How to? Where?
I found another bug. I wrote about this once but it happened again! My phone is no more recording 1080p in 60fps! Before i have fixed this by factory reset but i dont want to dactory reset my device every few days. I dobt know what is causing this bug. It just stops to record in 60fps. Its stuck on 30fps

It's among your apps. It's called HiCare. You can contact them from there.

I found another bug. In Google pay app our camera doesn't work with bar codes. The app can recognise bar code. It must be hardware/drivers problem.

I am also facing the same issue. The home screen turns totally black after some gaming or sometimes after some apps. Don't know what to do or how to solve the problem. Also can not open the service menu by *#*#636#*#* code, it does not work. When I put the code, just nothing happens, the dial pad remains same. What about your device?
Waiting for next update, hope they fix this graphics issues ASAP.

Actually what does this service code do, sry i have no idea. But i tried this code i am not getting anything... And regarding graphic issue, i could able to fix only after restarting... Also sometimes i tried fixing by quiting the game and wait sometimes and then use homescreen menus. But the latter is not working all times...

I'm pretty sure this bug is Stock Launcher specific - I've had it using the Stock launcher, never using Apex.

The code you used is incorrect.
Correct code is *#*#4636#*#*

Sorry that was typing mistake. I enter the code *#*#4636#*#* but nothing happens. Any suggestions? Actually no codes work on my device. I am really worried about that.
This is weird, I have no clue what could cause this. I am not so experienced on this phone as well.

Recorded video and YouTube playback errors

Noticed today that when I record a video on my Honor 8 I can not play it back. It's just a black screen with audio. Also, the YouTube app just "loads" - good 4G LTE signal or over WiFi. Might be separate issues. Cleared the cache and uninstalled the YouTube updates.
Anyone else seeing this or know of a fix?

if you have installed magisk uninstall and it should work i had the same issue and it went away as soon as i uninstalled magisk with the provided zip on the thread after 21 day and couple of hours of troubleshooting
I don't have that installed.

But you might have another app that messes with the video driver.
Unless anyone pinpoints the exact cause I suggest you backup with Huawei Backup to SD or PC, factory reset, setup Google account and nothing more. THEN test to see if it behaves the same.
If it does, then you might have a malfunctioning unit.
If it doesn´t then it´s either an app or a file messing with your ROM. Try to restore your backup one-by-one app until you see the problem appearing so that you can identify the app.

How about xposed?
Hi There, we recommend you back up the device and perform a "master reset" to see if that fixes the issue. To perform a master reset, you will go into your menu and click settings, then go to Back Up & Reset. Follow the prompts on the screen to back up and factory reset, then continue by following the steps to restart and activate the device (note: you will need to have your Google email/password present at startup).
If you still can't get playback on your videos to work properly, you should call in to our knowledgeable Honor customer service center at +1-844-524-6667 and they can further diagnose the situation you are having with video recording and playback. Thanks for your question! (NS)
Video playback seems to be a general weakness on the phone. I have experienced occasional glitches as well as battery drainage. It could be that the hardware (imaging processor) is weak.
Do a factory reset and see if it works
I'd actually like to raise awareness about this issue, my device works great other than this video issue arising and is progressively getting more annoying every time it happens.
There was this previous thread where, someone else had this problem and someone said that it was a "Known Bug", but I'm not sure where the source for that information is. Thread HERE.
I've done two factory resets since I got the phone in hopes that the problem clears up but it still happens from time to time, and the only way to fix it is to reboot the phone.
A summary of the issue is this:
- Youtube videos only load, but don't play. If you have youtube red, the video plays once you leave the app and audio only plays in the background, and when you return to the youtube app the video continues to play, audio only, with a black screen.
- Playing recorded videos from the video app, or any video app for that matter (Built in Video app, MX Player), videos only show a black screen, and plays audio only.
- Playing videos in Chrome, or anything that uses the android WebView (Such as Reddit while looking at GfyCat''s), doesn't load or shows a black screen
- The only way to get it all working again is to Reboot the device. However, in some rare cases, it magically starts working again.
I did speak to a live support agent on the honor website (David B) about the problem about a week ago in order to try to raise awareness of this issue, in hopes that someone takes notice and finds a workaround or fix for the problem.
I know for a fact that this issue isn't caused by Root, Xposed or anything related to unlocking the bootloader as the issue happened with a fresh restore, and an unmodified device a few days into owning my honor 8.
In conclusion, we need to see and know how many total are having this problem, and how many people haven't had this issue at all, just to ensure that those having the problem (Like me) don't have a defective unit. If only a small percentage of us are experiencing this issue then there is a possibility that those who have this issue like me have a defective device and would need to take action quickly to somehow obtain a new device.
P.S: I've been trying to figure out what triggers this issue to happen and what 'Magically' fixes it while the device is on, without rebooting, ever since I got my device. I'll report back if I ever come across something significant
Update Sept22: I can confirm that there is some issue happening with the hardware decoder as in MX Player video doesn't play when HW Decode is selected but works when SW Decode is selected. Still trying to figure out how to get it working again from its broken state without having to reboot the phone
It seems that there is a software issue which makes the phone unable to use HW decoders correctly
its a reported problem with honor 8, many users are facing the same issue, hope honor fixes it soon with a software patch.
It released an update for both US and EU model, now it's time to wait and see

