Although i'm very grateful for the explanation and trying to believe it, some things don't match together.

First i have to say that also my not yet mentioned U11 does not suffer from this problem.

I also tried the honor 9 some months ago and that device had similar issues (but worse) on Android 7 and 8, no difference.

Saying that 8.1 might solve it - don't you think there is a way the manufacturers COULD do it themselves before?
[Sony Xperia XZ2 Guides, News, & Discussion] CaraMuuu:
You're totally right. The assumption here is that the error originated in AOSP but can be fixed by manufacturers as well, not only by Google.

Or maybe we are taking the wrong approach and it's exclusive to digitizers produced by certain manufacturer, like Synaptics, goodix, etc.

All in all, we can be 90% certain that it's a software thing. Potentially connected to some hardware choices from manufacturers, but almost definitely fixable by software, if they put the effort.
[Sony Xperia XZ2 Guides, News, & Discussion] Allesa:
K2 gadgets is my YouTube channel but it is in Indonesian lol..

My wife's u11 on 8.0 suffers from this problem, but its not as pronounced. I can only experience it if I track REALLY slow and accurate, then the sudden jump in movement can be seen. not as pronounced as in the xz2.

The fact is that when we use touchscreen tester app, it detects instantly our finger touching the screen, but not detecting incremental movement after that. So I think it is not touchscreen lag. I think it's a matter of software problem, most likely a Google screw up. A driver/preference file such as this one https://www.xda-developers.com/fix-multi-touch-bug-google-pixel-2-xl-android-oreo/ may fix the whole thing.

It is like the phone intentionally disregarding slight movements on the screen as accidental swipes.

Why on earth this problem is not well known since it is happening in a lot of phones? I guess not many people move their fingers in such ways as avid fps gamers :laugh:
[Sony Xperia XZ2 Guides, News, & Discussion] tomo100brt:
I have this problem too. Can't properly play Street Fighter IV CE. After 51.1.A.3.159 firmware update situation is much better but not 100% good.
[Sony Xperia XZ2 Guides, News, & Discussion] eitama:
I remember in the old Galaxy S2 and the likes days, had the same annoying issue.

There was an App back then that resolved the issue completely - https://xdaforums.com/galaxy-s2/orig-development/ref-solving-touchscreen-sensitivity-t1161262

From what I gather, the minimum threshold to register a movement is there to allow convenient "Long Press". Long press is not triggered if the user for example is scrolling through home screens, so they added the threshold. If you ask me, long press should not be part of any touch os as it slows stuff down. Apple resolved it with Force touch.... (I hate apple and iOS)

On my HTC U11 i suffer the same issues, but I don't game much so I have not tried to fix it.

Also I have not tried but, maybe you should : https://play.google.com/store/apps/details?id=apps.redpi.touchscreenrepair&hl=en
[Sony Xperia XZ2 Guides, News, & Discussion] Seb122:
I tried touchscreen repair app but nothing changed after calibration... I doubt about this app, it seems to be fake. How does it work to modify touchscreen attributes without root acces ?
[Sony Xperia XZ2 Guides, News, & Discussion] nasko_spasko:
Same here

According to this thread, the value is set by the vendor and overriding a default one set to 8dip compared to 20dip in our device. In other words ACTION_MOVE event is not generated before the touch point travels the distance value in any direction. Might be wrong, though.
[Sony Xperia XZ2 Guides, News, & Discussion] MartinX3:
I also get the issues in my XZ2

I can't write fast with my keyboard.

Keystrokes are getting lost.

Thank you, but I need twrp or root to do this.

We don't have twrp and rooting/unlocking will kill our drm keys. :(
[Sony Xperia XZ2 Guides, News, & Discussion] MisterDams:
I'm not using much apps/games that requires precision, so I haven't noticed this. The only issue I had with the touchscreen of my device (XZ2c) was selecting the radio button for the APN selection of Network management settings, that required high precision, too much for such a basic action.

Has anyone tried to enable Glove mode ? It's supposed to increase sensitivity, so it might help until a better fix is found. Or actually be worse, if the phone considers "bigger fingers" and increases the dead zone.
[Sony Xperia XZ2 Guides, News, & Discussion] Flynnchen82:
Glove mode doesn't change the existant dead zone, was one of the first things that i tried with my xz2 compact.

