It does come back from time to time :)

I don't like disagreeing with tinky, but you don't have to be careful with how you charge. It's not much of a fix then :)

Here's how I do it... Every few months I pull the pin out a bit, perhaps add a bit more foil, or swap out the old one. Then charge with no touching a few times, and it works like new again.

Basically, just do the fix when necessary, which is not often :)
[HTC Sensation] jabirrockzzz:
can any1 clear does it also effect sensation xe?
[HTC Sensation] undercover:
XE, original and 4G Sensations are identical phones. So yes I'd think potentially it can affect XE.
[HTC Sensation] hasan69:
Bottom of the screen

Certain areas of the screen become unresponsive with no apparent reason behind it.

I read post # 1

But did
[HTC Sensation] hasan69:
It is difficult to touch my phone

Is shown in the picture

Multi-touch works on automatic:(
[HTC Sensation] zmfl:
If you have automatic multi-touch, and it is always in the same place, that could be the digitizer...

You can't fix that yourself. You need to go to a service center.
[HTC Sensation] hasan69:
What digitizer؟

Not always

Whenever that is multi-touch

I should have a power button and re-open

Is it still digitizer?
[HTC Sensation] TONINO_CT:
happens to me when I'm loading the letters to write go wrong, I will download it completely thanks;)
[HTC Sensation] hasan69:

And then got out of the battery

And left for two days

Then put the battery and installation charge

Until the battery is full

I then switched

Healthy Touch worked

But after a day or two before I was like why?

plz help me

I'm about to buy a 2nd hand sensation which has a problem with the unlock screen. It takes about 10 times to unlock the phone. After unlocking the phone seems to work perfect. It's not incidental but every single time the phone is unlocked. Does this sound like the problem that is related to the pin?

Thanks in advance :D
[HTC Sensation] undercover:
Follow full charge and discharge instructions in the post no1

Depends. To know for sure you need to do full charge discharge thing few times. Pin doesn't FIX the problem, it prevents it from appearing, so pulling it will unlikely have an immediate effect unfortunately for you.
[HTC Sensation] zmfl:
That, but first pull the pin out a bit more. Like in the pictures :)
[HTC Sensation] subbase:
Off course but I'm trying to do a risk estimation. If I buy this phone with 10 times unlock problem, what is the change that I can solve the 10 times unlock problem with this trick? How likely is it ;)
[HTC Sensation] zmfl:
Quite likely.

Try spinning the carousel a few times.

If you have this issue, you won't be able to do it 90% of the time.
[HTC Sensation] subbase:
Ok, so if the carousel works flawless then it is not (likely) this issue and I should not buy the phone as I would not know how to "solve" the login issue. How strange by the way if only unlock fails ten times and after that no issues are there any more? Does not sound logic to me ;-)
[HTC Sensation] zmfl:
Most likely there's a few more issues, you just didn't notice them :)

For example, if you tried typing a couple SMSs you'd get lags and missed letters.
[HTC Sensation] subbase:
Ok, so I have the phone.

Software nr = Android revolution HD 6.6.7 4G-XE by mike 1986

Android = 4.0.3

HTC sense = 3.6

Every time the phone is locked it takes serveral (4-8) trials to unlock. When it unlocks, it takes some time before the screen fully functions. The buttons in the black underscreen for example start responding some times 10 seconds after unlock.

After that the screen function properly for the short time I have used it. Only after a call the home butten and such did not function again for some time so I guess that sound pretty much as the problem described.

Yesterday I have taken out the pin a bit and used aluminium foil to enhance condition. Waited till baterry was empty and the phone shut down. The I took out the batery and pressen "on". Then had it like that over night, added bettery and charged it without touching the screen. It still does not function, not a bit of progress.

You write that I should just wait 2-3 day's (if it is really this problem). Should I see slow progression over the day's or does it function like normal suddenly within 2-3 day's?

Are there any other things (software) that can help this problem or problems with similar simptoms like I (we) experience?

