Serious reception problems

I'm experiencing reception problems with my phone. The first two weeks this was not a problem but end of last week and yesterday and today I'm having troubles with the phone. I have between 2-5 bars (average 3) when talking and I'm always calling from the exact same location and same room (working from home).
The problem is that after a few minutes I can't hear the other person. The person calling me can hear me without problems but I can't hear him. So I hang up, call back and the same happens after a few minutes.
I have tried with and without headset and also tried to soft reset it without result. Any ideas what to do? Anyone else experiencing the same problem?

No idea sorry! But I don't have that problem. Do u have a SIM card from another provider to check?

Yes, I might be able to try that or I'll try to get it replaced. Looks like no one else is experiencing the same.

I to am having some serious Reception issues but im with Optus in Australia. When on 3G at home.. cant make or take calls. So i have turned it to just GSM so i can get calls and make them.. Sometimes I did get calls and messages on 3G at home.. but today, it just wouldnt do anything..
There are updates from other counties which seem to have a radio update.

Hi,
Is there any way just to extract the Radio upgrade ?
I have my Diamond 2 in french, and want to keep it like that.
I wrote to the french HTC Support, and they just ask me to :
- Hard reset the phone : Done and useless
- Change the sim card : not done as the sim card I used is completely new
- Disable encryption : disabled and useless....
So the only solution will be a radio upgrade only.
Thanks

[Q] Lag while receiving calls and SMS issue

Hi everyone, I'm using Stocklite v8 custom rom, I am facing following issues,
1. Even when I have good network coverage (around 59 dBm) there is a huge lag while receiving a call. A caller to my number have to wait for around 20 seconds to receive a call, so sometimes the caller may end the call thinking my number is unreachable.
2. I don't receive SMS many times especially from web (e. g. I have not received SMS in first attempt from google when they wanted to verify my account) . I checked all the settings from my service provider but they said everything is fine.
I logged a complaint to my network provider but they think everything is fine. I even bought new SIM card thinking if the old one is causing problem, but still facing the same issue.
Even before Stocklite I was using Apocalypse rom & I was facing the same issue. So is it Android that causing me the problem?
Plz help me. Thanks in advance.

[1] Did you tweak some clock speeds, coz sometimes in roms they tweak it when your phone sleeps its clock speeds go down like 100mhz then when screen is on its back to full speed. And why do you have to wait 20 seconds??
[2] Try to go to airplane mode and turn it off, reboot. If that didnt solve your problem then apply a pin to your sim card, when i did that i can recieve sms.
Hope this solves your problem

Thanks for the reply.
[1] Yes, I did check some of the clock speed tweaks & Minimum RAM tweak. But unchecked all these tweaks & then tried it but still the problem is persisting.
The problem is that sometimes when people call me they don't hear my caller tune for around 15-20 seconds & able to hear the tune after I receive the call although there is good network strength. So most of the people don't wait for that long thinking my number ain't reachable & end the call. But if they give another try just after the first attempt, they get a reception from me within 5 seconds I hope u got my point now.
[2] I did try that airplane mode trick but seems it's not working for me.
As I already said this issue doesn't occur everytime, but it happens randomly & very frequently. Also sometimes I get duplicate SMSs from my network provider. They checked everything from their end & confirmed that it's not a network related issue.
So, I believe it's my phone which is causing me this problem.

Try not using internet
Try not using internet when not in use..
try uninstalling apps which enables when a call is made or recieved like shaplus caller info and truecaller or call recorder.

I had installed call recorder once long time ago, but I have already uninstalled it. Other than that I have apps such as hangouts, clean master,google settings etc & rest are multimedia apps, but I don't know if they interfere during calls or not.
I have noticed one thing that the mentioned problem occurs mostly when my phone is in idle state, but it occurs when the screen is ON & when the phone is busy as well. I have already unchecked all the speed tweaks in my phone but still no solution found.

Thanks I actually found out that its the problem with the phone itself. I tried to check on other handset and I didn't face such issues.
But now I am facing another major issue.Whenever I change my sim card and insert it into another phone, my dad receives an sms from number that says my IMEI has been stolen and everyday my phone credits get deducted. I dont know whether i have ever enabled change sim alert option or not but I am unable to find out that option in my stocklite v8 rom.
Please tell me how to disable that option in my phone, I am running out of my credits.

Losing mobile network, strange problem

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!

Question S21 Ultra sometimes doesn't show that someone is calling me

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

Question 😠 SIM1 is dead after upgrading to UI 5.0

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
