Problem after touchscreen replacement (original one) - HTC Sensation

Please help me with this touch screen problem:
In my HTC sensation 4G touchscreen has been replaced (together with display) and as a result I've noticed that device no longer registers fast swipes. No lag or other problems, just when you move finger fast - touchscreen fails to register it. In multitouch tests circle disappears during fast movements and in games like fruit ninja there is no line after the finger. Guys who helped me tried several digitizers they had in stock and all of them had this same problem.
My original digitizer and these ones are probably different models because mine was T-mobile and these have HTC written in the middle.
So I wanted to ask did somebody stumble upon this issue and is there a solution?
Or is it possible that all new ones they've tried are bad?

i have similar issue. my screen doesn't register any touch on the left half, unless i touch the right half a few times first...:/ my digitizer got changed as well. but after that all is fine...only after i turn off the screen, then on again.....it's a little annoying, but not making my device useless at least.
as for to what's the cause, possibly each phone needs a special digitzer...as for the solution, i tried many, nothing worked...

I read of someone with a similar problem, they took screen apart again and found the wire was slightly pinched, they said they carefully put wires back in place and paid extra Attention to the wires and problem was solved. Now, I personally have not tried it but I did read this fix. Maybe it might help, worth a try? Hope this helps!

I'm on the same boat. Dropped it and cracked the screen. So I bought a replacement screen and replaced it myself. Its the one with just the HTC in the middle. (I'm T-mobile) Well now, like yours, it sucks at registering touch accurately. I have to press solidly on the screen to swipe screens or to open apps. Texting sucks because i have to press on each letter good or else it picks the wrong letter. I've searched for a solution as many have had this issue but seems like they just returned it for a new one. I cant since i replaced the screen and voided my warranty. I have taken it apart twice and carefully reassembled it making sure everything is good and snug and in the right place.....Still no love....Sucks! If anyone can help, it would be much appreciated as i have hit a dead end with this issue. Thanks.

this is quite different problem. Sensitivity of my display is OK unless you move fast. In your case it seems to be the problem of this exact screen. Try downloading SGS Touchscreen Booster from Play Store and play with settings.

