> I have a 3a and it has kept me using pixels mainly for this reason

Same here - I held onto my Pixel 1 & only jumped to 3A when it came out.

Mostly it was that I had an existing wired setup fitted to my ears, but the real reason to hate BT was that I wasn't always charging them up. The airpods style charging case + a charging mat might have solved those problems, but the charger was more annoying than the wires themselves.

I happily use bluetooth in the car, which doesn't have the same sort of "did I forget to charge it?" problems.

Ironically I'm in the opposite boat where I use bluetooth almost always except for when I'm in my car and wire it to the AUX. That's probably because my car is really old but also because it's nice to not carry my phone around everywhere when I'm listening to something. With bluetooth I just leave the phone on the table and can move around the house pretty freely.

I have a 3a and it's mostly fine.

But an obvious problem is that the touchscreen is activated by my leg. I had to actually lock the lockscreen just to prevent the phone from constantly opening random apps and providing random input.

I have this issue as well. What do you mean "lock the lockscreen"

Apply a pattern or code-based lock to make it difficult to activate the phone. It's a security setting.

I have a x digit code. I need a lock screen for my lock screen - to stop me from hitting play on spotify, audible, libby, pocketcast, etc.
