i have a samsung q1 running v3 in mimic mode.
no issues.
i want to buy an extended battery for a little more life, but overall, if it is plugged in all the time and only unplug it to move around, it works great.
i got it used on ebay for $300, only a little scratch so i didn't mind. after you put a protective case over it, it looks new again.
touchscreen works fine, you have to use your nail, cause it uses a stylis.
i would recommend it.
