Not sure if this is an S6 issue or android related, but the keypad for the pin on the lock screen is very slow in registering taps. It comes down to 2 issues – if I go too fast it misses registering one of the pin#s, and/or it has a very small area where a # can be touched. I don’t have this problem with any other part of the phone (i.e. when it is unlocked) – everything else responds as expected to my touch in the OS or any apps. Even after a full reset back to stock this persists. I had an s3 previously and never experienced this kind of issue. Anyone seen this, and/or any advice to improve? Thanks!
