[Q] How do I choose the best modem? - Verizon Samsung Galaxy S III

My i535 is on a rooted, unlocked stock, 4.1.2, baseband I535VRBMB1, with TWRP 2.5.0.0. My primary concern with the phone is it's spotty reception. I have thought that newer basebands would be the better ones, but from reading here I gather that is not always true. Can someone point me to some information that would help me choose and install various modems to see if there is one that will do less signal searching. Right now I have disabled LTE on my phone and that seems to work better. Maybe that's as good as I can expect.

FYI there isn't any modem that is better then the other as it all depends on your cell coverage where you live and how your phone responds to the modem.

Thanks, I guess that Verizon has to build modems that work for the "average" situation. If everyone lived in the same coverage area there would be a lot fewer complaints about dropped calls and poor connection. I know that it will take a few days for a modem to learn how to connect in an area. It's not fun to be stuck with a phone that people tell me is breaking up when I call them. I came from a Droid X and I'd say it had a lot less problems with calls. I have always used antenna signal amps in my vehicle and that does help. (Wilson Electronics).

The verizon gs3 has signal issues. Im in a very well covered LTE area and have issues with signal. Doesn't matter the modem. Its the phone itself.

See that proves my point that you get varying results depending on location and phone. While you got problems in a well covered area of Colorado, I get problems I certain bulidings in NYC that I had no issues with my previous phone.

I get fantastic coverage (but unfortunately not on AOSP) and I'm on a rather old modem. I figured not to mess with it because I know they're really touchy

Signal Roaming?

I have a rooted Tmobile phone (Octane) and loving it. This isn't a 'root' question, but a signal issue that I noticed before and after the root (not related to rooting).
Anyhow, when I leave an area (in my vehicle) that has low Tmobile signal, it switches to ATT and says "no service". That's fine, but what I noticed is when I return to the same area, it will take an additional 4-5 miles of driving into a strong Tmobile signal area before it pick up the Tmobile signal.
In my area, there are no agreements to roam on ATT's network, so my phone is dead until I re-enter Tmobile signal area.
My question is, it is a nuisance that my phone can't use Tmobile towers as a priority. It seems to hold onto ATT's towers longer than it should. What can I do to fix this issue if possible?
Thanks in advance!
Edit: My wife has the same phone and it does the same thing.
Have you changed modems? That seems to fix many issues pwople have with connection issues.
Not sure to be honest. I used this process to install Octane's ROM:

I did see something in Odin about "Modem" but don't know if that is the proper way to install a modem or not.
This thread will tell you how to change the modem.
http://forum.xda-developers.com/showthread.php?t=1192436
FB also recommends one in that thread iirc. But other members have better luck with different ones. Im told it depends on your location but nobody has said which modem is better in what part of the country.
Awsome, thanks for the leg work on finding that for me! Is there a way where I could opt out of roaming so my phone uses Tmobile as a priority 'all' the time?
This is just incase the modem doesn't seem to help. Just one idea I had.
Also, KJ6 modem is the one I need correct?
Not sure of the roaming opt out.
FB puts the KG4 modem is his personal build of VB. Im using KG4. I would try all of the GB modems to see the results.

Radio advice/help needed!

So I recently got an Inspire, coming from a Vibrant. I have T-mobile service. On the Vibrant, in the same location, I had superb cell signal. On this Infuse, it's more than terrible.
I know it's designed to be an ATT phone, and the internal hardware won't pick up certain T-Mobile bands, but I have also had a couple other unlocked phones that got better signal than this.
I can literally set the Vibrant down on the table with 3-4 bars of service, and the Infuse next to it with Emergency Only or an X (no signal). In other random spots I can get a couple bars, but very spotty. Sometimes I'll have a couple of bars, and literally not move an inch and lose signal. That's frustrating!
I know I can't get 3g-4g speeds. Not an issue with me, I use wireless, but I do want to figure out how to make and receive phone calls.
I unlocked using Ace, and let it run for a few days before making any other changes. Today I flashed Android Revolution HD 6.3.3, and then flashed the recommended radio about an hour later. (used the fastboot method described in the radio's readme, the RIL was included in the Rom)
So my signal is slightly better, but only barely. Still very unreliable.
I guess my hope is, to gain some insight as to how the radio even works, so I can start to learn the differences in them, and find one that works better.
Is there any hope that I will find one that is suitable?
Can anyone recommend radios/a solution?
I also wonder, since the Desire has compatible radios, and they are used in Europe, if they may pick up T-Mobile USA signals better.
Thanks for reading, and thanks in advance for your help and advice!
P.S. I know its been discussed before, however, I've read hours and hours worth of posts, and in the end I decided asking was definitely worth it. Ya'll are smart!

