My phone s20 ultra is stuck on this blue screen.. what can i do? Thanks!!

Reboot into download mode and use Odin to reflash the firmware.

Wow, I couldn't tolerate OLED burn in like that.
I lived through CRT monitors and I don't want to go back.

Same, it's funny how things come full circle, isn't it? Screen savers were necessary on CRT displays, but LCD negated this. Plasma never became very popular but was susceptible to burn in too. Now with the advent of OLED displays on just about everything, screen savers and timeouts are even more important.

Turn the phone completely off.
Hold both Volume buttons and plug in the USB cable. It should start in download mode.

it's impossible to turn off the device.. any key combination with or without power cord plugged in, is to no avail. the blue screen is always there.. anyone else?

If you hold down the power button, the device should hard reboot after about 10 seconds. Do this while holding both Volume buttons.

[Q] Please help.phone won't turn on

My phone won't turn on. When I plug it into the charger the notification light and the buttons on the bottom of the phone blink on and off.
I am rooted but not unlocked running the new 4.1 update that I was using fine for hours. If anyone knows what's going on please let me know, thank you

I held down the buttons and nothing happens, if I plug it into a computer the lights don't flash, I get the red light like its charging but if I try to turn it on or get into to recovery I get the lg screen then it goes off and the red light and captive buttons flash again. Is it soft bricked?

possibly. the only thing i can really suggest is to lgnpst back to v9 which wont work because you get stuck at the 4glte screen but with everything re installed you should be able to get into stock recovery to either reapply the update or wipe /data i believe to fix it. im not 100% sure this will work so its a little risky

Where can I get lgnspt? I have been trying to find a link somewhere

It seems I've run into the exact same problem. I was halfway through the update steps (hadn't even actually started the update itself) when my phone decided to just shut off (battery was fully charged and plugged in), and now it won't turn on. At best I can get it into fastboot, but can't go into recovery from there. If I plug it into a wall charger it just bootloops. Everything I've tried so far has led me nowhere.

If the lights are flashing it usually means the phone over heated. The only way I know to reset it is to do a battery pull. I've had to do it several times when using the overclock kernel.

This works perfectly. It's what I had to do. Make sure the phone is completely off, then hold vol down + power + home. When the capacitive buttons light up, release the buttons. It will bot into stock recovery, then do a factory reset. Wala!
This doesn't work for me at all, and I just used LGNPST to reflash v9. If I hold down those buttons, nothing happens. If it's plugged in and I hold them down, after 10-15s the charge light flashes fast (cap buttons don't light up). If I let go, the LG screen comes up for a few seconds and then the phone turns off.
You need to pull the battery. Afterwards itll boot fine
Btw its a known issue with this phone. Overheating causes it among other things

I do not have a problem but just to know for future-if I long press the power button that is equivalent to battery pull? Just asking to learn.

I wish it was that easy, but vol up + vol down while holding the power wont fix it when the lights are flashing like a siren.
You will need a small torx bit screwdriver, a philips screwdriver for the battery cable, and 2 pieces of tape to hold the buttons in place. A guitar pick also works good at seperating the case.

Can't start, can't access recovery or download

Okay. When I put my battery into my phone, the Samsung screen shows up. Then, it restarts, and I don't even make it to the Samsung screen before it restarts again and does the little vibrate it does when it starts. When I try to access recovery, it shows the default recovery screen for a couple of seconds, and then it goes back to what I said earlier. I don't even make it to the download mode screen AT ALL. And when I plug it into the wall, it shows the battery screen for a couple seconds, but then its just back to constant restarts. I have had my current ROM install for a long time now and I just want to flash the stock kernel to my phone. Is there any hope in me being able to get the stock kernel flashed through Odin seeing as that I can't even get to the download screen?
Sounds like a bad power button
Sent from my SGH-T989 using xda app-developers app
Would another sign of a bad power button be that before this happened, my button was SUPER touchy? Like, I would barely lay a finger on it and it would sense it.
I THINK YOU'RE RIGHT. I found a post and some of the signs are: Black screen with intermittent vibrating, unable to enter recovery before phone restarts, unable to enter download mode before restart, phone turns on when battery inserted. Looks like I need to take the phone apart. Thank you for mentioning it could be the power button.

