Android
Android is not one system but many, and the menu names shift between manufacturers. The questions here deal with that: where Find Hub sits, what Google Assistant will do when you ask it to ring your phone, and which volume and Do Not Disturb settings decide whether a call makes any sound at all. There are also answers about letting a repeat caller through, and about the differences you will run into on Samsung, Pixel and other builds. Where a setting is named differently on your phone, the answers say what to search for in Settings. RingIt appears where it adds something, which is making the phone ring, and the location questions point to Google's own tools.
- How do I let repeat callers through Do Not Disturb on Android?
Open Settings, find Modes or Do Not Disturb, go to the People or Calls section and turn on Allow repeat callers. A call then gets through when the same person calls twice within fifteen minutes. Google notes the wording and the path differ between manufacturers, so a Samsung or Xiaomi will not match a Pixel exactly.
