Thank you! Guess I will stick with Android 9 Stable for the time being.
[OnePlus 6 Guides, News, & Discussion] Wilguens Joachin:
Wait so, latency is worst on OP4?
[OnePlus 6 Guides, News, & Discussion] AcmE85:
I noticed the same and came to the conclusion that the status bar icons for VoLTE and VoWIFI hve been mixed up in this beta.

When I disable wifi it shows VoWIFI instead of VoLTE, which makes no sense.

When enabling wifi it shows VoLTE instead.

Yes, for me it unfortunately is.

If you are back on stable Pie, could you please share all files found in:

System/vendor/etc/firmware/tp
[OnePlus 6 Guides, News, & Discussion] immarcel:
There's something seriously wrong with the touch registration on betas. I've had an issue on OB3 where my touch wouldn't register if i held my finger down at the left and right edges of the phone. Now I noticed that the same issue is there on OB4, but not on stable. I'm seriously considering rolling back just for this reason alone

EDIT: same applies for the bottom edge of the screen, making pill gesture navigation buggy
[OnePlus 6 Guides, News, & Discussion] AcmE85:
As I already asked, we need a stable Pie user with root who can provide the files under: System/vendor/etc/firmware/tp

This is the touchpanel driver. Currently I'm running Beta4 with the driver taken from Beta3.

While it is still buggy, it is better than the one which comes with Beta4.

The same was actually the case on the OP3/T. The Betas fixed touch latency at some point, but it took them 6 whole months to push this change to the stable builds.

OnePlus even brought the fix to the OP5 release before fixing it on the OP3/T!

Back then, copying over the beta driver and replacing it in the stable fixed the latency issues.

edit: so far each beta, starting with DP3, came with changed driver files (different checksum).

But the issue persisted since DP3.
[OnePlus 6 Guides, News, & Discussion] immarcel:
It's gonna take a long time for me to do a full backup, copy all the files to my PC, back to my phone and roll back to Pie but if I do before anyone else does I'll send them your way
[OnePlus 6 Guides, News, & Discussion] harigavara:
Can i move to stable pie from open beta 3 pie? If yes how?
[OnePlus 6 Guides, News, & Discussion] chintu1234:
Here. Drivers are from stable pie.
[OnePlus 6 Guides, News, & Discussion] Burt Squirtz:
All these people complaining about touch latency, no idea what you're talking about. never once have encountered this. Have dirty flashed all the way up release by release since 5.1.5 to OB4. also for some reason the word 'stable' makes the touch latency better in people's minds. i have seen absolutely ZERO difference in latency or smoothness in the stable or beta pie releases.

i do use Flash kernel though. never had a mousefart hint of latency.
[OnePlus 6 Guides, News, & Discussion] dante_nfs:
really great info. i believe it's not just the touch panel firmware, but it's within the kernel and framework too. the latency issue was there even from oreo! but it's just ok with stable pie.
[OnePlus 6 Guides, News, & Discussion] whizeguy:
Some people notice it, some don't.

Some people don't see delays in video games when the input lag is there, some do. There is also videos that show the delay, now.. On beta 4 it's less than beta 3 and a tiny bit more than stock. I also did some testing..

I too did dirty from 5.1.8 through the betas, to stable, to beta4.. Delay is there, lucky you that you don't see it.
[OnePlus 6 Guides, News, & Discussion] AcmE85:
XDA is giving me a 404 error, download doesn't work. I've tried on my OP6 with different browsers and on my desktop PC.

Could you maybe upload them to Google drive for example. Thank you!
[OnePlus 6 Guides, News, & Discussion] immarcel:
01 worked for me but 19 is giving me a 404 too

[OnePlus 6 Guides, News, & Discussion] AcmE85:
You're right.

I quickly compared the md5 checksum and the file is identical to the one in Open Beta 3.

I suspect the other file to also be identical.

So if it is actually better on stable Pie, there must be other changes causing it as [MENTION=5836840]dante_nfs[/MENTION] already said.

Rationally speaking, the latency isn't bad all the time on my device (and others), so there must be another underlying cause for this.

edit:

fw_synaptics_17819.img is actually different to the one in Beta 3 and 4.

I will do a quick test and come back...
[OnePlus 6 Guides, News, & Discussion] immarcel:
I tried overwriting the file, rebooted but nothing, touch latency and touch registration is still the same
[OnePlus 6 Guides, News, & Discussion] AcmE85:
Yes, you're right. Waiting for Beta 5... :crying:
[OnePlus 6 Guides, News, & Discussion] quimbexa:
All you guys experiencing latency should do a clean install. I don't get that with any of the Pie builds.
[OnePlus 6 Guides, News, & Discussion] whizeguy:
Clean dirty.. Same same.. Did clean just to try the difference. (format and did it all over.)

