Hello,
For many months I have had a strange problem with my S21 Ultra, namely it does not seem to show me at random times that someone is calling me, no matter if via the cellular network or some communicators, it simply does not show notifications that someone is calling no matter how is calling. I often have it that only when I pick up the phone, unlock it and check something on it, suddenly messages come that someone tried to communicate with me, and only from then on I can answer calls until I hang up the phone and in an hour or two the same problem - over and over again. I have such an impression as if the phone itself went into some hibernation after putting away, although I have no indications that something like this is happening, because everything looks normal. The phone has the latest update, and I have restarted it several times with no effect.
I would like to add that this happens both in an apartment where I have wifi turned on (I do not use lte calls), and when I am outside while walking in the city.
Is there something I can do to fix this?
This is a very strange issue indeed. Have you checked if your phone has cell coverage when the screen is off? Did you try calling yourself from another phone and number? If the answer is negative to either question, I would suggest resetting your network settings. If that fails, try a factory reset which should solve any issues. If the issue still persists, it could be hardware related and you might need to take the phone to Samsung centre to get it checked.
I don't have a second phone to call myself. Friends say that on their end it sounds like I am not answering the call (i.e. they have a call signal, but just nobody is answering). They have no busy or unavailable signal. What exactly do you mean by a network reset, what would I exactly have to do? I was thinking about a factory reset, but I'm afraid that I will lose all my data and application settings. I do not know if it matters, but I have been using this phone since the premiere of the S21 Ultra, and when I bought it, I transferred all data via the data migration service from the previous S10+ phone, to which a few years ago I similarly transferred data from the S9+, to which I transferred data from S8 + earlier
Maybe you have the "do not disturb" option on? When I have this on, I can't see who is calling me.
I checked, unfortunately it's not that, if it were, I would never see someone calling, but my problem seems to be random.

u need to go to settings>general>reset and there tap reset network settings..
Hi,
I experience very similar problem. I tried to reset network settings, "hard" reset the phone, playing around different mobile network settings... nothing helps. I'm not sure if it is phone hibernation issue or kind of removal of the phone from cellular antenna.
I have another phone I use to watch this s21ultra issue. Practically each day it happens that the s21 ultra does not react to my call, of course most of the time it works properly, but there are some tries, when it fails. In such case on the phone I call from I get a message "user is not available". But then, leaving the s21ultra untouched for 10 minutes I get SMS saying that someone tried to contact me, so it is not obvious that the phone hibernated.
I was not able to reproduce the problem on the other sim card put in s21ultra (the carrier is different). I was not able to reproduce the problem on the other phone and the sim card from taken from s21ultra. In my opinion it is related to "weak" mobile signal and kind of "sensitivity" of s21ultra to low signal quality.
I reported the problem to my mobile network provider, but I'm still waiting for the answer. Anyway, I'm going to do the following:
- ask for sim card replacement (cheapest option),
- (if above does not help) go to samsung service and ask to check the phone - I hope they have some diagnostics tools,
- (if above does not help) install the second sim card (from different provider) and configure redirection of calls in case of "user unavailable" - I know it is "stupid" solution - but at least one of the carrier should work
- optionally root the phone - Can anyone confirm if it may help? At least I could enable toggling airplane mode each minute

Hi, gang. I've been surfing the forum silently for a little while and got my G1 all rooted and hacked the other night. It's been awesome and thus far I've been able to resolve any issues I've had in the process.
This one is throwing me off but I know someone has run into it before. Sometimes when someone calls me, they say that it rings twice and then goes to voicemail. I never get any missed call notification or anything. It's like the call never existed. After testing, I found that data transfer is taking precedence over voice data when they both try to come through at once. It's really annoying!
Does anyone know of a way to reverse the importance of these 2 things? Obviously I want to receive my calls if they happen to arrive when data is transferring. My phone constantly accesses some sort of data throughout the day (only texts and email).
For reference:
- White T-Mobile G1
- ROM: OpenEclair v1.2.1 BACONWEAVE
Thanks in advance.
No one else has run into this? A friend said I could try a wipe and re-flashing the ROM and see if that works. I'm thinking of going back to Cyanogen and seeing if the problem occurs with that.
Roaming in Citrus Springs?
Check Settings/Wireless & Networks settings/Mobile network settings/Data roaming. The choice is to connect to data services when roaming. This should not be selected.

