Due to damage done to the LCD of my S II I had to replace it. So I did that and I noticed two very serious issues. The first being the unresponsive touch buttons to the bottom right and left of the device. They were also not illuminated, there was also no evidence to suggest they were not connected correctly.
The second issues and by far the biggest is the unresponsiveness of the touch screen. When I enter my pin the first touch takes a few seconds to respond, then it proceeds to work as normal until the phone is unlocked. From that point whenever I try doing anything it behaves erratically. For example when I dial out it is painfully slow to respond to the inputs given to the touch screen.
Is there are way to address these issues and remedy them if so how could this be done.
Looks like a bad piece of hardware. Did you get the spare part from a trustworthy store? About the softkeys, you could check if the connector is connected correctly. As a workaround, you could use onscreen buttons.

Dropped my Thunderbolt but was able to get a replacement screen and get it installed. It worked correctly for a couple of days, but now the touch screen is not always accepting input correctly (sometimes). Middle section of the screen seems to split and act like it is getting multi touch input. Example is pressing the letter 'n' will enter 'b' and 'm' at the same time.
Other times the screen is acting like it is receiving touch input with nothing touching it. Texting or internet browsing is a major pain now, although everything else seems to work just fine. I have verified the ribbon cables are seated correctly and that there is nothing shorting out the sensors between the touch screen and the lcd.
Should I bite the bullet and replace the phone or are there other options for resolving this issue?
Most likely it's a bad digitizer. Get a replacement for your replacement, any decent shop should have a warranty. If you did it yourself contact your seller and get it replaced.
Having a problem with ALL keyboards (swift, flext9, stock) when tying to type letters on the bottom row (z,x,c,v,b n,m). When trying to input these letters the phone will input the letters directly above. I've read it can be a software or hardware issue. I have pulled the battery, wiped cache, wiped dalvik cache, and ran a superwipe. I was going to try and clear data for the stock keyboard (htc_ime) but cannot find it under Application-Manage application-All. I also tried looking under Application-Manage application-Running; what I found was Touch Input but no options to clear anything. Where is the htc_ime found?
I also noticed when in the dialer that I cannot input *, 0, #. Instead when I press these keys it will input 7, 8, 9, the keys directly above.
I am slowly beginning to believe this is hardware related, but what is weird is that yesterday after wiping cache/dalvik the keyboard worked normally. However, after some time passed, it reverted back to having issues again.
Is there anything else I can try? Could it be possible that the ribbon for the digitizer is loose rather than the digitizer just failing?
Maybe something you did mest up your Calibration you can check by going to.
"Settings ---> Language&Keyboard ---> Touch Input ---> Text Input ---> Calibration tool."
And see if that fixes your problem.
Seems to be known HTC problem for years and they haven't fixed it.
install a free app called 'Draw' from the Play store. When you open it the screen turns black and then slide your finger around and it will leave a line. This will show you if all areas of the digitizer are working. Press your options button to get the menu.
On mine Evo3d the problem started with it randomly starting to start programs or even make a few calls. I now figure that is from the digitizer acting up and behaving as if there was touches in the problem area which happens to cover the stripe of screen about from 1 to 2cm up from the bottom. 0 to 1cm is ok, then 1 to 2cm is bad, then the rest of the screen is ok. What has happened over time is that section of screen no longer seems to trigger phantom touch behavior but it does not register horizontal movement. On the Draw program vertical lines draw fine, horizontal ones leave nothing. Lines drawn at an angle skip and leave vertical lines across the defective area. Unlocking the phone with the Sense ring became almost impossible and I missed numerous calls. Even now that I switched to the slider unlock it is almost all in the bad zone and I have occasional problems getting the phone unlocked.
References are phone held vertical.
The problem originally happened on the stock rom, rooted. I figured it was a software thing so wiped the phone and took the opportunity to install LeeDroid. The problem still exists.
Using the calibration tool or any of several other suggestions does nothing.
