How Can I Tell if My Android Has a Rootkit?

It’s pretty tough to accidentally root your phone. Most reasons for rooting are usually pretty innocent, like wanting custom firmware. Usually, you have to unlock the bootloader, and if you haven’t done that, the manufacturer's software is generally the only version with root access. So unless the previous owner or manufacturer left something unwanted on there, it's unlikely you’ve got a rootkit. If you've plugged your phone into a PC that got infected, that might be where the issue lies. Maybe it's a matter of compromised credentials instead. Better change your passwords and keep an eye on your accounts!

Antivirus apps on mobile devices have their limits, just like any other app from the app store. They typically just check your installed apps against known malicious software, which is not always effective. Rootkits can be tricky because many times they don’t show any symptoms at all. But if you notice odd battery drain, unusual CPU usage, or strange activities like pop-up ads or data breaches, those could be signs. Honestly, for a real root infection, flashing the ROM or even getting a new phone might be the best route. What made you think there’s a rootkit on your phone in the first place?
