Permanent fix for unresponsevie and haotic touch screen

I had Issues with the the touch screen. My touch sensitive keys need 3 or more touches to work, sometimes were not working at all, touch screen was choppy and low responsive when touching even after I installed firmware 3.33 and the diag tool and tried every method.

I`ve got very nervous and decided to take the phone apart.

1.After taking it apart i started cleaning the touch screen. I took out the abrasive bands that hold the touch screen (when you take it out don`t peel it, roll it to the margins till is out) then with medicinal alcohol i cleaned avery glue remain from them, cleaned with a piece of material and dried for 3-4 sec with a hair drier (If you do this you must be very carreful on the top part of your digitizer) then put the digitizer on a flat surface, face doun and started pressing with a soft material on it like I was cleaning it, with circular moves (I did this because the digitizer is made from two parts, the plastic part with the circuits and glass part, I did this because I tought it is possibile the parts to get unsticked). After i finished doing this I took an isolating band and sticked exactly on the margins of it covering the white circuits. At the bottom do not put band on soft keys just on the glass part, after finishing thist i cut the margins with a cutter blade. After finishing isolating the digitizer I putted over the isolating band a double abrasive band in the place of the old one that ii took out so it will stick back to the display part.

I think this is the most important part because isolating band stops digitizer to make mass with the lcd

2. On the bottom of the screen part you will find the buttons led circuit band. On the sides of this band you will see that is sticked a little and thin piece of isolating band, over that i sticked a little piece of isolating band of mine (carrreful not to put it over the led circuit band, only on the sides) then cleaned the lcd too.

3 After getting everything ready start reassembling the device, and be sure that the digitizer connector is well inserted in the slot (with caution not to brake it). After placing the circuits board and connectors, take the plastic part where the battery sits, on the back you will find an aluminium part with four pins, bend them out at, lets say 45-50 degrees then bend out the grounding pin presented in the first page method too.

Now assemble the rest of the phone and test it.

If something is not working then verify if you didn`t put abrasaive abnd on the transparent part of the digitizer. I say it again you must put onli ond the circuits on the margins of the digitizer except the bottom part where you must put the band only on the glass part under the sensitive keys.

Hope I helped you too.

My touch screen is now working very good and the capacitive buttons too.

Do it carrefully and at your own risk!

Tips for future reference, my help is at your risk. Some of the digitizers is responsive of what I'm describing and other's haven't

How to tell if your digitizer is not responsive/ not genuine​

Tip 1: Only 2 fingers work on the screen (some imitation digitizer's do work with more than 2 fingers so be alerted by this tip)

Tip 2: Some who have had it not responsive have reported the digitizer to have an blue "EL" sticker

Tip 3: Those who had the blue "EL" sticker digitizer have reported to show APT_Keep_in_high or APT_Too_High in the .nbh calibration tool

Tip 4: If it's cheap; it's probably a fake.

Tip 5: Turn on show touches or use a multi-touch tester and see if they follow your finger

Tip 6: If your buying a HTC Sensation from gumtree check that the phone has enough charge; since people tend to sell these broken digitizer phones on there with 1-2% of battery to mislead them.

Just replaced my lcd and digitizer. The new screen is a fuzzy AUO. Trying to exchange it for a new screen. Is there another way to fix this with drivers or do I need a new screen altogether?

Solution

I’m having this problem since purchase, and found it the most convenient workaround to view the screen touch input, via developer settings. Turning the display off and on would reset the digitizer, but it also ended a potential incoming phone call or YouTube video. Then I disabled the lock screen with the ‘no lock‘ app, to skip the login routine to get at least rid of the slow login delay. This problem also appeared more than usual when in docking station (charger) and when receiving calls (since I was unable to pickup the phone).

Recently I found this tread, and decided to signup and try out all the solutions. I tried the aluminium trick, and I even experimented with all other contacts including the SD-card reader contacts.

Especially the hint to leave the case open inspired me to isolate the contacts with some ordinary transparent tape (opposite of the aluminium trick). And after 2 months of heavily using my phone, I can hardly remember when the last time was that I had to do deal with the first workaround. But in the end I was able to receive calls again, use on-display keyboard and use the phone when charging too. My phone don’t show any significant degrease in network, Wi-Fi, Bluetooth signal or FM-radio, and even the MHL to HDMI video adapter won’t show the usual lags anymore.

