Google has introduced a mandatory 24-hour delay before Android users can install unverified applications on their devices.

The technology company announced the change in a post on Reddit, explaining that it is gradually rolling out new app verification mechanisms. Under the updated system, Google has effectively banned the instant installation of programs from unverified sources, requiring users to complete an extended verification process before running unknown files.
To initiate the installation of an Android Package Kit (APK) file, users must navigate to their device settings, enter developer options, and enable a setting allowing apps from unverified developers. Activating this setting starts a 24-hour countdown timer.
After the full 24 hours have elapsed, the user must return to the same developer settings page and manually confirm the installation. Users can choose to grant permission either for a limited period of seven days or on an indefinite basis. Once confirmed, the developer options setting can be turned off again.
Google clarified that the new waiting period should not affect verified applications downloaded from alternative app stores that operate alongside Google Play.
Security restrictions and developer settings
The implementation comes after Google previously announced in March that installing applications on the Android operating system would become more complicated. At the time, the corporation explained that the added restrictions were designed to protect smartphone users from malicious software and potential security threats.
Developer options on Android are an advanced set of system controls built into the operating system, primarily intended for software creators to test application behavior, inspect system logs, and modify hidden settings. By placing unverified app installations behind developer options and a mandatory delay, Google aims to prevent users from accidentally installing unauthorized programs.
Comparing Android to Apple iOS
In early August, technology publication MakeUseOf noted that Android imposes significantly fewer limitations on device owners than Apple's competing iOS platform. The publication pointed out that Android permits users to install applications from unofficial app stores and grants wide flexibility for customizing the appearance of the home screen and user interface.
Google Play is the primary official app market for Android devices, providing software distribution, automatic updates, and security scanning. While Android allows sideloading, which is the practice of installing software from third-party websites or external files, cybersecurity experts note that unverified installation packages carry higher risks of malware and security threats.
