Keep Select to Speak Reading in the Background
When Select to Speak stops reading aloud the moment you switch to another app, the voice output is tied to whatever text is still visible on screen. Long articles or documents get cut off mid-sentence once you open a different app or lock the display. The experimental Read in background option lets narration continue independently of what is currently shown.
Uninstall an App via Settings
Long-pressing an app icon on your Oppo home screen and tapping Uninstall does not always work, especially if the shortcut sits inside a folder or has been removed from the home screen entirely. In that case the quick gesture method fails and you need a menu that lists every installed app regardless of where its icon lives. The App management section in Settings covers exactly that gap.
Remove an App Shortcut from the Home Screen
If a shortcut icon refuses to disappear when you try to clean up your Oppo home screen, the App Drawer setting is usually the reason. With App Drawer enabled, removing a shortcut only deletes the icon, not the app. Without it, home screen icons and installed apps are the same thing, so removing one uninstalls the other.
Change Home Screen Wallpaper
Tapping and holding the home screen only pulls up a handful of preset wallpapers on Coloros, so live wallpapers and your own photos are easy to miss. This happens because the quick wallpaper shortcut hides the full Wallpapers settings section, leaving many users thinking custom or animated backgrounds are not supported at all.
Install an App from the Google Play Store
If the Install button in the Play Store stays grey or the app never shows up in your search, a missing Google Account is usually the reason. Sideloaded APKs from unknown sources work differently and skip the official verification that the Play Store relies on. Once you know where the search and install controls sit on ColorOS, the process only takes a few taps.
Auto-Hide Virtual Navigation Buttons
When you open a game or video player on your Oppo phone, the navigation bar stays fixed along the bottom edge and eats into the display. This happens because the option that lets you hide the on-screen buttons is switched off by default. Until it is turned on, the bar only ever disappears if the app itself forces full-screen mode.
Allow Display Over Other Apps
When Messenger, Facebook chat heads or a call app refuse to pop up on top of other apps, the floating windows permission on your Oppo phone is usually switched off. Without this permission the app can only run in the foreground and loses its quick-access overlay. This affects chat bubbles, screen recorders and any tool that needs to draw over your current screen.
Reset App Preferences
If deleting a single app does not free up storage or clear leftover permission conflicts, a full factory reset feels excessive for what is really an app problem. Oppo's Coloros lets you reset only the downloaded apps and their data, leaving pre-installed apps like Gallery, Camera, and Calendar untouched. This option sits right next to the factory reset in the settings menu, so it is easy to trigger the wrong one by mistake.