So I hope this post can help for others too! :laugh:
[HTC Sensation] harsh.deep:
Ok so the problem i have is pretty anoying. My screen has random touches everywhere on the lower part of the screen. Hence making it up operateable..Just random 3-4 multi-touch points on the phone ( i saw this when i enabled the pointer) . This happens on low battrey levels or when fully charged..On medium levels i have minimum touch points (only if touch the bottom part too much). I bought a new battrey as well. I dont know what seems to be the issue here..Any help guys?
[HTC Sensation] -Jonny-:
Why post twice?
[HTC Sensation] eyeman_aimo:
sounds odd but it is trueee..

hi guys, regarding the unresponsive screen.. i have experienced countless times of unresponsive screen whether during receiving calls, recording videos, playing games and even leisurely scroll around the drawers..well, that's this thread is all about.

so, the thing is, when i read the thread starter post mentioning about "silver square" and i started wondering by myself "where is the square?" and i discovered it is on the phone body..but i suddenly noticed that i don't have the silver squares on the inside of the phone back cover..so, i'm thinking again is this the problem that cause the unresponsive matter?

however, when i tried the slightly pulling out the pin. it works for a day and i have to keep doing the trick to make the screen free from the problem..it's getting sick..it's like have a hope but fading out each time.

SUGGESTION FOR SOLUTION:

1.Do I have to paint by myself the "silver square" using electrically conductive paint?

2.Can i just make the square using the recycle thing like aluminium drink can or maybe aluminium foils instead of the conductive paint?

That's all..thank u..hope somebody could help me on this.

Worked well after changing my Touch Screen, thnx.

very nice
[HTC Sensation] invisible132:
Hi. When i swipe my finger vertically across the screen, it acts like i release my finger from the screen somewhere in the middle. Looks like there is a small gap which is unresponsive. Is it digitizer problem? Could it be because i've changed digitizer few months ago and digitizer cable beame loose?

water damage !!

hi guys ,

my sunny is 3 years old ,unlocked ,supercid,fw 3.33,running viperone sense 5 rom,very good condition till yesterday,it was kept in bag along with chilled waterbottle for more than a hour !!.after that the screen in not responding!! removed the cover ,i could see water droplets present over battery & its compartment,i cleaned it & dried .the screen touch is not responding!! tried few methods like draining the battery ,keeping device under sunlight for few hours ,no result!! but the screen got dead pixals at bootom of screen after keeping under sunlight !!,

the capitative buttons also not working!

flashed another rom,no use.using non touch cwm recovery to flash roms.!!! tried to flash stock ruu butit failed with usb errors!!

any suggestions?? should i change digitizer?

thanks

Edit: after keeping it under Sun for half a day ,it remained same,but for dead pixels, to remove them I kept the device in deep freeze for the night !! Viola !! The screentouch came back alive !!! Phone nowrunning perfectly .
[HTC Sensation] abachhd:
Found a new fix!!!!

Well, after trying all the solutions above, I always managed to keep the phone working only for a couple of days. The problems always used to come back. The screen would operate on its own, calling random persons and clicking pictures of its own. I replaced 4 different batteries, did soldering, pin adjusting, discharge cycles etc. But the problem always came back.

I didn't replace the digitizer because I was sure it's fine, otherwise the screen would have stopped working permanently. After months of testing and experimentation, I discovered that my problem was caused due to static current surrounding the touchscreen digitizer. It didn't have a screengaurd on it. So I went out and put a new screenguard, so as to prevent the static current from spreading around in the screen. The phone has been working like new ever since :)

Please note that this may or may not fix the problem. It fixed mine, so I thought I'd share it with you guys. Good Luck
[HTC Sensation] pollonamid:
This fixed my issues. Thanks
[HTC Sensation] zyetonysmith:
I may need this nice fix soon

sometimes i cant unlock the screen..
[HTC Sensation] palm_pilot:
Wow! Its like I have got my old phone back! Thanks :)
[HTC Sensation] john_1988:
I can confirm that the tape solution still works

After a decent test period of several months, I can confirm that the solution that I have provided the 31th of January 2014 still works. Just ordinary transparent tape at the contact. This is still THE (best and cheapest) solution in my opinion... Can anyone confirm this?

Sensation touchscreen.

Newbi here folks, and English too, so please play nice.

Reading through this thread today because my own Sensation has been showing these symptoms and one of the solutions you guys came up with has worked for me so far, so, many thanks. But, reading on through the thread some things came to mind. I used to be an agricultural engineer so I work at a very basic level as far as electronics are concerned and the first thing that ALWAYS goes wrong with microelectronics in agriculture is water/dirt ingress and the resulting corrosion. My screen nowadays has a nice fan of dirt particles in both top corners of the screen where the double sided 'sticky' tape has given up and, looking at the contacts between the phone back and main chassis they are plainly filthy. Where dirt gets in so does damp so it's safe to assume that some corrosion has started. This can all be got rid of with contact (electric not eyes! :) cleaner on a brand new small size woman's eye makeup pad from the chemist. Remove the battery first! Also, living as we tend to now on manmade carpets wearing manmade clothes we all have substantial buildups of static electricity on our bodies which microelectrics hate. Before you go delving into any parts of your exposed phone interior it's good practise to earth yourself properly. The folk who do this stuff professionaly each day all wear an earth bracelet while they work to prevent the buildup.

