Z1 Touchscreen Issues

Does anyone have issues with the touchscreen skipping every once in a while? Occasionally, there is an area on the lower half of the screen that seems to be insensitive, but if you start touching around it, it goes back to normal.
I've discussed this with some fellow Z1 owners and it appears to be a relatively common issue. There is some discussion that it may be due to overheating or a software issue.
Anyone else have this problem?

Had this once while my device overheated hard(~47-48°).
Not sure if I have to be concerned about that, because otherwise it works fine.

At first I thought it was an issue with crappy screen protectors. The Z1 already has a anti-crack film on the screen so I thought that adding a poorly made screen protector would create too much distance from my touch to the sensor. However, I've tried replacing the screen protector and also asked other people with varying brands of screen protectors and it seems that the issue still persists.
The issue seems to occur most often on the password screen for me (which is particularly annoying).

I've had it too, lower half of screen does not register slides on login screen for a brief moment.. No overheat!

No overheat here 2 but with the same issue.
Also the last days i think that all the screen sometimes is more insensitive than usual.I have to touch 2-3 times to do what i want.
I think that is a hardware issue.

Have it sometimes as well sadly! Can't figure out when exactly it's happening though..
I find it very annoying when I'm scrolling and at the bottom part of the screen, the scrolling becomes a click, which brings me to a place I did not intend to go to. Hope it's software, but can't imagine that.

Happens to me as well, regardless of device temperature. Based on the seemingly random nature of the issue, it should be a simple fix via software update. A similar bug persisted on the 2013 Nexus 7 devices when you laid them flat on a surface.

Same problem here!!!
I think is a hardware issue. When you touch the alu frame the phone works fine. If the phone is on the table or in a cover the issue are immediately there.
Sorry for my bad english. Hope you understand

I noticed some small things and thought it was me but I guess this makes sense.
Could be worse, my previous Note 3 had multitouch issues and had problems register several fingers :silly:

Considering how common the issue appears to be, I find it hard to believe that this is a hardware issue.
I also don't believe it's related to overheating since it seems to happen even when I haven't used the phone at all for a long time.
It feels like a software issue to me since the issue sends to go away if you touch another section of your screen

When you touch the alu frame the issue is not there. Only when you use phone without touching the frame.
Must be some kind of hardware issue...

I am having the exact same issue. The weird thing is, is that it doesn't always fail to register my finger. I've gone a few days without it, then suddenly it's back again. Also in the Xperia Diagnostics app I could then see the phone failing to register a proper line, then 20 seconds later it's gone. Weird thing indeed.

Is this the case? I don't think I've ever used my phone without touching the frame somehow.

Yes, I have it as well.. First of all though, to reply to a lot of people on this thread, it happens regardless of "flat surface, touching the frame, overheating", or anything else. It seems to be completely random with me. Sometimes everything is perfect, then it goes nuts for no apparent reason whatsoever. I'm almost sure it's a software issue, and hope sony will address this issue soon!

it also happens sometimes to me.
the only thing that helps is to touch the ground of the ac power socket. it seems like the screen needs much more potential difference between the pointer and the screen itself and after a while of using it the pointer (you and your fingers) are more loaded.
thats my theory to it.

Unfortunately, unlike the rooting camera bug, it doesn't sound like Sony has even acknowledge it at all.

Exactly this.

I often have to attempt inputting my password multiple times before I can finally get it right. I have since switched to PIN unlock. Really wish there was some sort of response from Sony.

I'd you're using pie then stop using it and retry the affected area. I had this issues because of the activation area causing certain keys on the keyboard to become non responsive.

