Android continues to be the dominant smartphone OS in global smartphone sales, and over the years, Google has doubled down on health and safety features across all Android devices. From apps like Personal Safety to features such as unknown tracker alerts, there’s a wealth of safety features quietly working in the background. The problem is that not all of these features are enabled by default, as some require additional setup in order to work.If you’ve recently switched to a new Android phone or have been using one for years, it’s possible that you’ve overlooked some of these critical and highly useful features. It’s a good idea to take a moment to set these up right away for your own well-being.
