Unlock screen unresponsive - Huawei Ideos X5 U8800

Put down the torch; I've searched and read the other threads regarding static buildup and screen recalibration.
On my stock Ideos X5, the screen lock is unresponsive if the camera app has been running when the screen is locked or auto-locks.
While trying to document the issue, I think I found a fix (and a bit of insight into what's happening).

When the phone is flat on a desk (so not receiving any video input), the unlock screen responds as expected.
When the phone is held normally and the camera is operating behind the lock screen, the device is painfully slow to unlock (for the swipe-to-unlock screen, pretty much impossible).
Would be interested if anyone can reproduce this on other devices.
Lock and unlock your device; note how it works normally.
Start Camera and lock device.
Holding phone in air, try to unlock device. Note responsivity of unlock screen.
Put phone flat on desk (so camera is blacked out, ie not on a glass desk ...). Unlock and note responsivity.
Repeat until you're convinced I'm wrong, or right.

Huawei better be looking at these forums!

Probably this is caused by the video overlay driver (mdp4_overlay).

If you can reproduce this behaviour, please say so. Otherwise Huawei (and I) will assume that the problem affects only one crazy guy on the internet (me).

Yep, my huawei acts the same way.

Just a quick note, in solving my issue with the touchscreen. It turned to be that when the GC (garbage collector) ran it would drop input to the touchscreen. Its quite possible that its running every couple of seconds when the camera is on (likely a bug).

mine too..

I have had the same problem a couple of times now. Both times the phone rang and I couldn't unlock the screen to answer it. I think the problem was that I was running an app (last time it was Aldiko, not sure about the previous time but I'm sure it wasn't the camera app) and it auto-locked while the app was still active. I've never had the problem occur when it auto-locks from the home screen or if I sleep it manually from the home screen.
It seems to be more than just the camera app that can trigger this problem. Maybe it's having any app active when it goes to sleep?

I watched your video, tried several times but I cant reproduce this bug!
Perhaps some app causes this..
My X5 has Wind GR Stock ROM.

Just tried it and can't reprdoduce this bug either.
- Start camera app (either in picture or video mode, makes no difference)
- Hold the phone vertically in air so that it “sees” something
- Lock phone with button on top
- Wait a few seconds(still holding it vertically).
- Turn on phone again to luck screen
- Unlock phone
Works without a hitch!
Huawei Ideos X5, bought in Germany four weeks ago, stock Android 2.2.1, kernel version 2.6.32.9-perf

i can reproduce it. also bought in germany kernel version "2.6.32-perf [email protected] #1"
good to know how to "solve" the problem because i had it once and didn't know what ic could have been

I can reproduce this issue (!) and my Huawei u8800 is 2.6.32.9-perf on Android 2.2.1. Interesting that the results seem to vary ... I wonder what else it could be.

is there any solution to "screen can't switch on"?

at the begining , my HD is fine.
But , after 2month , the phone has some rotation problem( it doesn;t matter, as you can solve it by pressing the on/off buttom )
But now, the phone's screen can't switch on, when i touch the four buttom on the surface of phone, it still vibrate..just i can't switch on the screen"
i have already tried all the things like take out the battery, press the reset buttom... the problem still occur,
Screen can sometime turn on luckily~
but, if the phone's screen is switched off for a while, the problem still occur..
can any professional heal my phone?

Obvious questions: Have you tried a hard reset?, Diff rom? Have you loaded up anything weird that mighta casued issues? If it will do a hard reset then do it. Start from scratch. If it works then be mindful of what you reload it with. If that doesn't get it, try a diff rom. At this point you got nothing to lose. Will it go into bootloader mode?
Battery comes to mind also. Have you run it down to nothing? Sometimes that will affect the charging capabilities. When the screen is dark can you still hear sound? Def do the HR.
My suggestion would be, to give the HD to your reseller and get it fixed.
I have had the same problem, and as my HD also didn't connect to my PC anymore, I send it in, and got a brand new one, because they couldn't fix it. Make a backup while you can, because the problem will get worse over time.
Likashing, the same exact thing started to happen to me a couple days ago. I've hard reset and flashed a new ROM. It seems that the problem is intermittent. After I just let the phone sit for a few minutes, the screen will come back on. It makes me wonder if this is heat-related issue. Anyway, I'm screwed, because I have no warranty since I bought it from a guy in Australia (I'm in US and needed the T8285).
I'll definitely be keeping an eye here to see if there's any resolution other than repair.
while the screen does not turn on, have you maybe tried to use another phone to call your HD and check if the screen turns on when the call arrives?
maybe if the screen turns on it's more a software related issue (so hardreset et cetera might be worth a try), if not, i fear it's hardware

