changed icon size google now launcher.

how to changes icon size google now launcher on android 7.0 or android nougat os.
first you have to developer option on. in setting.(googling how to developer mode if you dont know)
then  go to developer option, search smallest width section. then tap the number. in my case i have 5 inch screen and the number say 360 dpi, then i changed to 480 then. the font is goin small. its ok. largest number is smaller font. tap back then search display section in setting. tap display then search font section chose largest and done .. the icon will smaller at home page .. no root needed.  add + if you happy and comment if you feel nothing, and dont comment if you dont need this information. take care. have a nice day
