In my knowledge, every samsung phone has built-in call recording to turn it on, go to phone > three dots on right corner > settings > record callsIf it does not work on, then turn off WiFi calling and then try
I'm not sure, but it follows the timeline rumours that are recently circulatingThe only difference is that the S24 series should get a week earlierBut these dates are leaked from samsung's online meeting, so yes
After it restart your device If this doesn't help than install any third party app and force your mobile network to a specific spectrum band of your network supplier If any of this helps you than click on 3 dots and accept it as a solution
If 4g networks are available in your areas than in settings >connectivity>mobile networks> LTE only I think this can help you in improving netwwork speed
