Hola!
So I really really REALLY like SGS2 and would love to get one. But before I do, one question...
I like to keep my phone plugged in and turned on while I'm at work or at home at the computer. But having done some reading, I see that SGS2 is susceptible to the screen burn in issue. Is that true? Should I not get it in that case?
As I said, I REALLY like the phone, but if I need to change my usage habits just to avoid a known issue, I'd rather look for an alternative.

It's got a SAMOLED screen. Google's your friend...

^^ Ditto!
OP - SGS2 is NOT for you. Further if you like to keep a phone plugged into computer at all times, I suggest the much cheaper MagicJack.
yes, I'm aware of what type of screen it has, thank you. That's the reason I asked about the issue.
I've never had a phone with an amoled screen, so I can only go off of others' experience.
What I'm wondering about is if there are any solutions that would go along with my usage habits. I don't remember what phone I was reading about (Nexus One?), but it had a feature where it would display a moving clock screensaver when docked in. Something along those lines when plugged into USB? Or maybe there are some new technology improvements in SGS2 that I don't know about?

If you're going to leave the screen on for a long time every day on the same screen, there will be a burn in. But I imagine with normal use (even for extended periods of time, but the screen changes screens often) there shouldn't be any problems.
So I'd probably skip on this phone if you leave the phone on for 8 hours on the same screen. Maybe the HTC Sensation? Also a VERY good phone, just not as good as the SGS2 ^^

Yeah, my main concern is when I'm at work, since I'm at my desk most of the time there. I'll probably have to settle on the Sensation after all. As you said, it's really nice, but not quite as good as SGS2. Such a shame >_<
Thanks for the suggestion!
Why do you keep the screen on all day?

I text a lot and get a bunch of emails usually. It really annoys me to have to turn on/unlock the phone every time I get a notification. It's nice to see it a glance when it's on the desk in front of you.

text app like handcent allows your screen to turn on when you receive a message with a popup message, you can read it immediately and reply instantly without pressing any extra button.

Yeah, I actually use it. But I don't always read the texts right away while working. And if the phone is unplugged, it will go back to sleep after a popup shows up.
It's just a personal preference =)
Its funny how lazy people have gotten.
I had original sgs2 for about a year and left it on bright screens with random things on with no burn in issues.
Had sgs2 for a month and have left it on overnight while on lockscreen(bright orange) and others and have no burn in issues.
I haven't personally seen any claims of burn on these forums or sgs forums. Just mostly people asking about it.

Ha, have to admit, I'm pretty lazy
But that's interesting that there's been no reports of it happening... Hmm wonder if I should just say F it and go for it. But then again, I guess you'd have to be consistent about leaving your screen on for long periods of time. I doubt it would burn in if you leave it on for a night or two.
Why don't you go search some of the SGS and variant threads as well as the Nexus S. They use the same screen technology and have been out a lot longer. If they aren't experiencing issues you probably won't either.

I did search before creating the thread. I saw some people reporting burn ins on other phones, but wasn't sure if anything has been improved lately technology-wise that could prevent the issue. I guess not...
I do realize though that it's quite early to see such reports on SGS2.

yes you can and will burn in your AMOLED screen if left on all the time.
my nexus one actually has in the instruction manual to not use the phone for more than 30 minutes of screen on time. that's actually written in the OFFICIAL manual. perhaps later generations of amoled from samsung got better, but burn in still will happen.
note: i use my nexus one with screen on for 3 hours at a time, but i just dont leave a static image in one spot. i'm constantly web browsing etc so no real issue of major burn in. however my status bar did get burnt into the screen after the first month of owning the nexus one. not bad, but present.

there are PLENTY of threads right here at XDA complaining about burn in on samsung amoled and super amoled screens. start in the nexus one forum, then search the galaxy s forum.
Has there been any resolution to the 1 - 2 second wake up lag yet? I've seen several "fixes" like reducing the resolution of the lock screen wallpaper etc but none of these work for me. I've experienced the lag on KE7 stock ROM, Cognition ROM, Villain ROM and now on Lite'ning ROM.
Not sure if I agree that it's being caused by the CPU clocking down when the phone is asleep either. When I use SetCPU to set the minimum clock speed to 1.2Ghz the wake up lag is still there.
Also the lag does not occur when the phone is plugged in and SetCPU is telling me that the phone still clocks down to 200Mhz when asleep and plugged in.
Someone must have some idea what is causing this #$%$## lag.
I use Softlocker Free for this.. Works perfect for me, a bit reduced battery life but not enough to stop me from using it..
Thanks for the reply. I tried Softlocker a while back and found the battery drain pretty heavy. Might give it another go. I was thinking there must be a permanent fix for this lag problem though. Hopefully it's just a matter of someone finding it.
I also noticed the lag on my old i9000 as soon as I updated to GB so know this is across the different samsung models on GB in addition to SGS2. I really do think its the clock going down despite your setcpu settings. Use cpuspy free from market and you will see what I mean. Once its in standby it goes into deep sleep which I believe is lower than 200? But set it to 1200 min and see if cpuspy logs it as going below that just to see
It will happen on every rom right now since they are all based on the firmware. I really think it saves battery going into that clock mode and if someone comes up with a fix the cpu will have to run at a higher clock rate and battery loss will be significantly higher

