Huawei P9 screen flickers when trying to unlock - Huawei P9 Questions & Answers

Help please!!
I got the Huawei P9, when phone is near strong sunlight the screen illumination is very weak, but at low light it worked fine.
But now it got worse, I can't even use my phone (in any light condition), when I unlock it the screen is showing for 1 sec and then the lights goes weak (can barely see the screen) while the touch works fine.
When I start phone in safe mode - it works great with out any issue, might be software issue.
I have disconnected battery and restarted - didn't solved it
I tried formatting and restoring to factory but it doesn't fix it - restoring to factory I get android 5.1, when I bought the phone it used en older version, so I think that the factory version in my phone is also messed up.
It search for new ROM but couldn't find the right one for EVA-l09c576b386
I also suspect it may be a sensor issue, can I calibrate the light sensor?
I found a youtube video of the screen flicker issue just like mine (sorry, I can't send here links yet).
You can see it searching "Huawei P9 screen issue (Automatically blackout)" in Youtube
Any ideas please?

Have you tried with Auto Brightness off?

That is correct friend, my only explanation for that is that online phone upgrading also updated the factory ROM image.
I search for my real factory ROM, but didn't find any for eva-l09c576b386 ,
I got the feeling it will solve the issue

I can't say that I experienced that too. But I will keep an eye on it for the next couple of days. Maybe I just didn't notice it.

ah when it does happen you will definitely notice it
you hit the power button, but the screen stays black
although i can confirm the phone is on, because if i plug in the charger, the light turns orange

press and hold the power button to see if it comes back to life, sometimes I get this on a .569 custom rom and have to either hold power+volume up to reboot it to get it to work

I don't have your problem but I did have times yesterday where it would flash me black screens for no reason, for example when trying to close open apps, it would just flicker black for a bit. Haven't had that problem today though. I do however have broken Wifi at the moment, I can no longer connect to any network or access the settings without the settings freezing.

camera lag
I have the camera lag. when I open the camera app it takes complete a second or two to open. and if you open it from lock screen it takes for ever. well at least from the lock screen it was laggy on .569 too. other than that the UI is slightly slower and laggy than .569.

auto rotate not working 5.0.1

Hey all, i recently flashed the factory image for 5.0.1 and all of a audden auto rotate stopped working. It did fall put of my picket from about 3 feet onto the ground. Nothing externally was harmed . however, i cant remember if i had issues wuth rotating the screen after flashing the factory image and before i dropped it... Im wondering if anyone else has experienced this from either a physical drop or from a bad factory image flash. Thanks...

I am having similar issues, however, my device was not dropped nor was it flashed. The last thing I remember doing was turning the phone to landscape to watch a youtube video, then when exiting the video to select a new one it would not rotate back. I didnt think anything of it at first, but then when I couldnt rotate videos to full screen I became suspicious that there was something wrong. Checked other apps to see if they would rotate, no dice. I have checked the sensors with "Check My Android" and they are all working fine, however, the calibration is way out. I have also rest to factory settings, and the issue persists.

---also yes, i toggle between rotate and non-rotate and the issue is still present.
sadly after a factory image install, auto rotate is still not working
EDIT: TRIED AGAIN AND AUTO ROTATE IS WORKING... but now my cell service is not working. I'm chalking it up to a bad factory image download and trying yet again....

I had a conversation, with Motorola support and they seem to think the only option is repair/replace. I will be speaking to a memeber of the aftercare sales team tomorrow, ill update tomorrow.
Hey I'm having a similar issue, I bought my nexus 6 in mexico no more than a month.. Today it slipped from my pants and felt screen down.. Had a few scratches but nothing to bad.. Well I haven't noticed that after the fall my auto rotate is not working.. Camera, videos, photos etc. Nothing auto rotates, the only thing I can see in landscape is YouTube because of the option to see it on landscape.. I don't know what to do, I have re booted the phone 3 times and nothing.. I'm thinking in installing the firmware or something like that but I need some help with it.. I don't know if someone can help me this???
Having both issues.. No auto-rotate and I've lost all cellular connectivity. Wifi works fine though. The heck is going on?
Has anyone else found a resolution to this?
All of a sudden mine decided to stop rotating earlier today and even though I can toggle it in the quick settings, nothing changes. I've since rebooted a couple of times but no luck so far. I'm on 5.0.1 by the way, non rooted, straight out of the box.
Edit: I've downloaded "Accelerometer Monitor" and confirmed that the accelerometer is responsive in Y,Z axis but the X axis was flat lining. I gave it a gentle slap onto the palm of my hand and all of a sudden the X axis jumped to life. It's as if the axis was stuck or something. It's responding now, though I have still had a few strange issues, like apps going to landscape when the phone was being held in portrait.

Screen gets darker in some apps

I've got p7 l10 with emui 3.0 b609. And I'm experiencing 2 issues:
1. In some apps (Firefox, chrome, sms bulit in app) screen goes darker when app is opened and goes back when its closed or just minimalized. I've got auto brightness off.
2. Bluetooth is turning on by itself. I'm not sure if it's happening everywhere but it happens very often while using chrome.
Help!
Hi. For the first issue with the screen: in phone manager in power saving what power plan you have selected? Normal or Smart ?
In Mate 7, I have the same issue with the new firmware b125 when the selection is on Smart when browsing the internet. But if I change to Normal, the brightness of the screen remains the same all the time, so the.issue is gone. You can test it, maybe it's the same for you.
In the previous firmware b120 this issue it's not present under Smart selection, so it's the new firmware with the problem.
This is it. I was using 'Smart'. Now on 'Normal' that is not happening. That solves the first issue.
However bluetooth is still turning on by itself

Nice . I'm glad that this 'fix' it's working for you also. It's from the firmware and I don't know why huawei did this change, it's annoying.

