Not a good analogy - how often do you have to deal with the gas door on your car... maybe once every week or two? Now, how often do you turn your phone on every day? I think maybe you'd have more of a problem with your "shiny new car" if every time you went to open the door to get in, nothing happened when you pulled on the handle... but then it opened two seconds later? How about turning the key in the ignition and the car didn't start? Some of the people here would then be turning the key again just as the car started (ever hear that spine cringing sound?).

My delay is just as bad as the OP's video, if not worse. I just did some things to see what would happen:

With Widget Locker enabled:

- turn on phone, experience delay

- turn on phone, do NOT unlock lock screen, turn off phone w/ power button, immediately turn it back on - virtually no delay. (consistently repeatable).

-turn on phone, unlock screen, turn off phone w/ power button, immediately turn the phone back on - experience delay. (variable in how often I can repeat this).

With standard lock screen:

Experience delays regardless. If I turn the phone off and on, off and on, sometimes the delay is less if I turn it back on RIGHT after the screen fades to complete black. Other times, it doesn't matter how fast I turn it back on.

Incidentally, since other people are testing out the media scanning and how this problem is related to the SD card, if any of you have Fast Burst Camera installed, if you press menu, gallery, the media scanner goes nuts.
[Samsung Epic 4G Touch] GooseChaser:
great find gentlemen! Same wake time as the OP, I even timed it with his video to make sure. Using 32gb Class 2 Sandisk card. With card OUT the phone wakes instantly.

Not a deal breaker, but I have learned to adapt to the delay.

I realize you may not have a sense of urgency in your life, but some people in their professional lives need their phone to turn on NOW, not in 2 seconds.

As to the topic at hand, I have this same delay and it drives me nuts.

Does anyone else have a similar 2 second delay when trying to get the screen to come on to end a call?

Tried reporting this all through Samsung chat support just for kicks. Of course I was connected to an obviously limited English speaker named "Suzanne" and nothing was resolved and she claimed there hadn't been any other reports of it. I suppose I should call and report it, but I'd expect the same result. :/
[Samsung Epic 4G Touch] coiledwire:
Just some observations:

32gb class10 = unlock delay

16gb class6 = unlock delay

8gb class2 = unlock delay

No SD card = no delay

Another person earlier in this tread suggested this SD card dependence, and I tend to agree. The phone does seems to some scanning of the SD when unlocking, quite possibly searching for media or file changes. Since the SD can be swithced and/or removed without turning the phone off, I wonder if this is some sort of a "safe" scan during the unlock. At any rate, it appears to be something that can be addressed with a maintenance update.

[Samsung Epic 4G Touch] tool2269:
I agree with this, but i'm not sure why there is no delay when the phone is plugged into the charger, not matter what card is inserted.
[Samsung Epic 4G Touch] coiledwire:
Very true. Good point.

[Samsung Epic 4G Touch] frifox:
after getting used to pushing the power button and sliding to unlock in one action for years this 2 sec delay is driving some of us nuts. now we have to press power button, wait, and only then swipe. when i first got the phone i was swiping like 3 times before it actually was unlocking but now i'm getting used to waiting before swiping the lockscreen so its all good now :D
[Samsung Epic 4G Touch] alnova1:
Ok...so how does this 2 second delay affect you in your professional life? I use mine everyday for my work and depend on it and it hasn't affected me...please explain.
[Samsung Epic 4G Touch] wase4711:
so, 2 second delay causes you stress in your "professional" life?

Unless you are a brain surgeon, doing microsurgery on an infant, it boggles my mind to think that a 2 second delay is an "issue" to anyone...

[Samsung Epic 4G Touch] manekineko:
Phone probably isn't going fully to sleep or powering off the SD card slot on the charger.
[Samsung Epic 4G Touch] :
Here's my take on the delay. Is it a deal breaker? No. Can I get used to it? Yes. If I had a choice to have a quick wake and have the cpu go into deep sleep (not affecting battery life) I would definitely like to know a way. In that way, the way people perceive this delay can be viewed as a preference. If someone says, "I'd prefer to have no delay" then just because you don't care about the delay doesn't mean we should just say things to shut down further conversation about it.

I'd like to think of XDA (among other things) a think tank of modding our phones. Discussions like this promote that way. I can see if everyone just wanted to complain about it and not help find a solution that it can be irritatingly repetitive, however, trying to stop members from exploring ways to achieve what they want seems a little backwards in my opinion. Don't want to start anything, just stating my opinion.

