One challenge with using an old or spare phone to start earning from it is understanding the device host requirements and proper setup processes. I recently came across an owner guide that provides detailed steps on preparing a device, including factory resetting the phone, ensuring it meets performance requirements like at least 4 GB RAM and Android 12 or newer, and maintaining stable uptime. The guide also emphasizes using clean devices, not daily phones. Does anyone have experience following a similar process and how straightforward was it to meet all the device host requirements?