David,
I totally overlooked that setting. Before my phone was rooted, I apparently had disabled this but failed to do so after modding. I just tested it by loading a website in the browser and making a call to it while it was loading. The call came through without a hitch!
Thanks a lot. I had searched high and low but no one ever mentioned this. I thought I had already tried it actually, but I was wrong. Much appreciated.
Okay, apparently it was only a partial fix. If wifi is enabled, the web browser just defaults to using that (obviously). When I disabled wifi and loaded a webpage while calling the phone, the call went to voicemail after 2 rings and never showed up on my phone.
I've never had this happen before. I've only seen this after flashing everything required to root the phone. It's not a huge deal but it baffles me. I guess when you're not on 3G, it only allows data through if both voice and data are trying to transfer at the same time.
First of all, I want to say that I found people with the same issue using Android everywhere and with a lot of different phones, so it's probably an Android bug rather then Moto X itself, but I wanted to leave my report.
I came from an S3, which suffered from the same problem when using Cyanogenmod. When using official Samsung ROM everything worked as it should. Now, I'm getting the same issue on my brand new Moto X.
When I try to call someone, sometimes it just doesn't call, after I press the dial button, it just hangs (without ringing) and finished the call with a "Cal ended" message. It happens randomly, and sometimes I can't call anybody for like 2/3 hours.
The simcard has been changed from the S3 (micro) to the Moto X (nano), so it's probably not it. Also, with the Samsung ROM it didn't happen.
I can still receive calls and messages, and the signal strength is fine most of the time. I just can't call.
Today I faced this problem and then I tried calling from my girlfriend smartphone (samsung ace IIx) at the same time, which is from the same carrier, calling to the same number, and it just worked fine. Mine still didn't work though.
Here is a thread on people on xda facing the same problem, but with a different phone: http://forum.xda-developers.com/showthread.php?t=2351227
Don't know what to do.
i've had the call not go through as you've described, but have never had a phone not let me place "any call" afterwards. i always chalked it up to poor performance (limited RAM, too many processes, etc). My DROID3 would do it and often times when it finally did make a call, there was zero sound and I would have to reboot the phone.

Hmm, it doesn't seems like poor performance. I ended up every task and it still happened.
However, I noticed that when I check the "2G ONLY" option it comes back to work. Maybe it's something with the HSPA/HSPA+ connection.
it could be completely carrier dependent then. my experience has been with vzw.
Moto X "Call Ended"
I have experienced this same problem in Houston on the T-Mobile network after switching over to Android. My T-Mobile rep told me they have had towers vandalized for copper which has impacted service for them, I believe he said it was about 15 towers and 10K a pop to get things corrected. What gets me is I was on a Bold 9900 and while I had signal problems in the affected areas of town I didn't not experience the "call ended" issue. I can also call other T-Mobile phones from those same areas but not land lines so to me this seems like a possible network routing issue which I have seen before between specific carriers.
If the problem does continue I may have to switch carriers. T-Mobiles service was previously outstanding in Houston but recently had not been great after the 4G LTE upgrades. I support multiple hospitals and need service to work correctly and will work with the T-Mobile Engineers to see if I can make headway on that front. I noticed another MotoX user reporting he only had the issue when flying in to Houston for work and that everything worked for him outside of Houston. His solution was to operate in 2G mode which for me is really not an option. I have to handle a lot of tasks over the network while on calls.
Anyways I would appreciate it if others could post if they are experiencing these issues and give as many details as possible so we can try to isolate the root cause of this problem and if found to be a carrier issue we can escalate with them. Thanks

