eh? right after i installed cm9 for the first time, i already had graphical glitches which made it impossible to read any text on my screen (it made all the letters dissapear, after a while they came back), while i hadnt installed anything yet. Doesnt seem stable to me
I find if you install CM9, then set the phone up, i.e all the settings you want. Then flash the Gapps, the phone works pretty well. And also I used Pimp My Rom to use the RAM compression option, let me save things like Facebook, and games, in RAM without slowing the phone down!
