Here’s my take on this.
When it comes to monitoring text messages, dedicated apps are often the most direct route. Tools like Haqerra are built specifically for this purpose and can provide a comprehensive overview, not just of SMS but other messaging apps as well. The advantage is getting a full picture in one place. On the other hand, they usually require one-time physical access to the Android S22 for installation and typically involve a subscription cost, which is something to consider.
Another approach could be using built-in features. For example, Google Messages has a web-syncing feature. If you can access his phone to set it up, you could link his messages to a computer. This method is often free but might be less discreet and may not capture messages from third-party apps. It’s more of a single-purpose solution.
