SM-G950F on T-Mobile: Low signal while not on a call - Samsung Galaxy S8 Questions and Answers

Hello,
I bought a new unlocked S8 (SM-G950F) to replace my dead Nexus 5x (rip) and am having a strange issue. The phone sits on 1-2 bars of signal, and I often don't receive texts and calls go right to voicemail. However, outgoing activity works, and then I see all the missed activity. If I'm on a call, I get 4 bars, no problem. Seems like some kind of idle power throttling issue.
Same behavior as described in this other thread, which unfortunately got no responses:
https://forum.xda-developers.com/galaxy-s8/help/receive-calls-txts-using-verizon-s8-t3775149
I posted to the T-Mobile support forum and someone recommended I come here and look for a combination ROM to make it fully T-Mobile compatible. Can anyone point me in the right direction on this? I've been searching, but I haven't touched ROMs since my old S3 and I'm not sure what's up anymore, or why this phone would behave this way.
Thanks for your time!

Source of connection, phone call problem.

Seems nobody talks about the call problems anymore. My guess is people given upp. Well the good news from Sweden Samsung is that they are aware of the problem! They have keept denying it or saying tbay cant replicate the problem. Finaly it seems like they are actually trying to get there hands dirty. Maybe because its on all new Samsung mobiles.
Now i was having a idea about the source of the problem, but to get some peace of mind on it, all can post if it works, or not. Hopefully we can at least get to the source of the problem.
Now here is my take on the issues, my way of counting out factors:
Here in Sweden, only 1 carrier have Edge on there network. And its the only company reporting call/connection issues. (calls get randomly muted, robot calls, phone keeps changing network, slow internet etc)
Samsung have a new codec on there phones, trying to achive a new, better, call quality. So my belives is that audio codec have trouble using Edge, and that could at least be a start to find the root of evil (but with a great original idea)
So, do you have the mute call issue? Yes/No
Do your carrier have Edge? Yes/No
Plz answer and lets see if we have a more direct approach to complain/call in issues to Samsung all around the world, remember. The more that reports/complain to the company, bigger chance they speed up time to fix it ... although Samsung isnt fast to come around :/
Well post away, does it work on Edge or not?
Yes I have this problem and my operator has EDGE. And I'm battling to get another phone in this price range (probably the HTC desire HD), becasue my service can't fix this and the operator has no clue to what could be wrong. I recomend you ditch the omnia to.
Remember to not but Samsung s2 or any, same prob.:-(. Been thinking the same as you but im gona stick to it cuz my phone is carrier free etc, and my current contract ends in 3-4 months or so, so im on to a new carrier. Sad but thru. Samsung should have addressed this issue fast, now there paying the price on other newer models.
Thnx for the reply, 1 answer and still on right track :-D
given up is the correct word...
next phone won't be samsung either way =) just to bother them!
Can you relate to edge problem to?
Seems there is no Omnia 7 uers left =(
Yes I have the mute call issue, but as far as I can tell, my Carrier does not use EDGE.
When the mute call occurs I see the phone rapidly trying to change networks, and ultimately if it settles on G there are no more mutes in that call. If it goes back to 3G it happens again. During that time the phone loses the signal completely, then jumps back to full once the switch is complete.
Darn, that could mean the end of my theory. Make sure your 100% sure.
Now, with so little going on, i thought people would love a poll to klick on =P
As far as I could find out, My carrier had a test rollout of EDGE in one city, but didn't continue with it. So, no, no EDGE atleast not in the areas I go to.
I'm in Austria, Provider is A1 and it uses EDGE
Fixed my problem by locking the phone to 3G network
Downside is that I have no signal in an area where 3G coverage is poor...
(so I've to switch back to automatic mode sometimes)...
man, this sucks really bad...
Given up describes it best, so many critical bugs (not only the call issue), never ever Samsung again, its a brick with a great screen. How come early reviews didnt report any of these flaws...
I locked the Phone to 3G and still experience silence during calls and creepy modem sounds. Phone tries to switch 3g on and off and eventually loses signal altogether. Last time I could not end the call after it went silent, windows just froze saying "ending call.....".
Usually doesnt happen in areas with really good coverage like cities, but rural areas make it unusable.
You used Cheveron? I have the call issue bug. Sometimes it happens and sometimes its like there no problem. Its like some days is a bad day and other a good day.
