In a similar position as OP and recognize most of what they're saying. > Modem: Frequent disconnects, not receiving calls Something I believe to be observing is that the phone can stay consistently connected for days if stationary but as soon as I take it out for a drive or longer walk I immediately start getting the disconnects, which I so far have only been able to resolve by a full reboot[0). This seems to indicate that switching towers and/or disconnecting triggers it. > Bluetooth Audio At this point I'm realizing OP may have a masochistic leaning. But props for pushing and no kink shaming :) Aside from the modem dying, my biggest pain-point is absent in the post, despite running a fundamentally similar software stack. Ranfomly, audio will not work in calls. Sometimes it's flawless. Sometetimes I can not hear the other side. Sometimes the other side can not hear me. It happens often enough that it's barely worth the hassle to make phone calls if I can avoid it. Regarding TOTP apps: https://github.com/grumlimited/authenticator-rs https://github.com/grumlimited/authenticator-rs is very close to being a nice experience. It's already functional and stable, needs what seems to be mostly a couple of simple UI tweaks.
