Your device should feel faster and calmer after a cleanup. The next step is to keep protections active so the junk does not come back. A few habits plus an always-on shield go a long way.
Stay clean checklist
Keep auto updates on, check storage monthly, and avoid sideloading unknown APKs. If a site or link looks odd, let your security app filter it first. Most problems are blocked right at the browser level.
If you notice sudden popups, battery drain, or a hot phone, run a quick scan and review recent installs. Catching issues early makes the fix simple.
