Here are some tips to help you make the most of your smart device and apps and how to use them with confidence.
Install apps from recognised app stores
It is possible for some apps to exploit your mobile device once installed. This possibility increases if you install an app from a less reputable (or unknown) source. For example, someone could take a popular paid-for app, add their own illegitimate elements and then offer it for free on ‘bulletin boards’ or ‘peer-to-peer’ networks. Once the rogue app has been installed to your phone, the hacker could potentially take control of the handset, make calls, incur charges via premium SMS without your permission, or send and intercept SMS and voicemail messages. You may not be aware anything is wrong until it’s too late.
So, avoid apps from unauthorised sources, such as ‘bulletin boards’ or ‘peer-to-peer’ networks. Instead, download your apps from official stores. Above all, exercise caution – research the app and check reviews before downloading it.
Consider content ratings
Apps in some popular app stores provide content ratings. The ratings may help you judge whether an app is appropriate for children.
Typically, the ratings will give guidance on the content and intensity of themes such as violence, offensive language, sexual content, or drug references. You should be aware that each app store has its own content rating policy. This means that ratings will differ from app store to app store.
Please note these ratings relate to the content in the app itself. If you use apps that allow you or your child to connect to the internet and access content outside the app, you may want to consider further device-level or network-level protections, filters or safe search options.

Be aware of what permissions you are granting
When you download an app, it will often ask whether it can access certain systems or data on your device. This is known as a ‘permission request’ or a ‘permission’. For example, navigation apps may ask for permission to use your “current location” in order to provide accurate directions and location information. Photo editing apps may ask to gain access to your photos so that you can edit photos you take on your handset through the app.
It is generally agreed that developers should only request data and features directly necessary for the app to run. Some apps, however, may request additional permissions beyond what is strictly necessary for the particular app being accessed to function.
In order to protect your personal information, carefully read permission requests upon download or when prompted and ensure you are comfortable with the information you are authorising the app to use.
If you are not comfortable with the requested permissions, you should deny the request or search for an alternative app.
Treat your phone as your wallet
Using a smartphone to manage your money is growing in popularity. There are some clear advantages to mobile banking: apps offer a simpler and more convenient way to bank on the move, and also save you time and money. But, inevitably, there are risks too, including the fact that you store sensitive information on your mobile device that could be of use to a fraudster. Therefore, you need to remember some basic good habits, for example it’s important to log out of banking apps; download only from official app stores; not to change the factory security settings on your phone; and password-protect your phone.
Be aware of costs, especially for roaming and in-app purchases
Apps typically consume data which may use up more of your mobile data allowance. If you’re not careful about monitoring your data usage, you could end up going over your inclusive data allowance and incurring extra charges. Most mobile providers now offer online monitoring tools or apps to allow you to check your usage easily. In addition, using apps abroad can lead to higher bills. Consider switching off mobile data roaming while you are away to help avoid a bill shock. Ofcom is the UK’s communications regulator, check out their video guides which show you how to do this on some popular handsets. For further details on how to use apps abroad safely see Ofcom’s guide to mobile roaming. Many apps, both free and paid for, offer optional extras at a cost. These are known as in-app purchases. For example, you may have to make an in-app purchase to continue to play a game after a certain level, or to speed up gameplay. In-app purchasing can be of particular concern to parents because children using the mobile device may run up high charges on an account without their parents’ knowledge. Those wanting to control unwanted in-app purchasing can do so using a number of tools that are available across the recognised app stores. For instance, some operating systems allow you to require a passcode for each download or purchase.
Some mobile handsets allow you to disable in-app purchases altogether. Ofcom’s video guides show you how to do this. The screenshots are indicative as the settings may vary depending on the handset and version of the OS they have installed.
Regularly clear out the apps you don’t use
How many apps have you got on your device – and how many of these do you actually use? Typically, almost half of apps downloaded are not regularly used. Filling your device with dozens of redundant apps can affect its performance. Not only do they take up space, but some apps constantly run in the background which can slow down your device and drain your battery. Go through your apps and remove any that you don’t use anymore. For apps that you regularly use, consider keeping them up to date as this may fix app performance or security issues.
‘Clean’ your phone
If you decide to donate, resell or recycle an old mobile phone or tablet, make sure you erase all data and apps first as otherwise these may be accessed by whoever your device is passed to. You should also be able to find a ‘factory reset’ option in your device settings although this option may not delete all your personal information from the devices.