I know for a fact that all carriers in Sweden have no problems exept 1. And since the phone is otherwise the best, im soon changing carrier ... cant wait.
I bought my omnia about 5 months ago from ebay and I face this mute problem since, I was living in Oman when I bought this and now I am living in Indonesia and still facing the same problem even if I used another carrier SIM card.
Actually in my case this problem start only when I received a call and I start can hear the caller voice exactly after 12 seconds of connection and after that call, the mute problem happen for all incoming and outgoing call and I need to restart the phone if I want to make outgoing call without mute problem.
Are you guys having the same symtomp and situation?
fyi all carriers in oman and indonesia has both edge and 3G mode, but locking the phone to 3G didn't solve the problem in my case.
yep pretty much the same, you need to restart it in order to place a call again. That however doesnt guarantee that it wont bug again in a couple of minutes. Its very sensitive to signal strength, hence it happens very irregularly, nevertheless its not an operator issue.
Its maybe more pronounced on some networks since coverage varies.
Locking to edge definitely wont fix it, since it will bug on 3g / 3g+ switching still. It is a Samsung radio issue, its time they finally take credit for their flaws...the hard way.
Some more info from me. My theory is that this is not a Samsung-operator problem but only samsung problem. Because I have also tried my phone with a diferent SIM and i had the same problems, mute/modem calls, a little less but nonetheless. So this I think is totaly a Samsung f*** up. I you can excange your phone for a nother in the price range. The HTC sensation seems good but I know it's android but hey better android then a phone that even can't handle calls. I myself am in talks with my operator to change the Omnia for the sensation because they can not fix the problem. I also got we never heard of this before and then I recorded a video of the phone making the modem sounds (the video is on the forum) and presented it to them and said that they fix this or another phone, and now they I think will never know how to fix it so I will probably get a new phone (the sensation). Cheers.
That its Samsungs fault is there no question about. But i just wanted to se if Edge could be a problem, as it seems to be in Sweden at least. And help folks at, for now, choose a diff carrier that might work better = we are all sleeping soundly. Omnia 7 is the best phone out there atm according to me. But thiss connection/ mute call is really destroying one of the best phones atm. :'(
@voltageMX, lucky you but I think you're going to miss samoled display since Sensation only have SLCD display but at least you'll have a phone that working as a phone.
Too bad I bought my omnia from ebay...so I can't ask for replacement from the seller.
my only hope is mango update will cure the problem...
When call issue occurs i usally turns phone off, remove battery a short short while and start it up. I have noticed this have a lottery effect, i can go some day without the issue, only to se it return again, but as a temp fix it ...is better then nothing =/
Now is there any others that called Samsung in there country recently? In Sweden we got a radio Firmware you can get...by sending in your phonE!!!
But it seems to do the jobb. Internet have been reported faster also. We had users signing up and talking directly to Samsung to aid them in there search for the problem. And finally we got it. Waiting for my phone to return so ill report back about firmware version etc.
So, anybody recently talked to Samsung?
Hi,
I'm from Malaysia and I used to have the 2 seconds mute when I was on a 2G network. After that I switch to an operator which only has 3G (domestic roaming for 2G) and I don't face that issue anymore.

[Q] Help: Can't Answer First call if phone is asleep

My friend has a new stock s5 and can not answer calls if the phone is asleep(screen off)
The phone rings and the screen turns on with the answer slider.
He slides the answer call and then it just sits there for a few seconds like it is frozen, but never answers the call.
He can then call the number back and everything works fine, or if the person who called calls back while the screen is still on then he can answer just fine.
We live in a village in alaska (phone company is GCI) which only has edge data.
When he is in anchorage he can answer calls just fine even when the phone is asleep.
He has put his sim card in his old iphone and it works fine.
His wife got an S5 at the same time and both of their phones have the same exact issue.
I have no problems in the same area with my old S2 or my newer S4.
Any idea on what he can change in order to answer calls the first time?

