I rooted my Sprint Galaxy S3 to CM recently I update to 10.1.1, I noticed that my Signal has dropped dramatically many say because CM can't get the PRL needed because has something special (something I didn't understand) Is it possible for me to do anything to raise my signal strength? p]or would I have to flash stock rom and if I have to can i flash stock rom without losing my root?
CM or AOSP roms for that matter read a truer signal strength. TW roms have a different reading of signal strength. You can almost say they round up. You may still have the exact same signal it's just the reading and reporting which is different.

i had low signal from day one but occasionally had perfect 4g lighting speed
my question is can flashing a rom make me loose signal ....after flashing an updated rom today i had almost no signal at all ...
called verizon and they went through what they needed to do and said they are going to send a new sim card ....if that doesn't work they are going to do a factory restore....
anyone have any clue ?
....do... what...huh... does not...compute?
bow chicka wow wow.
Have you tested the signal with other phones? Like say for instance did a friend who with Verizon have better signal in the same room? I know these galaxy nexuses don't have the best signal, but it isn't THAT bad.
Most roms I've seen come devoid of radios, check the dev section and try out a few different radios.
IMO if the radio packages and new simcard don't work flash back to 100% stock and unroot, then send it in on warranty.

Yes we did test the phones , my buddy has the same phone and was on 4g while I had 1x...both phones running liquid smooth 1.25 ...for some reason when I ran the older version I believe it was just 1.2 I had way better signal ...
so... It seems that at my workplace, and which is worse, exactly at my booth, I started to lose signal very easy... it's as if the phone kind of detects that signal is is weak and feels lazy to be decoding that and just stops, it's like it gives up easier.
It used to work fine, always had decent signal and no problems at all.
So, I was wondering if flashing Basebands could help on this.
Also I am not quite sure this if this issue started happening on a new ROM I flashed, I honestly don't know. You think it could be related to a ROM, considering I am on stock kernel (locked bootloader)?
IMHO, it is more of ROM problem. Flashing baseband does not affect the signal strength significantly. Check with ROM dev if there is problem with signal strength.

You could try different basebands, the higher number doesn't necessarily mean you'll get better signal
However make sure you flash libs
Libs?... what libs?
I noticed a significant difference in signal strength and resilience on TouchWiz roms as compared to AOSP roms. I've tried this on a number of radios (LJ7, LG8, LI3, LIH) and gotten the same results. I assume it's just perceived as I can't think of a reason why the rom would influence signal strength. Nonetheless, when I'm on TouchWiz I can walk all around my house and get ~-70 to -80dBm. On AOSP roms, if I leave it in a particular corner of my house I can get ~ -70dBm, but as soon as I leave that corner it shoots to -90+dBm (and subsequently boots me from LTE). Is there a reason that this could happen? Does it have something to do with the data handoff in TouchWiz vs. AOSP? Also, one thing to note is that on CM10 and 10.1, my Mobile Network Type is LTE:13 and on TW roms it's LTE:14. From what I understand, there's no real difference in LTE13/14 right? Has anyone else experienced this?
Interesting you mention this. I just posted a thread on a similar problem. See if this is your issue.

I've also noticed this. On tw I can only get 3g when I'm at work in certain areas but when I'm on aosp I usually get lte although its only 2 to 4mbps its way better than the 1mbps I would normally receive on 3g
Please post questions in Q&A

Yes, this seems to be the exact thing I experience when on an AOSP rom. Anyone know what could cause TW roms to have a more resilient signal?

Samsung lies. Its in the cod to add another -20db

This is actually what I was wondering. I wasn't sure if the dBm you see under About Phone > Status was raw data or processed data. Is there any evidence to suggest Samsung perhaps averages out dBm over time, so that it doesn't fluctuate as wildly as it would in a AOSP rom?
I'm not sure, possibly a root tool would be able to accomplish this. I have a widget that says my signal. However I'm on aosp. Not sure. I can get a link one sec

I have my Galaxy S3 and my coworker has an HTC Evo. Both of us have Sprint and yet his phone gets 3 bars of reception whereas mine only gets 1, 2 if I'm very, very lucky.
AFAIK, he's running stock, unrooted and I'm running rooted with latest LiquidSmooth 2.9 with the MD4 modem. No idea what modem he has.
What could be the reason why he's getting better reception? Better antenna build in the Evo?

Some of it has to do with the rom. Some aosp roms show a more accurate bar reading...which is why your's is fewer. I wouldn't really get to worked up over it. They both probably get similar reception and data speeds on 3g

Actually, my data is absolute sh!te and it's a pain to load nearly anything. I get data transfer speeds in the very low kbps.

I'm going to agree Ivpre. I would not get worked up over it. Unless of course it is necessary for you to have more Bars showing then him :silly: . You do most likely get the same Data Speeds.

I would suggest Updating PRL / Profile. Maybe even trying a different Modem. Not everyone gets great reception on MD4. You may have to experiment to see which works better for you.
If you want to properly know if your device is getting less of a signal you need to flash a TW rom, preferably one which is close to stock update prl and profile. Then check your signal and data speeds compared to your friends. AOSP roms remember are built from leaks, and ported from other devices. There is no true aosp source for the Sprint S3. So there's lots of patches and coding which goes into getting the cdma radios working.

We've actually done a Speedtest together and his had a higher data rate than mine. I've had different modem with the earlier builds of Liquid Smooth as well, but still low reception. I've also updated my PRL/Profile in the past in hopes that it'll help but sadly no.
I'll look into having a TouchWiz ROM versus this one. I just love how LiquidSmooth is, so hoping I can find a TW ROM that's just as fun.
EDIT: I don't even know how to find a TouchWiz ROM. I figured it would say "TW" along the subject line, the same way AOSP does, but alas I cannot find that. I have heard of Goodness, is that a TW ROM?

Some devices just get better reception than others. Better internal antennae.
My mom's old photon always got better reception than my 3d & s3

Most likely cause all the roms which do not say AOSP or CM or AOKP or something like that are TW roms. I would recommend MOAR or TPR The People's Rom.

OP,
Unless you're being very careful with your comparisons and using quantitative, and not qualitative, data like db, seeing more "signal bars" means nothing.
Sent from my buttered S3
You must also keep in mind, that even after you switch to a TW Rom. There is no guarantee that you will see better reception. IE more bars. There are quite a few variables involved. What you should concentrate on is making your device the best it can be for you. As CNexus stated. When comparing you have to compare Apples to Apples, and Oranges to Oranges.

Hi All
I'm running CM10.3 with no issues apart from my signal strength doesn't seem to as good as the stock firmware. Is there any modem flashing i can do to sort out the issue please?
Cm 10.3? 4.4 released already
I have no experience of the stock rom as I installed CM immediately after buying the phone. However, I also experience poor signal strength. My signal strength is most often at 1 or 2 bars while I had full reception most of the time with my old Motorola Defy (with CM). Stand by battery capacity is significantly worse than my old phone with a 3 year old, much smaller battery.
I'm using 20130908 nightly and I9195XXUAMH1 (lastest) baseband. I'm going to get the latest nightly and experiment a little with older baseband versions and see if it gets better. Might also try the stock rom for comparision.
