If your Google TV seemed fast and smooth at first, but is getting slower the longer you own it, you're not alone. One of the most frustrating aspects of a smart TV is how great they are at first, but eventually get laggy, stutter, and run out of storage space. A quick unplugging helps for a few weeks, but then it's back to running slow. Thankfully, you just need to adjust a few settings, kill background tasks, and free up some space.