...i have no warranty too....
in Taiwan , there are couple of people have these situation, the maintenance staff working Htc, said that it is a motherboard problem or the screen problem...but i wonder that why only few people have this problem. My phone is completely fine before i flash the HSPl1.56OLINEX.but when i try to flash back to Hspl 1.4 , the problem still happen.....

Exactly same problem here
HTC purchased in Sweden.
Cant switch screen on, when incoming calls come it rings but no screen alive. Vibration when pressing the buttons at bottom. And the low battery sound i can here when low on battery.
When connecting it to charger the orange light at power button will not light up (orange) as usually.
My problems started when i had the HTC in my jacket pocket, a VERY rainy day, so the phone was moist OBS not wet. Thats what i beleive ghappened to my phone.
And now i can not find the purchase receipt to the phone
It might be entirely unrelated, but the screen on my THD also had the same problems immediately after a few flights from coast to upcountry 1800m elevation during summer. The system powered up but the display remained off, and no amount of fiddling would switch it on.
The first time it took a few hours and then spontaneously corrected itself. The second time I had to remove the battery for two days, and then all was fine again. Only happened after flights from coast in summer. It hasn't happened again, but then it's winter here in the southern hemisphere.
I suspect condensation, but that's only a guess...
I have the same problem too here in Australia. It started with the screen not turning on but the buttons still work. Then you'll sometimes notice the screen is inverted and upside-down.
I've sent mine in for service. Haven't got it back yet but I understand the motherboard needs to be replaced.
In short, this is definitely a hardware problem and if you look around the discussions on the net, this is slowly becoming quite a common problem with HD.

Yes exactly, I have had the upside down screen too! Well at the very least it is good to know that people are experiencing this problem other than me. I love this phone so I will have to pay to for the repair. If anyone here has any idea or estimate of what this will cost, please share this here.
The problem for me was the moist, after three days it started to react again... And now it seems to be working...
I guess the air up in the mountains are moist... maybe...

So then that's two people so far (including AFW from the first page) who have said that after some situations involving moisture have passed, things are back in working order. I hope for the same to happen soon.
so it is due mainly to wateR?

I doubt it is related to water. My device never gets near water or moisture and still experience this problem. I do wonder if it is heat related as the device can get quite hot during charging and perhaps cause the motherboard to play up after a while.
btw, does any of you use some sort of plastic/silicone cover. I wonder whether this type of cover blocks the heat from dispersing.
As i understand it, so far only people who have flashed a different ROM (and with it maybe radios) to their device. If it's a heat issue it could be something to do with the radio version. I have tried different radios and there was one in particular that heated my phone up like crazy while i was listening to music without the screen on (but i don't recall which one it was).
I only used stock rom and never flash my device and still have problem...

I do not have any type of cover on mine.
I agree with the possibility of it being a heat issue though.
Very perplexing. This past weekend I again travelled from Joburg to the coast (from 1800m elevation to sea level), and again the THD screen stopped responding to input whilst at the coast. I desperately fiddled, reflashed, hard reset at least 10 times to see if I could get the screen to work, but it always booted up locked, and no amount of fiddling would do anything. I even put the thing on an oil heater for a few hours, hoping that if condensation was the culprit (my current theory) then a goodly dose of heat would at least evaporate any moisture, and once, for about a minute the screen responded, and then again went dead to touch. I had to use another phone all weekend. This evening, on returning to Joburg, I resolved to get another device, maybe the Diamond 2. After a few hours back home I retrieved the THD, put in the SIM and, lo and behold, it worked fine. This is most vexing, but I fear the THD will have to go -- I just can't live with this unreliability. Sad, really, because I love the big display, I love the fact that guys like Throy are cooking good ROMs. In many ways the THD is about the best out there, at least for my needs. But that &@&* thing has to be reliable.

