Samsung's first Android phone was unveiled 15 years ago

Samsung i7500 Galaxy was unveiled in April 2009

The i7500 Galaxy was unveiled in April 2009 and launched in June 2009. It came six months after the world's first Android smartphone, the T-Mobile G1 (made by HTC). Unlike most other smartphones (and all other Android and iOS devices), the i7500 Galaxy had an OLED screen and a bigger battery. More importantly, it ran the stock version of Android and used a Qualcomm processor (MSM7200A), similar to many other HTC phones released around that time.

It featured a 3.2-inch OLED screen with HVGA resolution. It used a Qualcomm processor, 128MB RAM, 8GB storage, and a microSD card slot. It came with Android 1.5 pre-installed. It had a 5MP rear camera with autofocus but lacked a front-facing camera. It also had an accelerometer, compass, GPS, 3.5mm headphone jack, and a microUSB port.

In 2010, Samsung launched the legendary Galaxy S

One year later, Samsung launched the legendary i9000 Galaxy S (popularly known as Galaxy S), propelling the company to new heights. It had features that were unheard of in 2010, featuring a huge 4-inch Super AMOLED screen, Gorilla Glass protection, a 1GHz Hummingbird processor, and TouchWiz 3.0 (Samsung's first Android skin). It could also record HD videos and featured the aptX codec, DLNA, a microSD card slot, and a 1,500mAh battery.
