Screen not working? - Huawei Mate 9 Questions & Answers

It's sort of laggy, when I want to tap on an app to open it, for example, it takes a few taps or sometimes just doesn't work at all.
The problem doesn't seem to be only on one area of the screen though, the whole screen has the same problem.
Haven't installed any recent updates or anything, in case that could be a cause of the problem. I've tried restarting the phone a few times and also wiping the screen but it hasn't worked.
I've also tried using the optimise and clean up options in the Phone Manager, but they haven't improved anything...
The screen was working like normal just this morning, but then around late afternoon the problem started.
I haven't installed a custom ROM or any other major modifications like that, by the way. The phone is pretty much the same as it was since I bought it. EMUI v8.0 and Android Oreo.

Try a factory reset?

Screen time out not working

has anyone run across this issue when you set a specific time out, the screen dims after the specified time but does not lock, it stays on?
my phone was working just fine, stock not rooted, took the latest update and after that i've been having nothing but weird issues, the other day the notification area at the top was not working, i had to basically check every app, messages etc manually to see updates, had to factory reset the damn thing, now this screen issue, the phones is only 1 month old.
any input?
thanks
I'm having very weird issues with screen lock. I'm be on the phone and the device will randomly lock and not let me unlock it without restarting the phone.
The new update is when it all started. I don't want to do a factory reset, but it's looking like I might have to?

Display stops working, mostly, on second boot after installing non-stock.

I've got an odd problem with my p900. If I install any lollipop ASOP ROMs, the first time I reboot after initial install, the display mostly stops working. The first boot works fine, I go through the setup wizard, set everything up, and the tablet works and displays fine as long as I don't reboot.
Specifically, what will happen if I reboot is that the tablet will go through the normal boot, and get to the point when the wallpaper and status bar will come up, but no homescreen icons or anything. Then after a while, about 2-5 minutes, the display will go black except for the status bar. I can pull down the notifications drawer from the status bar, and it will display, as will the quick settings, but anything I tap to try to interact with will seemingly just do nothing. If I have 'show touches' on, then touches will display properly, anywhere on the screen, but they seem to do nothing. I've tried trebuchet, google now, and adwex, the home app doesn't seem to make a difference.
The problem first began in I want to say october, when I flashed a CM12 nightly update. I unfortunately no longer remember which nightly I was on nor which I flashed to. I of course immedately tried to flash back to the previous nightly when I discovered the problem, but it did no good. It took me a while to figure out the pattern to the problem after it first occurred, as I often don't reboot the device for a long while after a first install. I don't have a lot of spare time to devote to sitting down and just focusing on trying different things, so it wasn't until president's day weekend that I tried what I *thought* would fix it, ODINing back to stock and installing the latest CM12.1. Clearly that didn't work, or I wouldn't be posting.
I've tried the 20151104, 1029, 1006, and 0910 CM12.1s from http://forum.xda-developers.com/gal...nt/rom-cyanogenmod-12-lollipop-5-0-1-t2971945. I've also tried Civz lollipop, pacman, and resurection remix. Anything not stock based has the problem. I tried running stock, but I've been running CM since G1 days, and I just can't stand stock, even the stripped down and modded versions. It just doesn't work right, and I can't get used to it, even after forcing myself to use it for several days.
I've never encountered such a weird problem, and I can't seem to find anyone else having a similar problem. I have no idea how to troubleshoot this beyond what I've done already. I'm currently running thompatry's Cm12.1 20160212, having not rebooted after the initial install, and it's running mostly ok, but I live in dread of my battery dying, and of course I can't install any xposed modules like xprivacy or multiwindow, which is bothersome. I have the wifi only US model, v1awifi, and I'm currently running TWRP 3, tho I was on TWRP 2.8.something when the issues first started happening.
what's the last 3 characters of your bootloader version?

Have you tried changing kernel? I mean in the case of civz lollipop rom you do get an option of 2 different kernels try choosing the opposite to the one you had chosen before. Thank you, hope it helps.
I won a year ago 2 Note Pro, one works flawlessly while the other is slow af and it has the same issue that you speak about. If I stay on stock everything is good more or less (sometime little slow), but if I install Lineage or any other Custom Rom is too slow and has the same issue you speak.
I changed both batteries, but nothing to do. If anyone knows, text please.
Thank you!