No thoughts or ideas on this issue?
I also have this same issue. It does it when its asleep and it also does it when its awake. For some reason it just wont slide over to answer its weird. Mine doesnt do it every time it does it 3 out of 4 times though.

There have only been a very small number of reports across several phone models of this behaviour.. and AFAIK no one has elucidated a pattern that would elucidate a cause with any certainty. I can tell you that my 900T with the Phoenix ROM does not have this issue.
Unfortunately, no one who has posted with this issue has provided nearly enough details about their configuration to narrow anything down but as pure speculation it may just be a delay in waking up that effectively misses the window in which you could answer the call. If so, then debloated ROMs, faster data connections and those utilizing less power saving features i.e. typically throttling the active processor would likely see the problem less or not at all.
.
Perhaps try reducing the proximity sensor delay time. In theory that may reduce the transition time from screen saver to dialer /home screen.
Edit (or add if not present) build.prop
Code:
mot.proximity.delay=0
ro.lge.proximity.delay=25
ro.telephony.call_ring.delay=0
ring.delay=0

[Q] Note 3 not receiving phone calls.

Hello all, I've been a happy owner of a Note 3 32gb for Verizon for around 6 months now. The phone has been working great up until about 2-3 weeks ago and what its been doing in place has been quite strange. The phone REFUSES to receive phone calls, but its COMPLETELY random. Some days it will work just fine, others I will get reports from people that they called me 3-4 times, the phone rang all the way through, and I myself would never receive as much as a notification that I was even getting called. It's happening very consistently with my Girlfriend (We talk quite often, long distance relationship) and Its really beginning to get on both of our nerves. I've also had issues with text messaging, I'll receive messages from her DAYS after they have been sent (And I've already received them) and in some cases we've had texts come through that we didn't even send, at one point a text that I sent her, made it half way there, and the second half of the text was replaced with what appeared to be someone elses conversation. The phone works just fine for surfing the internet, tethering, etc, but when it comes to calls and texts it seems to be all messed up. I've tried resetting it, and I've checked my sim card, neither of which seem to be the issue. I'm currently located in Pensacola, FL, and am receiving decent service (2-3 bars most of the time on 4GLTE). Anyone have any idea what the issue could be or a way to resolve it? I was really looking forward to the Note 4, but if this is the kind of thing I can expect from Samsung I'll end up going else where with my money.

The problem can be from the mobile network or from your phone.
But it sounds most likely the problem is from the mobile network.
Put your SIM card into another phone for a few days to see if any problem.

S7 edge delayed busy signal issue

Desperate for a solution so here's my issue. Brand new S7 edge on Virgin Mobile Canada. Phone works flawlessly except when I place a call to a landline that busy. When I call a landline with no call waiting and someone is on the phone I should get a busy signal but do not. I get one tone of the busy signal then dead air for 35 seconds at which time it returns to normal. The odd part is that certain numbers this happens with 100 percent of the time while with other numbers its intermittent and still others it never happens to. Virgin had done extensive testing and troubleshooting and claim they're are no network issues. If I put my sim in other phones there are no issues and the problem disappears. Has anyone else experienced this or can anyone offer some suggestions as to why this may be happening. I really can't see it being a hardware issue given the symptoms but it sends to be pointing to it. Samsung has no record of this issue. Any and all suggestions will be appreciated.

Galaxy S10 Plus - during calls, I stop hearing the other side but they continue to hear me

Super annoying. As the subject says.
Went to T-Mobile, they replaced the older sim with a new one (newest sim version).
Still happens. Happens everywhere, through different states/cell towers, so it's nothing local to the tower. After a few seconds I get the other party back on the line, they say they heard me all the time (including the cursing).
Any idea what may be the issue?
Thank you.
Bump
Anyone??
So no one else experience this issue?
