Security Risks: Android 7, released in 2016, no longer receives official security updates from Google. This leaves these phones susceptible to known vulnerabilities that malicious actors can exploit.

This lack of support means users are essentially navigating a minefield of potential threats.
App Incompatibility: Many modern applications are designed to work with the latest Android versions, often dropping support for older ones. This means Android 7 users may find their favorite apps either non-functional or severely limited in features.
Performance Issues: The hardware in these older phones, while once cutting-edge, struggles to keep pace with the demands of today’s resource-intensive apps and operating systems. Lag, slow loading times, and frequent crashes are common complaints.
Battery Drain: The efficiency of older batteries degrades over time, compounded by the demands of modern software. This leads to significantly shorter battery life, making the phones less practical for daily use.
Limited Features: Android 7 lacks many of the features that users now consider standard, such as advanced privacy controls, gesture navigation, and support for the latest hardware accessories.

Modern-Day Uses for Older Phones

Despite these challenges, Android 7 phones still hold a place in the tech ecosystem. They are often repurposed in ways that leverage their existing functionality.

Secondary Devices: Many users employ older phones as secondary devices. They might use them for listening to music, playing games, or as dedicated e-readers, freeing up their primary phone for more demanding tasks.
Wi-Fi-Only Devices: With Wi-Fi access, these phones can be used for browsing the internet, accessing social media, and staying connected to the world, even without a cellular plan.
Smart Home Control: Android 7 phones can be configured as control panels for smart home devices, allowing users to manage lighting, thermostats, and other connected appliances.
Dashcams or Security Cameras: By utilizing apps and mounting accessories, these phones can serve as dashcams in vehicles or as security cameras in homes, providing a cost-effective solution for surveillance.
Educational Tools: In some educational settings, older phones can be used as learning tools for children, providing access to educational apps and resources without the expense of newer devices.