Radios react differently for everyone cause they are actually based on regions as to where your at. But there are positive responses on the .03 , .28 and .30 radios. Give them a shot and try them out each for about a few days and see how they work for you. Development section has a radio thread you can get them from.
Just remember flash radios at your own risk, they are a little riskier than flashing roms. Good luck

ROMS & Radios?

AT&T customer, midwest United States here. I live in a fringe area, but have always been able to get reception.... until I rooted and started running custom ROMS. It seems some ROMS, for whatever reason, get better radio reception than others.
I tried Viper, and while it was the best for reception, there were a lot of things that gave me trouble and I couldnt live with.
The CM ROMS wont even think about getting reception for me, unless the mobile data is turned on, and then are very erratic. I leave the data turned off when at home due to it always looking and searching and killing my battery. Well, that, and I always use wifi at home. I even tried the newer 3.18 AT&T radio, but it didnt help
Any suggestions as to a ROM that is known for reception? Or a specific AT&T Radio that is better for reception? While I knew different ROMS had different good/bad points... I didnt know the reception was on of those things.
Thanks

There sure is a big difference for some reason, with me anyway. The only 2 radios I have found in the Radio thread for AT&T without the RIL (senseless ROMS) is the 2.20 and 3.18 radios. I have bounced back and forth between them, and not seen any difference to speak of. The 3.18 seems to be the more erratic of the 2, for me anyway

My advice would be to try a different radio until you get one that works for you. I work out of state so I have to change settings to wcdma only to make them work in the area. I use the 3.18 radios on both CM and Sense because they work best in my home area. Viper is based on 3.17.661.2 so AT&T 2.20 may be the best option to try.
I use 2.41 seems 80% of the others I've tried plain suck in my area

When flashing radios for CM, also be sure that you are flashing the ones designated strictly for CM as the radio fw is kept in another partition than sense. I've never had an issue finding a radio that works for me. They don't all work well but at least 1 always does. When looking for the best radio, I download them all, test them one at a time, marking the signal strength and speedtest results for each and then flash back to the radio that gave me the best results.

Im getting the radios out of the radio thread here on XDA. I am d/l the radios in the lower section, for CM. I didnt try a different radio when using Viper, because it was useless seeing as I had so many other issues. I wasnt aware I could use Vodaphone or Telstra radios, on AT&T. I had only tried the 2 AT&T radios. My bad, I will try the others.thanks for the info guys. The speed tests are a moot point for me. As I said, i am in a fringe area. I cant judge anything based on data speed, and leave data turned off most of the time. Im not worried about data speed, or trying to fix anything in that area. Im trying to get my phone to get good enough reception to make/receive calls dependably and send/receive texts dependably. Sorry if there was some confusion over this.
Honestly, I would have stuck with Viper, but my wifi wouldnt work, and I couldnt even get my contacts and calendar imported from my Google account. In fact, there wasnt even a Sync option for contacts. So that was a no go.
Thanks again

Ok, I tried just about every radio in my CM ROM, to no avail. Then, on a whim, I ticked "2G Networks Only", and now I have decent phone signal/reception. This sucks though.... to have my data connection have such an affect on my voice signal. I had always left my data turned off when at home, due to being in a fringe area, and it always bouncing around and killing my battery. That, and I always use wifi at home. Now, I have to leave my data turned on, and in 2G mode... just to be able to make a call. Rather silly to me.
Thanks to everyone who offered to help... MUCH appreciated
P.S. when it was said and done, I think I wound up back on the stock radio for Cory's CM ROM (2.20?)

signal remains the same... around -87/13, but the Edge "E" icon, disappears from the screen. So, no real difference that I can tell.
It just amazes me that my data connection/type/settings can ruin my voice reception. Hopefully, its going to work decently now.

thank you! so far, so good! As long as I leave the phone in 2G only, my signal is great. Well, great for my area anyway lol.
With VoLTE being so far out yet, and AT&T not having true 4G, and voice/data being on 2 different frequencies.... how in the world is this happening on this phone? How can enabling/disabling data/4G/2G have such an affect on the voice/text signal? I just cant wrap my mind around this

I'm no expert by any means but if I were to take a guess, I would say it may be due to limitations of towers that are closer to you? IE: closer towers provide 2G signal but have not been updated to support 4G? and the towers that support 4G are further from you?
Like I said, I'm no expert, I'm merely taking an educated guess based on what I do know about the technology.

