Huawei Mate 20 Screen Recorder Issue - Huawei Mate 20 Questions & Answers

Hi everyone! I have a Huawei Mate 20 and I've been having issues with the screen recorder. Whenever I use the app, it only shows a black screen when I view what I've captured in the Gallery. Permission to draw over other apps is enabled and so are the other permissions requested. I've done a factory reset as recommended by Huawei's support team, but the problem persists. I believe it has an issue with facebook messenger as they both draw over other apps. I think I must also mention that sometimes, the recorded screen is black, but it shows the chatheads. Help, anyone?

Same issue with my Mate 20X. Any solutions plz???

This is what Huawei's Tech Support recommended me the second time I called. As much as possible I don't want to do that because this seems to be a software issue only.

Update: I tried running the screen recorder with messenger's permission to draw over tmother apps turned off. I restarted the phone with the mentioned setting and poof! Same thing.

It WORKS!!! Thanks @PhoneTechShop!
Yes, it was the stupid messenger and I have disabled the permission to draw over other apps. Now all is well. Really an annoying app messenger is! Hate the way it works!!

[Q] Camera crashes

Heya!
Anyone having some camera issues since the 4.4 Update?
Mine crashes and/or freezes randomly when taking photos with the software and hardware buttons. Sometimes the whole phone freezes and won't respond on any touch input. Sometimes lock and unlock it again helps but most times I have to wait a few seconds or use the "OFF"-Buttons.
Any fix for this?

Do a factory reset. I had the exact same issue when I upgraded and I had to do this a few times to get everything working.

Gosh, that sucks :/ Is it at least good to make a backup with the Sony app and then restore it or will this end up with the same error again?

You can try but I usually recommend just starting fresh since it could cause some errors.

if u want better chance not to see these kindda issue u must repair ur firmware by PCC.
factory reset means wiping firmware
but repair by PCC means install fresh firmware
:good:
I've got the same issue. It's actually worst when using SnapChat. It just freezes sometimes. I did a factory reset from the phone and this solved the issues for a day, but now it's back. I'm gonna do a full reset from the computer now and see if this solves it.
I have the same problem with the camera!! Anyone fixed this problem without factory reset?

And it's back. Camera often freezes the whole phone. When I listen to music, and starts snapchat and change from back to front camera, the whole phone freeze and the music stops for almost ten seconds.
Same here, 14.3.A.0.681. Did anyone found a fix?
The camera app opens and works, but at the moment to focus it just stuck on focusing and the photo is never taken.
I experience the same issue. Often, I have to wait for the camera to open, and SnapChat is unusable now. Don't really feel like resetting if people here are reporting that it doesn't fix the issues.
Same issue here. But on 785 (4.4, latest update, german TFT, unlocked BL and root). Camera hangs on every occassion, doesn't make a difference which capture method I use. Tried emptying cache and data for the camera app but that didn't solve anything. I don't want to reinstall my phone because it's a pain in the ass. Problem does not occur with the front camera.
I did find a fix!!!:
Just clear data&cache of the camera app and snapchat (just need to log in again). Now everything works smooth and quick again.
@madlive: weird, for me clearing data&cache fixed all my problems. Maybe try it again?

