[5Z] Touchscreen response is improved but not fixed yet.

Level 3
The device in question is an ASUS ZenFone 5Z 4GB/64GB, unrooted, updated to 100.10.107.87.
In the latest firmware update, which I'm running now, an improvement was brought to the touch panel response. Very welcome indeed.
But this improvement was not a definitive fix. In fact, it's not like before, but the problem still exists. You can still feel the lack of fluidity in the response from sliding your fingers on the screen.
For better reproduction, do the following multi-touch test on the tool accessed through the calculator:
- Put three fingers together, very close together. (Also works with two, four, etc.)
- Place them on top of the screen.
- Slide them slowly to the bottom.
- This problem does not affect the sliding of the fingers while they are separated (or the effect is less noticeable).
Another problem still present is the delay, which can be reproduced in the same tool, as follows:
- Start by sliding a finger across the screen.
- As you slide it, add a touch.
You will see that the response to the sliding finger will stutter before it returns to accompany the finger.

Yes I noticed this too. I have tested this also.
Let's see what mods reply on this topic. 🙂
After updating to latest .87 please check recorded videos for multi touch issue (not fixed)
Case 1 :-
Put three fingers together, very close together. (Also works with two, four, etc.)
Case 2:-
This is multi-touch issue 👆
JITTERS IN PUBG:-
jittering in pubg during right left recent update .87 says it is fixed but according to me it is not fully fixed but is minimised a bit jitters do exist even after .87 latest update in pubg (but it is less than before)
I ALSO OBSERVED JITTERS ARE LESS IN DOMINATION MODE IN PUBG THAN CLASSIC MODE
For classic mode movement of eye icon slowly Also looking left and right slowly during running those both conditions still jitters
Tried reinstallation of game after latest .87 update
@Anders_ASUS @CH_ASUS
Me too noticed this. I wonder if it's a hardware or software issue. Never heard this type of issue in other phones. It would be nice if ASUS explains the problem here.
Oi de novo, @gabriel_prado, se puder me jogar de volta pro EN*, agradeço. Essa é uma questão que já vem sendo discutida há meses entre eu, os marcados acima e os moderadores que também foram marcados.
Eles já sabem como detectar o problema (e demorou pra que isso acontecesse).
O post foi feito em EN e perde engajamento, não só pelo idioma, pelo baixo movimento do ZenTalk PT.
Ainda assim, sua ajuda será muito apreciada. :)
*Não sei quem me jogou pra cá.
It's under investigation. They fixed the initial bug. I shortly after realized that there was a 4 or more fingers bug. However, I see now that you have found two seperate bugs. The single slide with simultaneous tapping bug and the very close three or more touch slide. I will add these two to the investigation.
Please let me know if you have any new findings
@Anders_ASUS someone moved this thread from EN TO PT forum can you bring back this thread to EN so that it will be easy for us to keep u updated with problems and findings as we are alredy disscusing since last months
Thankyou 😊
They also played me for PT but there is no movement there, if this way I will not collaborate anymore :(
Dont worry now this thread is in EN
Thankyou😊
Thank you one more time!

The delay seems like the panel is scheduling touches.
You start to slide a finger (the panel call it "1") while sliding you add a touch (and instead calling it "2", the panel ignores the sliding finger for a milisecond to call the touch "1", and then calls the slide "2").
--
The flickering just seems the same as it was, but now lesser with the fingers separated, but when they are close it starts to flick, seems like the panel is confused if the close fingers are multiple or just one (remember, happens with 2, 3, 4 fingers close... or any number you add, it just gets worse as you add fingers).
And still there is a issue when attending calls in earphones...
As I play PUBG mobile with 4 finger claw sometimes display doesn't accept the touch request. Touch latency is still there wven though our phone can achieve 60fps whle playing TDM in PUBG mobile.
Let's see what more details we get. 🙂
I am not playing games with this phone ! Terrible experience. I Don't never buy again Asus ! Zenfone 5z terrible touchscreen lag -_- If play moba games terrible Zenfone 5z ! Please update -_- Samsung note 2 better > Zenfone 5z touchscreen , multitouch , lol .
I use last update but very little improvement , not fixed -_-
@rskiron42!
Please, give more details about your experience with the touchscreen here.
If you could record videos of the issue while it happens, it would be great too. (Same for @burakterzi91.)
Okay watch video , lag + lag lag -_-
asus officials hopefully fix this lag(error) multitouch, touchscreen terrible.
Terrible experience games Asus Zenfone 5z -_-
Using the multitouch tester app, if you drag 1 finger across the screen there is a lag but the experience is still smooth. Using 2 fingers also it is smooth and usable. But on using greater than two fingers the touch input circles follow your fingers in a shaky laggy fashion with considerable jittering. Feels like you are using a phone with a spreadtrum processor and 20hz screen. Its terrible. Kind of wondering if the issue is just with a bad touch panel being used. Would like Asus to disclose if this is indeed a software issue. Waiting for a fix since forever.
I have no hope of updating. This problem is close to 2 years.
We've shown to moderators what it was and it got improved in the latest firmware, but not fixed yet.
One of the kindest moderators (@Anders_ASUS) said this after seeing our thread:
I hope they'll find and fix this as soon as they can. xD
It's not the panel, as devs improved it by software. But I still believe, if the optimizations on the touch firmware weren't enough, maybe it's the CPU/GPU that needs to be optimized.

CPU because the scheduling I've explained previously:
"The delay seems like the panel is scheduling touches.
You start to slide a finger (the panel call it "1") while sliding you add a touch (and instead calling it "2", the panel ignores the sliding finger for a milisecond to call the touch "1", and then calls the slide "2")."

GPU were pointed before by @bharanivijay69, could be an inconsistency in its clocks.
