Guys, I hope you can help me!
I was using my Imate Jasjar when it was accidentally bumped by another person. the Jasjar fell but it wasn't that high and the floor was carpetted. However, I noticed that whenever i try to tap on the Start button on landscape mode, the calendar application opens up! And when I try to tap V-Bar on the other corner opposite the Start button, the Contacts application opens up. Basically, the soft keys on the bottom screen are the one opening up even if I'm tapping the ones on top! If I tap the bottom soft keys, I thought the Start button or my V-bar would come out but still the Calendar and Contacts applications were the ones that opened. Basically the everything on top cannot be tapped!
On Portrait mode, I can tap the start button but when the V-Bar was tapped it still opens the Contacts application.
I went to Settings then Screen to re-align the screen. I thought it would solve the problem but apparently it didn't! I was trapped in the Align Screen section giving me an endless loop to tap the 5 areas of the screen.
I now did a Hard Reset, and now I'm forever got stucked to the Align Screen part.
What am I supposed to do??? Please help!!!
Hi,
Seen the same problem... Try to guess the error margin of the alignment...
for example instead of tapping in the center of the cross try tapping on left or right... Since your screen isn't aligned you can't press on the center...
Now the problem is hardware, not the MB but the LCD...
After tou figure out the margin error, the Universal will resume and then you ca align the screen via Start->Settings->System, align screen
I'll try to know more about this problem asking my friend.
Best of luck
thanks for your reply!
i also believe that it has something to do with the LCD. there are no cracks whatsoever. problem with the aligning is i have to keep on guessing. and if ever i do align the screen successfully, i'm not sure if re-aligning the screen in Settings would solve the problem.
i would appreciate though if your friend or anybody else can shed light to a solution.
This is a simple problem to solve ;-)
When the allign screen is ON and you have to make the first tap on the crosshair (just before you start clicking away to allign your screen), twist your display from landscape to portrait mode...
Now continue to allign it as usual, and you should finish successfully!
Cheers,
San
unfortunately, after following your instructions, i still went on an endless loop on aligning the screen. i'll try to reflash the rom and see if it would work. i hope it does...
i updated my ROM. still stuck on the alignment screen!
any more ideas?
To be honest, sounds like your screen is broke. Even if you got it to align, I doubt it would be very usable. I think you are looking at repair - if there's no visible sign of damage, you might get away with a warranty repair.
Cheers,
Steve.
Hi
Few months back i've got exactly the same problems (odd LCD behavior, impossible alignment, etc...) with an HP4700. I went to the service center and they had to replace the LCD screen. They did not charge me and take it under warranty. In my case the unit did not drop and i made it clear to them. I would suggest you go back to the service center and forget about the drop in your problem description .
Cheers,
Bruno
I had the same thing happen on a HP 3700, I did not even drop it all i did was install the Quake game for it and after a few days the screen alignment went a bit out. It was usable but definately out by about 1 cm in each direction. The unit had not been dropped. I went into the allign screen utillity and ended up in the infinite loop. The only way to fix was a new screen. But unforunately it was no longer under warranty. The screen consists of 2 separate parts the lcd and the touch screen bit. In my case the lcd had no issues just the touch screen. Very annoying but there you go.
Search your soul and do what you feel comfortable with.
Good luck
Charlie
thanks for all your replies!
i've made several searches yesterday with similar problems (even if they're using different PPC models) and they all ended up sending back their units for repair. there's even one who posted in expansys with the same exact problem!
we'll be sending it back through expansys (we got the unit from them) and hopefully get it back before the end of the month. and yes, i won't tell them that it was dropped, he he :twisted: and they won't find evidence either on the outside because there are no physical damages. what a start of the new year for me <sigh>
right now i'm back using my XDA IIi.
thanks for all your support! this is my first thread/topic in this site and it's so unfortunate that it had to be sort of a negative one. looking forward to be active more here!
Hello there
This might help (I am currently wrking with 200 PDAs so have had this a few times)
THere may be a iece of dust/biscuit crumb etc, under the edge of the casing above the screen, try using a post it note or paper and go around the casing/edge of screen, this should clear the screen of anything that may be causing this problem.
THis worked for me on the majority of non-aligning screens

