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
This is exactly why I’m so resistant to using Bluetooth over wired solutions. My phone is Bluetooth only, and sometimes it takes a minute or more to pair with modern devices. I think it may be because I have multiple devices, but whatever the cause, it’s really frustrating when I remember being able to plug in to those same devices directly in a matter of seconds with my previous phone.
That’s how I felt until I took the leap and got me a not-shitty pair of wireless headphones. Now I’m never going back to wired honestly. My HD 350BTs, which are not too expensive as far as wireless headphones of that segment go, require charging once every few weeks, they sound nice (not great), and I haven’t had connection issues even once in the 9 months I’ve had it. I honestly think the technology is there now.
Though BT is great when out and about, I don’t see a wireless pair replacing my open backs that I use at home any time soon.
