Measures to handle phone eavesdropping software

Is your phone rooted and jailbroken?

Google Play Store implements policies to help users be safe, but it seems that users do not know how to protect themselves. You can easily install the application outside the store if the phone is rooted and in danger of being compromised.

Apple's iPhone security is one of the most stringent products. You can only install applications and software from Apple Store, so if you install programs other than Apple Store, you need to jailbreak. Usually when the iPhone is penetrated, you won't find it. Software like Cydia, Icy, Installer, Installous and SBSettings are some of the tools used for cracking. If you find one of these applications in your iPhone, it is very likely that your phone has been exploited. Look for it in the main screen.

Rooting Android or jailbreaking iPhone gives you some specific benefits because you can dig into the system and modify the code. However, this makes the phone more vulnerable to penetration and it is difficult to resist eavesdropping software. So do not root or jailbreak your phone to ensure your own safety.
