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.

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.

Roaming can be disabled in Settings > Wireless and Network > Mobile Networks.
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

Weird issue I'm having on a G920i. In Settings -> About Device -> Status, the signal strength is being reported incorrectly. When I first boot the device, it will show accurately and will vary from -90 dBm to -100 dBm when I am at my house, which is consistent with every device I've ever owned. However, after 30-45 seconds, it will start reporting at "-113 dBm 0 asu" and it will simply stay there and will never change, even as I move about. The number of bars in the signal strength icon on the status bar will even change, but in the Status menu, signal strength simply stays at "-113 dBm 0 asu" permanently. Connectivity seems to be fine--I have no problems making calls, browsing the web, etc. The signal strength in the Status menu simply seems to revert to and stick at 113 dBm 0 asu with no explanation or other impact on the phone.
For what it's worth, I've tried both the New Zealand and Singapore AOD1 firmwares from Sammobile.com. Same problem on both. I'm on AT&T in the U.S.
Anybody else seeing anything like this?
Yes it seems both the g920i and g920f all have this problem. Every single device. Please get in contact with Samsung about it, the more people that complain the more likely it will be fixed.
@mupet0000 & @phositadc I've seen you guys in a few forums talking about the Galaxy S6 SM-G920I signal issues... Mine is the same! Swapped 2 phones already and they have awful lte reception... I was hoping a different modem/baseband would help but it looks like it doesn't....plus a few soft reboots as well what's going on? Have you guys experienced any reboots? Can this be fixed with a software update?
OK checked mine and its yes your right. -113 in status however if you type *#0011# in your dialer you'll see the better reception reported. Interestingly this did not happen when I was on the Cricket towers(At&t). I just switched to T-Mobile and I now have the -113 status. My speeds are great but I can't side-by-side compare the radios to anything to know if there is a real problem.

No reboots here. I flashed the aod3 modem last night and things seem a little better on AT&T. On the aod1 modem, I was not getting LTE in a bunch of places that I've always had LTE before. I know the g920i has frequency support for AT&T LTE bands, and I do get LTE, but I must say so far the experience has not been as good as other LTE phones I've had. Not sure if that's the modem firmware to blame or the hardware itself. Probably firmware.

Hey all, I'm in the UK and I have the SGS6 edge on the 3 network here. I use my phone for tethering at all times as I do not have wifi in the house. with my SGS5 before this I could easily run my PC , Tablet my son mobi and his gaming PC all at the same time with no issue. The S5 would run a full signal and load very quickly HD content.
My brand new S6 is disapointing singnal wise from straight out the box. I noticed my signal level fluctuating up and down but very rare dose it show a full signal level. and as for teathering I am finding it very hard to live with.
I will be suprised if Samsung sort this out with firmware. I just had a 150 MB firmware update yesterday and my signal level is the same.
I remember my Nokia N96 having this same fault, and although it was all over the internet back then, Nokia did nothing in all the firmware updates I had. I was going to sell my pristine 7 month old S5..... but I think I will hang on to it for now.
Hey guys, I am on the latest OTA released by Samsung (AOE3 built May 7th) and the problem is still not resolved. LTE signal still awful and LTE signal strength still -113. So far so bad. I have contacted Samsung again, and tomorrow I have a phone call with their support where they will remotely access my phone so I can show them the problem. I will show them and see how it goes, and I'll report back here.
I will make it clear to them that the signal strength is worse than my 2 year old S4, and I will demonstrate the incorrect signal strength value to the support agent. If they tell me it's a non issue or they make some silly excuse instead of investigating, I will simply sell the S6 and get another phone.
This is a huge issue and I'm disappointed that there aren't many people noticing this or reporting it to Samsung. The more popular the S6 gets, the more people will notice that their old phone holds a better signal.