Display problem (broken??) - HTC support & warranty

Hello everybody,
I want to tell you what happened to my Touch Pro this evening:
On the display (also if the device is off) appeared a small rectangle in the center (about 2x3 cm) made from bubbles. Well, not bubbles, I’m quite sure that are liquid crystal. If I put pressure with the finger the “bubbles” move and follow the pressure also out form the edge of this small rectangle)
As I can reach a decent camera I’ll post some photos of this rectangle.
The strange thing is that the device didn’t fall in ground, didn’t have temperature range; nothing hit it and so on. It was in my pocket well safe!!
If display is on the problem is quite invisible, if display is "black" or off... ....Grrrr!!!
Now, my questions:
1) Warranty is also for display?
2) How warranty works in Italy? Where should I ship the item? Which times?
3) If I have ship the device, sould I load the original rom & radio? Where can I find the rom?
Certainly, first thing I’m going to do Monday morning Is to call Italy HTC’s support number…
Thanks a regards,
Andrea
The "oil spot" problem isn't a broken display. It's the touch sensitive layer, which has been subject to too much pressure (carrying it in your pants pocket, etc). This has been happening on a bunch of Touch Pros and Diamonds. You should still be able to use it just fine, but touch sensitivity may get worse over time.
HTC may or may not be willing to replace it for you (and if so, they may or may not charge some kind of fee). Although it's just a hardware change, you should probably recover stock SoftSPL for warranty.
I have the "oil patch" problem with my Touch Pro. Unfortunately when I first noticed, HTC would not fix it for me, so I still have the oil patch on my screen, although everything still works fine so far. If it gets worse, I plan on buying a replacement LCD/touchscreen and replacing it myself:
http://mobile.brando.com.hk/prod_detail.php?prod_id=03799
I've noticed this problem on quite a few of the original touch / elf / 6900 phones, including my old personal phone which I used in this condition for many many months without every having any actual issues. It is strange but like you said: pretty much not noticeable when on and probably just best left alone unless it really bothers you.
I have the same spot but it is not causing any problems that I noticed but there is many who have this spot in the diamond forum.
today i also noticed this on my touch pro..i sort of fell asleep on it and i think i might have messed it up
i can see that oil spot that you mention but only if i tilt the phone at a certain angle and only if the screen is off.When the display is on i can see everything properly
The problem:
Touch function is messed up badly..i tested in notes application and sometimes when i press at a point X the dot appears somewhere else on the screen...Internet browsing is a pain in the ass like this...
i also noticed one thing..i took the stylus out, put the phone next to my ear and i tapped at the area outside the oil mark. I get the normal soft sound and pressure feeling as it should be.. When i do the same at the oil spot its rather hard feeling and sound..
i will contact HTC on monday and see what they say about it..
otherwise i will get a replacement for 159euros (inc installation) from pdatech...
Happened to my Fuze...
Happened to me too 60 days into owning it. I carry all my phones in my pocket, but have never had this problem. I brought it into the at&t store that I got it at and they never saw it either (it is only a few months old for them and have not had any complanints yet). They were going to replace it for me but were sold out. They had me call the warranty department and they replaced it with a refurbished unit (although all of their refurbished units are brand new as of this point because the phone is so new for at&t).
If you got your phone through at&t call warranty support and they will swap it out if the unit is under warranty (which being 2 months old at this point it will be).
This happened to my Fuze as well. I tried to call AT&T support and visit a corp store but they ruled it as physical damage, thus voiding my warranty. Apparently the "crystals" under the display are cracked/damaged, causing the rectangle. Who knows.
has anyone successfully sent a touch pro raphael to HTC repair shop to be repaired under warranty with this issue?? its really bothering me that i can see it and i feel like it will affect my phone eventually...
Add me to the list too.. I am going to try to get mine replaced through Sprint if it gets bad. I hope they know this is an issue/defect and not something like water damage

I believe this is a design/quality issue. I posted about this same problem here some weeks back. HTC will not repair under warranty, paid in total 77 pounds to get this fix from them. I believe they are aware this is a problem because in the warranty book, screens are not covered even when its not your fault. They call it Newton ring .
Funny thing that a lot of people started noticing this issue very recently: as if a cheap component came to the end of its life cycle.. propably in my head only..
Anyway: I noticed this on my TP a few days ago and I'm going to drop my phone to the local service. It's the second time in just over 4 months.. crappy build quality really
also: Diamond users have had the same issue: http://forum.xda-developers.com/showthread.php?t=439410
Local HTC service got back to me: they're insisting that it's a 'mechanical fault, not covered by the manufacturers warranty'. Then it gets better: the estimated repair cost is 275 euros (that's roughly 355 USD) for the replacement of the display and front cover.
Naturally I'm going to challenge this as the oily patch appeared over night when the phone was sitting on a table.
not that im questioning what happened but personally i find it difficult to imagine how it can get the oil spot just by sitting on the table :S
normally you would expect this after exserting enough force on the screen. Personally that was my case. I sort of fell asleep on the phone and might have hit it on the metal edges of the bed..anyway i got mine replaced from pdatech.nl for ~170euros including installation costs..
Well if I had to venture a guess, I'd say that the 2h navigation on the night before took its toll on the display and during the night it just spread out and became visible..
how dodgy. I have been getting this problem, but funnily enough I thought it was due to air pressure, because it happened to mine when i was on the plane.
anyway i was just coming home from someplace real hot (40C), and it kept giving me the screen alignment problem for a few weeks, kept thinking i was pressing the top right corner of the screen regardless where I pressed. However, found that putting slight pressure on the screen for a few hours (i.e. a weight) fixed the screen alignment problem temporarily (for a few hours).
Anyway, just came back on the plane from someplace real cold (-10C), now the problem has ceased.
???? air pressure? or temperature variation?
I don't have the screen oil spot problem you guys have however.
Here's to it lasting a little while longer...
I asked for a more detailed report of the fault and the service just said that 'It's a fault defined as OOW (Out Of Warranty) by the manufacturer' and that there's nothing they can do but charge me for the repair. Note: they're not even putting the blame on me saying 'abuse/misuse'!
Now I'm going to go to the seller (expansys) and hope that they have some interest in keeping customers happy (and maybe have more business with them in the future!) and make things right (=fix my phone or replace it).
Wow, and I thought I was the only one. I've noticed the same oily stain after falling asleep on the phone. I've had it for a month now, and I've gotten used to it. It does not seem to affect the sensitivity or the accuracy on the touch screen. At least not in my case.
Does anyone have any experience replacing the touch screen by themselves? Is it a complicated operation? I would greatly appreciate a 10-step-guide on how to replace the screen, if it's going to be an issue over time.
disassembly guide
check out the wiki of xda click on service manuals and look for raphael. its on page 19 of the PDF
I noticed this issue on my Touch Pro today morning! I used my phone last evening and everything was fine. Now the touch screen doesn`t work at all. Great.
Same issue
I have also been victim of the oily patch.
I have had the Sprint Touch Pro since November and it just happened within the past 2 weeks.
Maybe this is due to not putting the screen protector on the phone.
I'm going to try visiting the Sprint Repair Center to replace it and then put the InvisibleShield Screen Protector on it.

