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

Camera.exe keeps disappearing

Can anyone tell me what's going on with my XDA2i pls. It's been very stable for the past 6 months which is the last time I Sprite backuped. But last week the camera disappeared and Windows media player appeared on the camera button. So I thought I would re-install the ROM then restore from the June Sprite backup - remember I have been using the camera which must have been on that backup.
After the ROM install, the camera is there and working, but if I try to then do a restore from the Sprite backup, the camera is removed.
Thanks
Mike

search it at here, im sure you'll find any camera software to install....
if you need something great camera application, try CoolCamera at www.ateksoft.com
you can do it! Mike!
thanks

Thanks Clustered .... I will definitely try that camera app, - does it improve the quality of the images (I find them much worse than the supposedly poorer camera in my old XDA 2)
I have since discovered that the camera app is not being removed (there are still 4 camera related files in the Windows directory), but all reference to these are being removed somehow, so that the camera program is not visible in the 'Programs' section, nor is it associated with the camera button on soft boot.
I have temporarily got round the problem by placing the camera.exe icon in the SPB Today function, so at least I can get it started with the stylus
Any clues .... should I be looking at some registry entries.
By the way .... ironically I would like to reprogram the default for the camera button to scroll-down which I use in microsoft reader. Do you know how I could do this (tried Vito button mapper yonks ago but it seemed to cause quite a few problems)
Thanks
Mike

I had this, do you find the battery is discharging at a quicker rate??
The history with mine was it lost the cam function swapping to WMP on the button. Only way to cure it was to hard reset.... of course it would go and do the cam fail just when i had got everything set up and running nice for a few months. I found as it went further down the line that using the back up i had would instigate the cam error quicker than if i didnt.
It started to do it more and more. So i sent it back, they said all fixed. of course it wasnt 'cos the internal battery had discharged thus doing a hard reset clearing the error
Finaly on the 3rd return they did a board swap... which meant i had to get tomtom to re do the activation codes for me.
Load of hastle but it hasnt been a problem in 3 months now.

Aaargh ! yes that's exactly what's happening - battery running down quickly, so I just ordered a coupla new ones (fortunately didn't pay the O2 price of £39 and have ordered from Hong Kong at about a fiver).
Sounds like it isn't worth me returning it to O2, as a board swap would cost a lot - it's 13 months old now
Interestingly though ..... a hard reset puts it right, but as soon as I restore data and programs from a Sprite backup, the problem is back. And yet the Sprite backup was done back in June when I definitely wasn't having this problem. And an earlier backup does not cause it. Does it seem possible that one of the applications we are using has a time -related problem? Only thing I can think of recently was the British summer time auto correction.
Thanks
Mike

dont worry bout it being 13months old they got 2 yr warranty!!!! get it down to them now. you will get it sent off, if they dont replace the board, call the number for the repair company as soon as you get it back, tell them its doing the same (as you can tell from my post before the prob clears n they just turn it round) they send you a package and you send it off as a bouncer, give then a fault report, they will swap the board.
make a note of all yer device info, imea, mac address etc. to confirm the board has been replaced.
i put a pen mark on the warranty void sticker under the battery covering the screw to see if they went inside.... they didnt the first times it went back.
if you have tomtom you will need to scan n send them a copy of the board change document to get your codes reset, also send them the device code tomtom gives you when you try to run it. they require that. it took them about 5 days to sort out at tomtom
You know what gets me about this place is i could have just said send it back but i prefer to give folks as much explination... like i would in return.... unlike i have had on posts ive made where folks have said post it in the right section etc.... not telling me where or assuming you understand all about reg editors or rom changes..... following link from page to page is so frustrating... sorry rant over now
hope you get it sorted soon.,... wish i could get my Q's answered.

