Phone works but screen wont turn on. Please help - Samsung Galaxy Note 20 Ultra Questions & Answers

So I was using my phone not doing anything special and the screen wont turn back on. I was somehow able to get into the boot screen and it rebooted and worked but now nothing works. I've tried holding the power button and volume up but the phone just never restarts. I've held the power button forever and it never restarts. I went to at&t because its still under warranty but they told me they dont do that and i have to call a number.
My issue is I have some files I need to get off my phone and it does still work. My alarm is going off now but does anyone know another way I can try and rest this or access my files? I've even considered going to a phone fix shop. Not sure if this is a software issue or a screen issue but its nothing related to damage or water etc.
Any advise appreciated

reboot is power+vol.Down not Vol.Up.
if you ever get the phone back on, report the issue to Samsung Members app on your device (may need to install the app).
Otherwise you can talk to Samsung using their chat feature on their website.
If your phone alarm is going off and etc. etc. then it's very likely just a screen defect. If it's deemed as Not a user abuse then Samsung probably will replace the screen for you.

G1 won't boot

Hi all... and sorry for my bad English ;-)
I've got an HTC G1. When I try to start it, nothing happens. Only the backlight turns on ... What can I do?
do you have a rooted g1 with recovery and engineering SPL?
No, it isn't rooted...
Is it brand new? I think you should be able to exchange it, if you got it from a store that is; unless you got it from online then you will have to contact the website and see where that goes.
No, it isn't brand new. Someone gave it to me... So i can't exchange it.
Try to boot it thru camera+power holding. Wont help you if success but at least will tell you where the problem.
if he can go to recover mode screen wont remain completely black as far as i know. Because splashscreen appear before recover (or other) mode starts. I might be wrong of course.
If I try to go into the recovery mode thru camera + power button, nothing happens. Only the backlight turns on (black screen with backlight & keyboard backlight...)
Follow first 6 steps in this form...

tihs should boot your G1.... then if you want go on ahead with other rooting steps to root your g1..
I tried the first 6 steps, but it won't work. I think I can't entry bootloader mode. On step #4 (...)You should see a gray/white screen with instructions(...)
nothing happens on my Phone. :S
Isn't it possible, to flash the bootloader/firmware over USB or something like that?
*push* no solution?
are you sure the phone does not boot? Does it rumble when you first turn it on?
I have a similar problemb, but my phone will completely boot and work, but the lcd does not work it stays black. i can move apps around (they rumble when you pick one up), and i can recieve calls.
I was able to get it to occasionally boot with the lcd working by rebooting the phone with call+menu+power. It worked long enough to reflash the rom to rc29, and boot into it. Then it died shortly after.
mine is going to htc.
Yes, it does rumble when I turn it on, but I think it doesn't boot. So I can't "move apps around" or "recieve calls"
And I can't use the warranty, because I'm swiss.
another way to tell if it actually boots is plug it into a pc after giviing it enough time to boot, and listen for the usb connection notification sound your phone should make.
just trying to help you narrow it down. When i am contacted by HTC i will be sure to try and get as much info from then as possible. hopefully ill get something that might help you.
Since you wont have to worry about voiding your warranty, I also suggest snagging the factory service manual and make sure all the flex cables/connectors pertaining to the lcd are properly connected. This, of course, is under the idea that you have the same problem as me.
good luck
When I plug the phone over usb into a PC, the pc find it as "HTC Android Phone USB Device".
Hmm I don't think, that the LCD is broken, because the backlight turns on... If the lcd is broken, the backlight won't turn on, right?
the backlight on mine would also stay on. then again my lcd worked intermittenly at first and proceded to work less and less, but the backlight would remain on. However, I think your problem differs from what I encountered.
The fact that your pc recognizes the phone means the usb controller is working, but thats about it... I am just trying to find out for sure if you phone boots or not. That will help narrow down the problem for sure.
Have you tried calling it from another number?
It also never hurts to take a peek at the factory service manual... if you havent already
thank you. hmm... I think I can't recieve phonecalls.. but I'm not sure. (I tried it, but yeah i don't know. xD it doesn't rumble or something like that...) Is it possible to have "remote" on the phone? So I can use it over the PC?
They have shipped my phone back. Apparently the screen dying was a side effect of the keyboard going bad...The keypad did not give me any problems though. I was told they replaced the keypad FPC (part no: 73H20137-41M, pg#102 in the service manual). They replaced nothing else.
Unforutnately they did not have any more info to give me. In your case, i would suggest opening it up and checking all the flex cable connections to ensure they are properly and fully attached. of course this check is not really for the faint of heart technically speaking, but it shouldnt be too bad with the service manual as a disassembly/assembly guide.
are there any tutorials how to open the g1? =)

