Introduction to Android Phones

By Karina Popa  

Android phones, also referred to as Droid phones, are mobile phones, working on an Android operating system, developed by Google. Over the years, this operating system gained popularity among manufacturers and developers as they could easily customize it to suit their respective requirements. Customizing a phone enable the providers to offer a wide range of user interfaces while using the same OS. Most of these phones, even those offered by companies using an alternate operating system, tend to have the same features which go to include the management of personal data, browsing the net, video streaming, plus a number of free as well as paid applications and software.

Technical Specifications
Android phones make use of the Android operating system, middleware and key applications. The program, written in C language, is based on a Linux kernel. The applications that a phone using an Android OS offers are basically written in Java language.

Many consider Android phones as revolutionary due to the open source configuration. Any developer, whether an amateur or a professional, can write programs for this OS, adding to the ongoing Android development by tendering the same to the Play Store from Google, a closed source application available for the users of Android phones. Consumers are then free to make use of various applications by downloading the same on their personal phone by accessing the library containing these applications.

The users of Android phones may simultaneously run a number of applications, allowing them to perform different tasks at the same time, thus offering them more flexibility of operation, compared to the competing systems. However, the hardware used in the handset plays a significant role. Certain handsets have multi-core processors, making it more convenient for users to run many operations simultaneously.

Non-Proprietary Issues
Many similar devices making use of alternate operating systems have very firm proprietary rules. For example, if you wanted to write an application for iPhone, you are not allowed to make a program which is closely similar to an application already owned and offered by Apple. All applications need Apple's approval before they get displayed at the Apple App Store. But the users of Android phones have no such restrictions. All applications in this case are developed, courtesy of Open Handset Alliance, an association that supports the development and subsequent use of openly sourced software.

Another distinctive feature of the Android system is the fact that it's not attached to any manufacturer of hardware in particular. As a manufacturer, you are free to create your own edition of the Android operating system for your phone. It enables a number of companies to use this operating system as a base, and create different versions for their specific needs, thus helping the consumer to make a selection from a wider range of options.

Different editions of Android have been exploited for producing different editions of phones. All significant improvements in this software can be identified through a code, usually based on the name of some desert. Though it is possible to update the older versions and replace those with newer editions of the operating system, this is not possible always due to the changes incorporated in the hardware of phones.

4 Of The Best Waterproof Phones

Many people are going for waterproof phones because they have the ability of withstanding water and dust. While there are many types of waterproof gadgets, not all of them are good in their working. If you are wondering which are the best gadgets to go for, here are some of them:

Xperia Z2
This phone has a rating of IPx5 and IPx8. According to Sony, the reason why the phone has two ratings is because it complies with the two waterproofing standards. The IPx5 rating means that the device has the ability of resisting water fired from a nozzle from all angles for 15 minutes.

The IP number also means that the device is protected from dust and has the ability of warding off dust particles and even if any of the particles get in, they can't interfere with the proper working of the device.

The standard IPx8 means that the device has the ability of working normally even after being left in water "continuously" at a depth of lower than one meter.

Samsung galaxy S5 Active and Sport
These two phones are also great in preventing water from getting into them. Plastic bumpers on the corners that ensure that the device is able to withstand heavy drops of water characterize the S5 Active. The S5 sport on the other hand is rubberized to prevent water and dust from getting into them.

Both devices have large buttons that make them easy to operate. According to Samsung, the phones meet military standards, which means that they can handle extremes of altitude, temperature, and humidity.

Kyocera phones
Kyocera has produced many phones such as Kyocera Hydro elite, Kyocera Hydro Xtrmh, and Kyocera Hydro life.

These devices have IP ratings of IPx5 and IPx7. The ratings mean that the devices have the ability of handling rain and water jets for long periods of time. The devices are also safe to dunk in over 3 feet of water for up to 30 minutes.

HTC one M8
It's said to have an IP rating of IPx3. This means that the device is protected against spraying water, but only at a set pressure and certain angles. This means that if the angles and pressures are exceeded, the device will start absorbing water and its functioning will be interfered with.

These are some of the best waterproof phones that you should consider buying. While the phones are waterproof, you should not handle them carelessly; you should handle them with care so that they can last for a long time.
