Anyone who’s used Android’s play store has seen them at some point. Applications claiming to improve battery life or “clean up your phone”, or even providing antivirus capabilities when you download them. A recent report from an Australian antivirus testing group, AV-Comparatives, found that of a pool of 250 apps tested, two thirds were ineffective in detecting malware downloaded on to a phone. Only about 10% of all apps had a significant (at or near 100%) detection rate. So, why’re there so many poor quality applications on the play store? The main reason is the relatively lax requirements from google to put an app on the store, but how can you find the right apps for you on the app store? First and foremost, look for applications that are highly rated (at least 4 stars and above) and have a large number of downloads. While this isn’t perfect on its own for learning what apps are good, it’s a start where you can look into information on it and see what people think of the app on the internet.
Antivirus and anti-malware apps aren’t the only “fake” apps on the play store though, many other applications are more or less malicious or are a front for some other aspect of the application. There are flashlight apps that are widely downloaded that operate to harvest the user’s data. An application like this should only be requesting access to your camera, as that’s what’s typically tied into using the built in flash. They could also just make your screen entirely white as well, but any of these applications that also request access to your phone, microphone, calendar, and other personal information. When downloading applications, keep an eye on what it’s asking for access to and decide for yourself if you think the application should have access to that information.
In my history of working on cellular devices, I’ve seen plenty of people come in for battery or storage issues on their phone. Sometimes, it’s a legitimate problem from prolonged use of the phone, a dying battery or a phone filled up with photos. However, I’ll always see what applications the customer has. Fairly often, I’ll see these “battery saving” apps or “phone cleaner” apps as well, and the customer complains of constantly getting ads on their phone. When these applications are removed, these problems can often disappear as well. These applications are more or less doing the opposite of what they intend to do, with the battery apps constantly running in the background and eating up more and more power, and these cleaning apps just taking up more space than they “cleaned up”. All the while, due to how these constantly running apps are working they’re taking user information and constantly showing advertisements to their user.
So, how do you as a user protect yourself? Well, first and foremost is to learn what your phone can actually do. Almost all modern phones have built in flashlight functions, on androids they’re typically found from the pull down menu where you can see your notifications. Often from these same menus you can turn on battery savers. From the settings, you can get a granular look at how much battery your phone is using and what’s taking up the most memory. Using these tips, you can help protect your own information and extend the life of your phone.
