You could improve phone performance improvement by 15% if you uninstall Facebook. No, Virginia, you don't have to cancel your Facebook account. You can still keep up with the quilting bee participants, and you can still look at photos of your "friends" food. But, you don't need an oversized app on your phone to access Facebook. Crank up your browser, and go to the Facebook page, just like you do on your notebook or desktop computer. You'll be glad you did. It will be like taking a huge monkey off your back.
