I have poor signal and bad reception with my galaxy s2
baseband is KI3 , I live in the philippines, where everyone around me will have full signal but my phone will have none or 1 bar. I have flashed different radios, it has made no difference.
ideas? Is it a radio problem? I dont even know what radio it should be on.
Logic says use same radio as those around you .

Change your modem, popular ones include KI4, KI1, KL1, and other older ones. Try them see how it affects your signal and if it's poor try another.

None of these seem to increase signal, could something be wrong with my phone? Its just like the signal is weak, outside its fine, but inside it doesnt pick up very well compared to other phones, its always no bars or 1 bar.
are you triyed change modem?
Are you using any case or cover that may hinder the antenna
I have a case but taking it off makes no difference, the signal goes from no bars to 1 bar, and shows edge, while other phones get full bars and 3g
Removing the case for me made remarkable improvement in signal strenght
I have so much trouble with the phone, im ready to get rid of it. It makes no sense that other phones get full bars while this expensive phone gets 1 bar or none and drops calls.
Also it never picks up 3g hardly, while other phones will be on 3g solid.
Its as if the antenna is weak

I am losing a signal half way through a conversation and i get cut off ,i have checked it a few times today by calling mates when the phone strength is 2-3 bars ,after a few minutes i get cut off and the phone has lost signal .
Any help with this please ?
I have looked at radio codes and flashing roms but unsure as to what they mean or do ,i am on O2 and the signal is ok where i live and worked ok on my last phone SE k800i ,just seems as though the hd2 is constantly losing the signal and trying to find it but them comes up with 2-3 bars
I am new to all this stuff so please explain it to an idiot in simple terms
If you are having signal issues, flashing a new radio could do a lot of good. The radio ROM is the software that controls how your phone connects to the various network signals. You may have to experiment with several different radios before you find one that works well in your area. Read THIS thread for more information on it.
Another possibility is if you are only experiencing signal problems during calls, it may be that you are holding the phone in a way which degrades the reception of your antenna. Some users have reported that holding the phone tightly at the bottom (where the antenna is located) causes a slow loss of signal. If this is the case, try gripping your phone nearer to the camera at the top.
Cheers for the link ,will have a read through
+1 faelock. if you hold the phone with the bottom pressed flat into your palm it can make a difference of as much as 2-3 bars.
Does anyone know if these make a difference ,as i have trouble with signal around the house but full signal while outside

I've seen those sold for years, but I really don't know if the boost signal. I used 1 once that came with a combo thing I bought on ebay, but didn't have signal problems to begin with.
You could look for signal repeaters that can be purchased that boost signal in the house. Over here in the usa, I know that sprint and at&t have them and you can get them free if you complain about signal strength in your house.
Those "signal boosters" are about as effective as kinoki foot pads and ionic bracelets. I had the same problem when I frist bought my phone. No signal or 1 bar in my bedroom but walk outside the door and I got 2-3 bars. After flashing a new radio I now have full bars everywhere in my house; so that would be my suggestion. If you're nervous about flashing and would rather go with a signal booster than check out THESE ones that apparently work.
Thanks for the reply guys

Not nervous about flashing a radio just a bit unsure as there seem to be so many to chose from ,are there any specific ones i should be looking at ?
Checked the prices on the signal boosters you mentioned and over here in the uk they are a lot more expensive than in the usa