Some aren't sensitive to input lag some are. Beta 4 is fine overall.. Would think even gaming is fine aswell for those that are into that on a phone.. However, on beta 3 you can't play any game that needs aim..

For people that use their phone for Facebook, Instagram, browsing, texting, calling, sexting and what not won't be bothered with any delay..
[OnePlus 6 Guides, News, & Discussion] lAndroXl:
Im getting this "oneplus launcher" background in recent apps... Also the lockscreen isnt working properly... When using pattern unlock method the pattern gets overlapped with my notifications some times and the pattern is in the middle of the screen since open beta 2 (dont know if thats normal).

Maybe i should try a clean install too.
[OnePlus 6 Guides, News, & Discussion] immarcel:
the screenshot you posted is clearly broken, you should report it. as for the lockscreen bug, i get it a lot and reported it already
[OnePlus 6 Guides, News, & Discussion] lAndroXl:
Its the 4th beta now and the bug is there since beta 2...

Dont know why they didnt fixed it allready.

Thanks for your reply :)
[OnePlus 6 Guides, News, & Discussion] Toni Moon:
If it's the same has beta 3, beta 3 kernels (like smurfkernel, elementalX) will work on beta 4?
[OnePlus 6 Guides, News, & Discussion] AcmE85:
[MENTION=6143932]Funk Wizard[/MENTION]

I did some digging and noticed heavy log-spam on my device (multiple times per second!).

After some googling I found this:

https://github.com/flutter/flutter/issues/19810 (Error message after installing Android P Beta on OnePlus 6)

E/libc ( 7332): Access denied finding property "vendor.debug.egl.swapinterval"
W/RenderThread( 7332): type=1400 audit(0.0:400608): avc: denied { read } for name="u:object_r:vendor_default_prop:s0" dev="tmpfs" ino=16621 scontext=u:r:untrusted_app_27:s0:c512,c768 tcontext=u:object_r:vendor_default_prop:s0 tclass=file permissive=0

These are the exact same errors I see on a per second (or quicker) basis on my device with Matlog.

I'm not the only one btw: https://www.reddit.com/r/oneplus/comments/9jfa13/logcat_spam/

This quote sounds quite interesting thinking of the "

touch

"-latency issue:

Futher searching for "vendor.debug.egl.swapinterval" gave me this:

https://www.khronos.org/registry/EGL/sdk/docs/man/html/eglSwapInterval.xhtml

and an old XDA thread: https://xdaforums.com/android/software-hacking/mod-increase-frames-5-14-15-t3108786

So vendor.debug.egl.swapinterval has something to do with the displayed framerate.

This is probably far-fetched, but there could really be some connection between seeing this log-spam and experiencing random touch-latency issues.

Sometimes the touch-latency is just perfect, then suddenly there is a noticeable delay.

[MENTION=7385240]immarcel[/MENTION] [MENTION=5270700]whizeguy[/MENTION] [MENTION=5836840]dante_nfs[/MENTION]

I urge anybody with a rooted device to check for this kind of log-spam with Matlog, even if you don't notice any latency issues.

There must be a reason for the given errors. Keep in mind I'm not a dev, so when this is "normal", please be gentle^^
[OnePlus 6 Guides, News, & Discussion] quimbexa:
What is your opinion about this Beta? Coming from 9 Stable
[OnePlus 6 Guides, News, & Discussion] Burt Squirtz:
Lol me either. Never ever have experienced this. I use Flash kernel and no limits magisk module and my phone is blazing fast and super smooth on OB4.
[OnePlus 6 Guides, News, & Discussion] AcmE85:
Smoothness and speed have absolutely nothing to do with touch latency though.

My OP6 is also fast and smooth with ZERO issues if it wasn't for the touch latency spazing-out occasionally.

The fact that OnePlus is even working on this issue should be reason enough for you guys to believe that this issue exists.

We in this thread aren't the only users complaining. I've seen posts on Reddit and the OnePlus forums too.

We are not imagining things here.
[OnePlus 6 Guides, News, & Discussion] Burt Squirtz:
when I say speed I'm talking about touch latency. Never have encountered it in every single pie build. Ever. some people on here saying that it's just us 'not noticing it'. BS. It's not there.
[OnePlus 6 Guides, News, & Discussion] Jack_Sparrow_:
Can someone explain me how to "see" this touch latency???
[OnePlus 6 Guides, News, & Discussion] dante_nfs:
For God sake people, please read about the difference between lag, jitter, smoothness and latency

this are different! Latency is different from being smooth or having lag!
[OnePlus 6 Guides, News, & Discussion] AcmE85:
If you say you don't have it I believe you. I won't argue with you about your own device as I never had it in my hands. But you don't seem to believe users claiming they have this issue. Why though?

