How to Close Adobe Acrobat with a Lock Icon on OnePlus
Question details
The user needs to close the Adobe Acrobat application, which is currently pinned in the recent-apps view with a lock icon on a OnePlus smartphone.
- Product
- Adobe Acrobat
- Device & OS
- Android (OnePlus 6)
- Scenario
- Attempting to clear the recent-apps screen and close all running background applications.
- Observed behavior
- Adobe Acrobat stays visible on the recent-apps screen with a small lock icon and cannot be swiped away to close, even when other apps are cleared.
Ensure your OnePlus device is unlocked and you are on the home screen before accessing the app-switching interface.
Unlock and Clear the App from the Recent-Apps View
The lock icon indicates that the app is pinned to memory by the OnePlus operating system (OxygenOS). Unlocking it will allow you to close it normally.
OnePlus devices feature an app-locking mechanism designed to prevent you from accidentally closing important background apps when you tap 'Clear All'. If Adobe Acrobat was accidentally locked, you just need to toggle the setting directly from the multitasking screen.
Swipe up from the bottom of your screen and hold briefly (if using gesture navigation), or tap the square recent-apps button on your navigation bar.
Swipe left or right through your open apps until you find the Adobe Acrobat preview card.
Tap the small lock icon located either next to the app's name or at the top corner of the preview card. The icon will change to an unlocked state or disappear entirely.
Swipe up on the Adobe Acrobat preview card to dismiss it and completely close the application.
Restart Your OnePlus Phone
Use this method if the app preview is completely frozen and the lock icon is unresponsive to your taps.
Switch to WPS Office for a Seamless Mobile Experience
If you frequently encounter freezing or memory-locking issues with heavy PDF readers, consider switching to WPS Office. It is a highly optimized, lightweight free alternative that easily handles PDFs, Word documents, Excel spreadsheets, and PowerPoint presentations without draining your Android device's resources.
- 1. Install WPS Office: Download and install WPS Office for free from the Google Play Store on your OnePlus device.
- 2. Open your documents: Launch the app and grant the necessary storage permissions to automatically scan and locate your files.
- 3. View and edit PDFs seamlessly: Tap on the 'PDF' tab to view, edit, or convert your PDF files without experiencing background app locks or lag.
Frequently Asked Questions
Why do apps get a lock icon on OnePlus phones?
OnePlus's OxygenOS includes an app-locking feature in the recent-apps menu to prevent important applications from being accidentally closed when you tap the 'Clear All' button. This ensures the app continues running in the background.
How can I intentionally lock an app in the recent-apps view?
To lock an app, open the recent-apps screen, tap the three vertical dots (or long-press the app preview depending on your OxygenOS version), and select 'Lock'. A lock icon will appear to indicate it is protected from being cleared.
Does locking an app drain my smartphone's battery?
Yes, to an extent. Keeping an app locked prevents the Android system from clearing it from the RAM. Because the app continues running in the background, it may consume more battery power over time compared to an app that is fully closed.
What should I do if my recent-apps button is unresponsive?
If your navigation buttons or swipe gestures are not responding, try restarting your phone by holding the Power button. You should also check for system updates in your device settings to resolve any underlying software bugs causing the UI to freeze.
