THREE USEFUL HACKS YOU SHOULD KNOW ABOUT ANDROID

Android is the most popular smartphone operating system accounting for 86% in the shares of sales in the smartphone market. As an Android user, you might want to explore the endless possibilities for getting the maximum out of your Android device. These tricks and hacks will not only make you smarter but also change the way you interact with your smartphone.


1. Use Your LED Flash And Camera For Heart Rate Monitoring

Yes, it is possible to monitor your pulse rate without the use of any fitness tracker or devices with a dedicated heart rate monitor. At once, it might seem like a gimmick or joke for you but it does actually work to a certain extent.

Now, there are many apps available which let you track your pulse rate. The ones which actually work require your finger to be placed on the LED flash after which the app uses the camera to track colour changes under your skin to monitor the amount of blood passing through.

Given that this is software dependent, don’t expect much accuracy and make sure that the LED flash on your phone doesn’t reside too far from the camera lens. Apps like Instant Heart Rate app can be used here for best results.


2. Track Your Android Smartphone

The best part with Android is that if you added a Google Account to your Android device, then Find My Device is automatically turned on. So, whenever you lose your device, just head over to android.com/find in any browser and log in with the same google account.

Now, you can see the location of your device and can further erase all the data remotely, lock it down with a message or make it ring loud (even if it’s in silent mode), provided that your lost device has access to the internet and location is on.


3. Use The Navigation-Buttons As App Shortcuts

The Button Mapper app offers the functionality to use the same buttons for triggering different applications and tasks. You can remap your keys to assign apps based on your actions like double tapping the either of home, recent and back button. I did it for deploying double tap the home button to trigger the camera app and double tap the recent buttons app to open Gmail. Moreover, you can also customize your volume and headset buttons for the same cause.
