant and accepts 4g cards afaik.

I know that 4g(LTE) will not work on the phone but the phone should still read the sim and at-least give 3g speed. I inquired this with service provider too taht my phone is not accepting card and even they wondered and said it should work and there is some defect with phone. I have got another s3 (gt19300) and that can read the card. I even tested on HTC ONE X (not a 4g phone) and still the card is read by the phone and gives 3g network.
4g cards can be accepted by 3g phones only that it wont give 4g speed otherwise it should work
