The new S9 replacement phone I got 2 days ago has the SAME problem as the first S9. From the very first call! During telephone conversations, the sound goes dead quiet on one or the other side for 4 to 6 seconds then comes back so that I miss part of the conversation. In a 3 minute call it generally happens at least twice. This happens when I am on speaker, headphones AND the car phone.
[Samsung Galaxy S9+ Questions & Answers] docker_rob:
It's only been 24 hours since tha patch was installed and I havent 100% confidence yet but so far so good and no drop outs for me.

A 60 minute phone call last night and didnt have any issue with the dreaded 5 to 10 seconds of silence.
[Samsung Galaxy S9+ Questions & Answers] Dark5tar:
Based on those who have replaced their phones and still have the same problem, it looks like the problem is not isolated to just the "early release units", and can either be a software or hardware fault at this point.

For those who have installed the new "improved call stability" update XU1ARCC on their phones, please keep us updated with this stupid dropped calls problem.

I'm hoping it's just a software bug and gets fixed with this update. Still waiting for it to drop in my region (NZ).
[Samsung Galaxy S9+ Questions & Answers] dinysam:
Replacement S9 in Perth, Australia which had the same problem on Version G960FXXU1ARB1 has now been upgraded to new Version G960FXXU1ARCC.

First two calls had no silent patches :) but

still too early to be certain... will continue to test while on the move over the next few days. Will keep you posted.
[Samsung Galaxy S9+ Questions & Answers] miki89:
Yes, my issue was completely the same. I was able to make a call and than in some point call dropped (but signal is not lost) and i have to call person again, also there is similar problem , when i talk to someone call doesn't drop, just earpiece become quit and can not hear other side. After update i had the same problem (ACC version) but than i restore to default and clean cash from stock recovery and for now it looks fine. I have couple of calls from than, some of them was approx. 30min and there was no drops. I will keep you post it.
[Samsung Galaxy S9+ Questions & Answers] IndDoc:
I am on the latest update that was supposed to fix this problem, but no dice. Call drop is abysmal, and the call quality is worse than an entry level dumbphone. Really surprised how a flagship can have such a glaring issue and pass quality control. No matter what the signal strength, I keep getting call drops in the middle of calls, and garbage, messed up audio intermittently. Coming from a Xiaomi, it's sorely disappointing to see this. Hope Lolsung fixes this soon.
[Samsung Galaxy S9+ Questions & Answers] rochitka:
Silent patches in calls for my S9 plus Exynos version, dual SIM, bought directly from Samsung UK website - goes silent for me for a few seconds intermittently in calls, although the other party can still hear me.

Want to return for refund as already git burnt by a bad samsung 'warranty' experience with my S7 a couple years back, don't want to risk Samsung deciding in their wisdom again that I've done something to the phone and charging me for a repair when all I've done is normal use
[Samsung Galaxy S9+ Questions & Answers] IndDoc:
I have this exact same issue. Wtf Samsung.
[Samsung Galaxy S9+ Questions & Answers] Geekser:
It seems to me that this must be a HARDWARE Issue and not software because it is not universally happening to everyone - but seems isolated to a few hard hit people like us. Doesn't that seem to indicate that this is due to something in our specific devices and that a replacement phone should correct the issue? Maybe I am wrong, but I would think if it was software issue everyone (or at least a bunch more than the ones who have complained here) would be having a problem.

