The non-optimized Cell Phones Market of India

Hi!! Good Morning, Good Afternoon, Good Evening

" Now a days, Cell phone Manufacturers are manufacturing phones which are more powerful than Laptops Five Years ago" , This is what we feel when you see the advertisements of the Mobile Phones released recent years. But, is it really true??

The manufacturers advertise there product on one key feature like 3 GB RAM or 64 GB Internal storage but there are not depicting there bottlenecks(performance back loggers)

Imagine if an Olympic Sprinter is told to run continuously on rock paved road without shoes, can he run has intended.
or
If a Bugatti Veyron  is fitted with fuel injection system of a Maruti Suzuki 800, can it deliver the same performance.


Imagine a Big workstation and you are working, you can use workstation only till where your hands can reach beyond that point how much ever the workstation be it no use for you. Similarly the worksation is the RAM and person performing work is Android i.e. the android can not utilize that much of RAM. why do you need it.

so, for an optimized smart phone perfect balance between Processor, ROM an RAM is necessary. Which is hard to find in newer phones which are actually degrading Smart phones actual intended Performances.

so dive in and explore and find only few optimized smart phones available. I wish I could afford them.

How to Find your Lost or Stolen Laptop, Mobile or Tablet For FREE

Now a Days, Electronic Devices like Mobiles, Laptops, etc have become like an Organ of our body, we cannot imagine a day without this devices.

What happens if you lost them, Horrible Right!!


Traditionally, if we lost a Mobile phone, we were taking IMEI number(s) to the cops and file a lost complaint, that too if we have the IMEI number.

and if your Laptop is lost, people even do not how to lodge a complaint of because people rearly note MAC ID and people rarely know that S/N no can be used to track down your Laptop.

and the cases where Devices are recovered is VERY RARE. If you have recovered your Lost Devices please feel free to comment down.

Here is a solution for saving your laptop from the Theft. This anti-theft / theft protection project is called PREY(click)

Go to the Prey Project page and click on Get started, you will be taken to the Sign up. Fill the form and get Signed up. I prefer using the Free Edition, It itself is powerful.

 After Sign up you will be taken to the tracking Wizard page. Download the prey according to your Laptop OS

after download finishes Install the file and login with registered EMail ID and password. Then your device will appear in 'Your Devices' List of the tracking wizard.

You can use 3 devices per account so i suggest to download even for your Cell phones. Enjoy the Freedom of Mobility of Mobile Devices without worries.

What is VoLTE

As we changed from 2G, 3G we gave interest only on data speed, not on The quality of Calls which is the main concern of the Mobile phone and there was no major improvements on the call quality

But in recent days, we are seeing new advancement in call quality that is VoLTE

VoLTE means Voice over LTE or Voice over Long term Evolution  means  transmiting and recieving voice on a LTE network or 4g network

What was happening before VoLTE

For example, you were subscribed to 3G network, but when you call, the call was send by using smallest bandwidth given to you by the cellular network. due to this there was call drops was more, took more time toi connect, voice lagging and quality of voice was not good

But in VoLTE what happens is, when you call somebody, The voice goes in HD quality on LTE/4G network,means connection is ultra fast because network knows it is a VoLTE call and gives preference in the network to call, due to this delay in voice is reduced and call drops will be minimum and you will be able to listen HD quality crystal clear voice

Also, when you are using 2G or 3G when you make a call the cellular data disconnects and cellular data is resumed after the call is terminated after some time. The resume time in VoLTE is very less, say Instantaneously.

Requirements to make a VoLTE call

4G phone with VoLTE 'ENABLED' MoDem and 4G service Provider at both Called Party and Calling Party

How does Metal Detector work?

Now a day, there is now one how has not seen a Metal detector, there are present in every place where ever there is a chance of crowd, they are present in all those places. Either it may be Mall, Railway Station, Temples, etc. Ever thought how they function. No Right, so this blog is for ‘You’.

Firstly, there are different types of Metal detectors, Hand-Held Device, Gate Keeping Devices, Ground searching devices.

History of Metal detectors:

The Metal detectors were introduced/invented to search antique items and gold under the ground and later used by military for searching the hidden Land mines in war prone areas.

The size of the Machine Were Big and Bulky but Powerful and Efficient in their job. Later on, they came into security purposes with light, portable but less Powerful. (To compare, the bigger ones are able to detect even a small knife and a small pin which is at 4, The bigger ones was able to detect even a small knife and a small pin which is at 4 ft. below the ground. But, the lighter ones can detect a small knife at distance of 1 ft. but not a small pin.) So let’s see How they work

Functioning Principle of a Metal Detector:

 The main principle on which the Metal detector works is Based on Maxwell’s equations. He is the one who showed, the Omni present couples (Adarsha Dampatigalu) of the world- The electricity and The Magnetism by his equations.

In this world, where ever you see Electricity you see Magnetism and where ever you see Magnetism you see Electricity. This is the principle behind Motors and Generators, where you have electricity you produced magnetism and where you have magnetism you have electricity.

Working of Metal Detector:

There are two coils present in scanning area (whatever type of detectors it may be) transmitting coil and receiving coil. The Transmitter coil has Circuitry which converts the given voltage to magnetic field and conveys; The waves take elliptical path to receiver coil because of properties of magnetism.

If any Metallic object interferes the field, the electrons of the metal object changes there spins due to influence of the magnetic field radiated by transmitter coil.

Due to spins, there is disorientation. Due to disorientation there is electricity is generated. Since electricity is produced in metal, the metal radiates its magnetic field. So extra magnetic field is produced and it is received by the receiver coil.

There will be a Controller which measures the received magnetic field and compares with the transmitted magnetic field. According to the compared field the voltage is sent to the Buzzer Which Loudens or Softens the sound based on the voltage given. Hence when the detector is close to the Metal object or the metal object is big the sound of buzzer is loud.

This is how the Metal detector work. Hope You Have Understood. Don’t forget to comment, +1, recommend and feel free to share. But don’t copy.

And the scanner you see at the exit of shopping malls are not Metal detectors they are RFID scanner, to know more about that Follow my blog.