Thanks mate .... I'll do all that. Fortunately I can afford the time, as I've got a couple of working XDAII that two of our guys ditched in favour of execs, so I'll just set one of those up until they sort the XDAIIi
Thanks
Again
Mike

Me too
Hi Guys
You have described exactly what happened to me. I use a Motorola BT head set (820 I think) and the tom tom navigator 3 with BT satelite reciever.
I gave up in the end. It seemed to be due to the BT stack or somthing to do with the Tom Tom BT drivers. I have 2 xdaIIi's and I now use one as a gps only (does not even have a sim card) and the other one as a phone (with the Motorola head set) I dont have any problems.
If I try to use two BT items together..... with in about one week the moment i loose the camera and the battery lasts about 6 hours from full.
If I remember correctly the head set would stop working or lock up the phone, you then have to do a soft reset then the camera goes etc etc.
I can tell you I am absolutley fed up with BT I am yet to come across a BT anything that works first time every time. Even if it does work today, tomorrow who knows if it will work. The reason i am looking athe postings is because my new £400 Garmin Nuvi 660 wont connect to the XDA!!**!^%$!£"
Any way best ot luck, you are going to need it.

Hmmmmm .... don't think it's bluetooth, as I don't ever have it switched on - I prefer to use the bog standard handsfree speaker kit and don't use GPS/TomTom.
Plenty of things lock up the phone though :-(
I've gone back to my XDA II and ya know what .... I prefer it. The quality of colour saturation on the screen is much better - OK it's not quite as bright as the XDA IIi but the latter is not really any good itrself on a bright day.
.... and the camera in the II is just a gem - OK only 640k but the way it renders the image is just like silk compared to the naff camera in the IIi
... and I'm not really gonna miss the wifi, and I never really bothered using IE in landscape.
So I think I'll stick with the old II and see what you guys think of the Orbit (?) when it comes along
Mike

Well.... great service (eventually) from O2. They sent me a replacement without even waiting for the faulty XDA2i. Bad news is they sent an XDA2s ....but they then sent an XDA2i the next day. It's not brand new but presumably it's been 'reconditioned'.
Charged it up, did a hard reset - camera was there OK. Did a Sprite restore from a known good time (last June). But camera had disappeared again
I guess it's remotely possible that they have sent me the one that Richard (?)returned but I think he said they'd definitely done a board swap on his.
Despite the good advice on here, I'm still inclined to thhink this may be a software conflict problem rather than a hardware issue. And somehow it seems to be connected with time. I had not installed anything new when I suddenly lost the camera about 3 weeks ago. I'm restoring from a Sprite backup that definitely was not displaying any problems when I made it.
Regards
Mike

my cam issue would come back if i used a restore from a good point too. But that was on the old board. Ive just done a full clean install of everything and its seems to be ok. I did wonder is some gimp out there had writen some kind of virus that i had got somehow.

It might be the startup programs/services...
Try checking the Camera_Detect.lnk if it's functioning normally...
Although I'm really not sure if it is the cause but I have a similar problem but not with the camera...
Rather, it's the rotatescreen icon...
I hard reset and the icon is there but when I have installed programs it disappears once I soft reset... not sure which of the programs installed overrides the icon startup...
But I think it's during the startup that somehow make these services (camera, screen rotate, etc.) fail to run because some of the programs might be clashing with them on startups/bootups/soft reset...

I think you might be correct, as the replacemnt XDA2i that O2 sent displayed exactly the same problem when I put all my stuff back on it, but after another hard reset I put just a limited range of utilities back on, and so far in a week or so, it has been faultless
Mike

my diamond is crazy!!! Help!!!!

from several days ago whem i touch in diamond icons never select the one i touch!!!... It selects the icon on left or right but never the right one....
When i have a phone call i select the green icon and it turns the phone off
What can i do?
I aligned the screen thousands of times, i installed the different calibrators and nothing.
I align screen, it works well for a few seconds and becomes crazy again. I soft reset, a tried everything i remember and always the same.....

Obvious question: Did you Hard Reset?

Try a hard reset.
If that doesnt work then it sounds like the screen is screwed, get the unit swapped.

I've just installed a new rom! I think i have to swapp the unit
The problems are the same. Anything more i can do??

If you just installed a new ROM, did you do a hard reset? To me it sounds as if the calibration for the touch sensor is off. The first thing that you do after a hard reset is calibrate the screen.

So you can try to calibrate the screen, bofore doing the hard-reset.

