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

    This may sound dumb… An old Samsung phone I had years ago, came with alarms that gradually faded in. The most memorable, started with the ocean, and the seagulls… Then there was a fog horn in the distance. Slowly the horn got closer, and closer… Until it was all you could hear, and your alarm was going off.

    I’ve looked everywhere for the sound file… It must be Locked away in a basement at Samsung somewhere.

    One day I’ll find it
