Touchscreen goes crazy at random times - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hi guys,
So I had to replace my broken screen.
I replaced and everything was working fine until one day, after 1 month, I start getting some ghost touchs in my screen.
There are some spots that triggers the touch at random times and keep pressed.
I've attached a screenshot showing one touch, that of course it is not mine, but keeps pressed for some reason.
If I press that region very hard sometimes the ghost touch disappear which leads to conclude that something is wrong with the screen that I bought, BUT if I reboot the phone it also fixes it, and that is what bothers me the most, I think it is not a physical problem but a software thing.
Can anyone help me break down this problem?

solution?
Do you had any solution for that?
Was it a hardware or software problem?
Best regards,

Problem with the touch screen.

I bought my HTC tytn II about a week ago and I am having a problem with the touch screen. Sometimes when I touch for example on the start or on the ok button with the stylus it doesn’t respond from the first time and I must touch again to respond. I have align the screen so that’s not the problem because most of the time it works ok. Can someone please help me with this? Thanks.
Sometimes the corners just need a firmer press where the digitizer layer is held more firmly. So you would need to check whether yours really needs two presses or just a firmer one.

The problem is not just the corners but the whole screen. Sometimes it just doesn’t respond from the first touch.
After further usage of the device I think it’s not the touch screen that has the problem because when it’s not responding it freezes for about 2-4 sec. and then it’s normal again. Is anyone experiencing this strange behavior? What can it be wrong it drives me crazy! Can please someone help?
My ATT Tilt is doing the same thing. Right now im running the stock ATT Rom with the ATT autoload crap disabled after a clean hard reset.
I notice that when my touch screen stops responding so do the soft keys and function buttons. The device appears to hang-up and **** the bed every once in a while. Its often enough to also drive me crazy as well.

Problem - no display on my Xperia

I have lost my display on my Xperia phone.
The back light comes on -- but that is it -- NOTHING else.
Has anyone else experienced this and more importantly - fixed it ???
if so, what did you do
What have you tried to fix it? I'd say something like this goes in order;
1. Soft Reset (since you don't have a display, use the reset button next to the battery)
2. Hard Reset (hold both hard buttons while pushing the reset button with the stylus)
3. Call someone, either your carrier or SE.
I have the same issue.
About 2 weeks ago issue started.
Waking from sleep or turning on, backlight lights up, but screen is blank.
This is starting to happen more frequently. Sometimes it will work normally, but more and more it is just staying blank.
Also during normal use, screen will become "garbled." Random bits of the screen move around to other parts.
Even during these problems the phone is functioning normally, can even push the buttons on the touch screen even though they are not being displayed.
I have an x1i, hard-spl. Was previously flashed with TouchX 10.1. When issue started happening, I flashed with a newer itje WM6.5 ROM. Same problem.
Issue of screen being blank also happens when booting to the tri-colour screen.
Any ideas?
I had the same issue screen just refused to display. I sent it back to Sony E for repair. They repaired and returned within 7 days. On the repair bill they stated it was a loose connection.
Interesting, hopefully that's it.
Out of curiousity, what was the repair worth?
Just wondering how much i'm up for if that is the case and I send it back.

Yeah.. I know this topic is pretty old, but I exactly have the same problem..
I have the Xperia X1 or about 1 year and a half now, everything was working fine until 2 days ago:
1. If someone calls me or I call them, they don't hear me, but I DO hear them
2. Screen responds, but remains blank (backlight only turns on)
3. Screen shows once in a while, but it pixelates.
I'm thinking of a hardware problem here, anyone knows more about this?
- Tried rebooting > no effect
- Tried soft reset > no effect
In most of all above problems it would be becouse of damaged lcd flex cable. It's not cost too much but you will have to disassemble phone and change it. http://cgi.ebay.co.uk/for-Sony-Eric...ries_MobilePhoneBatteries?hash=item563a472301

Screen alignment problem

Hi all,
I recently bought a used X1, wich already had a custom OS (Christian's) installed.
It's an excellent device, though there is one thing that really pisses me off.
The screen alignment is off all the time. No matter how often i re-align, after a short while it always is a few milimeters of, especially on the top half of the screen. So, for example if i want to press a button, i have to press above or under it, else it doesn't work.
I already tried cleaning the edges of the screen, even with pressurized air. Didn't help though.
Is there any solution for this or have i just been ripped off by the seller of this device?
Btw, excuse my english .
Can anyone help me please?
I mean, i really love this phone. But the touchscreen issue makes it kinda useless to me.
Is there any fix for it or is it just the way it is untill i replace the screen?
Hard reset. Or re install the ROM
Make sure to take your time while aligning your device, get some very precise points in or it will throw it all off. If all else fails you can try re-installing, but that probably isn't the problem if realigning fails. Possibly a screen issue?
I hard-resetted (?) and reinstalled the os, didn't work though.
When i re-allign it's all ok, but if i go to 'notes' then, and draw a little, it quickly becomes mis-alligned again.
The line is sometimes drawn more then a centimeter below the stylus :S .
I assume this is not a software problem, perhaps the screen is broken?
Anyway, i'm selling it back to the previous owner...
when i had a problem similar to this it was my ribbon cable that had worn away with sliding the keyboard in and out.

[Q] LG P990 Touch screen stops working until reboot

Hi everyone, I was hoping I could get some help with my LG P990 (Optimus 2x), I recently changed the screen and digitizer (it was broken so I replaced it myself with a new original one).
The thing is that since then sometimes the digitizer just stops working. The screen works, the buttons (screen lock and volume up and down) works, but the touch screen is dead. Obviously I can't reboot the phone so I take off the battery and put it back, the phone shuts down, reiniciates and there it goes, everything is good again, working perfectly... until it stops and the whole thing goes like this over and over...
Any clues of what might be causing this? I think it should be something software related since the digitizer works PERFECTLY until it kinda freezes... but I'm not sure, really not a smartphone guy so...
Thanks a lot!
P.S.: Tried to use the developer tools > locate pointer function and touched everything everywhere accross the screen and it's fully working, no dead zones, so the problem is "random" i mean it just stops working randomly, and I also didn't notice any patterns like "it freezes when i'm doing something specifically" it's totally random, happened when receiving a call, when making a call, while playing a game, while just browsing through the menu, while trying to unlock the screen... at least APPARENTLY random, maybe something i didn't notice if I do, i'll add later...

I have EXACTLY the same problem. Did you fixed it?

Out of pocket unresponsive touch screen

If I get a call while the phone is in my pocket, the touch screen is unresponsive.
The screen will become responsive again if I press the power button (causing me to ignore the call).
I've been having this issue with the phone for a long time now (ever since I bought it, I think), and I know now that this phone is not the only one to suffer from this issue but haven't found any solution.
I know for a fact that it is not related to defective screen or "problematic" screen protector.
Has anyone suffered from the same bug, and if so did you find a solution ?
