App permissions on Android

androidtablet_June18_CMost businesses rely on tablets and their apps to help increase productivity and work output. Android tablets are one solid option with countless work apps which many people opt for. Still, without their knowledge, most tend to give permission screens no more than a cursory glance when installing apps. This can be a big mistake as checking app permissions and being aware of common permissions is vital in keeping your Android tablet safe, secure, and efficient.

Checking app permissions

Head into Settings on your Android tablet, go to Apps and then tap on any app and scroll down to the bottom of the page to see the permissions that have been granted. Note that you are not able to switch individual options on or off, so it’s all or nothing.

However, there are various third-party apps you can install to give you a better look and more control over app permissions. One of those apps is SnoopWall, which once installed will set itself as an administrator to comprehensively audit and manage the security setup on your tablet.

Common permissions 101

Modify, delete, and read storage: This gives an app permission to access the storage on your device in order to save and edit files. Most apps will require some kind of access, if only to keep temporary logs on your device. Keep in mind that any app with these permissions can also access your public folders like your photo gallery as well as your music folder.

Find and use accounts on devices: Facebook, Twitter, and Google accounts are often integral to the way you use your phone, letting you send a Tweet from anywhere and upload photos onto your Facebook account at any time. This permission simply gives an app the ability to tap straight into these accounts to make life easier for you. Bear in mind that the app can potentially access any information stored in the account in question.

Full network access: Most apps require some kind of Internet access, whether it’s for software updates, syncing, or retrieving data from online sources. Full network access is used when retrieving adverts to display, but as with most permissions, you’re relying on the app in question to use this privilege responsibly.

Phone status and identity: This permission enables apps to recognize when a call comes in and gives you the chance to answer it by pausing the current app in the background.

Prevent tablet from sleeping: When your tablet goes into sleep mode, it can interrupt certain processes such as data being written to the internal storage. This permission enables an app to keep your device awake while important system tasks are being carried out. It can also be used by video players to keep the screen on.

Read and send text messages: There are countless apps that want to replace your tablet’s SMS functionality, and this permission is used to automatically scan your incoming texts for authorization codes (used where two-step authentication is involved). This is another classic example of a permission that can be very useful or very worrying. It is vital that you make sure that the app asking for this permission has a clear use for it.

Read your contacts: While a whole range of apps ask for it, this isn’t something you want to give away without good reason. The ability to share content with your friends in some way is often the underlying purpose for this permission, but also so that the app can quickly auto-complete the names of your contacts whenever required.

Sticky broadcasts: This permission is all about the way apps communicate with each other. Android treats each app as if it were a separate user: broadcasts enable these apps to talk to one another (sometimes without your knowledge), and the stickiness controls how long they hang around in the device’s memory for. If an app wants to communicate something to other apps or to Android a long time after the event, it then uses a sticky broadcast.

There are plenty of other permissions to consider but these are the ones you’ll run into most frequently on your Android tablet. It’s important that you pay attention to app permissions in relation to new apps as well as apps you’re already using to ensure your tablet’s security.