G2x continuously rebooting the lg logo screen

My phone runs perfectly fine until I enable Gps location. Once I enable GPS location, it freezes, then it reboots my phone and it slowly do a system check, then it continuously rebooting the lg logo screen. I tried taking out the battery and put it back in, even took out my battery for a day and it still does the same. I'm not sure if it's the hardware problem, but it's a pretty rare case, since I read most of the threads in forums, people said it can be fix once you pull out the battery, but somehow it's not working for me. Anyone knows the reason why? Btw, my phone is not rooted or used any 3rd party program.
Ah. Posted too soon. There's a master reset that I believe is Power and Volume Up. Try that.
Unfortunately, it's still not working. Is there any other possible way? Or else I have to call in and return it.
Try turning off the phone, then press power + vol down and hold it until you see the word android. This should do the factory reset.

It sounds like the permissions are not correct, or perhaps that your ROM was not flashed correctly. I have seem this problem happen numerous times due to bad firmware flashes or ROM issues. I would just download a new copy of the latest CM 7 ROM or whatever your favorite ROM is and flash it through CWM.
Thanks guys for the help. I found out that you have to hold down first then power button for around 30 second and then the droid animation comes out. I was so close to returning it. Thanks!

SS RDX mode

Question from pure novice,
I was factory resetting my inherited Galaxy S20 phone, and got an unwanted screen not the screen expected , I can not get into the factory reset screen, can anyone assist
i let the battery deplete and attempted the factory reset and was successful but.... it still wants my sisters password or google account password , I might as well go ahead and root the phone
Did you fix it? I can point you towards an easy to use service thats cheap and I'm not promoting anything it's just what I use if I don't want to spend a day getting in to a phone. it's a guy I've used a few times from ebay and he's prompt and gets it done quick. Otherwise the ways I know how to do it might not work on that phone since it's newer but I know of a program that might open the browser and then from the browser you download a launcher app to get in the phone but will have limited access to a lot but can then download an app that might fix it.
I have a Samsung Galaxy S10 Plus that keeps shutting off and going to straight to SS RDX reboot screen. When I hold down the volume down and power buttons at the same time for 3 seconds it restarts back up fine but this happens frequently where it will shut off at a random time and restart back up again. Does anyone know how to completely stop this from happening to my phone please? I just finally unlocked this phone and switched carriers and now I can't even use my phone without having to worry when it will shut off on me again.

How to force shutdown without touchscreen.

So my Note 10+ screen broke so that I can only see the top 15% and only touch the bottom 60%. I booted into TWRP to backup everything, and now I'm in a situation where I can't turn the thing off. I am unable to press the shutdown button, only the download mode and recovery mode buttons. I am also unable to press the ADB side load button to send a shutdown command. It will be quite some time before I am able to fix the screen, so I don't want the phone battery to be sitting dead and degrading for a month or more. I already tried draining the battery and then plugging it in to charge, but the phone automatically booted into TWRP.... hardware key combos only reboot, they won't shut down...
Does anybody have an idea how to power off my device? Or to reboot into system or gain ADB access without being able to use the touchscreen? Thanks for the help
Humm, after reading the "how do we make XDA a better place thread", and the "this place is just not as good as it use to be" thread, I thought I would try to help. But I suppose that if you were on the forum since 2010 you have probably already thought of this. Also, I don't have a "Note 10+", so this is just guessing based on general Android behavior.
My screen is also unresponsive and I was able to reboot/power off by just by holding down the power button for half-a-minute. Sometimes I would have to "pull the battery", as soon as the phone started to reboot. I've done it a few times and haven't bricked the phone yet. So it is not something you do not want to do all the time. But then again this response will probably not be helpful because your phone does not have a removable battery. (whether or not a battery is pull-able is not something generally listed in the phone specks unless you do lots of digging).

Yeah unfortunately battery is sealed inside and holding the power button yields no result
@TheLexx
Take phone to authorized service center and let them fix it.

