Screen going black

I've tried various different ROM images (including the excellent Dr.Gonzo), and I have this problem with all of them.
When I'm using the phone either with the keyboard in or out, the screen just switches off randomly. If I wait a few seconds (possibly the backlight timer length), then it comes back. Mostly... Othertimes I have to wait a lot longer, but it does always come back.
A reboot sometimes fixes it, but not always - does anything survive a reboot or battery removal?
Anybody else seen anything like this? I have seen a lot of threads about the screen staying on, but not off.
Of course, it could be a hardware fault, but because it's intermittent, it's hard to prove.

same problem

If you shake the phone can you re-produce this problem? I've never not heard of this being affected by software - you might also want to ensure you're not overclocking it.
Nothing is removed when you do a battery removal or reboot, ensure your connections are all tight and make sure the SIM pins are all making contact and the SIM door closes, apart from that it sounds like a possible bad LCD ribbon.

Shaking it doesn't reproduce the problem.
Once the phone has started doing this, it happens everytime you press a key.
Seems more like a memory leak to me since it always seems to happen after a while of web browsing/email use.

So actually, it looks like it might be a hardware fault.
I think it happens when the device gets warm. After a few minutes with the screen on, keyboard lit up, wifi on, the phone gets pretty warm and that's when the screen seems to go black. Leave to cool and all returns to normal.

Same issue here, but the screen does not acually go black/blank it just seems that the screen backlight does not turn back on from a standby like state, the phone itself functions but just not able to see whats going on on the screen.
(keyboard lights work fine and come on when expected)
Not sure about the heat theory as it happens (to me) most often right after a call, anything over 30-50 seconds and the backlight problem occurs, when it decides to work again is a matter of luck.
As said before because it's intermittent, it's very hard to prove.
Has anyone who has had this issue, fixed it with a hard reset ?
Very strange ... but also getting very annoying now!

i got the same thing. took it back to warranty and they said nothing's wrong with the phone but i still get this.

I experience the same problems.. it happens pretty random, but every time when you hit a key. I have set all timers to never but the problem is still there.
Running Gonzo 1.1 at the moment, upgraded from guava.. but that didn't solve the problem.
It is getting so annoying now that I am about to throw the s710 in the dustbin

I have had the same problem!
I have turn it back to my provider and no problem now.

i have the same problem with my VOX
apparently, i can still receive phone calls, and do whatever i want with the phone,
but the screen just stays black, its like if you have unplugged your monitor
since i dont have a htc center in my town or anywhere else nearby.
does anyone know a way on how to open the phone, change what need to be changed and correct the problem? im all up for testing if that would resolve this annoying problem :s
cheers everyone

there is a dismantling manual somewhere in this forum. search.
i don't think taking it apart would help you because this is not a physical fault that you can locate.
and i learned that mcel is the retail seller of vox in mozambique. they should be able to help you with service. else just send a mail to htc support and they will guide you.

yes, mcel are the retail sellers, but i tried to go there, and there are no specialists on htc's there,
the thing is, i didnt bought my htc from them, so i can't go there and change for another one
but tks anyway

no problem
but do try to contact htc support by email. they might suggest a way.

I'm having exactly the same weird problem and I think I found some pattern when it occurs. Well, the thing is that in the bright day or in a room with lots of light it works just fine. In the darker conditions… well… not so fine. It seems to me that this screen blackout happens whenever the keyboard light is on and screen changes to full brightness (in the dark, because of the light sensor). In the daylight, keyboard light doesn't turn itself on, so s710 works. I don't know much but this definitely isn't some bad contact problem. Maybe some battery problem, but I doubt it since I can receive phone call in this condition. This started to happen after I flashed this Windows Mobile 6.1 ROM from HTC (I have original S710). Flashing Dr.Gonzo's later on didn't bring any luck either. I believe that some power control SW is the main culprit. I've read that many people mention some Tornado Power Control app. Does anybody know can this application be permanently disabled or removed?

are you trying to say that by desabling the light sensor, the problem might go away?
i would also like to know if it possible to have the baklight on the lowest possible brightness forever, because it seems, on a low brightness the problem might go away