You can but when you hard reset you just have to do it again

Also, you could check your local optician for any additional problems.
No, but honestly, a hardreset and recalibration should fix the problem. I'm aware that GNes/GSen can give some problems if it thinks it has rotated the screen, but I've never seen that occur outside programs that don't rotate the screen by themselves.
If that doesn't work, Sync it, back it up, whatever you want to do, possibly flash to stock and return it to whereever you bought it/HTC to get it swapped.

thank's everybody... I tried it all and the same. Going to swapp

have the same problem.. it wasn't there before, had the phone for 3 month.. i think it has to do with water under the screen, used it in the rain and then it began to behave this way (due to the big speaker hole maybe?) , it works fine otherwise! Any idea how to fix it? waterdamage? - guarantee or what?
I think it´s wierd if you can´t use it when it´s raining..?

How many phones can be used risk free in rain?

i don't think that's the problem. no water in my phone, rain or other....
i think it started after gsen installed...may be wrong, or else or.....

Very little chance Gsen having anything to do with it. Many people are using that (including me) with no ill effects.

Hmmm, I though I was the only one with this problem. I'm on the second unit now, the first one always do soft reset by itself after every few wake up. Now the alignment always gone off after few minutes of use. I'm waiting for the replacement unit now.
Initially I thought it was because of the ROM update I did, but even after I restore the original ROM, it still happen.
Looks like I'm quite unlucky with the Diamond .

problem solved!!!!
gone to look for assistance.
After 3.30 hours new touch screen and they sad to me new components inside.
For now all good. Till when??....
hope it was the last problem

So its a guarantee issue? - bad components inside?
It still works ok, so i wait to send it away..

till now all ok.

Tilt no longer enjoys being touched.

So, i'm usually quiet on these forums. Just reading, trying roms, etc. But here is something that has me stumped. Last thursday my phone crapped out. When i woke up and looked at it (it was connected to my laptop/charging) Applications were opening left and right, i couldn't close any of them because stuff kept opening. I tried to soft reboot it and it didn't help. Once it rebooted stuff started opening itself at random again. I ended up pulling the SIM and battery out and leaving it for 5 minutes. When i put it back and powered it up the touch screen no longer worked, but apps weren't opening on their own.
What gives?
I have hard reset (which means it's waiting for me to touch the screen to setup my rom), i have also taken off the screen protector (in case it had something stuck under it. Neither of these things helped. Per the forums I got a new screen, just put it in, and the touch screen doesn't work still... I'm drawing a blank here can anyone give me some advice. Going back to my Prophet for the time being but I HATE not having a keyboard (and it's slower than molasses)

have you tried flashing a new rom via sd?

Check that the screen protector has not moved under the front bezel and keeps pressing your touchscreen.
Robert

I have totally removed the screen protector and even replaced the screen for that matter so I dont think that's it. I haven't tried flashing a new rom. I just found it odd that this has worked for so long and now I get what appears to be hardware problems. As for flashing Via SD memory, is that better than doing it via cable for some reason? I'd be willing to give it a go...

Any other suggestions?

Similar problem happened to my Kaiser phone, although no multiple files opened, the phone just won't react to any touching, not stylus pen either. So I first soft reset, then hard reset, none of them works, now the phone can Sync alright, but the screen just stands on the Window Mobile screen, saying "Tap the screen to set up your window mobile device"
I only have this new phone for <3 weeks.
I went to HTC site, want to download a latest ROM file from them, after typing in the S/N, it won't let me, saying that ROM is not suitable for my phone.
So now I am download ROM file from this site, will choose one to flash the phone, see whether it works.
I will call HTC tech support tomorrow after Thanksgiving, see what they suggest
Hope some gurus here can also make some suggestion, Thanks!

Well I replaced the LCD and the new LCD works great, but the screen still doesn't respond to touches. What gives?! I hard reset and I got past the windows screen alignment thing by creating a welcome.not file but it's still pretty much worthless w/o a touch screen. Anyone have any suggestions?

Whoa, i thought something odd was going on. Never mind i got entirely the wrong idea.

