[Q] Strange behavior while charging - T-Mobile Samsung Galaxy S II SGH-T989

My issue does not seem to be specific to any one rom, I have flashed nearly all of them. When I try to use my phone while it is charging, the touch screen is slow to respond or extremely laggy. I use the stock USB cable and AC adapter.
Does anyone else experience this?

Hi. Did you do a search 1st ? No, because this has been answered before. Next time don't be afraid to go thru some pages and do a search before posting a redundant question. Thanks.

I did try to do a search, but the search field disappears when I try to use it on my tablet. Ever time the android keyboard comes up, the search field goes away. Could you kindly direct me to the correct post.

I finally was able to search the threads when I switched to my phone.(it had charged enough to unplug out and use) From what I gather, it is a result of a built in feature on this Samsung phone used to eliminate "ghost touches"
This doesn't help the fact that it is annoying and counterproductive when I am trying to read xda posts while at work.

people can be meanies on here. xda search isn't the greatest thing. But it could be that the charger is faulty. Probably need a new one. T-mobile could supply you one through warranty for free. Try to ask for the cable and battery too while you're at it. they're all covered.

It's not super clear what the issue is. Some people say that the issue goes away when not using the stock Samsung charger, some say the issue is a grounding issue. I personally have experienced this issue in the lock screen and it'll take like 5 tries to unlock but outside of the lock screen I don't have issues with general usage. Rest assured it's not a faulty phone, or even a faulty charger.

Quick question after permrooting with visionary

Hey everyone! I'm new here in a way with this being my first post but have been on xda for months lurking the forums and absorbing information having to do with samsung vibrant to now the g2. Before i ask my question I must say this website is the best website i have EVER got any sort of information about phones and everything and anything you can possibly do with them! And want to say thank you to EVERYONE who makes it possibly! Now for the question and some sort of problem. I permrooted my g2 last night and everything to my knowledge has gone well. I also even turned S-Off and now i can boot into recovery no problem. The only problem I seem to have and can't find the solution through google or on the forums is that when I have my phone completely powered down and put it on the charger after it's powered down the phone will just automatically boot into recovery without me even doing it. It says "go back to end debugging" when I go to check the key test and I really don't understand what and where it's talking about debugging when I just have my phone plugged into a outlet. If anyone has this problem or maybe has solved this with some sort of solution your insight would be greatly appreciated.

its specifically within cwm, even other phones are experiencing the same issues with cwm
So no possible fix or something like that to keep it from happening? I mean I usually shut my phone at night just to give it a rest and to charge but now I can't because of recovery. Does everyone who permroots their phone experience this or only some?

No possible fix I've seen as of yet. I'm sure many people do witness this happening, but I personally never turn my phone off at night just to charge it. I hear its not good for batteries to over charge them again and again. I usually charge mine in morning and throughout the day and leave it be over night.

There's no such thing as over charging Lithium Ion battery lol. You can plug it in 24/7 and be safe. It is a myth.

Well I guess I'll just have to wait and deal with it until a fix hopefully comes out for it. And ya I never heard of overcharging lithium ion batteries...but idk. Now while waiting for a fix for that little bug i'd like a flashable overclock

Meh. I've had a bunch of people tell me they had to buy new batteries from leaving their phone charging all night and a few reps have told me not to do it. I think specifically that was when I had my BlackBerry. That's only reason I thought that. =P Either way, thanks for the info. Learning is great. =]
Well i can tell you i had an adp1 and my wife had a g1 she would charge throughout the day and i only charged at night. While we both had to get new bats because of swelling hers died a lot faster then mine. So i say charge when its dead at night is better but thats just mho.

[Q] Extremely Slow Screen Wake Up Delay?

Just picked up the phone today and noticed a long delay between pressing the power button and the screen waking up. When it is plugged in there is no delay at all. The delay occurs whenever the phone is disconnected from a power source. It is about a 2 second delay. Is anyone else experiencing this? Best Buy didn't have another unit and the Sprint store was useless and wouldn't unplug their demo unit to compare.
I saw a thread concerning the standard Galaxy S II, but nothing Epic 4G Touch specific.
Thanks.
*update*
Just to make things perfectly clear, here is a video of the delay time:
http://www.youtube.com/watch?v=vqJc_nYuwac
*older update*
Downloaded Soft Locker Free and it allows the phone to instantly wake with no delay by bypassing a deep sleep mode. I'm unsure about how detrimental this is to the battery, but at least it's a fix. I'd still like to know if all Epic Touch phones have the wake up lag, though.
mine is doing this too.. are you using a SD Card wallpaper? I am. not sure if thats affecting things.
I have not noticed any delays on mine.
I have noticed this as well. I'm using a stock wallpaper.