the best way is to just test them out. What works for me, might not work for you. Since you have the Euro HD2, I'm pretty sure you can use any of the radios out, .50 and .51 radios.
How is your 3G reception on the Vibrant? I just purchased a Vibrant as a replacement for my aging and bluetooth handicapped G1 and I am disappointed with the 3G reception.
T-Mobile's coverage in my area is moderate, and the G1 has been able to hold on to a 3G signal in most locations. Typically, at home the G1 will hold on to 2-3 bars of 3G, and at work I am lucky to get 1 -- usually camps out on 2G with 4 or 5 bars.
The Vibrant pretty much always shows 0 bars of 3G while indoors, and may even flop back to 2G. It is fairly consistently on 2G in my home at 2 bars and at work I can only get 1 bar of 2G with this phone and spend the majority of the time with no signal at all.
I sat down and did some comparison between the Vibrant and the G1 and have found the following:
1. *#*#4636#*#* menu shows significantly worse signal levels on the Vibrant than on the G1, often times showing 0db and 0asu in the same location I am seeing -89db to -101db 3G on the G1.
2. The service menu on the Vibrant indicates a signal level which on 3G is fairly consistently 8db better than the one shown on the info menu. Interestingly, 2G signal levels as shown on the service menu seem fairly spot on with those shown from the info menu in Android.
3. The service menu 3G signal levels on the Vibrant seem consistent with those that I see on the G1 with a variation of perhaps only a couple of decibels.
That said, it seems interesting that battery usage on the Vibrant seems to indicate nearly 60% of its time with no service under cell standby when I get 0% in the same location with the G1. I am wondering if the time being recorded here is in fact the time spent with 0 bars being displayed even if the phone does, in fact, have a signal.
It is apparent that there is at least a software issue with the display here, as has been concluded in prior threads. However, ignoring the bar display I am wondering what others feel of the signal coverage with their Vibrant versus their old phone?
Does anyone have any experience with any of Samsung's other phone offerings? Do you think Samsung will post a radio update for this phone or possibly release one along with the GPS Fix/Froyo update in September?
I work in a position which requires me to be on-call a certain times during the year, and I can't really afford to have a phone that camps out at 60% no signal. I am really looking for reasons to keep this phone, as I like it otherwise, but practically, I need a phone that is going to receive phone calls. Any objective indications anyone can give that Samsung will continue to support this device may help sway my decision to keep it. My 14 days will be up on Thursday, so I need to make a final decision about keeping this phone before then.
Also, do any developers think that modifying the handling of the signal display in Android will cause a change in the amount of time the phone spends acquiring signal between 3G and 2G, or is this something that is purely handled within the radio firmware? If this is changeable, is this something that can be included in a future custom rom?

I made a call in the BOONDOCKS of NC, in an old river mill with 22 inch brick walls... NOBODY else was able to place a call other than me (all the big networks and nice phones).
I have pretty crappy 3g service here in new rochelle when at home the phone keeps fluctuating between 0-4 bars for 3G and the data speeds very inconsistent. Sometimes it even falls back to EDGE! This is pretty lame, i called t-mobile about it and they said there nothing they can do! If i am unhappy i should return the phone.
I live in NYC...
That is really all I have to say.
3-5 up speeds
constant 3g connection
The bars on the phone are funky though they look like there are none but you can still make calls. Its just the software is off just like the battery percentage.

If you're at home why aren't you on WiFi?
Seriously it's the most puzzling thing ever. 3G or not, I wouldn't be using it at home. Are you trying to replace your ISP with your phone or something?
You should do a search. Are you aware of the fact that -0dBm is impossible? The bars are off on this phone and the G1 is mediocre overall. It can hold on to a 3G signal for longer because your hand isn't blocking the antenna but the antenna itself is truly mediocre in fringe areas. Move your hand away from the bottom hump on the Vibrant. A lot of questions you're asking.. you're answering yourself.
I am not all too impressed with 3G coverage here at my home, but I mostly blame the network at my location and not necessarily the phone. TMO has spotty coverage near my house....period, and I live less than a mile from the tower. I have a Blackberry 9700 and it has similar issues with 3G. I've called and complained and they give me the usual "you're green on the map...return the phone....blah blah". I was closer to downtown Dallas yesterday and the phone had full bars and never got higher than -80dbm. Speedtest app showed about 3mbps downloads on average. I wouldn't say it was stellar but it's nothing like at home either. Only thing is my phone never automatically drops from 3G to E unless I am making calls. Once again the Blackberry 9700 does the same thing.
However, I am not completely convinced the phone isn't to blame either. I had a week with the new Motorola XT720, aka AWS Motoroi/Milestone that Magenta is/was rumored (who knows?) to get, and if Moto hadn't skimped on the CPU/RAM/screen/app memory of that phone I would have kept it instead of this Vibrant. That phone seemed to get much better 3G signal and HSPA was excellent compared to the Vibrant. I'm lucky if the Vibrant gets HSPA here at all. Overall network performance just seemed faster. It was quite obvious when I powered up the Vibrant the first time that 3G coverage is going to be an issue at my home with this phone.
FWIW my wife has an iPhone 3G which gets great 3G coverage here at the house on ATT. So I borrowed her SIM to test after I unlocked the Vibrant and it didn't make much difference. It did get 3G which I didn't think was technically possible until I saw that this phone has 1900 3G support as well as AWS. I do think the bars and definitely the battery indicators are not accurate whatsoever. I use Battery Indicator Pro and it's definitely obvious Samsung needs a software re-work.
Just because you live within 1 mile of a tower doesn't mean it's 3G or that there isn't something in the way of it's signal and your house.. I live within 1 mile of a tower and it's not 3G. It's supposed to get 3G soon.