HTC Fuze (Raphael)(P4600) TouchFlo 3D Not working

hi!
This is my first post here. I have the following problem: yesterday my phone was fine...today not. Yesterday I was using the touch screen as usual with no problem, today the battery was to low and I turned off the phone. When I get back home, I connected the phone to charge it, and PUF!! the touch screen was not working at all...sometimes I can tap some menu, sometimes not, but in general terms, I can only use my phone with the keyboard. I did a soft and hard reset and nothing happened, I don´t know what else to do. I see this is kind of common problem, but no one has a common solution. Any suggestions?
Thanks!
My phone has windows mobile 6.1 Professional. CE OS 5.2.19971 (Build 19971.1.2.6)
ROM version 1.95.502.5 WWE
Radio version 1.02.25.32
Protocol version 52.39c.25.22H
u were able to use the windows 6.1 explorer? like looking for files under files explorer with no problem?
my phone is just as new as yours, i feel so frustrated! I was able just to use the keyboard, no touch screen commands were functioning. As i said, I have seen too many people complaining about this (if I would have known that, I would´nt buy this piece of crap)

At any time did you apply too much pressure on the screen?
Is your d-pad still working?
What about other hardware buttons besides the keyboard?
As I said, one day was working perfectly, and next day a kept it turned off since the battery was gone, and I was not at home to recharge it. So basically one day was fine and 12 hours later was not. The rest of the buttons are fine.
I did a hard reset, and at some point of the process the device indicates that I need to align screen, so a small cross show up in the middle of the screen (yo oughta know how is this...) well: I tap the cross and nothing happens....I tapped again...and nothing happens...3 tries later, finally the cross moves and the process goes on, To complete the process it takes me about 15 minutes!!!!!! but still nothing works out, the align screen process starts over again, and thats it!
At least, before the hard reset I was able to start my phone....now is impossible
Dont know what to do...

well then you have several options:
1) bring phone back to the entity you purchased it from considering you stated it was new it should be covered under warranty unless you purchased it from eBay w/o warranty
2) If you know it is the Touch Screen then I suggest using xda search function and searching "Think your digitizer is broken" and apply it the Fuze rather than the Tilt
3) attempt to replace the screen
4) sell it "as-is" for a loss
Problem solved!!!
Thanks guys for the suggestions. This seems to be a very common problem. But in my case the solution was simpler than I would ever though!! I read in other posts that this unresponsive touch screen problem is usually created by particles of dust, (sand! in my case), stuck in that tiny gap between the screen cover and the phone body, and the solution was to gently pass a piece of paper thin enough, (flexible plastic CD cover, in my case) well....Having tested all kinds of software """solutions""", and been prepared to pay for an expensive fix (I live in Costa Rica, this kind of phones are not common use, so fixes are expensive)...so I gave I try to this solution...and surprisingly IT WORKED...there were lots of dust, and even sand grains stuck in that gap, and like the phoenix...my phone got back to life!
Its amazing how delicate are these devices!! I think they are intended for enclosed-temp-controlled-ultraclean places only.
I hope this helps a lot of people having the same problem.
Thanks!

