Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Device — smart DISPLAY with camera: A larger smart display with a touchscreen, speaker and a built-in CAMERA (for video calls, Face Match, and home monitoring) — powered by Google Assistant. Mains powered. So its symptoms are display/assistant/camera and Wi-Fi, not a phone's.
Camera & privacy: The camera enables Google Duo/Meet calls and can act as a Nest camera for home monitoring; a physical switch disables the camera and mic — if the camera 'doesn't work', check that switch is not off. Home monitoring history needs Nest Aware.
Assistant & platform: Runs on Google Assistant via the Google Home app; note Google has been transitioning some Assistant features to Gemini, and older Nest displays' feature set can change with updates.
Power path: Mains adapter into a standard outlet. Switched outlets and outlets on a circuit that trips are the two failure modes that present as device faults. Use the supplied adapter — third-party adapters that supply the right voltage at the wrong current are a common cause of intermittent restarts.
Wi-Fi: Joins on 2.4 GHz. A phone on 5 GHz cannot hand credentials to it reliably during setup, and a router that steers clients between bands under one network name will produce intermittent joins that look like a hardware fault.
Microphone: Carries a microphone with a hardware mute. A muted microphone is a physical switch state that no app setting overrides, and is the first thing to check for any voice or audio symptom.

Exact questions

Questions that only have an answer for the Nest Hub Max

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

The camera on my Nest Hub Max isn't working.+

First check the physical camera/mic switch on the back or top — sliding it off disables the camera and microphone for privacy, and this is the most common reason the camera appears dead (the screen usually shows a camera-off indicator). Slide it back on. Then confirm the Hub Max is on Wi-Fi and updated in the Google Home app, and that permissions for video calls/home monitoring are set. Home-monitoring recording history requires Nest Aware; live view and calls do not.

Structured depth, not empty permutations