Having just sold my Z1 (after having .757 installed) and now using a 'spare' Z1 Compact until my Z2 arrives, I wasn't that surprised to notice that the Z1 Compact has exactly the same problems as the Z1.
Wiping, resetting, clearing the cache - all pointless in the long run. Any fix is coincidental. It's a bug that hasn't been completely fixed with .757. The mere fact I've had the same problems on both handsets shows it's the firmware.
If you unlock the phone and start up the camera via the icon, chances are it will work fine.
If you activate the camera from standby, it may fail (the freezing problem, or 'camera not available' error).
What .757 seems to have fixed is the issue where the phone starts to get red hot and then you get the warning that it's too hot to use the camera. I've been taking a lot of photos this last weekend and never had that happen, so at least Sony fixed one thing. I suspect that was down to a series of problems with the media server and creating thumbnails etc, all of which were fixed.
When you have the freezing problem, was the phone locked? In other words; was it locked, but you started the camera via the camera key or dragging up the camera icon? When you tapped power to turn off/on, did you then have to unlock again? If you subsequently unlock - does the camera work fine now?
My hunch is that this is where the problem lies. I've got pattern unlock and now have it set to not lock for 30 minutes. So if I'm taking photos, I unlock the phone and - touch wood - I have no camera issues for that time.
If the phone has locked itself later on, and I don't unlock first, I expect the camera to fail. Yet it doesn't always - but once is still too much. I missed a potentially awesome photo of my two year old son because of this - and it's bloody frustrating. Especially as there's no idea on when we might get another update.
Another problem I noticed on the first KitKat release was the on-screen keyboard appearing over the camera one time. I'd been using the keyboard in another app before firing up the camera using the button, so the camera fault must be down to how it sets itself up when launched - and what you were doing just before (unlock screen, another app) influences the likelihood of it crashing.
In any case, it's a pain.
But on the plus side, the quality of the photos I got over the weekend - mostly in manual landscape mode - are stunning. The phone is capturing a level of detail that is exceptional now. And auto mode is now generally pretty good too, suggesting it doesn't just bump up the ISO all the time.
Same bug here!

I'm having the same problem here. Does Sony is aware of this bug?
Does anyone know of a link where we can complain about it to the manufacturer?
I thought that something was wrong/broken with my phone, but then, after seeing your posts, it isn't... So no factory reset... Just wait for an update? even 3rd party apps seem to crash, expecially the google camera... Wth
I'm getting the same problem since the stock 4.4.2 update, battery life doesn't seem as good anymore either, but i'm always near a charger so the new Camera bugs are the most annoying.
You can't exactly "catch a moment" by whipping your camera out anymore, most of the time I'm waiting about 5-10 secs for the picture to appear ready to take a pic, especially noticeable on Snapchat or when switching from front-face to rear.
I woudn't mind but being on Stock Firmware I'm always waiting longer for Android updates, supposedly because of the extra rigorous testing etc!
bump !
it appears accessing camera from different locations (lockscreen shortcuts ...) confuses the mecanism, this added to some flashlight app and you're good to have the reboot-proof camera FC problem... pffff
Possible Fix!
*** possible fix! ***
I read this on another forum and for about 5 days now my camera has been behaving completely normal across all apps!
Little warning - for me this logged me out of some apps, and caused me to have to put some widgets back on - it almost behaved like clearing the cache when you're rooted, no data lost just a some apps liked twitter etc were acting like they were installed for the first time...
The method is to boot into safe mode once, then just power the phone off and boot as normal:
Hold down your power button
In the menu hold down the "Power Off" option and say OK to safe mode
Once you're in safe mode, turn the phone off
Turn the phone on again, it will boot as normal
Camera just now behave as normal!
Not only has it worked for me so far, but my whole phone seems a bit faster.
Good luck!
Yes have faced that issue with camera, just like my friend warned me :/ freezing, when clicking
Factory reset didn't do much good

Cerberus and Dropbox issues

Hi all,
I bought a ZF2 two weeks ago. So far I like it, solved some issues I had in the first days, but I still didn't find how to solve issues I'm having with these two apps.
1-I used Cerberus for years on my old devices and worked perfectly, it takes a picture using the front camera when someone tries to unlock my phone with the wrong PIN/Pattern. On ZF2 it shows enabled but simply doesn't work.
2-I also use Dropbox with the Camera Upload function enabled. So when I take pictures it automatically sends to my Dropbox account. On ZF2 it only works if I open the Dropbox app, which shouldn't be needed.
For both cases I tried enabling them on Autostart Manager, enabled all apps on Autostart Manager and even disabled Autostart Manager completely to avoid it blocking something. But none of them solved.
Does anyone have any idea of what to do?
Thanks
I have Cerberus too and the camera works, but the photos are all black, I think that it's because the Cerberus take a photo before the camera is ready.

