Black screen settings app - Huawei Mate 20 Pro Guides, News, & Discussion

Hello to everyone,
Unfortunately my super Mate 20 pro decided 2 days ago to make me a surprise! My settings app decided not to open anymore. Every time I click on it I see a black screen. Nothing to do even restarting or turning on with 10 seconds of the power button. I freed up some memory, cleared cache... absolutely no sign of life. Everything else works flawlessly. You are my last hope. I look forward to your kind and professional reply. A thousand thanks!
Ps. Sometimes the message appears "the app is not responding. Close or wait?"

Flash to custom ROM.

Different camera problem?

Hi,
I am trying to find a solution for a problem with the Xperia T camera, I tried looking through the forum but couldn't find what I had exactly.
When the camera app starts if you do nothing and just look around with it, it will just shut down suddenly, sometimes after only 5 - 10 seconds. The amount of time varies but is normally very quickly, and it is becoming very annoying with the app vanishing just as you are about to take a photo. There is no black screen, freezing, slow down during or after and no problem starting it straight back up.
It was on T_9.1.A.0.489 (Three) and I tried repairing it. The problem is still there after flashing 9.1.A.1.140 today.
Anyone have any ideas? Thanks.

How are you starting the camera app? via the camera button or via the app icon in the app drawer?

It happens after starting it from the lockscreen and from the camera button. I can't be sure about the app icon, I haven't really checked. It is my gf new phone, but I was using the camera recently when I needed to take some pictures and video at uni so I was the one who noticed it and she had pretty much not used the camera yet. She always gives anything that needs fixing to me, so that is why I am now looking.
I can try from the app icon later, don't have the phone with me just now.
Edit: Apparently it does not happen when launched from the icon, is this a feature then I take it?
I did actually wait and try it with my Xperia Z I got on Wednesday before posting here, in what was now a failed attempt at not looking stupid, and thought the Z was free of it but I have gone back and checked and it is happening but with a longer time before closing (Xperia T normally around 15 seconds although has been shorter, Xperia Z is around 30 seconds so I did not notice at first - and both are fine from the icon).
Is there any way to stop it, I would like to launch the camera conveniently without it timing out on me so fast (and the same for my gf who has an actual button like my last phone the Arc that did not do this).

App opening lag when clicking on notification

Anyone experience lag in opening an app when a notification comes through?
When I click on notification for some apps, it'll take anywhere between 3-10min to open. Only happens on some apps. Viber and smartthings are 2 that I have noticed this issue on.
I've noticed some slight lag in apps opening from their notification, but that's measured in seconds, not minutes.

I've noticed a lag of about 45 seconds once or twice. Usually a reboot will resolve it but it could be an errant app or especially if it's trying to retrieve something from the web before showing the window and you have no connection temporarily (poor programming practice) etc...

Only with Secure Folder and only after updating apps in that folder.
Hmm... Maybe an uninstall and reinstall of those apps.. Will try it out once I have a chance to backup.. Must be the way I use my phone.. As same issue was happening on previous phone I was on..
Exactly same failure here. But not minutes, just a lot of seconds. I can click on the notification and then wait, and wait, and wait, open other apps, navigate, and then, suddenly, the app of the notification opens. Very annoying. Lots of apps having this issue.
Reboot the movile solve the issue, but it returns few hours later.
I have never formatted the movile yet, and updated from nougat to oreo. If anyone give us a solution, I think I will format the mobile.
I see there is few people answering this thread, maybe few people having this issue...
never happens at all to me
I have never had this issue, all apps open quicly when clicking their notification
Same here. Stock, updated from Nougat to Oreo.
On my device only notifications from the Play Store cause lag.
It is not that often, therefore I keep calm
I am also having this exact same issue on my Note 9 with 8GB of ram, running Pie O.S. and it is driving me crazy! Someone PLEASE help us figure this one out!
I have wiped phone cache in recovery, even the cache for certain apps, rebooted the phone and in some cases even cleared app data and STILL have this problem.
Thanks.

