Multi touch issue - Android Q&A, Help & Troubleshooting

Every time I touch 2 fingers together in the screen it registers 2 or more touches (ghost touch) but when I charge my phone the problem is not there. the multi touch problem goes back when I unplug the cable.

Actually this is probably a hardware problem
I have only one solution that can be tested without hardware
Go to Settings -> Developer Options -> Enable Force 2D GPU Rendering
Hope this helps
If yes then please press the thanks button

Menu -> Settings -> Lang&Keyboard -> Touch Input -> Text Input -> Calibration Tool
First do the "Reset Calibration" then do your own calibration is how I did it.

That's for the HTC Keyboard ONLY. THat has no effect on anything else.
And no, there is no way (or need) to calibrate the screen.
The dialog says for the tool says "Calibrate your screen for a better touch experience".
While I did not design the phone or interface, I don't know 100% either way and luckily, it can't hurt.
*If you did code the interface and know for sure, thank you. ;-)

I wish there was a way to calibrate the touch screen. Anyone else having issues where you press the top thread of SMS and it goes to the 4th one down and then it locks the screen like it's touching there so I can't press anything else? No back button, home button. Only thing that works is locking it then unlocking but sometimes you have to do that 3 to 4 times before it will stop "touching" that same spot. I haven't hard reset yet but if that doesn't work I'm going to have them replace it.
That happened to me a lot with the original evo, not as bad with this one, but it has been off a few times

Are you daft? It calibrates the G-sensor, as in the sensor that reads the G forces the phone is being exposed to.

Nope I have the option as well. The feature is offered on most stock based roms I believe.

It sounds like your digitizer (touchscreen interface) may be going out. Try to calibrate in the keyboard settings and then calibrate the "g" (accelerometer) sensor. If you're still having issues with p,0 put your phone in landscape mode where the home button is on top and confirm that area of the screen by pressing the comma or space bar. Good luck.

You might also try a Gingerbread Rom as I've noticed the accuracy to sometimes be off on ics Roms, especially near the screen edges. Or, maybe try a different keyboard.

[Q] Serious multitouch issue - most obvious in games

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.

Appears that widgetlocker is the culprit! Is this issue documented or known, exactly? What causes it? Thanks so much for the help. I will surely miss widgetlocker.
Please use the Q&A Forum for questions &

Thanks ✟
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

[HOW TO] Increase touch sensitivity and Double-Tap-To-Wake Functionality(Force Touch)

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
P. S. Adding your thread to my all in one place guides.

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.

EMUI 10 Desktop mode mouse speed

Hello there,
I have a little problem since I have updated my mate 20 pro to EMUI 10 : In desktop mode, the mouse is simply not utilisable. Even the slightest move make the cursor go in every directions possible at near light speed. Same with a touchpad. But if I only have a screen plugged and I'm in phone mode, the cursor move like intended. Only in desktop mode show crasy moves. Someone has an idea ? Desktop mode is usefull for me but only with a keyboard and mouse plugged in...
Thanks !
I'm having the same issue. In EMUI Desktop mode, mouse is all over the place and not usable at all.
Did you find a way to fix it ?
cheers

Yes. Sadly I had to do a factory reset. Problem gone since

yes this solved a lot of my problems including the mouse speed.
Nevermind, problem just appeared again, didn't do anything particular though
EDIT : Changed "smallest width" in developper options and backed it to 360 dp solved the problem. Even if it's temporary, it's still better than a hard reset
un-tick the "switch access" in your phone. Works well for my p30 pro.
resolution problem
change ur resolution to 1080p problem will be gone
Resolution
I change the resolution on phone settings and was ok. Thank You
For me, changing the resolution solves the problem temporarily. The problem can randomly reappear even when using the desktop mode. That's really annoying. Another problem that I have is that browsing applications like Brave and Chrome stop rendering webpages when the phone screen goes off. When the screen turns back on, the rendering completes. Can anyone test and let me know if there's a solution? EMUI 10.1 latest
I'm using EMUI 11 but should be same.
Settings -> Accessibility Features -> Accessibility -> Large Mouse Pointer
After that works fine.

Mi note 10 lite touch lag-delay-ghosting

I have this problem mostly when i type on keyboard.. sometimes i have to double press the letters or some ghost touch happen while typing..
Im sure its not hardware issue because problem is not there always and it happens mostly on keyboard.
If you guys have this issue please vote here https://c.mi.com/thread-3194087-1-0.html so they give some attention to the problem.

I use swift key.. same on all keyboards.. lag-delay and sometimes ghosting while typing fast.. super annoying.. mi 9 lite was much better.. hope it gets fixed
I experience this issue mainly towards the edge of the screen. So I installed SwiftKey and resized the keyboard to fit only to the flat part of the screen. I think it's better this way.
after that i think the best thing is to stay with my lovely mi 9 lite, even if i don't like the thing that it doesn't interest too much devs for roms and modded apps like gcam lol
