[Q] Black Screen While Charging - T-Mobile Samsung Galaxy S II SGH-T989

First off in case I have created a thread that already exists I'd like to say sorry and can you please direct me to said thread as I couldn't find it in my search.
When I plug my phone into the charger there is a longer than usual delay before it switches from discharge to charge. While still the phone is plugged in when I shut the screen off it stays off when I press the lock/power button but the lights under the hard keys light up and the touchscreen becomes active (I know this because I can hear the lock screen unlock when I swipe it). Everything on the phone comes to life except for the display its self. I am just wondering if someone out there knows or has had this happen to them and could tell me if it is a hardware or software issue and what I can do to fix it.
Thanks and again sorry if i have reposted something.

If your rooted flash another rom. If your running a custom rom wich one are you running. Something similar happens to me on the 4.2.1 rom's but only when using a usb cord to cpu to charge.

[Q] Screen wont turn on after it turns off. ATT Tilt 2

Everytime I boot my phone up, it works fine up until when the screen goes into sleep mode. Once it goes into sleep mode I cannot turn the screen back on, it stays black. The keyboard, end and answer key lights show up when I press the power button but the screen just stays black no matter what button I press.
I end up having to either take the battery out or using the stick to press the reset button on the side in order to get the phone to where I can see the screen again. I have adjusted the settings to where the screen doesnt go into sleep mode and the screen just stays on but that drains my battery. I want to be able to have my screen go off so I can save power but if it goes off it wont come on again until I reboot.
I have done a hard reset. This problem started happening to me when I started using the Energy Rom but I've even flashed different Roms and the problem still exist.
Somebody please tell me what's wrong! I need help! This is a big annoying problem to have. Thanks.
is this problem occurring when you slide the keyboard out?
i had the t-mobile touch pro2 with this problem.
the screen would die when the keyboard was out and not come back.
if this is the case, what i did was...
well. obviously not open the keyboard fully.
but if i accidentally had.
instead of pulling out the battery, i waited...
till the screen 'naturally' went to sleep.
than i would pull out the stylus or press power button
and the screen would come on.

Yes the problem still exist even when I slide the keyboard out. Once the screen goes off, that's it....pressing the power button to get it out of sleep mode, sliding the keyboard, I press all buttons and nothing works. The only thing that "works" to get the screen back on is removing the battery or using the stylus to press the reset button.
When sliding the keyboard out the keys light up but the screen doesn't come on, also pressing the power button lights up the end and answer keys without the screen coming on.

so. whenever the screen goes out, period, you cant get it back?
or the screen goes out and cant get it back once you slide the keyboard out?
if it is only when sliding out the keyboard...
try not opening the keyboard fully on the right side.
on my rhodium, after that point, the screen goes out.

Yes, period. Also, you know when you put your face to the phone during a call and the screen goes off so your face wont press anything on the screen? It doesn't come back on from that either once I end the phone call, it just stays black. I'm assuming you don't have any other suggestions. This Sucks

This has to be a software issue but I don't know where to start. I'm surprised nobody else has encountered this problem. I've grown frustrated of this issue because I don't understand why it's doing this. I have had the phone for almost 6 months only dropping it once 4 months ago and it wasn't a strong damaging drop that would affect anything inside. I guess I'll just have to go last resort and call warranty to swap the phone out. Thanks for the help.
Same problem

My phone also dos not come back on, when I put it in out the sreen with the power button on top, or when the phone goes to sleep. Nothing can put it back on(opening te keyboard, pulling out the stylis, presing the answer-, windows-, back- and end button). I and up using a music players too keep the phone busy what's makes it operational. Cant really remember when this started happening exactly. My phone is at the moment loaded with a standard ROM. I used too have a custom ROM.
My TP2 does this too, although I only encounter the problem sometimes when someone calls. I answer and put the phone next to my ear, the screen goes black as it should and the phone just dies. I can't hear what the other person is saying and the screen wont turn on anymore. I have to take out the battery to reboot.
set light sensor to manual in settings. You have some bad or fragmented code causing the problem. Pretty common actually, many different reasons, but usually either a bad light or proximity sensor or software issue. Setting the sensor to manual should do it, if not, hard reset and allow the phone to fully set up before touching it, to allow full customization process to complete. Search my posts on SOD (sleep of death) for more information.
Funny this was brought up. Now im worried I just dropped 250.00 and have a new one coming.
Mine started with the ear piece quit working. couldnt hear anything except on speaker.
Anyway I started having the screen issue over a month ago, only way to get it back was soft reset with the stylus. Also when the screen was lit, I couldn't hit the power button to turn the screen off. At times the screen would be on 24/7 and I just dealt with it. The times when it decieded to go to sleep was when I needed the soft reset. Well long story short I forgot my charger one day at work and the battery died. after pressing the power button for hours with no response, moving the screen in all diffrent directions as I pressed the button.It came on once after hrs of messing with it. Well today it died again and I am fed up with it so out came the tools. Once I opened it up I noticed the ribbon that feeds the screen from the mother board was worn and torn. the ribbon slides everytime the keyboard is slid out and it rubs on both sides of the phone. I thought maybe mine was just a fluke and was installed wrong considering the phone being 10 months old but now I read this and see maybe its a common problem. The cheapest I could find the Ribbon was 56.00 so I didnt want to chance it not being the issue.

