My phone is hacked

Isagi Yoichi, I removed your "answer" that you had marked as accepted. When you do that, people who are looking for questions to answer will assume you've already found a solution to your problem; that's what marking it as "accepted" means. So they'll pass by your question without trying to help if they think you already fixed it.

Can you please elaborate on the issue you're having with your phone? Saying your phone has been hacked generally means an outside person has gained unauthorized access to your phone, which is wildly different from saying there's dust in your front camera. Please clarify your question.
