You have been using a SD card with your Wiko powered by Android™ Lollipop. Going to Android™ Marshmallow entails a few changes regarding SD card management.
A notification appears in the taskbar "New SD card detected" in the following cases:
- at the moment of Android™ Marshmallow update,
- if you insert this SD card into another Wiko powered by Android™ Marshmallow.
At the opening of this notification, the following message is displayed:
The selected option can delete your apps or make them disabled.
In order to prevent any loss of data and optimize your SD card operation, Wiko proposes the procedures below before updating or changing your smartphone.
- Option 1: "Use as portable storage"
Your apps saved on the SD card are deleted irreversibly.
Transferring the apps from the smartphone to the SD card or adding new ones is not possible anymore.
- Option 2: "Use as internal storage"
This operation merges the memory of the SD card with the smartphone (ROM).
The SD card is automatically reset:
- files and apps are deleted,
- it becomes exclusively associated with your Wiko phone.
After this operation, files and apps can be shared again between the smartphone and the SD card.
Android™ Marshmallow system manages automatically the location of files and apps according to their size (± 150 Mo) and the available memory space. However, it is possible to replace them manually.
