Google warns users to ditch sideloading for better security

In June 2025, Google released Android 16 for supported Pixel phones, which enhanced security features and introduced an important setting called Advanced Protection Mode. This upgrade notably anticipates and responds to the security risks associated with sideloading apps—installing apps from unofficial sources—which has been a usual practice among many Android users. The Advanced Protection Mode blocks all sideloading attempts, allowing only downloads from pre-loaded app stores such as the Play Store and Samsung's store. This measure aims to protect users from harmful applications, scam calls, unsafe websites, and other potential online threats, which had been rampant due to unfiltered third-party app installations. Google's decision is in contrast to Apple's Lockdown Mode, which caters to a limited number of individuals facing targeted advanced threats. The tech giant emphasizes the importance of adhering to security practices even before upgrading to the new Android version by discouraging the installation of any applications from non-official stores. This step is critical, as it seeks to mitigate vulnerabilities faced by users who may be lured into downloading risky apps, thus putting their devices and personal information at significant risk. Despite backlash from some Android fans who appreciate the flexibility that sideloading offers, Google’s warnings highlight a necessary shift in security practices for the majority of users, urging them to prioritize their safety over convenience.
