Bootlooping, or having your phone stuck in reboot loops, isn’t an uncommon experience. And while certain phones and models are more prone to this, when you’re it with bootlooping, it can be very frustrating and a hassle if you’d have to contact the manufacturer or carrier. That’s why Google is including a feature it calls “Rescue Party” in Android 8.0 Oreo to help you get out of crash loops. Google explains the feature as: “Android 8.0 includes a feature that sends out a ‘rescue party’ when it notices core system components stuck in crash loops. Rescue Party then escalates through a series of actions to recover the device. As a last resort, Rescue Party reboots the device into recovery mode and prompts the user to perform a factory reset.”
There won’t be any activation from your end, Rescue Party will activate itself if its sees that there’s an issue. It’s turned on by default and won’t need any special hardware to work. Each rescue level it goes through will take around five minutes and Google hopes your device will self-recover instead of you needing to get in touch with the phone’s manufacturer or your carrier.
