The Facebook app’s codename is Katana. When you install the Facebook app, it creates a folder named com.facebook.katana on your phone for saving its data files.

So, com.facebook.katana is not a virus or malware as it’s your lovely (or hated) Facebook app and is not harmful.

Just like Katana is the codename for the Facebook app, Orca is the codename of the Facebook Messenger app. If you see the com.facebook.orca folder on your smartphone, consider that to be a Facebook Messenger folder.

Fix 4: Check the Battery Saver Settings

Developers of Android and iOS make efforts to ensure that your phone doesn’t drain the battery quickly. For this, they restrict apps on the OS that are heavy and use a lot of resources. This feature can stop the functioning of some useful apps like Facebook. You may also see a notification that com.facebook.katana is causing performance issues.

To prevent or solve this issue, allow the Facebook app in the battery optimization options or disable the battery saver feature altogether. Note, by turning off the battery saver, your phone may perform better but your phone’s battery will need charging more often.
