Why Android

Why Android phones are better than the iPhone?

 The ability to run tens of thousands of apps just like the iPhone but with choice of phone models that you can choose from, without the monopoly of one company called Apple

What is Android?

Android is an operating system based on the Linux kernel, and designed primarily for touchscreen mobile devices such as smartphones and tablet computers. Initially developed by Android, Inc., which Google backed financially and later bought in 2005

What is Android Open-source community?

Android has an active community of developers and enthusiasts who use the Android Open Source Project (AOSP) source code to develop and distribute their own modified versions of the operating system

10 reasons to say no to Iphone

1) It’s expensive: Every time Apple announces a new iPhone, there is an inevitable backlash over the exorbitant price

2) Closed approach: Since its very beginning Apple has always taken a closed approach to its software and hardware.

3)  There's no micro SD card slot : a micro SD is so much easier to use and it’s a shame Apple favors design so much more over usefulness.

4)  Most iOS innovations are Android copies:  A good example of this is the new quick settings bar. The quick settings menu is a nifty addition that offers a quick and easy way to access certain options and quickly check notifications, however it’s a feature that’s been on Android for years now and the only real difference is that you access it by swiping up from the bottom of the screen, not the top.

5) Larger, Full HD Screens: iPhone 5s offers a 4-inch display with a less-than-HD 1136 x 640 resolution, That’s great specs for two years ago!

6) Your Choice of Keyboard: Want to trace between letters, change the color of your keys or get haptic feedback as you type? How about next-word prediction? Buy an Android phone.

7)Connects with NFC : NFC lets you pair with a myriad of peripherals, including headphones, TVs and media servers, with just a single tap.  Apple doesn’t seem to care about this important standard as the iPhone 5s still doesn’t have it

8)Accesses the File System: When you plug your Android phone into a PC, it mounts like a USB Flash drive and lets you see all your files and folders. When using the device itself, a simple program like Astro File Manager allows you to browse, copy, move or delete your files and folders.

9)Universal Sharing Menu: Android has a universal sharing menu that allows you to post photos, videos or text from any app with shareable content to any social network, email client, chat client or other app that can share.
Unfortunately, iOS requires each app to have its own fixed list of share options which are enabled by the developer.  Safari and the iOS photo gallery can share with Facebook, Twitter and Flickr, but not with other services such as Google+.

10) Uses a Real USB Port:  If you have an Android phone, you can not only copy files to and from your phone over USB, but also tether it or attach a USB peripheral like a Flash drive through that port. Unfortunately, in order to make a few extra dollars off of its users, Apple uses a proprietary Lightning connector that can only be connected to a USB port with the help of an adapter cable, which is likely to end up in a landfill the next time Apple changes its standards.

11)Shows Multiple Apps Side-by-Side: The iPhone 5s’s iOS 7 operating system doesn’t provide any way to run apps side by side. Considering the way that Apple handicaps developers by sandboxing apps, it’s unlikely that anyone will be able to write a third-party utility to enable multi window.

Why you need custom ROM For your android?

You May Void Your Warranty

Custom rooting may void your warranty, b installing a custom rom on some phones can't be undone, some have custom rom install count (Galaxy S II). They may be able to tell that the phone had a custom ROM installed.

But as SpaceMoose1 says,
You dont really own a device until you void its warranty

May it have bugs, no worries the stock ROM's also.

But the community will have a quicker response to the bugs.

Be careful you may brick your device..
Most of the time you need to do a clean install. Backup all your data first.

Now What, you need it?

Here the merits..

1. Fine tuned Efficiency and Performance

most of custom ROMs faster, efficient and uses less memory.
Optimized kernel, cleaned unwanted applications.
over clocking, under volted kernels.

2. Your upgrading to a newer version, new and better look (always you needs it fresh ;-) )

3. rooting/jailbreaking you are getting all control over your device.
By rooting, you actually remove the OS limits and hence can take full advantage of your Android.

With rooted devices, you can use Apps2SD, which will copy ALL your applications to a ext2/3/4 formatted SD card.

4. Like, samsung galaxy s ii is missing native sip support, you can easily make Internet calls using SIP if u use custom built ROM.

and so on

Ubuntu is best for beginners because of it's simplicity and graphical environment.

This Gnome-based operating system that is perfect for laptops, desktops and servers. It contains all the applications you need a web browser, presentation, document and spreadsheet software, instant messaging and much more.

Why Ubuntu

Ubuntu is an entirely open source operating system built around the Linux kernel. The Ubuntu community is built around the ideals enshrined in the Ubuntu Philosophy: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customize and alter their software in whatever way they see fit. For those reasons:

  • Ubuntu will always be free of charge, and there is no extra fee for the "enterprise edition," we make our very best work available to everyone on the same Free terms.

