There is a good Android 2.2MTK smartphone that I have to introduce because it looks so well manufactured~
This smartphone named Star A5000 runs on Android 2.2 with 460+280MHz MTK6515, a 3.5 inch HVGA 320*480 touch screen, dual core memory: 512 ROM and 256RAM. All apps could work fluently.
Dual card dual standby
With a standard 3.5mm earphone jack, A5000 could provide with high quality tunes for you and you can equip a HIFI earphone to enjoy your music world as you wish—the 3.5mm jack allows a wide range of choices!
The volume keys could provide easy control and the USB is also very helpful.
The back cover is made of titanium which is light and durable. At the back of the A5000, there are, as you can see in the picture, a 3.2megapixel camera, a flash light, a loudspeaker and an antenna.
The hardware of A5000 is cool: built-in hard decoding MP4 chip that could support HD videos, original YAMAHA music chip from Japan, professional Android music player that supports lyrics and album cover showing.
Photoelectric button and touch keys are very helpful on Star A5000, and it also support G-sensor which will give you a good experience!
The 1800mA battery is also very powerful. It is said that the price is very affordable, hope it is true!