I also have this problem with the lightsensor turned off. And also at (as it seems) random moments.

well, even with the light sensor turned off, the problem persisted.
i got my phone to a repair shop of htc's, and they figured out the problem
my phone is now 100% thankfully, the repair man told that the problem was because of bad or malfunctioned circuits, he exchanged them with new ones, and the problem went away,
dont know wich circuits exactly, and he didnt want to tell me, but i suggest anyone having the same problem to try and do the same
probably its a hardware malfunction with these VOX,
its possible since so many times before i've heard about malfunctioned pieces coming out in large quantities for sale.
anyways, cheers everyone, and good luck Portugal in EURO!

I have the same problem. I just noticed that it usually happens when the phone is warm, so if you need to do something on my phone just... take some ice from fridge and put it on back of your mobile. I cant see any more solutions.
Please someone help us!

Update. Problem Solved
Just thought I'd update this thread I started.
I sent the phone back to my dealer (Grapevine in Poole,UK).
A week later, I got a brand new one back from the HTC repair centre.
So far, so good. Looks like the problem's solved.
Mike

Sam problem here,
i called with HTC and they sent them to there repair centre.

About the screen (bottom part)

Okay so I've had the HTC Fuze for 3-4 days now and 1 thing that i noticed is in the screen, by the bottom (where the touchflo is) the screen is like "blinking".
It's hard to explain, but if you get closer to the screen you see like its moving and shaking but when you look at any other spot its not.
Is this normal or my device could have a problem?
Oh and sometimes when i use the keyboard and the screen rotates, the "right side" which is the bottom (keeps blinking) sometimes has the letters of the menu before i rotated the phone, so it has like letters with opacity there as if OVER the screen.
Any of you have this problem? Or is it just me?
What can I do? My device is still in warranty but its a really small problem, it just bothers me the screen like that.
Thank you.
PS. Ill post a video if you want to see more clearly.

not normal

I agree this is not normal. Reflash your ROM.

I've never done this before. But i wanted to take all the A&T stuff of my phone and make it faster. What ROM would you recommend me?

There's other threads about this on these boards. It's a hardware issue with the Fuze, and yes, it is normal. I've gone through 4 Fuze's, all of them were sent back on warranty, because of this exact problem. I just seen a thread not too long ago about it and someone mentioned that it was a hardware problem but I really don't remember his/her explanation of it.

Oh so should I send mines back or just keep it?
It doesn't bother me at all, i mean, i could live with it, but sometimes i think it would be better if it didnt do that.
It just happens when my device is hot. I mean, when you use WIFI the phone gets warmer and thats when the screen starts doing that, when i turn it off and let it rest it works fine again, and sometimes when i put it in standby mode and then back to normal it comes with the blinking thing and sometimes not.

Like I said, I've gone through 4 and still have the problem. My advice, either switch the TF3D look so it's not as noticable in portrait or just switch a totally new ROM with a new TF3D look. It's still going to happen but you'll notice it less. Even on this new Fuze it's still happening. I'm using EnergyROM Mercury right now, and while I still have the problem, it's nowhere near as obvious as before.
Another thing I've noticed that seems to help a bit from time to time is to turn off the screen and plug the charger in. Weird, but it fixes it sometimes. As you also noticed, it only happens when the device is hot. A prime time for it to happen is when you hang up a call.

