GSM signal sensitivity matter of S II - Galaxy S II Q&A, Help & Troubleshooting

There was a problem with my SII. I returned it to Samsung and they made an upgrade to something they didnt tell me.
The phone now works as a GSM normal phone also. The reception is great. 3G and H is available as my previous phone
Please close the thread
Thank you all
Dear all
After reading a lot the threads I decided to make this post. Sorry if this matter had been answered somewhere else for this phone.
Before I had a TD2, later a Nokia 5800.
I bought SII before a week
When I go to the places where I had GSM signal or 3G, I noted that with the SII the gsm signal is comperative with my old phones very weak (TD2 better than 5800), even not existing.
Many times I am not able to operate the phone at all since gsm is missing.
Seems like there is a lack of sensitivity to the gsm module of the SII.
I 'm using the factory 2.3.3
If you think that there is a software or ROM that can make more sensitive the phone please tell me so
Beyond that the phone is great

Seems that is only me having this problem

network??
is the gs2 on the same network as your previous phones??
take it back and say its faulty?
i dont no mine is a great signal except for where my network provider says it isnt luckily for me thats at home so no signal at home for me lol

Of course its in the same network, my home, my office is at the same place..... hopefully
The reception of SII lacks from 5800 which is worst than TD2,

The SII stopped recognizing the SD card....
So I returned the SGS2 to the service of Samsung. I 'm gonna take it back in a week.
Meanwhile I use my old Nokia 5800, which, since I go to the same places again and again it really has a much better signal and almost never looses the 3G or H.
Comparing to my damaged i9100 it has a much better reception in GSM.
I will let you know when Samsung returns me my phone.
Since I was looking a lot for the reception problem in the internet, mostly I read that there is also a low reception of the Wifi, which I didnt notice....

Just Got My T-Mobile Vario, Love It, But NO Service!!

I just got my cell this week and was dismayed to find out that the phone would get absolutely no service in my house. I was able to make one phone call, once.
Is there any product I can get to boost my reception from zilch to at least one or two bars?
I'd hate to part with this amazing phone...
unfortunately i have this problem also. I dont know whether its t-mobile or the fone but thats why i got a house fone.
hehe
Look for external antenna thread in this forum.
that would be tmobile uk
previously known as one2one or none2none as it was popularly called. i live in central london and their reception is still flakey compared to my vodafone connection

[Q] Not able to connect to Internet

Wondering if you can help me.
In my office my colleuge and I have an hd2 on UK o2 pay monthly. Untill about a month a go we were getting HSPDA internet access. Now we are only getting EDGE. I contacted o2 and they stated that the area is a very high coverage area and we should be getting HSPDA.
What makes matters more interesting is two other colleuges in my department in the same building, one has an iphone 3 and the other has an iphone 4, both guys are on uk 02 pay monthly and are getting full 3g access. I am getting 3g and hspda in other areas.
Does anybody know why we are getting edge instead of at least 3g?
thanks.
I had a very simillar issue, so perhaps the solution I found will work for you. A co-worker of mine bought an HD2 (immediately after seeing mine). In many areas at work the reception was terrible. I also noticed that at home, when I first had the phone I got 3G often, but after a few weeks I was suddenly stuck on the EDGE network (If I got any reception at all). Since messing around with the Android port I was forced to flash a new Radio ROM and it seems that was my problem all along. At home I now get constant full bars HSPDA. At work I get reception in places that I never did before. My coworker (still using stock radio) is having the same reception issues I used to have.
So my advice is try a few different radios and see if that helps.

