On-device buttons, optical zoom, native H.264 hardware.
Garbage; do not buy this overpriced toy. It's only "good" because it comes with a stand, but newer webcams are coming out with the threading for mounting to a simple $20 stand.
A very inexpensive yet capable phone.
At a glance, it seems okay. Android and every app I've seen have many UI flaws, but that's not the X20's fault.
After a week of use, I have to say this is a fantastic phone. It's the perfect beginner's smartphone and there's nothing I've done that's been limited in any way whatsoever by its specifications. I have not run out of storage or memory.. not even close. Do note that I haven't played any games, and I probably never will.
I am really ticked that it doesn't have OTG support, so I can't use the microSD for anything but charging. Powering off, pulling my charging dongle out, removing the half-case, removing the battery cover, removing the battery and moving the CD card back and forth is an awful, awful, way for me to edit files.
The minimum volume is way too loud.
The bottom microUSB port works for a USB key.
A waterproof camera with an optical zoom.

I had a brick-like red cell phone with a slide-out long keyboard.
