Ok so my touchscreen has been acting up as of a few minutes ago. Its starting to only work when the keyboard opens. So i thought hey maybe its just a software issue with the xm-7 rom, but then when i went to clockworkmod recovery, the trackpad doesnt work at all, not even when clicked. I've been treating this phone very well, even the condition looks nearly brand new, so what could have happened?
edit: my touchscreen somehow works again, but my trackpad no longer works. It has no function at all in clockworkmod recovery (no scrolling or clicking). When in the android UI, the trackpad only works to wake up the phone, the scrolling does not work at all. This is very strange and i cant tell whether this is a softwar or hardware issue.
I had this issue right before my slide died. Probably the ribbon cable. All of my front buttons stopped working entirely, the only thing that did work was trackpad scrolling. Eventually the screen went out as well. It might be just partially disconnecting somewhere, only enough to where the digitizer and trackpad sensor are being affected. That's the only thing I can think of. If it doesn't work in recovery, definitely a hardware issue.
Thanks, I figured it was a hardware issue. I'm gonna take the phone apart and see what I can do since my 1 yr warranty with this phone is up.

Hey guys,
I have some weird issues with my XS and I don't know whether they are caused by software or hardware. Here's what bothers me:
Every time I connect something to my XS like the usb cable to charge it or transfer files, an hdmi cable or even headphones my phone gets totally unresponsive. The touch buttons respond after about the tenth press and even the screen is unresponsive as hell. If I scroll through the app drawer for example, my swipe gestures are often recognized as a press so that apps are launched although I made a fluid swipe gesture. On the other hand pressing on a screen to launch some app sometimes isn't recognized at all. If I plug out the whatever cable, everything's okay again.
So, what do you think? Is this a hardware or a software issue and what should I do now?
Some background information: I already tried a factory reset and such things. My phone software is stock ics (see signature).
Regards

Hmm i havent experienced that before. Try updating to .50 stock and see if it is still there. If it is try and roll back to gingerbread. This will tell you for sure if it is sofware or hardware.
I'll try that but if you say that you never experienced that before, hardware would be more suspicious.

Many people experienced this, i still have it.
They said its a touchscreen fault or something and its needs to get replaced by sony.

Are you planning to send it in? I mean I hate this bug and it bothers me a lot, but giving away my lovely phone for a while seems a bit cruel
Can I send it directly to Sony or do I have to send it back to my vendor (amazon)?

Guys I have the same problem. When connected to the official charger and USB cable the problem is minimal. However with a car charger or an auc jack/headphone the touchscreen is unusable.

Re: Touch screen problem with Xperia S (LT26i) [ICS Problem?]
Hey diyotama,
The guys at Meteor Ireland that sold me the phone are sending it to Sony for repair today.
Thanks,
sobanek
PS. They've identified the problem as a battery problem (something with voltage) that's why when anything was plugged into the phone, the touch screen would lag - because it didn't have enough voltage for the touch screen, and therefore, it wouldn't recognise all my touches.
The problem is I've unlocked bootloader and flashed some roms, lately very satisfied with Slimbean. However there are some issues with flashing and warranties.
I wonder if sending in my phone for repairs would be wise. So I would like your advise.
Is the cause a battery related problem? Is this ROM related?
Send in the device or live with the results of flashing?
I still dislike this issue but I can live with it now.. I noticed that my touchscreen bugs mostly in the lower parts of the display. So I installed some framwork mods that allow to use my phone upside down (rotated 180° and onscreen buttons enabled). So in the end its not a big deal for me anymore because the most touches are performed in the lower section of the screen.
I also unlocked my bootloader lately. If you want to send you phone in you can relock it but maybe they find out what you've done. But in my opinion this is a clear hardware issue which hast nothing to do with unlocking or flashing. So I think they can't say that this is your fault.. Regarding the voltage theory: interesting theory but I don't think this is true.. As I said: my touchscreen works perfectly in the upper part while charging but not in the lower..
I had issues like this when I used a different charger.
Yeah thats right.. I found out that the original Sony charger delivers 1500 mA.. If my phone is connected to this charger, the effect is at least noticable.. But when I connect my phone to my 800 mA car charger, the phone feels absolutely unusable..
wut... I got tired of using a screen protector, so I took it off. Immediately I noticed the screen became unresponsive at times, and discovered it was the bottom part that was unresponsive (as @mister-g1 wrote). But it only happened when the charger or aux was connected . And then I re-applied the screen protector and the problem was completely gone! I can reproduce this in real time with the app "touch test" and record it if anyone is interested.
So it looks like I need to buy some new screen protectors..
Also, did anyone send their phone in for repair and got it fixed?
When the screen protector is altered, you must change it. Regarding that other problem, well...always use original chargers, headphones...etc. If along the way you did otherwise, well, that's the source of your problem. My advise is that from now on you must use only original chargers/headphones/etc and your phone will adapt back, it may take a while but it will do it.
TIP : Try plugging in the headphones while the screen is off. See what happens when you turn it on.
Best of luck.