You shouldn't do that, it will be detrimental to your battery. Deep sleep mode means that the processor is technically off, provided the phone doesn't have any tasks to run while the screen is off.
Its perfectly natural for your phone to wake up immediately when plugged in, because that's how samsung designed the galaxy's. No need to deep sleep when the phone's getting a charge.
By restricting your phone from sleeping (affectionately referred to as wake lock),your forcing your processor to run for nothing, most likely at 200mhz. When it's all said and done, I estimate you'll end up shaving off about 5 hours of battery life. Not worth it to me, just learn to deal with 1 sec it takes to wake up the phone.
On a lighter note, I find it amusing that you've installed an app that now makes the phone do something that is commonly known as a bug and a lot of people spend their time trying to squash. Lol.

Thanks for all the responses. My past Android phones (Evo and Evo 3D) didn't have any delay whatsoever, which is the origin of the original post. The power of the Galaxy S2 phones is pretty much legendary, which is why I'm surprised about this power saving feature. Reviews boast quick boot times, but I would argue that a regular wake time is much more useful and realistic to have. I do understand the basic premise that a powerful phone consumes more battery, but that didn't make any other dual core phone I've seen require this precaution.
Therefore, why is it that others forego this feature if it ultimately saves so much battery that Samsung has made it a default feature on their latest phones?
Updated the OP with a video. Please view and tell me if this is the norm.
I watched the video, mine is not that slow delay.

Funny how mine has all my apps on it... (over 40) and a **** load of music... And for the life of me I cant get it go lag like that.... I had a refurbished evo 3d that did that... I called sprint.after factory reset and.a few battery pulls... Id just return it.
roms dont fix all bugs let alone one random wake lag problem and the op may have to deal with it as most of us dont have lag like that...
@op if you got it from a store id bring it in.... if a rep says its suppose to do that.... Tell them your older android phone didnt do it... Then ask to speak to a manager
Sent from my SPH-D710 using XDA App
Yeah... I had a feeling it was worse than it should have been. Though it's true a custom ROM could fix it, it would probably implement a fix similar to Soft Locker (which is obviously shunned for its battery draining ability). Also, I'd much rather have a device in proper working order to begin with. The Best Buy I got it from only had 2 on launch day, so here's hoping I find one that has it in stock.
Thanks for all the replies.
My delay is similar to the video. How does everyone else compare after seeing the video?

Most likely something that you have installed on your phone isnt liking ICS. Hard to narrow down if you have alot of apps installed.
I have had mine for 6 days now and not had a single Sleep of Death and I havent seen too many comments about it so I dont think its a problem with ICS directly.

I had exactly the same thing last night, I even made my own thread
http://forum.xda-developers.com/showthread.php?t=1360847&page=2
I even wrote a simple app for logging the battery temperature and time, so I'll leave it on next night and I'll see what happens. Because I'm pretty sure my phone switched off due to overheating, as it was really,really hot in the morning, after I switched it on the battery was at 46C.
I'm afraid I can confirm that I have experienced the same "sleep of death" problem twice now. I can't remember what I was doing the first time, but the second time I was only browsing and I know I didn't have any apps installed because I had previously reset my phone. I've only had the phone for two days now and if it does it again I might have to send it back.
I expected a glitch or two, but with the volume bug and other annoying things like the lack of flash and poor camera quality, I'm beginning to regret my purchase. Although I love the ice cream sandwich experience, I'm now thinking of getting the Galaxy Note instead, and waiting for ICS to arrive on that next year. At least then I will be able to watch iPlayer in the meantime.
Mines done it about 4 times. Pre installed Movie maker seems to induce it.

Had a sleep of death for the first time yesterday - the only "different" thing I did during the day was use spotify so there maybe something in that!
Same again last night, woke up this morning and phone was on but wouldn't wake. Notification light was on solid. Was plugged in at wall all night, didn't seem too warm when I held it.
Time to start debugging I guess
I've had this issue twice too.
I do not have spotify installed, and the phone was NOT hot at all. Not even warm!
I was just in gmail, sent a mail, then pressed the home button, and black.... gone.
Had to pull battery.
Thinking of having phone replaced by Handtec. I know this is probably a software glitch, but the volume bug, and the fact my unit was one that handtec had "tested" etc, I might just ask for a brand new one from the new flashed batch due next week.
Wtf! Just how wide spread is this??? Seems like too many people are having this issue.
Phone hasn't even arrived yet and I'm already starting to question my purchase.
1 more bug and im cancelling my order !
Well, it's the first device with ICS so I expect there will be a few bugs in the future which will need to be fixed. That's the reason why I'll go for the Nexus ... it's a nice piece of hardware but even more important is that it will be the device which gets the fixes first.
Did anyone check to see if you've had an OTA for the volume ghost fix and this problem has spawned instead? Seems like a fairly new problem if you have followed the forum.