Factory reset might solve all these.
Thanks for the suggestion, however I always save that option as an absolute last resort.
Hopefully someone has experienced this and has a solution short of a FDR.
Anyone?...
I encountered issues like that more than once. Narrowed it down to /data that causes the issue to happen, as OS reinstall without userdata wipe changed absolutely nothing. OS version doesn't matter. 5.1.1 and 6.0.1 behaved the same.
I've also found that when the said thing happens, you can probably notice another things happening, such as the prompt (when you open terminal emulator app) appears after seconds or sometimes even minutes.
Call recording apps start recording at least few seconds into the call, so short calls in some cases won't be registered at all.
Banking apps will notify the user about ie. incoming transfers with a slight delay.
It's like events - external and internal - get stuck somehow. They can also pile up if you, for example, start another instance in app - you click a button a few times and after some time you'll get those few instances starting instantaneously and simultaneously, just as if somebody lifted leg from a brake pedal. It doesn't have much sense - every single one should be delayed by approx. the same amount of time, but they clearly are not.
Anyway, I'd be very happy if we could figure out what causes that, because doing a complete wipe, even with help of Titanium Backup regarding the restore (did that once, worked perfectly), is not something I'm looking forward to.
I continue to have this issue on my note 9..and now on my note10 plus the issue has returned after over a month of use.. Sigh.. I've completely turned off battery optimisation but no luck..

Performance and app problems ? U.S. Version...

I am finding that my apps that send notifications, specifically that I send through LIghtflow, are either not notifying, or doing so 30 min. to an hour late.
I am also finding that installing as well as uninstalling apps are quite slow.
POwer saver is not on; battery optimization is not on for the offending apps; they are set to run in the background.
Anyone else experiencing this? Or any suggestions?
Regarding the slow downloads, I am finding the download finishes (according to the status bars, etc), but it then goes into a state of Install Pending. Can't find anything on that.
For anyone who cares, I have it resolved for the time being.
After 2 factory resets, I remembered back to the days i used to root my phones, and remembered that one strongly recommended task in that process was to delete cache.
So I did a final factory reset and deleted the cache also and all seems to be good.
When this crops up again I will try the cache delete w/o a factory reset and see how it goes.
Not getting much help here but I'll keep this thread upgraded.
It is again not working right. Lightroom is either not notifying or it's doing it 30 minutes late.
Play store downloads but then doesn't install for a period of time.
I'm beginning to think something is wrong with the phone.
This thing is driving me nuts. Following is what's going on, and have seen:
I've gone through 4 factory resets. All works find at first. Having decided that maybe there is an app interfering, I installed an app or two, tested, repeat...with delays between repeats. All seems fine.
But then late into the second day, w/o any installs, I goes haywire again. Symptoms are:
I use DGT GTD for my ToDo list. First thing I will notice is that when I add a new task, it will NOT show up in the widget list, and at the same time it stops notifications.
All apps stop sending notifications to Lightflow...or LIghtflow does not recognize the notifications. Not sure which is the case.
When add a new app on the Play Store, it downloads as quick as normal, but then it takes forever to install.​
I installed AVAST, and checked for viruses. Came back clean.
I suspect it could be a phone problem. My Mate 9 works fine right now, with all the same apps. But, when a factory reset results in it working (at least during the short time a tech would evaluate), the phone can't be exchanged.
If anyone has any thoughts. I'm all ears. I'll keep posting, hopefully, ultimately, with a resolution. Maybe it'll help someone.

phone randomly turning off

Hey all just checking to see if anyone has same issue, it is persisting beyond an update. I plug in for night and usually every morning screen is off. Takes me holding down power button for ten seconds for it to come back. Not sure if I'm rebooting phone and it was on or if it was off.
Same here. Got it 2 times. No idea!!!
Exactly same issue, happens every 3-4 days.
I have same problem. After last update, that hapoend 3 times already. I wonder why...
Guys you have to search before posting. Here is the topic i made a while back. Have had this issue since then and i notice it because i have the aod (always on display) and the screen disappears.
https://forum.xda-developers.com/ro...ly-to-hold-t3994037/post80721405#post80721405
Apps i suspect:
Blockada
Owntracks
Health mate
Spotify
Which of these are you guys using? Maybe we can deduce if its an app or some firmware issue.
From your list I'm using only Spotify. However I'm afraid that my phone was turning off even before I got this app. Will check anyway (already uninstalled it), and will let you know.
What I can say for sure is that my phone is switching off completely (not only display) as all my Bluetooth devices are disconnected straight away.
Hope we will find a solution for this issue!
it happened to me twice as well, having the phone for almost 2 months. It is a bit annoying and I dont understand why it happens. Among the list of these apps, I only have Spotify installed as well.
I dont have any apps from Your list. My phone turned off twice since last update, before that, for 1 month everything was ok. Now seems good aswell, we will see.
Seems like its none of the apps. My phone also completely disconnects from my devices and none of the buttons work (like double press volume button for camera). Have to hold the power button for a while and it starts up.
My Always on display is off
Random phone off was happening before the update and it's still happening after!
Also at times phone send to be so sluggish! 7gb+ram still available at that time.
North America 12gb/512gb.
All stock.

