Various Smartphone Sensors and What Do They Do

Standard

#ACCELEROMETER

Move it in any direction and data from this sensor will spike, but leave it still and it will go flat.Apps use this data to tell if a phone is in portrait or landscape orientation, if its screen is facing up- or downward.

 
#GYROSCOPE

The gyroscope is a sensor that can provide orientation information as well,  It is also used by Google’s Sky Map for telling what constellation you’re pointing a phone at.

 
#MAGNETOMETER

The magnetometer. Yup, it is able to detect magnetic fields. The magnetometer is one of the sensors that compass applications use to point at the planet’s north pole. Apps made to detect metal use this sensor as well.

 
#PROXIMITY

The proximity sensor, which is comprised of an infrared LED and an IR light detector. It is placed near the earpiece of a phone, and for a good reason – when you place the handset up to your ear, the sensor lets the system know that you’re most probably in a call and that the screen has to be turned off. The sensor works by shining a beam of invisible to humans infrared light which is reflected from a nearby object and picked up by the IR detector.

 
#AMBIENTLIGHTSENSOR

When ambient light is plentiful, the screen’s brightness is pumped up, and when it is dark, the display is dimmed down.n fact, the Adapt Display feature uses this data to fine tune image representation.

 
#BAROMETER

Is a sensor that can measure atmospheric pressure. Data measured by it is used to determine how high the device is above sea level, which in turn results in improved GPS accuracy.

 
#THERMOMETER

The mometer for measuring ambient temperaturethey’re used to monitor the temperature inside the device and its battery. If a component is detected to be overheating, the system shuts itself down to prevent damage.

 
#HUMIDITYSENSOR

Data provided by it was used in the S Health application to tell whether or not the user was in their “Comfort Zone” – one with optimal air temperature and humidity.

 
#PEDOMETER

It is a sensor used for counting the number of steps that the user has taken. Such data is usually obtained by the device’s Accelerometer.

 
#HEARTRATEMONITOR

It is made to measure one’s pulse, and it does that by detecting the minute pulsations of the blood vessels inside one’s finger.

 
#FINGERPRINT SENSOR

Fingerprint scanners are most often used as an extra layer of security – as a substitute for a lock screen password.

 
#DETEXTEDHARMFULEDITION

The Sharp Pantone 5. Released only in Japan, it features a dedicated button which launches an app used to measure the current radiation level in the area.

What’s coming in 2016 (Smartphones)

Standard

So what’s new in 2016. As far as my experience goes, there are some companies which will be on the dead bed as Nokia was on dead bed in 2010 and finally died in 2014. There will be some companies which will make their debut and there will be some new techs.

Last year I wrote an article on this same topic which was about 64 bit processor coming on 2015 and now I am writing what’s going to come in 2016.

Please note this that I am not a professional writer.

Firstly in most of the smartphones we will see Finger Print Sensor and Force Touch. Secondly new camera technologies. There are chances this time we will find 16MP cameras instead of 13MP cameras. Thirdly many online products such as Mi, Honor, MEIZU, etc. Going to make their debut in retail stores.

Why 2015 Is Best Year For Smartphone Lovers

Standard

2015 will be a awesome year for Smartphone Users, especially for Android Users. First of all there will be 64-bit processor in every mid-range and flagships. Secondly Chinese manufacturers Xiaomi, OnePlus, Oppo, Huawei, etc. will be ruling the market, as the consumers are preferring a total value for money over brands. People wont be considering iOS & Windows most likely except for blind followers of Apple.

We all know about the 41 MP Camera sensor which made its debut few years back on Nokia 808 Pureview and on Nokia Lumia 1020, since then its out of picture, but Pureview Technology followed in many other Lumia Smartphones. But now in 2015 we will see not only Pureview but also 41 MP Sensor on Android, this time it won’t be Nokia branded nor Microsoft but coming from top Chinese manufacturer Meizu. Meizu MX5 to sport 2K Display, Nokia’s 41 MP camera, Qualcomm’s Snapdragon 810 a 64-bit processor along with Adreno 430 GPU and 4 Gigs of RAM.

Do We Really Need 64-Bit Processors For Our Android Smarthphones?

Standard

Before I start I would like you to know what 64-bit means?

Cutting long story short, YES, we indeed need an 64-bit processing power.

First of all Android versions upto Kitkat doesn’t have anything to do with 64-bit, they don’t have any support for an 64-bit architect. Secondly, there is not a single app on Google Play which is built for 64-bit. Thirdly Google with its Android Lollipop is bringing in 64-Bit support.

