Does your phone sometimes feel like a mysterious black box full of secrets? If so, you’re not alone. Phones these days are absolutely packed with features – so many that many of us forget about all the wonderful things that they can do just a few weeks after we buy them. 

In this post, we take a look at some of the features you’re not using on your smartphone, but should be. Check them out below: 

Measure Your Blood Alcohol Levels

Did you know that your phone can measure your blood alcohol levels? Well, by itself it can’t. But with the help of a smartphone breathalyzer device, it can. These devices hook onto your smartphone and then measure the alcohol content coming off your breath. They are a great way to check whether you are over the limit and need to call a cab to get home. 

Car Start

You can also use your smartphone to start your car, so long as you have a compatible system. This way, you can turn on the engine as you approach and then drive away immediately, without having to do any fiddling around. 

Create Text Shortcuts

Typing out entire words can be a bit of a bore. But with text shortcuts, you can avoid all of that hassle. For instance, if you want to say “thank you,” all you need to type is “T U” and the phone will do the rest. Just change the settings in your auto-correct. 

Enable Grayscale

Our phones are bright colorful objects that tempt us with beautiful apps and stunning games. And all of that is great until you want to sleep. Then it becomes a problem. 

These days, however, you can make your phone grayscale. Just go to your phone settings and then look for the relevant option in accessibility. Making your screen grayscale eliminates blue light almost entirely, helping you sleep better at night. 

Create New Codes

If you run a business, you can use your phone to create a new QR code so that people can easily link to your website offline. You simply design your codes in an app, send them to an agency to print out, and then stick them where people are most likely to see them. 

Play Live TV Shows

You don’t have to use streaming services to watch live TV on your phone. Instead, you can use screen mirroring tools. These simply reflect whatever image is on the main TV screen and cast it via your WiFi onto your phone. In other words, it doesn’t matter whether you log in or not. 

Check Alkaline Battery Charge

Your phone is able to tell you how much charge your TV remote has left. Just point the infrared beam at your phone’s rear camera and then wait to see a red flashing dot on the screen. If you can see the infrared beam flashing, then it means that your remote is working. Your phone camera can pick up infrared light, even if your eyes can’t.