[Q] disabling the turning on when charged

Is there an option to stop it turning itself on when the chargers pluged in and unpluged?
turn on to android or recovery?
the phone screen turns on when i plug and unplug the charger, would just like to disable this if possible
the phone is on, screen off.
and you plug it to charger and the screen is on?
if it is, go to:
menu-settings-applications-development.
see the box of the "stay awake"
yep that what im on about, but the box is unticked, and ticking it makes no difference?
hmm, you can try mark it, restart the phone, and unmark and restart.
done, but still the same?

That would stop the screen to turn off while charging, not prevent it from turning on. I think there is no way to stop this.
if he set a time out for the screen, the scree supposed to go off.
in this position, the next thing is the "stay awake".
when stay awake is marked, the screen stay on when he connected to charger.
if the stay awake is not marked, the screen need to proceed like he set in the time out.
which rom do you have?
if you have a custom one, you can ask the creator.
you can use the power button to close the screen manually.

basically, when i put the phone from my pocket into my car dock thats hard wired, it turns the screen on. Simple solution press the power button to turn it off again, same when i remove the phone from the dock it turns the screen on, again the power button sorts it, but its a PITA !
never had this issue with previous HTCs, none being android tho?

fair comment , just reread your op and realised it's not the recovery whilst charging issue your having, but phone turning on when plugging in, yes?
yep, not doing no fancy flashing roms or rooting stuff just yet, just simple stuff like trying to get the phone to charge without it automatically waking up the screen
I'm having the same problem. I would like to try the battery calibration trick i found here but it requires me to charge my phone while turned off. But whenever i plug in the charger my DHD turns on and goes into CWM menu screen. Is there a fix for this?

You are having a different problem. He is taking about how the phone wakes up when it is on and you unplug it from the charger.
I have the same problem but not sure if its a problem or a feature.

[FIXED] STOCK HTC ONE - Screen not turning on, phone running hot, battery draining...

Hey guys... so I've noticed my phone acting a bit funky after the latest KitKat update. Just a bit of freezing and lagging, but my 32GB of space was also full. So I did a complete wipe and factory reset and started from scratch. At first everything was great (about a week or two). Then the past day or two I've noticed the below issues...
1. While at work, I keep the phone plugged into my computer via USB with Internet Pass-Through and WiFi turned on. I have it setup this way so I can use the computers internet and trickle charge the phone at the same time. But when I leave my desk I simply unplug my phone and it connects to my works WiFi while I'm walking around the office. I get back to my desk I plug it back in.
Problem: I've noticed lately that I'll pick up my phone and it's HOT to the touch. As well as the battery percentage is actually dropping even though it's plugged in.
2. At night when I go to sleep, using the HTC Charger and Cable that came with the phone I'll plug it in next to my bedside and let it charge.
Problem: I'll wake up in the morning, hit the power button to light up the screen and nothing happens. The Home Key and the Back Arrow (are these what everyone refers to as the "soft keys"?) are lit up but the screen will not turn on. To get the screen on, I have to HOLD the power button down, the screen then lights up with the Restart menu showing (and yes I've restarted it many times in hopes of fixing this issue) and I have to tap outside that box (on my wallpaper or wherever) and the menu will go away and my screen is back up like normal. However as soon as I tap the power button to turn off the screen (not the phone) and tap the power button again, nothing happens except the bottom keys being lit up. It's an ugly circle.
I have noticed a few times when holding the power button to bring up the screen/reset menu, sometimes the screen/reset menu will not turn on, but the home and back arrow keys on the bottom will flash a few times.
Any ideas guys? Loved this phone up until now
So after 200+ views and no comments I'd just like to add that I think I found the fix for this. I spoke with a few different HTC techs and tried multiple things before having to ship it out to them and right before doing so they had me reset what they termed the "Charging Logic"
To reset the Charging Logic
1. Power phone completely off
2. Once powered off, hold the Volume UP, Volume Down, and Power buttons for 2 minutes (my fingertips were sore afterwards LOL)
3. You should get a white background with the green HTC logo turn on/off multiple times. Almost as if it's trying to reboot...
4. After 2 minutes, let go of the buttons and let it reboot.
DONE!
Since I've done this, I've noticed my battery life extremely improved. My phone is no longer getting crazy hot, and the screen now turns on after an over-night charge!
Hope this helps others!
Does it matter what kind of charge you have on the battery when you do this? This is the first I've ever heard of resetting Charging Logic.

Does it matter what percentage your battery is at and does it work for rooted phones? Do I need to be on the stock Rom/recovery for it to work?