My story was, one day when I needed to twist the screen, it was a bit stuck so I twisted a bit harder, yes it went back. Then few days later, the mis-alignment started and since then I have been keeping to do re-alignment my screen.
My screen is mis-aligned once every 2 or 3 days or even few minutes then I have to re-align by using WM5's alignment program. It sometimes takes me 2 or 3 times or even one time.
The most anoying thing is it keeps forget after aligned screen.
Now, certainty, I don't think it is a screen problem because after running alignment app, it correctly pointed into the right spot but then it forgot where the right position was.
I have done the upgraded ROM ( even tried Ivan AKU 3.2 ROM ) but problem still persisted.
I just tried clean up the edge of screen, finger cross, hope it fixes my problem.
Bad thing is, I bought my device from UK and I am living in Australia so therefore, my warranty is definately invalid. I don't want to spend 200 AUD for the new screen ( unless I am 100% sure that LCD is faulty ).
Anyone has any idea or even a better suggestion because I don't see many people having this problem.
I suspects that maybe the flex cable got ripped but not totally ripped. Don't know , please help me out on this one
Best regards
Anyone has any idea about my problem ??
One question :
I know that the flex cable has 2 connectors ( one is for LCD display and another is for LCD function ). Now does LCD function relate to the touch screen function ? and if one tiny wire of the function cable got cracked, but not totally cracked, will it affect the touch screen function ?
Other thing, does WM5 store any setting relating to screen alignment setting ? If yes, where is it ?
Thanks
Hi, from another forum, it only help to bypass the alignement loop:
"here you go theses are simple steps to bypass the touchscreen alignment.
Install you activesyn blah blah blah when it finds it go on my computer and go into your PDA device
go to windows startup and delete the Welcome file
after that give your PPC a soft reset and BAM u by passed the screen now get a free desktop program liek pocket controller from the internet it will automatically install on your pda and BAM you can control your pda add music and whatever
but now if you want to click stuff on the road get pen irazu just search on google and send it to your PDA then go to file explorer and double click it and you got a cute little mouse program that you can use like a stylus"
also try this little soft:

Hi godtakeit!
I've had the same problem a few weeks ago (and still having it from time to time) and for me a slight (very careful) bending of the screen makes it work again. It seems to me that there are connector behind or near the display which has some loose contacts.
Did you notice any other problems which came in conjuction with the alignment problem (e.g. speaker not working)?
.ox
Hi oxident
No, I don't have problem with speaker ( it was not working before but it is because of the jack plug problem - it solved ). Yeah, I did notice if I bend the screen carefully, the problem is gone. The funny thing is when I aligned the screen, it worked but if I closed it off and left it over night, it started again when I opened the lid.
You may right about the connector between LCD screen and mainboard. Well, I have no choice but openning the device and check it up.
Also, I read the thread somewhere in this forum and somebody advised this problem maybe relates to magnet around device. My brother aslo advised me that LCD charged and reserved negative electrons. Wierd but I am experiment it at the moment ( taking off battery and leave the device for a few days so that it can release the negative electrons ).
Hope it fixes
please help

You have one of the best HTC devices ever made!

Post number 2
Good luck,
Hi, going through the emails on this list was indeed very useful. I bought an iMate JASJAM in January 2007 and it started giving me a weird problem with the screen.
The phone was working perfectly OK till Mid Feb when I started noticing that any application I opened (including phone or contacts) got closed automatically within a second. I observed carefully and saw that the 'X' on the top left corner of the screen was probably getting clicked on its own. I suspected it is most probably a screen problem and took it to the iMate service center. They promptly replaced the screen in 2 days.
It worked fine for 15 days before I am seeing the problem again. Could someone help me please. I am seriously dependent on email through my phone for my work. Would appreciate any sort of guidance, even if it seems obvious.
My JASJAM is 647XX s/n based
Thanks a ton,
Aditya Deshoande
If indeed the X is getting phantom taps, this is not a screen problem as such. In other words, you could replace the screen time and again and it would recur. The issue is that the screen gets pressre/pressed by the bezel around the screen. The screen is rather stupidly sensitive to touches even below the bezel. Pressure can arise from a slight twist in bezel, from heat expansion and from dust trapped between bezel and screen. You might try the "business card solution" - though it is not guaranteed.
I would also take a backup and do a hard reset. Try the problem apps without restoring the backup. This will identify whether it's software or the SA related problem.
f the problem is still there, I would demand a replacement not a fix, because if something is out of line it's not going to be fixed by swapping screens.
Mike
Thank you
Mike,
Thank you for posting a reply so quickly. I suspected it is not just a screen alignment issue the moment it appeared again. None of the fixes mentioned for the SA issue work. I just wanted to check if anyone has any suggestions to try something. There are no applications installed by me and I have tried hard reset. In fact the crosshair in the align screen application keeps moving without me touching the screen.
The problem is that this problem makes the phone useless because I cannot open the dialer. We need to be extremely careful of what iMate and HTC seem to be shipping out. This is a damn expensive phone to have such problems.
I will request for a replacement but would not be surprised if I am refused and told that it will be repaired since it is warranty.
Let us see if I need to drag them to consumer forum. I will, if the need arises.
Regards
Adi
Good luck Adi - I hope it works out. Yes that jumping around of the cross hairs does prove there is pressure being put on somewhere. Indeed HTC did appear to have largely resolved the SA and SA related problems - but I'm still seeing quite a few.
Cheers
Mike
Heats up during charging
Hi Mike,
Perhaps the problem is compounded by the fact that it really heats up if you charge the phone while it is still in the cover. The one with a belt clip that comes in the box
My screen does not respond to any taps anymore. Which in a way is good because I am at least able to call as well as send/receive emails.
Regards
Adi
Same problem here!
So my Hermes, which just got replaced by Cingular after the "red light..not charging problem" (Thanks for the pointers on that Mike!). But my new unit is also having phantom clicks on the x or in landscape the Start menu kept getting clicks. And I too got the moving crosshairs during screen alignment setup. Now the whole screen is whacked, not repsonding to any clicks.
Cingular are sending out another unit. I love my hermes, but seriously getting worried about the reliability of these units. I really can;t be without my unti working for too long, I'm stcuk having to go back to my SE P900 (with a flaky battery) or my SE S700 which sux.
It is a worry and very frustrating. However, when you get a good one it is well worth it. A hassle I know, but some folks here say they've been through 3/4 before being happy. This is the secret I think, put up with no physical defect and get an immediate replacement. Use a cheap mobile while you wait for the replacement. Most of the 'pain' comes from trying this and that and the other to get the device working and perhaps 6 out of ten times you fail. Use the warranty without hesitation. There ARE good ones out there!
My thought for today!!