[Q] phone shutting down whilst screen lock

has anyone faced the phone switching off even when it's screen locked? This happened a few times to me.
1st scenario is when my phone is in a waist pouch which is a little tight for this model. when i take it out of the pouch, i either find it off or waiting at the sim unlock screen. this is caused by pressing the power button accidentally.
2nd scenario is after charging over night, i wake up to find the phone asking me to key in sim unlock pin (it will not be completely off because whenever charger is plugged in, it will power up). The phone was screen locked before i charge it and i did not touch the power button by accident unlike scenario 1.
which ever the scenario, by right the power off button shouldn't work whilst in screen lock right?
The same scenarios happend to me, sometimes more than once a day. Very annoying.
I too have this issue, especially the overnight charging one, which is annoying because then the alarm fails to go off!!! After convincing 2 other people to get the Trophy 7 they also experience this.
I called HTC support in the UK yesterday and all they could suggest to me was that I reset the phone settings, which I've done, and of course ended up needing to put all my settings back in which is extremely frustrating when I expect that it won't fix anything.
I really would recommend calling HTC support in your country and logging a call, because the guy told me that I was the first to report it.
You can get the phone numbers from the htc website, which i cannot post the URL to since I'm a new user, but I'm sure you can find it. Go to "Support" -> "Customer Service" -> "Support by hotline"
Of course, you could not call them to report the issue, but then they'll think that I'm the only user in the world with the problem and not actually resolve it!!! It's going to take you about 10mins and they'll keep talking to you about windows mobile 6.5, instead of windows phone, but the more calls logged = greater chance of resolution.
I've had the turning of when it's in my pocket, but i've never had it turn of overnight when charging.
at least not that i've noticed
Whilst experimenting with android on my touch pro from the very beginning when you couldn't enter a sim code, i've removed it and i'm to lazy to set a new one
All the problems (screen freeze of crazy dancing icons of phone shutting down) solved after FLASHING newest WWE ROM from this forum. Maybe helps, but U have to decide and do it yourself or not.
This has happend MANY times on my trophy aswell.. I ended up turning off the sim lock code (That way the phone starts up again after boot and your alarms etc works)
Yup, I've had the "pocket" thing also happen to me, more than once in the same day... quite frustating.
Qtek S200 (HTC Prophet) After ROM update, its now shutting down whilst in sleep mode
Sorry to dig up an old thread, but recently I upgraded my s200's ROM using the CD utility that came with it. Its now running Build 14928.2.2.0 of WM5.
Before the ROM update it has never done it once.
Some people said they got the problem when it went into lock screen, my lock screen is fine. It will only do it when the phone is in sleep mode, if i disable the "power off" timout setting then its absolutly fine aslong as i dont press the power button.
Did anyone ever find a solution to this problem?
Somebody did mention about flashing the rom from one of OS's on this site, but all the ones I have found contain dead rapidshare links.
Any help appreciated
Thanks
My solution on Trophy is simple, using a Casemate case on my phone. It makes the off button so stiff, that it's hard to shut off.
I guess I never realized why it was such a pain in the case to shut off... this MUST be the reason. Also, since I now have two Trophy's (one for developing roms), this other one I just bought has been through hell, and it's difficult to half press the camera button to focus. The Casemate case I have on my good Trophy makes it far harder to press the camera button, but my year old Trophy that I've always had doesn't suffer from any problems with its camera button.
This is the newer version of the Casemate case I was using on my HTC Trophy. I don't know if this will help you with your older phone, but maybe Casemate makes a case for it. Since it's an older phone, it will be difficult.

[Q] LE E900 Unbranded AT&T USA touchscreen NOT responding! PLEASE HELP!!