I sent mine back after the Holiday (The store I purchased from is closed until after Easter) I should be getting a replacement from them.
[Samsung Galaxy S9+ Questions & Answers] searley:
No because some people have had multiple handset with same issue
[Samsung Galaxy S9+ Questions & Answers] dinysam:
Could be, although the replacement S9 I got was from the same supplier (Harvey Norman) only 5 days later so could have been manufactured in the same batch... and it had the same 4-6 seconds of silence problem from the first call. I have loaded the newest firmware today but will only know for sure if this fixed the problem after a few days of business calls next week.
[Samsung Galaxy S9+ Questions & Answers] DemonSoul:
Well i just got this silent thing on my calls for a few seconds, what should i do? i just got the phone should i go to the store and ask for a new one?
[Samsung Galaxy S9+ Questions & Answers] welshandy2322:
Popped into Samsung today for them to look at my phone regarding the call drop outs. They did all test and it came back as a fault with the antenna or sim card. So popped into vodafone for a new SIM as Samsung thinks it might be because the SIM is like 2 years old. Anyways all is working fine again I'll test it more over next few days.
[Samsung Galaxy S9+ Questions & Answers] DemonSoul:
The thing is i didnt get any drop i just stopped earing for a few minuts , im probably going to get a new sim this one as 4 or 5 years already
[Samsung Galaxy S9+ Questions & Answers] Dark5tar:
Try factory reset and clear cache like what the other guy did. It fixed his problem with the new firmware after doing this.
[Samsung Galaxy S9+ Questions & Answers] docker_rob:
3 days in since installing the Patch and the problem of 5 - 10 seconds of dropped calls is back again

So the Patch has not worked for me and the problem persists.
[Samsung Galaxy S9+ Questions & Answers] ratsalad:
Getting the same issue here, this is the second S9+ that I've had, the other was replaced because of the quiet notification problem but on reflection this call drop-out issue was on that device too, the replacement hasn't cured either issue, nor did updating to the newest ARCC firmware, it happened twice during a call with my daughter yesterday, the call doesn't disconnect just goes silent for about 10 seconds.
[Samsung Galaxy S9+ Questions & Answers] Sim-1:
Same problem (3-4 seconds mute during call) even here in Italy. I swap my sim card very often between my Galaxy S9+ and my Pixel 2XL and the problem only happens here, therefore it's definitely something to do with the phone rather than the sim.
[Samsung Galaxy S9+ Questions & Answers] denzel09:
Buy new sim and change it with the old one. ;)
[Samsung Galaxy S9+ Questions & Answers] Sim-1:
As I said, it’s not a sim related issue. My SIM card is just 6 months old anyway.
[Samsung Galaxy S9+ Questions & Answers] denzel09:
Stange, i have not problem with TIm and no brand
[Samsung Galaxy S9+ Questions & Answers] enikou:
Any other feedback guys?

In a greek forum there are already 3 persons declaring this issue (call drop), including me.

Unfortunately the last update is not yet available in our region (EUR), so i haven't had the chance to test it, but after reading the above posts i am pessimistic...
[Samsung Galaxy S9+ Questions & Answers] searley:
Not sim related. I went to Vodafone and did a sim swap first call after swap failed in the same way
[Samsung Galaxy S9+ Questions & Answers] dinysam:
Installed G960FXXU1ARCC. Problem seems reduced (~4 seconds midway in a 17 minute call - compared to multiple intermittent silences of ~6 seconds), its still there. This time I have a recording of it from the receiving phone. View attachment 4464148
[Samsung Galaxy S9+ Questions & Answers] Rapier:
I saw someone asked in the first page but haven't check all replies to see if someone actuall tested it.

I had the same issue in the past with an S6 Edge and it was due to the VoLTE setting (4G call). Initiall I switched it off from phone settings but later I flashed a ROM that had no settings for that and I had to disable the service FROM THE OPERATOR on my phone number in order to fix the anoying dropped call issue. Most of the times, the call was dropped after 1 to 5 minutes regardless of the signal strenght or location.

You could test this and see if it works for you.

NOTE: I couldn't find a pattern how phones are affected...some are and some are not. Not all phones having 4G call/VoLTE active have the problem, but from what I've tested, all persons (colleagues and some friends) that had this issue had it solved after deactivating the service
[Samsung Galaxy S9+ Questions & Answers] miki89:
after couple of days of testing with new rom and factory resrt after that.. today i notice bug again for the first time.. someone is calling me and before i answer the call, the call has been dropped.. so the problem is still here but it i much better than before..
[Samsung Galaxy S9+ Questions & Answers] misiokicio:
hey all, glad i am not the only one around then, its definitely samsung lads, nothin to do with network, UK vodafone and experiencing exact same problems with calls droppin out, had s8 before than with same sim and had no such issues at all, tried all like factory reset etc, and diff phones... only affecting s9, also to note here, sometimes when whatsapp message comes thru when on call... call drops too, not every time but it does happen too, its extremely annoying, no volte here,
[Samsung Galaxy S9+ Questions & Answers] Dark.Soul085:
Hello there

Im having the same issue like everyone here, almost every call drops for 3-4 seconds , I replaced my S9+ with a new one yesterday, once i recieved my new phone I've put the sim card into the phone with fresh install without any apps or old backups, I wanted to make sure if there is any app or old files is causing the issue, then i called my friend and it happened again after 2 mins.

