How to optimise the performance of a Galaxy smartphone
Please note: The steps may vary slightly depending on the version of Android your device is running. Device care is the optimisation app for devices running Android 9.0 (Pie) and higher. If your device is running Android 8.0 (Oreo) or Android 7.0 (Nougat) the optimisation app is called "Device maintenance". On devices running Android 6.0 (Marshmallow) or below, optimise your device's performance via "Smart Manager".
