What is Device care and how do I use it?
Please note: Device care is the optimisation app for devices running Android Pie and higher. If your device is running Android Oreo or Nougat your optimisation app will be named Device maintenance and function in a similar way to Device care. If your device is running Android Marshmallow or below you can optimise performance with Smart manager
Device care gives you all the tools you need to keep your device running smoothly, automatically optimising your battery, storage, memory and security. When you open Device care, your phone will run a diagnostic check and give you a score out of 100. The higher your score is, the better optimised your device is.
Where is Device care?
By default there isn't an app icon for Device care. Instead, it can be found by going to Settings > Device care
Optimising your device
Optimising your device ensures that it is operating in top form at all times. Optimisation scans your device to determine what is using your battery, how your storage is looking, what is using the most memory and if there are any threats on your device. Optimisation happens automatically once a day but can also be started manually.
Your device is scheduled to automatically optimise itself once a day. You can customise the auto optimisation feature to adjust when it will run and whether or not it will close your background apps.
Please note: your phone will only be optimised if the screen is off and your device isn't in use. It is recommended to schedule optimisation for a time that you are not normally using your device
Please note: your most recently used apps will not be closed. Only your background apps will be closed
The battery is the beating heart of your device, giving you the power you need to use your favourite apps. When optimising the battery, Device care will close any apps that are draining your battery in the background. Through Device care you can change the power mode, check your battery usage and customise a range of power management features.
There are a number of power modes available on your device. Each mode balances the performance of your phone with the battery used, with higher performance modes using more battery than lower performance modes.
All of your apps and files are saved to the internal storage of your device unless you're using an SD card. If you find that you are running out of storage space, Device care can show you if you have any duplicate files, large files or unused files to help you free up some space.
The memory on your device quickly loads all of the information about the app or game you are using. If your device is close to using all of it's available memory you may find that your device slows down or apps don't function as they should. You can free up memory on your device by closing apps that are running in the background.
There may be some apps that you don't want to close when optimisation occurs. Any apps that you don't want to close can be added to an exemption list that won't be checked when your device is optimised.
It's important to keep your device secure from any threats to your data. Fortunately Samsung devices are full of secuirty features such as Samsung Knox. The Device care app is partnered with security experts McAfee to help scan your device for malware and suspicious activity.
