Just use it like you would a phone. Not that hard if you ask me :) The black screen at the beginning happens when it boots up. You will know the loading is complete when the boot animation starts. Yes, it actually needs to load something, so give it a second or two. *NOTE: When you are using the calculator, please wait about half a second in between button presses. I'm working on speed improvements. PROCEDURE FOR ADDING APPS: - remix the project, add your app, and comment saying that you have added it - next, I will review your app, and put it in the play store for people to download - Once I reply saying that I have it, you can delete your remix if you want. - You will be honored for your contribution! - Also, if you want an app added, request it in the comments section and I will add it if I can. CRITERIA: - Must use some of the variables that I have already created, to make it easier for me to integrate it - Try to get a nice material-designy look to a least your icon, just like Google would want