Btw, I do not fully understant all for clear. Why should the screen ground to the cover? Is the cover grounded to/by me? What then if I wear rubber shoes or just touch that ground pin when starting? Probably a noob question but just out of curiosity :-)
[HTC Sensation] subbase:
arggg touch is not functioning for a period after each (yes each) phone call. Even when I have "sleep" to "never" so it's not locking just the touch does not function just like when I would unlock.

Still the same problem you think :D
[HTC Sensation] reelxeno:
I have an asian Sensation. I once nicked a part of the digitizer's ribbon cable located up top of the screen while trying to clean off bits of gunk stuck between the screen and the black plastic border. The touch went iffy and had deadspots.

I went to a local phone repair store to have the digitizer replaced. There was only one digitizer left in stock and went ahead to proceed with the replacement. After an hour of struggling of removing the screen and LCD itself, we found out that the touch wouldn't work perfectly, exhibiting the same symptoms that some of the users here had (touch wont respond well after turning off the screen, would work fine after a couple of touches). As I looked around his store, he had Sensation XE digitizers on stock, and had him try it on. Damn thing worked perfectly.

Just sharing my story with regards to Sensation digitizer compatibility woes. I hope this helps other users here.
[HTC Sensation] subbase:
Hmm, does it still work after a couple of weeks?

I have a sensation as well maybe worth a try to install the xe digitizer but why should I expect it to be better if it is thought to be a grounding problem?

I seem to run XE software, that's not a problem?
[HTC Sensation] zmfl:
From what I've learned, digitizers are prone to failure. And digitizer issues are somewhat similar to grounding pin issues.

Also, I believe XE's digitizer is identical to ours, but with red tint. Actually that's the definition of the entire phone... While the difference in XE/non XE Android Revolution ROM is just the Beats plugin :)

Anyway, it sounds like you did everything correctly. Now just keep charging the phone without touching the screen.

It should go back to normal soon :)
[HTC Sensation] subbase:
grrrr still no improvement. to be sure, I can use the phone but need to charge without using the screen. I do not have to put in on cherger for 2/3 full day's? Think I just order new digitizer :o
[HTC Sensation] antiwire:
I was about to buy a new digitizer and backcover

Hello guys,

I was about to buy a new digitizer and backcover but this guide saved me the cash. Thank you for the tip about the spring contact and pad. I actually like the design of the Sensation 4G and its removable back cover because it lets you easily replace a major component of the phone without removing screws. However, this design can lead to the issues you've helped resolve.

Props for this. thanks again.

With that in mind, does anyone have a pinout list of exactly what the other pads/spring contacts are used for?
[HTC Sensation] zmfl:
Charge whenever you like, just don't touch it.

It should be better by now...

If I remember correctly, you have that bloody silver pin and 3 pairs of pins that are for 3 antennas. The pair on top is for WiFi, the one below is for GPS and the one at the bottom is for GSM.

If you like modding I recommend you add some aluminium foil to the WiFi antenna :)
[HTC Sensation] Eddyliu:
I fixed my Taiwan version device following your suggested solution, better smooth using feeling on Andriod2.3 rom, but still no any response on ICS. The serious problem with Sensation XE device as following, I need your help and it is appreciate that you give me the favour.

At first, the unlock ring and four touch keys not function when calls incoming, I rebooted the device again and again, the screen and keys not worked anymore except the power button can lock and unlock the screen...

After that, I flashed the TW ICS RUU, the screen still no any function...

Lastly, I flashed the TW Andriod2.3 RUU, the unlock ring, screen can be slided and others function seems work this time, except the up and down slide, left and right slide performance is not smooth as normal I feel before.

Is it the screen problem and should it be replaced with a new one? Or caused by other hardware problem? I don't know. Would you suggest how can i fix it?
[HTC Sensation] MrMessi10:
Touch screen issues only apply to me when im charging with original HTC charger.

When i use a different one, random one at a 1$ dollar store or something, it works just fine.

