[Q] poor signal strength on Galaxy S

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

[Q] Experts needed. Since 2.3.3, Wifi signal tend to be low.

Can someone give me a good answer about what happened to WiFi signal in 2.3.3
I used to have maximal WiFi signal when working with 2.2.1
After installing Darky's v10.1 - 2.3.3 ROM, WiFi signal tend to be low (1-2 bar only)
Other laptops / phones (not android) report maximal signal of WiFi.
I tried almost all possible modems - I almost sure it's not related to Modem.
Can someone provide a good answer what happened ?
Is it a report problem only ? Is it a ROM issue ?
(I cannot find a good answer anywhere)

[FIX] fix static noise / bad call quality

tl;dr:
A SU660 BB (824, 1120, 0420) will fix the weird static noise and bad call quality issue on "made in Korea" devices!
You'll find more information on this issue in this post and more information (including known issues and fixes) on BB 824/1120/0420 in the second one.
Original Post:
-------------------
I just want to share this with all of you who might have missed it within the CM7 Nightlies and Baseband discussion threads - and want to gather all information about this into one thread.
This was found out originally by vadonka here.
I found many others who confirmed that people on the other end of your call complain about static noise (like the noise when you're holding 2 phones together or standing next to a speaker).
We were not able to track down why some p990 users suffered from it and others don't. Some could fix it with the 502BB - some with 725BB and the Gingerbread leaked ROM - but not with CM7.
It appears that there are different (hardware?) versions out there.
If your device is "Made in Korea" (you'll find that info on a sticker under your battery) you might suffer from this noise issue - but not all Korea-made devices do.
For "Made in Korea" ones this noise is almost gone with SU660 BB and a matching RIL (824, 1120, 0420)!
These basebands are for the SU660 (the korean version of the P990), but work for us, too.
I'd almost given up on this issue - was using the leaked ROM (which sucks if you wanna use CM7) and intended to sell it soon. I tried nearly every possible combination of BB/RILs with CM7 some time ago - and never got rid of this problem. My poor girlfriend had to answer maaaaaaany test calls hehe.
This weekend I thought to give CM7 one more try, lurked into the CM7 nightly thread and found this Baseband which seems to fix my issue.
It's confirmed to work for the "Made in Korea" 2x's of vadonka, Sckank, TrymHansen, pastime1971 and temasek.
You'll find more infos on known issues in the 2nd thread.
So - why are Basebands which are made for the SU660 working best with our "Made in Korea" P990's? This could explain many of the "hard to track down" issues some people have - because their phones differ even if it's the same model.
You can get 824/1120/0420 BB and RIL here: P990 Complete Baseband Overview Thread
There you'll find BB and RIL install instructions, too.

positive comments
pretty similar to 725BB - if you don't have problems with 725 BB stick to it, as it might have less issues!
good call quality on both ends
good battery life (neither better nor worse than e.g. 218 or 725 BB)
good network speed & connectivity
no wifi problems
known issues with SU660 BBs (824, 1120, 0420)
automatic time is not working

Fix:
There is a fix from pastime1971 if you're using CM7, you need a CM version with the following fix cherry picked though: "Change Iaaf7f1c4: LGEStarRIL: Apply DST regardless of Infineon fix (PATCH #3)"
In temasek's or owains KANGs this fix is already included.
Head to their threads to download a ROM and get instructions how to enable automatic time.

- Installing Toggle 2G/3G will fix this with the "Turn on 3G manually" setting! (confirmed by rugglez, thx!)
- Set 2G manually (duh!)
When you're on 2G and you'll disable data and reenable it, data might not turn on for some users

This can happen with other basebands as well, it seems to be a BB/ROM combination issue
Fixes:
- activate and deactivate airplane mode
- use 3G

Fixes:
Well your phone isn't compatible to 824BB - you should install 725 or 218 instead.
As it's not compatible you shouldn't suffer from the "Made in Korea"-Noise issue anyway.

So this is the dial-up-esque noise that pre-warns of any impending text messages/phone calls?

plz tonydl i wana try 824 BB and RIL , i'm on cm7 7.2 the latest kang , but can you tell how to change it ?? (a mini guide plz)

No - it's a quite disturbing noise on the other end which won't stop. If you're not suffering (better: the people whom you're calling) I wouldn't advise this baseband.

Sure - just follow Pauls guide to change the baseband here.
For getting the matching RIL I use sibbors "GetRIL" app: https://market.android.com/details?id=com.sibbor.getril

i flashed 824 yesterday and i have a couple of problems with it.
every reboot i have to set 2G only again, seems to reset/ignore the GSM only option and the timezone is 1hour behind...
so far i have not noticed any noise like i had with 725 but havent used it a lot so i will continue to listen and ask if its better than before

Yep, it's not perfect. As I said before, you need to disable automatic time for the moment - which is probably due to the "fix" I mentioned above.
I can confirm that 2G makes some trouble - maybe Toggle 2G/3G will help you?

well it no serious problem once its set manually and since i never use 3g i just have to think about enabling the 2g option when i reboot. maybe i could try if green power can handle the 2g only option... lets see
edit: nope doesnt look like it since green power works with the device settings which are messed up. however, as far as i experienced it might be a problem with cm7, i think i have some strange behavior with every bb except 208 if i remember correctly.

