Just installed the leak on Saturday. Right away seemed much smoother and certainly faster. Wifi did seem to connect faster with fewer drops, but still won't connect if I'm too close to my router (same as HC). All 92 of my Play Store apps automatically restored themselves, which was nice. Is that a new ICS feature or a new Play Store feature? Only asking because I had to manually install everything except my paid apps on my new HTC phone a few months ago.
Having same issues with games as reported, zero response from any ABirds, Stupid Zombies allows targeting but no firing. Zen Pinball HD works like a dream though. Haven't bothered to try Shadowgun or Dead Space.
I noticed Sunday evening that it started stuttering between screens, both on the launcher and the app drawer. 2 shutdown/restarts didn't fix it, so I did a factory reset and it was back to butter smooth. Now, a day later and it's doing it again? WTF? I'm normally not one to complain about a bit of stutter/lag swiping from screen to screen when it's just the way the device is. This seems to me to be degrading quickly from the fresh install. Anyone else experiencing this? Is it possible I have an app that is not playing nice with ICS? Can anyone point me to a blacklist?
I'm considering downgrading, but at the moment it doesn't seem to be 100% reliable.
