I have a Droid charge being sent to me to replace my disastrous thunderbolt. I'm pumped about having a stable device again but I am concerned about the lagging issues. What are some ways, tips and tricks, whatever you want to call it, ways to prevent or do away with lagging?? Non rooted by the way. I would love to root but I get very intimidated just when reading the root instructions... Anyways... TIA