Beware of imei getting hosed when you install Korean baseband. There is a way to recover and keep it handy. I used putty on windows to fix it when I messed up a while ago.

This also explains why I my phone keeps rebooting and showing BSODS when installing Spica's HP kernel. I always thought that it was strange that there where different versions of the phone.
FYI, I tried different BB and also the 824 with MIUI but the battery drain was awful. LG just released V20M for the Netherlands so i got stuck with the 725 BB.
I don't complain about the quality and I didn't try the 824 with this version. Maybe later when i'm sick of this one .

I have a "made in korea" device with 725 BB (from v20c I think) and 218 RIL. My rom is CM7 204. I have asked a lot of my friends and family and no complains for the quality.

That's interesting.
Then there're even some more differences than "made in korea".
LG has somehow managed to fix the static sound for their v20x builds with 725 BB, but CM7 hasn't.
Does anyone have an idea how to track this down to help the devs to build a workaround? I am pretty happy with 824 BB right now, but I would prefer to have a choice.

I have a P990 assembled in Korea and it had awful call quality with every BaseBand except 0502 and 0824.

i have tried 502 and it was also pretty good but the battery drain was a lot higher:O
so im back to 824. anyone know if there is a fix for the automatic time beeing off by an hour? i remember that this was present in earlier nigjtlies and got fixed somehow, so maybe the same fix can be used on this case.

Head over to this post for a KANG which included it and gives a description: http://forum.xda-developers.com/showpost.php?p=20595849&postcount=12065

This is the latest KANG build P204-16
http://forum.xda-developers.com/showpost.php?p=20610135&postcount=12098

Another small issue: the call initiation is a bit longer - if I'm too quick with saying "hello" then the other end won't get it (and vice versa).
Can anyone confirm?

hmm now that you mention this i remember that i was talking over the headset with a friend and when i unplugged it he couldnt hear me anymore. i had to enable the speaker so he couos hear me again, after switching it off again everything was fine.
its like the mic didnt switch from headset to phone when i unplugged it:/

I cannot reproduce that. Which ROM are you using and which BB/RIL?

Hello!
Mine is also made in Korea.
I tested 0622, 0725 and 0823 - 0824 didn't work.
Voice quality was always acceptable didn't notice any problems there.
But overall signal reception(especially indoors) is by far better using 0823 - but this might be a special because my provider is known for bad reception indoors…

Best MODEM for I8190N for Europe (France)

Hello,

http://forum.xda-developers.com/showthread.php?t=2526831
So i have succefully install "GT-I8190NXXANI1_modem.bin_update.zip - 4.92 MB"
But after multiple test of calls & internet connexions, i have same issue for calls and after update, i can't connect to 2G/3G so i would like to know who (in France) have test multiple modems (or have a very good modem without update it)..
Thanks for futur responses

I use GT-I8190N_modem.bin-NXXANF2-update.zip cause i had similar problems like you, with ANF2 those problems are gone for me.

Question weak wifi signals

I am using redmi 9t version MIUI Global 12.0.17 from two weeks, no update is available in pakistan.
Its wifi signal is very weak (Overall speed of internet near the wifi router is completely fine)
It sometime lost its connectivity during weak signals.
Should I wait for the new update by which Its signal strength may be better or may I sell it out in market because of its hardware issue ?
Your kind response will be highly appreciated.
thanks

First of all, do internet reset. If not help, try hard reset. And make sure that other device is fine in connecting to wifi.

some people are saying it is hardware issue whereas others are saying before april update it wsas fine and then due to bad update it is doing problem,
I am requesting you to please investigate and let me know the actual facts.

Right now I'm using the unofficial OS, which isn't miui, and all fine here. Stable, full signal strenght, I don't have any problems like you. Maybe try to co fact with Xiaomk repair center or something.

Hi, I have this problem too, the Wi-Fi signal is weak and not stable. I also used a custom ROM and it does not matter

It looks like there is a hardware issue in it .

I'm on 12.5.5.0 EU rom (last stable miui 12) and the wifi is unstable. It goes up and down and switching to mobile data.
I have tried ALL android (network/wifi global) settings but it doesn't help. Don't hope it is a hardware issue (wifi chip problem). Tried wifi data reset, bluetooth on/off, Wifi Access point on/off,.....
The only time it stays on wifi is when mobile data is turned off. If you turn on Extended wifi log in Development Settings you willl see the RSSI and Wifi Score (0-60) for your Wifi connection. But it varies all the time.
Hard one to crack.
