Greetings
I have bought a sim free galaxy s2 5 days back . I am in japan.
From day one I have been facing strange problem. If my 3g disconnects for some
Reason such as going into elevator or traveling in underground,
It doesn't come back. I have to reset my use data package network settings or
Turn on the flight mode and turn it of f again to get connection back.
My apn settings are as per my carrier has suggested.
Because of this issue the phone become almost useless while traveling
Or while going up and down in my office building.
I haven't rooted it yet. Is this firmware problem or hardware.
Please help

Some people including myself are having connection issues when gsm/wcdma auto mode is selected...phone is stable when gsm only is selected..after comparing with 2 other phones,i can confirm this behaviour dosent happen on their phone..and i have to sadly say something is wrong with my phone..why dont you do a little experiment..try selecting gsm only mode and see if your connection is stable..maybe you are having a defective phone like some of us here...untill today i cant figure out if its a hardware fault or some weird software glitch.

In japan currently wcdma is used. After disconnecting
I can only see upward arrow all the time until I reset data network.
This is bugging me big time now

Many people including me are having this exact same problem. I am suspecting the modem software, and hoping it will be fixed soon. But please note I also held hope for almost a year that GPS glitches in the first galaxy were fixable with software, and now we all now it wasn't.
I'm having the EXACT same problem! Out of nowhere my 3G connection is 'lost?' and I only see an upward green arrow.. i have to reboot to get this right.. but after a short while.. same problem again!
I live in The Netherlands... I wonder what the problem could be, but even better! THE SOLUTION!!
Resolved!!!!!!!!
@mmichaell I got a great news for you. I could resolve this buggy thing.
Just dial *#*#9900#*#* this will open a pop-up
from which select Disable fast dormancy....and bangggggg the issue is gone..
let me know if you get it right
nope it doesnt work for me. ive also tried *#301279# trick but still problem is there!! wat should i do? return it? its only 1 month old, same connection works flawless on my nokia n8.
Hello everyone,
I own a Samsung Galaxy S2 and a HTC Desire HD. I am absolutely thrilled with so many things on the SGS2 but lately I've found that the wireless signal strength on my HTC Desire HD seems to be a lot stronger than my SGS2.
I've checked this holding both phones in the exact same spot connecting to the same router and found that the bars on the HTC always seem higher than the SGS2.
Thinking it just might have something to do with the way the phones were displaying the strength - I placed both phones in one location and found that the HTC was streaming music seamlessly but the SGS2 was losing signal strength and had to keep rebuffering and in some cases lost signal completely and I had to walk back to a strong spot and restart the wifi on the phone for it to pick up again.
Has anyone else been facing these issues?
Both phones are running Android 2.3.3 - is there any fix out there for it? I remember reading somewhere that this had to with Gingerbread on Samsung as this problem was faced earlier on the Samsung but after updating to Gingerbread the problem reappeared.
Anyone know if there's any fix for this to boost signal strength?
Much thanks in advance for any help offered.

Signal strength or inaccurate bars use tool to measure signal strength is the only measure of the wifi .

Thanks for the quick response - I will try that out.
But what I'm finding is the the current default wi-fi bars on both handsets seem accurate.
Holding the SGS2 and the HTC DHD in the exact same spot & streaming music from Winamp - the HTC plays the music uninterrupted whereas the SGS2 keeps losing the connection and has to buffer again.
I had seen some earlier threads that this was a problem on the SGS as well but it was fixed later. And then the Gingerbread update came out and the problem was back again.
Is this the case for anyone else. Seeing as they fixed it before is anyone aware of a fix for this to boost the wi-fi signal reception?
Thanks in advance.
Cheers,