Maybe I don't have WiFi in my house?
Maybe I would love to reduce my monthly expenditures by the $60 I throw away to Comcast?
I am well aware of the fact that -0dbm is impossible. This is simply what the phone is displaying. I also agree that the G1's reception is mediocre, but this phone seems worse than the G1. Blocking the antenna with my hand doesn't seem to make much difference on either the Vibrant or the G1.
I asked for objective answers to my questions which basically boil down to the following:
1. Do you think Samsung will provide support for the software on this phone (including the radio) over the long term ie. do you think there will be upgrades in this department?
2. Do you think this is something custom rom developers can address purely via modifying the OS?

You're asking questions that we can't answer. Do we work at Samsung? No. Would stock Android fix this? Maybe.
It seems worse than the G1 because based on your comments the bars are having an affect on what you deem to be "worse". I've had tons of T-Mobile phones including the G1 and the Vibrant is not considerably worse than any. INFACT it will hold on to a 3G signal for longer than most. My CLIQ displayed 3 bars as -105dBm. Accurate? NO.

I know that nobody here is working for Samsung but there are plenty of people here who have developed for Android, and the question I am posing is if this is something that can be addressed in a custom rom.
I think my original post makes it clear that there is obviously a software issue with bar display, but I am wondering if this software issue is also causing the Android OS to force a switch to 2G in an instance where the G1 with a properly functioning display would keep 3G. ie, the phone is switching to 2G early because it thinks it only has -111dbm when it in fact still has -103dbm. I am not clear on whether this functionality is performed within the OS itself or purely within the radio firmware.
My hands are rather large, so holding the G1 basically covers the entire rear of the phone. The antenna is near the top of the phone whereas the antenna on the Vibrant seems to be on the bottom. Though holding both phones in various positions seems to have little effect on the received signal strength so far as I can tell.
The time spent without signal in cell standby I believe to be erroneous. I think it is tallying up that time any time there are zero bars, even if the phone still has a signal. This makes it very difficult to objectively compare the 2 phones. If the OS is in fact driving the switch from 3G to 2G this may explain my poor access in fringe areas as the phone will be constantly flapping between the two. If the functions that drive this behavior are within the AOSP source this could easily be something we can fix in a custom rom even without Samsung's help, even if a radio update would be ideal.

I can wrap my hand around the phone (Vibrant), either top, center or bottom and I do not see any change in either reception, call quality, network throughput or number of bars.

It is perfectly understandable that if he has good reception with a G1, an older phone, he expects at least a similar level or reception with a newer, higher end phone. WiFi would be considered a workaround.
I just received my Vibrant on Monday and it's sadly replacing my amazing Nexus One. I've noticed that the Vibrant antenna is AWFUL. Where I received 4-5 bars on the N1, I'm getting 1-3 bars now and it even goes down to Edge once every few hours.
Like the OP, I've been monitoring the db levels and they're frequently around -95 through -107. While my calls don't actually drop, the quality does get worse. I'm also getting many 3G connection errors when trying to browser or download apps from the Market. It's quite disappointing. The phone is made of plastic as well, so I'd imagine that the antenna reception should be better.
Being that there are only 2 pages on this particular thread, does this mean it's a fluke and others' phones are ok?

4-5 bars on a phone with a 4 bar scale?
Stop looking at -dBm on the Vibrant, it's not accurate.
If you don't want the phone to switch to EDGE lock it on 3G.

Thanks. 3G is spotty at best in the Des Moines Area, so I'll leave well enough alone.
So, in follow up to this, I had downloaded and installed RF signal tracker from the market and went driving around until I found a tower. It seems that via Android OS the best signal strength received was -81dbm and that was sitting right next to the tower. The phone stayed locked at -81dbm for a few miles down the road so I suspect this is peak signal on this phone which should really be something like -65dbm. I think this pretty much confirms that there is indeed a software issue with the signal display.
I also took some time looking at Android code and found that the bars are driven on GSM/UMTS by asu as follows:
if (asu <= 2 || asu == 99) iconLevel = 0;
else if (asu >= 12) iconLevel = 4;
else if (asu >= 8) iconLevel = 3;
else if (asu >= 5) iconLevel = 2;
else iconLevel = 1;
So figuring up the dbm values from these, I went ahead and created a new asu scale which is adjusted -8dbm from "normal" since this seems to be the worst case of the mismatch between the phone firmware and what Android is reporting and applied that within the market app Real Signal to try and get an apples to apples comparison of signal bars between this phone and the old G1. Unfortunately, the degree if miscalibration means we can't set a negative ASU so we don't get any meaningful display on Real Signal until we hit the 3rd bar. In doing this if I go to a moderate overage area I am seeing the bars I would expect.
After my little drive with RF Signal Tracker its actually pretty clear that discrepancy is really more like -15dbm, which adjusting the figures should mean that this phone in reality gets slightly better reception than the old G1.
It seems we should be able to workaround this in a custom ROM by doing one of the following:
1. Modify getGsmSignalStrength() to add the -15dbm to the returned signal strength value(hackish).
2. Modify the vendor RIL to compensate for the -15dbm offset when on UMTS. (Probably the proper solution).
I'm not clear on whether the vendor RIL code gets posted to AOSP...