Yea we did try that the other night thinking it might be a radio issue we went from 2.5 up to 2.12. What rom / radio did you use if you dont mind me asking?
Does anybody else have any ideas? This is happening with two ok uk hd2's in the office! My colleuge and I have tried multiple rom and radio upgrades but nothing is working but my other colleuge on iphone can get 3g sitting beside me
ive had this issue too, never knew how to fix it :/
AGHHHHHHHHHHHH Going to call o2 tomorrow and tell them I want to swap for a new phone, I am not getting the service I should be!!!
Ive tried just about everything I can think of. Ive tried updating the ROM, Radio, rilphone.dll - also tried going back to stock rom, yet my colleuge sits on his iphone right beside me on 3g its madness!
have you tryed puting your phone into flight mode then .ack on again let thephone pick the strongest hsdpa mast signal up. welcome to tbd way o2 works lol we get it all the time in york and leeds
That is a very interesting idea. I will try and report back thanks man!
I am really getting no ware with this. Phoned O2 and they tested phone in my network said that I should be ok I should have full hspda access, my colleuge is sitting on iphone with ull 3g and has a o2 dongle which has hspda access. I am getting fulll signal strength, changed the sim card and tried multiple radio and dll file combos and this is driving me nuts. Any help would be appreciated.
I have been doing some further testing and found something interesting. When I am at home and can connect to HSPDA. I went into the base band and changed it to WMCDA got full access. I then changed it to GSM band and got Edge. I then went into work to test it and tried to force it to WMDCDA but it wouldn't even connect at all no coverage.
I tried it back on GSM and full coverage but only edge support. Any ideas?

[Q] UK GS2 - rubbish without WIFI

Hi there..
I am generally very happy with my S2, which i purchased from Phones 4 U in England, and is using Vodafone sim.
I am a noob unfortunately, but i do know what Wifi is, and i know that when i am connected to my home wireless network, i can browse online (stock or dolphin browser) use the FB app, and marketplace etc all nice and smooth.
The problem appears to be when i am not connected to a Wifi network, it is usually very very slow do display data, and more often than not, it will say "unable to connect", or "there was a problem".
Also, how important is the fact that i bought in the UK? my phone says..
GT-I9100
2.3.3
I9100xxKE7 (baseband v.)
(kernel v.) 2.6.35.7-I9100XWKF3-CL276555 [email protected] #2
Build number GINGERBREAD.XWKF3
It is a great phone apart from when i'm out and about data is rubbish! I am on a £36 a month contract.
Google maps/navigation also slow to find me. maybe cause i'm in the countryside at the start of my journey?
many thanks for any help from geniuses and sorry if this answer is well known/ already there... it's just that many questions seem to relate to korean/US/non UK versions. regards
You mentioned you are in the countryside, chances are the signal is bad it's always usually city's who have the best signal i highly doubt it's anything to do with your SGSII.
ps - i purchased my SGSII in the UK and have never had any major issues with it.
Wow, back to basics eh? Well, the speed of your mobile network depends on the coverage in your area. Generally if you're in the UK countryside, you're probably looking at GPRS, which is painfully slow.
Go to http://www.vodafone.co.uk/vodafone-uk/personal-coverage/ enter your postcode and choose "Internet and email", if it's "Slow speed", that's where your problem lies.
It's not a problem with the Samsung Galaxy S II, or with Android, it's probably a problem with your network operator.
im on the london/kent borders, can only really get 2g in my flat but outside the signal is fine. like others have said it will be because you are in a rubbish signal area, or you have put the phone into 2g only mode. Also you cant compare your wifi speed with normal signal speed. Until we start getting 4g rolled out it will always be slower
well many thanks for quick replies. The vodafone signal map thing states that i have yeah either variable or rubbish signal. I knew this would be the case around here... just well... thought my Galaxy was some kind of nex gen super phone. Just what kind of network do Voda think they're running here man?
Cheers guys