Actually, I dont know either, but that does make sense. If the phone is in 4G mode, then ti will try to connect to a 4G tower, which could be further away. But, there were times I had a great signal with 4G enabled, but it was in H, or H+.... and wouldnt make a call.
Im just happy I found how to get a decent... steady signal. I love the HOX, and I love the CM ROM... but I was ready to pull my hair out with this lol.
Thanks for the input, I may ask someone at the local store next time Im in. There is one kid in there, that is pretty knowledgeable. I think the rest of them know less than I do lol
Well, I spoke too soon. Now I have good reception, but the quality of my connection SUCKS! I have flashed and tried every radio for CM, and while I have a good signal now (around -85/13) my call quality is terrible and are all fuzzy and fade in and out.
I dunno, Im thinking seriously about going back to stock. I love the idea of having control over my own phone, but Im not in this as a hobby. I just want things to work right. Every ROM I have tried has had one issue or another.... wifi connection issues, wifi going to sleep when it shoudlnt, bluetooth connection problems, a dozen apps starting by themselves, radio/reception issues. Its to the point its just not worth it to me. I dont like having to work on anything every day, and if I do, I feel something needs to change in the situation, if that is the case. Dont get me wrong, Im not slamming any developers, or their projects.
When I was younger, I was always the first to get one of the Celeron CPU's and OC the snot out of it. As I got older, I thought... why? Ill just spend and extra $20 and buy the faster CPU so it is more stable, and not have to mess with anything. Thats sort of how I feel now

Interesting findings on the newest OTA (MD3)

I read about all of the issues people are having with the newest OTA (MD3). I decided to give it a try anyway, because I love writing emails to Verizon pointing out their flaws.
I followed the instructions in this thread: http://forum.xda-developers.com/showthread.php?t=1762709 to go back to stock, using the Official VRALG1 4.0.4 Firmware. I wiped the Data and Cache partitions after installing. After this, I applied each patch in succession BEFORE installing any other software or programs. When I was done, I immediately disabled the Caller Name ID app. I have NONE of the reported bugs:
* Texts send immediately on the first try
* Battery life is no different than it was on the last firmware
* Phone switches easily between Wifi, 3G, and 4G LTE
* 4G LTE speeds are normal
I am no stranger to unlocking, flashing ROMS and Radios, etc, but I am most certainly NOT a dev. I'm posting this information here so that someone with more knowledge than I may be able to glean some information useful to those that ARE having a problem from this post.
I was having issues with the ota and I went back to the oldest update then took the otas.
Then rerooted mb1 and flashed bonestock 2.0 with the mb3 radio/modem....still had signal issues. And that rom has all bloat removed. So I flashed the mb1 radio/modem and now I get better signal.
Ha thats my story.....definitely a mess up from Big Red.

I wiped and then installed the stock deodexed MD3 ROM and firmware and had data issues...low signal, frequent drops to 3g or 1x, etc. Ran it for a few days and it was noticeable wherever I went. Restored my CleanROM nandroid and flashed the MB1 firmware and my signal has been much more consistent again.
I was weary of the rumored issues so I completely wiped my internal storage for a fresh install, and MD3 has been nothing short of amazing for my phone. If anything the only knock on it is that the signal has degraded about a bar in areas where I'd normally have full bars. Data connectivity is fine, data speeds are fine, the kernel with this update deep sleeps better than most that I've flashed in the past month. It's been nothing but good so far

For a device that already had bad radios for low signal areas, the reception issue is bad. It is not like going from great radios to good radios, but going from barely okay radios overall to worse. Everything is relative and the radio changes absolutely suck in that regard.

I"d say this thread is now dead since Samsung / Verizon have now pulled the OTA and will release a fixed version later, That usually means 1 day for Samsung to fix it, and 3 months for Verizon to test and approve the release.
In comparing the S3 to two other Verizon Motorola phones in my family, I find the S3 signal to be as good or better to the Motos when running the current stock software, (not the broken MD3 OTA) . SO I'd say its pretty good as Verizon goes. Interestingly, I find that the Verizon S3 is not nearly as good in signal as my wife's Sprint S3 , Surprising because VErizon and Sprint often share cell towers.

This is exactly the thing. After using MB3 update a whole week, giving it a chance....my phone would still WORK in areas with strong signal, but everywhere else it went from ok to UN-usable!
There is a clear issue here but if you are in areas with only great signal you may not notice as much but it's there.