Good luck and keep up the community. Many thanks.

My touch screen is acting weird.. Its like some alien is touching my screen :'( its happening on one part of the screen tho...I always used it while charging I always used to drop it :'( what to do with it now?
[HTC Sensation] reynard80:
I'm having touchscreen problems after I dropped the phone.

The bottom third of the screen does not react well, as well as the 'hardware' buttons. Symptoms are like the symptoms mentioned in this thread. However, the solutions with the pin, and leaving the battery out overnight didn't help. When I use a Multitouch tester, it show that I'm touching with two fingers alternating on certain horizontal lines on the bottom third of the screen.

Might a faulty digitizer be the problem in this case?
[HTC Sensation] j_r0dd:
I wish this would fix me issue because I am tired of sending it back to htc for an issue they are not fixing. My screen responsiveness was fine until I sent it in to HTC because I had dust under the screen. Mine came back from them with this unresponsive issue. I sent it back to them to fix this after I tried the foil method. I just didn't want to risk doing any hardware damage. I received it yesterday and the issue is exactly the same. My touches intermittently don't get registered on the screen and the menu & search capacative buttons hardly ever respond. Really I don't even want to send to HTC to repair. I want a completely different phone. HTC's quality control is absolute ****. It's too bad because this is supposed to be one of their flagship models. I am at a complete loss here. HTC can't even fix their own devices.
[HTC Sensation] zmfl:
You didn't really have this issue than. Lucky :)

You are right about the quality control. Or quality in general...

So the fix didn't work for you? Maybe try again and be more patient... Or get A SGS2, that seems to be a popular solution :)
[HTC Sensation] thasp:
I never had this issue.

I cracked my digitzer, and didn't have the issue.

I changed my digitizer with one that says HTC in the center. It doesn't say T-Mobile.

This problem rears its head no matter what solutions I try.

I am getting a few more digitizers tomorrow. Putting the cracked one in(dug through nasty trash to do this) results in a perfectly working phone.

What sucks is having a $500 doormat in the case that there are no aftermarket or original digitizers available that allow the phone to be usable.
[HTC Sensation] mariohu:
Excelent post about touchscreen issue (found through gugl).

My phone is HTC Desire and I have the exactly same problem.

My questions are:

1- Do you have any idea where the "Silver pin" is located in HTC Desire?

2- Is it possible that that the location of this "silver pin" could be de same as in HTC Sensation?

3- Would I damage my phone if I put a "small piece of aluminium foil" in a "wrong silver pin"? For example, the HTC Desire actually has a screw or bolt in the place where the HTC Sensation has the "silver pin", and I guess that is a candidate place to put the foil.

Any help is welcome. Thanks in advance.
[HTC Sensation] zmfl:
I'm guessing you have something like this? I don't know what app the guy in the vid is using. If you want, perhaps you could try this one, or something similar.

Anyway, since I don't have a Desire I can't be sure, but from this pic it would seem there is no grounding pin. Also, there is no "square" on the back cover which would indicate a grounding point.

So... It could be grounded trough the sim/memory card slot? I don't see any other metal bit that could do it... See if you have problems when you touch just those points. Or any other point that you think would work.

It could be that it's not grounded through the back cover at all :\

So, to answer your third question, I doubt you will damage anything, but that doesn't mean you should cover your whole phone in foil :)
[HTC Sensation] undercover:
I have a Desire, and never had or heard of touchscreen problem.... Something else is wrong in your case,I'm quite sure.
[HTC Sensation] jjdoctor:
Nice thread... Luckily my sensation doesn't suffer this issue
[HTC Sensation] zmfl:
The link I posted suggests otherwise... Maybe you missed it from the xda app - http://www.youtube.com/watch?v=s30h7Uh6-CI

It might not be exactly the same like ours, but it does look like a grounding issue.
[HTC Sensation] claud_face:
idk if this is related but my phone never had this issue until today.

Thing is yesterday I was working and left it in sun streaming music for couple hours.

My fault and I deserve it but now I have lock screen and touch screen issues.

At first I thought was the rom but switched couple and same thing.

I guess maybe it heated up so much that it messed something inside.

Im so mad that i left it outside wtf was i thinking, I tried these solutions but its obviously gotta do something with over heating or something.

Anyone have ne ideas?
[HTC Sensation] mariohu:
Thank you guys for your responses, all of them were helpful.

I do not want to bother you nor the forum because this thread belongs to Sensation not to Desire,

but given that the synthoms are similar to both models, and acknowledging your patience, I will clarify some facts only "for the record" for all of those who are having/will have similar trouble (hope not).

at zmfl:

The problem is more like this http://www.youtube.com/watch?v=xlNArVn7otA , except that I can not unlock the phone because the phone does not even recognize any touch.