I am using Lite'ning rom 1.4 right now, when I press the home button til the screen on take around 0.5 second, is it normally?
I've tried this app,and it did seem work. I'll try to see how about the drain of power.
I was using No Lock and it didn't make any difference. What is really annoying me about this is that some users are seeing the lag and others apparently aren't. The lag on my phone is probably about 1 second. This isn't a really big deal unless this sort of thing annoys you. My iPhone didn't have the lag, my Desire didn't have the lag and I feel a high end phone like this shouldn't have the lag either.

There seems to be nearly as many combinations of symptoms as there are phones. Mine has the same 1s or so lag regardless of how I wake it up. I tried SoftLocker again. Not only does it chew the battery, it was randomly causing my phone not to wake up at all, which then required a reboot. Softlocker has since been uninstalled.
The lag definitely doesn't show itself if the phone is plugged in or if music is playing in the background. Also if the phone has only been asleep for 5 or 10 seconds the lag is generally not there.... but not always. This seems to be inconsistent.
Then there are the fortunate users who aren't seeing the lag at all..... unless of course they are failing to mention that they have something running in the background like the music player that is stopping the phone going into deep sleep.
All I know for sure is that it's a PITA that Samsung needs to address. Given that I've read it was an issue with the S, I'm not holding my breath on that one though.

Don't want to fork/derail the thread, but are you guys experiencing only the "Wake Up Lag" or also the lag when pressing the Home button while unlocked. I see some lag when using the home button to go back to Homescreen 1 for example. In case you folks are seeing lag in both the cases like me, could it be that both have the same underlying cause.
There is this other theory about the bundled Voice Talk app from Vlingo having the shortcut of Home button double tap, which causes any Home button tap to wait until the double tap window before doing its thing. I don't see that mentioned in this thread, but it kind of makes sense for the Home button lag, but perhaps not so much for the Wake lag (at least I could not think of a reason for that to happen). What do you guys think about both these problems?

Well well finally users are reporting this problem, good to see its not only me.
Anyway, I don't think the Phone goes to any underclocked frequency when it goes to sleep. Cause if you can test SetCPU by setting it to 200 MHz then you will notice that in 200 MHz the phone turns itself off, you have to turn it on manually. So the problem is related with firmware definitely. And there are no fortunate users, some users don't take this as a problem, some don't notice it and some notice but doesn't agree, but here or there everyone has the bug. I hope the issue will be fixed in future firmware upgrade.
Regards.

It may seem crazy but...
The delay depends heavily on the lock image you choose for lock screen.
With stock image it's instant, with custom background it slows down significantly.
My theory is that custom image is being resized while low Cpu frequency, it takes a while.

I've just tested that, it's the same no matter what background I use.
Wow..
Seems like the thread I can finally count on! Lots of behavior that I experience as well. I have the home button lag and the wake up lag and it's bugging me.
One thing to note.. The wake up lag is worse when you have an SD card inserted -> This scenario was the same for the SGS1 too. Anyone can confirm this?
I'm using No Lock as personal preference but the lag is always there. All behavior you guys mention (abt headphones plugged in, charging, within 5-10secs) are all being observed.
Eagerly waiting for a fix!
I had lag on my first SGS2, but it was worse that yours, at about 9-10 seconds (that's no exaggeration) plus high battery drain (Only getting about 6-7 hours battery at normal use). Went and got a new S2, no lag, and battery lasts 36 hours now.
It may not be the case with yours that its faulty, but I think I fixed the first SGS2 by flashing a newer rom, then doing hard reset and clearing cache's. I now have 2 shiny new SGS2's working as normal.

I did flash a newer ROM, but didn't do a hard reset.. all my apps were intact. Perhaps I will spend sometime on it this weekend. By the way, which ROM did you flash on your first SGS2 that fixed the problem?
Also, I tried SoftLocker and it works!! The only downside is the battery life. I loose about 4-5% per hour while I was asleep. That bring me to say that the delay is not caused by the voice input function, but rather due to the device going into deep sleep (which may be normal). But it's the waking up that's taking long.
Still seeking for more ideas...