[Q] screen disaster - random tinting, solarization, turns upside down

sooo, yeah. my wife has the t959v. the screen cracked months ago, replaced it with one from ebay, works fine. a few weeks ago, it was involved in an accident and needed yet another screen replacement; ergo, back to ebay i go. installed the new screen yesterday, turn it on, all is well. for a bit.
now, the phone isn't currently, nor has it ever been rooted; pure stock tmo us 2.3.6. during boot, the splash screens and boot animation are gorgeous and perfect in appearance. the recovery menu is exactly as expected. android boots as you'd want it to, and then the display will do one of the following:
-work properly (rare)
-automatically turn off, capacitive buttons still lit, touchscreen unresponsive - turning it "off" darkens the cap buttons, turning it back on flashes the screen on for a half-second, then off, with cap buttons still lit (common)
-graphical corruption ("solarized" colors, completely wrong colors, pixel vomit in essence) (fairly common)
-screen tinting, blue most often, followed by pale yellow, then greenish, then red (almost constant)
-screen inversion - the display will show as rotated 180 degrees; grabbing a framecap in ddms shows it right way up. touches are also inverse; you have to touch where the onscreen element would be if it were displayed properly instead of where the element is; e.g. a button on lower-left will display in the upper right, upsidedown, but the screen registers the button when you touch the lower-left portion of the screen. (quasi common, equally infuriating and hilarious)
none of these problems will show up in a screenshot at all.
i can reliably reproduce any of the above by simply adjusting the screen brightness. this will, quite literally, cycle through every possible defective display mode randomly for a split-second before moving on to a different one as long as you move the brightness slider.
MOST of these issues are transient and are either fixed (temporarily) or replaced with a different listed issue if you lock/unlock the display. it feels like a hardware issue what with the solarizing and color horrors, but is acting like a software issue, considering that recovery and boot are perfect and have never displayed any of these issues. i tried gently flexing and stressing the case in areas that might be a weak connection point, but can't get it to bug out that way.
in no way am i suggesting that i didn't screw something royally in the reconstruction stage, but i tore down and rebuilt that phone 4 times with identical results, so i can guarantee it's not some loose ribbon connector or zif socket.
i beg of you, great minds of xda, what the balls did i muck up this time? any hope for a fix? are there different panels, drivers, something?
thanks in advance

OK, if your screenshots appear normal, then your phone appears to be working correctly!
or at least it thinks it is we can conclude that it isn't the rom, kernel, or anything that you can blame the phone for going screwy.
Try buying another screen??
The ribbon connector might be broken?

yeah, these were what i figured what my options were. it just seems odd that the boot process and recovery menus have error-free displays while only the full android os doesnt. oh well, i'll probably just have to make a stink about it on ebay or something.
thanks for reading

You might try a fresh flash before getting a new screen to see if it is indeed a hardware issue. If you want to try that follow the second link in my signature. You will not need to flash bootloaders since you are currently on KJ6.

hell, warranty's void at this point anyway, right? may as well thanks much!

welp, all went well, screen was perfect through the whole heimdall/recovery process, but the problems still exist in the os c'est la vie. at least my wife's phone is finally rooted, i suppose. thanks anyway!

Have you tried opening it back up and reconnecting?

yup, 4 times, but i guess one more wont hurt
[edit]
it definitely seems to be related (if not related, exacerbated by) changes to screen brightness. turning off autobrightness has helped minimize the issue, but it still presents itself semi-often during screen-off/on events. obviously nothing useful in logcat.

That's interesting and could very well be a hardware problem with the screen. You wouldn't see that in recovery as the OS isn't loaded to mess with the brightness in that mode.
Does it do it on-demand if you mess with the brightness slider?

you better believe it does. rapid fire cycles through every color until it can't take it anymore and turns off. if i take/refresh a screenshot through ddms and poke blindly at the screen at that point, it'll still take input which is a curious, difficult game to say the least.

It's that Pink Floyd screen. You're supposed to drop acid & watch the wall when that's going on. LOL j/j
Given that you're on a fresh ROM & the problem persists, I'm leaning toward a hardware issue man. Sorry.

as fun as that sounds, unfortunately i bet i'll end up just getting my wife a used phone on ebay or somewhere similar and using this one as a development monkey. i was assuming that it wasn't something i could fix but hoping otherwise... yeah, that worked out

I just started having this problem. It wasn't too bad at first, just the color changes, but then it started not showing a screen at all. Changed to three different roms, even back to the stock non-rooted KJ6 and gave up. Keeping it on a steady brightness is the only way to minimize the color changing. I thought your thread had a solution but...
I may try opening it up and fixing the ribbon. But otherwise I'll keep using it as long as I can tolerate it until an S3 or a new Nexus.

nawp, nothing even close to a solution here i did end up buying my wife a whole new replacement phone and turned the broken one into my api10 development device. for what it's worth, yeah, autobrightness off does help a bit for when the phone is actively displaying content, but after you put it to sleep/screen off and try to turn it back on, it's a crapshoot. for a few horrifying hours, the screen was upsidedown even in recovery/boot animation and would NOT flip back to right-side-up until i ran the battery completely flat.
is no fun, 'tis truth. sorry for your troubles.

