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
Fingerprint sensor on the back of the phone. So you’d pick it up and your finger would naturally fall on the sensor, so that by the time you look at the screen, it’s unlocked.
I also found these to work way more consistently than on screen fingerprint scanners.
Eh, I was worried about this when I got my current phone but I’m the end I like it much better. It’s just as reactive for me, and has the added bonus that I can unlock the phone while it’s resting on a table without having to pick it up, I guess I do that a fair bit because it was a pain point I felt with my previous phone.
Hadn’t thought about the table use case. Good point
I always put my phone face down so I have to pick it up anyway.

I’m still on the original google pixel, and I am dreading the day I’m forced to upgrade. It has the backside fingerprint sensor, and is in general pretty much the platonic ideal of a smartphone.
On my Samsung fold 3, fingerprint sensor on power button is awesome.
Works really fast and it’s very reliable. Much better than fingerprint sensor under screen in my old oneplus 7 pro.
Is this discontinued? My phone does this.
I think the most logical placement for a fingerprint scanner is power button>back>bottom screen=on screen
Except at current screen sizes, holding your phone such that the index finger is firmly in the middle of the back of the phone means you have barely any screen reach with the thumb.
You don’t have to leave your finger on the sensor while you use the phone.
