My galaxy S3 is showing a very weird problem. I was using the phone and before reaching home the battery when completely flat. When I arrived home and plugged the phone to the wall charger the screen remains dark, black. Now the battery is full charged (green light) but the screen remains to the same estate. When someone calls me the phone rings. When I plug it to the computer I can see the files inside the different drives. I reinstalled the OS that is 4.3 but still same problem. I didn't drop the phone and It didn't have any shock.
That is weird. I am thinking of a dead screen but before going for a chirgucal operation on my beloved phone I wanted to ask if that couldn't be a software problem.
Happy to hear from your experiences.
Boot into download mode, volume down + home then power button. If the screen is dead in download then it is hardware.

never heard this type of problem
try to go into recovery and check if it displays anything
If successful do factory reset
In download mode i can see nothing. That is really weird. I am letting the battery drain completely and i will check. Thank you for your replies
I wanted to upgrade so far what i am getting. The screen while dark, black is reacting to touch actions: for exemple when i lock the phone with the power button i can hear the lock sound;when i unlock with the lide action on the screen, I can hear the unlocking sound. I think that must be a weird system problem. If the screen was broken will it react to such touch actions?
Lide=slide. I can actually take a call with the slide action on the screen. When someone calls me i just have to slide my finder at the proper place on the screen to take the call. I need help please.
Most probably its the hardware. Your LED seems to be ditching you. And yes a bad led can still response to touch despite of being black all the way. Actually it's the digitizer that responds to the touch NOT the LED itself.
In your cas3 so far from your feedback I can say that you are having a bad LED everything else including the digitizer is working well.

Thank you i w
ill try it check it tomorrow. I will try to install another firmware, may be 4.0.4. The one i was using i just installed it 2 days ago.
Hello everyone!
As title says ,my samsung galaxy II (CM12.1 flashed) doesn't give any signs of life.
Here is the story:
I turned off my phone this morning and plugged in charger.After hour i plugged off charger from my phone and tried to turn it on.As it was turning on it got stuck on samsung logo.Afterwards i went into recovery mode and wiped /cache.Everything was fine.Then i went to "factory reset" where problem occured...while it was deleting /data it got stuck.Few minutes later my phone suddenly turned off.After that moment it just won't turn on.I tried to get into recovery and download mode but phone doesn't react.When i plug in charger it doesn't react neither. Battery was at 50% when i tried to turn it on.
Before this, phone was running fine. But recently it was freezing a lot so i had to take off batery and put it back in.
Im not native english speaker so don't get mad on my "perfect" english
I hope someone will help me diagnose the problem
Thank you
Goodmorning.
....the same here..... sadly.
This is what I know regarding that unable to turn phone back on problem, perhaps can solve yours.
We know the S2 i9100 (and maybe the other variants too) has "problem" with battery levels. In my case, it won't surprise when I got (for example) 48% then drops drastically to 3% after reboot. The problem sometimes also occur when I reboot to system from recovery.
Regarding to your problem, try to recharge your S2 until 100% (in this case, phone is off completely), unplug the charger, then turn it on by holding the power button.
If the phone still won't turned on, try this tips as it always working for me. Plug the charger and try to turn the phone on (holding the power button). If the phone just go back to battery indicator screen (sometimes the screen will blinking once), here the problem.
From here, you need to see what kind of battery indicator image shown on the screen. If the image is a battery indicator with round progress inside it (and doesn't change no matter how long you expect to it), you need to press and hold the power button to restart. Repeat this until you got the image with battery indicator with ACTUAL battery level and bar shown. When you see this, unplug your charger, wait until the screen is completely off, then holding the power button to turn on the phone. In my case, this is always work.
If for some reason you never get the correct battery indicator screen after many tries, try to remove the battery off, wait for at least 15 seconds, put it back on, then try the procedure again.
Hope that help.
Hello, friends
Out of the blue, my S6 Edge tried to restart, but got stuck in a loop at the Samsung Logo. One or two times it went to "insert pin" and then restarted again. I tried to Force Restart and it didn't solve the problem.
After a few tries, I managed to wipe the cache partition. Now it's simply bricked with a black screen and a Solid White LED. I can't restart it, enter download mode or safe mode or anything. Odin doesn't recognize it at all. Is there anything I could try?
The phone is not rooted.

Thank you! Tried it. Doesn't work. It's beyond my understading why would it behave this way after I managed to clear the cache. At least before that it went into download mode or safe mode. I still suspect a software issue.

So vol down + home + power will not get you to download mode?
How about recovery? Vol up + home + power?
This happened to me before and the way i got out of it was hold only vol down + power as soon as the screen went off completely (no led lit) switch to download mode combo.
Tried both of the commands. They didn't work. I will let it drain the battery completely and then see what happens.

reminds me of the bad emmc memory like the note 4s had.
some times completly letting the battery drain can fix it being "stuck". then recharge for 20 min or so then trying to turn on.
if u plug it into pc does it reconize anything in device manager
even unknown device or descriptor failed anythiing at all?
This morning the LED was off, so I tried to recharge it. Nothing happens. Also, the PC doesn't detect it at all. I think it's safe to assume I need a new phone. Too bad...at least if I was able to recover the data on this.