I haven't done any detailed tests but I can state that in real world use, I am not happy with my Vibrant's reception. My G1 was very noticeably better at getting and holding 3G and Edge connections in the same locations where my new Vibrant won't.
Next to a tower on GSM(GSM/GPRS/EDGE) you should see -51dBm at the most with Android. W-CDMA is different because they really don't use -dBm to determine signal quality. They use power/noise.
Does any1 notice their signal going up n down frequently? No matter what network sim its up n dwn. even when i know that it should be full signal it fluctuates massivly. sometkmes shows no signal yet im blazing away on the net
Yes, this is quite normal with Samsung's Android handsets.
Their signal meter seems to (under)read quite a bit. Regularly I'll show no plausible signal and still be ok to chat / surf etc.
The SGS did the same trick, so I don't think its anything to worry about! (and the signal quality & stability is much better on SGS2 than on SGS anyway)
i was thinking that i may have a faulty handset, hmm it can be sat ther full H then the next second its 1 bar G
happens to me too. Also, my SGS2 always say 3G until I open a webpage then it says H. My SGS1 was always on H.
i thought this would be the best place for a problem i started having about2 weeks ago. i am on vodafone uk.
i used to get 3-4 of the 4 bars reception while sitting at home(as an example). suddenly i was getting 1-2 and sometimes none (all blank).
i thought i would try and eliminate things one by one so here is what i did...
checked with my sim in another phone and another sim in mine. from memory the other phone having my sim was slightly down but not much and my phone with the other sim didnt really change much.
i checked with vodafone by calling them, they said they couldnt see any problems on the network, birmingham uk, but would send a new sim, after getting the sim activated when it arrived, no better. their onling forum is still waiting for a response back from their technical whether there is any problems. i dont see how the phone department can instantly tell me when the technical need many days to find an answer.
i thought it could be the rom so i first updated lite'ning rom to resurrection remix and then to a later version of RR and no change. the newest version of RR has a different kernel, flux i think, than the siyah in the 2 previous roms but again that different kernel didnt improve it. lastly i even changed the modem/radio trying to different ones to the default, xxlpx and kh3 and again no difference.
the only thing that improves it is turning 2G on instead of 3G. the bars go back up to 3-4. even with 3G on previously as i never changed it before it was always fine.
i know this is a long post but i wanted to be thorough as i really appreciate any help as i am now lost as what could improve this.
Mispost
anyone?
I have been having a similar problem on Three for about five weeks now. Despite numerous reloads of Android and modems etc I was getting no results, 5mb dl speeds have dropped to around 150kb despite having a good signal.
After many many calls to so called customer service I have discovered that a new cell tower near to me has been activated as part of the network expansion program and because this cell is closer to me than the one I used to connect to I now get a stronger signal from this so my phone always chooses this. Problem is this cell has only got a 2mb feed INTO it, its a TMobile/Orange cell now being shared with Three....so I am basically fooked.
Check with Vodafone if they have done anything similar recently near you. Three are adamant there are no problems my end, technically they are correct I suppose, its all working, I just cant access the net without it timing out constantly now.

I am having the same issue with my phone. I get only one bar (sometimes none!) whenever I'm home & I'm on WiFi; however, I get full signal strength when I'm out & on 3G.

i thought it could be the cell tower thing as there is only 1 vodafone one in quite a large radious, about 2 miles, and many of all the other networks. i dont know why vodafone are happy to have 1 compared to at least 3-4 each for all other providers.
this morning i drove that 1 mile to the vodafone mast and ran fresh network and surely that would have connected to that as i was 5 meters from it. still no better. ??
Just try NELP3 modem once... I had done similar issue once.. Now my network is better..
is nelp3 okay for uk though?
Try flashing another Modem. Im from Germany but i had similar problems. A new Rom would do too i think

i do have the same problem as above, no signal in the building and 50% signal outside building. I swithch my SIM with fren's (he use another telco), and his SIM not work on my S2 and my SIM work on his phone (not SIM issues).
I tested many modem as recommented , LP2/LP3, LP9, LPX, KI3, KI4, KF2, no luck.
I flash different ROM, (some old version that work before), from CM9, AOKP, Sammy. no luck.
I restore old back up ROM. no luck
Fix permission, no luck.
any advice ?
OK next step is to flash a different modem

