[AC Question]

My phone is running really slow and freezing up so the only thing I could think of was to reset it to factory setting but I do not want to delete my pics and music from my phone

The main purpose of a factory reset it to delete everything you've added since the phone was new, so doing a factory reset without deleting anything is ... don't do anything.

Back up everything you need (see Backing up an Android Device), do a factory reset, then restore everything. Pictures and music are easy - just drag the folders from the phone to a PC it's plugged into. Drag them back to the phone after the reset. You will lose all your installed apps. messages, etc. Read the guide.