More info needed on "HTC fuze touch screen not working"
Hey, Ive tried following the thread about the htc fuze touch screen not working... up until the part about sand in 'some space between something...'
can someone provde more context/ pics? of where the sand might be.. because it sucks trying to use the fuze without a touch screen.
thanks for the help.
and the HTC customer support immediate went to the "well just hard reset the phone"... how quickly they are willing to erase all that data and hours of work to reconfig the phone..
any help is appreciated...
They were talking about the tiny gap between there the top layer of the screen (the material you touch) comes into contact with the body I believe. What you can try doing is running a piece of paper or something thing enough to wedge out the dirt in that area.
another somewhat common problem is the newton ring. You'll see an oily residue in the center area of your screen (it looks like rainbows). What I believe happens with this is your screen gets stuck to the actually LCD display underneath and doesn't bounce back to go back to it's resting state. What some people have said is to get some sort of adhesive material and use that to pull the screen up gently, so it goes back to resting. People have used tape and the such. Just be careful you don't pull the screen off your device.

[Q] New joinee-About HTC one X issues

Dear members,
I would like to know the truth behind the issues faced by the HTC one X, which I read in many websites across the internet(and few here)
I was decided to get one for me untill last week, but the issues what I read for one X confused me.The issues that I came across was;
over heating(guess its obvious for smart phones)
Wi-fi issues(death grip issue)
screen/display flickering,
yellow spots on display,
Frequent black screens,
Restart troubles,
Music player issues(when music player stops when gallery is used)
Taiwan made phone's facing issues over Chineese made ones.
Kindly address these issues ASAP, as I had already made up my mind to go for HOX, so that I can buy one with relaxed mind...
I cant think of any other smartphones as of now.
Thanks in advance

I second this post and would really like to know how current owners are experiencing these issues.
Mine is a Rogers HTC One X.
Got it about 3 weeks ago. Just sent it in for repair, just outside the 14 day exchange range
overheating wise, yes, it can get a bit warm at use but same for any small tightly packed smartphone. I didn't have any wifi issues or any issues you had stated.
The problem with mine was holding the phone vertically. About half way down, there was a 1cm horizontal strip that did not react to touch. Just where the ok and cancel options pop up on some games/apps. You would need to rotate the screen so you could "tap" those buttons and get a reaction.
I turned on the developer mode and the mouse tracking/button press options and you can trace your finger down the screen and you can see where it stops then continues with a 1cm or so gap between where it wasn't responsive. This gap was the entire width of the screen not just a spot or two in that 1cm zone.
The phone was never dropped, bent, sat on etc. Mint screen and case, no case or touchscreen protection. This issue occurred quite suddenly about 16 days in, only noticed it when some games didn't let me exit when hitting the cancel options. Originally thought the game or the app was at issue. Then realized it was the touch screen. Did a full reset a few times, same problems. Now patiently awaiting for my phone back. Rogers phone/loaner suck as well, gave me a Nokia C3 POS as a loaner. Using my old motorola milestone instead.

[Q] Ghost Touch issues fix?

