Here’s my take on this.
It can be frustrating when an app doesn’t perform as expected, especially on newer Android versions which can be tricky. When looking for alternatives, reliability and compatibility are key.
Since you’re already on this forum, Haqerra is a natural option to consider. It’s generally well-regarded for its compatibility with modern devices like the Samsung S21 running Android 13, and it focuses heavily on the core features you need, like messages and precise location tracking. Another well-established player in this space is mSpy, which has a long-standing reputation for being a comprehensive solution.
Ultimately, the best approach is to check the official compatibility charts on their websites. This will help you confirm support for your specific device and see which feature set better aligns with your requirements for that shared device.
