Lately I have been experiencing a multitouch problem in my xperia play.
I was playing a touchscreen game when the controls were lagging and would get stuck on the screen. I thought it was just the game but to make sure I downloaded this multitouch tester application.
I will explain to you what you should do to replicate the problem.
1. Touch the screen with a finger (Finger A)
2. While keeping Finger A on the screen touch the screen with another finger (Finger B)
3. Do not remove finger A while tapping the screen with Finger B
4. The colors of the dots that indicate the fingers on the screen should change for Finger B after many taps with finger B the application will crash.
What is happening is that every time you remove then press Finger B while keeping Finger A pressed it thinks it is a new touch point think you have 3 or more fingers.
If you use this application to test. You will see it is giving Finger B a different ID every time it touches. This application does not Force close but it starts finger B at ID 0 when it reaches the maximum.
I did a google search and found this information.

^^ That is specific to the Xperia Play so you might want to read through it.
I may be able to get a video of it later.
You pointed me here from my keyboard problem. But my problem also occurs when I'm using just one hand. If I am just using my right thumb and press the delete key, it will sometimes register both the delete key and the button z. Same occurs for example with p and q.

but have you tried what I said about leaving 1 finger on at all times then tapping the screen with the other finger?
This can get very bad in racing games. You are holding the accelerator and tapping the brakes. Eventually the controls go crazy.
And 1 year later... I have exactly the same issue on my Sony Xperia U. After 3 taps of my second finger, multitouch didn't detect anymore my second finger.
My Xperia mini pro havn't this problem, this is very troublesome.

Lock and unlock the screen and it will sort it. Just do that every time it happens

If you load up Google Maps and just tap the screen twice it zooms in the same as the video shows. Plus it will not zoom out using the pinch method. I think it is just recognising two presses on the screen and not any form of multitouch?
i will try it and see
Yeah its fake. Its just a double touch.

it recognises the second finger as a second tap. no matter how hard you try you WILL touch it a fraction of a second later with the other finger. either that or when you swipe/pinch, it notices two consequtive movements but only registers them after eachother - double tap!
yes work for me
I try it works but only slightly touching the screen with two fingers! TRUE is not a joke! try like this and told me if it works for you too!
ONLY IN GOOGLE MAPS AND ONLY FOR ZOOM IN!! zoom out not work!!
Anyone else have issues with their Delete key? It seems I have to hit it twice to get it moving. I can type very fast and smooth with easy button presses, but the delete key seems to be a PITA.

Don't have any problems here with any keys (that I've found so far). Is it a case of since its a little more difficult to get to (upper right) corner that you don't realize you are not pressing it the same way as the other keys?
Just a thought.
No problems here
Never had that problem.

Hard keyboard or virtual? I haven't had that issue with either. Off topic, but my spacebar on the landscape virtual is a pain, I always end up hitting the b or v.

If you're not using a custom keyboard, have you tried calibrating your keyboard at:
Menu-->Settings-->Language&Keyboard-->Touch Input-->Text Input-->Calibration Tool
(Interestingly enough, Calibration tool is only available if you hold the phone in Portrait and not in Landscape)
Yeah, that was the first thing I tried. I'm going to try it again. Coming from the Hero and having the tight sliding due to my case, its going to be hard to get used a the hard keyboard again. It is weird that the calibration only works in portrait or w/e you call it, the Hero was the same way.

i think it might be that I'm just not hittin it right. I was typing last night and when I hit delete it worked right away. I just might be hittin it off center.
Hello,
SGS2, has a bit lag with touch dragging over the screen.
I will explain : try to touch any movable object on the screen, for example a scrollable internet page.
Now try to move your finger up and down, up and down, for a couple of time,
you will feel a little bit delay of the moving object.
Now, I did try MIUI for example, and the problem doesn't exist.
So, this is absolutely software issue, I guess the kernel is responsable for that.
Is there any solution for this one ?

