I would definately reset. Sounds fishy to me. Trust your gut.....

And if it were me, I'd confront him. I'd say, "what did you do to my phone? Now it's acting sluggish". Check his reaction (does he avoid your look?). If he did something, he'd know you're on to him & maybe that would prevent him from doing something (like stealing your info). Hope you don't have passwords & credit type of info on there. If you do, you need to do something about it.