FYI- I logged my CPU frequency with CPU spy as it was plugged into the charger and it does seem that the CPU does not go into deep sleep. It will stay at 200 mhz (for me) with the screen off.
[Samsung Epic 4G Touch] moeinyoho:
the wake up lag is a b**** lol
[Samsung Epic 4G Touch] dallastx:
I have a 32 gig Class 10 card and have 2-3 sec delay.....Seems normal to me. Because if you turn the phone on right when it goes off it will instantly come back on. If you let it sit for about 10 sec, than it goes to sleep an wake has a delay. Software issue couldn't be a hardware issue. Samsung knew the phone wake process before they shipped them to sprint. I see it has a convenience issue, turned into a bug and the first and "only" update will fix this lol
[Samsung Epic 4G Touch] qbking77:
I have a 16gb sd card... had screen wake lock lag.... Took sd card out, same problem.
[Samsung Epic 4G Touch] snakedoc34:
Just wanted to add that I had the 2 second lag like everyone else is reporting... didn't bother me at all though... I had an 8gb class 4 microsd but when I upgraded to an amazon essentials 16gb class 10 card, the lag went away... the phone wakes up instantly... My phone is unrooted, straight stock.
[Samsung Epic 4G Touch] sling:
ha I haven't used card for well over week due to lag then come across your post.

My 16GB Transcend class 6 gave me 2-3 second lag so I dumped card use all together until today.

I let device go into sleep installed same card turned on device and Media Read took place card synced.

NO MORE WAKE UP LAG!!!!!!!!!!!!!!!!!!!!!!!!

Device wakes up fast zero zero delay amazing.

---------- Post added at 09:57 AM ---------- Previous post was at 09:35 AM ----------

Adding to post above.

Im thinking issue is due to device OS not fully synced with hardware.

I Installed card when first getting device noticing media card read sync displayed on tool bar twice.

When first power on with card in stalled this time it only synced once so issue is definitely OS related no doubt.

I wont be doing full power off , Battery pull or taking card out anytime soon that's f,sure.

---------- Post added at 10:14 AM ---------- Previous post was at 09:57 AM ----------

The true test for me all is well.

Took some pictures they went to SD card then I set one as lock screen wallpaper.

No wake up lag taking place :)

/thread necro

I just noticed this happening for me. Strangely the first two weeks of having the device I didn't have any issues with the phone waking immediately, but now I'm having the 2-3 second delay even without an SD card in the phone.

I've gone so far as to reload a stock vanilla image, and it's still behaving the same way.

While not a dealbreaker device-wise for me, it's an annoyance to suddenly happen. I first thought that it might have been a ROM that I was using, but considering it's happening with an OEM build without any apps installed or Google accounts added, it seems strange to say the least.

Has anyone had any success if getting rid of the lag once they noticed it?
[Samsung Epic 4G Touch] luckychef28:
Maybe a solution

I have been experiencing the same issue, and it drives me nuts. It's definitely SD related. I'm using a SanDisk 32 class 2. I read a few post about using SD booster set at 2048, which seemed like a good idea, but it didn't work for me. But when I set it to 1024, applied, and rebooted the lag was gone. 2.5 sec to .5 sec. Worth giving it a try.
[Samsung Epic 4G Touch] xluryan:
Dude, unsubscribe from this thread and stop posting in here. You have nothing at all to add to this thread. If you don't care about the 2 second delay, good for you. I'm a computer programmer, not a brain surgeon, and not someone who's going to be affected by a 2 second delay. But it's mildly annoying, and if there's a fix then I want it.

I don't give two ****s about what you think of me being annoyed by a 2 second delay, and neither does anyone else, so just stop trying to make fun of people in this thread and piss off.

Maybe "issue" is the wrong word to use. This definitely isn't an issue for any of use using the phone, but it's just very mildly annoying. Would you rather have an insignificant rust spot on your car, or none at all? You'd be disobeying logic to pick the rust spot.

Unless of course the rust spot looked like Abraham Lincoln or something else equally as cool ;)
[Samsung Epic 4G Touch] DutchDogg54:
I hate bearing bad news...but this didn't work for me. I tried 1024, 2048, 3072 & 4096. I was

hoping this would work :confused:

PS - I also tried the window animations setting: nope; also tried the screen timeout setting adjustment: nope
[Samsung Epic 4G Touch] xluryan:
I think the reason it doesn't happen when it's plugged in is because the phone isn't actually asleep. I would bet there is some code to check the SD card when waking up, but not necessarily when turning the screen on.

