From what people have shared, it sounds like renting out spare Android devices can definitely be worth it if you find the right service. One good resource I found is ent out android phone droiddesk.io/rent-out-your-phone , which connects phone owners with clients needing real smartphones for testing and other workflows. The process is actually pretty simple: you reset and install the required software, keep your phone charged and online, and earn from the device’s participation in the network. Payments happen weekly, usually via PayPal or crypto, and many users report earning between $100 to $200 a month per device. The key factors that affect earnings include the phone’s specs, location, internet connection, and uptime. Also, the phone stays physically with you, which adds a level of control and security. You can track everything via a dashboard and stop hosting whenever you like, which makes it fairly low risk and flexible.