Reports of dropped calls and poor reception

Have you noticed your G6SE is dropping calls and has overall poor reception?
I've had mine for four days now and have dropped many calls and lost signal where my previous phone managed to easily retain the network and never dropped calls.
Also I noticed when connected to my car's bluetooth, the signal display never shows full strength where again my previous phone always did. The GS6E only ever shows 80%
20150424_222933-1 by markcaigerwatson, on Flickr
when looking at my signal history in gsam, it also never goes above 80% which ties up with what my car's display.
Screenshot_2015-04-24-22-15-33.png by markcaigerwatson, on Flickr
Now i've made a comparison between my M8 and the GS6E and this clearly shows the GS6E is less sensitive to cell reception and this equates to the dropped calls.
The M8 can achieve -69 dBm at one one one point
Screenshot_2015-04-24-22-52-42 by markcaigerwatson, on Flickr
and the GS6E a lower -81dBm
Screenshot_2015-04-24-22-56-54 by markcaigerwatson, on Flickr
Ok, so the GS6E is not as good as others at cell reception. Is this a hardware limitation? or could new radios help this?
What is your experience of this?
There are various reports cropping up now about this

Veedubs unite!
What country and carrier are you on?
I'm in the US and on sprint and drop calls like crazy with my gs6e. Never had this issue with 10 years on sprint. I've noticed that I seem to drop calls more frequently while travelling on 9 at high rates of speed. It seems to be a tower handoff issue. I don't have the issue whilenjoying stationary.
I'm on tmo (US) and no issues. Honestly I've not read a lot of complaints about cell reception or at least no more than usual on any device. Regardless of that why I chimed in was really to say that my first phone was defective. The issues I had (horrid batt despite trying every fix mentioned here and all across the internet, fingerprint scanner was about 50%, again tried every possible fix I was able to scour up. New device and the fingerprint scanner immedietly worked perfectly and my battery life was fixed without me doing a thing. Keep in mind that by fixed battery I mean I get about 4 hours screen up time which isn't good but about what I would expect for a small battery in a bloated device.
Long story short, consider exchanging it. The lack of reports that speak of bad cell reception imply you may have a lemon to me.
Did you click on any of the links I posted in my original post? There are more too, but i thought that was enough.

Yeah love the VeeDub!
I'm in the Uk on the 3 network...
Here is my wife's 2013 Moto G next to my 2015 GS6E. She is also on 3. As you can see the Moto G performs much better than the GS6E. Moto G on the right obvs. It was also £500 cheaper!

Definitely some poor signal reception on Galaxy S6 Edge. Mine has poor signal reception as well. Bought mine unlocked in Hong Kong model 9250.
If I tell one of the people in HK about this they will give me the same old lame answer that no one has complained about thus issue yet.:silly:
Poor reception on China Unicom in China, poor reception on CHT in Taiwan and poor reception on CSL in Hong Kong. Last but not least is Wifi reception is literally horrible unless you sit or stand right next to Wifi router!
Yep I'm having the same issue with my S6 Edge to. At first I thought it was my network (Three UK) but after doing some research, I'm reading the issue is more widespread, internationally 2. Calls keep dropping when I'm on a call and I'm getting a bad reception in places where my S5 didn't. Really not happy about this. I hope this issue can be fixed with an update.
Experiencing the same issue. I put my S6 edge, old S4 and iPhone 4 + 5s side by side and they all have max signal while my Edge had just 1 bar.
I've been researching and somehow got to the Sprint forums where they were also reporting the same problems. I saw there that you could try switching to CDMA only. Tried it and while it did improve the signal, it prevented me from using LTE which I'm not really willing to compromise.

Got the same problem here in Oz. btw what app is that showing the signal strength?

Samsung really needs to get this fixed ASAP as this could ruin the Samsung Galaxy Brand.