I don't have this issue with bluetooth. Some quoestions/possible solutions:
1. Did you try to reinstall Chrome?
2. Did you try to restart your phone?
3. Did you try an factory reset?
4. Maybe you have an app/game installed that could turn bluetooth on automatic?
Beside the brightness turning darker on browsing, b125 firmware for my mate 7 had another issues and I made an downgrade to an previous version which is more stable ( the one that came with the phone b120). Maybe you can try an downgrade to a previous version for your phone.

1. Only reinstalled updates cuz no root.
2. Yup
3. Nope
4. I don't think so. As I remember problem appeared pretty soon after installing b609.
Today also bluetooth turned on by itself outside chrome, so I don't know anything now. But it's very rare outside chrome and very often inside.
I don't want to downgrade. Previous version is previous emui and I love emui 3.0.
A little update: from some longer time problem no longer appear. Maybe some of chrome updates fixed something. I have no idea. It may be a mistke, but recently my wifi turned off (happened two times in few days). It could be a missclicking while using options panel, but who knows

Lag When I Unlock The Phone

Hello after i updated my phone to oreo it lags sometimes. I assume that it is kind of a Glance problem cause when i turn off glance there is no lag at all(pretty strange i know). I contacted support about this 2 times and they said restart the phone and clear the chace of the app that causes the issue. Neither of them work. Does anyone else facing this issue?

The only lag I have is with the fingerprint senzor. If I doubletap the screen and then I press the fingerprint, it unlocks instantly. If I press the fingerprint with the screen off, it takes a while before the screens turns on (~1.5sec). Maybe this is how it is on the Nokia 8, but on the HTC 10 was lightning fast.
I will reset the phone if the problem presist s i will send the phone to service

Had a 10 as well as don't really notice that much difference. What I will say is that battery performance trounces the 10 so I'd imagine it's pulling the Nokia from deep sleep that causes the minor lag.
always restart wherever it lags. it lags with the amount of oreo update.
Did you tryed a factory reset? I did it and it is more responsive then before. But safe needed data first. Backup before factory reset!

I think it is so the phone isnt getting false attempts to unlock it, only my opinion though, i am not saying that is deffo the reason.
I just have the same problems with my Nokia 8 since 2 days.
Fingerprint or power-button unlock is sometimes painfully slow. Maybe up to 5 seconds.
I have the Android 8.1 Oreo update installed since some months already and also the newest security patch.
I have read, it's a general problem of the 8.1 version, that unlocking gets slowed down.
Anyone has a solution so far? Factory reset doesn't seem to help always (I didnt try), but maybe downgrading to Android 8?

No, this didn't work for me at all.
I think it's related to deep sleep / doze feature. Try to restore factory settings and wipe clean data + cache of the phone and see if it will help. There's so many things that can cause this that we're not able to help any of you.

Thanks, I know, but that also didn't help me. Currently I am following this bug report at Google:
https://issuetracker.google.com/issues/109710373
It seems to be an issue witht he June Android Security Patch... a lot of Pixels are having the same problem.
I don't thinks it's the June 2018 update problem. If u look at the dates on this thread, the problem started after the oreo 8.0 update back in November 2017. Hopefully it'll be fixed in the android 9 update coming soon. I updated straight to 8.1 after unboxing so I don't know if this problem was around during nougat
Same here
I have the same error.

Phone frequently hangs or touch screen unresponsive

I'm experiencing hangs or touch screen unresponsive, I think its the touch that stops responding unless you lock and unlock the phone.
I have three weeks with the phone and started yesterday right after a Factory Reset. Before that, it never happenes.
Today its better but still happen
Attach an image with the touch's firmware version
Has it happened to you?

same thing happens to me from time to time, i have the phone for 8 days now, it started maybe 3 days ago, screen unresponsiveness happened maybe 4 times to this date
temp fix for me was downloading Google GO files and using it to delete cache, it works for now, no screen freeze up to this point
I think is not the same issue, I refer to touch issue thats come unresponsive some times until you lock and unlock screen. Now I'm testing android P which have another firmware for the touch panel. I will report later if dont presents the issue.
I installed the preview of the Android P developer and used it for two days and after a day of use I had the same problem, very disappointing, I went back to version 8.1, I do not understand why this happened, I never hit it, threw it, nor nothing. I was very carefully with it.
Has this issue been fixed yet?
We have a few of these phones in our family and one of them is doing this sporadically, several times in a row and then it's fine for days.
I can't see a pattern as to when it happens though.
Short Question : any of you using the Nova Launcher? Ive got same problem but using the Nova Launcher since years. Yesterday i did a clean Nova Launcher (stable) install and not taking my Backup file... And my Problem with hanging (Touch panel not recognized often my Touch) seems gone. Dont know why but after testing a whole of things im trying the standard Launcher and it works better.. So i did a clean install of Nova.

Hi guys, do you guys Enable or Disable "Tap to wake" function? If not, try enable that function, maybe that help.
Same problem in my Nokia 5.1 Plus. automatically touched at top of time side and battery indicated area. and i cant open notification bar.
I turned ''Tap to Wake'' on and my screen has worked perfectly since then. So i think this is definetely bug, not HW problen.
has anyone managed to solve this? its diving me nuts since the past few weeks and i dont know what to do with it. I would try to fresh install the OS but if that does not fix it, ill loose everything (game saves and such) but dont fix it.
i noticed sometimes the screen does some kind of refresh and then it starts working again. But mostly i have to lock and unlock to get it working again.

The only thing that worked for me was returning the phone untill the screen was replaced.
Everything else I tried (reset, reinstall, change settings, ...) led to the same problems after a while.
