How do I change the timer for the screen going dark on my Samsung Galaxy Ace 4?

To change the font and the font size follow these steps.

1. From the Home screen touch Apps Icon Apps.  

2. Touch Settings Icon Settings.

3. Touch Settings Display Icon Display.

 

Touch Font > Font style and choose Default, Choco Cookie, Cool Jazz, Rosemary, or Samsung Sans. Touch Download to purchase or download free fonts from Samsung Apps.

Touch Font > Font size and choose from Tiny up to Huge. The Huge font size may be used only in certain applications. In applications that cannot support the Huge font size the Large font size will be used instead.
