One of the best Android phones in its day!

Phone owned for more than a year

This was one of the best Android phones I ever used back in the day. Was truly an alternative to iPhone in a lot areas. Still fell short in some though. A great classic. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Still Going Strong 6 Years On

Phone owned for more than a year

I've owned 2 of these phones since April of 2011 and I'm still not disappointed by the performance they have.

Every 2 years the battery tends to lose its ability to hold charge so that can be easily and cheaply replaced. Personally, I've upgraded the batteries to aftermarket ones that hold 3500mAh so they last much longer.

One of the devices has developed a fault in the Micro USB charging port and so the port needs to be replaced. The other device has a vibrate motor that no longer functions.

Other than those 2 faults, both devices are still very capable of running modern apps and acting as a primary device.

I couldn't give the phone high enough praise as they were only really designed to last 1-2 years anyway!

I'd recommend this device to anyone and everyone as a backup or a cheap primary device.