So for me the issue is the bad charger from HTC.
[HTC Sensation] zmfl:
Try a different ICS ROM/kernel. And if it doesn't work properly, try charging without touching a few times again.

Funny, it's usually the other way around :)
[HTC Sensation] razhasnain:
this trick works 4 me and u guys.
[HTC Sensation] Piplos:
I have to NOT touch the touchscreen whenever it's charging

in the next 2-3 days

, or I must

NEVER

touch it while it's charging?

By the way, this guide worked for me, but only for the first full charge.

Then I charged again. This time the sensation was powered on and I didn't charged it fully. I didn't touched the touchscreen, but now I have that issue back. :mad:
[HTC Sensation] zmfl:
Not to touch only the first few days.

The slightest touch can mess it up... Try again :)

If it doesn't help perhaps it's the digitizer after all.
[HTC Sensation] vasujahagirdar:
hi, every body.

does touchscreen issue occures only with custom rom devices??because i have sensation and wildfire,and 2htc chargers when i connect my sensation with one charger issue comesup,but with other charger it behaves normally.and the wildfire doesnt have any issue with either of them.

????
[HTC Sensation] zmfl:
ROM has nothing to do with it :)
[HTC Sensation] undercover:
What zmfl is saying is that is hardware not software issue, and clearly so in your case.
[HTC Sensation] vasujahagirdar:
Than with the one charger My sensation behaves abnormally,where as wildfire normally,with another charger both behaves normal,why so ?plz help.
[HTC Sensation] klausel:
Worked for me thx
[HTC Sensation] g1user101:
hey guys touch screen doesnt work at all. i cant use it at all. the foil thing didnt work, and the pin already seems loose so i dont want to push it out more. im starting to think its the digitizer, but when i plug it into a charger, the touch screen works perfectly. any help?

edit: i pushed the pin in and it works now. but are there any ways that i can secure it to stay there?
[HTC Sensation] beactivelife:
sensation digitizer question

I have a question about the replacement of the digitizer. I have replaced the digitizer successfully 2 times on the HTC Sensation 4G. The screen is very responsive and works great. However, the 4 buttons on the bottom of the digitizer do not light up (home, menu, back, and search). Also, I have to press directly above those buttons to get them to work/function. When I press onto them, they do not recognize me pressing them.

Is there any way I can order a new part, I am not sure what it is called but appears to be a ribbon that sits underneath this portion of the digitizer? Any help would be appreciated, thanks
[HTC Sensation] zmfl:
Perhaps put something under the pin... This crossed my mind a while ago, but I still didn't get round to it. Wasted enough time on this pin as is...

It will bend back at some point unfortunately.

I personally never messed with the digitizer, so I can't help you. But there must be online tutorials or something.

Perhaps you just didn't connect it properly...
[HTC Sensation] beactivelife:
thanks

Thanks, but the digitizer ribbon connects on the opposite side of the phone (top portion). If it wasnt connected properly, the digitizer would likely not work at all. Everything functions like new except for the 4 bottom buttons, you just have to press above each button and they do not light up
[HTC Sensation] Eddyliu:
It doesn't work perfectly, it still work under Gingerbread only, and the screen slided operation is very stuck except quite smooth on 4xt recovery. Besides, Now my device the lower half part screen get hot unbelievably often(the upper half part screen is normal), along with the screen getting hotter, touch operation is abnormal like finger is long pressing.

Do the all above issues due to digitizer problem? Should I replace a new one?
[HTC Sensation] DigitalSnow:
Thanks

Wow, I did not know that such a simple ground pin would have such an effect on the screen.

My screen was having an issue where I would press the sleep button to wake the phone, but the screen would stay dark. I could drag the ring to unlock the screen and then the screen would turn on. This has fixed this issue. Now the screen turns on immediately when I press the sleep button.

Thank You!
[HTC Sensation] veeny101:
This works.
[HTC Sensation] degraafm:
Ok,

Still having problems with my touchscreen.

I'm pretty sure it's a software issue.

