7 Cool Cell Phone Features Few Know About

 The cell phone has to be one of the most important inventions of modern times. You can contact someone living in the opposite part of the world, write messages that are received instantly, and find all kinds of wonderful news and entertainment online. But, phones do so much more than perform these basic functions. Here are 7 particular special tricks your cell phone can do. These are amazing (especially the hologram, wow!)!
 
1. Make Your Phone into a Listening Device

If you want to turn your phone into a spying device or a baby monitor, then you’re in luck. After enabling the Auto-Answer function, muting the microphone, speaker, ringtone, and vibration, simply put your cell phone in your chosen location, then remove yourself to another place and call the handset (using another device or phone). It will answer automatically without making any sound! And you'll be able to hear everything. Pretty cool, huh?
2. Take Photos Underwater
Some smartphones are already waterproofed, but if it happens that yours isn’t, there is something wonderful you can do to make it so. Have a look at the above video to see how it can be done.
3. Make Sure No One Can Use Your Stolen Phone

Every phone in the world has its own 15 digit IMEI number, which you can find by opening your dialer and typing *#06# with the keypad. It's also visible in Settings > About > Device > Status. If you’ve irretrievably lost or had your phone stolen, you can contact your phone company to block your device, simply by quoting your unique number. If everyone did this, phone theft would have virtually no purpose.
4. Turn Your Phone into a Microscope
Using a lens that you can find on a normal laser pointer you can manipulate your phone to magnify up to one hundred times the normal size. This will be great for showing kids cell nuclei, for instance. What’s more, the images you record will be digital, which could never be said of the microscopes we grew up with!
 
5. Make Astonishing Holograms!
Holograms are so incredible that most of us still have a hard time believing they are even possible. But the amazing truth is that you can make them yourself, using your own cell phone. Just wow! Watch the illuminating video above.
6. Set Up the ‘Face Unlock’ Feature

People use different security measures to prevent others from using their phone. The most popular choices are a PIN, password, pattern gesture, or a very insecure finger swipe. Yet your phone can also do something incredible, which will certainly stop anyone using it. Android has a Face Unlock feature, that means only someone who looks identical to you can log into the phone. Simply go to Settings, Security, then tap Screen Lock and proceed to Face Unlock.
7. Make Your Phone Last Years Longer

The power jack at the foot of your phone collects all kinds of dust and dirt through its life, and this is one of the main causes of the device dying. Most of us think nothing of this, but if you actually clean it occasionally you’ll be able to substantially extend the phone’s lifespan, and get more value for money. Simply insert a syringe full of air into the power jack and inject the air. This will help you clear away the dust.
