Specific phone brands

Huawei

Huawei is one of the most troubled phones on the market, Chinese vendors tend to ignore Android best practices and implement very bizarre custom modifications which make background task nearly impossible to run.

Please do:

• Phone settings > Advanced Settings > Battery manager > Power plan is set to Performance..
• Phone Settings > Advanced Settings > Battery Manager > Protected apps – check for AppBlock as Protected
• Phone Settings > Apps > AppBlock > Battery > Power-intensive prompt [x] and Keep running after screen off [x]
• Phone settings > Apps > ‘Advanced (At the bottom) > Ignore optimisations > Press ‘Allowed’ > All apps > Find AppBlock on the list and set to ‘Allow’
• (Huawei P9 Plus) Phone settings > Apps > Settings > Special access > Ignore battery optimisation > select allow AppBlock app.

If all fails, please try to set the app as device administrator (AppBlock > Setting > CAPTCHA > Prevent escaping CAPTCHA). This may also prevent the system from killing AppBlock.

OnePlus

The app does not usually work on OnePlus phones unless you turn off battery optimizations for AppBlock.

System Settings > Apps > Gear Icon > Special Access > Battery Optimization.

WARNING: Recently OnePlus phones started reverting this setting randomly for random apps. So you set it to be “not optimized”, and the next day it may be back to “optimized”. There is no workaround and you may have to check system settings every once in a while.
There is a bug report filed to OnePlus.

On some OnePlus phones there is also a thing called App Auto-Launch which essentially prevents apps working in the background. Please disable it for AppBlock.

Also do:

Phone settings > Battery > Battery optimization > switch to the All apps list (Top menu) > AppBlock > Don’t optimize

NOTE: Some of our users indicated that you need to disable Doze mode in Developer options.

OnePlus 5 specifically

Disable Settings > Battery > Battery optimization > (three dots) > Enhanced optimization. This option may also be called Advanced optimisation.

Samsung Galaxy

1. S8 (and apparently also some older phones) has introduced a flawed attempt at prolonging battery life called “App power monitor“. For AppBlock to work correctly, please whitelist AppBlock from App power monitor.How to do it:Open the Settings app > Device maintenance > Battery and at the bottom you’ll see a list of your most frequently used apps. You can sleep apps individually or in a group by selecting them then tapping the big SAVE POWER button. Apps that are sleeping will appear in the SLEEPING APPS list at the bottom (tap it to expand the list).Scrolling further — all the way to the very bottom — and you’ll find Unmonitored apps. These are apps that you specifically want to exclude (white list) from App power monitor. When inside the Unmonitored apps menu, you can tap the 3-dot menu to add or delete apps from the list.Rather than bothering with any of that, you can just turn off the App power monitor feature completely as it has little-to-no impact on battery life and only serves to handicap the normal functioning of your Galaxy phone. It’s excessive and in some cases downright misleading, using scare tactics to keep you reliant on Samsung’s software when other Android devices get by just fine without it.
2. On other Samsung phones, the path may look like this:
   Phone settings > Applications > select three dot menu (top right corner) > Special Access > Optimize Battery usage > Find AppBlock on the list and make sure that it is not selected.

NOTE: If you enable Edge Lighting for AppBlock, then AppBlock will not be able to wake up your screen when the alarm starts. To allow AppBlock to work as intended, please remove AppBlock from the Edge Ligthing applications list.

Xiaomi / MIUI

Xiaomi are the most troubled phones on the market. Chinese vendors tend to ignore Android best practices and implement very bizarre custom modifications which make background task nearly impossible to run.

The specific steps depend on which version of the MIUI do you have. Things to try:

• BATTERY MANAGEMENT
  Please enable:
  • Settings > Advanced Settings > Battery manager > Power plan is set to Performance
  • Device Settings > Advanced Settings > Battery Manager > Protected apps – AppBlock needs to be Protected
  • Device Settings > Apps > AppBlock > Battery > Power-intensive prompt [x] and Keep running after screen off [x]..
• BATTERY MANAGEMENT 2
  Settings > Additional Settings > Battery & Performance > Manage apps’ battery usage
  and here:
  1) Switch Power Saving Modes to Off
  2) Choose the next options: Saving Power in The Background > Choose apps > select ‘AppBlock’ > Background Settings > No restrictions
• APP BATTERY SAVER
  Security > Battery > App Battery Saver > AppBlock > No restriction
  then enable SaA to autostart in the security center
• AUTOSTART
  (according to https://in.c.mi.com/thread-253478-1-0.html):
  • Open security app > permissions > auto-start
  • Enable Autostart for desired apps.
• APP PINNING
  It really helps AppBlock if you pin AppBlock. How to do it?
  When you open recent apps tray, just drag AppBlock downwards – it will be locked. So even if you clear recent apps it will not clear from the background. Drag downwards again to clear AppBlock from the background.

If all fails, please try to set the app as device administrator (AppBlock > Setting > CAPTCHA >Prevent escaping CAPTCHA). This may also prevent the system from killing AppBlock.

Meizu

Meizu are one of the most troubled phones on the market. Chinese vendors tend to ignore Android best practices and implement very bizarre custom modifications which make background task nearly impossible to run.

Please enable:
Settings > Advanced Settings > Battery manager > Power plan is set to Performance..
Device Settings > Advanced Settings > Battery Manager > Protected apps – check for AppBlock as Protected
Device Settings > Apps > AppBlock > Battery > Power-intensive prompt [x] and Keep running after screen off [x]..

If all fails, please try to set the app as device administrator (AppBlock > Setting > CAPTCHA >Prevent escaping CAPTCHA). This may also prevent the system from killing AppBlock.

Sony

Sony Stamina Mode makes 3rd party alarms not work. There is no workaround from our side, please disable Stamina mode or whitelist our application.

Please go to your Phone settings > Battery > Three dots in the top right corner > Battery optimisation > Apps > AppBlock.

Nokia

It seems under some circumstances Nokia behaves differently from standard Android and puts our app on the list of apps with background restrictions.

Take a look in Phone settings > Apps > Battery > AppBlock
