And sometimes nav bar don't hide
This is probably the most annoying case of having the Navbar. I am hitting the Home button way to many times instead of pressing the Spacebar, plus it takes up some screen real estate fr viewing the conversation.
Anyway,, I'd gladly donate for such a feature !
This is actually why I'm not a fan of on screen buttons, not only do you lose screen real estate, but the continual disappearance, reappearance, and relocation of the buttons is jarring. I wish more phones kept either the hardware or at the very least, capacitive buttons. They're dependable and you get a consistent experience if they're always present and in the same place.
I realize I'm in the minority, as I am in my desire for smaller phones, but that's my opinion on the matter.
True it is super annoying, all that space taken from your screen with those soft keys, but again,, if they keep the capacitive button or even the hardware once that would require to have a bigger bezels (at least on the lower part of the screen).
So ether the device has to be big with relatively small screen or big screen with soft keys and small bezels.
Look at LG G3 and any other 5.5 inch screen phone,, just the relocation of all those physical buttons made that phone's front almost entirely screen, which you can't say about OnePlus One, OPPO Find 7 or iPhone 6+ for that matter.
Anyway, I don't even know what's the ultimate solution I like big screen in a small body and I also don't like soft keys so yea ))