What they should do is release here first. There are no better beta testers then XDA members and we could probably find every flaw within a day, and heck our devs can probably fix most of them for Samsung anyway.

[Q] Signal drop/No service

Just wondering if any one else gets this, sometimes my signal just drops out and I get no service.
Then it comes back it does not happen all the time, I live in a big city Leeds infact so signal is quite strong.
Just wondering if it could be a fault with the phone?
Thanks

It is definitely possible.
I'm on AT&T and have the correct APN settings and have called AT&T with my IMEI. I have significantly worse signal than with my HTC One X. I am not comparing bars to bars, but rather where the signal drops completely. In places where I had low signal but still connected I now have nothing.

T-Mobile on stock ROM i had my first signal drops.
I was fine (or at least never noticed them) from the time i got my phone (day one) without any drops here in orlando.
Drove over to Tampa/Venice Beach area this past weekend and noticed some drops. Had about 6 drops according to my battery stats in 2 days. i had good to excellent coverage the entire time except when it would drop comlpetely (outline of signal bars)
would connect in a couple seconds, but i noticed over night, it would drop for a pretty large amount of time (like 10-15 minutes at a time.)
Mmm defo seems like were all having the same issues, wonder what it could be

I had this issue too, and here's how I fixed it:
By default LTE is enabled, meaning the phone will periodically scan for a LTE network. If you're in a big city, you're likely to find one. Your phone will attempt to connect. However, it fails, meaning it will have to rescan the HSPA bands to connect back. That results in a few seconds of no service. Why can't it connect to LTE? Because by default, the APN is not the LTE APN, for Rogers at least. I'd assume AT&T would be the same. You can test this by dialing *#*#4636#*#*, selecting phone info, and selecting LTE only. You'll see that there is no service. I tested this in an area I knew had great LTE coverage, and that led me to the conclusion that it's LTE causing the signal drops.
So how to fix? Simple, just change your APN to the LTE APN for your carried. To do that go to Settings -> More -> Mobile Networks -> Access Point Names. If you're experiencing this issue on Rogers, change the APN field to ltemobile.apn. If you're on another carrier, you'll have to search for their LTE APN configuration.
After doing this your phone should start connecting to LTE again, and you won't get those annoying signal drops.

A few days ago I let you know that we'd be reaching out on email to some of you for some additional bug report data. I'd like to thank everyone who responded to our email -- the bug data you sent in has been helpful to us in tracking this down.
This is looking like a software issue on our side, and we're investigating a fix.

So yeah the next update will probably fix the issue. It's not so bad in the meantime, Lightflow sill notify you that your nexus has lost signal, and you still get the internet and incoming calls.
We're not alone. Supposedly Google is "aware" of the issue.
i've hcanged my setting from '4g' to '3g' to see if i notice a difference (hopefully will) then when 4g is released or i get a 4g sim, can move it back up
Yes, I'm having issues too. The real problem is the fact that I have a Wilson cell booster in my home (supposed to have up to 5000 square foot range) and my n4 had full bars most everywhere inside. With my n5 It shows 1 to 2 bars if I'm lucky and quite often drops to none! The only way to get full bars Is to stand right under the indoor antenna. Not impressed, and I sure hope this is fixable!

I hate to revive a dead thread, but I was wondering if people were still having problems. Once or twice during the day that I can see I will lose signal for a few seconds only to have it reconnect. Running 4.4.2 so the latest update did nothing to help the problem as far as I can see and I have messed with my APN settings. On AT&T. The Google thread seems to have a lot of different problems on the same thread, and it is a bit unclear if people are still having this problem. This is very annoying for such an otherwise spectacular phone. Thanks and sorry again for reviving the thread... :fingers-crossed:

Actually, there have been several threads on the issues associated with this (emergency calls only, missed calls, no signal,etc.). Ongoing and unresolved for some.

Appreciate the speedy reply. Hope Google gets on this fast. I also have LTE connection issues which has plagued both this and my original device so I am pretty sure its a radio issue. The phone loves to stay on HSPA+ even when there is a decent LTE connection: it's last in the pack to connect to LTE and first to disconnect when compared to others on AT&T.

My N4 with a combo radio sticks to LTE a tad better than my N5 with stock radio. Sadly, morrislee hasn't fiddled and combo'd N5 radios, and I'm not sure they've been tested and sussed out like the N4 radios. Citing the fact some with issues have flashed all the radios so far with minimal success means we wait for Qualcomm, after Google kicks them in the you know where.
