[Q] poor signal strength on Galaxy S - Galaxy S I9000 Q&A, Help & Troubleshooting

the signal strength on my galaxy s does not improve beyond -81dbm ... it degardes to -111dbm or so ..at times while speaking it goes in a silent mode .
is there any fix available or any likelihood of it being availble in near future .
i compared signal strength with blackberry phone at same place and same operator ....it was -67dbm.
huge difference ???
can someone help with suggestion or shall i sell this device asap.

yeah i got the same problems .. that really sucks .. :/ sometimes i loose signal completely

Different technology will always fair differently in various situation - meaning that the Galsxy will have a worse signal in some situation, but a better signal in others. If you are finding that you are not satisfied with it, best to sell it.

same for me its not better then iPhone 4 then...

somebody has to say it; "you're holding it wrong"

it goes to 105 dmb before 111
still have signal at 111
after that it goes to signal lost (tries to downgrade to 3G/2G before)
personally i've a hard time making it lose signal. when i already at -105 i can by covering it with hands then putting my hands in a box or covering on top with my body (yeh i look dumb when i do that)
otherwise i can't
for the GPS it's another story.. it cuts when you touch the screen sometimes..

Experienced poor signal strength myself, try using country specific modem when flashing via Odin, You can flash Modem itself to try out which one works best.
Tried flashing multiple modems on my phone and some seems to work better than other, could just be a placebo effect though o.o

does that mean it is a hardware issue or can this be improved by software upgrade..
Recevier senstivity is mobile's basic functionality , manufacturer's shall not compromise with this basic parameter .
I have checked signal strength at various locations but it never improves from -81dbm

Yeah, if you try and flash a CSC that's meant for your region may help.

Request if some one can help with procedure to flash.

Well not only your CSC but a newer MODEM file would help!

Also I've found if it will help you JPC modem so far for me is best in the UK on O2 (that includes testing quite a weak JPH modem file imo)

i would like to improve my samsung s1 android signal

How to Increase Reception on Sony Xperia X1

Did anyone tried this out?
http://blog.whitesites.com/How-to-Increase-Reception-on-Sony-Xperia-X1__633958291637656250_blog.htm
Better try to flash an other radio version before doing this to your Xperia.
Edit:
At home i have just 2 bars of reception, but anyway it has a very good connection. Only HSDPA reception could be a little more.
If i am outside my house, i mostly have full reception even with HSDPA.
If you're getting a weak signal from your provider, there's no way to magically make reception better other than the provider giving better coverage.
Being that my Nokia's all have full reception in house and the Xperia loses connection in the same location...

I've changed 5 times already.
The issue is not whether it can be resolved or not, it is how slipshod the SE radio firmware is.
Nokia gets it right 100% of the time, so why can't SE?
The blogger on that link may be onto something (ie hardware related, not firmware) - but I'm not going to do that!
I changed the radio f/w to 1.16 - it's better than before, still not perfect in terms of the number of bars, and I sometimes lose the signal in the local supermarket...
X1 signal quality is poor/below average - but not poor enough to take the phone apart like that, or to actually change it for another.
I have already re-shelled my phone, so I have no fear of this. It is actually very easy to get to that part, but I would think that the rubberized coating would help to prevent corrosion on the copper antenna. Correct me if I am wrong, but wouldn't a cell signal have no problem passing through a millimeter of rubber compound?
I would be more than willing to mod this to get a few more bars, but I don't want to cause damage and not actually have any benefit.
If anyone here has tried it please post your results.
i just did this mod so far there has not been any noticable increases in reception but it seems to be more stable with less drop outs

signal drop

I have a weird problem with my galaxy s. Normally my phone reception is strong and shows 5 bars but then sporadically it drops to 0 bars and I have no connection. This happens even when I don't touch the device. However I do notice that when I touch it the signal drops slightly. When I was in a train yesterday it dropped all the time. My father has the same provider as me with his iphone 4 and is not experiencing any drops so that shouldnt be the issue.
This problem seems rather recent after installing darky's rom v.7 and 8, but I'm not sure if that's whats causing the probem. Any ideas? I would hate to send back my phone. Could it also be a sim card problem for some reason?
Try to switch to GSM mode only.. I noticed my signal is about 50% lower if my network mode is set to auto instead of GSM mode.
the signal does seem a bit stronger you're right! thx for that
I'm not sure if it fixes the problem though because it could jump from strong signal to no signal in a split second..
Changed the ROM and got problems does that not give you the answer .
Cannot send back the phone as with a non standard ROM warranty is invalid .
I would flash back to Eclair via ODIN the use Kies to update to your providers current firmware .

well it makes no sense that changing a rom that works well for everyone would be a cause of a weird problem like this. I gotta say though that since changing the option that EarlZ mentioned helped and I haven't seen a drop yet, so lets hope that fixed it.

Does not work well for everyone if you read the multiple complaints .
Thats the nature of rom building a work in progress .
Easy way to test is as always to revert to original rom .