I really like my LG E900 phone. I bought it for AT&T in the USA unlocked on Amazon. Installed Mango recently with all the firmware upodates and until today been having a lot of fun with my phone!
All of a sudden today, the touch screen seems un-responsive. The touch screen works intermitently. It starts to work then stops again. I have tried resetting the phone (have to pull battery). I wasn't doing anything when I this happended. I recently installed Tango and Livestrong mobile app, otherwise phone was flawless.
1. Is my touch screen broken?
2. Does anyone have a clue. I thought maybe the phone is running apps in backround but I can't seem to find the problem. The battery seems to drain also.
3. The phone does become operation for minutes at a time but then goes bad.
I wanted to add that the screen is also very slow at first then starts to respond normally. Almost seems to something happening in the backround. As of now, the screen is still not responding. If I continue to play with the screen, sometimes the screen starts to respond, but slowly.
thanks for help!!
In your position, I would try to:
1. Use the guaranty (if it's still active) and take it to a local service
2. Flash a different rom/firmware with all the latest updates inside and see what happens.
3. Buy a new e900...they cost less than ever nowadays...(almost 180€-190€ without a contract...)
You have got to be kidding me, the exact same thing is happening to me, and for 2 days now. I'm unbranded (I believe) on Vodafone Spain. The entire phone has become unresponsive. Drops nearly every call, has rebooted about 50 times in the last 24h.
fUnny thing is, it doesn't ever reboot when I'm actively using it, just during lock screen.
cOuld you further develop your symptoms just in case we have the same issue? Thnx

More Detail about the LG E900 WP7 Lock Screen issue
OK. SO here are the symptoms-
- Whenever I enter the lock screen, the touch is screen does not respond. TO be clear the touch screen senses I am touching the screen but the lock screen doesn't move when swipe.
Ater some research you can find the SAME EXACT error on HTC Surrround Samsung Focus. here's the youtube video. exactly as it appears except time to unlock takes about 2:30 (2 minutes 30 seconds) on my LG
http://www.youtube.com/watch?v=t3QABdcTINc
So here is what happens and what I do
1. Again entering the lock screen, and attempting to unlock the touch doesn't reposnd to any swipes.
2. You continue to swipe and occasionaly hit the physical buttons. This keeps the lock screen on. You have to keep swiping for about 2:30. After 2:30, the touch screen just seems to respond.
3. After the touch screen responds. Nothing out of the ordinary. When I tried using IE, it seemed that IE didn't work as well. Pinch to zoom, swipes not as good. Also portions of the screen are not as responsive.
So maybe start looking for a replacement.
I've tried
- restoring previous OS and files. No change.
- Hard and factory reset. No change.
- changing the brightness setting (AUTO, low) no change
The only thing that I haven't done is upgrade/downgrade the firmware. I think that may help but not clear on what to do.
Are you using the correct charger?
I have an HP Touchpad that has a high output microUSB charger for rapid charging of the Touchpad's battery. Although it hasn't (yet?) given my e900h any troubles, I did read at least one report of a guy's Samsung phone reacting poorly with symptoms similar to yours after using the Touchpad's higher output charger.
I am using a third party USB charger. Not a high power one, but an inexpensive one from monoprice. Ok, I will try.

Some people have reported errors and crazy system behavior when using third party chargers...
Still no luck. Using stock charger now. Will wait to see if any improvements. Thanks everyone.

I was one of them. This behaviour would occur with the charger connected.
I get the feeling the problem the OP and I are facing is also related to chargers, but no longer when they are connected. Charging makes no difference for me, the phone is still reacting very strange.
More Info on failiong touch screen
So
Here are more precise deets
- Whenever the backlight is turned off, the touch screen becomes non-responsive
- The touch screen notices touch but not swiping.
- in order to get the touch screen to respond you must continue touch the screen for 00:02:30 (2 minutes, 3 sec).
- the touch screen will usuallly start to respond to swipes but only a single axis (e.g. vertical or horizontal)
- after 2:30 the touch screen responds like everything is ok.
- the goal is to make sure the screen backlight stays on until the for 2:30. In some lock screen cases, you can issue a voice command, camera etc which effectly keeps the phone one (i.e backlight on) for longer without having to continuously touch.
- issues came after tangoi install and livestrong install.
- wonder if tango did something to lock screen
- also tried changing lock screen wallpaper - no changes
- when installing microsoft insider app, I tried using the wallpapers, but the apps crashes. Changing wall paper using default app works
- using default charger no changes
- received the latest update (fixed voicemail and outlook issues) - no change
I haven't been able to retore/flash NODO. That is probably what I need to do.
same problem here, new phone, original recharger and touchscreen of my optimus goes sometimes frenzy...the frequency of strange behavior raises when I fully recharge battery
i found a video on youtube, but yet i cannot send urls, because i'm new user here, u can find it if u search "problema telefono"
any1 have some solution, pls? or did u try to send the phone back to LG service?

