problem with touch screen, can't click on anything

i just recently bought my xda2s and it worked fine for a week though. now, from time to time my screen would be "untouchable". literally i cannot click anything or open anything even if i soft-reset it for 10x. buttons seem to work fine but the screen does not. it happened twice while my bluetooth was "on" and i thought maybe it was the bluetooth but recently the same thing happened with my bluetooth now turned "off". i have to wait for hours before it would return to normal again. Anybody help please? By the way, my bluetooth version is 1.0.0 build 3500.

I had a similar problem on my Samsung SPH-i700 PocketPC Phone through Verizon Wireless. Even after a hard reset, I couldn't get past the screen calibration, until I found out that a piece of hair and debris found on the outer edge of the screen right under the lip of the cover was interfering with the touch portion of the display. Apparently, the touch sensors extend past the visible area of the screen, so with both a little aircan and vacuum cleaning, the debris was picked up and the touch screen functioned normally again.
Is this a consistent and/or intermittent problem? Did a hard reset resolve anything?

look for the alignment

Do you have Calligragher 7.4 installed? I read about this in Tekguru website that if you re-install 7.3, the problem goes away. That is what I have done and it seems to be working for me so far (2 days test).

i've checked out my screen and i dont see any dirt or something... i even have a screen protector... dont know if that might cause the problem. Same thing happened last night but this time it was just for a short period of time then it went back to normal... I didn't try a hard reset cause i dont want to loose some of my files but if ever it happened again, i might try doing a hard reset and see what happens... right now, im having my xda2s checked if maybe it's a factory defect or something...
regarding the caligrapher program thing, i dont have that...

Hey, i have the exact same problem I bought mine here in Toronto, from an Asian dealer, its the O2 XDA IIs asia-pacific model.
Same problem, screen(touch screen) goes dead like no responses to any touches, for like half hour - 2hour once in a day or something and nothing cures it, hard soft rest nothing. just with time it suddenly starts working and the Handheld is useless until then...well i dont see any cure and this is the only place i have heard about someone else having this issue, i will take it back to the dealer, in hopes of exchanging.
any feedback will be will be appreciated

overclock it for a few days..that fixed mine..dont know how but it did.

There is a tread in blue angel about screen aliment that you might like to read. seems 4k of devices went out with screen problems.

What is overclock it. Fairly new to this. Mine just keeps trying to allign and thats all it does it doesnt go into boot mode just allign screen all the time

Huge problem!!!

I recieved my tilt from Amazon roughly aweek ago. Everything was going fine up until not to long ago. The screen stopped registering any screen taps from the stylus or my finger while everything else worked just fine. I reset the unit a few times hoping to resolve the issue. Nothing. THEN I made the big mistake of hard resetting the unit. Now i get to the calibration screen and no further. Anyone got any ideas? Any idea where I can take this to get looked at? i was contemplating sending it to Amazon as defective but ive already flashed the HTC Rom to it shortly after recieving it. Am I completely screwed? Help!!

you could try reflashing the original ROM

Yeah, I tried that shortly after making my original post. Still nothing. I'm curious if the cable for the digitizer came loose somehow (no idea how though) or if it is an actual hard ware issue.
I thought something was wierd when it was working though. When I used the stylus the taps were very inaccurate recently. More so towards the upper hight hand corner of the screen. Calibrated it a few times hoping to correct it but it was always slightly off still. Then it just stopped working all together.I thought it had something to do with my screen protector but after removal was still a no go.
Luckily I am still able to make phone calls thanks to the slide out keyboard. Not sure if it rings or anything when I recieve one though. Still stuck at the calibration screen Any other ideas?
What size star key is needed to disassemble the tilt/tytn II? I may try taking a look inside to see whats up.

If you're stuck at the calibration screen after a hard reset, how are you able to receive calls? Surely the reset hasn't completed?!?
Also, if you have reflashed to the original ROM, and thats now stuck also, then it has least got the correct ROM image on the device, thus allowing you to return it for a replacement.
Still a little confused about how you're able to use it at all though...

i honestly though it wierd myself. after flashing back to the original rom. at the calibration screen if i slide out the keyboard, press the talk button , close then reopen the keyboard, it lets me dial out using the number keys on the keyboard.
I can actually make out the home page behind the calibration screen as the screen reorientates itself.
edited Well I've no idea what just happened but the screen just stared working again out of the blue. My dog jumped on the bed n stepped on it ant the cursor moved. Very weird. Damn I'm lucky. lol Thanks for the input guys. Lets just hope it doesn't happen again XD

return it ..