My phone last week wasn't receiving texts so I restarted it and when it came back on the touchscreen no longer worked. The little white light would go on when I touched it so it knew where my finger was but any movement would not unlock the phone so I couldn't actually do anything with it. Sure enough a factory reset fixed the problem but I am still waiting for them to get me a new one in case the problem happens again to me. Anyone else have this happen to them or just a freak occurrence for me?
My son has gotten a hold of my s4 twice now since I have owned it. Both times I couldn't get the phone unlocked even though the touch screen was recognizing my touch. Restarting fixed it both times for me. Not sure if this is the same problem you are talking about, just thought I would share.

Happened to me a few times. Both screen swipes and the capacitive button presses werent registering. Happened on lock screen, call logs (swiping to call wasnt working), and swipe to answer. Pressing the home button and going back to the app fixed it. Very random but annoying nonetheless especially when not able to answer a call
Seems like buggy software to me. I've had a different issue, my phone says I have data, but I don't, I've had to restart the phone to properly pick up a data signal. This has happened twice now. Seems to be like Samsung's touchwhiz is quite buggy...
Yeah restarting it did nothing for me, tried many times, took the battery out put it back in all that stuff. The same thing happened with my data, I had a connection that entire time that I was not receiving texts but none of them actually went through which is when the problem began.

What app were you able to get in to to fix it? Would like to know in case the problem happens again when they get me a new one.
This happened to me last night, about had a major freak out.
First I have a couple questions for all of you who had this issue, so maybe we can pinpoint the actual cause:
1. Did you get any type of moisture (even just a little condensation) anywhere on or around the phone? Mine started acting up after I accidentally put my phone on the coffee table where some condensation had formed from a drink being there previously.
2. Any of you drop your phone at all? Even just a minor drop...as the day before I had a little drop (maybe from a foot off the ground), but I do have a case.
The reason I ask is because I started having this issue immediately after the phone was put on the condensation. Don't know if that was the cause, though, because I'm not sure exactly which of the steps below actually fixed it.
First I had to identify the exact problem...which I found by turning on "show touches" in Developer Options within the settings menu. This brings up a little white dot on the screen any time it registers a touch. Sure enough, I was getting "ghost touches" on the top left corner of my screen every 30 seconds or so - and it would generally last for 10-30 seconds or until I turned my screen on and off (that would fix it temporarily). The ghost touch was causing my drop down menu to pull down slightly every once in awhile, as well as not registering any of my other touches (including capacitive buttons). I knew the screen itself wasn't broken, because any addition touches were registering via the white dot - they just weren't interacting with the UI.
After doing some research online, apparently there are a couple main reasons that this ghost touching could occur:.
1. Faulty digitizer. Obviously this would Suck, and I really hoped it wasn't the cause. To repair would mean replacing the entire screen, as apparently the digitizer is attached to the screen and would be very difficult to replace by itself.
2. Any kind of moisture, whether water, skin oil, etc, getting in the cracks of the phone and staying under the screen, causing the pressure to indicate a false touch. Possible repair options included putting the phone near a WARM (but not too hot) surface for a period of time to hopefully cause the moisture to evaporate. Also some people said it just evaporated on its own after a few days (again, I hoped I wouldn't have to resort to this as I'm impatient and don't want to be without my phone for that long lol).
3. Software issue. Possible fix includes toggling HW overlays and/or GPU rendering.
Here's what I did:
Took the phone apart completely, made sure there was no visible moisture anywhere (there wasn't). Intermittently blew the phone (from the back and front, while it was disassembled) with warm air from a blow dryer. Left it alone, disassembled, for about 30 minutes.
Put the phone back together, booted up, immediately went to developer Options and (a) disabled HW overlays and (b) DISABLED "Force GPU rendering" (I actually already had it enabled).
BOOM - problem was gone!
So like I said, I'm not sure which of those did the trick - or which problem I had to begin with - but I'd be interested to know if anyone else had similar issues and/or fixes?

