What are some cool smartphone tricks?


What are some cool smartphone tricks?
Here are some cool smartphone tricks:

1. Detect infrared light
Our eyes can't see it, but digital cameras surely can. A smartphone's camera is indeed sensitive to IR radiation, and if you want to try it for yourself, just use a common IR remote control. The infrared beam emitted when a button is pressed will show as white or purple light in the viewfinder of your camera app. You can use this trick to check if a remote control's batteries are dead when it stops working.

2. Make money by mining Bitcoins
Yup, your smartphone can mine Bitcoin and other cryptocurrencies. You're not going to become a billionaire overnight, however. In fact, you'll probably be making a few cents per day even on a high-end phone. That's why using a smartphone for the purpose is anything by practical, not to mention that the burdening task would quickly make its internals heat up. Still, it cool knowing that a smartphone can be a Bitcoin miner, albeit a humble one.

3. Measure distances with a camera
You might be surprised to know that this actually works. Well, kind of. Distance measuring apps can't match the precision of an instrument made for the purpose, but they should prove good enough when a rough measurement is sufficient. They use trigonometry to calculate the approximate distance between the user and a visible object. To get the distance, you just have to input the height, at which you're holding the smartphone, and to aim the crosshair at the base of the object.


4. Connect to a USB stick or a mouse
Thanks to Android's USB on-the-go functionality, we can connect most common USB devices to newer Android-based smartphones and tablets. USB sticks can be hooked up for file transfers, and a connected USB mouse can be used for navigating the UI. You'll most likely need a USB on-the-go cable to pull this trick off, however, although some cool new USB drives come with both a micro- and a full-sized connector.


5. Avoid suspicious ad-supported apps
Some apps take that concept to the extreme, with ads being displayed on the notification bar. Some even add links to shady search engines to your home screen and suspicious bookmarks to the browser. These apps should be avoided since their ads consume data and battery life, not to mention that they might put your private information at risk. To see what ad-supported apps you have installed on your Android device, give Ad-Network Scanner & Detector

Hanuman travelled to Patala Loka (South America) through a Tunnel worshipped in south America

Hanuman travelled to Patala Loka (South America) through a Tunnel worshipped in south America During battle between Rama and Ravana, Mahiravana, the step-brother of Ravana kidnaps Rama and Lakshmana and takes them to Patala Loka through a tunnel. Patala Loka is described to be exactly below earth (then India) and one has to go 70000 yojanas deeper in earth to reach to reach there. Mexico and Brazil are exactly below India and one has to dig a hole(tunnel) of that distance to travel vertically. There are few such tunnels which are said to be leading to Patala Loka. The Patalkot valley in the Chhindwara district of Madhya Pradesh, India is one among them. Ravana’s son Indrajit is killed by Lakshmana, Ravana calls his brother Ahiravana for help. Ahiravana, the king of Patala, promises to help. Vibhishana somehow manages to hear about the plot and warns Rama about it. Hanuman is put on guard and told not to let anyone into the room where Rama and Lakshmana are. Ahirav...

What tricks do you know about mobiles and computers which most people are usually unaware of?

Hi, I will try to structure the answer in sections. Check if your phone supports  QuickCharge.  If it does, get a QuickCharger today!! Trust me, though the quickcharge adapter is expensive (close to INR 1100.00 for a branded Samsung charger), it is totally worth it. The time it takes to full charge your phone will be halved or even less. Use Airplane mode to charge your phone. This will ensure a marginally quicker charge. Ensure that your battery does not get very hot. The lithium-ion batteries are very bad against heat and that can quickly shorten the overall life of the battery. When not in use, try to keep the GPS on "Device Only"mode. This will also help you squeeze the last bit of juice for a longer time. Try to use only branded chargers for your phone. Charging your phone Via laptop/computer will give you slow charge speed. Your Ambient light sensor might waste more battery than it saves. This is because it constantly monitors your ambie...

Good intention but poor thinking - what troubles demonetization?

Good intention but poor thinking - what troubles demonetization? Prime Minister’s surprising demonetization experiment has rich credibility and shows his commitment towards black money fight. People have extended tremendous support as well and are ready to bear further for the success of the programme. At the same time, the programme has exposed some serious and unbelievably low quality thinking at the top level when comes to practical implementation. At the end of the first few day’s experiment, the demonetization is going on but the opposite process of monetization is facing tremendous difficulties. The inability to grasp relative importance of the most sought currencies – Rs 500 and Rs 1000 and to design and print them new in advance is a major failure. Following are some of the defects at the implementation levels. Mistake 1: Rs 2000 notes can’t fill the transaction needs of this billion plus economy along with too smaller denominations. The mistake of replacing the...
