Help: How does Samsung mobile phone turn off background notification push?

If Samsung mobile phone needs to shut down programs running in the background, please operate:

1. Click the nearest application button in the lower left corner of the screen-enter the task manager and end the background application (some machines: press and hold the Home button to open the task manager and end the active application).

2. Close the programs that don't need to run automatically through the intelligent manager/memory manager (note: it is recommended that instant messaging apps such as WeChat self-start be set to "On"). If the Smart Manager/Memory Manager is not found in the machine, please upgrade the phone to the latest version and try to find it.

3. After installing the third-party software, the "Application License" selection window will appear. If "Auto Run" is not required, please turn it off (this method is applicable to OS5.0 and above).