Thanks, but this is not exactly what I meant.
Even when the screen begins to move, and you are moving your finger, the screen is moving lazily after your finger, and not like it was stuck to your finger as it suppose to be.
Maybe is't a performance issue, but, again, in MIUI for example the screen moves as it was stuck to your finger.
Also for me it seems to stutter for the first second or so after touching the screen, then going smooth as butter. I haven't tried any custom roms so I don't know if it's a software issue or not.

Try that app, as I remember something like that, and changing it to 0 or 5 fixes it.
Or try a custom kernel with the fix applied.
this might be because the touch system is figuring out if you're doing a CLICK or a DRAG or a SLIDE or whatever. it will take around half a second for it to figure out if you just touched the screen once or you held down the screen and slide it across.
Some kernels address this issue , most roms will have it fixed and those who don't just flash different kernel , only stock rom will have this problem.
The touch input in this device is so bad i have to use my stylus pen to browse webs(i can never touch the back page button on google chrome instead it touches the forward page button instead),close programs(touch the top of the screen and pulling it down never works), opening the charm bar(swiping my finger from the right of the screen to the left never works too).
I tried calibrating it by searching calibrate on the charm bar's search feature but they doesn't work as well.
Any way to fix this? Its getting so annoying because i can't use the touch screen feature at all because its not precise.

Dont have one myself, but I played with one at Frys, and I gotta say I didnt see any of these issues at all! Maybe you got a bad one???

Make sure your navigation gestures start from the black bezel of the Vaio then onto the touchscreen. You can use the calibration tool, change pen and touch settings, and change double clicking of objects to single tap to make the experience better. I'm not sure if the registry change to make touch more responsive for surface rt applies to your Intel tablet.
I'm with @vinscuzzy on this one... generally speaking I detest Sony products, but this sounds like a defective unit more than anything else. I'm not sure what you mean by "calibration doesn't work as well" (grammar, people: it conveys meaning). but if you can't fix this yourself, I would definitely suggest you take it back to wherever you got it.
When i use the calibration settings whenever i try to touch the cross it shows the input to be slightly on the right. i can't even close apps or use the multitasking. Closing tabs is hard or even clicking on links on google isn't accurate at all.
I bought this machine overseas and it isn't even out in my country so replacing it is too much of a hassle.
I almost considered it. But found there is a problem with the drivers, especially with Photoshop supposedly MS and Sony are using a specific driver but its not compatible with certain apps that use a different format of driver like Photoshop for touch.
The driver developers as far as I'm aware via googling don't seem interested in fixing this issue due to cost and/or it being niche market. Maybe try other software, I hope you don't have faulty system

Good evening, can you help me? Every time I go to use the multi touch on some touch to the game, it still works, just can not use the multi touch simultaneously, For example when I try to walk and jump in a game, the character jumps, but stop the run, in photos I can use the multi touch quietly, does anyone know how to fix this?Another problem is that when I go into the play store, type a name of any app and if it appears a direct link to google play store simply crash. I'm using lollipop 5.1.1 please help me

Is this a new problem on your phone?
Maybe a factory reset would help?
After replacement screen i believe, the problem of when I use the multi-touch and when I drop a finger both sort out, if I push a button and push each other and hold works, but if I let go of the buttons the two "disconnect" for example : if I run and shoot in a game, if I walk and pressing the shoot, he will ride and shoot normally, but if I try to get going and pressing 1 for 1 second to shoot, ride the will "lose the contact"
I've started to get a similar issue. I have developed a 'dead zone' in the top 3rd immediately above the centre of the screen. When scrolling the phone is registering a press on the screen and selecting links/icons instead of scrolling past them. Sometimes the phone goes loopy registering continuous presses along this line not allowing any other screen presses to be registered. I have enabled 'show pointer touches' in developer mode which shows the screen registering touches that I have not performed. Pressing the power button and then squeezing the sides of the phone resolves this temporally leaving me with the 'dead zone'.
Am I right in thinking that a replacement screen is needed?