Hi All,
I am having a strange problem with my S2 since last few months. I am from Mumbai, India and using Airtel network. There is a spot in my apartment which has very poor network reception of Airtel and I face issues whenever my cell is in that spot for a while. It happens that whenever I take my cell in that area, it starts losing signal bars till no bars are highlighted on the status bar at the top. It keeps showing zero bars but does not show "no signal" icon. Then, after keeping my cell in that spot for a while when I bring it in a better connectivity spot, signal bars start increasing and it appears that my cell has better reception again. However, if anyone tries to call me or I try to call anyone, they get "Out of coverage area" message or I get "Network registration failed" message respectively. I am having this problem since the day I started using Airtel and have tried a lot of remedies but only thing that works is rebooting my cell. I have tried using OpenSignal app to reset my connection whenever my cell comes back from the spot but even that fails to revive it and ultimately I have to reboot.
Has anyone faced such an issue and any ideas about a fix? Does it look like an issue with my cell or could it be an issue with my network provider? I would prefer not to root my S2 since I have 3 years warranty on it but if you think that it's the only way out of this, please let me know your opinion.
Thanks.
Sounds like a carrier issue to me. You pretty much said exactly that yourself when you said 'There is a spot in my apartment which has very poor network reception of Airtel and I face issues whenever my cell is in that spot for a while'.
That's normal in many buildings. Particularly if the network coverage in your area is borderline or poor. I have a similar issue in my house, in a few rooms I get no bars & sometimes coverage drops out completely, whereas in my loungeroom/dining/kitchen at the back of the house I get good coverage (for me, anyways).
You could try different modems, which might improve things. You don't have to be rooted to flash these, you can flash them using Odin. Tho it is easier to flash them with CWM if you're rooted.
I use to had the same issue with my 3 carrier at my desk in the office, and still on 2g services. I but since last month they already improved to hsdpa network added more bts and now my blank spot became H.
Yes you may try to change other service providers

Thanks for your suggestions guys. Yes, it might be only related to the carrier. But, I think that if signal goes down to zero and then when my cell is back in better coverage zone, shouldn't the modem take care of network registration by itself? My problem is that it doesn't. I have to reboot my cell every time after I come to know that my cell is showing signal bars but is not actually registered on the network. If I reboot my cell, everything becomes normal and so if it was just an issue with the carrier, shouldn't it continue like that even after reboot? If I think about it logically, I think following should help me out:
1. Try out a different cell for a few days and see if I face this issue or not.
2. If answer to 1 is no, then try out different modems on my S2 and see if that helps.
Actually, I just wanted to check if anyone else has faced this issue and figured out that something is not right with S2 drivers or something? That would help me with quick resolution of my problem.

Yep, your logic is sound ;-)
One thing tho. With regard to trying your sim out in another phone, you have to keep in mind the radio hardware is obviously different in different phones. And what that means is (and this is something I've observed on XDA), chances are you'll find the sim works perfectly in the other phone & you have no issues at all. This might be due to the actual equipment your carrier is using in the cell tower(s) you're close to, also the frequencies that gear is using might also be playing a part in your problems.
So definitely try it out in another phone & see what happens, but you could do worse than try out a bunch of modems in the S2 & see if that improves things.

Those are carrier issues, and maybe even the material of the constructions, in my house there are rooms where there's almost no signal at all, and in the living room it's ok, you should try to see in which tower you are connected maybe thats the problem
I have also had these problems on various networks here in Australia. If you don't need the data network, you could try using 2G only option. But that's not really a fix, is it? I suggest you try a pre-paid SIM from another network provider, to test them out first, before re-contracting.
Good luck. :fingers-crossed:

Yes, I was also thinking about it. It could be the combo of cell tower and S2 that are not liking each other that well.. And, if that's the case, I really hope that the issue can be resolved by switching modem drivers. I will have to do some what-ifings to nail this down now.
I like the other suggestion by HotrodHarry on trying out 2G only option - not the best way out but will help me in zeroing down on the cause.
hi people,
I have been using my galaxy SII i9100 for almost a year without any problems. As my guarantee was about to be over i gave it to the place i bought it for a general check up. They gave it back after that saying it seems fine. A day or two after I got it back my phone started showing very poor signal strength. when i'm out it shows 4 bars at max and at indoors it shows two bars to no signal at all. I gave it to repair again ( guarantee over by this time) n they say that the PCB is faulty and asking for 1200 AED ( around $320). So what i want to know is, are they asking too much cos i can almost get a new phone with that money and is there any way to fix it by myself and is there a chance that any other thing maybe causing the problem. Please help me. Thanx
Hello all,
I started to have some problems with signal strength.
It's not ROM-related (currently the newest CrDroid).
If I cut my WiFi and set the phone to prefer LTE signal sometimes I'm not able to use data. It's constantly switching between LTE / LTE+.
Sometimes it will connect and it's fine but most of the time it isn't.
It only happens in places when the signal is poor.
If I set the phone to prefer 3G it works perfectly normal.
My gf got the same phone and didn't experience that issue.
I believe that for some time after I received this phone it worked normally.
Maybe it's firmware related issue?
I heard about an issue with the poor signal on this phone...
Thank You in the advance for your answers.