now one last sollution is to try buying a cheap battery my note 5 had a issue it shut of one day and wouldnt do nothing i understand ures was blinkik and trying at least
so its a leap but last resort
same problem here started over a week ago - samsung S6: black screen, constant white led. tried all variations of resetting with buttons. over a year ago i replaced the battery, and its been fine since. when this no boot issued happened i also tried changing the battery to a known good one. on inserting a battery and then pressing the power button the indicator led will go to green for less than a second before changing to constant white, and it stays that way no matter what until the battery is drained or the battery is removed. Strange thing is there is no information from samsung on what this behaviour means, but I've come across dozens of other S6 owners on the web with the same problem, so this is obviously diagnostic behaviour designed by samsung - but no info from samsung. the phone has never been damaged or watered or rooted so I'm at a loss.
Confirmed diagnostics:
The phone will respond to the power button and attempt to turn on
The phone will charge a battery, so the charging circuits and battery circuits are working.
The phone does not get picked up by a Windows 10 PC with Kies installed in any state - other samsung phones get picked up no problem.
Same here
I have the same symptoms. When I hild the vol up+home+pwr I get a green let for 1/2 sec then white. No other combinations do a thing. I swapped the battery for a new one. No luck.
Mine started a few days ago. The phone was 50% charge and i plugged it in for two hours. Came back and it had a solid red led. After a few hours the red light went off. It was then 100% unresponsive. I then took it apart and disconnected the battery. When I reconnected it, it started to do the white let thing described above

I have one that behaves exactly the same I changed the battery and didn't make any difference. my next step is to replace power management chip. I'll let you know.
Any luck on this?
Mine has been like this for a couple months, kind of gave up on it, but decided to give it a go again!
Same problem here, just happend after switching the battery. Anyone have solved this?
I found a kinda solution, plug your charger in and charge past 30% then unplug charger. then use just vol down and power button for 7-10 seconds, after 7-10 seconds just release the power button while still holding vol down button until you see samsung logo, you can tell if you did it wrong by the solid led being back on, repeat until success, once you have it on do NOT press the power button or it will RESET back to solid led/black screen.
I have the same problem with my s6 active and similar story to dbeeheim. Has anyone fixed this? And can anyone confirm that enzo13's solution works?
Much thanks in advance!!
i have same problem!
Suddenly my S6 dead, battery was ~80%, no charge
yesterday i try to change battery, after that if push power button, LED small light comes but in white with purple, then stuck. (it's small Notifications LED)
and i chnge the screen, but no more than white/prople LED.
(no any thing on screen, always black..)
what is the problem?
i think it's battery because it last month didn't work good, and it's old 3years battery.. but no idea..
Hello guys my Samsung S6 sm-g920f has the solid white led and black screen. Really no fixes?
thank you
Same issue
I have the exact same issue. My Galaxy S6 Edge (G925F) suddenly died and won't get past the 'Galaxy S6 Edge Powered by Android' screen.
I am unable to reach the recovery options. I've tried flashing two different stock ROMs with Odin which succeed but without successfully turning on my phone. I've also tried flashing TWRP with success in Odin but it won't get past the 'Powered by Android' screen before turning off after +-4 seconds. The white LED is on even when the screen is black.
Just had this same issue, my battery died and I forgot to charge my phone overnight, woke up and it would not turn on, black screen. I did manage to replace the battery and do several diagnostic tests on it. My battery was receiving about half the power output it should be (this is normal it's a 4.5yo phone) and when I replaced the battery with a new one, it did not turn on. With wireless charging I can tell I am receiving a charge and with standard I can not. The screen does not indicate it is charging with either method but my wireless charging pad lights up indicating my phone is being charged. I think it may be the processor or screen itself. This really sucks because I lost all my data on my phone and data recovery can be over $500
Hi, 2 weeks ago I plugged a faulty charger into the phone (while off) and after that it did not turn on anymore, no LED, no recovery, no download mode. It did not charge too. I thought it was a battery problem, I replaced it with a new one and now when I push the power key I have a stable white LED (it turns on some seconds later than normally), a black screen and CPU is overheating a lot (it's hot in a minute only) . I tried to boot it in recovery mode and download mode again, with no different result.
I think some components damaged when I plugged the faulty charger, and now the phone is not able to boot anymore.
Do you agree? Any idea? Any suggestions?
Thank you

Hi there,
Over the years i've done several smart phone repairs, screen replacements, batteries, new cases etc. All of them without any problems. A Few days ago a friend asked me to replace the case and screen of a Huawei P20 lite. Everything went fairly smooth, however after i finished replacing the parts and put the phone back together it does not turn on completely, only the charge light turns red and the phone is vibrating non stop while on charger.
Note: The phone has not been used +- 4 months before repair. When i remove the charger the phone dies again. Sometimes when powering up, the boot animation starts (max 2 sec) but then the screen goes black again (vibrating continues and charging led stays on). The battery was a real pain to get out, so it took some light bending to get it out. Not sure the battery is causing the issue though.
What i've tried:
- Charge the phone with different chargers/cables for 1 hour +
- Charge from low power charger for 4 hours.
- Leave the phone 2 days and try again
- Took it apart again and put it back together, exact same issue.
- Try to start the phone without battery/screen/camera's and other devices that are not mandatory, same issue persists.
- try to get in recovery etc.. no success.
Could anyone help me how to find the culprit of this issue, im really lost.. Any tips are much appreciated.
Thanks in advance!
check batery by multimeter first and if posible use other for test.
take tooth brush and clean all connectors in phone also.
Did u test screen before asembly it ? it was works ?