[Q] momentarily unresponsive touch screen

Hi guys
I have moved from iPhone to a note 4 and loving it!
I was just wondering if anyone has found the touch screen occasionally doesn't respond to their touch and you have to touch it again. On the iPhone it only ever missed a touch if my finger was in the wrong place, but it never happened on the keyboard. Every so often maybe 5/6 times a day I touch a key on the keyboard and nothing happens, when I try again it's fine. I can't reproduce it, because when I tap anywhere on the keyboard something gets pressed. I was just wondering if this was normal?
Hope you are enjoying your phones!!
Anyone?
It's most likely cause your palm is on the phone. One of the downsides of a slim bezel on a big phone. Also keep in mind if your spen is on the screen, your fingers won't work. A case might help.
I thought about another part of my hand touching the screen, however with half my hand layed across my keyboard I can still type with the other hand. Thanks for the response
I Pele tried factory resetting today and not installed any apps, but it is still happening
I rang Samsung this morning and they advised I return I to the store and get an exchange. Luckily my local store got its first batch of note 4s in this morning and they swapped it out. I restored it all firmware updates put on it and now works fine! The only thing I haven't installed is a Google play system update thing. I was wondering if that was the cause x
Similar issues
I've had similar issues (in fact, that's what brought me here in the first place). Initially, I was able to tap on the screen in the text box and then continue typing (I use Swype). However, now my messaging app (default Messages) just freezes up, forcing me to close the app, clear the memory, and relaunch the app before continuing.
Were you using the default app and/or Swype when you had issues? I'm going to try to factory reset my phone to see if it helps.
It's taken a couple of weeks for this problem to develop, so please keep us posted if this problem arises again on your new phone!
Edit: Also want to point out that when I text, I use one hand to hold the phone and only a finger to swipe my text. As such, only the one finger touches the screen.
unable to use touch screen. only hard key were working >>Note4
Hi everyone,
today i just had the same problem with the touch screen. no response at all .. after i tried and took out the spen .. and surprise it worked with the pen.

Same thing happened to me last night. The touchscreen became unresponsive while using chrome. The phone was a little warm but not bad. I didn't try the pen, sounds like a good idea. I am not certain it was a touch screen issue with mine. Almost more of a processor issue. I got the phone to lock. After pressing the menu or lock button to wake the screen it would take 5-10 seconds to wake. Then I could swipe my unlock pattern. It would not show any lines. I would wait, the screen would turn black after timing out in about 5s. The about 5s after I could hear the speaker make the unlock sound. I ended up doing a battery pull and that fixed the issue. Anyone else have something similar?
Should I try and replace it?

Observe to see if it happens when you're using other apps too. Chrome has been notorious for causing all sorts of problems, like reboots, freezes, etc on some devices.
Also it may be worth installing Chrome Samsung Support Library.

Got the same problem after 2 months of normal usage... I initially though I had installed a third party application which was causing the system freeze but this was not the problem.
- tried factory resetting and not installed any apps, but it is still happening
- When this happens if I take out the spen .... surprise it work. The pen allows me to do anything... But the touch screen does not work with fingers...
- I used the pen to reboot the note4... Still the same problem after reboot... I ended up doing a battery pull and that fixed the issue for.... a couple of minutes... Then the problem came back....
The only solution remaining was to return the phone.... They gave me a Note3 while my Note4 is being repaired...
That's a shame for a product of that price!
:crying:
Same thing is happening with my 2 months old note4 since two weeks ago. An horizontal line 1.5cm in width about 1/3 from the bottom of the screen, became unresponsive. At reboot it works sometimes then it becomes unresponsive again. It looks like in the image I attached, the difference is that the area is horizontal, not vertical. I'm taking my note4 to the store today for warranty, hopefully they will replace it. I haven't abused the device in any way, I have a screen protector since its first day.. I really hope this isn't a serious problem that affects many users.
Just like some of you mentioned above, the pen has no issues on any area of the screen.
Cheers!