Ha, not the case.
Anyone know if a flex cable would fix my issue? I dont really know what the felx cable is for but i've seen posts about people replacing them w/ LCD problems. I don't know if it is touch screen related or not, and i'm kind of tired of buying parts that don't fix my problem

please just flash a new rom whch ever you want (for some reason i thought you said that it keeps restarting your device because if that was the case the only option you would have was to flash via sd as activesync would load long enough for you to get a connection to flash from the computer)..trust me just try it..what have you got to lose

I reflashed one yesterday actually. The newest HyperDragon (which is looks like a new one is available today) It wasn't rebooting but initially windows were popping open left and right so i restarted it a couple of times(which i first had the problem, not yesterday) Yesterday it worked like any normal rom w/o the ability to touch. Anywho, after the flash of a different rom. No luck. I'm thinking it's a hardware problem of some sort but as i've already replaced the LCD i have no idea what?

yah thats sounds funky..you can bring it in for a warranty exchange either at a local DSC or over the phone (that is if your with att) and if not call HTC..all devcies come with a 16 or 18 month warranty

Well I called ATT yesterday, apparently I purchased the phone On Oct 17th 2007 which means It's out of warranty (apparently it has a 12 month warranty?) So it sounds like I'm SOL. So, i guess I'm off to ebay to try and fine a phone that I can canibalize to try and get mine going again.

touch screen
this may sound dum but when you replaced the screen did you replace the touch part as this is different from the screen

Well I picked up this
http://www.blackberry8100parts.com/...B3-NEW-HTC-TyTN-II-KAISER-P4550-_p_35-70.html
which includes the digitizer (from what I know it's all one part when they send it to you) The screen has the digitizer built in. So i replaced the part they sent me.

I just stated having this issue. My touchscreen stopped responding to touches over the weekend while the keyboard was extended. I just took the phone apart to make sure everything was connected right & put it back together, & now the touchscreen doesn't work at all. This sucks!

Any news? i'm having the same problem: no response at all, stuck at "Tap the screen to set up Windows Mobile-based device"

An interesting problem with screen
well my tilt fell out of the car holster while using gps and i suspect the screen hit my gear shift. I didn't notice anything odd after i put the battery back in it (yeah it fell that hard lol). Later that night I went to check mail and noticed something not right. Turns out my screen seems to have been pushed in a bit. Well here's the issues I've noticed so far: All the touch responses seem fine except for 1) the screen alignment doesn't register taps, but otherwise the touchscreen works and 2) on the htc home screen, I can't tap the house icon unless I tap any other icon first.
Initially I thought there was some pressure or deformation right at that particular spot, but it reacts the exact same way in landscape mode. I can't tap the house icon first; I have to tap something else first, then the icon works fine until I open a program or something and go back to the home screen. Then I simply have to tap weather or something and then home.
I'd reflash the rom or do a hard reset, but the screen alignment didn't work when I tried it so I didn't want to get stuck at the "tap your screen to begin" part.
Any ideas or do I just need to buy another screen or maybe just the digitizer. the amount the screen seems recessed is maybe a millimeter at most. Just enough so that I noticed a difference when touching contacts just above the housing. I tried cleaning by using a business card and running between screen and housing. Ohh... and one more thing... when I open the cube and then close it, I get what I refer to a static frazzle for split second and it goes back to normal. That only happened a couple of times after the business card thing. Do you think I just loosened a connection? damn... I still haven't taken it apart yet. Think I need to. Any help appreciated.

If your screen does not work, you can still use your phone. There is an app that you use on your computer that acts as the touch screen. This also works when the screen craps out.

yeah -- my touchscreen didn't crap out totally, it just got muffed up when I dropped it a bit. Well, i went ahead and installed codefreaks remote screen alignment thing and did a hard reset. Well, the hardreset did the trick w/out the need for anything else. The alignment worked and everything. So, i'm back in business. Everything seems to work properly, except that my screen is still recessed a tad; but, that's not a big deal really.