Flicker screen

Anyone have their screen blink/flick on startup, on when you see sense rings for unlock. This doesnt happened all the time but you will notice it once awhile.
Is this hardware issue or software? Its not custome Rom I'm running. I tested out other and it sometime occur. On HTC One X it mention about this also.
Any input would be helpful. I don't like to flash Rom all over too see what caused it.

I had an issue with Apex launcher. Every time I would select a folder on the home screen, the screen would pixilate, tile and flicker, not in that particular order. I uninstalled Apex and now everything is fine.
I read that the type of screen used on the One S has a type of matrix pixel or something that can be seen by a trained eye. Could that be what you are seeing.
hTc One S

I've been testing with this flickering. It noticeable if I restart my phone and look at the screen before the "sense ring" pop up. The screen will flick once. This occur on stock, custome Rom so I might think the hardware is acting up. This issued is known on HTC One X.
I restore back to stock Rom and move between app it also flick. Messed with brightness seen to help, but once I select auto brightness it come right back.
Man I'm not happy

Talked to Htc rep. they might consider the display went bad. Usually, the screen shouldn't blink. Even when I reopen an app..it still flicker and turn black screen.
Next steps called back Tmobile and demand a exchange because I'm not happy with my $600 phones..that blink like strobe lights
Maybe I should never buy the first patch that released on launch day. LOL

Sooo... mine started doing something weird this morning...
Is it anything like yours is doing?

Well it was weird, it was fine last night, even had done a backup on clockwork. took it off the charger this morning and restarted it. looked at it later and half the screen was like that. I restarted the phone again and it only did what you saw, tried restart couple times still came back but later on as I was finally leaving home I was texting someone and it just went away?? tried restarting it again nothing... not coming back?? no idea why. I did see on youtube another person with a one X doing the full screen like that, SCary.
I would return it but I'm rooted 2 months in and had to buy from someone else's upgrade so I'm not even sure what they'll tell me if I take it to the store or talk to HTC

I got replacement from T-Mobile since there 90 days exchange warranty and guess what? My screen still does it. I went ahead called HTC for advice and rep. Told me it just parts of O.S.
For yours side, if you sent to HTC for a repair. They might check if you tamper with phone and will charge extra :what:..
Hopefully it won't do it.
Sent from my HTC VLE_U using Tapatalk 2

only once in a while, when on lowest brightness, the screen would flash up very bright, after pressing the on button but than goes back to set low brightness.
Don't have an Issue like in your video

I've reverted the phone back to stock, not only does it still do it, but it was doing it while on the restoring mode. I've called T-Mobile, they are sending me a new phone. Unfortunately now I will be getting a refurbished phone. Pretty unnoying.... Hope its not defective too in some ways.

I have the same issue, but in a bigger area. I noticed that it happens when the screen is too cold.
First time it happened was when I was taking some pictures outdoors and it was under 0°C and snowing.
Second time also outdoors, strong cold wind, but above 0°C.
Don't know if this is really the cause, but it always happens under these conditions.

Mine originally started on a random morning, I live in Cali and phone usually on my bed so granted it's not under the blanket I'd imagine it stays fairly warm at nights. tho I had touched the screen with wet hands before and I've always been curious if that would have done it. I did since get a replacement which I haven't babied as much as the original one, it's been few months and seems to handle itself fine now (crossing fingers).
But if it happened once, it will happen again, mine came and went couple times, here is couple vids of the way it got... but eventually instead making a transparent gray, it was a full shade of it blocking that half of screen that wouldn't go away.