Are you using the original charger and cable? I had the same issue and it started working after I finally pulled them out of the box.
To answer your initial statement, anything that doesn't fall under development would go on the general forum.
That being said, I remember this issue being brought up by lots of members at the beginning. So, a search should give you some answers. I think rooting and trying out one of the great roms currently available here is the best way to go IMO. I personally recommend Juggernaut

Sleep of Death while charging [Solved]

Hi all, there is a small app I wrote that will solve the problem with the Nexus 4 dying while connected to the charger overnight. It's completely free (no ads also) and can be downloaded from Google's Play Store. No ROOT required, works on completely stock phones. I tried it on my phone and haven't had a SoD for 5 nights (I used to have it almost every night). Also a colleague of mine used to suffer from this and the app solved his problem too.
The app basically puts a wakelock on the phone that will allow for the backlight to go off, so the screen doesn't age, but will prevent the CPU from sleeping while charging. Once external power is disconnected, the wakelock is released and so the app does NOT consume any battery (while in automatic mode).
So if you happen to have the same issue, feel free to try the app and save yourself the troubles of returning otherwise a perfectly good phone.
P.S. I have just uploaded the app, so if it's not yet visible for your country, please try again in a few hours.
Update: Now the application checks if the power is connected when the device is powered on, because otherwise the wakelock was not acquired when powering on with charger connected. Unfortunately this requires a new permission ("RECEIVE_BOOT_COMPLETED") and the application to be opened after updating for the receiver to be registered by the system. Also I added a notification in the status bar while the application is running. You have to enable it in the settings if you want it displayed.
will test it an report back

its NOT a hardware issue, software related. was VERY common on android 4.1.2, especially on the galaxy nexus. it happened to all the different nexus, nut the gnex suffered the most. 4.2.2 fixed the issue, and google did say it was a real issue. it still happens, but much rarer than before. btw, there are a few apps that bring it on for the nexus 4, one known app to bring on sod is ezekeels experience app. chew on that.

it creates a wakelock preventing the device from (deep)sleeping. its not really a solution, is just a work around for the problem.

Exactly. But it listens for charger connected / disconnected to acquire / release the wakelock and thus consumes energy only while the device is connected to an external power source (you can see it starting and stopping in the manage applications settings menu). True, that's not a "solution" (that's Google's job), but it doesn't interfere with the normal device operation and does not require any user interaction other than enabling it on install, so until there is a real solution it's the best I can come up with .

That's what i thought. Fine then, as long as the wakelocks do not continue when phone is not being charged.

Way to show your technical prowess :laugh: Anyone that RMA's a phone for this issue ought to be shot in the knees, and given a Galaxy S1 to replace their Nexus, as they don't deserve to own one.
It's a software issue... on a DEVELOPER PHONE... or did everyone miss the fact that the Nexus line of products is supposed to be for devs' to buy and use to test new software/hardware configurations on.
edit---> Oh, and +1 to OP, good job creating a workaround!
I have the same problem.... I test this app and hope functionally .... I

Definitely software. My problems started happening after 4.2.2 updates. I wish I paid attention to what kernel version it began on.
Anyway, I haven't had an issue since using this app. So about two days.
Thanks a million tkolev! I can use this as my alarm again.

I'm glad it helps you too!
May I ask anyone that tries it to go back to the Play Store in a few days and rate the app to increase it's visibility and possibly help others to stumble upon it while searching for a solution. Thanks!

Sure thing, its the least one could do .
Also could you explain, to the best of your knowledge, why the sod's occur when in sleep mode?

I have no idea. My first thought was to create a Daydream as those seemed to help too, but I could not turn the display off (you can only control the brightness but that would still keep the backlight on). The strange thing is that while "dead" something in the system is still working because an application that shows the battery percentage by changing the color of the notification LED was still working. Even after I had unplugged the phone. I know that it might sound like a heresy here, but I don't want to use custom ROMs (I use my Nexus for development and keeping it stock for compatibility is a must), so trying different kernels and ROMs was a no-go.

So this was happening to you while completely stock, minus root?
Does this always happen you? Even while on 4.2 .1?

I only recently got my hands on the Nexus 4. I live in Bulgaria and Google does not sell devices here, so I had to either wait for any of my colleagues to go to the US on a business trip while the device was in stock or pay more than 150% to buy one from a local reseller. I've been on 4.2.2 since day one. No custom ROMs, no root, not even unlocked boot loader.

I see. The reason I'm asking is it didn't start happening to me until 4.2.2, but not sure what kernel revision it started on.
Just trying to establish a timeline.
Still the app is a life saver

With all due respect (honestly) and not sarcastically- if this was the case wouldn't the phone come rooted already and in developer mode? I am pretty sure it is being marketed as the flagship "pure google" phone and not only for developers. That said it is easily understandable as to why this is a frustrating issue.
To the OP: A million thanks! I hope this app does the trick- regardless thanks for your efforts and making this community what it is.
