Do any of the current kernals reduce/eliminate the wake lag? - Samsung Epic 4G Touch

Anyone know if the slow to wake problems have been eliminated on any current kernal/rom? I took my sd card out which helped a little but its still pretty bad.

What exactly is the wake lag? Are you talking a out the two seconds after pressing the power button?

I think that's what he's referring to.
Sent from the future.

That is due to the SD card check that the phone performs apparently. It's just the way samsung's phone works. Try removing the card and see if there's a difference.
And no, there is no fix for it ATM.

yeah i have the same issue, taking my sd card out made it speed up a little bit. it seems to be slower sometimes and faster others. Perhaps it's part of the cpu throttling for sleep mode? What ROM are you using? I know Calkulin's has battery saver script that throttles the cpu down pretty far for sleep mode.

Put your sd card back and flash Blazer. No lag!

[Q] Wake lag?

Is anyone else experiencing a 1-2 a second a wake lag? I have tried using a low res wallpaper, but that doesn't seem to help. Any suggestions are much appreciated. Thank you in advance

No wake lag here. Did you try a reboot?

Could be an app. Apps have the another to do whatever they please when the screen turns on. Good app developers don't cause issues so don't go crazy deleting all apps. Just keep that in mind.

It happens only when I try to unlock after a bit of sleeping. Happened on stock and EB. It Isn't that big of a deal, it's just a bit annoying.. haha
It has happened to me a few times. It would not come on. I had to hit button on side 3-4 times before it did. Just random times it has done it though. I'm not sweating it.

I have the same issue, can't figure it out. That hesitation is very annoying.
None whatsoever here with a high res live wallpaper. Stock. Already over 100 apps installed. Lots of widgets.
Set CPU or anything like?
I'm on the sgs4g... There I'd a thread over there about slow wake also..

Had a noticeable lag after wake. Ran the dsexton tweak and this http://forum.xda-developers.com/showthread.php?p=18739721.
Phone is wayyyy more responsive all around. Especially after wake. Don't notice any lag.

I experienced the lag when I inserted a micro sd into the phone. the card was an 8gb class 6. Once it was removed, the wake up lag disappeared strangely.

Same setup on EB 1.0 with no lag
MERCaBeast w/ Eagle and a dose of Adrenaline Charger

This doesn't make sense but...

For some reason when my battery gets real low, like below 5%, my phone starts to roam and I have no data.
If I reboot my phone it comes back.
I'm on CodeName Alpha 2 and EL29 modem.
Is this just a bug or something else?

Check your power saving settings. It might shut off your internet connection at 5%

ICS Problems

This has been pretty much been the most frustrating update process of my 4 Android devices that I have owned.
Hoping some of the sharp people here can help me out.
Buttons Not Working - About every third or fourth time I wake my phone my physical buttons do not work. I have to put the phone to sleep and re-wake (sometimes multiple times) to get my phone's buttons to work.
Excessive Battery Drain - Yikes!!! I have uninstalled all my apps, and it is still occurring. Any other ideas to figure out what might be causing this?
Constant 3G data movement - When wi-fi is off, my phone is constantly pushing 3g data up and down....non-stop!
Excessive Phone Heat - My phone is running like a furnace.
Now, I think the last three are probably connected in some way.

That is not ICS you have something running in the background. That would cause all of that. Get a battery monitor app and see what is running

I am glad I am not the only ones with these problems.
It has to be a ICS function that is causing the excessive battery drain.
I currently have no non stock apps installed.
I have noticed that the battery ran from 100% to 25% but battery drain had no slowed considerably....maybe faulty logic in how they are calculating percentages?
The one I would really like to solve is the buttons not working, as there will be lots of battery related threads as more and more people upgrade.

The malfunctioning buttons have been happening to some of us on every ROM, whether it's Gingerbread or ICS. It happens to mine on stock GB or stock I'VE.
Just so you know, you can tap the volume Roche to wake up the buttons. You don't have to cycle the screen. Tap the volume button, wait second or so and you will see the capacitive buttons blink once... That means they've reset. Sometimes you have to do it twice.

Same issue here with the retarded battery life, stock rooted FF18. It's pathetic. Constant battery drain while "sleeping", with wifi on or off. Guess i'll have to try a different ROM.

Actually rule a ton of people are reporting these exact same issues in the sprint community running factory ics update. So these issues are pretty common. I am also experiencing quite a few myself.

I tried this yesterday when I was getting terrible battery life. I went from fully charged to dead in 3 hours flat.
I ended up doing a factory reset with sfhub's one-click and am slowly testing and restoring apps to see what's acting as a vampire.

You should try it again if it didn't work!
Not everyone's issue is going to be caused by the same thing. What may work for you may not always work for everyone else. It may be an app or ICS in general causing the issue.

Things i hate about the recent ics update

Los problems i never had before
Bad battery life
No mass storage usb mode
The worst is... It makes sound when you power it off now. Who was the genius that thought that one up? Like on the middle of a movie theater or in a meeting.
This is driving me to root my phone. Gj Samsung.

1. Let the kernel sit sometimes it takes a while to set in. If not try a factory reset. Resets are usually needed after an Android update to function properly. My batt did drop a lil than on GB but not too bad.
2. I believe sfhub has a tweak to enable USB storage back if you need it that bad.
3. When in the movie theater or a meeting a phone should be on vibrate from the start. All it takes is a drop down of the notification bar and voila vibrate or silent without powering down. But if you chose to power off the sound it makes would be silenced.
None of your issues sound as bad as what many others are experiencing..

Alternative theory for delayed screen wake

I noticed that I barely have any screen wake lag, but when my sd card is in the phone, I have noticeable screen wake lag. Every time I take my sd card out to test my theory, the lag is gone.
Can anyone else reproduce this?

I had a sd card that was going bad that play3d havoc with my first note 1. So bad I took it back and had 5he phone replaced. Only to have it happen again with the replacement. Pulledncard and replaced and never had a problem again.

well my card isn't causing any problems.. it works fine and i can access everything on it fine.. i just notice the screen lag when its in and not when its out.. simple as that.
Yeah was able to th a t with mine too. Not saying it is your issue it just happened to be mine and related it you as something you might try as pulling your card out fixes your problem.
Is it always present with the card in?