[Q] Wifi not turning on

I bought a galaxy note n7000 from a friend. It has android 4.1.2 installed. build number is n7000XXLSA.
the problem is wi fi doest turn on.I mean whenever i want to switch it on it seems its trying to get on but fails. The green light never shines on it.
The problem i cant understand lies with hardware or software.
Sometimes the wifi gets connected and then it works like a charm. But most of the times no matter how hard i try it never gets turned on. Ive tried factory reset, restart, removing batter and memory card nothing seems to work. I tried wifi fixer app but nothing happened.
I am not very technically aware of rooting, and how to modify it. But i think from what ive learnt is it is caused by updating from ICS to jelly bean 4.1.2
I dont know whether my phone is locked or unlocked, rooted or un rooted cause im totally new with phone.
Please someone guide me how can i rectify this problem, I dont mind taking risk with my phone but wanna know what all should i do to solve wifi issues.
Plus i also would like to update to 4.2.2 kindly let me know step by step starting from basics how should i go about it.
regards

Go to settings and wi-fi and there when you turn on the wi-fi it should show the your network which is remembered and show read something as authenticating obtaining ip addreas and such.. Just select your netwirk once and click on forget and then try to connect again putting in your network key.. To check if you are rooted or not: you must have an app which saya superuser or su.. You can also download root checker app from market to see if you are rooted or not..

Solution found
sorry for the long post but this will work
After three months of dealing with the same problem on my GT N7000 as nashbloom i have found a fix to this wi fi problem.
And I mean WIFI problem. this is not a matter of obtaining a connection, this is a problem where the wifi wont switch on at all.
It trys, to switch on (sort of transition phase) than freezes or fails and turns off again.
Just as I was preparing to back up my phone and take it in to samsung the next day I found a post on a you tube clip saying to clean corrosion built up on wi fi antenna.
Desperate, I tried it,
1. remove 9 screws (dont worry they are all the same size) on back and remove cover
2. with a cotton tip/bud wipe corrosion in top left hand corner (looking at the back of the phone)
3. not knowing what a wifi antenna looks like and having seen no corrosion i wiped everything including the cover.
4. i removed a few connectors and put them back in place.
5. put everything back in place and problem was instantly fixed
I did this two days ago but have had one time where the same problem reoccured, otherwise, perfect.
P.S. This is proof that this is a hardware problem not a software one, but i kind of knew that when i changed every wifi setting on the phone several times

will try these today
I will try these today as soon i get home.. i been looking around for a fix.. I hope these will resolve it

Two months now with this silly wifi issue. Did this trick help with your phone?
I did everything possible trying to solve this problem but to no avail.
Wiped anything that could be wiped on the inside, replaced the USB port board, but wifi is relentlessly disconnecting at random times.
Any idea?

I found something weird.. when the phone is without the back cover wifi works perfect. when I put it back the wifi goes off. ???? I really do not know was wrong with the phone.. (i do not use it anymore).. the only guess is that the back cover pressure something to the board and disconnect the wifi.. I really do not have a explanation.. take care..

Like everyone here, I was having the problem with the greyed out WiFi and also got some practice with flashing firmwares and doing factory resets, backups and restores, all in vane.
I found this post and decided to give it a try, also checking a YouTube video about how to open the GT-N7000
My phone did not have any corrosion, but after reconnecting, i.e. taking out and plugging in again, all connectors to the main board, the WiFi came back to life. That was two days ago. I cannot say it works like a charm, after a couple of hiccups, I just don't trust this phone anymore and I think I had the greyed icon once yesterday when I tried to switch off and on the WiFi.
This experience led me to believe that there is something with the connectors that got loose after my phone has fallen off my pocket a couple of times. If you wear pants that were not designed to carry phablets, this might happen to you as well.
Anyway, a big THANK YOU to atchya for the idea of opening the phone.
Cheers,

Yeah above solution works. This Is the only way I got my wi-fi to work. Tried re-flashing Rom (downgraded and upgraded) even re-flashed Radio. Finally cleaned up , unconnected and reconnected cables, so far works fine (no greying out of menus etc.) . Will keep you posed
edit: Open the photos in different tabs to see the antenna connectors, they are tagged you will know exactly what to clean