I should be able to use it without screen protector.. Anyway I bought 6x screen protectors, so I have enough for a while The problem occurs with original charger and headphones, and when I plug it in when the screen is off. And even though I have used my N7 charger, that should not be a problem.

Same here.. I always used the original charger and the problem was always present.. And using another charger shouldn't be a big deal.. Thats definately a hardware issue.. Think of the yellow tint screens and so on.. Sony does not always deliver the best screens.. The Xperia SP has similar problems like shown in this video:

Hello,
I just got my N7 back from repair where they replaced the ME571K SUB_BD./AS board since the USB Port was not working anymore.
Luckily the port works now, but on the other hand the Touchscreen is not responding at all.
I tried restarting already without success. I also cannot reset the tablet since I got TeamWinRecovery Touch (and CWM 10.2) installed.
I can connect the tablet in bootloader and with "fastboot devices" it shows up as 077a744a.
Could anyone help me on how to flash or reset the tablet?
Ps.: This replacement was out of warranty, therefore I paid for it. The service center suggested replacing the mainboard (to make money) as well. Before I sent the tablet in everything was working just fine except mentioned USB Port.

I just flashed (with wipe) the factory image without success.
There's no response at all. Also when I try to get into recovery mode now the opened Android with the red exclamation mark shows up.
Is there a low level touchscreen calibration or something I could run through fastboot?
Anymore help would be greatly appreciated.
I'm starting to think they just put my motherboard in another tablet with abroken display...
I'd return it, it sounds like total screen failure.

That fallen android is just an image overlaid over the stock recovery menu. It just means you've booted into stock recovery. You can get the recovery menu by press/hold Power, press/release VolUp, release Power.

There are various different touchscreen software you can load via fastboot and there is a calibration file in /system/usr/idc, but it isn't clear any of these would help if your screen doesn't work at all.
You can try changing the touchscreen software, worse case, it stays the same:
http://forum.xda-developers.com/showthread.php?t=2428133
Alternatively, you can open up your tablet and check to see if the flex cable for the touchscreen has become dislodged. There are 2 cables that run across the center battery. The one that is reinforced using tape is the one for the touchscreen.
Just did a reset but it didn't work.
I already tried these different firmwares from your link but it didn't make a difference.
I guess the screen is just broken. Or is it possible that the new Subboard is not working with the motherboard and therefore the screen fails?
I opened the back but it looks fine doesn't it? Is the big cable the on for the touchscreen or the orange one?

Yes, that is the cable. You can carefully removing the tape reinforcing the motherboard side of the orange cable and seeing if there is anything preventing a good connection, possibly use compressed air to clear out the connection area. The other end of the orange cable also connects to the touchscreen underneath the usb module so you would need to remove some screws to check that connection.
That's about all I can suggest. It didn't sound like a software issue because your screen completely doesn't work.
Yes I will look at the side where I have to open screws since that is the part they changed. Mabybe they didn't connect the screen.
I also wrote the support already.
Thanks for your help, I will report back.

