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
IR blaster. You could have a universal remote app and control any tv from my palm PDA
100% this. I used to be able to control my ceiling fan, my portable a/c, and my TV from my phone.
Now I have to use the fan remote, the a/c remote, and install and create an account with some stupid TV app.
…it was also fun for changing the channel of TVs at bars & restaurants.
This brings memories back for when IR data exchange was a thing and you had to carefully place two phones head-to-head and not move them for minutes just to transfer a song lol.
One of the reasons I had Xiaomy phones in the past 5 years. Many models still have IR blaster.
Funny thing is I work for a company who manufactures products with infrared sensors and we have an app specifically for IR capable snartphones to fine tune these products. In the past 5 years I did not see a single client who would have IR on their phones, so basically the app is not used by a single person anymore. Either this or they can buy our official remote… for 200 euros a piece.
Pubs were fun with these.
Same with screwing around at school
There is a USB-C IR blaster that exists, but the Tiqiaa/ZaZaRemote app is awful.
Do you know any app alternative?
I didn’t find an alternative, when I looked a few months ago.
Yep. My final phone to have one came with this app to control it that was straight malware. Force click a pop up every time you open the app type shit. I still miss it
I remember seeing these everywhere and was super disappointed that by the time I could afford phones not bought at Dollar General, they weren’t a thing anymore.
Not everything uses IR blasters anymore.
