Sloppy Animations still persist in iOS 4.2

Trat said:
But the problem here isn't 'education': I know exactly what you might be seeing. I also informed you that I have experienced stuttering when I was on my 3G using a 3.x beta; there was one build that really messed up the camera / photo's app i.e. started a memory leak.

I'm just saying that I don't experience anything like from your description: my device transitions between apps as smooth as always, after following your guide.

If you want to do a video be my guest. But I doubt you will show me anything that I haven't materialized already from your earlier statements.

I also want to stress that this is not a matter of not wanting to admit that there might (not) be a problem. I found that assumption mind boggling.

You obviously don't know what I'm seeing. So therefore I have to educate you further.

If you have an iPhone 4 and you're running 4.1, you have the problem.

Just because you don't notice the problem, you can't say it doesn't exist on your device. Same hardware, same software. It's a software issue as it wasn't in 4.0.2. I've restored my iPhone plenty of times to rule out some sort of bad install. Also, I've installed 4.1 from 2 different computers too (so that rules out my computer). I've also installed it using iTunes 9 and 10 to rule out an iTunes bug.

Trust me, it's there. I'll make a video and you'll say "Yeah, mine does that. I didn't think that was the issue"

Good day.

I don't have the issues you are describing. According to your theory, I have a different iPhone with a different 4.1 build. According to mine, the symptoms you're describing must be due to something else than a broken camera.app.

Who's in need of education here? Post a follow up if you want; I'll we checking back on this topic tomorrow and see how your video turned out.

In the meantime, I will be using my special iPhone and will be making photos and switch back and fort between the camera.app and other apps without any hiccups and without fooling myself with saloon developer / bug hunting dissonance.

Until tomorrow!

Well aren't you special.

How about this for you:

I have NO 3rd party apps installed
Push is off
Restored as new
HDR off (doesn't make a difference when it's on)

As far as I can see, my iPhone is as vanilla as it can be. I'm certain you have more stuff than me.

Also, I never said that you have a special iPhone. I said that your iPhone is the same as mine. Same hardware and same software.

Let me know what settings you're using because maybe there's a special combination of settings that make 4.1 run like 4.0.2 used to.

When I ran that app before 4.1, I noticed almost NO CPU activity wheny iPhone was idle. Now, there are significant spikes in activity that may be causing some of the animations to jerk.

Also, opening camera definitely affects performance. Try the steps that I noted a few posts up. I can reproduce it every time on both iPhone 4s that are in my household.

I was able to reproduce the problems in the Photo and Camera apps, but just there.

Everything else open and closes normally, and I don't feel any slowdown.

I also discovered that if I stop using the phone for a couple of minutes, the problems of the animation when opening the Photo and Camera apps is gone.

So yeah, there might be a bug with these apps, but the extent of how much it affects the user might depend in other factors.

It doesn't affect me other than it's just bad to watch when everything else is smooth as can be. It kind of jumps out from the rest because of it.

You say it goes away after a few minutes? Interesting, I haven't tried that.

Thank you for reproducing the bug for me. It's really there and I'm not crazy.

Edit: I just tried leaving my iPhone alone for 15 minutes after reproducing the bug and waited for about 15 minutes. When I opened photos again, it still skipped.

How long should I wait for?
 
PLEASE make a video to show the issue on 4.1, i need to see this as everyone has their own opinions ...
 
FWIW - this 'problem' does not seem to exist in iOS 4.2 beta 2 though to be honest, I could never reproduce it on 4.1 either.

Why would it? The HDR features would surely be part of camera apps, not Springboard.

Memory leak? Runaway process consuming CPU cycles? Apple obviously didn't change the animation. There's something else going on in the background that's eating up some of the processing power of the iPhone so that simple animations are stuttering.

There's tons of reasons why a new feature (untested outside of Apple even) would cause problems. You don't know if HDR is strictly a camera feature or if it has some sort of background daemon for it. We know that both photos and camera are affected so perhaps HDR spans into photos app as well.