it is called Network Signal Info.. Free from Google Play.
This is in México City full LTE with my Note 4 , but the EDGE has This really poor reception.
The Phone is faulty or is the same case as others report on signal issues?
Same here for me on EE in the UK, switch to 2g/3g and signal is fine, set it back to 2g/3g/4g and 1 bar
Not sure what the problem is with this Galaxy S6 Edge but the 4G LTE reception is poor and download speeds are slow.
Same for me. I m in France near strasbourg with operator orange. It works fine with iphone but not with my galaxy s6 edge! !! With the same sim card of course!
Sent from my SM-G925F using XDA Free mobile app
I have not been able to connect to LTE since I got the edge a month ago. I'm currently on OE3 if this helps. Could this be a hardware issue?
I have received a few updates on my Galaxy S6 Edge but until now the wifi reception along with 3G and 4G reception suck. Even when reception is great or average the download speeds suck and are about half of what they are on my iPhone 6. Was expecting better results out of this phone but I guess not. My guess is that they either intentionally turned down the power provided for cell reception and wifi reception for longer battery life or their antennas on this smartphone really suck. Definitely a problem that Samsung needs to look into.
Mine is also struggling with connecting to stuff. 4g is spotty, calls drop and break up, wifi is shockingly bad, even in the next room to the router. 1 bar or no service on EE UK in a good signal area.
Going to call Samsung tomorrow and if they have no solution, it is definitely going back.
I am going to get rid of this Galaxy S6 Edge when the new Motorola comes out. The reception for both wifi and cell signal are beyond horrible on this phone. Battery life is quite poor as well. Try making a call using speakerphone if you have to talk while driving and see how many people tell you that you sound horrible. Samsung should learn a thing or two from Motorola,Apple and Blackberry when making phones for phone calls.
Samsung dropped the ball with this phone in two areas: Battery and Reception.
I am moving to a new phone as soon as I can sell this.

Network Signal İssues

I checked many forums on web and see a lot of people complaining about bad reception,call drops etc. on Galaxy s6 Edge
Also here there is 2 topic opened by members .I wrote one of them but no one gave me even a clue
My network signal really sucks, especially while on wcdma/3g mod. So one of post on web says Samsung had changed their anttenna system thats why.Some of says its about modem part.
Most of post wroten about in May and June so whats happened to this issue.How did you solve? Or what is the problem is it software or hardware related.
Thanks
I have a new 925F on T-Mobile in the US and I have also noticed this issue. Signal strength is much worse than on my prior device (HTC One M7). I have been toying with flashing the T-Mobile modem on my device and seeing what happens, but am afraid of what might happen...don't need a shiny new brick. I have tried several different ROMs, including the one from the T-Mobile sub-forum that is no longer being supported with the same results.
Anyone have any ideas, or know what would happen if I flashed the 925T modem on my 925F device?
like i said there is to possiblty causing this issue. Samsungs new antenna system or hardware problem.People were complaining about it a few months ago and ı am curious what happened their device or they used to live with it?
Have to say have the same experience... I actually carry an iphone 6 (for business reasons) as well - same network (AT&T), and without exception:
- the iphone has better reception in the same location (more bars, faster internet, more reliable internet)
- the iphone connects faster when the plane lands (and I fly alot)
- the iphone keeps reception in places where the S6 loses it
Frustrating, as I'm the opposite of an iphone fanboy, and using the phones next to each other shows me Samsung needs to do more work in this area!
The only reliable solution to SLIGHTLY improve things is to restart the phone a LOT
I have had to switch to 2g/3g only because my S6 edge has little or no signal on 4g and it uses about 3% per hour of battery on standby. I also have an iPhone 6 and both are on the same network(EE in the UK) and I never see anything under half bars on 4g but most of the time it is full bars. I have had the phone replaced and had two sim swaps but it is still no better.
The camera on the S6 is fantastic but the rest of the phone is a lagging stuttering piece of sh!t. I sold my Note 4 and Moto X 2014 a few weeks ago in preparation for the Note 5 but it is not sold in Europe. On the bright side the S6 is better than the G4 I tried for a few weeks.
today i went to service to ask replace the device, explained my issues after one hour they told me the problem solved by flashing new firmware i am sure the problem persist because i had newest firmware and flashed it before.So we have to live with it i guess its not a problem for them .
i have noticed that only Edge users complaining about it and not sure but i guess i read antenna is short on Edge.