There are a few fixes suggested in the bandaid thread. I think one of them involves banging the button with a rubber eraser. Hopefully one will work for you.

Well. It clicks, but the click isn't as... how do I explain this, as quick and CLICK LIKE? It just feels like there is a bit of resistance and it doesn't do a full intense click lol. If that makes any sense.

[Q] Galaxy Tab S - LED Flashing - Won't turn on

Hi, was wondering if anyone else has/had similar issues?
Got the Galaxy Tab S today and was spending time setting it up. Connected to the PC and charge was at about 57%. Suddenly the window displaying tablet contents on the PC disappeared and the screen went black.
The power button didn't turn the screen back on. I held it down, thinking that it required a hard reset but nothing happened. I disconnected the tablet from my pc and went to use it's dedicated charger. The battery icon came up, stating it was 57% charge, and shortly after the LED light on the back of the tablet started flashing rapidly. I quickly took out the cable.
I've tried holding down the home key, volume down, and power button and nothing happens. I then tried the same and having a finger on the screen. Then I repeated the process again with the cable connected to the charger, and then computer.
No matter what I try, the device won't turn on and the LED keeps flashing repeatedly when connected with usb charging cable. I also tried using another cable.
I'm thinking of phoning up where I got it from tomorrow and asking for a replacement, unless there's something I'm missing here?
Any thoughts would be great, thanks.
My guess would be, you are not pressing the buttons correctly.

That doesn't work either. The only response I get from the tablet is by plugging in the charging cable and then it goes on to display an epileptic inducing light show with the LED constantly flashing on and off

Never seen this problem before. Could be a bad partition making it not boot. Replacement may be your answer as its better to get a new one and be safe.

I've used various tablets before and never encountered any of them not booting at all. The led flashing business is very weird. I'll phone up the store I got it from and ask if I can get a replacement.

[Q] black screen / Screen unresponsive - Sumsung Galaxy Tab S 10.5 (SM-T805)

My tablet Galaxy Tab S 10.5 (SM-T805) screen went black. I can’t see the screen.
Touch also does not seem to work. However it’s on. it is receiving calls and other messages. It is connected to WiFi.
Power button, volume button are working but I can’t power off the device cause I can’t see the screen options.
When I plug in to the charging cable it vibrates but does not show anything on screen.
It didn't drop or hit by anything. i have been using it for 3 months now. it just happened by itself or may be by some update that I don’t know.
Please help how to bring it back to life
GUI crashed. Press Power+Vol up+Home (for approx 20 sec).

Power+voldown+home.
If this does not boot, you could try with usb dongle.
Or full run down to empty battery.
Next chance would require to open it.

It's not bricked so calm down. It just had a cyber stroke. It will be fine just let the power run out and recharge the battery so u can turn it on again. Same thing happened within days for getting mine.
yes... I am waiting for the battery to be completely dead. so far its on...taking calls and sms..I don't howmuch % of batter is left cause I can't see it.
I had the exact same problem once....and i had a hunch that the screen was fine, it turned out it was thankfully....but....im aware that on 100 percent battery in standby it can last a good week or so....i was too impatient...so i ran my fingers around the edge of the backing and slowly was able to pull out the back of tge case and unclip the battery...worked straight away when turned on.
But also what i discovered does reset the tablet forcefully is holding power, vol down and the center button at the same time....try it a few times for a minute each time...if successful you might get a message about being in download mode but then just do the same thing again but imidiatly release your fingers once you see the screen go off from download mode or it will just go bavk into it...good luck m8
Have you tried holding down the power button for awhile, like 30 seconds? This should shut your device off....Then take it from there.

Seriously on my tab right now i just held vol down, power and center button whilst on and after 25 seconds screen went black then gave the "are you sure you want to enter download mode." Then i tapped vol up......t805 as well.
Battery completely empty.. tab S turned off, i plugged in the charging cable (1 ) battery meter does not appear (2) Power+vol does not work for me.. if it does.. i can't see because of the dead screen...
i have 2 options now..
(1) send it back in warranty.. this will take a lot of time and they will only fix not replace.. i guess
(2) open it and fix the display.