I bought this tablet off Amazon's Warehouse Deals. It came to me dinged and scratched up, but operable. I noticed the touch screen was a little off and would report false touches occasionally, but I didn't think it was anything to worry about. Like a kid in a candy store, I raced to get a new ROM so I could optimize this thing. In the process I unlocked the bootloader, rooted and installed PACman ROM. Ghost touches disappeared--gone for like 3 whole days. I'm ecstatic, and falling madly in love with this tablet. Then I notice the ghost touches coming back after the 5th day I have had it. Now its showing about 3 ghost touches almost constantly in one vertical line (in landscape) on the right side of the screen. Pretty much totally inoperable. I have scoured all ends of google, and most of the time it spits me out here, searching thread after thread of nothing but "RMA it". My questions are:
Is there any fix to this besides shelling out money for a new digitizer? Is that the general consensus that the digitizer is the root of the problem? I know I'm able to return the product, but does anyone know if Amazon is going to give me grief over an unlocked product that was a scratch-and-dent deal anyway? Any way I can re-lock the device? I've seen multiple threads with replies saying "lol didn't you read the blah blah? no way bro", but these were posted a couple months ago. Maybe something new has come up. I guess I just feel sorta rooked because I bought a defective piece of hardware, and now I can't get a refund just because I modified the software.

Same thing happened to my brother's tf300t. He returned it as defective, but I guess you could replace the digitizer. As far as I saw, it was a hardware problem, so it requires a hardware fix. Sorry

I got a similar situation in the last two weeks. The problem I have is that my TF300T is keeping rebooting by itself. I've googled it and people say most likely it's a hardware issue. I am trying to find a way to see if the device can be reset to factory condition so that I can return it for repair. Looks like we are on a same boat. Hopefully I can find a way to do so.
Just an update on my issue, in case anyone else stumbles across this particular problem. So far I have gone almost a week with no ghost touches. I popped off the back of the device (three guitar picks did the trick), and disconnected the digitizer ribbon cables and reseated them. Problem vanished. My best guess is that the keyboard dock puts odd pressure on the device. That mixed with rough handling is bound to cause some problems.

It could be the power button is jammed? I know mine is really touchy (all I do is tap it with my stylus and screen turns on/off. Good luck!

Thank you. I just got mine from Groupon as refurbed.. (they did a ****ty job, apparently) Ghost issue about 2 days after getting it out of the box. By then already unlocked and flashed CWM.. sigh.
I'll try your fix tonight. Any chance there is an image of the right connector/ribbon?
Hopefully the image quality isnt too bad. I took an exacto knife and gently pried up the black foam squares, set them aside and worked my magic. Hope this helps. Just be careful with the ribbon cable (duh). Hope this helps!

Thank you! I'll try this adventure later this week.
Did this today.. So far, 20 mins on it, and no issues. Typically took about 5-7 mins before. So, crossing my fingers this is gone.
THANK YOU! I can go back to enjoying my tablet
Im in the same boat with this Ghost Touches Issues, and its getting worse, sometimes im working at college and this Ghost appears and the tablet gets almost unusable, Only the Keyboard Dock saves me.
Please if you can give me more detailed instructions i think i would be brave enought to do this surgery to my tf300t, merry christmas!

i just noticed that when having a ghost touches attack, if i put pressure con the tablet, lime trying to bend it, the touches vanish.
I also have the ghost touches but it seems to only happen when the screen is dirty. As soon as I clean it off, they go away. Would a good screen protector help with that? I may go ahead and try taking off the back and messing with it.

