The apps in the play store are totally safe but, the apps which you sideload from websites can make you a victim of Quadroot.

Once, the app is installed, it will give access of your phone to hacker.
There are total 900 millions devices which are vulnerable to the Quadroot. But, the devices running on MediaTek chipsets and Samsung devices running on Exynos are totally safe only the devices, which are running on Qualcomm chipsets are vulnerable to Quadroot. So, be careful while downloading apps from websites. Checkpoint has released an app in play store to check that your device is safe or not named as Quadroot Scanner
