Thank you very much for letting me know, @syaoran . My SIM is about 7 years old.
Actually, restarting the phone potentially resolved the issue… I will see how it goes later today and if I could make calls.
Hi! Maybe it depends on phone model. My phone is Samsung Galaxy A14. On my phone it is: Settings → Connections → Data Usage → Wi-Fi Data Usage. Do you have a similar option? What shows on your phone? Also, maybe apps are updating automatically (I think this is default option). In Play Store → Settings → Auto-update apps, you might be able to choose if you want apps to update automatically, and if yes - if this would be over Wi-Fi only. However, it is good to keep apps updated, so that they function properly. If useful, on my phone, two apps that use the highest amount of data are Google Play Store and Meta App Manager. Galaxy Store also uses a lot of data. Hope some of this helps.
The same issue also happens at least with Zoom. Sound is also leaking. However, I am able to decrease the volume more, so it is more difficult for people around me to understand conversation. I am using just a 3.5mm jack, not a USB-C adapter. I have not had an opportunity to try it with non wired BT head sets yet.
One has a mic, the other does not have a mic. Same results with both of them.
What is exactly the question? Does full screen work on s22 ultra?
I don’t know the answer, but have you tried checking which apps are constantly exchanging the data (on my phone this shows in Connections → Data Usage → WiFi data usage) and how much data are they exchanging?Also, some apps ask if we want to allow diagnostic data sent to them, which I think is usually optional. If this is happening, you could select no.Or, maybe trying another anti-virus could help, to confirm that there is no virus that stayed undetected in Lookout?
Not sure if this would be useful: there is E2PDF app which can send a copy of text messages (sms only and text only; all messages with a specific number) to email/Google Drive.