The phone is not rooted, uses original parts (battery, memory, etc), not dropped, never get wet, bought in december last year.

After a randomly period of time, the touch screen starts working normally, responding fast to all touches -even multi-touch- in all the screen surface as if nothing had happened, and suddenly the screen back againg does not response to any touch.

I have tried what you suggest, touching sim/memory card slot area, and the screen starts recognizing touches... for a while and then back again. Also the problem usually disappear when I remove the battery for a night or more.

I guess it is the same problem that Sensation's: "some extra charge is not getting the ground", but I am not sure.

at tinky1:

The htc desire forum in http://xdaforums.com has various post like this one http://xdaforums.com/showthread.php?t=895625&highlight=touch+screen.

I have already done factory reset and sometimes the problem disappear... and then backup again.

I have read that the htc support people is aware of this as "the screen issue" and offer you a replacement for another phone.

The problem is that these days I am working far away from an authorized support center to get a replacement.

I agree with you that something is wrong, buy it is so wierd and random that it is hard for me to find a pattern of behaviour about the problem.

at claud_face:

I have not run through your situation. I would recommend you to go to authorized service.

I will keep searching. Whatever I find, I would post it.

Thank you very much for your time. The community spirit is powerful.

^^^^^^Looks like its related to infamous motherboard issue. Do you get random reboots under stress by the chance? I had my mobo changed.
[HTC Sensation] akusuma:
Opposite grounding problem ?

I am having the same symptoms, I am unable to use 4 main button below the touch screen, but i am able to use the touchscreen fine. This happen 1-2 weeks ago, since I purchased it last June.

I tried one of the solution by lifting the silver pin and additional aluminium foil but it still did not worked, until I realized it was the opposite!!

Testing the same test as the youtube video.

If I put the HTC Sensation on the table, and touch the 4 button, it works.

But as soon as I touch the body and touch the 4 button, it did not worked!

I tried to isolate the grounding (literally with a cellotape), it still the same!

I think it is because there are still other golden pin that connects the body

I've factory reset, and tried different ROM. And even do a key test on the recovery mode. I conclude this is a hardware issue, and this grounding might be the issue.

For now, what i see as a workaround is to make sure that I did not touch the body when I use the button, by using a case (which I dont have yet)

I might add pics and vids later
[HTC Sensation] claud_face:
Ok I definetly have problem with the unlocking. Besides that thoug once it unlocks its perfect . Zero problems.

Sometimes it unlocks just fine and as if there were zero issues.

Such an annoying little problem.
[HTC Sensation] zmfl:
@claud_face:

That's how the issues start usualy - with the lock screen. You could try what I wrote in the first post:

Then do not touch the screen while charging for the next couple of days. And also, pull the pin out a bit more before doing any of this :)

If it goes away, there you go. If not, you messed up something else...

@akusuma:

The only thing I can suggest is the same thing I just suggested to claud_face. Doing that discharges the static and might help :)
[HTC Sensation] claud_face:
Ok so if my problem is the static thing are you saying this is a hundred percent garanteed method???

Why would some people have this and others wouldn't?

Besides the grounding pin which makes sense but did.t help in my case.

Thanks.
[HTC Sensation] zmfl:
That's usualy how it goes :rolleyes:

I know I'm repeating myself, but to know for sure if you have static electricity (grounding) issues you should do the same thing I suggested above. If the problem goes away you can start looking for a way to ground your phone.

If not, you might have a faulty motherboard, like tinky1 suggested. It does seem Desires in general (including Desires S and Z) have a really touchy motherboard :|

I'd say 99% :)

The method I posted is a modified version of what we what we came up with in tinky1's thread quite a while ago. That's the method most of us used before we found the silver pin.

So, if you do it properly (repeated charging with NO TOUCHING :)), the issue will go away. If it doesn't, the sun fried something...
[HTC Sensation] undercover:
Yup, using it myself and other users reported success. The process discharges static but DOESN'T fix the cause.

Read op and last 5ish pages of my thread.
[HTC Sensation] claud_face:
thanks guys,

I will do the steps and let you guys know if problem went away.

When Im recharging does it matter if phone is on?

And when u say not to touch screen could I touch the case?

Like I should unplug from charger adn then I could touch as much as I want right?

Thanks alot guys.
[HTC Sensation] undercover:
Doesn't matter if it's on or off, try not to touch it while on charge unless you have to. Then touch as much as you want. Problem might not disappear right away, 2 or 3 cycles might be needed. Good luck.
[HTC Sensation] zmfl:
Yes, it can be on, and yes, you can touch the case. Once unplugged you can use it normally :)

edit:

tinky was a minute faster :P
