Hi all, can anyone who owns the tablet check if your set has this issue as well? I'm using the Mediapad M5 Pro.
Basically on my set there is a problem with the touchscreen whereby when making small adjustments, changing directions with small movement will cause the touchscreen to hang and cause the touch input to jump a few pixels.
Any help would be appreciated as I'm trying to figure if this is a hardware issue with my set or if its a software issue that affects all M5 Pro.
I have an inkling that this could be caused by palm rejection configuration of the tablet that is overly aggressive, causing the touchscreen to bug out as such.

My M5 Pro is having this issue too...
Afaik there is a threshold level when to recognize an input as a "tap" and when as a "swipe/movement"
We humans are too inaccurate so that one tap often contains a movement by accident. To cancel that out minor movements are still considered taps.
Would be interesting to see if it is the same on lineage OS. If it is,then the reason is probably palm rejection or some weird thing. If it's not the reason is most likely how Huawei calibrated it.
At least that's what I think without any proof

Good point, but the thing is the jitters still occur after I start to scroll the pages. Afaik, upon the very first contact against the digitizer the system should identify if its a tap or scroll input. Once a scroll input is identified, the consideration for tap input should be nullified.
In that case if we were to refer to the videos I shown, as soon as my finger taps the screen and starts scrolling, the digitizer should be relaying information to the phone that it is a scroll, there is no reason for the phone to think that I am still performing a tap after I have been scrolling around without lifting my finger off the screen.
Of course, I am no coding expert and what I am stating here is based on logic and my limited understanding of computer language. So my point is I still think it's a software bug that Huawei needs to address and as evident on their past phones (P20 Pro, Honor 9), it is not the first time bad touch firmware has been heard of on a Huawei device.
**Another point is that if you were to perform the same test but instead with the M-pen, the touch screen would work just fine. But stylus touch input runs differently from finger touch input, so I am not too sure about how to comment on this.

I agree with you. They managed to fix the emui touch bug though where two simultaneous inputs were denied after a short time. (also was / is on the p10 and other emui devices)
And that's why I was curious about lineage OS.
The pen works with a different digitizer though. So different production, drivers etc
Not fixed even with the latest update with Gpu turbo...
anyone have solution for this??
i don't know if this is solution but there is 1 option. I don't know how is in english because i have polish language but if u
Polish - Ustawienia - inteligętna pomoc - Ułatwienia dostępu - Gesty powiększania

when I have this option turned on, the touch screen responds very strangely and with an delays in all apps (games too)

Hi all
Not sure if its the correct place to put this but whatever.
My android device (Archos 70) has a glitchy touchscreen. I'll explain..
1:When i press down onto the screen for a while and lift it up, (long enough to trigger the long hold function or just performing a very slow swipe) it will not register any touchscreen input for maybe a second right after i lift my finger up.
2:Also, the touchscreen algorithm is odd in such a way the "touch location" lags a little behind my finger when i slide. not lag as in slow, but if i were to slide my finger upwards and stop, the "touch" will be below my finger. It definitely is the algorithm's fault...
3:Both are NOT because of badly written third party apps.
My android phone responds immediately but this device has a lag..
I cant take notes or use handwriting apps this way..
Help? Anyone? Any "drivers" or hacks???

If you look around XDA or ask someone, they could add tweaks to your build.prop to increase scrolling smoothness
If you have your bootloader unlocked and a custom kernel on then you can use init.d scripts which will drastically improve the performance of your device and scrolling should feel a lot better. Providing the kernel supports it....
Anyway you are better off contacting a Dev for your device over this as it voids your warranty and I don't know if this can be done on your device whatsoever

