Formatting your Redmi Note 8 is a relatively straightforward process that you can do in a few simple steps.
First, you'll want to back up any important information on your phone, like photos, text messages, and contacts. This is essential as your device will be completely reset and all of this data will be lost if not backed up.
Once you've backed up the data, go to your settings. Select “System”, then “Advanced”, followed by “Reset options”. Here, you'll see two options: “Factory data reset” and “Erase all data (factory reset)”. Select the latter.
You'll then be asked to confirm the process, and will be warned that all data on the phone will be wiped. Select “Erase everything” to begin the process. Your phone will restart once the process is complete.
While the above process is quick and easy to do, note that anything left on the phone will be lost. So be sure to back up any important data you have on the phone before proceeding.