Why do we even have to argue about this. The beta thread exists to post issues. If you don't have the same issues, fine. Saying there is no issue is BS though.

Btw, we had the very same discussion on the OPO and OP3/T. Both had latency issues which got fixed eventually. And also back then we had users claiming there is no issue although OnePlus clearly acknowledged and addressed it.

edit: I really don't want to argue with you or be negative towards anybody.

Maybe you can help a little:

Please check my post for more info.

If you don't have latency issues, maybe you also don't have this kind of log-spam and we get a possible connection. Thanks

[OnePlus 6 Guides, News, & Discussion] vrda08:
Scroll something on your screen, and watch how much content on screen trying to catch your finger on screen.
[OnePlus 6 Guides, News, & Discussion] habylab:
Fairly sure you need external equipment to measure it.
[OnePlus 6 Guides, News, & Discussion] Jack_Sparrow_:
I didn’t understand what to do sorry...
[OnePlus 6 Guides, News, & Discussion] erad1:
try this and see if there's any significant delay

http://crostouchlatency.appspot.com/
[OnePlus 6 Guides, News, & Discussion] dante_nfs:
Open somewhere where you can scroll, like contacts, then put your finger on a name of contact then scroll up and down without putting your finger up, see how much the name of the contact you chosen is getting behind of your finger, this is latency. The perfect latency is that the name of the contact remain under your finger and not getting behind, or have a delay when you Change direction (in up and down, when you for example go down, the name goes up for a little moment and then changes direction.)

Try with different speed, while test, you will see sometimes even your finger is in bottom of the screen while the content you started drag from, is way up in the middle. You can use any app, like contact, Spotify library(try songs library), or any app that needs scrolling.

Another latency is flicking the screen (short burst drags) when you flick the screen, you will see a delay when the content starts to react to your flick and starts to scroll.

There is tap latency too, it shows itself if you saw and used a good device or rom, then you will notice tap performance too. But you can try with keyboards like swiftkey, type with them and see sometimes you can feel the keyboard is not that speedy in terms of the time when you tap the screen and then keyboard reacts to that touch(it's more difficult to see since you need to have a trained eyes and muscle and used a good device before to see tap latency), for example there is a clear difference between beta 3 and official pie in typing performance

The tap performance and burst drags are more difficult to measure but scroll latency is more easier to measure. And most of the time when a device have a bad scrolling latency it does have a bad latency in another areas too.

All of this package! With being smooth and lag free, and app opening speed, and in apps performances(third party apps) make the user experience of a device in terms of performance but many times even people forget about that latency is the first thing in user experience since touch is the first thing we do with the device.

if i were you i wouldn't be that interested in betas, much better feeling and experience with official pie.
[OnePlus 6 Guides, News, & Discussion] fireguy0306:
Good description of these. I seemed to have lucked out as the latency seems very minimal.
[OnePlus 6 Guides, News, & Discussion] BossNexusS:
Tried it on my phone too and my finger only lags behind the name by a couple millimeters.. Not as far as you are saying where the name is in the middle of the screen while your finger is at the bottom. It's definelty not that bad for me. I even went super fast and it still never goes farther than a couple mm.

You can only do that with a magisk module as of now

I did the same test on my pixel xl.. And the names are still off my fingers by a few millimeters.. I don't seem to have any latency issue.. Maybe the issue is only with certain units.

Fullscreen Apps

Do the Google apps (Chrome, Gmail, etc) show up in the Force Fullscreen Compatibility apps list?

They don't in the stable release. I flashed back to DP3 from the stable OTA to maintain the ability to have those apps run under the notch.

Wondering before i take the leap again.

Is it worth to update from Stable 9.0? Thanks
[OnePlus 6 Guides, News, & Discussion] MultiCulti:
sry friends, but i have to say this now!

it's really getting annoying, this **** posts about latency! every page you get the same 2 or 3 people complaining about this! (not just like a bug report)

please stop people driving crazy about this, who not even recognize or take care about this latency ...

ok, OP said they will improve this, so you got what you want!

There are devices out in the world with ~80ms up to ~300ms and more! And no "usual" User will complain about this!

There is even difference with latency with different screen protectors!

And as someone said, games like Pubg isnt playable, thats bull**** ... sry ... i play pubg since Oreo on my OP6 and there is no noticable difference!

So, OP said they will work on it, thats fine, but please stop driving others crazy about this!