I personally think its a software issue and its happening everytime the phone is switching between 3G/LTE.
[Samsung Galaxy S9+ Questions & Answers] enikou:
Exactly

I am fully convinced that the problem is initiated every time that the phone goes from 4g to 3g/hsdpa and vice versa.

Today we received the ota update (ARCC) here in Greece and the problem still persists...

Guys, lets send bulk messages to Samsung via email or Samsung app, or else they won't dig into the matter....
[Samsung Galaxy S9+ Questions & Answers] denzel09:
lock on 3g only and see the difference
[Samsung Galaxy S9+ Questions & Answers] jrharvey:
Dissabling VoLTE does not help just FYI. 2 more dropped calls today on Tmobile in the US. I get perfect reception but it happens on every single call. Not just a few but every call.
[Samsung Galaxy S9+ Questions & Answers] enikou:
I did. And for many consequent calls not a drop.

The thing is that I am not going to stay on 3g, only to be able to use the phone. Its ridiculous and Samsung should solve this imminently...
[Samsung Galaxy S9+ Questions & Answers] denzel09:
I think this is not a problem for samsung now, or we will have already had a statement from them about this specific problem. Anyway will not be solved "very soon" imho

Solution for now is locked the phone to 3g and use the 4g only for web surfing, etc..
[Samsung Galaxy S9+ Questions & Answers] bicubic:
In russian forum sameone told to change mobile settings PAP to CHAP ? I don't know what its mean but maybe it help
[Samsung Galaxy S9+ Questions & Answers] denzel09:
I don't think that setting can be a "solution".
[Samsung Galaxy S9+ Questions & Answers] miki89:
that settings is how your phone send your username and password when its connecting to mobile data.. :)
[Samsung Galaxy S9+ Questions & Answers] Geekser:
And that's the thing that bothers me most. THis is not a general issue effecting ALL Galaxy S9-Plus phones, if it was, there would be ton more people here complaining about it. But it appears to be a handful of phones -

This could mean one of several things:

Phones are defective in some way - a bad batch or some thing in the modem

Software on the phone is interfering - some other ap that we all have on our phones or some unique thing that each of us is doing similar.

In my opinion, it is more likely the first option.

I am getting a new replacement and hopefully will have it in about three days. I pray that I don't have problems with this one - and if I don't there is more evidence that it was something in the phone itself. I will report back when I get the new phone and let you all know if it is still happening or not. Fingers Crossed....
[Samsung Galaxy S9+ Questions & Answers] enikou:
Guys after latest ota update and after 2 days and two restart of the device, i have not faced the problem... Many calls in the meantime... Lets see how it goes.

Any other statements?
[Samsung Galaxy S9+ Questions & Answers] soullesstrance:
after two factory resets and cache wipe, the phone does not drop the call but most of them comes silent random times its better, but the problem is still there...will try to replace the sim card, but dont think it will help..
[Samsung Galaxy S9+ Questions & Answers] misiokicio:
anyone else with missing calls notifications not showing up on top of calls dropped etc?
[Samsung Galaxy S9+ Questions & Answers] denzel09:
never had these 2 problems :)
[Samsung Galaxy S9+ Questions & Answers] AlienSexGod:
Same here call drops and going silent at other times AFTER lastest update and cache wipe and rest. I should never have sold my S7 Edge... prefect phone particularly with Superman RoM!

edit my phone was one of the first delivered before the official release and was manufactured over 2 months ago in Vietnam!
[Samsung Galaxy S9+ Questions & Answers] fra.itc:
Random Silence during calls also locking 3G