That's weird. I even tried a Factory Reset and installing everything again, Cerberus is still not working. It doesn't even send the mail, not even a black picture.

camera became super slow

Hello guys,
I'm writing here because I've been running some frustrating problems with the htc camera application on my M8.
I run stock firmware, stock rom. never did any kind of flashing-modding or whatsoever, although I am not completely sure since it is a second hand phone. When i got it, it came on kitkat. I then upgraded directly to marshmallow.
Here are my actual software information: Android 6.0 / Software number: 6.16.708.1 / Kernel Version: 3.4.0 [email protected] #1 SMP PREEMPT. Build number: 6.16.708.1 CL683910 release-keys.
I used the phone for one month without a problem. Then, for roughly two weeks my phone run minor random crashes with a very weird soft reset of certain application setting after the reboot. I.E: I had to log back again on all my app which required log in: spotify, wechat, even whastapp once, etc. Every time the home screen would show me the "how-to-use" tips as if it was the very first time I run the phone.
The camera became unusable: once opened, every button on screen was unusable. It didn't take photo, it didn't go to settings. nothing of nothing. It couldn't even show the bottom buttons for returning back to the home screen or managing the multi task. The whole interface seemed to be completely unresponsive.
Two days ago, I decided to factory reset through the recovery and reinstall everything.
Everything seemed fine.... but the camera.
It takes litteraly ages (7s more) to save photos. The interface is super laggy, I have to wait sensible seconds to go to settings or switch the camera mode. It is not as bad as it was before the reset, but it still unusable.
I have to mention that I have an sd card formatted as internal storage. However, since the problem persists, I formatted as portable and eventually I removed it completely. Despite this, the camera still does not work properly.
I tried to wipe the cache of the phone from the recovery. Nothing changed.
I also tried to run the phone in safe mode to see whether it was due to some application conflict. Problem still persists.
I am so frustrated, I really want my camera to work back again. I mean, I need it because I love taking picture with this phone ( I often go for photo shooting at night) and the htc camera application gives you a great Manual Mode which I cannot find in other 3d party applications.
Do you have any idea of what it might be?
Many thanks for having spent time reading this post.
I hope you can give some good feedback on this.
Cheers!
I have ran into the same problem. I even did a fresh install of viper rom. And still very slow.
This started happening less than a week ago.
Good afternoon,
The same problem occured to me last week.
This problem started after I restored apps from titanium backup.
I can point our how.
But.. After fresh wipe, all caches cleared. Camera seems to work fast again, no lag.
So check your phone space.. Free ram available.. And your use of titanium backup.
That helped me.
Let me know if this does something.
Regards,
WyCkson
I have the same problem it just started yesterday.
at the moment im using a another application to use the camera.
i want the stock camera working.
i have enough space and enough Ram.
why is it that the camera is so laggy.

OK a fresh install of viper and camera works fine, after updating from the play store the camera is slow. I don't think this is a titanium backup issue, I think it's a new update for something on the device that's interfering with the camera
Fresh install again, removed Titanium Backup. Downloaded selected system Google apps and all HTC apps except for sense home. Camera worked fine. Restarted for the lock screen update and now the camera lags. Trying to figure out which app is doing it.

After some 'auto updates', my camera started lagging huge ammount ~ 6 secs. plus other stuff. . .
Sounds like the same problem. Please post if you find out what's causing it.
same here
I just noticed crazy camera lag this morning (seemed to be working fine just yesterday). The Camera app was updated 6/23, so I assume its that. Can't find any other HTC apps that have recently updated; and no recent changes to the phone (Titanium restores or anything like that). Been on the same build of S.ROM for over a month, with no previous issues.
same here! ...
Hey guys I found your page during my research, since last night I cannot use my camera properly as you said huge lags occur and until that moment I cannot find a proper solution. But at least I found! The source of our problem is HTC SPEAK app. When I uninstall the app's updates camera became more stabyl and my phone's getting warm issues solved!
Good luck.
Found Solution(s)
For me, its HTC Speak app. If I uninstall updates for this App, Camera is back to normal.
But there is workaround even when recent update for this App is installed.
Turn On Camera App, go to Settings-Camera Options-Voice Capture. Turn it ON, download language pack when asked and than use Speak App for Camera or turn it off (as I did). Camera is working like it should either way

Thanks, this solved my problem with the camera lag.
The same thing effects the 'Motion Launch Gestures' in Settings (Display & gestures). For some reason, it also uses language pack, same as camera app.