Moving to Q&A
Has anyone noticed a change in how the touchscreen behaves after installing ICS?
It seems to me that it is biased a little more towards interpreting a touch as swipe or scroll rather than select. For example clicking links in a webpage or tapping icons on the homescreen seem to require a much more deliberate effort to select/open. It's not awful, but I would like to be able to bias it back a little more to selecting rather than swiping.
Is there a setting for this anywhere or an app available that allows adjustment?
I would to know too.. I hate this..
But it's not just from latest ICS 4.0.3 International, the Beta version also suffer same thing.
Is HC not like this? (I upgraded to 4.0.3 Beta as soon as after bought Mediapad )
Yes, I noticed it also. When you turn on Settings - Developer options - Pointer location, it clearly shows how your clicks/dots becomes swipes/lines.
yes, you're right.. it sometime (most time ) cause texting experience not so fluid (letter not appear as it's detected as swipe not click).
got the same thing.. i've changed the launcher, so with the Apex launcher it's not that bad in the homescreens.. when i enabled the option to show "pointer location" i can see the "tap" as a line, or a "swipe" line :\
tried the same on my Galaxy S, and all the "taps" are only a small point.. it's much better than on the MediaPad.. i hope it's just a software issue and it can be solved..
maybe, we could try something like "screen booster" or "touchscreen booster" from the Market (Play)
Erratic screen while charging
The other thing I've noticed after ICS international is that the touchscreen is now erratic while charging and in a case. I believe this is a common problem with capacitive touchscreens, but hadn't noticed it until after flashing ICS. It is not an issue if I remove the pad from the case and hold it in my hand.
Anyone else seen this?
This sensitive touchscreen isn't Angry Birds friendly. Constantly shakes a little bit.
soooo.....is there any solutions?

Not unless huaweis coders tweak it or releases the source code.
Bear with me here, this issue is kind of hard to describe. When I am playing a game that requires touch inputs from both hands, I often get bugs. It's most obvious in games that have controller-style overlays. As is normal, I am using my left thumb to tell a character to move right or left, and then I press the button on the right to jump. However, when I release my jump, I stop running. The screen no longer recognizes that my left thumb has been pressed down the whole time and should still be moving in the direction I am pressing. This happens in Bean's Quest, Chono'n'Cash, Delver, Gunman Clive, and any other game of this nature I have tried on my device.
I played some of these games just fine on my old Evo. Is anyone experiencing this issue? I experienced it on stock as well as several custom roms I have tried.
Turn off "Htc gestures" you'll find it in settings, display & gestures!
When the display senses three finger inputs it renders it touch inputs useless...run a multi-touch test app and you'll see.

Doesn't seem to have fixed my issue, I am still having problems with some two finger games. I will be using two fingers just fine, when I remove one finger from the display the first finger is no longer recognized even though it is still touching. I have to remove the first finger and press it again every time.
Do U have any type of lock screen installed. If so uninstall. Use only stock.

Moving to Q&A
I encountered this recently
It seemed to get "stuck" after using multi touch gestures in-game. Tapping the game with two fingers often "unstuck" it, but overall it was extremely frustrating.
This was on an APK not designed for the phone, though
Sorry to bring back up an old thread (is 6 days even considered old?) anyway you HAVE to disable the HTC 3 touch setting gesture because it will ignore anything more than 2 (3 will only register if you swipe up or down, but sense itself registers it, nothing else).
Just made the video below as proof (forgive my foreign accent xD):
Our screen supports (at least) 10 different points (was going to try 11 but I could not get my nose on the screen with my fingers and my girlfriend is asleep).
EDIT: Two things, one: I had widgetlocker installed while I did the above video, it caused no problems. Two: the maximum number of inputs our phones can handle is 10, incase anyone was curious.
EDIT 2: While I don't have the issue with widgetlocker it seems that it is a known problem, but you don't have to disable the lock screen altogether. Go into widgetlocker settings> advanced> retain system key guard. Source: http://forum.xda-developers.com/showthread.php?t=1652038

