Hello, I just received the phone and wow it's great. I'm coming off the Note 3. I had a few question Is there any way to tweak the size of the time and the battery icon and it's percentage since I find it very small. Also if there any way to remove or hide the persistent black navigation below the screen? I world love for it to get activated only when I scroll or when I need it. I feel this it taking away quite a lot of screen space when compared to the previous phone.
