My wife got herself a 32GB T-Mobile Galaxy S7 last November, and she's noticed that she gets horrible for 4G reception compared to other, crappier phones in the household, even though we're all on the same carrier.
She's asked me to try to find any way of improving the number of bars she gets, everything from settings tweaks to flashing firmware, up to and including solutions that would require rooting. (Which is big for her, because she's normally opposed to rooting because she thinks it just invites stability problems and crashing.)

I have the same issue with my tmo Galaxy s7 (unlocked). I bought it as an extra phone to use on Cricket, but it is practically unusable (on Cricket using att towers). It will completely loose it's signal in a dead spot, and then refuse to reconnect when the signal returns. It's much better on tmobile (mint) but still one of the worst phones signal-wise I've experienced in years. Great phone otherwise, so would love to be able to solve this problem.

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.
Hello all.
I have a Oneplus 6 and for the past year have had reception problems. I have had AT&T for many years and my previous phone (Oneplus One) and my current (Oneplus 6) did work just fine (between 2015 and 2018). However, since mid 2019, I have had dropped calls and almost every call I make/receive from my house (located in suburbs of Chicago) the person on the other end can not hear me well (I can always hear them just fine). I have updated my phone OS with the official Oxygen versions as they were released. My thought was that AT&T changed settings on their 3G towers and were denying me the ability to make voice calls over 4G (I can see that when i make a call the icon changes to HSDPA....maybe I am missing something?
So, after countless phone calls to AT&T, I decided to try Google Fi. I have been using both sim cards in my device for a few months now. Google Fi has been good, much better than AT&T, but lately it too has been giving me similar issues.
I am posting here to see if perhaps anyone has any idea on whether or not a new rom (Lineage OS or similar) will help. I am not new to flashing roms, having used Lineage and Cyanogen for years.
1. Would a new rom help my situation? How so?
2. Is there a particularly Stable or popular rom that the Oneplus 6 community gravitates towards?
Thanks!

Funny that you mention that. I have returned to Google Fi after a year and the mobile internet quality has been worse than ever! It just does not work most of the time. Either says LTE, but with an exclamation mark or straight up does not work. I am on latest stock and also wondering if lineage would help.
It seems like putting simcard into sim slot 2 gives marginally better performance? Not sure.
When installing opengapps, you can replace stock carrier services with google's. Might help. I will try it today
Offered an unlocked note 20 ultra

issues? Eg. Hi def calling, wifi calling

Years ago I had compatibility issues with some verizon features with an unlocked phone.
Please thoughts or recent experiences would be appreciated. I currently use a verizon specific

Factory reset. I am getting great reception and
8+ hours of screen on time w/ accu battery.

Hi
Since few months, I don't receive 4G calls anymore and when I call someone in 4G, it needs 10-15 sec before to hear the tone. I need to force 3G to be able to receive calls.
I tried some others ROMS (with clean flash) and I didn't find any solution.
I also tried all the modem firmware (XNPH25R, XNPH33R, XNPH44S) but bluetooth crashed and I didn't have network.
OnePlus One

Band version : 0.1.c1.11-00006-M8974...
Do you have any idea ?
One plus One has been deemed incompatible to T-Mobile as of Oct 2020. No reason was given other than you might expect is you guys are not replacing your phone and a good phone like 1+1 is making them lose money. ATT to follow on APR 2021. You can argue your case but expect problems. Also check the type of LTE that was upgraded on the towers to LTE + which this phone does not do. I still think if the Carriers are going to make these kinds of changes causing financial stress to their customers than they need to be broken up again until downward compatibility is established or the phone manufacturers make the modem a chip that can be changed to allow the upgrade.
Greetings.
Jist bought a phone a few days before.
Noticed that 8/10 incoming calls failed, it looks like I'm out of range.
But I'm not!
I faced this on Jan update.
I've been trying all firmwares from google site and recognizes that my network works well on the first November firmware and the latest Beta 3 so I stay on Beta 3.
I realized that modem with version g5300g-220923-221028-B-9229469,g5300g-220923-221028-B-9229469 is quite bad.
But Beta 3 contains newer version g5300g-221229-230118-B-9499472,g5300g-221229-230118-B-9499472. Now my network is good, I can call, everyone can call to me.
However, a new Feb update doesn't contain new modem version, so staying on Beta 3...
Does someone experiencing similar issue?
You don't mention what carrier. Looks like with February they have a separate system image just for T-Mobile.
No carrier, I have a neverlock version.
Have this issue with Kyivstar operator (Ukraine).
Only on Pixel have such issue.
My other phones when I replace sim to them (OnePlus 7 Pro, Galaxy S22 Ultra) operating quite well.
