Disadvantages of Samsung Galaxy S2

1
The Wi-Fi reception on Samsung Galaxy S2 is not strong. But on the similar types of smartphone that are from other brands provide better Wi-Fi reception.

Samsung Galaxy S2 comes with 1650 mAH battery. At the beginning the battery goes for long time once you full charge the battery and use for normal voice and data usage. For first 25-30 days the battery will last for one day and sometimes one and half day. But once you use it for multiple works, the battery life goes down. Many of the users have reported this problem. But you will get software in Android market that boost the battery life to some extent.

Some users also complained about call drop problem. But it sometimes happens because of poor signal also.

Disadvantages of Samsung Galaxy S5

1. Hardware of the phone is pretty ordinary and people expected to see much more (Plastic design)

2. Software is improved just a little bit, not as much as everyone expected to be (Fingerprint reader fails too much.)

3.This phone has 2.5GHz processor and 2 GB RAM, which means that there is still a high chance that performance of this device can easily lack somewhere along the way

4. Price is also a disadvantage, because this phone is pretty expensive, and it won’t be easy to afford this phone

5. Even the design of the phone is improved and enchanted just a little bit -(Duplicated software apps and features.)

Disadvantages of Samsung Galaxy S4

1
Samsung Galaxy S4 smartphone is thin and light weight but to make the phone cheaper and affordable the body of the phone has been made with plastic which does not look as good as other phones on the market. Also the phone is identical to Samsung Galaxy S3 in design.
2
The camera works well but not in low light. Also the recording capability is not that much good though it has 13 MP sensor.
3
The phone has not included FM radio which is a big negative point.

If you use Samsung Galaxy S4 smartphone for gaming, apps accessing and for internet browsing, the battery will not last for a full day also.
4
Samsung Galaxy S4 has included various odd and funky software and features. So sometimes it annoys people who look for a simplistic and one step solution service.

how to download whatsapp contacts

you can now use the WhatsApp messenger on your Mac or Windows PC provided you have the WhatsApp app running on a mobile phone that is not an iPhone. Go to web.whatsapp.com on your desktop, scan the QR code on the screen with WhatsApp on your phone and you can instantly send or receive messages to any of your WhatsApp contacts from the computer.

WhatsApp supports desktop notifications in Google Chrome so you can read your messages even if the WhatsApp web app is open in some background tab. The other benefit is that you can send pictures from your desktop or the DSLR SD card without having to transfer the bulky file to your mobile. There’s no support for sending audio or video files though. The other limitation is that your mobile phone should be connected to the Internet for you to use WhatsApp on the web.

How Airplanes Work

Human flight has become a tired fact of modern life. At any given moment, roughly 5,000 airplanes crisscross the skies above the United States alone, amounting to an estimated 64 million commercial and private takeoffs every year [source: NATCA]. Consider the rest of the world's flight activity, and the grand total is incalculable.
It is easy to take the physics of flight for granted, as well as the ways in which we exploit them to achieve flight. We often glimpse a plane in the sky with no greater understanding of the principles involved than a caveman.
How do these heavy machines take to the air? To answer that question, we have to enter the world of fluid mechanics.
Physicists classify both liquids and gases as fluids, based on how they flow. Even though air, water and pancake syrup may seem like very different substances, they all conform to the same set of mathematical relationships. In fact, basic aerodynamic tests are sometimes performed underwater. To put it simply, a salmon essentially flies through the sea, and a pelican swims through the air.
The core of the matter is this: Even a clear sky isn't empty. Our atmosphere is a massive fluid layer, and the right application of physics makes it possible for humans to traverse it.

what is i cloud computing

Cloud computing is is typically defined as a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications.
In cloud computing, the word cloud (also phrased as "the cloud") is used as a metaphor for "the Internet," so the phrase cloud computing means "a type of Internet-based computing," where different services — such as servers, storage and applications — are delivered to an organization's computers and devices through the Internet.
Cloud computing is comparable to grid computing, a type of computing where unused processing cycles of all computers in a network are harnesses to solve problems too intensive for any stand-alone machine.

what is web design

All these website elements combined together form websites. Often, the meaning of "design" is perceived solely as a visual aspect. In reality, website design includes more abstract elements such as usability, ergonomics, layout traditions, user habits, navigation logic and other things that simplify the using of websites and help to find information faster.

Sometimes the technical side of website design is emphasized in the definition of design. Surely, the modern website building involves server side scripting like php, asp and cgi, websites' visual side is defined with html and css, user experience is enhanced with dynamic javascript and ajax. When talking to people with poor technical knowledge, instead of speaking about technical details, we concentrate on functionalities, e. g. to what extent it is possible to update a website through content management system and which features are visible to users.

In classical terms, design describes the visual appearance of a website. Traditional approach involves contrast, coloring, balance, emphasis, rhythm, style of graphical elements (lines, shapes, texture, color and direction), use of icons, background textures and general atmosphere of overall website design.

All these elements are combined with the fundamental principles of design in order to create a superb result that meets the goals set for the website.

How Search Engines Work

The first basic truth you need to know to learn SEO is that search engines are not humans. While this might be obvious for everybody, the differences between how humans and search engines view web pages aren't. Unlike humans, search engines are text-driven. Although technology advances rapidly, search engines are far from intelligent creatures that can feel the beauty of a cool design or enjoy the sounds and movement in movies. Instead, search engines crawl the Web, looking at particular site items (mainly text) to get an idea what a site is about. This brief explanation is not the most precise because as we will see next, search engines perform several activities in order to deliver search results – crawling, indexing, processing, calculating relevancy, and retrieving.

First, search engines crawl the Web to see what is there. This task is performed by a piece of software, called a crawler or a spider (or Googlebot, as is the case with Google). Spiders follow links from one page to another and index everything they find on their way. Having in mind the number of pages on the Web (over 20 billion), it is impossible for a spider to visit a site daily just to see if a new page has appeared or if an existing page has been modified, sometimes crawlers may not end up visiting your site for a month or two.

What you can do is to check what a crawler sees from your site. As already mentioned, crawlers are not humans and they do not see images, Flash movies, JavaScript, frames, password-protected pages and directories, so if you have tons of these on your site, you'd better run the Spider Simulator below to see if these goodies are viewable by the spider. If they are not viewable, they will not be spidered, not indexed, not processed, etc. - in a word they will be non-existent for search engines.
