How can I use device maintenance to optimize the performance of my Galaxy S7?

Last Update Date : Apr 09. 2018

Device maintenance


The device maintenance feature provides an overview of the status of your device’s battery, storage, memory, and system security. You can also automatically optimize the device with a tap of your finger, using the quick optimization feature. This feature improves device performance through the following actions:

   • Clearing some memory.
   • Deleting unnecessary files and closing apps running in the background.
   • Managing abnormal battery usage.
   • Scanning for crashed apps and malware.

Our guide will show you how with a few taps, you can quickly improve the overall performance of your device and how you can choose a performance profile that fits best your usage (such as playing games or music).

Note: Screens and settings available may vary depending on your Canadian wireless service provider and your software version (Android Nougat, version 7, was used for this FAQ).