Since the phone is already awake when you turn the screen on and it's plugged in, you get no SD card scan, and therefore no delay.
[Samsung Epic 4G Touch] naerok:
get the autostarts app (https://market.android.com/details?id=com.elsdoerfer.android.autostarts) and disable the processes like system update that get triggered on screen on/off. after disable the screen on/off processes, my phone screen wakeup delay is almost none
[Samsung Epic 4G Touch] CrozB:
Just tried this app disabling the apps in the screen on section and it does help. It is not 100% as fast a no SD Card in the phone, but really close. And close enough to eliminate that doubt "did I actually press the power button".

Thanks

Is this a dead issue that people just continue to suffer from. Cause its really annoying, maybe

[Samsung Epic 4G Touch] zaneyard:
Anyone who is still having this problem try blazer rom.

"SD Card Read Ahead Tweak"

I think that might be something that could fix it?

Right now I'm running Calkulin's E4GT v2.0.1a and I have a significant delay with my sd card in, no delay with it out.

Might image and flash blazer to see if this fixes the problem.
[Samsung Epic 4G Touch] Isriam:
Any more updates on this? I have it with Calkulins EL13 rom. Annoying me. I've tried all the solutions here and it seems faster with the sd card out, but not instant like past android devices i've owned.
[Samsung Epic 4G Touch] asbjörn:
I've had it no matter the rom or kernel. Maybe it is due to sd card...? Either way, nothing so far has been done about it.
[Samsung Epic 4G Touch] Isriam:
So it doesn't lag on AC power, and I found out today that it doesn't lag until the battery drops below about 95%. I think it is some power saving feature or something.
[Samsung Epic 4G Touch] MrDowntown12:

[Samsung Epic 4G Touch] SimboXXX:
I have this wake-lag problem on international i9100 version. I found this thread because the thread in the i9100 forum has found no solution.

I have tried different roms and kernels (currently on 2.3.6). Have tried setting the min cpu speed to 500 & 800. Tried all the settings changes mentioned in this thread. Tried siyahKernel with widgetlocker etc.

Nothing works.

Taking the sd out makes a little difference.

Sure, 2-3 secs is not a lot of time, but when you are waking up your phone 100s of times a day it gets pretty irritating.

Hoping ICS will fix this.
[Samsung Epic 4G Touch] Isriam:
I can confirm that softlocker free will fix this issue. It's not the fix i want though.
[Samsung Epic 4G Touch] AndroiDemon:
Same problem here!!

Epic Touch 4G

32 GB Sandisk

EXACT same lag as video.

I tried autostarts, SD booster, SD Speed increase, NOTHING worked. Took the SD card out, no wake lock lag at all.

Can someone PLEASE find a tweak/app/work-around/something for this absurd annoyance???
[Samsung Epic 4G Touch] Iandv:
what I did

This is how I fixed the lag. I dont know if it will work for anyone else. I turned off the phone, took the sd card out, turned it back on and wait until everything loads. Then I put the sd card back in there and voala no more wake lags and I still can use my sd card. The only time the wake lags come back is when I reboot the phone without doing this process all over again.
[Samsung Epic 4G Touch] SimboXXX:
I don't understand exactly - how can you put the sd in without pulling out the battery? I'm obviously misunderstanding.

ok, I guess on the Epic the card is hot-swappable. I got the i9100 :/
[Samsung Epic 4G Touch] p2w:
Its not about SD-card but deepsleep.

I tested weather or not this delay/lag is because of SD card inside my S2. I took off the card but it didn't help a bit. It's pretty obvious because there is no wake-up delay when my phone is recharging or connected to my computer. I have heard that there is a powersaving feature called deeplseep in the new ICS version, so the problem must be deep sleep related. Does anybody know a way to make the deepsleep not so deep, so that it wouln't take 2-3 secs to turn on the screen. 0,5 to 1,5 sec delay wouldn't bother so much but 2-3 secs is too long time when you are turning your device on hundreds of times a day. A custom ROM that would address this problem would be handy as well. Anybody know one?
[Samsung Epic 4G Touch] tdunham:
This is a super old thread dude. You may be better off to start a new one. But not to spam the thread :), I use Calks ICS 1.5, tweaked and pretty fast, but everyone will tell you that the one they are running is the best! LOL

[Samsung Epic 4G Touch] cruiserandmax:
I have noticed that without an SD card installed this wakeup lag is completely gone!! Though operating without an added SD card is kind of defeating it does make the phone consistently wake-up from sleep in a split second.
[Samsung Epic 4G Touch] ora282:
Mine seems to be related to the screen mode in display settings. Movie mode has the fastest wake and dynamic has the slowest. I believe this is because the phone has to adjust the saturation of the wallpaper before the phone wakes.
[Samsung Epic 4G Touch] jedics:
slow wake

When I fist got the S2 with a stock rom it didnt wake this slow, even after first putting slimrom on it I dont think it was this slow but now its really noticeable. It has to be faster than this.

