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

    Screen scanners seem much more sensitive to dry and callused fingers than dedicated finger print scanners of old. Some can’t even use it because their skin texture isn’t picking it up well, or have to do things like lick their finger before using which is gross. I miss the power button scanners or rear ones.
