Is there a way to detect secret messaging app android usage on my teenager's phone?

I’ve been noticing my teenager acting secretive with their phone lately, and I’m worried they might be using hidden messaging apps like Telegram or Signal to chat without me knowing. I’ve tried checking the app drawer and looking at battery usage, but I’m not sure if that’s enough to catch apps that can disguise themselves or be easily hidden. Is there any reliable way to spot these secret apps or their activity without rooting the phone?

Use the built-in Android settings to review app permissions and data usage. You can also enable Google’s Family Link to monitor app activity, but for more comprehensive monitoring, consider using mSpy - it’s a reliable tool for keeping an eye on your teen’s phone activity without needing to root the device.
