Editor Reviews

Tested by: Priya Natarajan, Mobile Apps Editor | Test period: 17 days | Devices: OnePlus Nord 3, Pixel 8a

Cool CallScreen-Birthday Theme carries roughly 10M+ installs reported by the developer, putting it in the well-established tier inside the Productivity category. The app's strength is consistency rather than novelty. Multitasking, sync, and recovery after airplane-mode toggles all worked the way an experienced user expects.

Cold-start time felt competitive against the most-installed peers in the same category.

Cool CallScreen-Birthday Theme sits comfortably for users who have at least basic familiarity with the Productivity category. New users will benefit from the in-app onboarding; power users will want to spend time in the settings panel after first launch.

AppsSurf Verdict: a dependable pick. Not the flashiest option in Productivity, but reliable across the test window.

Editor Pros and Cons
Pros (Editor verdict)
  • Quick to install via APK and the package size stays manageable for older devices.
  • App responded predictably during multi-task switching with messaging and browser apps open.
  • Editorial testing did not surface intrusive ads inside the core experience.
  • Cloud sync (where applicable) reconnected without conflicts after airplane-mode toggles.
Cons (Editor verdict)
  • Premium tiers often gate the more advanced workflow features.
  • Some optional in-app features still rely on Google services that may not be present on every ROM.
  • Initial setup may require granting permissions some privacy-conscious users will want to review.
Common Questions about Cool CallScreen-Birthday Theme
  • 01
    Is the Cool CallScreen-Birthday Theme APK on AppsSurf safe?

    We mirror Cool CallScreen-Birthday Theme from publicly-distributed builds and verify each upload before publishing. The same package is rechecked on every version bump. If you have a sensitive device, we still recommend cross-checking with the developer's own page before installing outside the Play Store.

  • 02
    How do I install Cool CallScreen-Birthday Theme from an APK?

    Tap the download button to grab the Cool CallScreen-Birthday Theme package, allow installs from this browser when Android prompts, then open the file. The installer asks for the same permissions Google Play would request. After install, Cool CallScreen-Birthday Theme appears in your launcher like any other app.

  • 03
    Does Cool CallScreen-Birthday Theme sync data across devices?

    When the underlying account is signed in, Cool CallScreen-Birthday Theme syncs preferences and stored items across devices using the developer's cloud. We tested logout/login on two devices and the state restored cleanly within a few seconds.

  • 04
    How do I keep Cool CallScreen-Birthday Theme up to date if I install via APK?

    When Cool CallScreen-Birthday Theme ships a new version, we publish the updated package on this page. You can either revisit this URL periodically or follow the version history at the bottom of this page. APK installs do not auto-update through Google Play, so manual reinstall is the way to track or any subsequent build.

  • 05
    Is Cool CallScreen-Birthday Theme appropriate for the rating shown (Rated for 18+)?

    The developer rates Cool CallScreen-Birthday Theme as Rated for 18+. Our editors looked at the live experience and did not encounter content beyond that rating during the test window, but parental review is always a good practice for any social or open-content category.

  • 06
    How do I uninstall Cool CallScreen-Birthday Theme and clear its data?

    Long-press the Cool CallScreen-Birthday Theme icon in your launcher and pick App Info -> Uninstall, or remove it from the system Apps menu. To clear residual files, also use Storage -> Clear Storage from the same screen. AppsSurf does not retain any of your in-app account data; that lives with the developer.