The issue show less frequently but persist also using 3G only with my SM-G965F with Italian WINDTRE BUSINESS carrier.
[Samsung Galaxy S9+ Questions & Answers] soullesstrance:
the sim card exchange didn't help
[Samsung Galaxy S9+ Questions & Answers] denzel09:
For who have this problem send through Telephone app a message with the problem description directly to Samsung support
[Samsung Galaxy S9+ Questions & Answers] ratsalad:
I spoke to Samsung this morning, they won't replace the device but will take it in for 'repair' (this is currently the 2nd s9+ I've had) however Three.co.uk have agreed to replace it for a second time, but have said that if the issue is still there then it will have to be dealt with via Samsung's repair service, which will obvisouly mean no phone for a undetermined lenth of time, unsatisfactory for me, but although my confidence and brand Loyalty are taking a severe knocking with this handset, I have to give the 3rd S9+ a try...
[Samsung Galaxy S9+ Questions & Answers] denzel09:
I think that it's not an hardware problem. Being random i think it's a software problem: Oreo with Samsung Experience.
[Samsung Galaxy S9+ Questions & Answers] ratsalad:
I'd like to think you're right, and the issue with quiet notifications is almost certainly firmware related, I'm not so sure about this (call dropping/5 to 10 second silence during calls) is, it smacks of a hardware fault to me, but I have proven in the past (much to my dismay) that I could be wrong and I really hope it is firmware related, it does seem odd that some users haven't got either issue but others have one or both of them.... hardware can change during manufacture from plant to plant and supplier to supplier but firmware should remain constant throughout the process.
[Samsung Galaxy S9+ Questions & Answers] emix2001:
In Italy ther's a guy claiming tha teh issue has been solved, don't trust him much but await for feedbacks. Was the issue also on the sd845 version?

I don't have any problems with dropped calls while using the phone for close for a week now. Various calls lasting up to an hour. 4G and Volte. I am on T-Mobile Germany. CSC is DBT and i am on the latest official software.

[Samsung Galaxy S9+ Questions & Answers] Rifrafffff:
I have also had this exact problem with my S9 and today was issued with a brand new phone by Samsung. Let's see how this goes. I avoided transferring apps in case this is cause of the problem but with the number of similar problems reported here I'm not hopeful. :(
[Samsung Galaxy S9+ Questions & Answers] aussie1234:
Try This

Try this:

Settings - Connections - WiFi calling - Toggle to 'OFF'.

Hope this helps.

[Samsung Galaxy S9+ Questions & Answers] misiokicio:
it wont... seems to be affecting all exynos devices,

ny new s9 that was replaced 2 days ago, doin exact same thing, haven't done many calls yet, will be on the phone for much longer next week
[Samsung Galaxy S9+ Questions & Answers] zodiacr:
Had the OTA done on Sunday morning, thought it solved the issue being the 300MB+ patch that was addressing the calls subject.

To my disappointment it did NOT solve the issue, still having the 5-8s silent moments, either at the start or in the middle of a call, also dropped once (out of 15 calls today, at least 7 of them had issues)
[Samsung Galaxy S9+ Questions & Answers] ratsalad:
Yep, it's definitely a major issue, I'm surprised it hasn't made the press, I've had 3 S9+'s now in as many weeks, and all of them have had this issue along with quiet notifications on a lot of apps, the latest one was delivered at 14:30 BST today, I knew before I even unboxed it what the result was going to be.

To have Samsung actually acknowledge the problem(s) would be a start at least we could possible rest a bit easier knowing that something would be done about it eventually...
[Samsung Galaxy S9+ Questions & Answers] dinysam:
I have 4 more days of Samsung refund warranty so today I have commenced my final effort to self-solve. My provider is a Telstra MVNO partner - AldiMobile. Similar to Woolworths, Telechoice and Better Life which do NOT have VOLTE (confirmed). So I bought a new Telstra SIM and asked Telstra to turn ON VOLTE on that SIM service (which is by default off). I am testing this today which will confirm if these dead spots have anything to do with mobile tower switching/VOLTE etc. Will test a couple of days and take second S9 back on Friday if this workaround does not work.
[Samsung Galaxy S9+ Questions & Answers] ratsalad:
Good luck, this debacle is very quickly turning me against Samsung, I've never had as much trouble with any other device, my only course of action is to take it up with Samsung Repairs now and as I have sold my S7 Edge (one sorely missed phone right now) I can't be without a phone for however long it takes them to turn it around and get it back to me.