Ok, this issue together with the reported complaints of dust in camera lens has made me hold on the purchase of this phone.
Isn't there an official ROG II forum where all of you can complain so Asus can look into this issue maybe request dump files and resolve it once and for all?

Well my doesn't randomly turn off and I'm using blockada if that sheds any light...
Also, I don't use Spotify
I have deleted all the apps. Literally done a reset to the factory settings to see what happen and this morning phone turned off again... That's really annoying.
I have found relevant topic on Asus forum: https://zentalk.asus.com/en/discussion/12715/rog-phone-2-12-512-freezes-and-auto-restart-problem
Looks like they are not fully aware of the problem....
Is there any update for this case?
I'm experiencing random hangs as well after updated the firmware to the latest. It reads my power button and will shows the options to reboot but the UI is totally not responsive, have to hard reset it Everytime.
Since factory reset everything seems to be fine, however it's just few days since I have done it.
09/12/2019 - I can confirm that after factory reset everything works fine. If anything change I will let you guys know straight away.
02/01/2020 - Annnnnd it's back... After few weeks phone started switching off again and tbh the whole thing intensified. Yesterday phone went off 9 times. On top of that when it's off it drains battery like crazy - 5mins and 20% is gone. Bluetooth doesn't work properly as well. I'm aware that others don't have any problems with ROGII, however I'm afraid that due to personal experience I won't buy Asus phone again and won't recommend it to anyone.
Rog phone 2 turns off automatically
Same problem here happened twice in 2 days everytime phone is off i have to hard restart to switch on the phone
Does anybody got any solution for this problem
Yes I have faced a similar issue since I have updated to android 10 beta. This happened once. I left my phone for charging and the screen blacked out. I had to press the vol up+dwn and power to restore the functionality. Strange.

What version of beta you use?
It happened to me twice in three months. The smartphone got stuck/freeze in standby mode: no response from the physical buttons or touch. I use the official android 9 rom.
I managed to restart it with the power button and volume up/down pressed for 15 seconds.

No apps install in the list nd it randomly switch off my phone it's software issue
Mine started turning off after 1 minute of use. Couldn't stop it nor control it.
Managed to barely get the WhatsApp backup and then factory reset the device. So far things are ok. But setting up from scratch is a pain in the ass.
I suspect that I tried to enable twin apps on WeChat while being on Nova Launcher. That may have triggered something, But I'm not sure.

Random vibrating and getting kicked out of apps!!!

Hi all,
I'm at the end of my tether as my P20 Pro has started glitching incessently.
It's vibrating randomly (and regularly) and any time I try and go into an app it kicks me out within a second or two. I've not dropped my phone, it's not been in water and it's really starting to p*ss me off as I literally can't even send a text/WhatsApp without being booted out.
I've had the phone around 20 months and the cynic in me thinks Huawei may have deliberately bugged it to force me into buying a new phone. I've tried deleting unused apps, clearing cache, deleting old gallery videos etc but it hasn't made a single bit of difference.
I know there are a lot of posts on here about notification issues and random vibrating but this is definintely nothing to do with notifications. I've loved this phone since I got it but the past week or two have seriously p*ssed me off and I just want to smash the phone!
If anyone could help I'd be forever in your debt!!!:fingers-crossed:
Cheers

When it's vibrating is anything happening in the notification bar?? Mine started doing that last week and it was a call app I had installed. It could be you have to go through the notification settings for each app. Is there any particular application that you are noticing it on? Sorry for the questions. I hope you are OK x

Hi mate,
No nothing shows in notifications when it vibrates. It's actually a different type of vibration than you would get for a normal notification as well. It's a very rapid vibration that comes and goes. Initially it started kicking me out of my camera gallery and then started happening on other apps as well (Google search, Golf Clash, Snapchat etc). It's settled down the last couple of hours but I know it'll flare up randomly again at some point!:crying:
I also have problems with people trying to hear me on phone calls as well but assume that's probably a completely separate issue!
Cheers

Instead of smashing the phone I would suggest factory restore.

Have you ran the support app see if it's a hardware issue? I'd try and do a factory reset if that does not work because its difficult to diagnose. I hope you are staying safe x
