Hi All, am a new member to this website. I've been reading all the threads related to my device (Xperia Ion Lt28h) and actually installed a custom ROM for the same for the first time. The ROM i chose was http://forum.xda-developers.com/showthread.php?t=2616450. It is actually cool to use. I have the kitkat feel in my phone but lately I've been experiencing some issues with the ROM. I tried to reply in the same thread but the usual 'New members with less than 10 posts' thing popped up. So i couldn't find any other way to ask someone regarding the issues that am facing. As am new to this , i may know how to contact someone or how to post it in a efficient way, if there are some, please let me know. If not, the below are the problems am facing and am seeking all the seniors help to solve it.
1) Sometimes, when am getting a call, phone rings, vibrates but the screen is still in standby mode and it takes around 5-10 seconds to see the caller info. This happens in 70% cases.
2) Camera doesn't work properly. In JB holding up and down the volume button zooms the camera but here it is taking picture. Also i searched if there is any option to zoom, i couldn't find it.
3) Some of the applications doesn't work. For Ex, Super beam is not working, as soon as i scan the QR code from other mobile to receive a file, my phone gets hang and gets restarted.
4) HDMI is not working, which was working in JB.
All these are the issues am facing. Please help me.
Hi, i have the G920F, i was wondering if there is a way to re-collaborate the touch screen, the issue i am having is on some games such as boom beach where i have to tap a certain little part of the screen and sometimes i am having to tap 3/4 times before it seems to register, on my older s4 this was perfect and registered first go everytime.
I just thought a re-collaboration may sort it?

I think you mean recalibrate. There is an app called Touchscreen Calibration that claims to do that sort of thing. I can't say I've used it as I've never had calibration issues.
Hello,
For touch screen problem try this:
-in dialer type *#2663#
-TSP firmware update (general)
You should see "PASS"
That have solve my touch screen problem...
Holy crap, thank you. This fixed it. I love you.
Made an account here just to thank you.
Thank you, this fixed my issue of no input detection on letters Z X D F C.
Hello. I have an Nvidia Shield tablet k1 on lollipop 5.1.1. Everything is great about this tablet except the touch screen. It is really sensitive. Also, when I am scrolling, it "jumps" and goes faster than I actually scrolled. It scrolls faster than it should. I found this thread on xda. It helped a little with the being too sensitive issue, but scrolling is still really weird. This is my second device since the first one's micro sd card was defective. They both are like this. Is there anything I can do, or do I just have to deal with it?

I was opening a thread with this exact same issue. I'm not on stock though (using the latest CM12 nightly), so I don't seem to have the 'Sensor Calibration' option.
Also the touchscreen seems to register a touch even when the finger is not touching the screen.
On the other hand, if I scroll a very small distance (like 0.5 centimetres) the list I'm scrolling doesn't move at all. This doesn't happen on other devices such as my Nexus 5 and Nexus 7 and is very annoying in some cases (some games, or moving the cursor for keyboard input).
I'll try to record a video of this behaviour.
What can we do to fix this?
Update: found a video (not mine) showing the issue I'm talking about: https://www.youtube.com/watch?v=08uPtusOJHQ
anyone else with this issue?
I also have this issue on/off sporadically on stock rom.
I'll be scrolling and itll jump back the opposite direction
Its like it looses track of the touch then catches it again.
It's irritating as my S5, Nexus 2012 have no problems scrolling smoothly.
I don't recall the original shield i tested in store to have this issue either.
Currently having amazon ship me a replacement to see if its just limited to the one I received. (QA issues)
Calibrating screen might fix the issues: go to About in settings and tap on model number until the calibration screen comes up. then hit calibrate. don't touch the screen then when it asks to reboot, reboot.

