If you have purchased an Android device that allows you to get updates directly from Google, good. Some manufacturers are notoriously slow on updates. If you haven’t, consider doing so next time. Use passwords that are difficult to guess, and always – always – monitor what permissions you are allowing applications to possess. Finally, always know exactly where you are downloading and installing apps from – and only do so from known, trusted sites. These include Amazon, Google Play, and the phone maker’s app store.