Hello,
Did you finally got some result?
I have exactly the same problem with a Samsung Galaxy Tab S 10.5. The screen suddenly went black although the light leds (home, back) were on.
I tried different combinations of buttons, usb charging and nothing. The only difference is that now the light leds are off.
---------- Post added at 08:46 PM ---------- Previous post was at 08:32 PM ----------
I have achieved to boot up the device because I have heard the start up sound and some notifications. However, the display doesn't work at all: the screen is black and there is no response when touching it. In addition, the light leds of the buttons are off now even when I push the home button.
Volume keys are working (I hear the sound then touching them).
Hard reset is VOLUME DOWN(left side on a 10.5) + POWER. Hold until it restarts.

But I can't figure how could this happen in a new (2 month) high-end product... I think that I will have to use the product warranty with the cost in time it involves.
This has happened to me twice during the last year. The last time was just ten minutes ago. I tried everything mentioned in this thread. VolUp+Home+Pwr for a looong time. Just PWR for a long time. I saw on my Wifi Router that the tablet was connected, but no screen. What helped me was to do a combination of everything mentioned here. What eventually got the screen on was 1. I turned of my router and 2. Home+VolDOWN+PWR for (what I believe was) 10-15 seconds. Then I got the choice to do a normal restart or a device reset. If you come this far, be sure to press VOL DN when asked. Otherwise your data will be lost. Obviously, I can't say if the router pwr off was necessary or not.
What's really weird is that my LG G3 went into a boot loop at about the same time (less than five minutes apart). They are not connected other than using the same router. I've had my LG G3 for exactly one year without ever experiencing a boot loop. The LG G3 is rooted, but my SM-T805 is not.

It's easy fix, most of the time due to loose LCD cable. If you can hear anything on the background but blank screen, 99% is loose cable.
Remove the back cover, disconnect and reconnect LCD cable, make sure it's fully inserted, then secure the connector with tapes. Test by plugin to charger, press the HOME button.
If you do correctly, the battery icon should show up on the screen. Then put back the cover, you're done.

Tablet won't turn on / charge

Hi,
I've only had my Samsung Galaxy Tab S for a few weeks. Whilst on a plane the battery went to 0%.. no problem I thought as I'd simply charge it when I got to a power source.
However, when plugged in, nothing happens. No LED light, nothing on the screen. I've plugged it into a wall socket and via USB into a PC. I have held down the power button, home and volume down for a period of time, as well as just the power button and volume down.
Has my tablet gone kaput?
Cheers,
Titanium
I'd just let it charge for a while. It'll take a bit before it comes back to life if it was completely drained.
If you still don't get any response hold POWER + VOL DOWN.

I had this problem.
You'll have to pry off the back cover, remove the wire that connects the battery to the motherboard. (A battery pull, basically).
Keep it off for 30 seconds. Then plug back in.
Use ifixit for details about opening. Feel free to ask for more help.
Try this one.
1) connect the tab to PC
2) press Home, Vol Down and Power simultaneously up to a screen appears;
3) press Vol Down to cancel and reboot the tablet.
John.
Now there are a few things you can try...
First check your charging port for any dust or any foreign particle. There has to be a small gap between the base of the charging port, and the small slab above it. Carefully, using a board pin, try and push that slab a bit up, don't apply too much pressure, just enough to make it move slightly!
This can happen sometimes if you drop your phone.
Next, make sure your charger, and the USB cable are working fine.
Also tell me if you have any Xposed module for your battery installed on your phone!

Thanks so much for that.
This morning, I plugged my tablet in to AC charge before leaving for the day -- battery was at ~30% and all was well. This evening, I came home and the tab was stuck at a weird Samsung logo -- not the normal boot with colored ovals, but the logo surrounded by a moving star field, never seen before, and could not get the tab to respond, turn off, do anything. Tried many wacky suggestions found on the intertubes to stop/start it, including holding power plus touching the screen for > 30 seconds, none of which worked. Never would have thought your suggestion for download mode would work, but it did on the very first try.
I'd like to know how the tab got into that state, and what that star field logo is about. But at least it's working again, for now.
Thank you.
That's the normal lollipop boot screen.