Yes, I found that SoftLocker is not really a solution because of the battery drain and some other bugs it introduced.
Anyone who is experiencing this lag should be contacting Samsung. I contacted Samsung Australia and they told me they had not heard of the problem. If everyone who is experiencing the problem reported it to Samsung, I think there may be a far better chance of a fix. Anyone who is annoyed by this bug, please email Samsung via the link on their website. If they are flooded with complaints they "may" act and provide a fix.
Hello!
Guys it has been a week since I bought my ACE.
Since then it has itself turned off automatically twice.
Once, I was playing Grave Defense HD (Free version), I left it on for 15 minutes, came back, and the phone was off, and didn't turn it until I reinserted the battery.
I thought that may be it was because of too much load on the processor or the memory or battery.
Second time the phone was just lying with nothing ON, I picked up to use, but it was OFF again.
I haven't installed any update so far, so whatever the problem is, it has been there on its own.
Please help.
Also I have noticed that the battery has serious issues, like it wipes out in an entire day if used normally also if i is almost out of juice and you plug it in for just 5 minutes and then plug out, it displays that the battery is almost Full. I mentioning this battery problem to make sure that it is not just me, otherwise this might be the reason for automatic turn-offs.
Thanks.

My brother bought a second hand SGS2 (I9100), and it has some weird glitch affecting the battery reading.
Even though the phone is fully charged, when the phone goes to standby mode (sleep), after a few minutes, or seconds, it suddenly "thinks" that the battery is not charged, so it turns itself off. When you turn it back on, is says we need to charge it, but after 15 to 30 seconds, it reads the battery properly, and goes back to the right battery %. If the phone doesn't go to standby, then the battery glitch doesn't affect, it doesn't say it is not charged, and it can be used with no problems for hours.
I've reset it to factory reset, but it hasn't solve the bug. We have tried also changing for another battery (I have one as well), but is not that, the battery is perfect (both of them). We changed the ROM a couple times, also changed the Kernel and root it, but the issue does not go away.
Can anybody tell me with the info provided if it is a hardware issue (hope not) or if it can be on the software? I've searched the forums but didn't find others with the same issue.
Thanks in advance for any help you can give us to figure it out.

Dont wanna sound rude or anything, but s2 is still not a cheap phone (for most of people atleaset) , meaning,
when ur buying smartphone 2nd hand, the seller will have to agree on me turning on phone, playing with it for 20 mins, check everything and so on..
Display, RAM, everything, meet somewhere where is wireless so you can download android system tester off market etc etc
Because i am almost sure this is HW problem mate. I suggest you call him right away, and hope he still has the same number

Not rude at all! My brother review the phone, but didn't seem to have any issue at the beggining, started to fail like a week later.
We can return the phone at any time, is just that they don't have another one to give us right away, and most likely they'll take it for a review before we can get either a refund or another unit, so we wanted to explore all the options ourselves first.
I'm sure he'll be returning the phone soon as we pretty much ran out of options.

Thanks a lot Jokesy, you have been very helpful as I followed the thread and it is the exact same issue.
After a few days, the problem got even whorse as everytime is even harder to turn it on because it reads low battery. We can only turn it on, most of the time, through Recovery, as the key combination for Download Mode doesn't even respond. Sometimes doesn't respond at all. We just need to turn it on one more time to flash the stock ROM to return it.

This is the 3rd time this has happened to me. If the tablet shuts itself off because of battery is 0% then it will get stuck @ Samsung screen on boot (after charging). I had to factory reset it the first time, the 2nd time got away with clearing the cache. This time looks like its another factory reset. Anyone else having/had this issue? This is a stock device with no mods at all. Any help would be appreciated.
Any reason you are running it down to 0% or is that part of the problem?

As a general rule, Lithium Ion batteries dont like to be completely discharged. I would.put it on the charger and just leave it there for a bit and it should be ok.
That aside, you can adjust some settings so that it doesn't run dead. Set your Wi-Fi not to stay connected when its off. Another very useful app is Greenify. I took it one step further and installed the app called Automate. Then I created a flow that turns off wifi and BY, and then triggers Greenify's hibernate mode, and then it turns the screen off. I put a shortcut to this flow on my home screen so I can trigger it when I'm not going to use the tablet for a while. Usually my tablet will loose 5% max over 24 hours of non-use.

I agree but at this point I am just trying to get my device to boot with out factory reset.
AQF5 build came out today for Korea, trying that now. The way they are increasing the build numbers, hopefully they are actually fixing something. Interestingly this had a modem file too though the SM-T820 is wifi only.
http://updato.com/firmware-archive-s...3AFA163EE8F90B
No dice still with AQF5 KOO firmware today, I officially give up. Likely a hw issue , only reason they have not addressed it across 6 firmware updates. Too bad since the tablet is very decent otherwise. Unlikely this will ever get fixed at this point since this is not a Note 7 type headline grabber. Time to find an used S2 to replace the one I sold or wait on something else.My S3 is going back tomorrow.
Yeah I had to factor reset it again to get it to boot. Its a nice device other than that.