Btw i got a small update (0,7mb) today but no idea what it's for. Same security level (1. April) and no change in the touchscreen behaviour.
[Sony Xperia XZ2 Guides, News, & Discussion] hotcakes_shinku:
Anyone tried the Android P beta for the XZ2 whether did they fix it?
[Sony Xperia XZ2 Guides, News, & Discussion] CaraMuuu:
I see the Android P beta thread is getting some activity, so we would be grateful if somebody paid attention to this. Thanks in advance to whoever will test it!
[Sony Xperia XZ2 Guides, News, & Discussion] Flynnchen82:
I would but since i own the compact there is no beta for my device :(
[Sony Xperia XZ2 Guides, News, & Discussion] Spam97:
Small update ...

I think the newest update 51.1.A.4.173 might have fixed the problem ... I have tried to replicate the original problem on this version but did not succed yet ...

Can anyone else try to reproduce it and report back here ?
[Sony Xperia XZ2 Guides, News, & Discussion] FuraX51:
I have mine (z2c) since a few days. It's an Rev. 3 model. Doesn't have any sensitivity problem. This phone is really fast and responsive. I play a lot on my phones, and this one is clearly one of my best phones ever
[Sony Xperia XZ2 Guides, News, & Discussion] MartinX3:
As far as I know is that it is not a Compact problem.

And the 51.1.A.4.173 didn't fixed anything on my XZ2 regarding this screen issue.
[Sony Xperia XZ2 Guides, News, & Discussion] Allesa:
P20 pro just got fixed. Waiting for Sony to realize the problem..
[Sony Xperia XZ2 Guides, News, & Discussion] Flynnchen82:
No matter of realizing it. Myself and some others had tough discussions with support until they promised to forward it internally. The question is more about accepting and fixing it.
[Sony Xperia XZ2 Guides, News, & Discussion] Greenarcher707:
Same issue with my XZ2 playing DBZ Dokkan. It misses my touch input.
[Sony Xperia XZ2 Guides, News, & Discussion] MartinX3:
They told me yesterday, that I need to repair my device after telling me, that an 1 month update had fixed it....
[Sony Xperia XZ2 Guides, News, & Discussion] Flynnchen82:
There is just no update by Sony that could fix this issue yet.

Apart from that the support has no clue.
[Sony Xperia XZ2 Guides, News, & Discussion] mirhl:
Didn't some guy said the same also happened on huawei and something else devices with oreo, just to be fixed in an update?
[Sony Xperia XZ2 Guides, News, & Discussion] Flynnchen82:
Yes, actually all Oreo 8.0 devices are to be affected unless it is fixed/changed/whatever by the manufacturer.

Fixed with 8.1 but other problems then.

But until now Sony did not fix it.

Just testing a LG G6 and can't notice it there. But i didn't on the U11 too although he said it should be also affected.
[Sony Xperia XZ2 Guides, News, & Discussion] MartinX3:
I will ask the support to repair my phone.

Switch it to the latest hardware revision.

And see if this fix my touch screen issue.

Others complaining that the hardware revisions 3 and 4 doesn't have this issue.

I own hardware revision 2 of the H8296.
[Sony Xperia XZ2 Guides, News, & Discussion] Allesa:
I think i said that :D

Anyway, just finished my oneplus 6 review, and yes it has the same problem...

Worse thing is, i havent seen anyone on oneplus official forum or here on xda mentioned the problem on the device..

So.. problem still exists in xz2 til now? I sold my xz2, planning to repurchase a preloved unit if it is fixed...
[Sony Xperia XZ2 Guides, News, & Discussion] Flynnchen82:
Guess you will have to wait a long time...
[Sony Xperia XZ2 Guides, News, & Discussion] faroit:
I have the OP6 (Can't decide which one to keep) and it does NOT have the same problem. The OP6 does not have any deadzone. However reaction time is a bit slower (or as slow as the XZ2). All in all, the touch screens on both phones react significantly slower then my four year old iPhone 6... oh boy...
[Sony Xperia XZ2 Guides, News, & Discussion] Allesa:
It does have a mini deadzone in mine.. 5.1.6 latest firmware. Not as bad as in xz2 tho.

