SkieHow do I lock a tablet so customers in a shop can only use one app?
Put the tablet in kiosk mode or give it a one-app allow list, hide the Play Store, and block settings changes. Skie then shows only your catalogue, feedback or ordering app, customers cannot browse the web or install anything, and the tablet cannot be reset from Settings. Full-screen kiosk mode is available.
A shop tablet has two problems. Customers will wander out of your app, and staff will not have time to babysit it. The fix is to make the tablet unable to do anything except the one job.
In Skie you create a group for shop tablets, attach an app list with only your app, and either use full-screen kiosk mode or the one-app list. Hide the Play Store so nobody installs anything. Leave the browser off. Optional switches let you disable the camera, screenshots, Bluetooth, NFC and outgoing calls if the tablet does not need them.
Hardening stops the usual tricks. Factory reset from Settings is blocked, safe mode is blocked, developer options and adb are blocked, adding another user is blocked, and the Skie app cannot be uninstalled or force stopped. If someone does reset it from the recovery menu, Android's Factory Reset Protection asks for the Skie organisation's Google sign-in, so a wiped tablet is of no use to whoever took it.
Tablets can be wired to a charger and left on a stand, which is where the location feature helps: geofences tell you if one leaves the shop. Lost mode locks the tablet, shows a contact message and gives you a trail.
A practical tip: run the tablet on shop Wi-Fi for a week with a staff member watching before you leave it in the open. You will find the one extra app, such as a PDF viewer, that you forgot to allow.
