this is not really an issue, but just wondering if anyone else has experienced this. i've noticed that on my ip4 i have to turn the brightness up a lot more to achieve the same amount of brightness as compared to my 2G, even though the max brightness is still brighter on the ip4. but the ip4 seems to trail off/get dimmer a lot faster than the 2G, which seems to dim more evenly, on comparable settings. might be hard to tell from pics tho...
here it is on the minimum setting, both relatively same although tone is different:
on max setting, ip4 is brighter:
turned down by ~1/3, 2G is brighter:
turned down by ~2/3, 2G is brighter, and it's not just cause of the bluish tint:
