Black screen but phone still fully functions? - Samsung Galaxy Note 20 Questions & Answers

I don't know what to do here, but his phone has never been dropped and it has never been wet. About a month ago this happened, started working again after about 4-6 hours. It randomly started working again. The screen has been black for about 36 hours now.
I am unsure if I can wipe the phone without being able to see anything on the screen. I am able to restart the phone and feel the vibration from the restart, but the screen will not show anything. He is able to make calls through the car still also.
Any thoughts? We can trade them in for over $800 right now, just need to get the screen functioning. Of course we don't have insurance.

My HD2 is dead ... Can someone give me some ideas?

I bought my HD2 about 3 weeks ago. Used from Australia (I live in NZ where the phone is not available yet). I got it from eBay, it's supposed to be 2 months old.
Phone worked fine, installed a cooked rom and everything was going great until a few nights ago.
I was playing badminton and had the phone in my pocket. When I took it out, it wasn't responding. So I pulled the battery out and when I tried to turn it back on, all I got was a white screen. I don't know if having the phone in my pocket while playing badminton had anything to do with it, but I didn't fall or anything.
Since then I've tried turning on hundreds of times. Most of the time it's a white screen with a slight yellow tint. Sometimes it's a normal white. Some other times it's a white screen with 'HTC', but in each case, it doesn't go beyond the white screen.
Have tried doing a hard reset, and it says it's successful, but when it reboots, same thing.
Have got it into the mode where you can flash the ROM (hold vol down when turning on), and when I tried to flash the cooked rom, it gets to 1% then resets. When I tried to flash an HTC rom, it just sits at 0% and eventually Windows gives me an error.
Have talked to HTC, and it seems I have to send my phone back to Australia to get fixed. But the service centers in Australia need a receipt/proof of purchase in order to fix it under warranty.
So it looks like I can't get it repaired without paying for it myself.
Does anyone have any ideas what's going on? Or can suggest something else I can try to bring it back to life?
Thanks

SGS2 not waking after locking screen

so heres the story:
when i lock the phone, the screen turns off as normal. but when i hit the power/home button to wake it and unlock it, nothing happens. literally, nothing happens. its as if the phone has turned itself off.
So whats happened is, I left the phone on the charger last night. it woke perfectly this morning when the alarm went off. no issues there.
I put the phone into my pocket and headed into work. i went to check my phone when i got on the bus and this was the first tme that I noticed that the phone wasnt waking. i eventually pulled the battery to get the phone to restart. i tried it again and the same thing happened.
later I made a phone call. the same thing happened again when i took the phone away from my head (the screen didnt restart, and I couldnt hit the End Call button cause there was none.)
since then, i've figured that to make sure the phone doesnt go to permanent sleep i have to do one of 2 things,
1) keep the phone music player running constantly, or
2) keep the phone connected to the usb charger.
clearly this isnt exactly practical for a mobile.
im not running any other Rom, its still the stock rom, android v 2.3.5, not rooted or anything else?
is this somethign anyone else has seen?
its called 'sleep of death' or SoD. some people has experienced this and some are able to fix it. it depends on what is causing it.
some blame it to the battery and the battery's contact point..
sometimes it fix itself after few reboots..
cheers for the info. Ill look into it and see if its worth trying to fix or just sending back.
no problem, i have this problem and cant do anything about it. i used load monitor to keep the phone awake, u/v a bit so it wont drain so much battery. but battery drainage still noticeable like 1% every 5 min..
just wondering, does it feels hot/warm near the camera lens when it happens? bcause mine does.
not particularly.
i finally got through to my provider and will be able to get it fixed/replaced soon. they just dont half drag their feet

Wet Phone confirmed working, but black screen.

Hello once again audience,
I have a big problem, and this is exactly what happened since 3 days ago...
At about 7 A.M. my brother was brushing his teeth and he sprayed water onto my phone by accident or something, so I thought it was just a little bit of water and just wiped in away. I did not TRY to use my phone until about 10 A.M. when I realized the screen was not working. I pulled out the battery and reinserted it to try to boot it, however I only saw the Samsung SII wordings for a split second before it blacked out.I let it run for awhile and then I realized that the touch key lights are working, and when I tap the center of the lockscreen I feel the vibration where you unlock your phone the little lock symbol. I retried this 5 times before giving up. Then about 5 hours later, I tried it again and this time it booted up nicely! Everything was tip top, except that 1 hour later it blacked out again... So when I reached home, I plugged in the charger when it is switched off and to my surprise I see the charging logo, and I tried to boot it up and it worked. It worked for 2 days. On Sunday, 2 days after the incident, first thing in the morning I wanted to check for whatsapp messages and I realised it blacked out again. This time I had ENOUGH! So I put it in some rice and checked on it every 4 hours. So now, I think it has improved. When it boot up I see the flickering of the Samsung SII wordings as before and then it boots into the ROM fine just black screen with working touch keys and everything else. But now when i turn the screen 'off' and turned it back 'on' using the power buttons I see catch a glimpse of the 4.2.2 lockscreen clock (very dark but clear) for about 1 second and it blacks out, just like when the Samsung SII logo pops up. This has been going on for about a day. What do you all suggest I do? Keep in rice? Keep it charging? Turn it off and try my luck hours later? I really need this back up as soon as possible, and thanks button would be pressed where it is due!
Thank you all for this too long message I really want it to work again!
In rice & don't touch it for a week, but given you've already used it immediately after it got wet, the damage may already be done.

Oke, lets say it's damaged, it's the screen that's damaged only right? hat would be chep to replace, yes?
The screen/digitiser are replaceable (whether you can do it or not depends on how confident/dextrous you are), Google search/eBay will give you an idea of how cheap. Or you could always ask a local mobile repair shop (then you'll obviously pay for labour, but if you're not confident enough to do it yourself...).
Edit - Mr eBay tells me I can get one for just under AUD$107
I would eat the rice, then sell the phone on ebay as "water damaged".
I have the same problem but its not water damage . The phone screen isn't turning on but the sounds and touch keys are working. What should I do? I have pictures on the phone and want to print them or save them but the screen won't turn on. Agh!

If the device powers on normally (except for the screen) and you don't have pattern unlock or other security enabled, it's a simple matter of powering the phone up and connecting to a PC via usb.....
The files should then be accessible via the windows explorer program.....

[q] need immediate help

After having the origional HTC Amaze i purchased sent back to TMobile due to my WiFi not working, they sent me a referbished one. 3-5 days ago my phone began to shut off at random times. But tonight it shut off, and when I went to turn it back on, it vibrated like it should but the screen stay black (No Tmobile splash or anything). I proceeded to remove the battery for 30 seconds (counting by mississippi's) and reinserted the battery. Again, it vibrated like it would turn on, yet the screen stayed black. I retried this process multiple times to no avail. I read on another thread that i should plug it in for 30-45 minutes incase the battery is dead. Upon plugging it in, the charge light booted orange like it should, but went out and the phone will vibrate like its booting, pause for 60 seconds and vibrate again.
I tried to factory reset it (Hold down the volume down key and press the power button) And it again stayed black and vibrated like it was trying to turn on, but the screen stayed black.
Im not worried about anything on the phone being lost or destroyed. I never tried to root it or anything, i just put music on it.
If anyone could help me, it would be greatly appreciated.

How long ago did you send it to tmo for the replacement? I would just send it in for another replacement if you are still within the time frame. If you never rooted it or modified it then it has to be a hardware problem or maybe try a different battery
Maybe 3 months ago? I don't have insurance but the funny thing is, it started happening when i downloaded a software update

If the device wont turn on, there is really no troubleshooting you can do besides trying a different battery. Call t-mobile and if they won't help you call htc directly, they have a 1 year limited warranty (i think it cant have any physical damage like its been dropped or anything)

LGv10 stuck on LG splash screen on boot

Hey there. Out of nowhere today my phone rebooted on it's own and is now stuck on the "LG Life's Good" splash screen. I have the AT&T version (H900) and bone stock everything (I have not messed with bootloaders or rooting or anything). I tried removing the battery and this also does nothing. Anyone else have this issue and know what to do to fix it?
Thanks
Update: After letting the phone sit for about 20 minutes it magically booted and is now working fine... not sure what happened.
Have you tried doing a factory reset of you phone?
1) Turn off the phone.
2) Then hold down the Volume Down and Power button together for a couple of seconds.
3) As soon as the LG logo is displayed, let go of the Power key, keep pressing the Volume Down and then press once more the Power button.
Afterwards you should see a factory reset menu on your screen.
4) Confirm process by choosing appropriate options using Volume rockers to navigate and Power button to confirm.
5) Now your phone should restart.
6) Success! The hard reset has just been completed.
I am having this same problem.
Was using Pandora and GPS. It cut off and has not come back on. I attempted to open in safe mode recovery mode l and tried to-do a factory reset.
When I did the reset It went through the erasing process but when it rebooted it stayed on the LG screen. I've tried all the "common" trouble shooting suggestions... Its been two hours now.
Any new experiences with this issue?
Im also having the same issue with my V10 - Verizon model. Watching a YouTube video and it reset and got stuck on the LG logo splash screen. Followed instructions to do a factory reset and after about 45 min of being stuck on the factory reset screen after I confirmed it reset and booted up. All data and setting were still saved, and after about 3-5 minutes it reset again and went right back to being stuck on the LG splash screen.
Any other advice? or is it just dead?
I am having the same issue with my stock AT&T V10. It randomly turned off, then I couldn't even get it to turn on. No charge screen. No Life's Good. I took out the battery and it would get to the blinking red question mark, but there is no way that I can see that I can use the phone without the battery. Sometimes the phone will boot to the LG screen, but mostly it will not. Even if it does, it will shut down after 3 mins or so.
Once I tried to hard reset it, and the phone just vibrated until i took the battery out. So I dont know whats going on. The phone has been running warm when playing Pokemon Go so maybe that's the culprit? Not like I was playing it all the time though.
Luckily I moved *most* of the new baby pictures over to the microSD. Ugh, I hope I can get the rest!

@downstat what a coincidence that i happen to have run into the exact same problems as you today. Phone turned off suddenly, wont turn off, took out and put back battery and now it goes into LG screen for a few, and it vibrates when i attempt safe mode. wth is this...

@jjall Very odd. Glad I am not the only one, though! I chatted with an AT&T service tech last night and he basically said he has no idea what is going on, but what he read about something similar indicated that the phone and all the files are most likely corrupted. Luckily I moved most of the photos over to the extra microsd, I am going to an AT&T service center to see if they can work any magic and retrieve any other files. Last night the tech started a warranty replacement and the new(ish) phone is on its way.
I did get it to boot to the white safe mode screen but was not ready to say erase all, just in case it erases the photos. I chose to restart the phone and nothing, just black. Every once in a while the phone will just vibrate for 30 seconds before shutting down while the screen is black. Other times I get the soft vibrate as though it is turning on, but nothing happens. Some times I get the LG screen, but then that just turns off. No rhyme or reason except that I at least get some response after the phone and battery have been apart for a while.
I'll update when I get back.

Yeah. I get the same thing. I'm taking it to att today to see if anything can be done. My only problem is that I dropped the phone a few months ago, the only time i've dropped it, and lens came off without me noticing. I'm pretty sure that voids the warranty. Either way, i'll see if i can pay for an upgrade or something. Good luck to you.

My guys said they could not do anything, but as I was playing with the phone, it magically came to life! I was in the process of moving all the photos to the microsd, then it froze, crashed, then wouldn't turn on. So it's possible! They mentioned taking it to a cell-phone tech place to see if they could do anything as they have better tools to help fix things. Dunno what that would do to the warranty. The tech guys did say they dont carry any spare parts or batteries for the V10 because it never has a problem. I told them that there is a rash going around and they might see it soon.
I did notice that the colder i kept the phone, the more of a chance that it would *at least* turn on, before crashing. So at least there is hope...somewhere. Hoping a new battery will help maybe, even though it seems to be a hardware issue.
How's your luck @jjall?

Actually, i just got home and I decided to try out to see if it worked. I got the 0% battery sign. Plugged it in and it actually seems to be charging! So i'm hopeful. I also noticed that my phone has been getting hot lately. And that my battery life was crap. But that's just LG. I talked to an ATT customer service rep. and they told me that I could have the camera lens replaced so that my phone would be covered for an exchange. Even if it turns on, i'm going to exchange it just as soon as save all my files. Hopefully they'll take it now that it's working....
EDIT
it decided to turn on while it was charging. Froze on booting screen. It was HOT. Like I almost dropped it.
Hmm, I was going to say "CONGRATS!" but sorry. Did the battery get hot or did the phone itself get hot? Feels like mine is getting hot at or near where the led flash is. Gonna let it stay in this LG welcome screen for a bit and find out. I'm wondering if a new battery would help, but I have to wait until the 19th though before my replacement shows up.
Also, were you playing Pokemon go before? Wondering if that is what started this all.
Hello!
So the same thing happened to me. I was not playing any games on my phone. I had JUST clocked out of work using an application on my phone and sent a text. It has turned off on its own and didn't want to even turn back on. I removed the battery and set it back in.. it turned on to the LG screen and stayed until it blacked out again shortly after.
Same issue with TMO LG V-10 here. Was using phone and it went black and shut down. Now in a loop with the LG boot screen. It tried a few times then just goes black.
Well I just got my replacement and the new battery didn't do anything to help the broken phone. Guess I am going to lose some important pictures. I have a few days to keep on trying before I have to send it back to AT&T. Interesting this is happening to a few people all around the same time.
@Buzzbee21 did you notice your phone running hot at all before the shut down? Mine was running hot a lot, so maybe the heat protection is the problem.
At time yes. Not so much when it did quit. However, I left it sit on a fan and chilled it, and one time when I was able to get to the wipe screen, before it quit again, it got very hot in the afformentioned area.
Less than a year old. Getting a warranty replacement, but still disappointed as I think having the replaceable battery and abiltiy to put a large Micro SD card in it, along with the finish, camera, and Audio make the V10 one of the nicest phones out there.

this may sound weird but the same thing happen to me.... put the phone in the freezer for a while then boot it up but be prepared to get your pics, music, etc off of it quick... mine works fine until it warms up to room temp, then back in the freezer it goes to do it again... did it like 4 times today and saved over 1600 pics, bunch of videos and music. (saved them to a mircoSD card)
Wow. This happened to me last night, and I thought it was the weirdest thing. I wasn't even using my phone. It was sitting on my dinner table, and I noticed the screen on with the LG logo. I went over and picked it up. It stayed on the logo a few minutes, so I took the battery out. Then I turned it on, nothing but LG screen. I kept messing with it with a combination of Power/volume down and finally got it to come on to my home screen. It worked for about five minutes before being wonky again. I took the batter out all night. I'm hoping that I can get it to come on again today (I've tried 10 times and not been able to) so that I can make sure the developer options is checked, then I can hook it to the computer and mess around with it.
Thanks for this thread. It seems most of us just started having this issue in August. I'm planning on getting the V20 next month, but I need this one to last until then. haha Please keep us updated if anyone figures anything out and I will do the same.

SO, not saying this will help anything but, after messing around with the phone for several hours I've learned this:
If you take the battery out, then plug it into your laptop, then turn it on: a battery icon will pop up with a ? on it.
From there, if you hold down the VOLUME down key, and insert the battery, it will take you into the quick boot menu automatically. Unfortunately I never set that up, and not it will not allow me to set it up. I assumed I could get to safe mode from there. This is the first time I've seen where I would have to "set up" the quick boot menu. This is my first LG phone though. I usually use HTC, or MOTO.
Now, the more interesting thing is, begin as I did last time.
Phone off, battery out, plug into computer, power on. Then hold the UP volume key as you insert the battery and it will take you to your "Tethering" option. So for most of you that have this problem, maybe you will be able to get the data to back it up. Unfortunately for me, it tells me I have to do a Firmware update first, and to not unplug the USB connection until it is complete. If your firmware is up to date, maybe it will allow you to do back up (I thought my firmware was up to date, but guess not).
I hope this helps someone, and I do hope that someone can build on what I've done so far so we can figure out how to at least get our data off the phone.

The phone got hot. It was getting hot starting from around the power buttons. And it sometimes got hot before i downloaded pokemon go. Not as often, but it happened from time to time. I think it might be because i'm no longer using the original power usb cable.... idk. Just waiting for a replacement.
Can you say the first 3 digits of the serial number of the device to boot loop problem?
