Thank you for warming up the old thread

I just received the update to oneUI 5.1 for my Samsung A52 and VoLTE is activated by default and the setting option to deactivate it has been removed.

is generally called “progress” or “future”

Unfortunately, my experiences are a bit “mixed”:

For example, communication with a remote station abroad was significantly better when I switched off VoLTE - the remote station is in the digital “wasteland” where 3G (UMTS) is already considered “oh - WOW!” would be felt! - Is it possible that VoLTE is not the final answer if the connection rates between the transmitter and receiver differ greatly and you have to actively switch to lower mobile communications standards so that the other party can understand you?

(I’m breaking new ground in this regard, as the “advantages” of VoLTE simply weren’t worth the display space for the stupid logo in the already overloaded status line… - call me stupid…)

I just want to continue to be able to communicate easily with people outside the “1st World”, which has so far been difficult for me with VoLTE activated.

Maybe @GrandDixence knows more about this?

P.S. Please no comments: “Use WhatsApp or something similar.” - HELLO!?! - The remote station is happy if it only has a 2G mobile signal! - Mobile data is a complete no-go, only “simple” telephony works!

So far I have had a few foreign telephone calls via VOLTE, but all within Western Europe with remote stations in well-served areas. At best, other customers can report here in the forum about their experiences with connections to technically underdeveloped areas.

But that shouldn’t have any influence. Of course, if the person you’re calling only has 3G or 2G (abroad), the voice quality is generally worse, but whether I’m making calls via VoLTE or 3G, I’ve never noticed a noticeable difference. If necessary, you can still deactivate VoLTE by setting the network mode on your device to “3G only”.

In voice telephony, voice quality is assessed using the MOS value. See:

https://de.wikipedia.org/wiki/Mean_Opinion_Score

All “audio codecs” used in mobile telephony (also called speech codecs or audio coding) are adaptive audio codecs. Adaptive means that these audio codecs can adjust the transmission rate depending on the load on the air interface/cellular antenna. The biggest impact on voice quality in the past, today, and will continue to be in the near and distant future is the Packet Loss Rate. It is likely that the adaptive audio codecs can also adapt to changes in the packet loss rate. => Stronger or weaker forward error correction and so on.

https://de.wikipedia.org/wiki/Vorw%C3%A4rtserrorcorrection

The packet loss rate measures how many data packets are corrupted or not received at all by the radio receiver. In the 2G/GSM mobile network you can use the Network Monitor and the RxQual parameter to read out the packet loss rate of the data packets received from the mobile phone during an ongoing telephone conversation. I wrote down the following for the RxQual parameter:

The value:

GSM: RxQual

in the Samsung network monitor (*#0011#) corresponds to this
Bit error rate of the received mobile signal


RxQual = 0 BER < 0.2% Very good voice quality
RxQual < 4 0.2% < BER < 1.6% Sufficiently good voice quality
RxQual = 4 1.6% < BER < 3.2% Critical speech quality
RxQual > 4 BER > 3.2% Poor voice quality (unsatisfactory)

BER: Bit error rate

The bit error rate should be < 1% for voice transmission!

Unfortunately, to date I have not found a parameter in the Samsung mobile phone’s internal network monitor that allows reading out the current packet loss rate of the data packets received by the mobile phone in the 3G/UMTS, 4G/LTE or 5G mobile network. However, the packet loss rate in the 4G/LTE and 5G mobile networks is certainly significantly higher than in the 3G/UMTS mobile networks. Thanks to its radio technological advantages, the 3G/UMTS mobile network is now the most suitable mobile network for voice telephony. Regardless of whether AMR-NB, AMR-WB or EVS is used for the telephone conversation, the packet loss rate is crucial for the voice quality. The packet loss rate is largely determined by mobile phone reception.

Poor cell phone reception = high packet loss rate

Good cell phone reception = low packet loss rate

Here are my notes on the audio codecs:

Overview of the most important audio codecs
================================================= ============================

Generally
===========
At low transmission rates, AMR-NB and AMR-WB offer the best
Voice quality (8 kbit/s to 24 kbit/s). AMR-WB always offers better voice quality than AMR-NB. At very low transmission rates (e.g. satellite phone). AMBE offers the best voice quality (< 8 kbit/s). For high transfer rates (> 24 kbit/s), Opus offers the best
Voice quality. G.711 is used for analog telephones. HD Voice offers AMR-WB (G.722.2) and G.722. MOS values

Anyone interested in the topic of “audio codecs” should note the graphic “Why you don’t need high-fidelity sound in headsets” in this Heise article:

After studying this graphic, you can think about whether using EVS really makes sense. And whether all the information about the MOS values ​​could be correct.