[Galaxy S II Q&A, Help & Troubleshooting] StevenBX:
I'm a new Galaxy S II (and new Android) user, and am a bit disappointed in the battery life of my new phone. It was running down extremely quickly yesterday, only lasting about 12 hours with relatively normal use (sending half a dozen texts, downloading 2 apps, checking Facebook and Twitter once an hour or so for a couple of minutes throughout the day). I allowed the phone to discharge completely and charged it fully last night, but this morning nothing seems to have improved. I burned up 10% of the battery in half an hour sending 2 texts, checking my emails, Facebook and Twitter and downloading and trying out a couple of apps.

I'm anxious to know if there's a bit of a burn-in time with the battery on this thing - does it get better after a few charges? I see a lot of people saying they can have the phone on for a few days in some cases, but that's definitely not my experience thus far.

I've installed JuiceDefender (balanced profile), AutoKiller Memory and Advanced Task Killer to try to sort things out but none of them seem to having too much effect and to be quite honest I'd rather not have to compromise my experience by running a number of apps like this to try to extend my battery life at all (nor do I want to have to turn the brightness right down to an unusable level, or set black wallpapers for example).

Does anyone have any real advice on this? I'm starting to think that switching ROMs might be worthwhile? I see that the leaked 2.3.4 ROM seems to have better battery life - is this correct? I'm a bit reluctant to switch to any other unofficial ROMs as there are so many I wouldn't know where to start. It seems they all make a lot of changes but I'd want to keep as close to the stock feel as possible, just with better battery life.
[Galaxy S II Q&A, Help & Troubleshooting] poch_1421:
no one uses stock roms/kernels nowadays. u should flash a custom rom or kernel since they provided optimizations to batt life.
[Galaxy S II Q&A, Help & Troubleshooting] angelomaldito:
It is argued that task killers and memory killers will only make the problem worse. Juice Defender might be useful if you are using it for scheduling sync and turning WI-FI off when the screen is off, but this feature is only present in the Ultimate edition and you can turn off sync and WI-FI manually if you want. Also beware of rogue apps which are syncing all the time. It is normally the main reason of poor battery life.

Other reason, is that whereas powerful tech specs for phones were rapidly developed, battery technology didn't followed the pace. Our simply batteries cannot cope with our beasts.

Also, there is a thing that it's called "new phone battery blues" which is described as poor battery life due to excessive use of a new powerful toy. After you use your phone normally, for the purposes that normally people use a phone, your battery life will became better.

That said, personally I have a spare battery and a spare charger, and when the battery being used is low, I replace it with the charged one. Sometimes it is necessary, sometimes not.
[Galaxy S II Q&A, Help & Troubleshooting] StevenBX:
They also have a tendency to look very tacky I think though. I think Samsung's skin and widgets are pretty nice and don't care too much for the mods I see in the screens of most ROMs. I'm really looking for something very similar to stock, except with better battery life if there are any suggestions? That's why I was thinking of just jumping to the leaked 2.3.4 if it had any noticeable impact on battery life...
[Galaxy S II Q&A, Help & Troubleshooting] veyka:
Try using better battery stats, link in my sig, to see if you have any wakelocks, the thread has a good howto on using it.

The biggest thing that uses the battery on this phone is the screen, you will get between 4 and 6 hours of screen on time depending on usage and screen brightness.

[Galaxy S II Q&A, Help & Troubleshooting] nofam:
Fair point - not all of the roms are everyone's cup of tea. My advice, as a starting point is to flash the stock XXKH3 variant for your area, and then flash a custom kernel, such as Ninphetamine's or Hardcore's Speedmod. This will greatly help with battery life, and also give you the ability (via root access) to use Titanium Backup to freeze apps and services you're not using, which is often the major cause of battery drain through 'wakelocks'; apps that prevent your phone from entering Deep Sleep, or continuously wake it up.
