For me its the ‘Knock Code’ that LG had on their phones (I really wish LG still made at least the V series phones)
Basically there was a four-square area and you set up a sequence of where you would tap to unlock the phone. That set of squares was only shown when you set up the code
Then, to unlock your phone, you would tap those areas in the sequence you set up (even with the screen off).
Fingerprint readers are nice, but I really do miss the knock code
Edit: did find this article with a way to do the knock code, but if done wrong, could brick your phone I guess.
Plus, article is from 2014. When I looked at XDA’s info on it (they also being the developers) it looks like development on it is over, but individual modules may or may not still be supported by their devs
The only phone I had to even consider changing the battery was a Windows phone in 2015 and the replacement battery was the same age (and degraded state) as the old one. I don’t get the need for quickly swappable batteries.
The real key to making this work properly is standardized battery sizes. You know, like the AA and AAA standards we’ve had for one hundred years.
“Real” batteries would be too big because they need casing. Phone batteries on the other hand are fragile, because: no casing.
As I said, there’s no need for quick-change batteries like in an xbox controller, because most people can go years on a single one.
But a self-service battery change when it’s ruined should be a thing. Preferably without glued-in parts.