Thx!

[OnePlus 6 Guides, News, & Discussion] MultiCulti:
ok, maybe i missed it on beta 2 ... but i recognized it the first time in dp3 :silly:
[OnePlus 6 Guides, News, & Discussion] AcmE85:
It is hard for me keeping my cool reading comments like this. What exactly is your problem with users wanting this fixed?

Nobody wants anybody to become crazy about this, this is an actual issue which seems to only happen on some devices.

As words don't really help here:

https://drive.google.com/open?id=1ZXPQPZWELJMCHQjIy92VdRN4JsnQh-zU

(this is 4k60, if watching online it is played back at 30 fps. If you still don't see the issue, download the video please)

As you can see my finger is going >1cm before the display actually responds accordingly.

And to say it one more time,

Beta 4 runs GREAT on my device. Performance is great, smoothness is great, even touch latency is great

except when it is not

as seen in my video.

If I had to put a number on it, I would say that 60-70% of the time latency is great. Then it suddenly starts behaving like on my video.

It happens regardless of app. I had this happen in relay for reddit, Google+, Instagram, statusbar pulldown, settings app, Chrome, Naked Browser, Google Keboard (while typing), WhatsApp... you name it...

Most of the time but not always it is fixed by going to the homescreen and back into the app. I did a clean flash already, surely won't do another one which won't help anyway.

There must be an underlying issue to this, and I already made a lenghty post about a possible reason asking for rooted users to check if they also have any log-spam. No feedback so far, but you could be the first to help in this matter.

https://xdaforums.com/showpost.php?p=77755213&postcount=1649

I surely won't stop addressing this issue just because you or anyone else feel annoyed about it. And this isn't meant negatively or offensive towards you or anybody else, I just need this fixed, period.

And yes, I also noticed funky behavior on the VoLTE and VoWIFI statusbar icons.

Currently on WIFI it shows VoLTE, even though it displays active VoWIFI in the dialer UI when calling somebody.

Disabling WIFI then shows VoWIFI while it should be VoLTE.

Enabling and disabling flightmode then gives me the VoLTE icon.
[OnePlus 6 Guides, News, & Discussion] RagingHarry:
Guess so ;)
[OnePlus 6 Guides, News, & Discussion] broomer68:
If the 1cm lag is horrible, then android is horrible, as I do not recall any different behaviour on any previous device. And I do always enable the touch feedback in the developer options.

I have always seen the touchpoint while swiping, on my HTC Desire S, asus zenphone2, cat b5, nexus7, op3t, nvidia shield k1, and now with the 6, I am not worried about this.

And it happened with stock and custom firmware, like cyanogenmod, aosp, lineage.

So please stop fitting if you experience 1cm lag, as this is normal behaviour.

If your touchpoint is half your screen off, you have a problem, but that can also be in the app you are using.

Also some apps do scroll like 4 or 6 lines at a time, while others do single line, that is a problem, but will possibly have to be resolved by the app, as it is a sign that the app does not leave enough processor time for the screen. Remember Android does not do multi tasking by itself, but is even more cludged as Windows 3.1 was.

[OnePlus 6 Guides, News, & Discussion] AcmE85:
And another one... sigh

What exactly is so hard to understand when I say the latency is good 60-70% of the time and what my video shows is happening 30-40% of the time regardless of the app

(once this happens, the latency is worse than on any other Android phone I have previously used).

You surely don't help with posts like this. Did you at least try checking the mentioned log-spam (if rooted of course)?

Im posting these findings to help resolve the issue, your response isn't much of a help though.

[OnePlus 6 Guides, News, & Discussion] dante_nfs:
Easy mate, many of this posts are completely useful and informative, and they are not so many! In fact if you see, they are less than other issues like recent menu! Or how to flash! How to dirty flash! How to get twrp work! And more like this stuff that is answered multiple times and can be resolved by search. Did anyone complained about this?! No! We are here to help and complain. It's like having a car which the suspension makes noise when you ride it, someone gets used to it and when you ask what is this noise in your car? He says what noise?! Because he got used to it and when you show the problem to him, then he realizes that there is a problem which shouldn't be there(many of us experienced something like this). Does it make the car unusable? No, does it bother? Yes!. The thing is many people don't know what to demand and what's their rights to get from a company or government until you show them, giving them the info, the knowledge, to demand something,to ask for their rights, to ask for details.

Android in it's core does have a performance problem, I'm not afraid to say that maybe op6 is my last android device, because you see much better attention to this details like latency in other platforms. Like 120 hz touch sample rate.if I'm hijacking the thread, I apologize. Feel free to delete.
