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

    There’s definitely a business opportunity for hot swapable batteries. I really don’t understand why no one is exploiting this market. Construction, factory and all scale workers need phones and if they can hotswap battery they’ll gonna love that.

      They make rugged phones and tablets for industrial setting with replaceable batteries. But they are way more expensive that consumer devices of the same spec.

      Just curious, what situations do you find yourself in relatively frequently that a hot swappable batter would be more convenient?

      Nowadays w/ 15 SOT I don’t think I’ve actually needed one minus camping where I don’t really use my phone much anyways.

        Being able to rip the battery out when the phone locks up. Needing to make sure it’s actually off and can’t be remotely powered on. When it’s 3 years old and the hardware is still well up to the task but the battery lasts 4 hours.

          Being able to rip the battery out when the phone locks up

          How often does your phone lock up that that’s necessary? I used to have lockups a lot more but android is damn stable now, haven’t had one in years.

          Needing to make sure it’s actually off and can’t be remotely powered on

          Do you disconnect your PC’s PSU?

          When it’s 3 years old and the hardware is still well up to the task but the battery lasts 4 hours.

          Fair, but if you’re getting 4 hours SOT after 3 years, it’s just not a great phone. My current Note 10+ still pumping out 10 hours SOT and I’m a HEAVY user.

          Honestly in 2015 I’m totally on your side for this, but in the last few years I’ve never felt the need to hotswap batteries, and only slightly felt the need to replace it in general.

      Samsung does produce the xcover series for construction/industrial use. I seriously considered one, the issue was it would have been a downgrade for me in CPU, display and doesn’t have dex