When the 4.1 jailbreak comes out, I'll be testing it and finding out what process is chewing up the CPU and I'm going to kill it.
 
Oddly enough, today I noticed my iPhone 4 stutter when respringing, but it was after pressing the home button while playing FIFA 11.

The respring animation was a little slower and a bit more juddery than normal. And it does it every single time while playing the FIFA 11 app.

I've opened my Camera app and Photos app and used them both before pressing the home button, and can't replicate any slower respring animations there.

Odd.

I'm not talking about the respring (I'm assuming that you mean returning to the homescreen).

I'm talking about launching apps. After opening and closing Camera and Photos, I start getting a slight pause when opening some apps (mostly Photos, but it also happens with Voice Memos and Camera.)
 
wow so i was at the apple store and all their iphones had ios 4.1 and it SUCKS compared to my 4.0.2, hate to think i HAVE to upgrade to 4.1 so i can use my phone and unlock it for t-mobile. ugh.

Is this a serious post?

Yes why wouldn't it be? I just don't like how I will have to update to 4.1 so I can unlock my iPhone 4. Ios4.1 seems very glitchy at the apple store

Just checking.

Anyway, I was at Best Buy today and I tried out their iPod touch 4th gen and it also suffers from the laggy animations. It has 4.1 obviously.

Is the 3GS affected by this?

Probably because the 4.1 Jailbreak is believed not to allow network unlocking at all under 4.1. :confused:

Are you serious?

BTW, OP, my 4.1 iPhone (have had a 4.0.2 as well) does not lag like you've described. Clearly, not everyone is experiencing the same things. You want lag though? Try a stock Samsung Galaxy S, any version except the Epic 4G. :p

It doesn't lag in a traditional sense. The animation just skips when opening certain applications after certain conditions.

Every iPhone 4 running 4.1 does it. You just may not be noticing it.

Try this one.

First quit all your apps from the Multitasking bar so to be sure that we're running the same way.

1. Open Safari
2. Load a web page (I do Apple.com)
3. Press the button on the bottom right (the new tab button)
4. You'll see a your webpage with an (x) in the corner
5. Do not touch anything and press the home button.
6. Open Safari again (the animation should be smooth as butter so far)
7. Turn the iPhone to landscape mode and wait for Safari to turn sidways
8. With your iPhone still sideways, press the home button.
9. Now turn your iPhone back to normal and tap Safari again.
10. This time the animation is just the last half of the normal animation. Safari just pops into place with a short zoom.

Normally, you'll have the homescreen icons flying off the screen at the same time the window smoothly zooms toward you.

If you did my steps correctly, you should see that Safari does a short version of the normal animation and that the first half of the animation (flying icons) is skipped altogether.

I know that you're not likely going to do all of that stuff on a daily basis, it's just an experiment that works for me every single time to produce the bad animation.

You may also notice photos or camera doing this after using the camera.

So please follow my instructions EXACTLY and then tell me what it looks like.
 
Here's what the correct animation looks like:
http://www.youtube.com/watch?v=CyHmDS7kyQE

Here's what the wrong animation looks like (the stutter). This is what I'm talking about when I say the iPhone animation is stuttering.
http://www.youtube.com/watch?v=yFlAosKb4Zo

If you can't tell what's different about these 2 videos then you probably think your iPhone is "just fine" or "no different than before"

Those who CAN tell the difference know exactly what I'm talking about and they too see the difference on their iPhone.

To watch the powerful iPhone 4 stutter like this is unacceptable. Especially this early on in the release.

Please watch the 2 videos and tell me what you think.

Watch this video too at exactly 3:02 when he launches camera. It does the same exact stutter that some of you are saying doesn't exist. It just snaps open with almost no springboard animation. You basically only get the last few frames of it.

Watch this guy open his camera app at exactly 5:25:
http://www.youtube.com/watch?v=YOSzfs9Fmic&feature=related Same thing. Why does it pause like that? It completely skips the entire first part of the animation!
 
I followed both of your guides - there's no slowdown for me.

Your sample is way too small to make the statement that every phone has the problem.
