A few things that are a little strange, the navigation bar can be changed to gesture swipes which is great but what happened to the ability to disappear the navigation bar with the little dot on the left in the nav bar; which maximized the screen, also the ability to change you nav bar colours ?
Also in Samsung internet the ability to use fingerprint to go into secret mode seems to have disappeared, you can use iris scan but not fingerprint anymore.
These are the only things so far in the new 9/pie software update that are sticking points for me, however there are lots of other cool features for me so far the best feature is lift to wake, pick the phone up and it wakes to lock screen, look at it or place your finger on the scanner instantly open Great feature Samsung
The fingerprint to enter private mode is very annoying. Hopefully this will get patched quickly. Hadn't even noticed the navigation bar issue. Seems a good update so far but the missing fingerprint option in private mode is frustrating.