i've tried a few modems including the ones people believe better, all have this problem so far.
it may be the network mast in my case. i discussed with vodafone what 3G mast i was connected to and then which 3G mast is next closest. i then went right next to that other 3G mast and the signal was full bars, no fluctuation at all. this surely means it is either, 1-the network mast i keep locking to having problems or 2-all the modems i have used favouring battery over strength and not getting enough power to get a good signal.
is there a way of finding out which modems are better for battery and which are better for signal strength?
Umm not that I know of, best thing to do for that is either research the modems for better strength or battery etc, or just test some yourself, however that is time consuming,
Personally I think it is just the mast having problems, however I may be wrong

i thought i would add a little research to this thread, not too much but just my experience with 3 specific modems.
the background is that recently i have started getting very poor network signal as i believe the closest 3g mast to me is having problems. if i turn to 2g its better as the phone then connects to the closest 2g tower which gives better network signal.
i know that a modem should be left for 2-3 days before judging but i thought that if a modem is currently better than another then that is only likely to stay the same with time as long as they were given the same short period of time.
i used the app network signal info and did 3 5 minute tests for each modem and then averaged the percentage of the signal and also averaged the -dbm also.
i first used the modem i currently had on there, BUKI1
- average percentage was 19%
- average -dbm was -103
both very poor scores
the signal was very jumpy up and down also
i then flashed the custom modem, i think by krs007, M250S
- average percentage was 44.6%
- average -dbm was -90.66
obviously a huge increase
the signal was very steady, hardly changing from that average
lastly i flashed NELP3
- average percentage was 30.66%
- average -dbm was -97.33
better than at first but not as good as M250S
i am now going to let M250S bed in for a few days while keeping my eye on here for how NELP4 performs but so far i have a huge increase in signal in a previously very poor area. as this is also due i believe to the tower having problems, hopefully it will only get better.
Try downloading OpenSignalMaps from Google Play Store. For starters, you can determine the approximate location of the offending cell tower (if the cell tower was indeed the culprit). Sometimes, i realise that the phone tends to stick to certain cell towers when others are in closer range and could purportedly provide a better radio link. For this, the app provides a refresh feature that allows you to manually trigger a cell tower refresh. I am aware that most apps requiring connectivity have this feature but i don't suppose you can call the refresh on trigger.
Hi Marc
Tracked down a copy of M250S(dont know if its the same as you have installed though), and very briefly, as in 30 secondsish, I had 4 bars and dl`s around 5mb again!.But midway through it dropped out and that seems to be the pattern. Seems to be having problems locking onto a cell, signal bars frequently grey out, maybe its a compatibility issue with CM9, I dont know.
Anyway, let us know how you get on,
Cheers
Chris
it probably is the same as i dont think any others have that name.
it probably just needs to bed in for a few days. i have noticed mine go between 3g and H quite regular but it always does that, i havent had any dropped calls or similar so far.
So almost after 3 weeks of getting the TS I decided to put in my AT&T SIM. I was reluctant to use that tiny bastard screw driver but I did it anyways. I have noticed that the network signal strength of my watch is almost non-existant. It will get cellphone signal at only certain place. With the same sim card on my phone (Nexus 5), I get good cell reception.
How are others doing in this department? How's the cellphone signal? Is there anything I can do to improve the mobile network signal. Currently I am on stock with Loki's security patch.
I am not sure if this is a hardware issue or software issue. I remember someone opening the TS and checking the antenna. Any suggestions would be highly appreciated.
Some information on my TS -
North American 1/8
Stock ROM with Loki's patch.
Ok here is my observation:
I could not get signal inside my office, home and costco
I did get signal once I get out of my office - full signal bars with H+. I made a short trip from office to costco and home and back to office. It was able to get signals when I was driving but in some areas where I used to get 2-3 bars in my phone, TS did not pick at any signal at all. So mobile network signal is working but it is pretty weak compared to my phone.
May be it needs some tune up
i have the same problem,the signal is low and TS really has a hard time to find one,if its lost
can we do something about this ?
I opened mine just to have a look and found one of the connectors lose, took a bit of fiddling to get it back on but my network signal seems as good as my note3.
I don't know why, but after installing this app.https://play.google.com/store/apps/details?id=com.misonicon.signalbooster3g4g
The signal works perfectly, I didn't believe in this apps but now I don't know what to say
At least it works
Mobile frequency fluctuates on my end too, made sure APN settings are listed exactly like they say here on the forums, maybe I should change to another GSM 3G SIM card?