Xperia X Performance (F8132) Accelerometer failure & Screen Auto-rotate irresponsive

Xperia X Performance (F8132) Accelerometer failure & Screen Auto-rotate irresponsive
Hi All,
I got an issue bothering me since I bought Xperia X Perfomance (F8132) Mid June.
The auto rotate function failed after a while but everything goes fine after reboot.
When it fails, I use "Xperia Service Menu" -> "Service Tests" -> "Accelerometer",
then all X,Y,Z are zero and the ball just sticks and freezes at mid.
I bought from Taiwan and I can find 15 more people having the same symptom with me on 2 forums
( http://mobile01.com and http://gamer.com.tw ).
Hence I don't think it's only me and it's a common issue or common yield problem for Xperia X Perfomance.
I post here because I'd like to find more people with the same issue and raise the attention of SONY in order to find the root cause (i guess it's either over-heat causes this or accelerometer yield issue) and give a patch.
Now I'm using a APP "Rotation Control" to workaround this, but all photos cannot records correct orientation data and no auto-rotate is kinda inconvenient.
For a flag-ship and high-priced cellphone for SONY this year, it is very disappointing to me. :crying:
Version: 35.0.A.1.227 and 35.0.A.1.238 both occur

I also have that problem. No more auto-rotation after a while (1-2 days) . Only a reboot fixes that

Thank you for letting us know.
It shows it's not a regional FW issue but a global HW or FW one.
I wonder if SONY knowing this. If not, we need to address this and push SONY to work it around.
And if it is not workaroundable, SONY will have a big problem.

I have the same issue on my Xperia X (F5121) bought in Sweden. Haven't checked the accelerometer but the behaviour is the same and reboot is only fix.

I have not had any problems with auto rotation, my accelerometer works fine but my touch screen is messed up

Can you specify "messed up"? I've had issues with the touch screen also, mostly that it registers a tap while I'm scrolling resulting in involuntary tapping on links. Also it often takes a while to start scrolling, as if the screen has a hard time recognising the swipe.

I have the same problem. The accelerometer stop working 15 minutes after reboot.
Help me verify if is caused by a third party app or not.
Use your phone in safe mode for a while.

I'm from Hong Kong, the accelerometer and its auto-rotation of my x performance has the same problem that it won't work until i reboot my phone.
I dont think that is caused by a app crashing when the problems occuring in all around the world.
The issue didnt come to me when I was not yet update to 35.0.A.1.282. Please notice this problem SONY. It seriously affected the satisfaction from user of the phone from your brand.

There is a topic on the Sony support forum - see here: http://talk.sonymobile.com/t5/Xperia-X-Performance/Accelerometer-stops-working/m-p/1158490#U1158490
At least they are aware of the problem. As soon as it happens again on my phone, I will send them my logs. I will report any development...

It seems that I uninstall the AR effects in my phone and reboot, it works again

Rotation fails
Hello guys,
I have the same problem. Yesterday it worked fine, but today, the auto rotate don't work. Very disappointing. Only a reboot can help but not every time.
Sony has to do something with it.

Gyroscope/Auto-Rotation Issue
Hey everyone,
I'm also having this same issue, but only since the most recent update from late September. When trying to make a pic display as fullscreen by rotating the phone, nothing happens, unless I reboot the phone. Then within day or two, it starts happening again. When I go to camera it loads up and STAYS in landscape mode, no matter what I do, even closing it out and clearing out the cache & force stopping it then reactivating it. It seems like a software issue that Sony needs to address PRONTO!
It appears another thread here on XDA is dealing with the same issue. I tried shenlong85's idea and it seems to have fixed the issue, but I need another day or so to make sure. If you don't hear from me by Sunday (10/23), assume it's been fixed. Hopefully the Nougat update we're all about to get any day now will permanently fix it!

The memory uninstall updates only prolong the issues. Seems like the firmware issue earlier on.
Nougat... When are u coming?

Well, we'll see. I am giving my XP 'til Sunday........if no more auto-rotate issues by then, then I will consider your idea to be gold. lol Of course, once we get Nougat, I'm hoping it will ensure that the issue never comes back period. As of this time, the issue has NOT returned.

I bought my Xperia X Performance from Kogan who sells imports in Australia from Asia and I have the exact same issues with my orientation and touchscreen. However my jumpy touchscreen only seems to occur while charging.

I tried shenlong85's idea, but less than 24 hours after trying it, I switched my phone from Portrait to Landscape to view a 16:9 widescreen pic I had in my Album, and it WOULD not auto-rotate the pic. So unfortunately this "trick" doesn't work either.
Just have to hope Sony includes a fix with the Nougat update we're about to get any day now from them.