[Q] Best Radio - Samsung Galaxy S - Optus (Australia)

Hi,
I have a Samsung Galaxy S I9000
I am in Australia on the Optus network.
Can someone please advice of the best radio to use?
All my specs are in my signature.
How can i tell what I have and if there is a better radio how do i update it?
Thanks
Is there anyone who can help answer my question?????
Please
It's pretty difficult to quantitatively measure modem performance with the SGS. Unfortunately, most posts you would get about this will be highly subjective. I'm with Optus in Sydney and in my tests, I've found that the JVE modem is really good. Low battery consumption, fairly reliable 3G connection and fast GPS.
Others have reported JL2 is the fastest for 3G speeds, others still claim JPE gives the best reception. I've tried both and they're both good, I have no major complaints about either of them. Most recently I tried JQ1 and found the GPS really quick and accurate. 3G seemed to be quick and reliable, but I think signal strength reported wasn't as strong as some other modems. Battery life seemed good, but I think JVE was slightly better (possibly due to signal strength?)
Just test and compare for yourself. My shortlist would be:
JVE, JPE, JQ1, JPY, JL2
Further to that list, JPG seemed good, but it used to report my GPS position inaccurately when I briefly trialled it.
Today I had major trouble with JQ1 getting to download anything from the web, so switched to JVE and had some similar trouble. I'm guessing it's the network in my area. I might try JL2 again, as it's been a while and Whirlpool users report it as one of the fastest for download/upload speeds on the Virgin/Optus network, but I don't want to sacrifice GPS performance either. JL2 is a little older though and I've favoured sticking to more recent modems because I figure that Samsung are likely to improve battery consumption/reception/reliability rather than go backwards (although, never say never...)
Does that help?
Radio - Samsung Galaxy S I9000
Thanks for the reply...
It has helped a little but still am unclear.
How do I flash just the radio?
Where do i find it to flash it?
I find connectivity to be pretty good, but battery life sucks....
I also find that my current rom doesn't like even making calls in 2G, when 3G is not available...
Any thoughts...please

This is not related directly to your topic, but do you know what is the latest official stock firmware and modem used in Optus network ?

Wondering if you have any further suggestions of modems on ICS accessing the Optus network?
I'm currently running JVT after switching from JW4 - JW4 was good for battery but the call quality and GPS were poor. Too early for me to comment on JVT but I'm looking for suggestions of what modem to try next if this one doesn't make the grade...

[Q] SGS (2.3.3) 3G Disconnects (weak siginal)

I just i have a few SGS's and i just installed 2.3.3 on one of them and the problem is it disconnects from the wireless network when the signal gets low.
Side by side the signal levels between the the 2.2.1 and the 2.3.3 units have the same db level, but the 2.3.3 will declare the signal strength is too low and disconnect alot before the 2.2.1
Correct me if im wrong but this version of gingerbread uses the nexus s kernel right? And i've seen lots of complaints about weak 3G on those phones, and google has given up on making a fix.
Any help/insight appreciated
I know, i wave the same problem, it would be nice to know why!
Hi,
what settings do you have in settings->display->energy savings (o sth like this - I am using polish version). There is an option to save energy based on LCD, but... it saves energy probably in more than LCD areas...
When I have bought the phone - I was very confused/upset when my SGS can not use 3G nor HSPA... instead of H displays G (or sometimes E) on connection icon. I suuposed it is broken, when compared with my collegues phone (he had H icon)...
Than I found the solution - switched off energy savings, and than my phone started works well with High speed connection - chech this out...
regrads.
ps. I am using android 2.2
ok, for america its call power saving mode, i'm gonna try it to see
Edit: I try and doesn't work for me...
FIXED
I found a really good fix that has been working awesome. I went and installed a new modem kernel using clock work mod.
I get great signal (haven't lost signal yet), gps, im always connected to data.
Just go on here, download the appropriate kernel and install.
My favorites are I9000UGJL2 and I9000XXJVK. Play around, see what works best in your area.

Wireless and network signals recently very low

Hi all,
Within the past week or so, I've noticed a fairly large drop in the signal strength from both my wireless lan and 3g signals. With the cell signal, it was even dropping to edge sometimes when I was outside in an area which used to give me full bars. Wireless isn't much better, and it seems to be fluctuating between 4/5 signal and 2/5 signal even though I'm close to my router. Again, I used to have full signal in the same location. Nothing really would have changed.
Yesterday I tried flashing Continuum (2.3.4) instead of running the stock 2.2 that I had before. The 3g signal seems to be *slightly* more consistent, although I'm still not at full bars, whereas I always was before.
Is this a common occurrence? Is it my hardware, and can I fix it myself, or do I need to send it in to Rogers? I've only had the phone for about 6 months now. I wonder if it's under warranty still (assuming I flash back the original ROM and bootloader).
If anyone has any suggestions it would be much appreciated. It's odd, but the wifi signal almost gets boosted when I'm trying to use the internet, but not to full bars even when I'm near the router.
Bump. Is this the wrong place to ask this question?
Cheers
My AT&T Captivate has similar issues. Mine started about a month ago. I haven't put any effort into figuring out the root cause.
Yeah, I'd really like to figure out what's up though. Does the hardware just crap out after a few months of use? Thanks samsung!

This trend happened with my HTC Aria as well. I don't believe its anything related to Samsung hardware crapping out.
So, if it's software, what would be consistent across a ROM and kernel flash?
I recently fixed a network error effecting call quality by flashing a new modem. I know our issues are different, but since you did flash new ROM i dont think it could hurt.

Stumbled across this article on Toms Hardware today and felt like it was a good read for this thread.

Unfortunately it's not just my wifi that has issues, but 3g as well.

Have you tried flashing a different modem? The one that came with your current rom may be different than you had before which would account for your weaker signals. Different modems work better in different areas. Try something else and see if it doesn't help, such as JK4 or JL3.
I haven't yet, but I actually had the problem before I flashed the ROM.
Where are you located. I have absolutely ATROCIOUS reception in Atlanta, and ATT says they have some 50 towers down. Your area might be the same. In my basement where I used to have 3 bars consistently, i know have to run around the basement struggling to get one bar to send a text. ATT needs to get their act together or everyone might start switching to Verizon.
In Toronto, Canada. We usually have good reception. It's only recently that I have had issues.
check with other people such as your family and see if they have bad service too, if so call your service provider, there may be an issue on their end. Other than that all I can suggest would be a full reset to factory and a master clear and then restart from there. While that is annoying, it might be worth it to solve the problem.
