my dad and i have the exact same phone the only difference being his is black and mine is the white s5. tonight i noticed when he plugged his in a screen came up on his lock screen telling him that it was smart charging and how long it would take for his phone to be fully charged. He doesnt have an app on his phone that has that information. and when i plug in my phone I dont get the same info. How can i get that screen to pop up? I like knowing how long its going to take for my phone to charge specially when i am in a hurry. any ideas on what the app is?