Basic Android phones with 1 gigs of RAM or 2 gigs of RAM has nothing to do with 64-bit. It may increase some performance, as its the latest hardware inside, but the old flagship phones like Samsung Galaxy S4, Samsung Galaxy Note 2, Sony Xperia Z1, Sony Xperia Z2, HTC One (M7), HTC Butterfly S, etc. will still be the best choice as you can have them for similar prices or even less.

EBay Has Been Hacked

Standard

Ebay’s announcement that a database holding the personal details of users – potentially all 223 million worldwide – was hacked raises a number of serious questions.

It’s the biggest reported hack ever in terms of the number of people affected, but does not affect financial data, which is stored separately.

Q: Do I need to change my eBay password?

A: Yes. eBay is recommending this to all users.

Q: But I just changed it a few weeks ago when all the Heartbleed stuff was happening. Do I really need to?

A: eBay says that it discovered the hack about two weeks ago, and that it happened between “late February and early March”. If you haven’t changed your password since then, you should.

Q: What data was stolen?

A: eBays says that the database with users’ customer names, encrypted password, email address, physical address, phone number and date of birth was breached. It hasn’t said how much of that data was copied. It’s best to assume that it all was.

Q: Who was behind it?

A: eBay hasn’t said, and it’s unlikely that any group would claim responsibility. But the fact that the hackers targeted eBay and its customer database suggests that they were commercially oriented, rather than an Anonymous-style “hacktivist” group.

Q: What could someone do with that data?

A: That varies from country to country, but enterprising villains could certainly use it for online identity theft.

Q: Was any financial data stolen?

A: eBay says not; PayPal, its payment arm, says it was not affected, and that all its information is encrypted.

Q: Should I change my PayPal password?

A: If you want to be ultra-cautious, yes, but make it different from your eBay one.

Q: What’s the biggest risk from this hack?

A: The most obvious one is “phishing” emails pretending to be from eBay asking you to reset your password, but which direct you to a fake site that will steal your password. The problem is that eBay is going to be sending out lots of emails asking people to change their password.

Normally, you can recognise a real eBay email because it contains your username in the subject line – which run-of-the-mill phishing attempts don’t have. (Those tend to say something like “eBay user, change your password!” and should always be ignored.)

But if hackers have got hold of a database with your email address and username (aka customer name), then they can format an email which will look just like the real thing – but lead you to a fake site that looks like eBay but will capture your login details.

To avoid this, don’t follow any links in emails that seem to come from eBay. Type the site’s address into your browser. Advise your friends (and relatives) about this too: if eBay’s username database has leaked to any extent, all those people are very vulnerable to phishing.

Q: Do I have to change my “secret question”, which is used if I can’t remember my password?

A: No. eBay says that this was stored separately.

Q: What method was used to encrypt the passwords, and how hard will they be to decrypt?

A: eBay hasn’t yet answered our question on this. Internet companies use increasingly sophisticated methods to encrypt passwords; the idea is that your password should be transformed in a one-way process into a string of near-random characters. When you (or someone else) enters a password for the account, it undergoes the same processing, and the resulting strings of characters are compared. If they’re the same, the password entry is accepted; if not, it’s rejected.

Q: Why did eBay wait two weeks before telling everyone of a break-in that happened in February?

A: The company hasn’t explained the timeline, but security breaches of this type typically take some time first to detect, then to determine their extent, and then to close against further hacks. It’s only then that most companies announce they’ve been affected.

Q: Will eBay be introducing two-factor authentication (where you have to enter a code from a mobile device or previously printed list in order to log in from a previously unused device)?

A: We have asked, but so far haven’t received an answer. The large email suppliers (Google, Microsoft, Yahoo, Apple) all offer “2FA” security, which ensures that even if someone steals your password they can’t log in from a new device.

Does GOD Exist?

A compelling reasons we know there is a creator of our universe is from the order within our solar system, which shows the creator is intelligent.

– Point 1: Order indicates intelligence When we observe something with order, patterns and systems our logic and experience shows there is intelligence behind it.

Example: Imagine we were walking along lost in the desert of Arabia. And then suddenly we discovered a mobile phone in the middle of the desert.

Someone them mentions to you that the way this mobile was created by chance because the desert has lots of sand which you get glass and oil where you get plastic (essential elements of a mobile).

So this mobile was a product of billions of years of random events!

The wind blew, the sun shone, the rain fell, lightning struck, the oil bubbled, the camel trod and after millions and millions of years the mobile phone formed itself.

Is there a chance that this could have randomly formed itself through natural processes?

Obviously not!

Because you understand that this mobile has order. Things are working together according to systems, patterns and processes which indicate a designer. Continue reading
