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

    I miss my smart watch waking me up outside of detected REM sleep.

    On the Microsoft Band you could set a time window where the alarm would go off - say between 0700-0800. If you’re in REM sleep at 0700, the alarm stays off until you naturally rouse, or 0800.

    I’ve worked as a sleep scientist for 7 years, and the idea of not being woken out of REM is such a neat idea, and yet no other watch seems to do it.
