After Samsung dumped their failed Exynos CPUs maybe it’s time to dump their Exynos modems too.

Thanks for the heads-up!

BTW, I couldn’t find any “WiFi Calling option” on my Samsung phone: since I generally keep WiFi on the phone disabled I’m guessing that option may be visible only when WiFi has been enabled.

As for the “VoLTE Calls option”, this was enabled on my phone and I’m relatively sure I never messed with this option before, so I guess that – at least on some phones – this option is actually enabled by default.

Shutting down WiFi calling is fairly straightforward on my Galaxy S23 but it doesn’t seem to have a setting for VoLTE. The only options are allow 5G/LTE/3G/2G or deprecate to LTE/3G/2G or LTE/3G or finally 2G. There is no mention of VoLTE. Could this mean that the S23 doesn’t have the affected chipsets?

The Galaxy S-23 was not on the list.  They have the Snapdragon 8 Gen 2 chipset.

Desktop Asus TUF X299 Mark 1, CPU: Intel Core i7-7820X Skylake-X 8-Core 3.6 GHz, RAM: 32GB, GPU: Nvidia GTX 1050 Ti 4GB. Display: Four 27" 1080p screens 2 over 2 quad.

Thanks much. I tried to find out from Samsung support if the S23 was included but I might as well have been asking them for the weight of the moon. Thanks again.

It is super annoying that Samsung hides some settings. Try Samsung Band Selection app.

Thanks!

Pixel’s may be able to get the March 2023 update with the fix. Depends on your carrier or if you have an unlocked phone. Google Help on forced update of Android phone at https://support.google.com/android/answer/7680439

My A50 has WIFI calling off. My VoLTE is toggled on; if I toggle it off I can’t make calls! How do you use a phone that you tell not to connect to the network? What am I missing?

Exactly. I have a friend with an A03 who can’t find the VoLTE toggle and one with an A50 who can’t make calls when VoLTE is toggled off! I thought all 4G and 5G calls were VoLTE now and that one reason 3G isn’t supported anymore is that it doesn’t support VoLTE.

what about Samsung tablets and/or laptops, Susan?
does this only concern Samsung phones?

I’ll check but I doubt it because while they may have a cell phone number (in the case of the tablets if they have cellular) you can’t call them.  As I understand it the method to gain access is via the silent “call”.

Per this How-to-Geek article.

Samsung smartphones powered by Exynos chips, such as the European model of the Galaxy S22.

Following a trail of a few links from yours, I discovered my North American S22+ uses a Snapdragon chip. A bit of a relief.

Apparently these vulnerabilities affect devices using specific Exynos chips from Samsung.

So, are we certain that these serious vulnerabilities only affect the devices listed and not, say, other Android phones such as those from Xiaomi or Motorola?

Personally I am not affected by this issue since I only use iPhones myself but my father has a Xiaomi phone so I thought I should try to confirm.

I also find it surprising that there are posters here saying their Samsung phones can’t make calls when Voice over LTE is off. Surely you can still call others without using 4G/5G using a phone? Am I missing something here?

Hope for the best. Prepare for the worst.

Error, please ignore. Sorry.

Those were the steps given:

How to turn off WiFi calling on a Samsung phone

1. Open the phone on your Samsung phone
2. Tap the three-dot menu in the top-right corner
3. Select Settings
4. Find the WiFi Calling option about halfway down and toggle it off

Just reporting that my Samsung A21s phone recently notified me about the availability of a new update. Unfortunately, the notes for the update are pretty much succinct and it is not clear at all whether the update is meant to (also?) address the vulnerabilities at issue in this topic. The notes merely report the following:

Galaxy A21s (SM-A217F)
Build Number : A217FXXS8DWC2
Android version : S(Android 12)
Release Date : 2023-04-17
Security patch level : 2023-03-01
• The security of your device has been improved.

Also, a user of a Samsung A13 device that recently received an update is complaining about his phone now shutting off due to excessive heat during e.g. videocalls, whereas this did not happen before the update. Did anyone else hear of/receive similar complaints or experienced something similar first hand?

For Samsung phones, the April update includes a total of 66 fixes for security flaws, which includes the original 55 listed by Google. One of the fixes resolves a flaw in Exynos chips and Exynos modems that are found in global variants of many Galaxy phones. Last month, the March patch fixed issues that affected the security of Wi-Fi Calling and VoLTE. For many devices, this is still a problem, and so we suggest disabling the functions until you have received the April patch on your Galaxy phone.
