Alright, I've had my Droid since launch. For about a month now, I've noticed that it has been sluggish and lags with certain apps or things I'm doing on the phone. Many times it also freezes on me. Knowing that this has happened since recently, I'm thinking i have a rogue app that is causing these issues. should I run a factory data reset? will that fix the problem? also, will the FDR erase all my contacts? thanks for the help!
