It works on all ROMs. I can confirm that cause I have a chinese MTK6589 phone. However, on my phone, it looks a little streched, and look what happens when I pres the 123 key - the keyboard minimizes for some reason... Im running JB 4.2.2 on a QHD phone (960 x 540 pixels). Any suggestion how to fix this?
