[Q] touch screen not working - Click General

Guys,
today I was about to make a phone call but couldnt unlock the screen. It didnt work at all so I rebooted and now cant enter the SIM lock. It has happened to me before but reflasnihg a different ROM helped. However i now press the screen it doesnt react. Ive tried to reflsh sveral ROMs but no change.
I never dropped the phone or anything like that...
can anyone help please?

I have another kind of problem with the screen. When I tried to replace the screen protector upper layer of the screen comes off (not completely) and then the touch becomes badly misaligned. I tried calibration but never success with error saying invalid calibration point, like that.
so, I think tattoo screen is not robust and prone to problems.

I managed to soleve my problem. I took the phone appart and pushed the digityzer connector (ive replaced digityzer some time ago due to scratches) more into the motherboard and now it works all fine...

White screen?

I have an unlocked Cingluar 8525 (TyTn) I have had it for like 5 months now. Upgraded to WM6 as soon as I got in in July. Recently it has started slowing down and lagging a lot. So last night I restarted it cause it froze. When I did that it would freeze on the WM startup screen. So I rebooted while holding the 2 soft keys and then clicked yes to restore. That worked. Then today the phone fell off the arm rest of my couch onto carpet and I went to go send a message and it was all white. So I restarted and now everything is just a blank white screen, no startup logo or nothing. Has anyone had this problem before? I tried resetting it again and it didnt work. I have tried turning on with no sim card and same problem. Anyone know how to fix this?
It is all too common,
I've been told it is due to a loose connection between the ribbon that attaches the screen to the mother board.
I think its a design fault - the ribbon is linked to the two parts of the Hermes (screen and keyboard) and surely all that opening and closing is essentially moving something that is designed to be a static item. This I think weakens the ribbon connection, causing the white screen of death as I've nick named it.
Here is a link to dismantling the hermes to reconnect the ribbon.

Though you should know I attempted this tonight with very little success.
I still have the white screen issue. Its very frustrating that the reason I bought this phone (the slick keyboard action) is the reason I cant use it anymore.
Hope you have more luck that I did, Let me know...
PS - If you have never taken it apart before (I did to replace the screen) It should still be under warranty - or if yours is second hand - you could send it to apex laptops for repair.

Major touch screen problem with touch hd!!

touchscreen was working today morning, took battery out for 2 hours, turned it back on and it was working abit weird, and now i cant press any touchscreen buttons atall!
So no softkeys (pick call, home etc.) and nothining on the big screen! I can turn on the phone, press the power button and volume buttons, see my home screen get calls etc.. hard reset twice, took battery out, nothing does it .. gonna try flash it but dont think itll do it ... and ideas?
Im in uk aswell if that makes a diff
Dear All,
I have similar problem. Usuallí I use on my HD NRG ROM. About 3 weeks ago I updated to the latest NRG WM 6.5 23xxx ROM with Sense 2.5 Maxmanila version, and since this upgrade the touch screen position moving randomized up or down from 2 mm to 30mm!!! After this ROM I tryed updating each newer version, but not changed nothing. I need realign the screen about 10 times / day!!! The phone I never dropped or cracked.
Can help me somebody what happened with my HD?
I had this happen to me yesterday. I was surfing on my phone as per the norm. Put my phone down. Got a txt, picked it up and it wouldnt allow me to access it. I thought it must be a freeze as it has happened occasionally.
So I restarted.............and nothing. No response AT ALL from the touch screen.
I have noticed the oily spot problem on the most part of my screen, and thescreen doesnt have that little give it used to when using it (paranoia possibly)
So I can only assume something has given within the screen. Ive been searching all day on the internet for causes and fixes but nothing has come up.
The volume and power buttons work but I cant do anything at all with the phone as its obviously all touch based.
Is this a screen replacement job then or is the whole phone goosed?
Roheelshah if you turn your phone off do you have the massive oily screen thing?
Any help is most appreciated....
I had the same thing, a oily spot, but it was there for months, then i noticed another new spot (looked like a tiny tiny burn) and thats when it stopped working completely... ive ordered a new screen which should be comming in a few days, im hoping thats the issue
will let you know if it works ....
keep me updated if you find anything
thanks!