I'm noticing now too that once the Auto-Rotate function stops working, so does Smart Call Handling. Have to swipe screen once again to take calls. Hurry up Nougat!! lol

I'm having the same issue and the only help I'm getting from Sony support is to factory reset my device :\ I'm hoping Nougat makes it's way to our devices soon. I really like this phone and this is a pretty big issue to have.

I agree Spencer. And yes Sony Mobile told me the same thing. I'll do a repair (which yes, includes a factory reset) only IF Nougat doesn't fix it. They say we're getting it "in or close to October", so I'm guessing it's gotta be coming any day now. Hopefully they include a fix with Nougat though and I don't have to do that. Getting tired of this BS with Sony. My Z3 had an issue where if I turned on Stamina Mode, it would 1) mess with my MMS (group/pic/video) text messages.........you don't know how many times I had to ask ppl to resend those to me and how much that sucked lol 2) Cause a "random" battery drain. Only fix was a factory reset. I FINALLY got wise and realized it was SM and kept it off. Found a great app called 360 Hibernation Master that did what SM was supposed to do but better, MINUS the buggy BS. But OF COURSE it doesn't work on any X series phone (at least not my XP), so I'm stuck with SM now. At least Sony Mobile FINALLY fixed that bug with SM so that's not an issue anymore. lol
It is a big issue, and it makes me not want to keep buying their phones.

Touch issues / Sensitivity issues after Nougat update

Okay so I wanted feedback regarding this whether someone else is experiencing this or not.
I have gradually observed during the last few days that a lot of my touches to click have gone unresponsive in Nougat. Initially it was something that I hadnt quite noticed but slowly the trend became obvious. Now dont get me wrong, this would happen a few times here and there with lollipop and MM as well, but the rate is far higher now on Nougat. Especially when typing on the keyboard this means mis-spelled words, missed letters, and accuracy is far worse now.
Has anyone else observed this or is it just me?

Just got my xcover 4 with nougat installed i have the same issue.
The sensitivity is low and i need to press a bit higher finger force to respond.
Even with sensitivity (glove mode) set to on things get worse.

I'm seeing the same thing. What is strange is that I'll see the button highlight/depress, but no action occurs. This is on multiple apps.

On what device/OS?

Sprint Note 5 on Nougat

Did you try gloves mode? Does it work?

the same for me on 920cd and the same iusse using S pen

I contacted samsung Greece about the existing problem.
I reported the problems me and you guys have and the tech support told me that your problems exist because you did not factory reset the devices before upgrading to nougat.

Anyone tried to contact samsung about the problem?
They dont know anything about it.

facing same issue screen lagging in note 5 sm-n920s also tried custom rom but still lagging in typing and scrolling on facebook

I have the same problem on my xcover 4 here!!
When I run the the touch screen test, touch screen responds well, but when I want to write a message or to scroll the home screen Its very annoying. It looks like software problem.
please help

Hi guys.
I have 2nd piece of Xcover 4 SM-G390F (first was change by seller for new one) and had the same problem. First 2-3 days all work perfect.. I have installed my applications, work perfect for two days, but after this... --After wake, display react only in centre area, 1 centimeter from display border no reaction or react on xxx touch. After few seconds (20-30) display react on full range, but with lags... So... I go for support to Samsung official at CZE.
Support tells me, that they don't know about this problem, that I'm 1st who has this problem... And some other bull... about unofficial sell and any other. So I post them IMEI and they let me know, if my distribution is official or not, and we'll see what next. They recomend me to go to service center, where somebody looks on my SM. So I see tomorrow.

P20 Pro: Random ghost movements after every restart?