- When this happens if I take out the spen .... surprise it work. The pen allows me to do anything... But the touch screen does not work with fingers...
- I used the pen to reboot the note4... Still the same problem after reboot... I ended up doing a battery pull and that fixed the issue for.... a couple of minutes... Then the problem came back....
The only solution remaining was to return the phone.... They gave me a Note3 while my Note4 is being repaired...
That's a shame for a product of that price!

same thing happen to my note4 today. the only difference is that yours was fixed for a couple of minutes after removing the battery. my note4 wasn't fixed after that. Only S-pen works, touch screen with fingers wont work. you mentioned you're note4 is getting repaired, did they tell you what may have happened to it so that i'll get an idea of the cause..
You found the appropriate thread, I was just now going to share the link to this thread with you as well as quoting what others experienced,

Never purchase a device without a return / DOA policy. Not worth the hassle. If it hasn't been 30 days, you should call your credit card company or Paypal and place the amount on dispute, wait, you purchased from another market, please tell you didn't pay by cash.

I have this problem after I flash CWM recovery, before this was flashed with twrp recovery, I reflash stock rom with odin, I flash many times CWM and TWRP and I still have the problem, my warranty it's void now but I think to go at Samsung store to see if they solve my problem. This problem look like a driver for touch corrupted, if somebody find it out how to fix or have any ideea please weritte here, thanks you
I've started to have this problem as well, lower part of the left side of the screen sometimes registers touch instead of scrolling! Very annoying, tried to update recovery, tried tapping screen, doesn't help. The worst thing is I cannot reproduce the issue at will... It seems pretty random.

Unfortunately, if the phone is on Verizon, the dialing codes will be disabled.
Potential fix.
Please excuse the necropost But I came here looking for a solution from google and others may too. I found a way to solve this issue/s.
There appear to be two issues affecting this.
1. Overloading the processor.
2. Static.
If your touch input is lagging or doesn't register at all but then suddenly does a few moments later, its likely a type 1. problem. I fixed this by disabling resource intensive features such as s voice. This also improved battery life and overall performance considerably.
If touch simply doesn't work at all, but s pen works fine then the problem is more likely type 2. That being static buildup in your person. Simply touch something that can ground you and it should fix the issue. A metal tap should work. Be wary, you might even get a little zap as you discharge

Oneplus 5 Black screen after replacement

My OP5 screen had a small crack so I decided to repair it. After following the tutorial on youtube step by step the phone powers up fine. But as soon as the screen goes to sleep, it get stuck in black, although it feels like responsive (Ican hear the clicks and vibrates and all) but it wont wake up

Could you wake up the screen? Maybe it's a connection problem or related to the proximity sensor?
Did you ever find a solution to your problem? I have exactly the same problem, but it happens only with Android 9.0. Oreo seems to be working OK, but as soon as I upgrade to official 9.0, the screen won't wake up from sleep. The backlight turns on, but the screen stays black. The phone works OK as long as I use it, but if I press the power button or let it to enter "standby mode", it will stay that way (off). I suppose it has something to do with the replacement screen, but since it works with 8.0, I wish there was a workaround to get the LCD to work with Pie too.
Same problem here. Replaced display too.
I've had a similar issue with a different device before (ZTE nubia Z7 mini). I replaced the screen and it would work correctly, but when I booted TWRP, I would get a black screen. I figured that because the replacement screen was not an OEM one, it may have something to do with LCD drivers in the recovery. I used the old cracked screen with the device opened up to navigate in the TWRP recovery, and I flashed an newer/different recovery. Voila, the new recovery worked with my replacement screen. Based on this experience, it may just be an LCD driver compatibility issue with the replacement screen, causing the screen to just go into forever sleep mode. The driver may need to be changed or tweaked in the Pie version for your replacement screen to work with it. Just a thought, not fully certain.

You're probably right about the driver issue. My OP5 has no problems whatsoever with Android 8.1, but 9.0 won't work no matter what I do after waking up the device. The backlight turns on and and off for a few times after which nothing happens. The phone is still working normally, but it's in "blind mode" (music will continue playing, volume buttons work...but they're kind of slow and laggy) Too bad that the latest update (9.01) didn't fix this issue either. I really wouldn't hold my breath getting this issue fixed anytime soon (officially) as it seems to be a cheap 3rd party screen problem.
edit: I tried the custom recovery (20181227) and the same thing happens there. Once screen goes off, it won't come back on.
Edit 2: gave up on the replacement screen and ordered an oem lcd. Lets see how it goes.

