I've had a ZTE headset for a year now. I can clearly say that despite of it being a basic Android phone, it is by far better then any of the LG/Samsung/Sony Ericsson/ect. phones that are at the same price range.
One of my family members has a Samsung Galaxy Gio, I have the ZTE Avail.
Both phones have the same CPU and the same mGPU, the build quality on the ZTE is BY FAR better then that of the Samsung.
Both cost the same, yet after playing around with both of the units, I clearly will say that this company is not YET another "Chinese" knock-off clone company.
YES it is made in CHINA, but yet over 75% of the available electronic devices are produced in CHINA. So what's the difference? Is it the name of the BRAND that you look at first? Or the build quality of the headset?
