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

    Put me down for another complainer about the lack of IR blaster. I used my Huawei P30 as a remote for 3 different TVs, two different office ACs, and a workshop radio regularly. I also used it a lot when doing tech support for family for basic stuff like ruling out the remote not working on an AC for example, or accessing TV setup menus you can’t access with physical buttons on the TV and of course mums lost the remote again.
