After the phone operating system changes

Every autumn the phones update. The worry is that your app silently stops. On a builder, most of that work is not yours, and it helps to know which part is.

What the vendor is for

The installed app calls functions the phone provides: maps, notifications, permissions. When a function is withdrawn or a new permission becomes mandatory, the component inside the builder has to change, and every app built with it picks up the change at the next build. You should not be reading the operating-system release notes in order to keep a simple content app alive. Ask the vendor, in writing, whether store rebuilds for system changes are included in the plan you pay for.

What remains yours

• The Apple and Google accounts, including fees and any test the store asks for before a new version.
• The words in the app. A system update does not correct last season’s hours.
• The decision to publish a new build. If you have not shipped one in a long time, ask for a rebuild before you promise that the app still matches the current phones.

The web version

The link is unaffected by the store. Keep using it as the place you correct facts the same day. The icon can follow at the next build.