  • Ubuntu includes the very best in translations and accessibility infrastructure that the free software community has to offer, to make Ubuntu usable for as many people as possible.

  • Ubuntu is released regularly and predictably; a new release is made every six months. You can use the current stable release or the current development release. Each release is supported for at least 18 months.

  • Ubuntu is entirely committed to the principles of open source software development; we encourage people to use open source software, improve it and pass it on.

Ubuntu Installation

Install Ubuntu without altering your current Windows

How to install Ubuntu from a CD

For a linux beginner its really easy to install your first Ubuntu. Get Ubuntu CD image by downloading from here, or request Request free CDs (Shipit). I prefer you must have the latest version of Ubuntu (Jaunty Jackalope 9.04). You can install Ubuntu straight from the CD inside Windows or by booting your computer from the bootable CD.

First you have to write the downloaded image in to a cd ROM. Nero buring rom or Roxio will do it for you. If your not aware of these programs go here to have a look at this article which tells how to burn an ISO image.

ALWAYS perform a backup before any partitioning operation. This is particularly important when moving a partition, or shrinking a partition from the left side. The left side of a partition is generally where most or all of the data resides. The right side is generally free space. But it important before performing ANY partitioning operation involving already existing partitions.

You need to create some free space in your hard disk in order to install the Ubuntu, to do so firstly check for your hard disks partitions, go to disk management.

If there is unallocated space if its enough for your new linux operating system (you need at least 5GB of free space) simply close the application.

If there is no unallocated space, you can reduce another partition to make unallocated space with free partition editing tool.

Getting started

Here I'm going to show you the necessary softwares you needed to go well with the Ubuntu, like multimedia players, instant messaging clients, web browsers etc.

1. VLC media player

The cross-platform open-source multimedia framework, player and server

VLC media player is a highly portable multimedia player and multimedia framework capable of reading most audio and video formats (MPEG-2, MPEG-4, H.264, DivX, MPEG-1, mp3, ogg, aac ...) as well as DVDs, Audio CDs VCDs, and various streaming protocols. See the full features list.
It can also be used as a media converter or a server to stream in unicast or multicast in IPv4 or IPv6 on networks.

If you like VLC, please rate it on the Freshmeat and versiontracker entries!

Here I uses terminal (command prompt in windows) for installing new programs.
To open terminal go Applications > Accessories > Terminal

From the prompt run the following command.
$ sudo apt-get update ( sudo command is to get admin (root) privileges for the user)
$ sudo apt-get install vlc vlc-plugin-esd mozilla-plugin-vlc (it will ensure installing all necessary plugins to be installed with it)

2. Pidgin Internet messenger

Buddy List

Pidgin is a chat program which lets you log in to accounts on multiple chat networks simultaneously. This means that you can be chatting with friends on MSN, talking to a friend on Google Talk, and sitting in a Yahoo chat room all at the same time.

Pidgin is compatible with the following chat networks out of the box: AIM, ICQ, Google Talk, Jabber/XMPP, MSN Messenger, Yahoo!, Bonjour, Gadu-Gadu, IRC, Novell GroupWise Messenger, QQ, Lotus Sametime, SILC, SIMPLE, MySpaceIM, and Zephyr. It can support many more with plugins.

Pidgin supports many features of these chat networks, such as file transfers, away messages, buddy icons, custom smilies, and typing notifications. Numerous plugins also extend Pidgin's functionality above and beyond the standard features.

to install pidgin type the following command on terminal

$ sudo apt-get install pidgin
To get latest version of pidgin

Ubuntu ships Pidgin but does not update it after a release (except for security issues and high-severity bugs). For those users who desire new releases of Pidgin, we have packaged Pidgin in a PPA. If you encounter problems with these packages, try building from source and report the bug.

To setup the PPA, copy-and-paste these commands into a terminal:

sudo apt-key adv --recv-keys --keyserver \ 67265eb522bdd6b1c69e66ed7fb8bee0a1f196a8

echo deb \ `lsb_release --short --codename` main | \
sudo tee /etc/apt/sources.list.d/pidgin-ppa.list

After doing this, open Update Manager, check for updates, and then install the newly available Pidgin packages.

Future Pidgin updates will show up in Update Manager along with the usual Ubuntu updates. The PPA will need to be re-setup only after upgrading Ubuntu.

This PPA is maintained by one developer, so please be patient. It often lags behind the source releases a couple of days.

Voice and video support is only built on Jaunty (9.04) and up.

3. Opera


Browse to the folder where you put the downloaded file, assumes it is at desktop

$ cd Desktop

Desktop:-$ sudo dpkg -i opera*.deb

The second method is to download Opera from the Ubuntu repositories. This is probably the more trusted method, but many users prefer first method due to the fact that it can often be more up to date. . To install Opera use the following:

$ sudo apt-get install opera
