After I installed the latest update, I don’t have a button to activate water lock or my phone locator buttons.
How do I get the buttons for “water lock” and “phone locator” back to my control center?
Question marked as
The previous Control Center swipe-up has moved to a quick press and release of the flat oval side button
Use Control Center on Apple Watch - Apple Support
DO NOT hold the button, as that brings up Emergency services and the power off icon.
Control Center should then show you the iPhone ping icon (find my iPhone), Battery percentage, Flashlight, Water Lock, Airplane mode, Alarm silence, Theater mode, and all the other Control Center services.
If you are not seeing all the Control Center service icons, scroll to the end and tap "Edit" where you can add missing icons, as well as reorder the icons in a way that makes the ones you user more frequently at the top of the list.
An alternate way to get some of the Control Center services is:
"Hey Siri, find my iPhone"
"Hey Siri, Flashlight"
"Hey Siri, Battery"
"Hey Siri, Airplane mode"
Getting the press and release timing just right can be an issue. You can make it more reliable by changing:
Settings -> Accessibility -> Side Button Click Speed
“Side Button Click Speed” can adjust the press and release timing, so you get the Control Center display every time. Adjusting The "Side Button Click Speed" is also useful for Apple Pay’s double press and release. There is “Default” (sub second timing of needed), “Slow” (up to a second between press and release), and “Slowest” (up to 2 seconds between press and release). I like the “Slow” setting.
NOTE: Slow and Slowest settings do not mean you have to wait a full second or 2 seconds between press and release. It just means you do not need to be super fast.