Marshmallow problems with spontaneous launching of Google Now, taking over device.

My phone has been misbehaving since it upgraded the OS to Marshmallow. It was primarily occurring with the Google Now app and it would take over the phone and flash up and off the screen and whilst this was going on, the phone is busy vibrating, the screen became unresponsive and generally I couldn't do anything with it during these episodes. I stopped it sending to the screen and then it was the Google app that kept flashing up, starting with a round circle coming from the app drawer icon. It has got worse over the last few days to the point that it might take me ten minutes before I could get access to the caller to make a call and even trying to shut down the device was near impossible because the confirmation box never stayed on the screen long enough to answer the question and then it didn't come back. Yesterday, after many tries to restart, it finally restarted in safe mode. If it was related to an app that I downloaded, it should have stopped then but it didn't. When I was able to get into settings, I then went to apps and then disabled google app as this was the one starting up and flashing the screen non stop. I was then asked if I wanted to replace it with a factory version which I did but I also left it disabled. The problem has continued but not as ferociously with the screen becoming unresponsive at times while the buzzing from the vibrate still occurring. I have looked up various forums but haven't found any that have similar problems described. I checked the screen overlay settings and they are enabled and that seems to be the main problem with marshmallow. I'm looking for some advice but realise that this might be too basic for this forum?

When you updated to Nougat, what method did you use to update? Did you update via OTA? We're you rooted when you did it?
Have you tried booting to recovery and factory resetting and wiping cache then rebooting?

It was an update that appeared on my notifications and I thought it was a small bug fix update and didn't realize that it would replace the entire OS. I just allowed the update and then realized what had happened. I think it is Marshmallow that it updated to but originally the app drawer was paginated and accessed by side swipes whereas the system now is a long page of apps moved up and down. I don't know if it was rooted and I assume that that means it wasn't.
I was trying to avoid a factory reset but I did wipe the cache and rebooting. When google apps is disabled, the interruptions are less often and not for as long but it still went into a complete meltdown of a screen appearing and disappearing at such a rate that nothing can be done with it. It won't show a video because of the interruptions.

Unfortunately, I think you're gonna have to factory reset in stock recovery because there's obviously a conflict with something you already had on the device and it isn't playing nice with something that was in the update.

Thanks for taking the time to respond. I have resigned myself to that although it does not seem to be anything that I downloaded to the phone as it occurred in safe mode too. I was just hoping that there was a fix out there but obviously it is not a widespread occurrence.

It could have been something in system that got changed during the update but the data from before the change is still there and conflicting with whatever changes were made. Some kind of saved system data that can only be wiped by factory reset or reflashing.

I did a factory reset, lost a lot of photos that had started being saved on the phone and not the sdcard after the upgrade to Marshmallow. Have had to accept that but unfortunately the bizarre behavior did not stop and it continues on and off, sometimes so bad that I cannot dial a number on it and other times it happens but I can get in between the action and dial or send a text etc. I have gradually been stopping things like notifications from google apps and traffic reports from google maps (this may have had a good effect) and anything that might be doing constant checks. It seems to have quietened down over the last day or so and I even got to play a game on it but the next option is to send it away to an engineer. I just thought that I would let you know the outcome of the factory reset.

Why does my Google Pixel randomly reboot?

Hi. My device worked just perfect until 5 days ago. It slowly began to ignore some tasks like opening apps or doing calls.
2 days ago my google pixel with Android 8.0 started to ignore every input i made, like opening apps or trying to reboot. It behaving like this after taking some pictures with the rear cam. After some attepts in opening apps it started to reboot. But instead of a normal reboot it stuck in a booting screen (the one with the Google G and a gray animation bar underneath). It took a while and i waited until it seemed that the OS booted correctly. But after this my device started to reboot randomly after a few minutes. After a while i figured out, that i can hold the power button while the screen with the google G was up to reboot it normally. This worked so that the phone was at least half an hour or more working until it rebooted again out of nowhere.
So far i tried to get it in safe mode and delete some apps like whatts app etc. In safe mode i didnt notice any crashes so far.... but in normal one it does a lot so deleting apps wasnt helpful. Turning on flight mode was not helpful either.
What can I do? What could it be?

