Hello,
I have a Samsung Galaxy s3 and ever since going to 4.3 my signal strength for mobile is weak, very weak.
I have re booted phone, taken battery out, tried different modems but all with no luck.
Has anyone else had this issue and successfully fixed it?
Cheers
Got the same issue, as I flashed the new Alliance Rom on my S3 LTE. Most time I had just one of five network points.
So I did another Full Wipe, and used the Boeffla Kernel with stock modem.
Got slight better results, but there are always lil interferences while talking. Probably its the bad network by german T-Mobile.
Regards
I have the australian optus version and signal where I live is really crappy on 4.1.1 I upgraded to 4.3 the newest one from hong kong (the one my rom is based off) and now I have found that the modem and ril driver in that version is giving me stronger 3g and 4g signal

I am in Hong Kong with the following
JB 4.3 XXUEML8 rxtreme JB 4.3-V2.0
Hong kong modem ZHUCMK1
Stock kernel of XXUEML8
My house is at 35/F of a building, my phone will have signal as stated below:
LTE/WCDMA/GSM signal with 2-3 out of 4 bar
WCDMA/GSM signal normally full 4 bar
Hey everyone I am back developing again haha Noticed this myself with 4.3 so I have looked into it and noticed something very different with 4.3GSM RIL class files. They are are all reverted to the standard GSM ril type files, where as on all previous generations have used QMI based RIL.
I have created a patch that I am about to test and if I have any luck I will upload it here for you guys to try out for your selves. It should work for other countries as well so long as you have noticed a difference in the RIL types between 4.3 and 4.2 or earlier? If not then I would suggest leave things as they are and flash a new modem.
I am on Optus and I am comparing the first 4.3 release to a stock Optus Android XXALI5-OPS, does anyone know what the version number is called from the OTA update for Optus?

I have the same problem. My wife has an I9305 and I have an I9300, both with 4.3, my signal is way better and usually get H+ internet and she just gets Edge.
Any progress on the fix? I would love to have the patch, or even just the information on which files to change and what to change.
Thanks

Hello, I recently bought an unlocked and rooted galaxy s i9000 from someone. Its running Dark Knight 5.5 and Devil Kernal. I have little to no network signal, wifi works great though. It has a rogers sim card in it that works fine in other phones. I have never had a connection issue and no matter where I go with this phone I have extremely bad service ! If anyone has some ideas that would be appreciated.
Thanks
Could I just flash another modem too it , one that might give it better signal?

What baseband version are you on?
System Settings - About phone - Baseband version.
I am having signal issues also.
I get maybe 2 bars then none then none sometimes.
I am running Team ISGS ICS4.0.4
This is really unreliable now.
My phone started doing it on Rel 4.2.
I used the KG3 modem and I now get FULL bars.
Here is a list of modems:

Sorry dude, i clicked the thank-you button by mistake. Have a freebie on me.
JW4 doesn't work in Canada. Here we need 850 & 1900, therefore KG3.
Flash the kernel again
I guess its due to the kernel.Dlash the rom.See to that you clear the Dalvik Cache too:angel::angel:
Hello there, i have installed TAJB Rom and it's great. Before and after flashing rom, i did factory reset and wipe cache. I have installed this rom over cyanogenmod 9. There was no signal problem on cm9 but in jb it's very poor. I can't get a good wireless signal even if i'm close to router. And gsm signal is the same. It was 3 bars in my room before flashing. Now its only one bar. What might be the problem? Which modem should i flash? I live in Turkey
Try using the suggested modem for Jelly Bean which is KF1. I'm from the Philippines and I had no issues with the signal even if the modem is for AT&T US/Canada. Currently, I'm testing KJ1.
Just experiment.

Hi, actually i have two questions :
First: i am using a JB Leak XXLSC ( Ultimate 5.1 In particular), the rom is awseome but
when it come to mobile data connection its disappointing. When the mobile date is connected
to any gsm (2g) network the connection is stable and does not drop but when i connect to any
wcdma (3g) network the connection is awful it just keep connection for 10 20 seconds maximum
then drop for while and reconnect again and the same happens always. I changed the modem and
used XXLSC XXLRK DDLR1. Note that when using any aosp rom with DDLR1 i have perfect 3g
connection. any one faced the problem may help me with a solution ?
Second: I've noticed that all tw based roms connects to HSPAP (H+) network which have the highest
speed (20mb/s), but when using any aosp rom (cm9,cm10,aokp,cna,slimbean) the maximum speed
i get is HSDPA (12mb/s), so why is that? anyone care to explain
UP ....................
simply flash a stock ics rom if you can't live in rom with bugs it's a leak version of official jb not a official stable one my friend

I Know that, but I want to know if everyone else experiencing the same issue or is it just me?
Up again ...
I would constantly have issues with a disconnect from my network. If I lost a signal, I would have to continuously reboot to get back on. With the 4.3 upgrade, these issues are gone.
Anyone else experience this or am I the only one?

4.3 made those issues appear. Didnt have those issues in 4.2.2
On 4.3 my data is 3 to 7 times faster, but my wifi speed has been cut in half. Reception or signal cutouts have never been a problem for me on either version.
Reception for 3G was great on 4.2 but now lousy with 4.3.
I have to switch to using 2G only at home now to get any phone signal.
I may go back to 4.2 unless there is a way to put the baseband/radio version for 4.2 into 4.3?

Yes, you can flash older baseband on 4.3. I am using stock 4.3 with .48 baseband. You can get them here: http://forum.xda-developers.com/showthread.php?t=2087227
Okay have flashed back to the .48 baseband radio on 4.3 so will see what happens. Had one drop out but seems a little more stable than before.

thanks for the link. i have collected the thread for later use.
On 4.2.2 I had problems with my home wifi (but nowhere else, so I blame my config) and the 4.3 update fixed them.
Hello to everyone in this community,
I like [4.2.2] CyanogenMod 10.1 maclaw, but the times I've tried, I have the problem that has very poor reception phone signal.
In the city I can call, but as soon as I get out of it, says the network is not available.
some solution (Jazztel) (Galaxy s3 mini)

Hi,
some people reportedly have issues regarding signal strength on the radio interface (RIL) with their S3 Mini running custom ROMs. It works fine for me on a GT-I8190 and baseband I8190XXAMG4. The AMG4 should be the latest official one, according to sammobile website. Which baseband is your device on?
You could also try to flash Oliver's ROM (as I did) and see if that helps: http://forum.xda-developers.com/showthread.php?t=2384232
thanks for the reply, the case is
I tested with and AMG1 and AMG4, but with the original rom I not have any problem
I have very poor signal on any 4.2.2 ROM. Luckily I can rely in WiFi. Has anybody tried netforks?

I'm only rooted and my signal is poor. It was fine before root.