Oddly touching keys works for typing and even SlideIT keyboard works though the line it leaves jumps around like crazy. I can't play some games that require that area of the screen. On programs that allow rotating I can usually get it to work as this moves the problem to a different area.
I really don't like friends with iPhones and other brands laughing at my phone.
I started searching Google and there are a LOT of other complaints going back several years and on numerous models, but no real solution. I am disappointed that the response from HTC seems to be that failures are within what they consider acceptable because the solution seems to be return the phone as it is a hardware failure though they do not admit to it. Some people report having the problem within a week on a phone that they left completely stock to see if it really was a user software thing. Some have had the replacement phones quit within a short time as well which makes you wonder if they even replace the digitizer when they recondition them. The actual complaint probably never makes it to the tech so if it works good for 10 seconds out it goes.
I am not very happy with the 'return it' solution since I have a $25 Zagg protector on the screen I will lose and it takes time to set up a new phone, and from the sounds of things the replacement isn't a guaranteed fix. Finding out that it is a known quality control issue that is still present after numerous years has soured me on HTC. If it was a rare occurrence I could understand but not when I read so many reports.
My last flip phone was indestructible and from Samsung. After all the hassles with crappy charge connectors and keyboard contacts from dust at work on a Motorola flip it was a true pleasure. I intend my next phone will be Samsung.

@mugsaway
when you need to type those keys in the dialer try turning your phone sideways as the dialer should rotate.
{ Disclaimer: the following text is my view about this problem. I'm not in any way responsible for any damage }
As there is very little info known about this phenomena I will try to explain it. I learned a lot of disassembly guides and by visualizing it (settings-development-show touches)
Ghost touch is a strange phenomena of various types and is due to a hardware fault between the mainboard connector and digitizer screen, I'm therefore trying to clarify it by categorizing them in three groups:
1. Small; Screen is unresponsive. 1 lock/unlock and it works again. Almost perfect. No need to replace screen. Most common.
2. Large; Same as 1, and often up to 5 touches and the touches are often moving/pressing parts of the screen. This can become a very frustrating period. Messaging apps and settings can be messed up by these touches. Often a lock/unlock will fix this temporary. A full screen replacement is recommended
3. Unworkable; Same as 2, and the lower and upper part are not working anymore. Notfications bar can not be pulled down anymore, typing become a nuisance and it not possible anymore and you curse your phone. Also it is not even possible to insert your pin, unlock your phone etcetera. This problem will not be fixed by a restart/reset or lock/unlock. A full screen replacement is essential.
Many people say this can be fixed by software settings, however this is a hardware fault. I tried many different roms and I encountered at all of them. The only fix that can be done to fix this is replacing of the full screen as it is not possible to apply/remove your digitizer.
For a long time I thought it was due to the degrading digitizer or something, in fact it is probably the connection between the and the mainboard. The screen has two digitizers: One for the touchscreen and one for the home/settings/back/search buttons. For some reason this last one did not cause any trouble. The first one has a flex cable from the upper part of the screen leading toward a small hole and heading to the mainboard. The problem will probably reside in the part between the digitizer and the small hole. Here, just above the screen, the flex cable is folded 180 degrees. This fold will cause the problem as it is very sensitive. Mine has a very small damaged part, the copper parts are visible. The cause of this is due to the rubbing of the bezel just under the speaker.
How to fix it?
Buy a new screen including digitizer (often HTC & Sprint branded) and make sure you protect this part as much as you can.
EDIT:
I re-inserted my old LCD display with a bit of tape around the damaged part. Since then I haven't had any ghost touches.
Mine was ghost touching so bad it was completely unusable for a few days. I was thiiiiiiis close to buying a new phone, then one day it just stopped and hasn't done it again since. Very strange. Anyhow, I will be replacing it with an s4 when the price comes down to $100 for us SERO users.
Ghost touch
Nice explanation, and nice 3 lvl sorting but, tell me one thing... I have experience with lvl 1 and 2 (two different phones) and for both of them simple ROM change / reinstall helped to solve this problem.