Sorry I'm not familiar enough with the developer side of things to tell you "it's ok" or "not".
What I can say is, the HTC tech never did ask me if my phone was fully charged or what percentage it was at. Which at the time was like 97% if I recall correctly. I am completely stock...
I would imagine this would work for rooted phones and it wouldn't matter what battery percentage but can't guarantee you...
I just wanted to come back in here and update this again. The above fix did not actually fix the phone as the problem came back again eventually. I am now on my third HTC ONE M7 and looks like I'll have to send this one back as well for the same issue.
I have a theory that it's either a problem with the OS or Light Sensor causing the screen not to turn on.
Can a mod take this thread off "fixed"

Help: G3 doesn't power on - Only blue/green notification light blinks :(

The G3 just dropped down on the floor with the circle case. Then It was working some minutes apparently with no problem, until I myself turn the phone off and restart it. Then the device just didn't turn on. The only thing is that the screen is black and the led notification blinking green and blue
when i connect the charger, the red led blinks once and then disappears, then after 30 seconds the red led appears which apparently shows that the phone is charging the battery. Also When I connect the phone to the PC, a sound of connection is heard from PC but the PC doesn't complete the device recognition process as no new device is found.
I tried to make a hard reset, but nothing happens when I press the power and volume down keys. Tried some other tricks with the battery and the hard keys on the phone but no result at all, as the same story just repeats. Does anybody have a solution for the problem? This devise is the only android device I have
Help
Please Help :crying:

Did you do anything else after/during the time that the phone was off? And is there no possibility that you cracked the LCD digitizer? I mean it might sound strange but this is what I had with my old phone. I dropped it, nothing serious but then I put it in my pocket and upon taking it out I noticed the screen not turning on. As stated above, my digitizer was broken and multiple people told me that the digitizer had a small crack which I didn't notice, then when I put it in my pocket I put too much pressure on the digitizer cracking it. The LED-light did work though, and this sounds very similar so my advise going to the store and asking wether they know what the problem might be.
(Hopefully this was helpfull hehe)

If you Don't see the LG splash screen when pressing the power button it seems like a screen or digitizer problem for sure.
BUT;
after you try turning it "on" let it sit a few minutes and see if you can call your self or send a text to see if it makes noise vibrates etc. to confirm a screen problem.
OR
Also you can try putting it into download mode.
Battery pull (don't turn on)
plug USB into phone but not computer
Hold volume down AND then plug usb into computer
if this comes up to a pic of something on the phone it will be software related. to get out of this mode you can do a battery pull.
Remember to always read up on topics and things you are doing. There are guides here on XDA to help you out.
Hope you get your phone working

I didn't do anything special after/during the time the phone was off. I checked the screen very carefully under a lamp. No particular sign of crack. Thank you very much for sharing ur experience.:good:

Hope you fix your phone fast
Yeah... Probably it's a hardware problem. Someone who checked the phone in order to fix it, said that the problem had been with the device board. Even though I was satisfied with the phone, I have found out that the G3 is a sensitive device, as the height of the table from which it dropped down wasn't too much. So always take care of your G3 phone.

confusing screen burn-in/flickering (first post woohoo)

Hello. This is my first thread, I have downloaded maybe hundreds of ROM's from this site, have read thousands of threads and of course bricked a few phones lmao. Now I am here with a REALLY confusing problem. Without further ado, let's dive in. sry for my bad english btw.
I bought a second hand S9 today. The guy whom I bought the device told me, when he turns off the screen of the device by pressing the power button, black and green lines appear when he turns on again, and after a few seconds, when he turns the screen back on by pressing the power button, the problem disappears he told. I think he said there is a problem in the part called screen flex. (I ain't sure what that is, I need info about that too.) Sorry if you're confused this far, cuz more is coming thru
I got a very useful APK file named "OLED/AMOLED Saver" and installed it on my device, it worked really well and the lines were almost invisible anymore. After a few hours of use, what I noticed was even more confusing. I activated the AoD (Always on Display) feature, coincidentally, while testing the screen, when I locked the device by pressing the power button and the clock appeared on the AoD screen, when I turned on the screen in that way, I noticed that the screen did not burn in as if it was brand damn new. But if I don't wait for the AoD screen to show up and immediately press the power button again, the screen turns on completely and something really, really terrible appears, a mixture of black and green. Now let's come to my questions, I've blown your mind a lot I think.
1- Can anyone explain what's going on here?
2- Is the problem in the screen flex or is it purely software? (AoD thing)
3-Is there anyone who has experienced this and was able to completely solve the problem?
Thank you for spending your precious time. Hope I get a solution..
Hello, I have same problem with my old S9, it seems that is fully hardware issue, as a workaround you can set full brightness - it causes this issue to appear less frequently and another option is cooling down the phone - when display is black/green just lock the screen and put your phone to the freezer for a while - it will work properly until it heats again
Its something about an update made by Samsung https://eu.community.samsung.com/t5...t-bars-black-screen-issue/td-p/1745470/page/4
