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
We got my legally-blind grandma a flip-phone with a notification LED on the outside. That little light has been a huge pain, because anytime she misses a call from a telemarketer/scammer or gets a marketing text, it turns on and she just. can’t. ignore. it. If that light is on, I’ve gotta drive all the way over there and clear the notifications.
I would like to ask about if you can not teach the poor old people some button combos to “mark as seen” but i imagine some old people want to know everything on their phone even if those texts and calls are scams and even they knew they are scams. Nevermind.
