I believe this works on Android in general, but I tried on GrapheneOS. Open the Settings app. Tap Security & Privacy > More security & privacy > App pinning. After that is enabled, if you want to pin an app, open it, swipe up into the recent-apps view, tap the icon of the app above the preview pane, and select "Pin".
The feature is buried a bit. I believe this is because it's more of a best-effort protection. The settings page itself says:
"When an app is pinned, the pinned app may open other apps and personal data may be accessible. If you want to securely share your device with someone, try using a guest user instead."
Both Apple and Android have this feature preloaded. On Apple it’s called Guided Access and is three taps of the power button if enabled. On Android I’m not sure but I do know it exists (edit: it’s called App Pinning)
On iOS you can also disable specific actions and even select areas of the screen you want to disable touchscreen usage over.
100% - I would have assumed the author would have searched first as it's trivial to find this feature if you look on Google or ask ChatGPT.
I do wonder if part of the issue though is that we have thousands of these 'great' features, so discovery is poor because people can't possibly know about them all. 'great' features lost in a sea of other 'great' features.
It should work. If you mean using Guided Access while Apple Wallet is enabled, you double click for Apple Wallet and triple click for Guided Access. If you want to use Apple Wallet while Guided Access is enabled, you have to enable the side button in Guided Access settings.
This feels like a social problem, not a technological one, and I am unconvinced that a technological solution will work here.
If the worry is that the cop you hand your phone to will take more access than you want, then attempting to limit that access is probably not going to work out the way you want.
A more effective solution would be better legal protections.
I had an Android phone circa 2018 (Samsung S8) that had this feature: it was called "App Pinning" and people could only navigate inside the pinned app until you unlocked your phone like you usually would.
Edit: I am now an iOS user since 2022, and I only learn about "Guided Access" from other comments haha
> Android and iOS should have a system-level ability to lock focus on the active application.
iOS already has this, it's called Guided Access and you can access it by triple-pressing the power button... it even lets you set up areas of the screen that can't be pressed.
"Android and iOS should have a system-level ability to lock focus on the active application. This would mean you could open a concert ticket, a photo, or your digital insurance record (which is a VERY BAD IDEA to hand to a cop without this feature), guest-lock your phone, and hand it over without any worry that someone could start opening other apps to look for things you didn't want to show them."
Samsung has had this for about ten years now. Switch to the app switch view, hold the icon at the top and pin the app. If I remember correctly, on some versions this had to be enabled once in settings.
yeah, handing your unlocked phone to a flight attendant during boarding or an immigration official while entering a country has become commonplace too.

Nice. Unfortunately, GA does not seem to work with Apple Wallet at all.

I've just tested it and it works - you have to disable touch though to get the full 'lock down to one event ticket'

Unless I'm misunderstanding, isn't that what app pinning on android is?

Well, iOS does already. „Guided Access“ is exactly what you described.
I had an Android phone circa 2018 (Samsung S8) that had this feature: it was called "App Pinning" and people could only navigate inside the pinned app until you unlocked your phone like you usually would.

I need this for when my child gets a hold of the phone.
App pinning is a thing on Android already, although I don't know how well it's supported in all the devices.
iOS has a hidden album but the UX isn't great: https://support.apple.com/en-us/104987
This is a silly article. Both Android and iOS have exactly this feature.
GrapheneOS has this.

How about a guest unlock where you can lend your phone to someone to do basic web browsing or make a call, but they can’t see any of your data.
We could call it RMS mode.
Entirely logical, but phones seem designed to be tracking/surveillance devices.

I think this already exists in iOS and is called "Guided Access"? https://support.apple.com/en-us/111795

Not just because of the privacy aspects, but what if you're already using your phone to record the interaction?
This is pretty much what app pinning already does on Android, though with caveats such as the pinned app being able to launch other apps.