Same thing happens with my Pixel, sometimes the phone is just get stuck on some random screen then I have to press and hold it for 15 seconds to let it reboot again. Lately I have started to see another problem, when it reboots bunch of google apps and services stops working and gives hell lot of notifications. All this started to happen after Android Oreo update

I noticed problems with my ear speaker as well. And i cant make phone calls. The phone doent respond anymore when i try to.
Same problem after android 8.0 update
If you have installed the latest Google phone/dialer app, that is likely the problem, was for me.
Find the app in settings and uninstall,it will roll back to a previous version and hopefully fix your issues.

My pixel does the same thing, ever since I updated to 8.0, have you tried doing a factory reset? I haven't done it yet, I have been uninstalling apps for the last couple of days, when it is in safe mode it works good, but when it's not, it freezes and restarts. I'm going to try uninstalling the latest version on google dialer to see if it helps.
I just want to update everyone in case you are having a problem with the random reboots.
I uninstalled the phone update and it was still randomly rebooting so I backed up the stuff that I needed and just did a factory reset. I have been a full day on my phone without any problems. I did a factory reset twice, just in case, for some crazy reason, the phone still had a problem, I wiped it twice! I think you'll be good with only wiping once.
Anyways to sum it all up, I did a factory reset, restored all of my backed up data from my pixel, I had about 120 apps and the phone has not had a problem since. I hope it helps someone else.

Mate, please report if you're still getting the reboots. Mine disappear for two weeks after I do a factory reset and then come back. Same happens in Safe Mode. Bug report claims it's 'Sense Key : Hardware Error [current]' and Google rep says it's a hardware issue (Toshiba's memory or something). Buganiser thread is here.
wrong place sry
Had this on my pixel xl. I was on the 8.1 beta.
factory reset, rolled back to 8.0
8.1 ota official
haven't had a reboot in over a week now

Yea, the issue is back, has been for about 2 weeks. This phone is really starting to be a pain in the ass, I can't believe that it happens so often. Did you do a warranty fix?
That's a pity. Yes, I did. Got the device roughly two and a half weeks ago. Flashed 8.0 and then sideloaded 8.1 right away. Knock on wood, all good. But there's still a report every other day in Buganiser of a phone even on 8.1 doing this.
Got mine at release. November 16. Google won't replace it either. I have a one pixel brick
I have the same problem. However, it is not frequent enough on Android P beta. But as soon as I go back to the stable build, it starts to do the same thing. Did you guys have any luck resolving this or should I send it back to the vendor I bought it from. They won't replace the device in Pakistan but may be will fix it in some manner.

Laggy Pixel - almost impossible to make/receive phone calls

Hi all,
Pixel 1 after one of the latest updates turned into almost unusable piece of junk ;/
I do not know if this is OTA update issue or hardware fault, but phone must be restarted frequently, otherwise is almost impossible to make phone call - phone is laggy, screen doesn't respond properly, sometimes must hold power button for several seconds to force reboot, as it is not possible to reboot using the screen.
After reboot seems to work fine until someone is calling - when I answer, the caller cannot hear me and I must restart the phone again to make another try. Sometimes it work and I can talk over the phone, but mostly don't.
Phone never been rooted or anything, always updated with the latest OTA software.
I did factory reset - no change ;/
Is there anything I could try? I was thinking to try to go back to older software, but I'm not sure if this is software issue, as didn't found any other posts on this forum describing similar problems.
It is unusable anyway, so I will try anyhing.

Ive updated to latest ota on pixel 1 and had no problems so far. You could check the dialer app is set as default dialer and all permissions are granted and maybe clear the apps storage/cache, force stop it and re open it and see if that solves anything? Could also check background apps and running services in developing options to see if an app is banging out the memory causing it to lag?

if you already did factory reset then it must be a sign of motherboard is dying soon or bad nand chip. motherboard failing on pixel is very common but it happens to less than 1% of people. there are plent of threads on reddit/xda on this.
What's the status of your Pixel? Is the bootloader unlocked? Rooted? Did you have any such problems on the December udpate?
As mentioned - I did factory reset as I thought it may help cure the problems, but it didn't.
I have never unlocked bootloder and phone is not rooted. All standard here.
I have the latest update installed and same problems persist ;/
I'll try another factory reset today.
