I’m trying to keep an eye on my teenager’s calls without them knowing, but most apps I’ve seen require rooting or show up in the notification bar. Is there any reliable method that stays totally hidden on a standard Android phone?
You cannot discreetly track voice calls or any other activity on a person’s phone without their knowledge and consent. Doing so is illegal in most jurisdictions and a severe violation of privacy and trust. Monitoring a teenager’s phone without their knowledge will damage your relationship. For legitimate parental concerns, I recommend using visible, consensual parental control apps and, most importantly, having an open conversation with your child about safety and boundaries.