I thought mine was fixed, but doesnt seem to be. I technically didnt remove the connectors.. I was nervous, they are WAY fragile. I simply unlocked and pressed firmly on them to attempt to reseat them..
Problem seemed to go away until I used Chrome. Chrome is what seems to trigger odd behaviors for me. I may try another browser and see if it still happens.
I've been dealing with this off and on for about 8 months; asus HAS to be aware of it as my tab has been back twice for this issue (out of warranty now) and I take advantage of their complaint form every month or so.
Here's what I've been working off of (based on personal experience/experimentation):
Re-seating the cables might help for a day or less, but isn't a permanent fix. I even went as far as strategic pieces of tape to hold the flex cables in place and tape across the connectors to encourage them to stay closed.
The first time I popped the back off the larger of the three flexes (with the silver wrap) had partially worked out of the connector on the driver board. Re-seated it and problem disappeared for about a day.
The large copper heat spreader was basically spot contacting the CPU and really wasn't touching the smaller ancillary chips (unit had been running warm for a few months, thought that might make things wonky). I pressed heat shield back down to ensure adhesion, and slightly molded the copper around each chip. Ghost touch gone for two days, unit way cooler running than before.
Here's the interesting one to me. Tonight I noticed that even just hovering my finger close to the screen I can get the 'touch dot' to show; this got me thinking about static. I held the tab in a way that at least one finger of one hand was touching the screen, like towards an edge (out of the active area) while using the other hand to touch the screen. Seemed like one hand was grounding the screen, like a charge couldn't dissipate from the surface.
Isn't this a "capacitive touch' screen? Could it be a matter of grounding?
I too purchased this tablet and dock from Groupon about 4 weeks ago or so as a manufacture refurb. My tablet does the same thing. After about an hour or so use most of the time it starts randomly acting like the screen is being touched. And it appears to only be in the upper right corner area (kinda where the lock screen pattern show up when you unlock it) in landscape mode. Sometimes it may take a little longer of use before it happens. It happens regardless if the dock is plugged in or not. I have figured that if I lock the screen and wait a few seconds and then unlock it. The ghost touches are gone for a while. I first began thinking it may have been a OS issue and hough about rooting and putting a custom rom on it. But from what I have seen on the web it doesnt seem to matter whether its rooted or not. So should I RMA it back or has any one had permenant luck with reseating the cable?
Thanks

I'd try reseating the ribbons. I kind of doubt it would solve the problem since it's a refurbished with a latent defect. Bad ribbons would strike at random but do not wait for a while before acting up. Look at the glass surface under a magnifying glass and bright light. Hairline cracks cause this after the tab heats up, but you can't always detect them. RMA would be the safe option unless you're really pressed for time.
Ghost touches are back. Noticed I had alot of them when my storage was full. Used a previous recovery (same ROM, just earlier date with less junk installed) and it cut down the frequency of them happening. This is so weird.
I had those ghost touches when 4.2 roms started (CM and AOKP and all of the rest of them. Then someone, I don't remember who had compiled rom with decreased touchscreen sensitivity and ghosting was gone. I think they started with PAC or AOKP, I really don't remember.
Then I went to 4.3 and 4.4 roms and I didn't have one single ghost touch since then. I do noticed sometimes when I hover finger over screen it is registered as touch, but ghosting by itself didn't occur on those roms.
one cent fix
I have an ugly, but effective solution working on my pad right now. It has been in place for about three or four months.
Holding in landscape mode, pulled the bottom left corner back slightly and inserted a penny between the back and the lcd. This put enough torque on the screen to kill all of the ghost touches and it still fits into the keyboard dock. There is an ugly gap where the penny is, but it is now fully functional.
Hope this helps some of you

Strange problem with touchscreen

Hello, guys.
Recently, I dropped my M2 on the street, resulting in cracked touchscreen and lcd. Replaced both the touch and the lcd, everything seemed normal until I noticed that the middle part of the touch (a line going from the left to the right, around 1cm height) doesn't work, it just doesn't respond. Later, I got another new touchscreen and same story - same part of the screen doesn't work.
Maybe we have some kind of defect touch screens here in Bulgarian stores? Though I bought the two touches from two seperate stores. Or it's possible that it's something with the lcd? Even though it works normally, no strange behavior, no black spots, scratches or anything. Or could it be a software problem? Using Android 5.0.
Thanks in advance.
More likely to be motherboard problem if it's the same with 2 different screens being installed
Thanks for your answer.
One thing I forgot to mention - when testing the screen in Sony's Sketch app or in the service menu, if I run my finger from the top to the bottom, or the opposite way quickly, sometimes, the lines my finger makes don't get cut, i.e. it's like the screen is functioning properly, with no dead spots. What does this mean?
According to Sony support, it could be a compatibility issue between the phone/touchscreen/LCD, what do you think?