Did it fix the issue I posted the video about? I'm on Cyanogenmod now so I don't have the option to calibrate the screen, but I would consider going back to stock if it fixed this issue...
Calibration doesnt help at all , same issue at brand new k1. Nvidia says thats normal functionality lol
Yeah, very normal for a gaming tablet which would require precision...
Not trying to take up for this thing but I haven't had the first touch screen issue with it . so maybe not all is affected?? I've tried to replicate the issue but just can't everywhere I touch and slide is smooth
You mean it doesn't "jump" like the OP said? I don't seem to have that issue either.
I'm more concerned about the touchscreen's precision, as shown in the video.
Is there an app/code/apk that can disable touch input in a specific area of the screen on my unrooted Huawei Y6 Pro? I would really like an answer as soon as possible.
Also, if it helps, this is a physical error in the screen and it phantom touches in one particular area very time, so please don't suggest some sort of software fix. What I'm actually looking for is to someone suggest an app like Tasker to set a little dead zone where the phantom touch is.
So, in a nutshell, I want to disable a part of my touchscreen, not using rooted methods, so that every time I touch that area on my phone it does not respond and doesn't receive it as a touch.
Thanks for the help.
Got something
Hey bro,
You got something about your problem!!
Install partial screen app from playstore
Those who don't know there are some people having ghost touch issues on POCO f1 and one guy able to capture it on the video. I personally didn't had the issue but after trying I was able to recreate the issue on my device. soon after I found the cause and able to fix the issue. this may or may not work on your device but absolutely worked for me. this seems to be a software bug. and no-one needs to panic. hopefully it will be fixed in next update.
how to recreate the issue?
Steps
1. download a multi touch tester app I used this
2. first do some testing yourself see if you can spot the issue
3. now do 3 finger swipe down (phone will take screenshot)
4. now randomly touch your screen with 1 or 2 fingers you'll notice 1 or 2 ghost touches.
How to fix Fix it?
Steps
1. go to settings>additional settings>button and gesture shortcuts>take a screenshot
2. and set it to none.
3. reboot
that's it!
the issue should be fixed
please let me know whether this worked for you or not
Yes.
As you mentioned issue was there.
But fixed with those steps.

Good stuff. I was skeptical at first since I knew something was off sometimes. Thanks for confirming it. Should be fixed if they took notice of this bug.
Thanks! The issue is 100% reproducible with the app. By turning off 3 finger screenshot shortcut, the issue goes away.
Guys, please file a bug, so this can be fixed and we can go back to using this feature.
1.Yes, that issue is due to the screenshot feature, but shouldn't the phone be able to distinguish between 3 finger touch and more than 3? Either take screenshot on four finger swipe or register it.
2.Can you please confirm if there is accuracy problem in PUBG aiming when you use multitouch? Like the multitouch bugs in Pixel and Zenfone Max Pro but quite subtle, the thing about the other devices are, they look and have been acknowledged by the respective companies regarding the issue but in our case, Xiaomi or Poco is making no announcement or anything.

The issue comes up after taking a 3 finger screenshot, but disabling may not be the only solution as this feature is quite useful also
What I have noticed is that after taking screenshot ghost touch is there till we use 1,2 or 3 fingers. Once we use 4, 5 or higher fingers the issue goes away.
Isn't it better to just touch screen with 4 fingers after taking a screenshot which somehow resets the ghost touch issue.
Have tried this solution with multi touch tester app
Mine is just fine even when 3 finger swipe screenshot is switched on
I can confirm that ghost touch issue still persist even when disabling three finger screenshot.
Mostly visible in pubg.
Great, fix worked
I didn't relize the issue but nice posting
Stop it! This is not an issue. It happens on mostly every phone that supports gestures. Test it on OnePlus 6 and you will get the same result.

Okay, show me how this affects your usage of phone. Don't show me on touch testing apps. Show me a real use problem.

Exactly! There is no need to prove this issue because Google itself confirms that they have done a mistake by releasing it in Oreo and they have also promised to give a fix in later Pie updates. And people who wants proofs can look up in the internet about the "Multi touch Oreo Bug" problem and how it effects user experience rather than spamming here to make a point.

Dude, google fixed the issue in the May or June patch and all other OEM's had to merge their builds to fix it. The problem is not there in MiA1 or MiA2.
Here is the bug:

Thanks
Maybe the original solution for 8.1 and P devices will work for this? It will either cause a bootloop, do nothing, or fix it... worth trying! Obviously an unlocked bootloader is needed for this (Magisk).
