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
The IR blaster on my galaxy s6. Not the most used feature, but when the Air BnB didn’t have all the remotes it was a life saver.
IR blasters were so useful! My HTC One M8 had one, and I actually made a lot of use out of it. I really wish this was still a standard feature on modern phones, especially these days now that I have even more devices connected to my TV.
I never even heard of that feature before and I want it.
Keep losing the remote to our TVs.
The Roku Tv is easy as the official app lets you connect if its on the wifi, the other one…not so much.
I still use the IR blaster on my s5 when I go out. I never have to get stuck with fox news playing when I have it with me. It’s from 2014 and still kicking.
It also works on a lot on window mounted air conditioners, weirdly.