After just having received the Android Pie 9.0 update yesterday, I still have the same issues as since I bought this phone:
Being that after a restart the phone is unusable, as it starts doing whatever it wants, as if there were shadow presses and swipes on the display.
These totally random, involuntary movements, as if I were touching the screen, even though I don't. Those occur so fast that I can only stop it (for a limited time) by pressing the power button (turning off the display and all actions), are totally not something I have ever experienced on another phone before, not even with OnePlus.
I took my case off just in case this would cause pressure on the phone, but it still happens without the case. I propped the phone up so that I definitely don't touch or cover any sensors, but it still happens.
It seems some internal sensor is broken, as this issue still persists after updating to Android 9.0. Unless this might be related to the Nova launcher?
Unfortunately I don't see a way of recording this issue without compromising my personal information, so I can only describe it.
I hope I can resolve this through a device swap through my carrier, but I doubt it. Has anyone else experienced this issue?

Is there a third-party one-button lock screen app installed on your phone? There may be conflicts.

No, there is no necessity for this.
In the fact issue occurs also in Safe Mode as well as after cleaning the system cache (wiped through the menu which is available for soft reset / wiping all data).
The issue got only more and more severe this week and sometimes temporarily froze the screen / inputs and did lead to error messages on the camera app, making it impossible to take photos temporarily.
Huawei referred me to a local repair shop and I will hand in the phone for repair by early next week, once I have organised a replacement phone.

I've changed screen and after sometimes phone goes crazy

Hi mates, I need you help and suggestons,
unfortunately my phone felt down and I needed to change screen, the service which installed it asked me to choose one of the available (chinese) screens I I select the most expensive one. In the beginning all was ok, but time by time (about 1,5months) the usage gests worst, when the screen start to be a bit dirty it start recognize touches anywhere (moslty in the up side of screen), itself does commands, it's not possible to do nothing. WHen this happens I need to keep press the power button for 10 seconds tille ht ephone reboots, after reboot all become regular.
My considerations:
1) it doesn't seams a defective screen or a bad assembly, because after reboot all is good, if there were such problems a simple reboot can't fix them.
2) it looks like an incompatibility between OS and the touchscreen firmware, and probably it's something Xiaomi does with intention to create problems for cloned spare parts. Maybe the OS is "instructing" the touch screen controller how much sensibility to use, how much it can be dirty, etc.etc? the protocol of the latest OS isn't at all compatible with the cloned device and it result on crash of functioning. A reboot solves the problem.
If that is right, will a ROM update to another OS (not IMOU, as I have now) can fix the problem? Or there is any app that can perform a touch screen reset? Or any other trick to solve my problem? Than you for answers

Hi mates I need help, with cold weather coming it got crazy as soon it feels cold. WHat can I do to solve problem?
Updating ROM to a non official can solve it? The display isn't broken! A reboot fixes always the problem..

It is not original screen from xiaomi vendors, just a oem part with lower quality (chinese sell it alot on aliexpress with many type amoled, oled and LCD panel too).
Ghost touch easy happen on oem screen no matter how expensive it is.

Thank you for your kind answer, this is a really big issue.. it's very annoying using the phone like that, I've noticed it suddelny starts when the phone is exposed to cold temperature: lowering the screen temperature quite suddenly means it goes crazy, when it's crazy the only way to fix the proble is reboot the phone, with reboot it calibrates again and works ok, till next event. MY question are:
1) Can I forse myself a calibration?
2) Does other ROMs, not MUI, manage and fix this problem? (using another touch driver may solve the problem, chances are MUI introduced updates and become more selective to work with only original displays, to disancurage the OEM parts, so using another ROM wuth an older driver may solve the problem)
3) If I buy and add a protective glass on display, does it behave better?
Your experience is essential for me, thank you for posting!

imo
1. you can not
2. Roml sorfware can not
3. Protective glass make lower touch experience.
- Not all oem part come with defect, some working fine, it is just random.
- To repair you need replace new one, or buy original screen for sure.

Thanks for answer, I do believe that the problem can be managed by drivers, "resettig" the touch chip wil correct the problem. Probably the defect is on the firmware of the touch panel, it gots errors from touch.. ok, but it doesn't understand it's just revealing mre and more ghost touches. These FW have the task to filter out the ghost,, maybe they don't do it well.
A second chance is the comuinication between this chip and the MUI OS, the connection goes broken by some mistakes, "unalligned" and MUI got any touch position from nothing.
I don't believe the screen is defective, because after reboot it works perfectly, thil the next strong environment conditions change..
What is Roml software?