I had a similar problem a couple of months ago:

After a Facebook update a pop-up message said: android.process.acore has stopped ( and so did my touchscreen)

I brought it back to the store I'd buyed te phone. They sended it to a repair-center, but when they tried to figure out what was wrong,

my Sensation worked properly.

So their conclusion was: NO defect.

I thought they were right, because everything worked fine, until last week.

Same pop-up after the last FB update, found out it has something to do with syncin' the contacts.

Now: I got a new ROM (CM9) but it still doesn't work.

But, I'm still able to make a printscreen by pressing vol-, power and return button (the red one at the bottom of the screen.

So my conclusion is that my touchscreen didn't died, or am I totally wrong?

I really hope that I'm right and that the options in the fp helps me out.

**Fingers Crossed**
[HTC Sensation] Krayvon:
nice

AWESOME!

Thanks for the fix.

This is what XDA is all about, share the love and knowledge with everyone!
[HTC Sensation] thephenom696:
could anyone help a noob out? :(

What do I have to connect and where?

Wtf this makes NO sense at all, you just put 1 side on the battery and another side on the metal frame inside the phone? :s

I'm Desparate to this issue in my phone :C

I bet no-one will ever read this comment

I'm having the same kind of issues on my evo 3d, touchscreen unresponsive while charging..

Is there any way to fix this on the evo 3d? :s
[HTC Sensation] zmfl:
From what I can see Evo3D has a different "grounding" system. There is no pin.

So it can't be fixed this way.
[HTC Sensation] undercover:
Could you take a pic of back cover and back of the phone without cover please?

Do you use original charger?

[HTC Sensation] Murtagh92:
I have this issue (picture) while charging and sometimes when I'm playing or surfing (when the phone is too hot, I think). The multiple touches are ever on the same line. What procedure can I try? Thanks.
[HTC Sensation] PsicheAlCubo:
Just got my brand new Sensation, excited like a child I opened the box a few hours ago, put it to recharge....and tried to restore my backups: alright here the touchscreen problems started :-/ and NOT only related to the unlock screen but generally the touchscreen of my unit is a mess...now I'm waiting to finish the first charge to disconnect it and try all the solutions proposed.....& I just pray that someone will work out cause I'm freekin out :-/

---------- Post added at 07:24 PM ---------- Previous post was at 06:35 PM ----------

Ok...I unplugged it at 99% cause I was exploding and indeed must have been some sort of current leakage cause now the touchscreen seems pretty responsive...

This is no good news though to me, cause I bought on purpose the Gum Pro (its basically a larger battery) to be able to charge it on the go....but if I can't use it while charging...where's the point?! :-/

Will wait a couple of weeks to see if it goes away...in the mean while could you all PLEASE run this test: put your Sensation to charge and test the touchscreen response...in particular the issue show's up if you browse through your contacts this way:

1- Open "people"

2- Scroll down "quickly"

3- Hold suddenly ur finger on the screen WITHOUT a move: if you see the contacts micro-moving under ur finger...then u have my same issue!
[HTC Sensation] zmfl:
That's just one of the questions nobody has an answer to... :/

Pull the pin out and try doing those four steps I described (disscharge, battery pull, etc.). If the screen gets back to normal after a while you will be able to use and charge normally :)
[HTC Sensation] PsicheAlCubo:
Actually I was thinking to test it another couple of days and then to sell it. I'll surely try all your suggestions, & I can't tell you how much I appreciate all your efforts guys. I just can't understand, & I barely can accept to have a device that cost around 600€ with THAT kind of issues....

I always was and I still am an "HTC fan-boy" ...I still think that Android is the best choice for me as I always like to experiment and to try new stuff....but on one thing the damn Apple wins over and over again: if we forget the last death grip thing (ok..that was a big one...but be onest: it was the only one in ages too...) its products maybe limitated & overpriced...but they do their job damn well....!!

OK...maybe I'm just a little too frustrated and tomorrow will be a better day...we'll see.....