https://youtu.be/m0Qfycg6vf4

As a comparison, this is what perfect screen sensitivity looks like on pixel 2 xl

https://youtu.be/NXjgVJ-KdgE
[Sony Xperia XZ2 Guides, News, & Discussion] stipi69:
Software update could fix lag i think but when screen heats ang fingers get sticky and kinda not able to follow your desired movement on screen, not a software on the world could help with this unless they throttle it down but then we gain and loose performance as was seen on Z5. Or maybe it is really about touch setting adjustmenst, looking forward to an update to see what happens

In prolonged play of Terraria when you have tons of micro adjustments it really gets annoying. If i use nails ( try it it plays great)
[Sony Xperia XZ2 Guides, News, & Discussion] FcukBloat:
for me and another guy in xz2c section things seem much better/fixed in latest .225 update.. do you experience better results as well or not with regular xz2?
[Sony Xperia XZ2 Guides, News, & Discussion] michal89chz:
Touch is fixed on last update.
[Sony Xperia XZ2 Guides, News, & Discussion] MartinX3:
Any other experiences?

At my site if I move my finger slowly, it makes first a jump before following my finger.

There is still a little dead zone.

Also if I use the grid touch test in the service menu and move my finger fast, it doesn't activate every cube which cross my finger.

I tested this multiple times.

Also if I write das on the keyboard, it ignores some key touches.
[Sony Xperia XZ2 Guides, News, & Discussion] kris555777:
For me it's not that issue, i moved fingers smooth
[Sony Xperia XZ2 Guides, News, & Discussion] MartinX3:
Which hardware revision do you own?

Here is also a hardware revision thread which shows you, where you can find your revision
[Sony Xperia XZ2 Guides, News, & Discussion] kris555777:
Model H8226 Rev 2
[Sony Xperia XZ2 Guides, News, & Discussion] MartinX3:
Mine is H8296 Revision 2.
[Sony Xperia XZ2 Guides, News, & Discussion] Allesa:
Oh nice, confirmed bro?
[Sony Xperia XZ2 Guides, News, & Discussion] FcukBloat:
for me also, xz2c. or at least I'm not having the same big touch problems i had before
[Sony Xperia XZ2 Guides, News, & Discussion] Flynnchen82:
Got my xz2c back from repair (actually a new device) and will test it back home. If Germany already got the update...?
[Sony Xperia XZ2 Guides, News, & Discussion] Flynnchen82:
Not fixed for XZ2 compact.

Just installed it on my new (guess rev.2) device and dead zone still there.

https://drive.google.com/file/d/1FzKAr4b1919OUAPbgADIZQZjVZJNNntW/view?usp=sharing

this is the behaviour i have now with latest fw, couldn't do these small movements with previous firmware... touch sensitivity was much reduced
[Sony Xperia XZ2 Guides, News, & Discussion] Haldi4803:
It's easy to test...

Go into Developers options and then activate the Pointer Position in the Input section. Now you have a X, Y, Xv, Yv and Pressure + Size in the status bar.

if you move around you can see it moving pixel by pixel. But if you point at something, wait a second and then move it takes a short delay and then jump 3-7 pixels.

i saw this on the 225 and it's still happening on the P beta....
[Sony Xperia XZ2 Guides, News, & Discussion] Flynnchen82:
That's tough. Thought it's meant to be no more an issue since 8.1 and now you tell me that P still has it :(
[Sony Xperia XZ2 Guides, News, & Discussion] FcukBloat:
doesn't seem to happen here, but maybe i didn't get what you mean. can you share a video of that behaviour you are taking about, so i can then test here? thanks
[Sony Xperia XZ2 Guides, News, & Discussion] Haldi4803:
This:

[Sony Xperia XZ2 Guides, News, & Discussion] FcukBloat:
i tried what you said but i don't see anything strange? no jumps or other. maybe i don't understand well how it works though.

https://drive.google.com/file/d/1ppOQzmvA4nl-7QoAKd4MCYLwwpgFLuLw/view?usp=sharing

in any case i confirm touch here is much better than before.
[Sony Xperia XZ2 Guides, News, & Discussion] Pandemic:
Uuuh beta 2 is already out and maybe its in beta 2 fixed.

Btw irs fixed on oreo to on fw 225 with June patch so far i readed it.
[Sony Xperia XZ2 Guides, News, & Discussion] MartinX3:
Readed or tested?