Question Z flip 3 bootloop

The problem I have is with the galaxy z flip 3, it worked just fine inthe morning but after it ran outta juice and I charged it to a certain percentage, it stopped working properly, and got into an infinite boot loop, I tried forcing it to restart by long pressing volume down+power , but it didn't work, then I tried opening the recovery by long pressing on volume up+power and yet it also didn't work (I think that maybe it's because it was trying to boot at the time), so have you guys any solutions , please do help me cuz this phone really is important and with all honestly, isn't even mine XD, I'll be waiting for an answer
Your failsafe options are contact Samsung or do a factory reset (and then potentially contact Samsung).
If you can't boot it to anything, the only real option you have is to flash firmware, which likely won't help without wiping.
Unfortunately, not booting doesn't have a whole lot of options that don't wipe data without being rooted. Even then, you'd need recovery.
I see, then I may consider giving it to samsung, as long as they won't reset it, cuz the only reason why the phone is so important is because of the data, altough, isn't there any other way to acess recovery? Cuz I had this problem with the s10 before and I fixed it somehow (a certain Bixby key combination), but this time it seems there isn't any hidden combination.
Samsung is going to reset it. It's a required first step for them to do any work on it, even if the work has nothing to do with the software. What may help find a way to recover the data is starting with how it got to this point. Did you install anything new, change any important settings, or anything else that could have been a part of the issue? If not and it is an unexplained hardware failure, the data is likely gone already.
If it's something you might have installed or changed, it's possible that putting the phone in safe mode and undoing it may solve the issue and let you boot normally.
Booting into Safe Mode:
Make sure the device is powered off (charging is ok, as long as it is not currently trying to boot)
Hold the side key to power on and continue holding until "SAMSUNG" appears and the device vibrates
Immediately release the side key and begin holding volume down until boot completes
If the device has booted into safe mode, you will see a translucent "Safe Mode" in the bottom left

Well I just asked the original owner (my mother), and apparently she doesn't remember downloading anything new into it, and it just went crazy by itself, also something else I wanna note, I tried charging it and it booted into recovery all by itself, I taught it was weird but Still went and wiped the cache and then when I tried restarting it it suddenly ran out of juice once again, also, it's second display shows some weird curruption/bug or glitch-like lines. So based off of this, can you really find the origin of this problem and if there is really any hope of saving it's data XD. Thank you btw, and once again, I'll be waiting for an answer
There are hundreds of reasons it could do that, including a faulty board. Thanks to the removal of physical sdcard support, you'd need to get it to boot into something with at least adb support to pull anything off it. Stock recovery doesn't provide any ways to perform a decent backup, but it sounds like the only option that wouldn't wipe the device didn't work.
I see, alright, thanks a lot, I'll consider resetting it
It may be worth trying to flash firmware first. Go into it knowing it may reset the device or leave you needing to reset it, but it doesn't hurt to try if you run out of safer options.
Same here, same symptoms, happened in front of my wife's and eyes face. We are fairly techy and understand our way around our devices. We also noticed the device crashed then would make it all the way to the home screen launcher and before catching signal the crash would cause a restart at that point I went in and did a cash swipe rebooted right back into recovery by itself then I unplugged the cable and it was acting as if it has a dead battery but when the cable was last plugged in during a couple of crash and then restarts all the way to the home screen I know the battery was at 70 something percent. My next step is going to probably be flashed the current firmware that just released on top of it as a dirty flash and see if I can get it to boot. If not then I'm going to do a hard reset and see if that works. When plugged in it automatically starts exhibiting symptoms as if the buttons are stuck. The devices in the OtterBox and it's fairly brand new I would say mint. Not dirty or any smudges either. all I'm saying is I'm one of those type of technicians that say yeah right when people say it just happened I don't know where but this actually happened I don't know when I was able to witness it. I'll come back and let you guys know what works and what doesn't. (By the way excuse my grammar I was voice typing while driving )

Hello everyone just a quick update. Once I got home I plugged the device into a Samsung fast charger and Samsung OEM USB type-c cable and realize the device booted all the way to the home screen but register the same battery level as I mentioned above. Device was working as if nothing happened to it. So I updated all the apps on the Galaxy store then updated all the apps left over from the Google Play store, I then proceeded to check for a firmware update because I know the April update just released and installed the update with no issues. Updated the apps that needed to be updated again somehow there's always something and unplug the device from the power cable. Everything was working if no issues about half hour later the device cuts off and does not want to power on. FYI I already had my wife contact T-Mobile and get a warranty replacement we only paid $5.00 so my thoughts and conclusion on what's going on something happened to the battery or it's defective. Btw we only use Samsung OEM cables and equipment at home and in the car while connected through Android auto. it's only working while being plugged in it's not charging all the way even though it's registering it's charge level while the device is on.