Anyway: I downloaded a touchscreen tester app, and definetely: I don't have ANY issue, even multi-touching with more than 2 fingers, when it's on its battery, but if I plug in the charger........heeeeeeeeeeeeey: you better stay off the guy cause it goes crazy!! I think I'll put a video on youtube tomorrow to let you see what I see....

& undoubtely, this will not be solved with a piece of alluminium or pulling out a pin: we're talking bout a current leakage don't know where that interfear with the touch screen module!!! :-/
[HTC Sensation] PsicheAlCubo:
Ok there is a news: the issue related to the current lekeage seemed to be caused by the usage of a non-htc charger adaptor. I bought this universal usb to ac adaptor from the Cellular Line series because I bought my Sensation in UK and didn't want to bring with me the UK to IT adaptor, which is pretty bulky. But I made a few experiment today and everything works MUCH better, though there is still a little lekeage even with its natural HTC adaptor. The issue completely vanish instead when I use the Gum Pro portable recharge battery which i mentioned before, so I guess this solve much of the problem for me. I'm gonna make a video in a while to let you see what I meant!
[HTC Sensation] ranster:
Yes! i sold it yesterday and went back to my DHD.

Problem solved! :)
[HTC Sensation] Tagini:
Nice! Thanks!
[HTC Sensation] zmfl:
I think there already are videos of the problem on Youtube... You can take a look at them and see if you have the same issue :)

LOL. That's one way of fixing it I guess :D
[HTC Sensation] PsicheAlCubo:
No, all the video I saw were related to the "unresponsiveness" of the touch screen...my problem is not exactly the unresponsivness, but the instability of the touchscreen while in charge..!!

It's definetely a current lekeage, and it's shawn pretty well from the touch test app I downloaded from the market: everything work smoothly when the device is on its battery, but when I plug the charger in...it goes crazy: holding ur finger on a steady point, like holding a button, it's rather impossible as the touchscreen keep thinking ur jumping from a place to another...

I just have to figure out how to hold the camera in the right position to make this video and shaw you all the problem...
[HTC Sensation] zmfl:
It could still be related to the pin. Just try the fix, it takes about 30 seconds to do it :)

If not... Swap the phone... HTC seems eager enough to replace them :\
[HTC Sensation] glenwild:
Nice piece of troubleshooting and bound to come in handy soon.
[HTC Sensation] Michael_Mcr:
Electrically conductive paint will do this sort of job well and is safer and easier to use than a soldering iron.

Also, on my Sensation, i managed to slightly improve the 3g and the wi-fi reception by CAREFULLY using a micro screwdriver to GENTLY bend out the gold pins on the phone body and on the battery cover so they make a better contact. I also cleaned them with Isopropyl alchahol and got a suprising amount of black crud off the pins.

I have to say i have had no problems with the touchscreen responsiveness, tho it is currently in for repair for a fan shaped spray of dust particles under the screen which was getting worse by the week.
[HTC Sensation] zmfl:
Nice, I'll add it to the OP :)

[HTC Sensation] ayyu3m:
HTC shud celebrate the whole existence of XDA forum. There have been so many fixes on almost all the device ever released by HTC. And let me say to HTC, this is why other manufacturers are still scoring ahead of you. Because you make the mistake of releasing your products in a hurry and do not give enough time to THOROUGHLY test your products.

IF ever HTC decides to sue, we shud all go on a mass parade on the internet to show what XDA has done to fix their faults.

And M$ dont be too soon to smile, cos XDA has made ppl put with your blunder mobile OS for years by giving more glamour and appeal to the OS.

[HTC Sensation] Murtagh92:
Last night I charged the phone as it says on the guide. No change, same problem during charging. Now, however, I found that putting a small piece of aluminum foil on the pin, a small but high, when the phone is charging the problem goes away. The only issue that does not disappear is the strip that does not work on the right. When it happened the last time the problem of the strip was resolved by itself after 15 min. This time has already passed a day. Any advice?

EDIT: After some testing I realized that my problem is the pin accumulates too much power, and putting the aluminum discharges.
