User's Manual
Android manages and carefully guards the portion of internal storage where the system, apps, and most data
for these apps are stored, because this area may contain your private information. It’s not possible to view this
portion of internal storage when you connect your device to a computer with a USB cable. The other portion of
internal storage, where music, downloaded files (and so on) are stored, remains visible for your convenience.
Android also manages how apps use RAM. It may cache some things you’ve been using recently, for quicker
access if you need them again, but it will erase the cache if it needs the RAM for activities/processes. Your
interaction with the device, will affect the way apps use storage directly and indirectly in many ways, for
example, by:-
Installing or uninstalling apps.
Downloading files in the Browser, Gmail and other apps.
C reating files. E.g. taking pictures, text files.
Deleting downloaded files or other files you have created.
Copying files between your device and a computer/laptop.
You will very rarely need to manage the way apps use RAM, however you can monitor apps’ RAM usage and
stop them if they misbehave or cause your device to experience problems.
5.8 Secure your Tablet
Depending upon how you use your Advertising Displayer, you may want to set some form of automatic screen
lock to prevent unauthorised access.
If a screen lock has been set, the screen locks whenever your Tablet’s display goes to sleep.
To adjust your Tablet lock settings:-
1. From the ‘Home’ or ‘All Apps’ screen, touch the ‘Settings’ icon.
2. Touch Personal > Security > Screen lock.
3. Touch the type of lock you want and follow the on-screen instructions.
You can choose amongst the below lock options:-
Slide - provides no protection, but lets you get to the Home screen quickly.
Pattern – Lets you draw a simple pattern with your finger to unlock the device.
Password – requires four or more letters or numbers. This is the most secure options, providing that
you input a strong password. For the best security measures, please follow the below guidelines when
specifying your password:-
o Should be at least 8 characters long.
o Contains a mixture of numbers, letters and symbols.
o Doesn’t contain any recognisable words or phrases.