Question Screen Flicker During Unlock

Every time I unlock my screen, whether it's with the fingerprint or pattern, the screen will flicker for half a second. Super annoying because it's a bright white flash.
It's not face unlock assistive lighting, as I've ensured that is turned off.
I've also tried every display setting possible, toggling things like vision comfort, comfort tone, refresh rates, display calibrations, changing wallpaper, and so on.
Really hoping this isn't a hardware issue because I'm also noticing my touches don't register all the time, unless I'm pressing the screen slightly harder. Not sure if it's my screen protector but I am left a bit concerned.
Any ideas? I've Googled this a bit and I've noticed others have the same issue but on OnePlus 6 devices for the most part, not the 9 series. If anyone has run into this before and knows a fix, I'd love to hear it, thanks!

That's how the fingerprint works. It increases the screen brightness to the max usually. It's the flaw of using that kind of fingerprint rather than sonic like Samsung. Believe it takes a picture of your fingerprint and compares vs ultrasonic gets a 3D image, the difference is in speed too, optical is faster, but ultrasonic technically more secure and does not rely on lightning conditions. I personally prefer the hardware on the back kind over both.

I don't remember it being this prominent on my previous OnePlus devices, though. My 8 Pro did not flicker as aggressively as this one does. It's enough for me to clearly notice it, even in brighter areas; this is why I've been left with a bit more concern than usual.
Not to mention this occurs even if I use my pattern to unlock.

Not sure. Mine does the same but doesn't bother me in the least bit. If it happened at other times other than unlock would be different story.

Any chance you could try and make a video of it happening on your device? I just want to see if it's the same thing as mine. That way, I'll have a better idea of this being a defect or normal behaviour.
I know, it's kind a big ask so no rush! If you ever have time. I can do the same if anyone needs to see what I am talking about exactly.
Update:
I've noticed the issue occurs only if the lock screen is showing. If ambient display is on and the fingerprint icon shows at the bottom then the device will unlock without flickering. The fact that it's happening only when the screen is on at the lock screen, is what's making me feel like maybe it's not a hardware problem. Very odd issue...

Another update,
After doing more Googling I came to the conclusion that it's a hardware issue over software. I tried to factory reset and the issue was still present.
I couldn't update the software on the phone though. It kept telling me that there was an installation problem. I'm guessing that's because I had previously used a rooted EU boot img and a factory reset through the phone settings isn't enough to get rid of that. I'm hoping the repair center won't fault me for sending the device back with an unlocked bootloader. Doesn't seem like OnePlus would do that anyway, given how open they are with the modding community.
Once I receive the replacement of test to see if the issue was still there and will update this thread.

One time I sent them bricked device and they still accepted the return. Returning unlocked bootloader phone shouldn't be a problem.

What made you think it was hardware since I see other people have the same thing. Hell I had it too. I don't seem to have that problem after updating to latest firmware. Seems to be software to me.
Hope it gets fixed. I saw a thread for it on OnePlus community forum, so hopefully OnePlus knows.

Thinking it's hardware because my 8 Pro doesn't literally cause a white flash of the entire screen, it would just up the brightness which is normal.
And I was also noticing my touches only registered on more firm presses. Made me think it could have been a bad display panel.
Didn't want to take any chances especially while inside the 15 day return/replacement window.

Yeah good plan.

It absolutely does NOT do that on mine. Only the fingerprint area gets bright, not the entire screen.

+1 on the 9Pro

According to the OnePlus support section of the site, the progress shows as "Inspected". I assume the next step is shipping out a replacement. Hopefully it's soon, will post an update on the new unit.
Thanks for letting me know you guys aren't experiencing the issue, makes me feel good about my decision of sending it back. Almost didn't do it because I didn't want to come back to this Pixel 5 after being spoiled by that 9's screen size lol.

Got the replacement today, after some testing it seems like this unit has no issues! There is a clear difference between this one and my original. There was a blinding white flash even when using my pattern to unlock. Same thing when double tapping the lock screen to put the device to sleep.
This has no white flashes so definitely seems like a hardware issue. Finally, I can start enjoying this thing!

No it happened on any brightness. It was just more noticeable in low brightness and reading through the same issue on OP forums, others were confirming it is hardware related as a complete factory reset isn't able to resolve the issue. If it was software related, a complete restore would have/should have fixed it. Your issue might be different from what I was experiencing.
