Ok, cool man. I'm happy you have the only stutter free Android phone in existence. Mine is not. This is my 5th Android phone (HTC Hero, Nexus One, Evo 4g, Evo 3d, Gnex). I'm ok with that, because overall this is the best phone in the world. But you don't have to be a douche about it. I've taught photography classes, so I'm pretty sure I know the difference between a crap camera and a good one, and this one is average at best. I've got some great looking shots in bright light, but anything in lower light looks bad. Tons of noise. Lots of motion blur from camera shake - which is just a software flaw because the flash should fire if the exposure calls for a shutter speed below 1/45 or so. I love the instant shutter, but the sensor does not do well at all in low light situations. Because I know photography, I can shoot around these issues, so it's not a deal breaker for me. But HTC, Apple and even Samsung can and have done better.
Go to theverge.com. Request desktop site. Pinch to zoom. If you're not on 4.0.3, enjoy the lag. I can recreate that every time on my phone, and you can go to youtube and see other Nexi doing the same. This was fixed, apparently, in 4.0.3 so I'm hoping things like bookmark scrolling is improved as well.
My widget drawer stutters badly. So either I'm lying or we're just having different experiences. Others on this board have said the same thing. Again, I hope this is fixed in 4.0.3; maybe someone running a ROM can tell us.
Go to your homescreen furthest to the left. Hit the home button. Watch the frame rate drop. This is 100% consistent on my phone and others on this board have reported the same thing. This action is much smoother on my old Evo 3d and my mom's Evo 4g - but the Sense launcher has always been smooth.
Again, I am an diehard Apple hater and Android lover, but to pretend like Android is perfect and doesn't have some work to do in the smoothness department is not reality. Sure it's the best OS by FAR, but is it perfect? No. Luckily Google is working on it and 4.0.3 is supposed to be a big improvement.
