In this technically changing word...

In this very technically changing world, where every technical device be it mobile, laptop, or any gadgets. They are simply doing there best.

Why they are doing there best??? The big Master mine behind this is that they keep learning from there mistakes. They keep their things upgraded. 

There is a very best example:

In the late 90s, in the field of mobile phones, there was this very popular brand named Nokia, I guess you all have heard of the name before.

Nokia was one of the top growing brands worldwide... No other brands can beat the Nokia till then.

....Then what was the biggest mistake from Nokia...

Is was the UPGRADE..

It is said that the OS Android 1st come to offer Nokia to upgrade their Operating System as it was the leading brand, but Nokia refuse the offer and doesn't want to make any changes in their operating system.

Android was new in the market... HTC was the brand who 1st have the OS as android... And the name of the phone was Dream htc

At 1st android was not that famous.. Until then It start to upgrade its version day by day...

The first Android version android 1.0 (T-mobile G1) then comes

Lollipop.. Which hit the market

And year's after years Android do not stop upgrading their version  

It was formed then Nokia fall from the top to down most level.

You probably must have known...

Pie Till the date

Q is on the way.. It'll be soon in the market.

Hope you guys like this.. Thank you.
