Storage and file management
10.1 What do I do if the internal storage is full and an error
message appears when applications are opened?
The Android operating system for mobile phones is installed on the system partition of the
phone's internal storage. When a phone doesn't have sufficient RAM available, the operating
system will allocate some storage space outside the system partition to be used as swap space.
This allows data to be freely moved in and out between the RAM and swap space. If your
phone's internal storage is full, the swap space may not be large enough to allow the data to
move in and out. In this situation, processes using large amounts of RAM may encounter
errors. To resolve this problem, delete some content from the phone's internal storage and
restart the phone.
10.2 What do I do if no notification pops up on my phone
after connecting it to a computer?
First, please check whether the mobile phone drivers are installed. If the drivers are already
installed, and no notification pops up even though the USB cable is connected, please check
whether
Allow USB debuggings

up if your phone is connected to the same computer again.