Hi there
I have also experienced a very similar problem. The charging port on my 2013 Nexus failed to work, I then ordered a replacement part and changed it. It is very straight forward and simple to do for a novice like me.
on replacing the pcb the charging resumed faultlessly but the touchscreen has become unresponsive, i then replaced the old pcb and the screen has resumed functionality, but charging is not working.
The part was replaced by the supplier and it has occurred again, charges fine but the screen is unresponsive. Again i reinstall the old part and hey presto screen is ok.
I am now going to try and replace the actual usb pin itself from the original failed board and see if i can repair myself.
I had also done all the resets and reboots mentioned online.
Not sure if this helps but thought i'd share as its relevant
Many thanks
Is this the n7 2013? If it is how the hell did you get the back off? I tried and was afraid of breaking something.
Sent from my Nexus 7 using xda app-developers app
It's really easy. No tools required. Run your fingernail around the perimeter of the tablet edge between the screen edge and angled plastic. You'll hear the clips releasing as you go. Then carefully work the back off. No glue, just clips. Takes about 1 minute.

Any update on how you solved this ?
I would appreciate if anyone could share the solution for unresponsive touch screen, if it's possible at all. The screen only reacts on the edges, and only to the swipe gestures, not to tapping. But all and all is the same - broken USB, replacement part, unresponsive screen.

Is there nothing to "calibrate" the screen? Asus is supposed to do it for you.
I think the problem is the rev. number of the usb board.
I found this explicative video on youtube, but I can't put the link. Look for "Nexus 7 2013 2nd gen charge port replacement issue"
I have the opposite problem: I changed lcd and digitizer two times, both times touch screen was completely unresponsive. I wonder if there's a software solution for this. I know usb board have different revisions, but what about digitizers? Are all the same for every nexus 2013 model? In this case I have to think touch screen connectors on usb board are broken somehow...

I know this is an old thread, but the problem is replacing a rev 1.3 board with a rev 1.4 board. They are not compatible touch screen wise. I have heard that there is a reset tool that only Asus has that can fix this...

My kid broke the original screen and I replaced it with a cheaper one that worked great until he broke it again
Got a new screen but the touch doesn't work and I can't enter twrp except if I disconnect one of the daughther board connector ribbons (can't remember which one now).
My guess is that the screen is for a different revision board.
Any way to solve the problem?
This is the perfect thread. I have a collection of Frankenstein parts and the problem I've had with 5 or 5 devices (flo) is the sub board. Some work, some don't. I'll try the firmware links and report back.
Has any one found solution for this problem, even my Nexus 7 2013 touch screen has stopped working after I repaired the micro USB port. Actually my tablet was not charging and I figured out that there was some lose contact in the micro USB solder joints, untill then my touch working. I haven't changed any daughter USB board but just resoldered the micro USB port after which my charging has started working and I can even connect a mouse or pendrive through USB OTG cable but the touch screen has stopped working.
After using my Pixel daily for 6 months (got the first batch, pre December 25th) and having next to no issues with it (wifi strength sucks, even with Xceed kernel, but it's better than it was), half of my screen decided it wanted to go goofy. I was using it two days ago and everything was working fine, I used it yesterday morning for a few minutes and then plugged it into the Google charger that came with it and let it sit on my couch for a few hours while it was charging. I got on the bus, and pressed the power button to wake the screen and nothing happened. Thinking I had it turned off I held the power button for a few second, and still nothing. So I held it for 30 seconds and when it brought up the bootloader warning the right side of the screen was glitching, same thing happened on the Google logo, boot animation, and continued into Android. I powered it off, hoping it would go away but it didn't. The slight glitch then turned into static "snow" which will then change sporadically based on what I'm doing on the tablet. That area of the screen still works perfectly because touch input works, and when I take a screenshot and view that area of the screen it shows up just as it should. It seems like there is an overlay on the right side of the screen that won't go away. Since it happens from the moment you turn it on makes me think it's a hardware issue but the fact that the screen itself still works perfectly makes me think it's a software issue. I haven't flashed the stock ROM back on it yet or locked it backup yet since I don't have a type c to type a adapter with me, it's still under warranty but I wanted to see if you guys could help me fix it before I sent it back.
TL; DR
This just started happening to me today, exactly as you described.
Interesting. I just RMA'd mine, should be receiving it within the next few days.
I'm returning mine too. I've determined that it's hardware because when I applied pressure around the edges of the screen I felt something slightly pop into place and then the problem was temporarily corrected. If I apply slight pressure to parts of the screen it happens again.
At this point I've flashed back to stock and I'm in an eternal recovery bootloop that I can't fix because acquiring USB drivers that work is incomprehensively difficult.
Just had mine go as well :crying:
Oh wow, that sucks. At least I'm not the only one though. I just got my new one a few days ago and all is well so far, hopefully this one won't screw up. RMA process was very smooth.
As for the USB drivers I usually have to install them manually by using the "select driver from a list"

