Parental control on Samsung.
OneUI is more permissive than MIUI but has three specific traps. Here are the settings so Quiles enforces limits reliably.
The problem
OneUI has three behaviours worth knowing.
Apps put to sleep
Samsung puts unused apps to sleep after three days without foreground use. That disables the service enforcing Quiles' schedules if the child only opens the app drawer without launching Quiles directly.
AppCloud and accessibility services
AppCloud, Samsung's safety checker, occasionally flags accessibility services as "potentially harmful". It's noise: Quiles uses accessibility transparently to lock the screen.
Game Booster
Galaxy Game Booster suppresses foreground-service notifications during gameplay. Don't worry: schedule enforcement still runs, only the icon in the status bar disappears.
Step-by-step setup
Three settings in OneUI.
Unrestricted battery
Settings → Apps → Quiles → Battery → Unrestricted. This stops OneUI from cutting the app in the background once it has been hidden for several hours.
Exclude Quiles from sleep
Settings → Battery and device care → Background usage limits → Apps that won't be put to sleep → Add → Quiles. Without this, the app sleeps after three days and schedules stop applying until the child opens Quiles by hand.
Grant accessibility
Settings → Accessibility → Installed apps → Quiles → Enable. If AppCloud warns about a "potentially harmful app", accept the dialog. Quiles needs this permission to lock the screen during breaks.
The automatic wizard
Quiles configures OneUI without you opening Settings.
During setup, Quiles detects that the phone is a Samsung and opens the OEM autostart wizard: direct deep-links to the unrestricted-battery screen, to the deep-sleep exception adder and to the accessibility toggle. Each step is marked complete once you confirm the setting.
If AppCloud shows the "potentially harmful" warning, the wizard explains it before it appears. It is not a Quiles bug: Samsung is being cautious about any app that uses accessibility, including real screen readers and real parental-control tools.
On Galaxy tablets and phones with multiple user profiles, Quiles only controls the profile where it is installed. If you turn on a secondary profile on the child's phone, install Quiles there too or disable profile switching.
OneUI 6 and OneUI 7 reorganised a few menus. The wizard knows the difference and shows the right path based on the version installed. If a deep-link fails on a beta build, the wizard falls back to the full manual path so you are never stuck mid-setup.
About Game Booster
Not a problem. Just cosmetic.
Game Booster hides the foreground-service notification so it doesn't interfere with gameplay. The service is still running: when the schedule fires, Quiles cuts access whether the icon was visible or not. If you'd rather see the notification, open Game Booster, find Quiles in the app list and mark it as "allow notifications during gameplay".
Samsung is overall the brand with the fewest surprises in Quiles. After the three settings above, behaviour stays stable for months without touching anything. OneUI updates rarely revert these permissions.
If your child uses a Galaxy A or Galaxy S from the last five years, the guide is exactly the same. Galaxy Tab devices behave identically, but it's worth turning off fast user switching: Quiles lives in a specific account and only controls that one.
About Knox: if the child's phone ships with a pre-configured Knox enterprise profile (uncommon on consumer devices), the profile may restrict installing Quiles or enforce parallel policies. In that case, disable Knox before installing parental control, not after.