Did you try my edit 2? The Retain System keyguard? I can assure you that I have Widgetlocker installed and I have the 10 inputs (that video was recorded with widgetlocker running).
[SOLVED!] - HTC Evo 4G LTE touch screen trouble - WidgetLocker is the problem
Retaining system keyguard in WidgetLocker worked for me! Thank you for this Racer for All. (Actually I found your YouTube video, and a link to this thread)
I was wondering why all the games I played all of a sudden stopped functioning properly (in terms of touch controls... Example: MineCraft PE, moving forward and trying to look left or right - suddenly character would stop moving.)
Sorry to dig up an old thread, but I want people to know if they have WidgetLocker (and don't want to uninstall it) just go to Settings - Advanced - Retain system keyguard - zmag
What is the nature of touch handling for android? Is it device specific as different displays are used across devices? I am trying to find where exactly in the massive mess that is aosp I should look to find the code relevant to touch/gesture detection. Currently really frustrated with my nexus 9 as the touch detection is ****e. I turned on pointer mapping in the developer options and it appears that the moment you touch the display it tracks a point and waits to see if its a swipe or single touch. The travel needed to tell it that you are swiping is very substantial and it only seems to track 2 points for this large travel. The reason this is frustrating is that when you are writing with a stylus or what not, every letter must start with a straight line segment as it detects that you are just touching the display vs swiping. Handwriting degrades and writing small curves becomes nearly impossible. I would like to take a look at the code that handles this but can't seem to find an easy way to browse aosp. Don't even know if at this point it is a fault of the android system, the kernel, or just a hardware limitation. I appreciate any assistance
Anyone?
First of all, thanks to @xtermmin for pointing me in the right direction for this.
Steps to increase touch sensitivity and get DTTW functioning better:
Download Shortcut Master Lite
Hit the ellipsis at the top right and click App Explorer (Yes to the error)
Tap anywhere to get the loading circle to go away and find something called Force Touch
In the Force Touch menu, select ZteLCDPressureSettings and hit Launch
Here you will find some options.
Tap Pressure Sensitivity and move the red dot slider all the way to the left where the green "Light" is.
Back out of the menu and you are done.
There are some other things under features that may be of interest as well to some people.
Additionally, there are a couple other items in the Force Touch menu that could play a role in ROMs down the line. The "Press Image" option has a toggle within that item but it does not stick upon backing out and reentering the menu.
If you find anything else of interest, please let everyone know so we can make this the best phone we've ever owned.
Thanks!
Awesome, T2W works better now.... Thanks

This definitely helped! Kinda odd that there is a slight delay from when you double tap and when it actually wakes. I remember the LG G2 responding more quickly with this feature. Also miss the double tap to lock screen too that almost no other phone had (though with nova launcher and an app, you can do this). Regardless, I'm glad the functionality is there.
What's interesting about this little hack is that it clearly is using the force touch settings that will be found in the 6GB RAM model that has a force touch display. Funny how it remains in the ROM anyway, just tucked away since this model doesn't use force touch.
Can I remove the vibration when I use the double tap to wake?
This has made 0 difference for me. I've got a 64gb US variant. I've also noticed double tap to wake stops working when the phone is in Doze. Anyone else have this issue?
Same same with doze, but when my phone isn't deeply asleep this tip indeed increased touch sensitivity.

It's there by default on the US model, at least.
While this definitely improves DT2W functionality, it's still temperamental. I find that now it responds best to very light touches, but harder taps are ignored. If I tweak it to be less sensitive, it does exactly that: it requires a harder touch at all times. Why can't it just respond to a range of touches? My G3 worked just fine in this regard.

Totally agree with this. It's still very inconsistent, but mine does work if I slam it twice as well as tap it lightly twice. It doesnt always work and it's still delayed. This was sort of a bandaid for a bigger problem though. I hope CM, and ....probably nothing else? at this point...can address it further.

At EU version I don't see any option for vibration so far.
But totally agree I would like to be more response to a range of touch.
I remember when had LG flex 2 was better implementation than ZTE.
Hope future update improve that.

Quite honestly, the Axon 7's story is perpetually: "[insert company here] did a better job of implementing [insert feature here]". There is very little (if anything) that the Axon 7 does better than the big manufacturers, IMO. It does a passable (sometimes even decent) job of most things, though - and at an appreciable discount - which is why I still have mine. It's a budget flagship. It's high-trim Toyota versus a Lexus. Add to that the potential for improvements via software (which is the source of many of my complaints, really), and I think it's a solid buy with quirks I'm willing to live with for a little while as ZTE steps up and makes improvements.
Yep exactly from hardware point is very very capable device but from software although it's pretty good level but there's still staff for many improvements.
Axon 7 is my first Chinese smartphone from Chinese company until now and I'm quite pleased with the all package offering having it 5-6 days,but I would like to see from ZTE much more effort and listening the user base and bring as much improvement and tweaks to the software.
