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
Which banks were that? Which country are you in?
Four Russian banks, two Czech banks. Yes, it’s a narrow sampling, but 0/6 of them requiring safetynet is significant.
Dude I am not in any of that country. And have tried many banks here none of them works without safetynet and that is significant for me enough to avoid rooting and modding.
