I’ve tried using some of the gameloft titles on my samsung vibrant such as Nova, Hero of Sparta, and the gangstar game. They seemed to work at first but a few minutes in my phone started freaking out, the game would stop, my phone would go black and the only aspect of my phone that responded were the softkeys but they would do nothing beyond lighting up. I had to remove the battery to restart my phone and even on multiple restarts my phone would load really slow and then go black again. I found that I had a race against time to go into the application menu and uninstall the games before the phone would go black and lock up. After numerous tries I finally got all of the games uninstalled from my phone and after a final restart the phone started to act normally again. I contacted gameloft with the issues I was having, they sent me two links to download updated versions of the hero of sparta and gangstar game that they claimed shouldn’t cause problems. I redownloaded those specific titles, installed and, like before, they seemed to be working fine at first but they still eventually caused my phone to brick on me forcing me to, once again, have to quickly uninstall them as my phone was loading its usual software from a hard restart. My hope is that gameloft will work harder to fix the problems and maybe when my vibrant finally gets the 2.2 OS update it will be better suited to run these more high-end games.