I shall be thinking long and hard before buying another one of their devices or at least wait a few weeks/months to see how they fare out in the wild as it were.

Although I'm really hoping this is resovable with a firmware update...
[Samsung Galaxy S9+ Questions & Answers] docker_rob:
Really looking forward to what you find here. I was thinking to do the same but you have saved me a Pre-Paid SIM :good:
[Samsung Galaxy S9+ Questions & Answers] Dark5tar:
I too have the same problem.

What is the Build Number on everyone's phone here? I live in NZ on Spark network and have today received an OTA update with

Build Number G965FXXU1ARCC.

Date: 22 March

Android Patch: March 2018.

It's the patch that supposedly has the "calling fix", but to my understanding it hasn't rectified the problem. I haven't been calling much to confirm anything yet.
[Samsung Galaxy S9+ Questions & Answers] varun.gid:
What i have noticed on my Exynos version is if im on a call for 20 mins, there will be few seconds of blank out in between where i cannot hear anything. weird.

.
[Samsung Galaxy S9+ Questions & Answers] ranagade:
I'm with Vodafone Australia. When I receive calls at my desk on my S9, there is usually 4 - 5 seconds intermittent silence. If I move close to a window while talking, then there is no intermittent silence. I have updated to latest firmware and still experience this issue. VoLTE is on from Vodafone.

My S9 is a pre-order. Got it 3 days before official release. Wondering if the first release batches are more prone to intermittent call silence issue.

I'll take my S9 to a Samsung Store this weekend.

Try to turn off dolby atmos....
[Samsung Galaxy S9+ Questions & Answers] sammyelrefee:
I have been watching this thread for a while as I was having the same issues. I ordered one from carphone warehouse UK on preorder. This came from their central warehouse and was delivered to my house. It had the silence during calls issue. I went back to the store and even one of the staff had the same issue with their own S9 which helped my case. The phone was replaced within minutes. Issue persisted. Returned to store and another replacement issue. The issue persisted with the 3rd handset and this was returned for a full refund. Fast forward to now. I ordered a s9+ in blue (as opposed to black in original order) and it arrived today. I haven't had any issues with my 4th! Fingers crossed!
[Samsung Galaxy S9+ Questions & Answers] fra.itc:
too soon to be happy

Sorry... the issue persist but the duration of gap/silence is shorter....

Most frequently with the same people with Italian Provider.

Calling US (many long calls) and France numbers never get the issue....

My opinion is that the patch released with G965FXXU1ARCC update was a quick fix the issue but they are still working on it.

I hope soon. What I hate is that vendor test more the camera and smart features than the first phone function.... ...be able to call flawless....

Hurry UP!
[Samsung Galaxy S9+ Questions & Answers] dinysam:
One day into testing with a Telstra SIM VOLTE ON instead of AldiMobile. HD calls were very good in 4G zone but not that good moving into 3G zone (my in house has a 3G signal booster). However, there were no noticible silent spots over about 1 hour's worth of calls. Definitely SEEMS better. Also going to test Telstra SIM with VOLTE OFF and check if that is still better or not.
[Samsung Galaxy S9+ Questions & Answers] docker_rob:
Thanks for the update. I'll be interested to hear how you sit after a week or so.

For me Since I installed the latest Patch (on the recently replaced handset) it has been better, but not perfect. In 2 days since Patch installed I have had 1 x calls with the 5 - 10 second silence problem. Still better then pre the patch with this handset when I had 5 - 10 dropouts in the 1 call! But it could be I havent been on the phone as much, just not sure

Not sure if you are aware or already posted but the advice on their official support page is to report error log within 15 minutes of the issue occurring. Can be found here https://eu.community.samsung.com/t5/Galaxy-S9-S9/S9-speaker-phone-cutting-out-on-call/td-p/451835/page/12
