What discontinued feature do you miss from phones or other technologies?
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
You can still buy Android phones that have manufacturer support for unlocking the bootloader. Once that's done obtaining root is trivial. Pixel phones notably support this. Personally, I only buy phones I can unlock the bootloader on to show the demand for this feature. It doesn't matter to me how great a phone is otherwise. Can't unlock the bootloader? Not buying it.
That said, I completely agree with you. We all pay for and own the hardware, but let the manufacturer dictate what software it can run. That's like buying a car and letting the car company tell you what roads you're allowed to drive your car on. I don't really blame the average use for not giving a crap because end users will never care about this stuff as long as their basic needs are met. It's a failure of the people in the software industry to stand up for the open systems that built everything we have today. Without that constant fight for openness companies are going to be more than happy to take advantage of a locked down system to create a competitive advantage. Hell, look at what Google is currently doing with WEI in Chrome. If they have their way, the web will become just as locked down as smartphones are now.
For the record, it still is.
Only problem is all the apps that won't run in a rooted environment. I'm not sure why they should even know that information....
there's some projects that exist that try their best to hide root from specified apps to make them seem as if they aren't running in a rooted environment of course, they can't completely hide all traces but most of the time they're usually actively updated to make most apps seem as if they really aren't running in a rooted environment
