Which android miner are people using on their X1's? I just received mine today and wanted to test it. (I wasn't expecting my X1 to come with a screen and even more so a android installed on it.)
CGMINER already appears to be running.
To access it on the LCD itself, open Chrome and browse to
http://127.0.0.1/lcd, log in with user/blackarrow
At this point you should also see what IP address it's allocated itself (otherwise click the settings icon at the bottom of the screen and look at either your wireless settings or your other -> Ethernet settings)
You can then web browse to it from a PC/laptop and add your mining pool details. No need to bugger around in Android trying to start CGMINER.
There are two websites built into it:-
https://ipaddress/ is the white-background one with the meters
http://ipaddress/lcd (or on the unit you can use
http://127.0.0.1/lcd) is the colourful black-background one
Logging in on one machine logs out the other (and the Android browser seems to hate that) hence the recommendation above to use Chrome instead, which at least tells you the account is logged-in elsewhere instead of just hanging. I think it's worth setting up an extra user account on the web interface so the X1 screen can stay logged-in on one while you use the other.
This is my experience so far (X1 arrived yesterday afternoon). All in all it seems like a nice unit. Touch screen is a bit sluggish, but it's a miner not a smartphone. Runs nice and cool and the power supply (despite its incorrectly-spaced CE mark) appears to me fairly well built, with lots of input filtering/protection and insulating sheet between the transistors and case even though they're all insulated-tab devices. No sign of why some of the earlier ones went bang.
SHAME IT'S SEVEN MONTHS LATE!
Still, the sooner those Scrypt miners get taped out and built, the sooner we can get our compensation, eh BA?