Call Ended Issue Resolved
Hi All,
I see this Call Ended Issue in many brands. So I assume the error is a combination of the Network along with the SimSlot.
I tried various combinations for my Moto-E mobile.
Before i post the solution i found, Let me provide a brief about the problem.
I use Vodafone network on sim1 slot and Uninor network on Sim2 slot. I started facing the call ended issue on my sim 1 vodafone network.
I inter changed the sim's and found the network working absolutely fine. This makes me to understand that the sim1 slot with the vodafone carrier has some network issue where that IMEI code has some problem.
i tried to place the vodafone sim again on the sim 1 slot and found the problem persists. So i came to that conclusion.
Hope this might help you and provide a instantaneous and temporary resolution.
Thanks,
Praveen.
Call Ended problem still going...
Hey,
I just rooted my Moto X (XT 1053), like 5 min ago, in the hope to fix this same problem. I`m no programer/developer and have nothing against rooting, I just don`t think I`m that kind of user. Anyway, about a week ago my phone started to drop my calls right after dialing. I restored factory settings, updated it and nothing worked. I took it for service and they offered to charge me 150 bucks to restore factory settings and update the software. So I was kinda forced to root and try to fix it this way. The problem is that I probably don`t understand half of what you guys say, so if there are any kind souls out there, please help me out.
To sum it up:
- No Sim Card error
- I get carrier services and can use mobile internet (3G because 4G is still too explensive here in Brazil)
- Directly drops my calls
- Won't receive calls
- Won't send or receive text messages via carrier (just over 3G or wifi)
I`ve tried another carrier's Sim Card, no go.
I`ve tried my Sim Card on another phone and it worked just dandy, so I really don`t think it`s carrier related.
I`m running Android 4.4.3, as the other updates weren`t available for my phone via Motorola. I thought maybe updating to a newer version of Android might do the trick. I just have no clue on how to do that on a rooted phone... or on a non rooted phone for that matter.
Can anyone give me any tips/pointers/etc... ?
Thanks!
I have the same issue with my moto x on Verizon. Have you been able to figure it out?
I bought a 2nd hand Z3 Compact recently and it seemed to work fine. But I noticed after a day or two that it was dropping the mobile network. When it happens I get only ”Only emergency calls” and no bars for signal in the status field.
I've noticed the net disappears after I've made a call or two (rarely can do 2 calls in a row). As soon as I hang up, the net drops.
If I restart it might work again, or if I shut down the phone and start it after a while, also sometimes when removing SIM card and putting it back in again.
I can send SMS/texts and surf as long as I don't call or recieve calls, then the net is gone as soon as I hang up.
Anyone knows why this problem occurs?
Software problem? I have done a factory reset but it's still the same.
Would anything change if I downgrade and root?
Hardware problem?
How do I go about to troubleshoot this, both software and hardware?
It's a D5803, 23.5.A.1.291, Android 6.0.1
The SIM card is new, I have tried it in an older phone with a SIM adapter and it works. Though the older phone uses only 3G.
Grateful for answers!
Hi there.
I have Note 9 without any brand. Updated to newest firmware that existed and about two updates ago there was problem - i cant make any calls. Restarts one helps, and other time don`t help at all. And now - it was no use to restart phone because of this problem. I felt that it might be this problem and i turned off this option and tried to make call - and nothing. Only when i restarted phone again - i can make phone calls normally like before. This problem exists not everytime, it looks like when i make call to my second phone it is only "connecting..." at my note9, and other phone is ringing. And there is two kind of behavior, first - in note i cant hear anything, just this "connecting..." message, and other phone after few seconds hangs up and ask about reconnect. And second - after few seconds after receiving call it finally works but it have take some time between receiving call at second phone and hearing anything. Its lottery.
Now i have this option disabled, phone is restarted and now i can make calls. I contacted Samsung via chat (samsung members app) and via Twitter and they said to me to go to their service to diagnose or sth, but i know what i will hear at service: "please reset your phone to factory settings and if then this issue will be present we will take your phone and try to repair it" but i don`t want to do this because of all this configuration and hours of clicking... I dont like to do this when i dont have to.
So my question - do you have similar or the same problem? Is WiFi calling have anything to do with sim provider?

Well need a few things to be able to help.
Carrier?
Model? I'm guessing N960I1?
What is the firmware version you're on?

And I'm assuming the carrier Support Wi-Fi calling right? It may be a provisioning issue. You should try contacting your carrier and verify Wi-Fi calling is a feature and that they support it on your device. They should also be able to help you activate it if they support it.
I wrote that it was working normally before, and now it stops. I`ve had this thing working.
Hi,
After OTA to A13 (5DVJA) SIM 1 is dead most of the time.
People say they can't call me, they just leave a message.
I get a text message that somebody called me......
Never had this problem before.
Hard reset did not help.
Anyone else had this problem?
My S21 Ultra has issues, and both sim cards don't work anymore. I had to reset settings factory reset still no joy.
I left my sim in, and after several hrs, it started working!
I also set up wifi calling, which helped, and it activated the sims.
However, the reception has been extremely poor so something has been damaged by the update, I assume.

It doesnt changes anything. Also Wifi calling is useless for me as nativ call recorded doesnt record call via wifi.

Wifi calling could fix the issue. Once done, you can turn off wifi calling.
Put the phone in aeroplane mode, then turn it off
Take sim tray out turn the phone off, insert sim tray then turn back on
others are reporting the same - you're definitely not alone
Nothing else works If under warranty, send to Samsung to repair
let me know if any of the solutions work
