Is there a good Android app that blocks intrusive ads and cleans the phone in the background?

Open Browser is a mobile web browser that places a strong emphasis on security and system maintenance. For users frustrated by invasive pop-ups and malvertising, the app includes built-in ad-blocking tools designed to filter out scam advertisements and prevent unwanted redirects. A key feature highlighted in user feedback is its ability to perform cleaning and optimization tasks in the background. This means the app can clear cache or junk files while the user is occupied with other activities, which reportedly helps the phone operate more smoothly. The persistent operation without closing itself is a noted strength, providing a consistent browsing experience. However, the app’s exact methods for 'protecting against hackers' are not explicitly detailed within the app description, which may leave some security-conscious users seeking more transparency. Reviews indicate satisfaction with the perceived increase in device speed and the reduction of disruptive ads. It serves as a straightforward option for those seeking a browser that doubles as a light maintenance tool, though its effectiveness compared to dedicated security suites may vary.
