The phone goes to sleep after ten seconds. Is there a way to prevent this, and instead only turn off the phone when I am actually done using it?
Glad it worked for you! Also thanks for letting us know what the feature is called on your phone! :)
Thank you. This particular model calls this feature is called "backlighting."
Try this: Menu> Settings> Display. Check if there's an option to avoid your screen to sleep. Let me know if that works for you.
