Is your ONN streaming device running slow, lagging, or freezing during playback? You’re not alone. Many users experience performance drops because of unnecessary background tasks eating up memory and resources. The good news? You can permanently shut down those processes and reclaim smooth, fast streaming.
In this comprehensive guide, we’ll discuss step-by-step instructions to disable background clutter, optimize performance, and enjoy a cleaner streaming experience.
Why Background Processes Slow Down Your ONN Device

Before we jump into the fix, it’s important to understand what’s causing Onn to lag or become slow.
• Cached Activities: Apps often keep their data in memory so they can reload quickly. But this eats up RAM.
• Background Services: Notifications, updates, and sync tasks run silently in the background.
• Limited Hardware: ONN devices are affordable, but they don’t have the same processing power or memory as premium streaming boxes.
Over time, your device feels sluggish, apps crash, and playback becomes frustrating. By disabling these processes, you’re essentially telling the device that your focus is what you are using at the moment.
Kill Background Processes Permanently
Follow these steps to permanently kill the background processes on an Onn device.
- Start by opening the Settings menu on your ONN streaming device. This is the control hub where you’ll find all system options.
- Go to All Settings.
- Scroll down and select System.
- Enable Developer Options.
- To access advanced controls, you’ll need to unlock Developer Options.
- Select About under the System menu.
- Scroll down to Android TV OS Build.

- Tap on it seven consecutive times.
After the seventh tap, you’ll see a message: “You are now a developer.” Congratulations—you’ve unlocked hidden settings that allow deeper customization. - Now, Access Developer Options. Go back to the System Menu.

- Scroll down and select Developer Options.
- This section contains powerful tweaks that can change how your device handles apps and processes.
- Toggle “Don’t Keep Activities”. One of the most effective settings here is Don’t Keep Activities.
- Scroll down until you find Don’t Keep Activities. Toggle it ON.

What does this do?
Normally, when you exit an app, the system keeps it in memory for faster reload.
With this option enabled, the system kills the app immediately after you leave it.
This means no cached data or memory hogging. Every time you open an app, it loads fresh. While this may slightly delay app launches, it ensures your device isn’t weighed down by unused processes.
Next, let’s deal with background processes directly.
- In Developer Options, find Background Process Limit.
- Select No Background Processes.

This setting prevents any apps from running in the background. The benefits are huge:
Improved Performance: No hidden tasks draining CPU or RAM.
Better Battery Life: If you’re using a portable ONN device, this helps conserve power.
Cleaner Experience: Apps only run when you open them.
Notifications may be delayed or disabled since apps can’t run in the background. If you rely heavily on instant alerts, keep this in mind.
Benefits of Killing Background Processes
Once you’ve applied these settings, you’ll notice immediate improvements:
• Faster App Launches: Apps load fresh without competing for memory.
• Smoother Playback: Reduced lag, crashes and stuttering during streaming.
• Stable Performance: Less chance of apps freezing or having network issues.
• Extended Device Life: Lower strain on hardware means your ONN device stays reliable longer.
Potential Drawbacks And How to Handle Them
No tweak is perfect, and it’s important to know the trade-offs:
• Delayed Notifications: Messaging apps or updates may not alert you instantly.
• Fresh Reloads: Apps won’t resume where you left off; they’ll restart from scratch.
• Extra Loading Time: Since cached data isn’t stored, apps may take a second longer to open.
If you find these drawbacks too inconvenient, you can always revisit Developer Options and adjust the settings. For example, instead of “No Background Processes,” you can set a limit of 1 or 2 processes.
Wrapping Up
And there you have it—your ONN streaming device is now free from unnecessary background clutter. By enabling Developer Options, toggling “Don’t Keep Activities,” and setting the Background Process Limit to zero, you’ve taken control of your device’s performance.
