What discontinued feature do you miss from phones or other technologies? (lemmy.zip)

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 had an htc one that could transmit IR signals meaning you could mess with TVs and other simple wireless electronics. You could also use the headphone wire as an actual radio antenna.

I used the IR blaster all the time. I really miss that feature and the headphone jacks

I still have an IR blaster on my Xiaomi Redmi note 11, never used it though

The one with the radio antenna! I remember it but from my Galaxy S2 mini or something from that generation. I never used it, but it blew my mind back then.