When streaming a video my fault is. It plays a bit the video pauses but audio continues as normal. This can be fixed by rewinding or fastforwarding a little but same happens again ever so often 3 times per half hour playback

Is it possible that you have YouTube with resolution optimization on Boost+? Because in my case, for instance, if I set the resolution optimization for Samsung Internet Browser (Beta), it becomes unable to go full screen with its built-in video player.

I Update The youtube to the last update
Then the problem come again ?
So I remove it until we get solution for silly problem.
still problem not solve

[Fix] multi touch/ghost touch issue

Those who don't know there are some people having ghost touch issues on POCO f1 and one guy able to capture it on the video. I personally didn't had the issue but after trying I was able to recreate the issue on my device. soon after I found the cause and able to fix the issue. this may or may not work on your device but absolutely worked for me. this seems to be a software bug. and no-one needs to panic. hopefully it will be fixed in next update.
how to recreate the issue?
Steps
1. download a multi touch tester app I used this
2. first do some testing yourself see if you can spot the issue
3. now do 3 finger swipe down (phone will take screenshot)
4. now randomly touch your screen with 1 or 2 fingers you'll notice 1 or 2 ghost touches.
How to fix Fix it?
Steps
1. go to settings>additional settings>button and gesture shortcuts>take a screenshot
2. and set it to none.
3. reboot
that's it!
the issue should be fixed
please let me know whether this worked for you or not
Yes.
As you mentioned issue was there.
But fixed with those steps.

Good stuff. I was skeptical at first since I knew something was off sometimes. Thanks for confirming it. Should be fixed if they took notice of this bug.
Thanks! The issue is 100% reproducible with the app. By turning off 3 finger screenshot shortcut, the issue goes away.
Guys, please file a bug, so this can be fixed and we can go back to using this feature.
1.Yes, that issue is due to the screenshot feature, but shouldn't the phone be able to distinguish between 3 finger touch and more than 3? Either take screenshot on four finger swipe or register it.
2.Can you please confirm if there is accuracy problem in PUBG aiming when you use multitouch? Like the multitouch bugs in Pixel and Zenfone Max Pro but quite subtle, the thing about the other devices are, they look and have been acknowledged by the respective companies regarding the issue but in our case, Xiaomi or Poco is making no announcement or anything.
https://www.youtube.com/watch?v=e5K2N6McC_s
The issue comes up after taking a 3 finger screenshot, but disabling may not be the only solution as this feature is quite useful also
What I have noticed is that after taking screenshot ghost touch is there till we use 1,2 or 3 fingers. Once we use 4, 5 or higher fingers the issue goes away.
Isn't it better to just touch screen with 4 fingers after taking a screenshot which somehow resets the ghost touch issue.
Have tried this solution with multi touch tester app
Mine is just fine even when 3 finger swipe screenshot is switched on
I can confirm that ghost touch issue still persist even when disabling three finger screenshot.
Mostly visible in pubg.
Great, fix worked
I didn't relize the issue but nice posting
Stop it! This is not an issue. It happens on mostly every phone that supports gestures. Test it on OnePlus 6 and you will get the same result.

Exactly! There is no need to prove this issue because Google itself confirms that they have done a mistake by releasing it in Oreo and they have also promised to give a fix in later Pie updates. And people who wants proofs can look up in the internet about the "Multi touch Oreo Bug" problem and how it effects user experience rather than spamming here to make a point.

Dude, google fixed the issue in the May or June patch and all other OEM's had to merge their builds to fix it. The problem is not there in MiA1 or MiA2.
Here is the bug:

Thanks
Maybe the original solution for 8.1 and P devices will work for this? It will either cause a bootloop, do nothing, or fix it... worth trying! Obviously an unlocked bootloader is needed for this (Magisk).

Updated to 1.8.10 yesterday and tried using Lens and Assistant this morning but both seem broken. Lens says "thanks for updating, we will be available soon" or something like that. Assistant freezes the phone and won't open at all.
Anyone else have this problem?
Agreed that fps is faster but haven't noticed the other two.

A double tap to turn off the screen works but on the lock screen. You will wake up with a double throttle to wake up the screen and extinguish it with a double thump.
I sorry for my English, I use Google Translate.
For custom launchers, try to clean cache files. I had faced some issues before cleaned caching
No issues after that, even in the duration of battery life