whats it do? and where from??
I just posted something like this a few days ago, pulled my phone out and screen wouldnt respond, had these marks all over my screen, "swirly marks" as i describe it, very well could be the oily marks you are talking about. you can move them around with your finger right?
anyway, i took my sim out, tryna find a spare phone, couple hours later the marks were gone and screen started working again, touch wood its been fine since.
no idea what happened, but try letting it air out or something
ok basically i received a new digitizer today (the actual touchscreen) ...
i dismantled the whole phone using the service manual and some video some guy made (VERY HELPFUL, if anyone wants it for any reason i can post a link), ok so i got rid of all the top bits, the circuit boards (or watever theyre called)
I got down to just the bezel, lcd and digitizer (dont know what a bezel is, the lcd is where the display actually is and digitizer is directly stuck ontop of that)
Apparently when replacing the screen, htc have made it so that you have to replace all three of those parts instead of individual ones, but you can buy them seperately so i thought i'd hero it.
i poked out the screen from the frame (some chewingum like stuff holding it in) then i started peeling off the digitizer (if you get one and want to try it you'll know where to peel) ... this was a mistake tho cause the lcd is unbelievebly sensitive so while peeling off it left scratches on the lcd, and me not knowing the lcd is sticky tried to wipe them and use a dust free cloth, which left alot of crap on the actual lcd!
i managed to get the digitizer off and ripped the cable that goes from digitizer to whatever reads our fingers on the screen, took it all off, placed the new one directly ontop and fed the wire exactly how it was for the first screen.
Put it all together again
Now I did mess up my screen badly, but in a good way! .. i now have full touchscreen working (smoother than ever) but my LCD display is near enough gone, so it looks like the screens really really dark, and i have to tilt it at certain angles to see the screen..
After all of this i now have a touch hd i can controll from my pc (using mymobiler) so i can recieve calls, send texts all from my pc when connected thru active sync, can even play teeter ... but not really the same!
I wouldnt recomend anyone to try what i did, although i think its worth the risk as I would have to replace the lcd anyways if i wanted a new screen in the first place... and who knows you might be able to peel the digitizer off clean (NEVER EVER EVER TOUCH LCD WITH ANYTHING!!!).
It all cost me around 10-15£ for the digitizer and screwdrivers and alot of hours dismantling phone compared to 50-100£ for a new lcd.
I am either going to get a new lcd now so i can actually see the screen, or get a new phone.
Sorry for the essay but hopefully this helps someone in any similar situation
if i do get a new lcd will post how it goes and if it sorts out everything
if anyone knows of any other reasons why my lcd would be so dim (brightness is 100%) accept for me getting carried away with it ... help would be appreciated

Yeah swirly oil marks is how myne started ... i think i finished off the screen by trying to press hard on the mark to try and clear it .. . so be careful with it.. but think that overall the screen had seen better days (course only a few weeks after warrenty finishes) ... all conections inside were ok aswell

Same here. Touch screen not working. Phone never flashed, droped,...
Any solution?
unfortunately, a friend of mine changed the touchscreen without success. Phone was in perfect state, no drop, no flash. Just the touch not responding. I'm not sure that changing whole part lcd+digitizer solve the problem.
Hi all!
I've got similar problem with my touch HD. It's stock since I bought it. My touch sense was acting weird, like it wasn't properly calibrated. Like, when I press 7 on phone pad, the phone actually presses 1, and if I press 0, phone presses 5 and so on..
I've tried to align the screen, but it doesn't get aligned the first time. I have to repeat the process about 4 times before it gets aligned. That's good for about few minutes and the problem is back. Hard reset was also done, 2 times.
Could this be a fixed with a software update? Does this mean that digitizer will soon be dead?
Thank you for your help
Regards

Hi!
I've successfuly installed the cab file on my phone's sd card, but the problem is still there. I don't know where the installed files are, do I have to run this application?
Thank you for your help!

Just did the hard reset. When it asked me to align the screen, I just couldn't align the top left corner. I had to press it like 50 times before cross went to the lower corner. Otherwise, after the align it's good for about couple of seconds and then it's just pressing all over.
I thought I had just some software issues because the screen wasn't dead, it responded to my touch. So, I'll probably have to buy a new screen and digitizer, right? Or do you have any other ideas?
Thank you again for your help!

firstly screencal installs calibration settings not for blackstone so do not install it, no point. (btw it also increases device touch sensitivity)
secondly you guys should try and install the calibration settings for blackstone, basicly what the align screen does, not sure where to find them for download but i could post the registrys if someone wants to make a .cab from them. (atm i cba making the .cab but i am able to do it )
if the calibration settings do not work i think it is best to buy a new lcd package (or buy new device and give me old one for spares oj)
Rn
hi buddy ! What you mean GSensorCalibrator ??
i didnt mention anything about gsensor calibration dude.
tried and tested screencal the other week and it screwed my blackstone.
install these instead:
*screen calibration, sets the blackstone touch points: (aligning the screen)
if you install a cab with these registrys it should fix the alignment problem.
(if it doesnt then its hardware issue = lcd etc)
[HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\TOUCH]
"MaxCalError"=dword:8
"CalibrationData"="511,542 183,881 183,198 834,197 833,880"
*this one will maximise the touch sensitivity for those that want it:
[HKEY_LOCAL_MACHINE\Drivers\TouchPanel]
"PressureThreshold"=dword:0
Rn
Does anyone have a recommendation where you can buy a digitizer and lcd from?

