Always On Display - Like Galaxy S9, LG G7 description

##Warning
I always try to improve battery runtime but it is not easy.
None-AOD supported devices before Galaxy S7or LG G5 like Galaxy S6 or LG G4, they doesn't have Low-Power-Display so battery might be used more fast then before not using AOD with apps such like this app.

This App was made by Korean High School Student.
My hobby is developing apps not my job.
I can not develop app during School Test Term.
Thank you for using.