My XZ2 is not fixed.
[Sony Xperia XZ2 Guides, News, & Discussion] Luhccas-X10:
Touch is fine with june update.

I'm playing MC5 and the aim is a lot better now.

Sent from my Sony Xperia XZ2!
[Sony Xperia XZ2 Guides, News, & Discussion] FcukBloat:
confirmed. all people saying the opposite is not paying proofs it seems. look the attachment and compare it with the one in OP.. with earlier firmwares this was not possible at all.

this is the same you can see on the Samsung phone in OP so what's the problem people is still complaining about? this image confirms the problem mentioned in OP is fixed, at least for me.

you are maybe referring to a new/different problem now...
[Sony Xperia XZ2 Guides, News, & Discussion] Flynnchen82:
Don't have to proof, it's just the same as before on my device. Making an on screen video wouldn't help because you need to see my finger movements.

And i have a G6 to compare, with one device i can play Paladins Strike, guess which...

Why the bug is fixed for some people and some (including me) not would be interesting to know. Does everyone whose device was fixed have a rev1 unit? Mine is rev2.
[Sony Xperia XZ2 Guides, News, & Discussion] Flynnchen82:
Best i can do if you want a photo of mine.

See sometimes it also does small circles, but then i do have to move the finger a lot further.
[Sony Xperia XZ2 Guides, News, & Discussion] MartinX3:
One one Screenshot I tried to make little circles.

On the other one I moved my finger fast do draw a line.

And this buggy touch made two lines and other line strikes.

H8296 rev2
[Sony Xperia XZ2 Guides, News, & Discussion] FcukBloat:
so it is strange indeed it seems it is fixed for some and not fixed for others.. it may be really due to different hw revisions or touch panels so.. well in this case they should be on the good way to fix this for all..
[Sony Xperia XZ2 Guides, News, & Discussion] Haldi4803:
The thing is... it's extremly hard to test!

One moves his finger 8 pixels while some other moves his finger 12 pixels. if you don't have the exact same finger movement how can you say it' different or equal?
[Sony Xperia XZ2 Guides, News, & Discussion] Flynnchen82:
That's why i say you need to see finger movements when making a media to show how it works now.

Comparing it to the G6: There the screen reacts for every tiny movement, no matter how small it is. Put your finger on, move it 1mm (or less) to any direction and the screen follows.

I do have the feeling that the patch made the xz2c display a little better for touch. But on my device there is still a rather large dead area. Put the finger on, move it to any direction and the screen starts following after some mm (like 3-4). However, i could now do the same small movements once the screen started to follow. But for example gaming when you need high aim (which is already hard on the compact) is Impossible.

Maybe i can do a video comparison, but i'm not the video guy and it was already shown before.

I have access to many of these phones as I have to fix them at work. All of them got that issue, it is xperia thing- XZ series thing. Hard to reproduce few first times but when you catch it, then it will be an issue for you. These lines are only few secs on screen and most noticiable on grey notifications screen. It has something to do with temperature of glass surface and touch.

Did someone look, if this touchscreen bugs are caused by wrong build.prop settings?

I can't look into this file.

It is only readable by root and the newest flashtool, which supports the XZ2 now is still telling me, that the sin-version of the system image is not supported. (Issue ticked already written).

Newest sin images can be extracted with UnSIN, or munjeni's tool.

I attach here whatever relevant files I found in my very first XZ2c firmware.
[Sony Xperia XZ2 Guides, News, & Discussion] MartinX3:
Thank you, with UnSin, I extracted the system.sin

I didn't found the clearpad.idc, but here is the build.prop from the H8266 German Firmware.

Maybe someone start playing with the config values and a unlocked XZ2 to adjust the touchscreen sensitivity and also report if it change the battery consumption.
[Sony Xperia XZ2 Guides, News, & Discussion] mirhl:
.idc is in the vendor partition in \usr\idc\, and that's what actually handle touchscreen (as can be seen in dumpsys input)

Documentation is here: https://source.android.com/devices/input/touch-devices#touch-device-configuration

Besides, after some archeology around firmware directories, and some google-fu, I think the phones should be using TD4353jdi touch controller (like you can even easily see from the service menu info, duh)