Are you trying to uninstall the Speak updates, or the Camera app workaround in Post #12?
If you are trying to uninstall updates, you can find the app in phone settings under Settings>Apps>Speak. But for me, the option to uninstall updates is grayed out, and cannot be selected.
For the workaround: when you select "Voice Capture" in Camera app Settings, it will ask you to update the language pack. Select to update it. Then, once that is updated, the camera will work fine. You can leave "Voice Capture" on, or turn it off in Camera app settings; either way, the camera should work fine now.
The option to uninstall updates was also greyed out for me, but you can select the menu icon in the top right corner of the Speak app settings to make that option available. I did this and yes it did fix the laggy camera issue but did not fix the non-functioning gesture control. The workaround that 3alfa3 provided fixes both issues.
Thank you to everyone who has helped resolve this issue as HTC support were as much use as (insert your own witty line...)

I can confirm it worked for me too.
Enabled voice capture after couple of lags, and just hit the download button. Couple of seconds later baaam! Solved.
But Its really strange reason to lag. Curious about how you figured it out tough..
Many thanks.
Just uninstall HTC Speak ... i test this on 3 devices ...
Same problem here.
Turn On Camera App, go to Settings-Camera Options-Voice Capture. Turn it ON, download language pack when asked <--- did the trick for me as well.
When will HTC wake up and fix this?

Screen Flickering

Hi,
So I offer this phone to my wife this xmas and everything was going smooth until we found this issue:
https://www.youtube.com/watch?v=xYFdyDwuS_w
The bottom screen does this flickering when typing with Swiftkey keyboard on some apps. This one is Doggcatcher but it happens on other apps too.
If I swap to GBoard it does not happen. We're on Android Pie 9.0.
Has anyone found this issue?
Seems like a graphic bug in that specific keyboard.
Please, i need help.
Evaluate for yourself whether it is related to this topic.
Occasionally, graphical glitches appear on my Mi A2 lite, (4/64, Android Pie, December update, locked bootloader, no root, intact system).
In most cases, they flickering all over the screen, and in some other cases they are frozen, as is shown in attachment.
They are completely random and they appear through many applications that i use.
I can not determine the cause.
Does anyone else have a similar problem?
me... on chrome and all app that use webview... during call status bar is flickering... when switch to the camera in whatsapp with swipe to set status... and other
Something similar here, if Facebook Messenger chat head is overlaying YouTube it flickers a lot (only the actual video but the description and recommend are always working without flicker also no problems in fullscreen), less often it happens with Chrome and sometimes YouTube does it without Facebook Messenger even being open (Android Pie Dec. 5) [also it didn't happen for the first few weeks with 8.1 then Pie got released and worked well for some days then this started to happen]
I have that problem , the notification bar flickers a lot and when on video calls, it shows a black flickering rectangle at the bottom of the screen
Hi, I've got the same problem here. For me, the flickering appears when the keyboard is open, and get faster while typing, please does someone know how to fix that?

The problem with the flickering screen in some apps like Youtube, Chrome or Instagram can be fixed as follows:
Go to Developer Options and activate "disable hw overlays"
However, the setting must be set again after every Phone restart.

Isn't that bad long term?
"Without a hardware overlay every application that is displaying things on the screen will share video memory and will have to constantly check for collision and clipping to render a proper image, this can cost a lot of processing power. With a hardware overlay each application gets its own portion of video memory, getting rid of the need to check for collision and clipping."