Do keep us updated if changing the display again fixes this issue. Would be interesting if someone had a fix for 3rd party displays but as of now it seems that's highly unlikely

Sure.
Got the new OEM amoled screen today. It's brighter, more responsive and doesn't get stuck (black screen) with Android Pie. Problem solved. Price was 3 x higher than the cheap 3rd party screens, but definitely worth it (around 80 euros). All screen gestures work as well.
Bought it on Witrigs (https://www.witrigs.com/oem-lcd-screen-assembly-for-oneplus-5-midnight-black). it came really well packed and arrived fast (7-10 days to Finland). I highly recommend this screen and Witrigs to everyone
Also changed the screen from a friend and have this strange behavior, that the screen won't turn on .. only when I reboot or double press the power button so it launches the camera - the delay tho is about 7s, which is insane! you guys think this is the screen problem, or did I damage something and if yes, what? I repaired about 100 phones in total already ..

Sounds a lot like my OP5 with cheap 3rd party screens which would hardly work at all with Android Pie. If your friend's phone is running on Pie, try downgrading it to Oreo and see if that helps. My phone worked moderately with Oreo but not at all with Pie (wake and touch issues). Currently my OP5 is running Android Pie perfectly with the screen that I bought on Witrigs.

Bizarre, have you tried the usual factory reset / rom reflash? If you confirm that its not a software related issue, then it probably is just the screen if its not an OEM part. Can't see what else would be the issue here unless there was other kind of damage before the repair maybe
Like @sbasil mentioned, it could just be due to the non-OEM screen being incompatible with Pie drivers.
Thank you for saving my phone

Mine not working with lineage base rom but is good with last pie 9.0.8. Did you try it?
Have this issue too
My OP5 has its original AMOLED screen. Running OS 9.0.8. This started happening after the most recent update. At least I never noticed it before.
I ran *#808# diagnostics, thinking maybe it's the proximity sensor, or the fingerprint scanner, but everything passed.
Also while locked, ambient display works. It's just getting the Home screen to appear after waking the phone that's become agonizing. And it does wake, the touch screen is responsive, it's just completely blind.
I mean consider this: I can take a screen shot, a screen shot, while the screen is in ambient display and the screen shot is of the home screen.
Pressing the power button or home button or notification slider repeatedly sometimes coaxes it to appear, but the only sure way to get the Home screen back is to restart the phone.
I had a black screen issue after changing the screen to an OEM AMOLED one, and after tearing my hair out for a couple of hours, I discovered that turning off " night mode" fixed the problem instantly
Same happened to me... cracked screen, purchased 'OEM screen' installed. Some apps work, some just black screen.
Driver issue? Running Pie 9x. Anyone had success with this by dropping back to Oreo? Would it do anything different to flash the Pie Firmware?
I repair/upgrade OnePlus 3/3T/5/5T phones to donate to families in need at the local family shelter. Some of them have lost or had to sell their phones just to get food and such. Now they need one to arrange job interviews and housing, things of that nature. So anyways, all that to say this.... I have replaced a LOT of displays, and all of them were the 'cheap' ebay variety. Each and every time I would replace the display, the phone would act just as described in this thread.
After long hours of reading, searching, and experimenting, I have found the ultimate and final solution to this problem. The answer to this issue is simple, but was not so simple to find. Whenever anyone does a screen replacement, and the screen is not the high-priced OEM variety, their phone will almost always have extreme difficulty in waking. The fix, and it has worked for me 100% of the time, is to flash a custom kernel. For the OP5/5T the kernel I use that always works is the Affinity kernel. Just flash and forget. The phone will always wake up after you flash that kernel.
However, don't forget, that what also happens with these lower priced replacement screens is that you can no longer double-tap to wake. I still haven't found a solution for that problem, but it always happens each time I replace a screen. The kernel won't help with that. But it does fix the 'won't wake up' problem.
Try it for yourself and see. You will be happy you did!

I'm not clear about what you are asking. What exactly are you calling FW?? Some people mean radio and camera firmware. Some people mean the custom rom that gets flashed. What do you mean?
