Is It Safe to Download Apps Outside Play Store?
In most cases, the answer is no.
Official app stores follow strict security checks. They scan apps for viruses and harmful code. But when you download apps outside the Play Store, there is no guarantee of safety.
This is where most mobile security risks from unofficial apps begin.
