Even though we designed AppBlock to be compatible with all devices, some phones might behave differently due to custom software modifications. Below, you’ll find guidance for the most common issues with specific brands and tips to resolve them. Always refer to in-app recommendations, error messages, or the Troubleshooting section for further help.
Searching for Your Device
- On a desktop, use CTRL+F (Windows) or CMD+F (Mac) to quickly locate your phone brand.
- On mobile, scroll manually to your brand or check the Help section on our website.
Note: Paths to settings or permissions may vary between models. If you can’t locate a specific option, search for your phone model and the desired setting online for more detailed instructions.
Huawei
Unfortunately, Huawei is one of the most troubled phone brands in the current market. Chinese vendors tend to ignore Android’s best practices and implement very bizarre custom modifications which make background tasks nearly impossible to run. This includes stable and reliable run of AppBlock as well.
Suggested steps:
Battery Settings:
- Phone Settings > Advanced Settings > Battery Manager > Set Power Plan to Performance.
- Phone Settings > Advanced Settings > Battery Manager > Protected apps > Mark AppBlock as Protected.
- Phone Settings > Apps > AppBlock > Battery > Enable Power-intensive prompt and Keep running after screen off.
Ignore Battery Optimizations:
- Phone Settings > Apps > Advanced (at the bottom) > Ignore optimizations > Allowed > All apps > Find AppBlock > Set to Allow.
- (For Huawei P9 Plus): Phone Settings > Apps > Settings > Special access > Ignore battery optimization > Select AppBlock.
Device Admin Mode:
- Enable AppBlock as a device administrator: AppBlock > Setting > CAPTCHA > Prevent escaping CAPTCHA. This may also prevent the system from killing AppBlock.
Note: Versions from AppGallery and Google Play may require different permissions. Review the onboarding process carefully and check the Troubleshoot section.

Xiaomi
Xiaomi might be the most troubled phone on today’s market. Chinese vendors tend to ignore Android best practices and implement very bizarre custom modifications which make background tasks nearly impossible to run.
The specific steps depend on which version of the MIUI you have.
Steps to Address Issues:
App Pinning:
If AppBlock isn’t working correctly, such as blocking features failing or Accessibility issues, try pinning it:
- Open the recent apps tray.
- Drag AppBlock downward to lock it, or tap the down arrow next to its name and select the “Lock” icon (on some devices).
- Once pinned, it won’t be removed from the background, even if you clear recent apps.
- To unpin and remove it, drag it downward again.
Battery Management:
- Settings > Advanced Settings > Battery Manager > Set Power Plan to Performance.
- Device Settings > Apps > AppBlock > Battery > Enable Power-intensive prompt and Keep running after screen off.
Additional Battery Management:
- Settings > Additional Settings > Battery & Performance > Manage apps’ battery usage > Switch Power Saving Modes to Off.
- Saving Power in the Background > Choose apps > AppBlock > Background Settings > No restrictions.
App Battery Saver:
- Go to Security > Battery > App Battery Saver > AppBlock, and set it to No restriction.
Auto-start:
- Open Security app > Permissions > Auto-start and enable Autostart for desired apps.
Device Admin Mode:
If all fails, enable AppBlock as a device administrator: AppBlock > Setting > CAPTCHA > Prevent escaping CAPTCHA. This can also help prevent the system from killing AppBlock.
Note: Avoid using Ultra Battery Saver mode on Xiaomi devices, as it stops most background apps from functioning correctly. While some models allow app exceptions, this mode may still cause minor blocking issues.

OnePlus
OnePlus devices may encounter issues with AppBlock unless specific settings are adjusted to turn off battery optimizations.
Steps to Address Issues:
Battery Optimization:
- Go to System Settings > Apps > Gear Icon > Special Access > Battery Optimization.
- Warning: Recently, OnePlus phones may randomly revert this setting from “Not optimized” back to “Optimized.” Unfortunately, there is no current workaround, so you may need to periodically check and reset this setting. A bug report has been filed with OnePlus.
App Auto-Launch:
- Some OnePlus devices include an App Auto-Launch feature that prevents apps from running in the background. Disable this feature for AppBlock.
Additional Battery Management:
- Go to Phone Settings > Battery > Battery optimization.
- Switch to the All apps list (via the top menu).
- Locate AppBlock and set it to Don’t optimize.
NOTE: Some users have reported the need to disable Doze mode in Developer Options for proper functionality.
More information: OnePlus Troubleshoot
OnePlus 5 specific settings:
- Disable Settings > Battery > Battery optimization > (three dots) > Enhanced optimization. This may also be labeled Advanced optimization on some devices.

Samsung Galaxy
Some newer Samsung Galaxy models may cause issues with AppBlock running correctly. Below are key steps to address these problems:
App Power Monitor:
Samsung’s App Power Monitor can interfere with AppBlock’s functionality. To whitelist AppBlock and prevent issues:
- Open Settings > Device Maintenance > Battery.
- At the bottom, locate the list of most frequently used apps.
- Tap on Unmonitored apps at the very bottom.
- Tap the three-dot menu to add AppBlock to the list of unmonitored apps.
Alternatively, you can disable App Power Monitor entirely to avoid these restrictions, as it has minimal impact on battery life and may hinder the phone’s normal operation.
Optimize Battery Usage:
On other Samsung devices, the steps might differ:
- Go to Settings > Applications.
- Tap the three-dot menu (top right corner) > Special Access > Optimize Battery Usage.
- Find AppBlock in the list and ensure it is not selected.
Edge Lighting:
Note: If Edge Lighting is enabled for AppBlock, it may prevent the app from waking your screen when the alarm starts. To fix this, remove AppBlock from the Edge Lighting applications list.
