Google I/O has already begun, and as expected, they’re showcasing some of the upcoming Android phones we can look forward to at the said event. Fortunately, Phandroid took the liberty of taking some snapshots of the units being displayed there to share with the rest of the world.

Samsung Acclaim

Samsung Galaxy i5801

Next we have the Samsung i5801 which could eventually be launched as the Galaxy 3. We’ve posted about this Android 2.1 phone before, and has likewise been featured in a hands-on video already.

Samsung Galaxy i5500

Third is the Samsung Galaxy i5500. This baby also runs on Android 2.1 and boasts WiFi, 3G, GPS, and Bluetooth connectivity. As evidenced by the TIM-branding on it, this one’s definitely headed for Italy.

Acer Liquid Stream

Last, but certainly not the least, we have what appears to be the successor of the Acer Liquid e, the Liquid Stream. This new Acer handset is equipped with a 3.7-inch touchscreen, and runs on a Snapdragon processor with possibly Android 2.1 on-board as well.
