I experienced some random lag on the pre-cooked r3 build, and I'm not noticing it on my custom cooked r4. So it must be due to the fact I've removed a lot of the extras; such as live wallpapers, car home, maps, sound recorder, etc..Any speed improvements? I'd assume its just the same as before.
Early reports that deselecting 'WiFi Status Indicator' in R4's kitchen solves the wi-fi disconnecting issue.
Depends on how you describe 'faster' - in the home screen arena using LauncherPro (vs. the same on FroydVillain Hero 2.2) it is marginally quicker but not much in it. When you get to app usage it is much more clear cut. Angry Birds, and my new favourite Fruit Ninja, are both absolute joys to play! On my Hero running 2.2 Angry Birds was glitchy and very laggy, on this device it is amazing and on par with the iPhone experience. Haven't tried many other games but other things like App Installation and the like are all much snappier than on the Hero.
That all said I think the screen justifies the price on its own, especially if you're talking about coming from a Hero.
edit: Oh and live wallpapers run smoothly. Although they 'worked' on FroydVillain the 3d ones mostly didn't launch and the 2d ones were dead laggy.
audio is on the quiet side, but not so when headphones in, i cannot hear it loud
id definatly keep the sgs tbh, ive used my mates and its an awesome phone, which should get even better once 2.2 is released.
the SF on stock orange seems very very laggy compared to it.
R4'd last night, lost 3G internet this morning. Tried deleting and recreating the APN, and I just get "connect failed" when I try re-enabling the data connection. Everything else though is a lot faster, r4 is a definite step up from r3.
No issues for 3g here for me (t-mobile) on R4
