Short answer: A phone left running as a camera keeps running on whatever the platform has changed underneath it. Unlike a Medicare plan, nothing mails you a letter listing those changes. Once a year, stand in front of the device and check five things: whether the camera permission is still granted, whether hibernation is off for the app, the two separate security-update dates, whether the last app update left the camera running, and whether the phone still has the same address on your network. Each takes under a minute. Background Camera RemoteStream is what I build; every check below applies whichever camera app you use.

Where this idea came from

Medicare Open Enrollment runs from October 15 to December 7, and I wrote a short post about it on LinkedIn this week. The government's own review sheet, Your Yearly Medicare Review (CMS Product No. 11220, September 2026), says that if you are happy with your coverage, "you don't need to do anything (your coverage will continue automatically)."

That is accurate. A few lines earlier the same sheet says: "Your Medicare costs, benefits, and providers can change each year." And near the end: "If you keep your current coverage, any changes to benefits or costs for the new year also start on January 1."

So doing nothing is not standing still. It is accepting whatever changed. The sheet's first step is to read the plan's Annual Notice of Change letter, because that letter is the plan's own list of what is different.

A phone you set up as a camera works the same way, minus the letter. The setup continues automatically. So does every change the platform makes to it. Nothing tells you which ones apply.

The five checks

1. Is the camera permission still granted?

This is the one that fails silently. From Google's app hibernation documentation: if an app targets Android 11 or higher and nobody interacts with it for a few months, the system resets its runtime permissions. On Android 12 and higher it also stops background jobs and clears the app's cache. The documentation says plainly that running a scheduled job does not count as usage.

A camera phone's normal state is "nobody opens it", which is exactly the case the rule targets. Open Settings → Apps → [your camera app] → Permissions and confirm Camera (and Microphone, if you record audio) still say Allowed.

Full mechanism and the table of which Android versions are affected: The Camera App You Deliberately Never Open.

2. Is hibernation turned off for that app?

On the same App info screen there is a toggle, worded differently by manufacturer and version: Pause app activity if unused, Remove permissions and free up space, or similar. Turn it off for the camera app. Check it again each year, because a factory reset or a reinstall turns it back on.

3. What are the two update dates?

Settings → About phone → Android version shows two separate dates: Android security update (from the manufacturer) and Google Play system update (from Google). They stop at different times. Write both down each year. If both have stopped moving, that should change where the phone sits and what network it is on.

Which components the second line still covers, and where it ends: Your Old Camera Phone Stopped Getting Security Updates.

4. Did the last app update leave the camera running?

Installing a new version of an app ends the running one. Google's managed Play documentation says that "if the app is in use when the update is ready to install, the system will close the app to complete the process." What happens next depends on the app, not the platform.

Once a year, look at the camera app's Play Store page and decide on purpose whether Enable auto update stays on for that one app. If it stays on, check after an update that recording actually resumed. The full trade-off: The Update You Did Not Schedule.

5. Does the phone still have the same address?

If you view the camera from another device on your network, you probably saved an address for it. Routers get replaced, reset, and updated, and a phone that got a different address still records happily while your bookmark points at nothing. Open the camera's viewer from the device you normally use and confirm it loads. If your router is not yours to configure: Every Guide Says "Reserve the Address on Your Router".

Two physical checks while you are standing there

  • Look at the phone itself. A phone that has sat on a charger for a year deserves a look at the case and screen for any bulging. If the back is lifting or the screen is being pushed up, unplug it and retire it.
  • Play back one recent clip all the way through. A file that exists is not a file that plays. This is the only check that tests the whole chain.

Put it on the calendar

The Medicare sheet gives a fixed window because a review with no date does not happen. Pick a date for the camera too. The first week of a season change works, or whatever day you already change smoke-alarm batteries.

Doing nothing is a decision to accept the changes. Once a year, look at what you are accepting.
