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’m not sure exactly what it was called but any time you took a photo with a Note8, it was always taking photos from right before to right after the photo. This resulted in much fewer garbage photos because a few frames before or after the shutter was pressed would be a better photo, one that is not blurry! Now instead of a useless photo, I would have at least something workable. I have not seen that on any other phone with this feature, including my current one.

      It can’t know when you’re going to press the shutter button, so it has to actually just record video all the time. Taking snapshots from video is much lower resolution and quality than properly exposed photo.

        Yeah, but the average consumer doesn’t care. I’ll share a photo from my camera to someone who’s sharing a smeared shitty blown out phone picture back, and it’s just depressing.

      I think live photos on iphones come sort of close. you can pick a specific frame after taking a picture and it records a bit before and after you pressed the shutter button

      though for that to work you have to keep “live” on and it eats space much faster that way

      For folks with an iPhone, iOS Live Photos does this by recording 1.5 seconds before and after the picture as a short video, and allowing you to choose the key frame that shows as the still image.
