Now that the T-Mobile G1 is very old, it looks like Nokia Communicator paired with O2 XDA. But at the time, this was really a great new product on a market where Apple seemed to have it all.
When evaluating the Google Nexus One, the HTC-produced phone and integrating some of Google's modern technologies, Techradar said 'it can't be felt that there will be more from the tech giant'. .
Theoretically it is better than the iPhone but although not as smooth as the Apple phone, it still has significant improvements compared to other Android products.
Motorola Xoom was not the first Android tablet, but it was the first one to be really better, but the previous attempt was just to use the phone OS, making it bigger and hoping to be like the iPad.
Xoom is different. It runs Android 3.0 Honeycomb, also the first Android to think of tablets since design.
Tablet running Android 3.0 Honeycomb
At that time, there were few applications for tablets, causing Android tablet in general and Xoom in particular to be in trouble for some time. But it has shown the world that Android tablets are not necessarily cheap and bad. It can be a bit expensive and a bit smart.
Android 4.0, or Ice Cream Sandwich (ICS), was announced in October 2011 despite being mentioned a year earlier. Some users have to wait a long time before the producer has the supply.
This is a big problem with Android when iOS updates simultaneously on all devices and Android has to drip under each brand. Although this may be a bit embarrassing, ICS is still a revolution, not just about the interface but also messages, contacts, photos and videos.
Android has reached the 10-year-old road
It makes Android more friendly, sometimes friendly too when applications such as video players are too simple - and a very good platform for test developers.
How did we ridicule: a 5.3-inch screen smartphone is too big, and everyone knows what Steve Jobs said about the pen and touch screen 'if you see a touch pen you it was wrong. '
Note turned out to be more favorite than expected
But Samsung Galaxy Note has created a new smartphone line called phablet and many people like it. Samsung sold 1 million units in just the first 2 months.
It's still good even after upgrading Ice Cream Sandwich, causing us to raise our hands and complain that 'we're wrong, Samsung will sell a lot - for tech enthusiasts and ordinary people'.
Google made many people surprised when including Android Market, Google Music and Google eBookstore into a store, the only application called Google Play. This is intentional and also necessary when Google tries to imitate Apple, bringing all apps and entertainment to iTunes.
While Apple is determined to use iTunes as a backyard for its services, though it's not very popular, it is much more meaningful to put multiple stores together with a variety of content types about a basket. Android is therefore more user friendly.

In 2012, Google announced after 4 years, there are 300 million Android devices being activated with 850,000 times per day. Only 7 months later, the number was half a billion.
Admittedly, that number includes bad cheap low-quality phones, but there are also really impressive and competitive ones on the market. Android market share accounts for 75% of the global market, most of which are from Samsung.
The number of Android devices increased rapidly, by 9/2013, 1 billion devices were activated. But when many devices run multiple OS versions, the problem arises, such as the Stagefright hole.
Despite rapid growth, Android also faces many problems
'Obviously many manufacturers don't pay attention to updating Android . Android users deserve more than that,' Techradar wrote that day. There are holes discovered and patched years ago still exist.
Google Play Services is to fix such problems.
The Google IO 2014 event is extremely interesting, though not all inventions will pass the time challenge. Android Wear seems to no longer shine over time. Android TV makes us swear at Sony TV more than we want and Google Glass from the hero becomes zero.
But the story here is, Android is everywhere. Chromecast turned out to be a hit and Android Auto was also growing fast.
Obviously Android is not just an operating system. It is an ecosystem that includes houses, cars, technology and TVs.
Android also sold more than iOS, but in 7/2016 there was a significant change: an Android flagship, Samsung Galaxy S7 surpassed and sold more than a flagship Apple iPhone 6S.
In the US, from mid-February and May 2016, Galaxy S7 and S7 Edge also sold more than iPhone 6S and 6S Plus.
This is in part due to the moment when updating iPhone tick-tock point, 6S correction is a tock later, a slightly revised version of iPhone 6, not a new one. Many people still wait for iPhone 7, and partly because Samsung has created a good phone too.
But this also shows that Android has finally reached the level that people love and admire, instead of letting Apple dominate forever.
The battle between iOS and Android has not come to an end
In the way of Android, how far can it reach, make any other achievements or sleep on victory and be overtaken by rivals? Let's wait until Android's 20th birthday to check it out! Happy Android birthday, wish Android bigger and stronger.