I agree, sounds like a loose connection somewhere

Could be grit between the screen and frame
One of my friends had an XDA Orbit and he had this problem. It turned out it was a crumb or piece of grit wedged between the frame of the phone and the screen causing the screen to be permanently pressed at that point. He used some fine implement (maybe a pin - can't remember) to dig it out. If this was the problem with your phone that may explain why it suddenly started working viz the bit of grit became dislodged by itself.
Cheers,
Ashley

Xperia restarts automatically!

I am facing the problem recently last 2 3 days
my Xperia restarts automatically
sometimes there is 30% to 40% charging left still its shut automatically and never been start.. i have to change new battery
any solution for this or anyway to find the problem?
regards

anybudy would like to answer this please?

I'm having a similar problem...my x1 sometimes shuts down while in the middle of doing something, like opening apps, sliding out the keyboard or even navigating touchflo. I suspect it could be a battery problem, as someone in the forum discovered, having also shut down problems, that his battery is loose and the connectors are not properly met so he stuck a bit of hard paper to fix it, but I checked mine and the battery is not loose. I don't want to spend on a new battery if these shut downs weren't really cause by faulty batteries, so yeah anyone has a clearer understanding on this?

Hi all
I am also having a similar problem the past 2 days and as of now i cant use the qwerty keyboard because just as i begin to slide the qwerty out the screen goes black and the phone need to be rebooted.
I have just changed to Valkyrie 2.4 yesterday thinking that maybe its was software problem with Touch X but the problem still persists. Only difference is that with Touch X the phone would reboot itself.
Anyone else having any similar issues and what would the fix be, or shall i be off to my nearest service provider for repairs?
Thanks

Uhm.. about that problem when you slide it out and the device turns off.. i had that too and i send it in to repair.. it will probably be fixed under warranty, and stock rom or custom rom doesnt matter the problem was still there... and it happend to me 5 days ago..

'When i slide the thing out it sometimes restarts'
I used to have that with the stock ROM so this all might be more software related...

yeah I am having the same problem, No Water Damage btw. i found that if i sometimes in portrait mode if pressure is applied to the top right region, it will shutdown and/or restart. When I slide my screen up to landscape mode it screen is just black. I'm going to contact Sony Ericsson to see what they have to say about this.

It resets when the phone freezes. Sometimes it freezes so bad you have to manual reset.

My phone is doing the same thing but when i slide it up. The screen goes blank and then it restarts by itself. I never flashed my phone so I thought it was a firmware issue. I finally updated to the R3A firmware and lo and behold the same results, but instead it didn't restart, it just turned off or the screen goes blank. I've sent the phone to Sony Ericsson and they told me that I would have my phone back in 7 to 10 business days, but they're liars!!! It's been 13 business days and counting and no word as to whether the phone can be fixed or updates on status other than it's in "work in process". So then I called again today and complained to SE and the result is that they are "awaiting parts and Xperia parts are on back-order". After further probing SE told me that they would call me on Monday to officially let me know what the hell is going and why it's taking so long to repair my phone. I paid $800 usd for the phone and I would expect that their repair service would be a lot better and quicker than what it is! During my wait time for my phone, my PS3 broke down, I sent it in, got it fixed and returned already. That was within a week. There is definitely something wrong I tell you! They just need to send me a new phone!
Sorry about my rant guys, but I'm pissed!!!

My damn phone has the same issue, Until now, this hasn't been repaired for it's crack. And I'm almost out of warranty days, I think I bought it 2md day after the xperia was released. I'll try testing abou the presuure point though. I give you update

I did have the same problem..
Hi... I did have the same problem n I couldn't find any solution... So i send it to repair...

HELP!! my screen works....but it doesnt....

ok guys and gals, heres one for you. i know im a noob but this one has got me stumped and i cant for the life of me find anything in this or any forum or even google. i have the tilt. just flashed a cooked rom for the first time several weeks ago thanks to everyone on here and all the FAQs and stickies. (to any other noob, all the info is out there!!!!! dont be lazy!!! SEARCH AND READ YOUR HEART OUT!!!!) anyway, im running Witscheys latest 6.5 rom build 23071 HSPL 3.34 w/ radio 1.70.19.09. ive been tweakin it pretty much every day tryin to get it to the way i want.
well im so close to finishing and the the screen suddenly decided to randomly not respond to my touch. the buttons were the only way to control the phone. even after numerous soft resets. then it would decide to start responding. so i was doing some research and tried a couple diff methods of fixing "screen freezes" (but i dont think its a "screen freeze" as it worked fine with the use of the buttons) finally found a post in the thread for the room that read:

I had that same problem. Need to change the cache settings in Advanced Config. The filesystem cache defaults to 512kb, so I set it to auto and it doesn't freeze anymore. I also turned up the glyph cache to 32kb. Between the two, the phone interface runs fast and smooth.
so i tried that and it still didnt fix it. then i decided to just do a hard reset and install one app a day at a time (all the ones i had before the hard reset) to see if one of them was casing it. well after the hard reset i didnt notice the problem anymore. i was stoked. now all i needed to do was figure out which app was giving me trouble. WELL about 10 min later when i was texting my friends as usuall, my phone recieved a message but the screen was black. so i slid it open (wake on slide) and the screen turned on. replied to my buddy,closed the lid and the screen went black..... WTF? slid it open, screen on. closed, screen black.... and so forth. this is the way it has been since yesterday. even tried two more hard resets with no change.
NOW HERES THE WEIRD PART!!! if i slide it open JUST A LITTLE very slowly, the backlight turns on barely. just enuf to see the today screen but its very very dim. its as if there is a bad connection. but the screen is in portrait mode like it should be. if i open it fast the backlight turns on, screen shows portrait, then switches to landscape like it should. close it, it goes black but i know it switches back cuz the next time i open it, i can see it change again.
EVEN WEIRDER--- if open landscape, get into an app or program such as contacts where i can flick to scroll, ill close the lid, immediately flick the screen, open lid and low and behold my friends are just scrollin by!!!! the damn screen is responsive but there is no backlight!!! so to test i plugged into my laptop, activated mymobiler, and EVERYTHING works like it should when i touch the screen, use the buttons, open close the lid. it all shows up on my laptop. but the damn screen is still black when lid is closed. so i can literally look at my laptop and touch the black screen on my tilt and controll it!! WHY IS THE BACKLIGHT SHUTTING OFF WHEN ITS CLOSED!!!!???
so then i decided to tear the damn phone completely apart about 2 hours ago, check all connections, and clean all the dust. all connections checked out fine, put it back together and still have the problem. i know there is a magnet and sensor that tells the screen when to rotate when the screen is opened or closed but its obviously working cuz it will rotate the screen. my guess was that some kind of registry entry has been changed somehow. but then i realized thats not it because the hard resets didnt fix it. now im thinking hardware...... IM SO SORRY THIS POST IS SOOOOOO LOOOONNNNGGG but i dont know what else to do. phone was working great up until yesterday and i cant have this!!! has anyone had this problem with this or any other device or even know which direction to point me in??? PLEASE HELP!!! thanks in advance for any replies!!! the quicker ther better

I think your flat cable is broken. Doesn't make connection when closed (no backlight), barely connects when opened (backlight on).
So I think you need a new flat cable...

I agree with blueflame... I think it has nothing to do withthe rom flash.. it sounds like your ribbon cable is "Starting" to go.. unfortunatly it will only get worse where it wont; read you memory card, and evenutally your Sim card as well (speaking from experiance here).... If you are handy with tools, you can try to but a new one yourself and install it... But there are also some shops aroudnthe world, aswell and some members here who may be able to fix it for you... for a price (and not, I am not one of them)... Sorry for the bad news bud.. but I personally would rather knwo that than hard resettign 100 times and nrto beign able to figure out the problem...

hey. thanks for the fast replies! thats not exactly what i wanted to hear but like Teej said, its better to know than messing around with something else. now by flat cable are you reffering to the biggest ribbon cable inside the phone that connects the screen half of the phone to the keyboard half? Or the connector that comes directly out of the screen itself (meaning i buy a new screen and install and all is well) or is it another cable? but i think those are the only two that have anything to do with the screen other then the one for the sensor/magnet. here is a photo to help point out which ones. i have the manual so i can grab more photos if needed. thanks again for the help so far. good stuff. we are getting somewhere!!

