I just came for the Nexus One and absolutely love the Galaxy Nexus. Stock ICS was pretty amazing, but after only having it two days I couldn't resist so I flashed AOKP M5 and Franco Kernel M3. WOW, battery life is amazing and I love all the feat...
I remember when the app was first released it had problems working together with lightflow,and I was wondering if this was still the case?
On my N5 I have no issues with LightFlow and Peek.
No idea why, but I went into recovery and wiped Cache and Dalvik-Cache and it works fine now.