@GrandDixence

Thank you for your - as always - well-founded answer!

I’m probably affected by the poor network coverage (it’s an urban area, but “Minergie”) and -109dbm / 31asu within the apartment should be anything but “intoxicating”!

May I once again claim your expertise and shyly ask whether the situation could possibly be improved via WiFi calling on my part? (I think I understood from your explanations that it is not due to the discrepancy in standards but solely to the signal quality of the transmitter side).

described in detail, the transmission power reserve should be at least 25 dB. At -109 dbm, the transmission power reserve is very likely significantly less than 25 dB.

WiFi calling is and remains an emergency solution. The disadvantages of WiFi calling (VoWLAN) have been discussed below:

[https://community.swisscom.ch/t5/Mobile/fragen-zu-WiFi-Calling/m-p/748222](https://community.swisscom.ch/t5/Mobile/fragen-zu-WiFi-Calling/ m-p/748222)

described in detail.

In addition, WiFi calling exposes you to an unnecessarily high dose of radiation, as WiFi does not have automatic, adaptive transmission power control (TPC). A cell phone always transmits with the highest transmission power in the WLAN (in the one or two-digit milliwatt range). And you don’t want to have something like that on your ear… => It’s better to use a cordless phone with automatic, adaptive transmission power control (TPC) (DECT or CAT-iq). See:

@GrandDixence

Thank you again for your answer!

The radiation exposure doesn’t really bother me because I only make planned phone calls via a Bluetooth headset and place my cell phone where it has the best reception - from my point of view.

The bottom line is that I think it’s better to limit your cell phone to 3G for future phone calls (as long as Swisscom/Wingo still supports it) and to look for new friends in better-developed “uncharted territory” after Swisscom says goodbye to 3G "to look around 😊

@GrandDixence

To add:

In addition to the packet loss and the codec you mentioned, the following transmission parameters also have a significant influence on voice quality:

Consecutive loss

Packet misorder

delay

jitters

Number of transcodes E2E

I don’t seem to have conveyed my joke with my “new friends” very well 😟

“Latürnich” I will continue to maintain my friendships with real people! (even if I had to “throw” carrier pigeons)

I’m sorry that I triggered your “bite reflex” against Swisscom renegades 😊

I also found a solution in the form of the “Samsung Band Selection” app, which makes the VoLTE setting hidden by Samsung UI 5.1 visible again. For me, therefore, “the world is in order again” 😁

@“x”#107468Thank you again for your comments on packet losses in “normal” telephony using the “advanced” mobile communications standards! (It looks to me as if the providers today have classified the actual telephony under “also ran” - without realizing that they are thereby sacrificing their primary clientele - and income! - to the American “messenger services”)

That’s exactly how I see it too. I use a Samsung s22 and mainly an s21 5G and a Samsung tablet s8 5G with the latest operating system (the tablet with a Samsung keyboard). For all three devices, any additional energy consumption cannot be determined. Even with normal use in the evening, I still have at least 40% battery charge on all three devices. This was never the case with previous devices (including Nokia).

Thanks to LTE, I have excellent voice quality if the other person also has LTE. This means you quickly notice when someone is calling without LTE - it’s difficult to understand each other. One of the reasons I’m staying with Swisscom is knowing that good quality doesn’t come cheap. The following conditions apply to me when purchasing a cell phone:

1. Not bigger than the s21 5G or s22

2. LTE available

3. at least 128 GB memory

I am very satisfied with Android 13, One UI 5.1. However, I use the Nova Launcher Prime user interface on all devices. that I no longer want to do without.

It’s very easy:

Swisscom asked Samsung to remove the VoLTE option/setting. With another provider the option is still there (tested with S23+ & Sunrise).

This was written by Samsung in response to my Samsung Members blog post.

Which is completely true. There is actually no reason to consciously deactivate VoLTE, except in special individual cases. Without VoLTE, voice telephony will soon no longer work anyway, as Swisscom will stop using 3G at the end of next year, and Sunrise will stop using 3G in just over a year. In other words, when buying a new mobile phone, make sure that VoLTE works, which is the case with almost all current smartphones, especially Samsung, Google and Apple. Problems can only arise with very exotic brands.

Show original language (German)

Indeed. I switched from Salt to Swisscom today (Samsung A54) and the VoLTE activation/deactivation disappeared.

So according to your last post this is OK and not a problem at all?

Thank you very much
