Foreground: `apt update` indicates I'm up-to-date on everything. I'm on T-Mobile in the United States and I'm posting this just as an FYI as you prioritize what to work on.
When I first received the phone and before I updated the OS I could select cellular data speeds by groups (2g, 3g, 4g) or (2g, 3g, 4g, 5g). In the latest version I can't do that and the phone almost always connects via 5g but the signal is so weak (1%) that it's like having no connection at all. It'd be great if I could tell the phone to stick to 4g.
