Fixing Accessibility Service Stops Automatically (MIUI, Samsung, OnePlus, Vivo)

On many Android smartphones—particularly devices manufactured by Xiaomi (MIUI/HyperOS), Samsung, OnePlus/Oppo/Realme, and Vivo—aggressive manufacturer battery optimization algorithms automatically terminate background accessibility services after a few hours or when the phone enters standby mode. Here is how to keep Quietube running uninterrupted.

1. Xiaomi, Redmi & POCO (MIUI / HyperOS)

1. Open Settings > Apps > Manage Apps > Quietube.
2. Enable Autostart.
3. Tap Battery Saver and select No Restrictions.
4. Open your Android Recents app switcher, long-press on the Quietube card, and tap the Padlock icon to lock Quietube in memory.

2. Samsung (One UI)

1. Open Settings > Battery and device care > Battery.
2. Tap Background usage limits.
3. Tap Never sleeping apps and add Quietube to the list.
4. Under Apps > Quietube > Battery, select Unrestricted.

3. OnePlus, Oppo & Realme (OxygenOS / ColorOS / Realme UI)

1. Open Settings > Battery > More settings > App battery management.
2. Select Quietube and enable both Allow background activity and Allow auto-launch.
3. In Recents view, tap the three dots beside Quietube and choose Lock.

4. Vivo & iQOO (Funtouch OS)

1. Open Settings > Battery > Background power consumption management.

Following these steps ensures Quietube's focus blocker remains active and reliable throughout all your study sessions.
