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.

Sam problem here,
i called with HTC and they sent them to there repair centre.
Hey guys, I've had the Fuze since the day it came out. Never had any rough drops, only one onto carpet a while back from about 2 feet. Recently, the phone has been acting up though.
At completely random times, the phone will simply wakes itself up, for no reason. When I attempt to make it sleep, sometimes it wakes right back up, sometimes it stays asleep for a while. I can go days without it happening, or happening for hours straight. It will attempt to make itself sleep, but as soon as it sleeps, it wakes itself back up. It is a total battery killer. And the pocket dialing has become so much an issue I had to use a password lock, which I do not like and wish to do away with.
Here is why I think it is a stylus problem though. Whenever I take or make a phone call, the notes are up when I look at the screen when I go to hang up. It think the stylus is being pulled out, when it obviously isn't.
I thought it may be a software problem, so I flashed to a new rom, NATF 4.7. Still does the same thing. What do you guys think? I am thinking of maybe reflashing stock AT&T rom and taking it to them and seeing if I can get a replacement. But if I can fix it myself, I would much rather do that.
Hi,
I have this really weird stuff going on with my Nexus 5 screen. I cracked it a couple months ago and bought a legit replacement screen for it and installed it myself (glass, lcd and frame). I fixed it with good instructions and it worked properly for two months. However though, now when I take it out of a pocket and try to turn screen on, sometimes it just doesn't light up. It's still on and every button works but the screen doesn't turn on. I have to give it a light tap or two on the back in order to make it light up again. Same thing happens sometimes when I'm using the phone normally, the screen just goes black and goes on after tapping it couple of times. Otherwise the phone works normally like it did when I bought it two years ago and after running couple of tests with screen, everything seems to work from touch interface to the graphics card.
Tried looking it up, no results.
I've noticed that the front camera doesn't work for some reason (probably just broken) and the battery lasts in use only 2-4 hours which isn't that much of an issue since I'm looking for a new phone. I just want this one to last long enough till I buy a new one.
It comes up when tapping the screen or power button? It could be a power button issue.
The screen comes back on when tapping the screen or the back of the phone. The power button isn't the issue. The screen just goes black but nothing else happens. It doesn't turn off or go to sleep mode.
Strange issue. I've never experienced it and any problems I had were related to the power button.
Could it be a loose connection inside the phone? Maybe an issue related to the proximity sensor?
Thats actually what I've thought. I have checked the phone's insides twice and didn't see loose connections, and the problem feels like it's related to proximity sensor since the screen going black happens exactly same way that when calling someone or doing something else where proximity sensor shuts the screen. It's really weird though...
Huh, I took backplate off and unscrewed the motherboard cover and took everything apart and rebuilt it and now the problem is gone. Seems like there was just some bad connection somewhere.
Glad you got it to work without having to pay someone to fix it
So I took my phone out when I got home, and suddenly the touch screen wont work at all. I can still get notifications and phone calls, but cannot answer or anything because the touch screen just will not respond at all. I haven't dropped it since I used it last or anything. It just like... isn't working?
I think this might have happened for a little bit a while back, but it fixed itself really quickly... But this time its just not responsive. I've tried letting the battery die and charging it, and the soft reset of the phone many times to no avail.
My G flex 2 is on AT&T if it matters
Any ideas?

It looks that it's really not software problem, but hardware malfunction, so you should take your phone for repair.
Try a factory reset of no avail then prob a hardware issue are there any major scratches on the screen and be honest lol some scratches can interfere with the xigitizer
yeah no scratches on the screen or anything. Only thing I can think of is it fell out of my pocket as I got out of the car into a bit of snow and got a bit wet, It was in a case and thers no physical damage. It also worked after being wet and stuff. All I can think of is that some got under the screen or something later. It didnt stop working until about three hours after that.
also, a hard reset did not fix my problem. I really have no idea what caused this or how to fix it. I have insurance on the phone, so Ill just have to send it it.
Sorry if anyone else has this problem! I have found no solution
If I have my phone face down on a counter when it rings, when I pick it up the screen is black. Not off, as I see some light, but basically dark.
I cannot see who is calling...can't get it to display.
This actually happens a lot other times. Just now, for example, I just picked it up, and turned it on with finger print. I placed it face down, and picked back up immediately...screen black.
If I happen to have it on and brush the screen across my side, it will go black.
The ringing is the realy annoying one.
Any suggestions? I'm thinking it has to do with something about the proximity sensor sensing the screen against something...but it should let it come on when it's not against something.
Is noone else having this problem? Every time my phone rings, it turns on but stays black. I never know who's calling unless I answer.
I don't know what to do with it. Very annoying.
Hoping someone has a suggestion.
You could disable auto dimming on your phone. Use Lux from Play store instead.

Do you mean Auto Brightness? If so, that is not the problem. I have it disabled and am using an app for brightness control...not automatic.
I cannot find anything in settings about 'auto dimming'.
Thanks for the suggestion though...
You're right. I mean Auto Brightness, it does Auto Dimming too . B.t.w. I don't have this issue.

I'm beginning to think I am the only one.
Another symptom which I am thinking is related. Sometimes when I touch my finger to the fingerprint button to wake the phone, it comes on with that dark screen for just a moment. It feels like the phone is busy, overloaded, or just slow. It will then come fully on. Also seems like maybe it is just in deep sleep and slow to wake up. If I turn it off and back on, it is instant.
I check memory and it always has just under 1.5 GB free.
I don't know what to think, but it is very annoying. I thought about chalking Huawei support, but I'm sureo they'd just say to hard reset.
I do have a lot of apps on the phone, but with that much free memory I wouldn't think that should be a problem.
Another interesting thing related to screen dark: I can have the setting for display to not turn off if no actdivity to 10 minutes, and it still goes off after less than a minute. (Going off is different from the topic of this thread where it is near black/dark, but not off).
I discovered this while trying to use Huawei backup. Thinking of doing a Factory Reset. Instructions say to not lock the screen, so I'm trying to keep screen on w/o my having to hold the phone the entire backup.
This overall topic is making me pretty unhappy with the phone, which I had thought was perfection when I started with it.
sigh...
I finally called Huwaei technical support this morning. They apparently know about this problem, and want me to send the phone back for repair. They expect me to be without a phone for two weeks while this is going on.
It speaks to the reason to not buy phones away from carriers, as anytime I had a problem with my Samsung, they would send out a replacement and then I would send back my old one and I would not have to be without a phone.
Pretty poor .
AN update In case anyone is following this for some reason...
Getting ready to send the phone in, I did another factory reset. I had got to wondering if maybe Gravity Box had been part of my problem. May be the case...not sure. But for now i'm not having the problem. I changed some of the settings on it when I reinstalled. I cancelled the return.
I've had the odd time when the screen is on, but not properly backlit. You can just about make out the screen, but then the backlight seems to rectify itself. It isn't just the Mate 9, but the P10 and probably other phones. Doubtful a hardware issue I'd have thought - rather a software glitch.
The P10 just got an update earlier this week (yet still with April security patches) but my Mate 9 hasn't had an update in months.
