Most Galaxy tablet problems, freezing, laggy apps, a screen that stops responding, don't need a factory reset. A restart, either a normal one or a forced one depending on what the screen is doing, often clears temporary freezing or app stuttering without touching a single photo or file (Asurion). Learning how to reboot a Samsung Galaxy tablet the right way, and recognizing the smaller set of cases where a restart genuinely isn't enough, keeps you from wiping a tablet that didn't need it.