[Q] black screen after screen replacement for samsung focus

i just replaced the screen on my focus n i used it all day n made some calls then all of a sudden the screen went black on a call n it hasnt come back on since. i have tried taking out the battery, plugging it into the computer, i even updated it. and still yet a have a black screen. the touch funtions still work i can use the phone unlock it select things i just have no display. please help
Screen issue? You might need to take it apart again and check the connectors...
i tried that today n still no luck
As I said, screen problem? Although new, it might be gone. Which might also indicate another issue related to the screen (some circuit overloading?)

[solved] Yotaphone 2 front screen touch input no more working

Hello,
Since a few days, the touch input of my front (LCD) screen stopped working. Nothing looks damaged, the screen still displays what it is supposed to, but there is no reaction to my inputs (actions on volume and power buttons do work, as well as on the e-ink screen). Did this happen to any of you? Any suggestion on possible ways to fix it?
I should also mention that it still works by moments, like half a day working, then 2 days not responding, etc. I tried shaking it in different ways should a connector be slightly displaced, with no success: the few times it started working again came like a (good) surprise. I also had the great idea to do a factory reset, so now the phone is stuck on the Android configuration wizard, which must be done on the front screen (no possibility to use YotaMirror, apparently).
Thanks!

i recommend reflash it. possibly and more strongly recommend to flash the same version and region which was installed for example HongKong 4.4.3 baseband number .HK1.0.36a

Actually, I forgot that the front screen was replaced several months ago (by a repairer that mistakenly changed the front screen instead of the e-ink one which was having an issue).
The factory reset didn't improve the situation, the front screen becoming "touch-insensitive" every few days. After checking how the screen connectors are supposed to be plugged (opposed to the screen), I noticed that gently tapping the phone front screen down helped to solve the issue each time it happened. A few days ago, I finally opened the phone (quite easy, there are two useful videos online) and unplugged/replugged the screen connector. It has been working fine since then.
If it happens to anybody (who would have its front screen replaced), I hope it can help!

Touch screen occasionally unresponsive

Hi,
I own an Oneplus 2 for over a year now, in which I had to replace it's display two times . The first time I ordered a new display+digitizer assembly and replaced it myself, went great and everything worked fine. The second time was a month ago, I ordered the exact same display from the exact same seller on Ebay and did the replacement. I tested the display before assembling the Phone and it worked as it should. But an hour later when the phone was already assembled I discovered that the touch screen was completely unresponsive
After some trial and error I came to this conclusion:
the problem seems to be caused by applying a mild pressure anywhere on the bottom right quarter of the screen
the display does always respond when I hold my finger on it (with or without applying pressure) for about 4 seconds, then it sees my finger and I can swipe around (while still holding it down)
if I try the method above a few times, or let the phone rest on a desk for some time, the problem disappears and the touch screen works fine again.
So far, it looks like a hardware-issue, maybe a faulty screen or I messed something up while replacing it. But it gets weirder:
My OP2 is rooted and at the moment of replacement, it was running Lineage OS 14.1 (nightly, 2017-03-30). And when I wanted to update that to it's newest build, I realized that this whole touch screen problem doesn't exist in the TWRP recovery interface. It worked perfectly fine even when I tried to recreate the problem by applying firm pressures on every spot on the screen. So this made it look more like a software-issue, however the update of Lineage didn't resolve it and even restoring my backup of OxygenOS 3.5.6 didn't help.
I found this XDA-post about having firmware issues for the touchscreen with Android 7, but running their fix did not resolve anything either.
Right now my phone is pretty unusable since having it in my pocket is creating the problem. :crying:
Does anyone have any ideas of what the exact problem could be? Or anyone having similar issues? Why is it that there is no problem at all when booting into recovery (TWRP)?
It looks like loose connections between the display and digitizer.
After all it was a hardware issue. I disambled the phone again and after a lot of trial and error I found that there was something that came in contact with the back of the lcd that must have created a short cicuit or something. I placed a thin sheet of paper on the back of the lcd to prevent this and it all worked again! Still weird though that it didn't happen in TWRP.