[Q] Touch screen dead spots

This may be a problem beyond the scope of android, but seeing as I'm running it, I thought I'd try here first.
I've noticed that the lower left hand side of my screen has a "dead spot" where touch is simply not registered. To illustrate, I went to screen calibration's test screen and drew a straight line along the edge of the screen. (See Attachment)
I've tried recalibrating the screen (manually and resetting to default calibration) as well as wiping data and reinstalling the system. Reinstalling the system worked once, but then the problem came back and subsequent reinstalls did not fix the issue.
I'm running Incubus26jc super froyo [RLS 12] on the 15-07-10 340X480 Froyo Kernel.
Anyone else seen anything like this? As far as I can tell, the problem is not getting any worse. Currently, it's only a hindrance when trying to use keys in that region, but I can work around it by switching to and from landscape. It's a bit of a hassle, so I'm hoping someone may be able to shed some light on the situation.
I was sure it was hardware until the system reinstall fixed it, but am now baffled as I can no longer replicate the fix.
I have not tried reinstalling the kernel but will at some point in the next day or so. I'd like to avoid switching back to WM to check if the problem persists, but may have to... we'll see. Doing everything I can to make this phone last until the Incredible month of February when I'm up for an upgrade.

dont know the issue resolution... but i have the same with my touch vogue.. and in the same 'area' apparently as well.
hard for me to hit the 'a' key on my keyboard. hehe

I'm glad to see I'm not the only one... anyone else?

Bottom right corner for me... I was able to calibrate around it but it took a few tries.

The sensitivity across my screen was inconsistent some time ago. I found that years of my abuse had taken a tole on the exterior of my phone. It eventually got worse and I bought a new housing (with a new digitizer) on ebay for a reasonable price. If it is hardware then it really isn't that hard to fix if you like taking things apart.
If you're sure that win mo accepts input from that part of the screen then nevermind my post. I would play with a painting app though and investigate the hardware further.
I may be talking a little out my a$$ with this part but.. is it possible that in calibrating your screen the os may change it's settings on how hard you have to press and such also. that may be how you got it working.
In any case, my investment in a hew housing was well worth it considering how modern my old phone has become thanks to the developers here.

In my case, no - when drawing a straight line down or across the screen, the line starts 'moving' away from the stylus (like the picture in the OP).

Gah... now it's shutting itself off randomly and the dead spot has grown. Not good at all.

Yeah, mine was better for a while then 'slid' again. I ended up swapping the digitizer with my other Vogue and things are back to normal.
Sent from my Full Android on Vogue using XDA App

I have another vogue, but am weary of doing anything like that. How hard was it to get done?

All you need to do is switch the front half of the housing rather than the digitizer itself- it's not hard. There's a teardown guide somewhere in the forum, Google Vogue teardown and it should be at the top.
Sent from my Full Android on Vogue using XDA App

The only thing that worries me is that my spare vogue exists because it was dropped in a muddy puddle. I'm hoping the water damage isn't too bad. Guess we'll just have to see.

it is really annoying
I have the exact same problem and I too thought it was a hardware issue till I saw this Thread. I was ignoring it till two days ago when it started really bugging me. Now, I don't even need to press any button and it automatically gets pressed around the curve and I have a google search box there, so it keeps on searching for eee or sss randomly and started draining my battery. Is there a proper fix for this?

I thought I'd chime in too... I could never seem to calibrate the touchscreen properly in either Android or Debian. Changing the screen resolution (i.e. msmfb scaling) seems to have no effect, whether it's 240x320 or 640x480. Any area within 5mm or so of the edges of the LCD will register as the edge, making "A" and several other keys on the virtual keyboard impossible to hit. Passing calibration values to the kernel didn't seem to fix anything, but it's possible I was using them the wrong way...

i have the same kind of problem on my Kaiser... i think its realted to hardware... either the housing or the digitizer...

I am experiencing the same problem on X10 mini pro. the same screen spot exactly, i have to try very hard to get z or x or shift to work. Sometimes when I try locking the screen and unlocking it back, it works.

update
so after a very long time with this problem i decided to change the digitizer and problem is gonne. visualy the broken digitizer had nothing wrong with it. The fix was fairly easy though, there is no glued parts involved into getting a new digitizer on the u20i.

Touch Screen
I just bought a brand new Cubot One and it looks more than perfect! It has just a little problem with the touch screen ( I think its the software, need ROM change). There is a dead line on the right side of the screen that touch doesn't work at all. Any solutions? Anyone faced that before? Can I fix it myself or do I have to send it back for replacement? Is there any video or guide that shows its done?
I uploaded a video on YouTube to show the problem but i cant post it yet.. (new member)
You can write "Cubot One touch screen problem" and it's the 1st one.
Thank You!
