Garmin Asus A50

Pretty fast GPS signal capturing

 My second smart phone, Garmin Asus A50 has probably the best GPS chip of all the smartphones out there. That's the perk from Garmin, you can say. Now that Garmin-Asus colloboration has ended and no new phones of similar hardware will be produced in the near future. So, I'm practically stuck with a low end A50, first launched on June 2010, almost 2 years ago. The hardware limits the capability to upgrade the Android OS. Hence, only up to Eclair (2.1) is supported.

If you used Garmin GPS device before, this would be familiar to you

Comes with free holder for the car as well

It's hard to call this a phone, it lags heavily sometimes. I would rather call it a GPS with phone capabilities. That's one of the reasons the phones are still in the market anyway. The built in GPS chip is that good. Not to mention that the phone comes with pre-installed Garmin app, similar to the app found in any Garmin GPS device.

The specs:
QualComm 7227 Arm 11, 600Mhz
256 MB ROM, 256 MB SDRAM
4GB Extendable Flash
Qualcomm GPSOne
(Here is why it's one of the best GPS chip on smartphone : LINK)

Easily rooted. Very hardware limited. Not much you can tweak with this one, but definitely worth keeping.