I think it is a widespread issue... I always have 1 bar lte and under my signal status it say - 113dbm which is zero service... It never moves... I'm gonna try custom rom and see if that help but it obviously a antenna/modem baseband issue... Also someone mentioned it could be because the Galaxy S5 uses Cat 4 lte and the S6 uses Cat 6.....its very disappointing! Hopefully it gets fixed or I'll return to the S5...i really want to like this phone..... But Samsung is making it hard to
I don`t think there is anything wrong with the signal. even if I only have 1 bar the phone is perfect during calls and my LTE/4G download speed is even over the provided speed my carrier provides, I think it`s just a bug that it`s showing less signal then what it actualy has.

This is true. It's simply a bug that shows the wrong signal strength - mine shows -113 but I'll have 3 bars so that makes no sense. However, if you ARE getting a bad signal, that is a different issue altogether.
(btw I started a thread about this already several weeks back)
Spoke to Samsung on the phone, they didn't need to remote access my phone to see the issue. They had an S6 in their office and they told me they saw the signal at -113dBm just like mine. They say they have passed this onto the relevant team and hopefully it will be fixed in an OTA and I should stick to the United Kingdom BTU firmware (the correct firmware for my region).
We will see if this gets resolved. They definitely know about the problem now and have seen it with their own eyes, so I'm hopeful.

Ok.. Thanks... I already read through that thread too... Been trying to figure out if it was just me or alot of people..... Seems like the 920f is getting more updates that us.... 920I......The latest is AOD3 right? Today I'm gonna flash a custom rom for 920f and see if there is any change....
*edit* just checked Samsung live update... AOE3 was just released for 920I for TTT I guess is a country called Trinidad and Tobago... But that is the firmware I've been using.... Hopefully this will help... Let Ya guys know
*edit #2*...ok guys just updated to AOE3.... Bars still show low but the signal status is working and it's showing that I have a better signal than with *#0011*... The - dbm and asu is now extremely close to my S5... So in conclusion the signal is strong it just doesn't show it in the bars like previous Galaxy's
I am on my 3rd S6 now in 3 weeks due to rubbish reception. Im lucky to have 1 bar (-113 db) of 4g signal in my town which has full 4g coverage. If I put the sim card into my G3 or M8 I instantly get full 4g coverage (approx -80 db). Now this is clearly a widespread issue as a quick search of google brings up people all over the world on EE, Vodafone, Virgin, AT&T and sprint to name a few. Just wondering if anyone else has this issue. Im convinced its an issue that can be sorted with a software update to the modem but then who knows lol.
I got G920i model and I am using it in Canada. For me, the network is constantly fluctuating and it is stuck at -99db =\. I thought it could be hardware, but it is widespread. I am gonna get Canadian Galaxy S6 version to test this. If that has same problem, then its all S6 variants.
I hope its software because I love this international model and it has AWS (B4) that works on my carrier!
I am on latest 5.0.2 BOF6 (June 20 build). Has this network reception problem fixed in 5.1.1???
No I updated the modem first on mine to the 5.1.1 modem and it made absolutely no difference. The updated the whole rom but again no difference. Im with you in hoping it can be sorted with a software tweak to the modem. Maybe by increasing the tx power of it. But its certainly widespread so just need samsung to take note and do something about it.
Hmm...might be an antennae hardware issue. Bring back your S6 to Samsung for warranty check...
This is my 3rd one now with the same problem. The odds of 3 handsets having the same fault are pretty big. Coupled to the fact there are hundreds of people with the same problem. I know that on the old s4 and a few other phones there were apps to actually increase the tx power of the on board radio. Im convinced its just a snag that can be sorted with a software tweak.
So I recently rooted and did the Unofficial Lineage OS 16 rom on my phone. My question is if there are flashable modems to improve my cellular service due to me being on Metro PCS and getting spotty service at my job and certain places around where I live. I do understand that I live in the country and I won't get perfect signal service but I am wondering if there is a way to make it better. This is a GSM phone. If anyone has any tricks or something I can do to make it better let me know. I have done different stuff in the past to other phones(QPST) and plenty of flashing(I used to flash CDMA based phones to cricket long ago.) I know what can fully brick a phone too. Anything helpful would be appreciated.