For ex. I had JB [ROOTBOX] ROM since the last week.. ghost touch problems were getting worse and worse with each new day yet lock/unlock still worked quite well.
I decided to test new JB MIUI ROM and like a magic touch my ghost friend is gone since than, but I am afraid he will return more powerfull than ever... oops that is a different story. However my phone is now working fine ... no ghosts detected.
So please don't tell me that this problem is only mechanical problem ( due to ROM change / reinstall worked multiple times). Actually I am pretty sure that is software problem which is supported by hardware hitches.
My friends "ghost story" is pretty similar.. but he reinstalled back original ICS ROM.
PS: I don't want to start flame war with this reply. It is just mix of my experience and opinions.
The digitizer on my HTC One X+ seems to be unresponsive on some strips of the screen.
This problem occurred after I replaced the lcd+digitizer module because the original one was cracked.
First 1 strip of the digitizer didn't work but 1 week later there were 3 unresponsive strips.
Today I reopened the phone to check if the new screen was the problem but after putting the old cracked screen back, it showed the same unresponsiveness but on different strips. I added a screenshot of a draw test in the attachment (since I can't post images from outside links).
On this screenshot, all 5 strips of the bottom half of the screen are unresponsive but sometimes only 2 or 3 strips don't work.
I notice that the screen freezes sometimes while trying to unlock the phone (which is a pain currently). Also the phone gets really slow and sometimes it randomly registers touch all over screen while I don't even hold it.
So my question: Is this a hardware or software problem? and does anyone have an idea how to fix this?
On the side, another problem: when I try to update the phone's firmware I get a notification that a new update is available (this is a very old update from months ago) but when I try to update it, the phone reboots, tries to install the software and then a red question mark appears on the screen. I haven't been able to update the phone for about 4 months now. Don't know if that has anything to do with my current problem but I thought maybe I should mention it.
Thanks in advance.
This may be because of the bad connection between mainboard and the touch module.
If you can , pull apart your phone and check the cable that connects the digitizer. Also, clean out cable's jack and cable's fingers.
As i am new, i cannot post imgs/ links.Search on youtube for "one x screen/ digitizer replacement" and follow step by step instructions.
Hello! So my Xperia Mini pro has been broken, it doesn't show any image anymore, I think there is a problem with the screen but I want a confirmation or recommendation to find out what the problem is.
First the screen "touch" capability stopped working, and then two weeks after that, the back and option buttons stopped working too. And a week after that ,there was like a screen "flickering" (I tried to recreate the problem in the attached image) when I tried to either open or close the slider.
Finally the screen stopped working anymore. I tried to connect the phone to the PC but says that windows cannot recognize the hardware. And there's one more thing: I can turn on the phone, it vibrates, but the keyboard lights seems that are not working, they are permanently off.. and when I try to Increase the volume it doesn't sound either... There is only the black screen and a backlight.
Please Help me to find out what is the problem, I'm thinking to buy a screen replacement on eBay, but some people told me that is the "flex" cable. I'm not sure if there is a fix for my phone's problem.
Thanks!
Hey there.
Based on my experience, yes, your problem is most likey a flex ribbon issue. Your flex has been ripping apart lately, causing many of its wires to break. This can cause a lot of unpredictable problems, such as a misbeheaving notification LED, inactive ambient light sensor, or "dead" display/touch digitizer. Your problems have gotten worse over time, which is clearly a symptom of a broken flex.
You phone is no longer booting up to android because the kernel no longer detects a proper "response" from the display driver and halts the bootup. This is why you can feel the phone vibrating when pressing the power button, but nothing else happens. Your screen assembly is fine, I can assure you that, unless your glass is broken, of course.
Here's one hell of a good teardown guide: http://www.ifixit.com/Teardown/Sony+Ericsson+Xperia+Mini+Pro+SK17i+Teardown/7275
I used that very same guide when I repaired my own xmp. I regret messing with my screen assembly because I destroyed it and had to buy a new one, which is costly
Thank You so much for the advice ! Now I'll try to repair it, It doesn't seem too difficult. Thank You Again!!!