Add me to the list. Just went through the RMA process and am now waiting for the replacement to come. I can deal with the wifi issue and the random reboots, but having half of your screen corrupted is unacceptable. I don't even know how this is possible unless some genius at the pixel C team decided that it's cheaper to source half a screen and glue them together.
It's kinda crazy that I couldn't find this happen anywhere then all of the sudden it's happening to you guys! I'm extremely confused how it happened and what actually went wrong with it.

I don't believe so, I think it has more to do with the screen, since it would occasionally correct itself, and even when half the screen was screwed up, screenshots would come out perfectly. It's almost like there's something stuck over the right half of the screen.

Of course screenshots would come out perfectly. It's just a memory dump of the video RAM. This is a problem with getting that memory to the display. I think the display driver is part of the SoC. I could be wrong. Maybe it's a cable.
But it seems like a bit in the display driver is never getting enabled.

I'm fairly certain that it's a physical issue with the screen or the connection to the screen. When I had this issue I saw a visible change when I applied some light pressure around the edges of the screen. At one point it almost felt like something popped into place and the problem went away (then resumed.) Also, if I applied some pressure on the lagging side of the screen I would see some odd behavior as if the connection was fluctuating. I didn't squeeze hard, but it didn't take much.
I have had TWO Pixel Cs do this now. The first got the dreaded half screen of death after 5 months back in May, and the replacement that Google sent me has just started doing it today after just 3 months. The second device was from a much later batch than the first.
My experience so far makes me think that all Pixel Cs might have this hardware defect - it's just a matter of time before it happens. That's kinda gutting if it's true as for me this is the best tablet out there, and I can't see anything else coming close to replacing it.
About to contact Google for RMA again I guess. Third time lucky maybe...?
Wow really? That's no good!

According to this http://forum.xda-developers.com/pixel-c/general/mapping-problems-to-serial-t3274660 there still seem to be some issue with the #61250 batch so I'd try for a 3rd time to see if you get a 6202000 one (what i have now). It's stupidly frustrating but the Pixel C is too good to give up now.

Thanks for the info. Not sure I'll be able to determine what s/n Google sends me next time, but here's hoping I get a good one and that I've just been unlucky so far. I won't be able to RMA until I get home from vacation later in the week anyway. If they send me another Pixel C that develops the half screen problem down the line, I will surely have to get a refund and maybe go for a top end Chromebook (with Google Play of course) next time.
Does anybody know what could be the problem? Mi Mi6 was working fine till one day it fall on the back side from my pocket(it has a leather case - scratch marks). The touch was not working so I did reset it and it was working fine for another half hour then it stopped. I opened the phone because I tought it was a problem with some cable but everything was OK. I tried by squezing the touch and suddenly it worked again till today. I have tried everything but nothing works. Any suggestion?No water dmg etc.

Sounds like the touch sensor had separated from the LCD....
Honestly a permanent fix would be to replace the whole screen panel.
A temporary fix would still almost certainly ruin the screen and that would be to disassemble the whole phone and then try and repair the panel that's broken.
I'm not a hardware expert and I've never done more than battery replacements on phones so I can't say more.
Someone might give you a better idea here but I would personally have it repaired by Xiaomi with an official display replacement because that way you get an official replacement.
Such a shame for the drop
Jerry Rig everything does a tear down on YouTube of the Mi 6 so you should check that out for a basic idea of disassembly and repairs etc.
There's lots of good guides
Thx. Ordered new lcd and now works.