I should not have had any condensation at all on my screen when it began. I was using the phone playing with WatchOn and setting it up for my TV, I was messing with it for quite a while and realized after a period I hadn't received texts in a long time (I normally get at least 1 every 10 minutes, I was going on a hour and a half with 0) which I thought was weird so I restarted the phone.
When the phone came back online I did not notice the white dot pressing itself anywhere, but anytime I touched the screen it would immediately know where my finger was and follow it around, but not actually press anything. When I held the power button and the little Shutdown and Restart options came up, if I sat there and just pressed either one of them constantly they would eventually recognize that I pressed something and do that action.
I was also able to get into the homescreen by getting the talk option to come up and backing out of it (The buttons on the bottom of the screen all worked fine) but once in the homescreen I couldn't actually press any buttons regularly so gave up on it.
The guy at the ATT store said he hadn't seen any other complaints about it so I did a factory reset while there (I had already backed up everything with Kies) and when it came back on there seemed to be no problems.
Like I said though I am waiting for a new one anyway, they are backordered at my local store (Should have got a new batch in Friday, not sure where my phone is now) so hopefully the new one I get doesn't have this problem nor the lag problem a lot of people have been getting.

Just the stock Phone app. My problem seemed like a software problem more than anything else.
But if you have to restart the phone in order for the digitizer to respond, thats a different story. A swap should fix your issue, since it seems so uncommon.
Ok, so first thing's first. I've been researching this for a few days now before creating this post. The touchscreen issues I'm finding online, are similar to what I'm experiencing, but the solutions have already been done, or my phone is not responding to them. I'm making this thread to see if anyone else has experienced the same issues or has any new news before I a) return my phone to stock, b) replace the digitizer, or c) buy a new one or upgrade to the G3.
My G2 was rooted, but kept on stock ROM with only small tweaks here and there. After the latest update, I noticed my work G2 had much better reception, so I returned my phone to stock to download the update. After updating, I re-rooted the phone, this time, the only thing I changed was the keyboard which I replaced with the G3 keyboard. Everything was fine for months until about a month ago.
It started with not being able to pull down the notification shade on the right half. No biggie, but after a week or so, it got worse. While using instagram, I noticed that the confirm button was sporadically responsive. Sometimes it worked fine, other times it didn't work at all. It began to progressively get worse on an almost daily basis. I decided to see what was going on and enabled both input options in the developer options menu. I found that the entire right side, about 1/8" was not responding to touch, the area not covered by glass screen protector( i removed it later while trying to troubleshoot). The upper right area showed about a half inch block that wasn't responding (the area where the data ribbon is). I was ok with that as instagram was really the only thing I used being affected.
About a week ago, the mid left screen area started being errratic. It began to get worse and started to affect the front touch screen buttons ( the area where the other data ribbon is). I enabled the input options again and saw that I now had a good portion of my left side of the screen was unresponsive. Even though I didn't drop it, I thought maybe the data ribbons had come loose as those 2 areas are where they are. I opened and disassembled the phone and re-sat the connctions after inspecting them. I double-checked all the other connections and LDIs in case humidity was the culprit. Everything looked good. Didn't fix the problem.
I've had to set my phone to unlock by facial recognition to ensure I don't get locked out, and changed my pin to use numbers not affected. I'm going to replace the digitizer, but wanted to see if anyone else had the same issue, or knew if it was, indeed, a software issue before I spend $75 (I will be replacing the digitizer and LCD to get it working sooner rather than risk damaging the LCD while replacing the digitizer and having to wait another week). I don't want to send it in to LG because I bought it on ebay and have no proof of purchase for warranty, and I want it working sooner.
One thing I noticed that may help with diagnosing, the screen now looks different when off. Before, in direct sunlight, you could see the dotted matrix from the digitizer, and that was it. Now, I can see the retangular pattern across the entire screen. I checked my work G2 which I just received a few months ago and the rectangular pattern is only visible on the edges of the screen, the center is black with only the dotted matrix visible. Keep in mind, this is in direct sunlight. In shade, the rectangles are visible on both.
I'm hoping it's a software issue, but I'm wondering if the digitizer is starting to separate from the LCD. I don't see any acutal separation though.
Thanks for reading the book, and for any feedback. Also, because it will probably come up, I want to avoid upgrading if I can because the G3 is just a little too big.
I restored the phone to stock with the most up to date software. Still doesn't work. It appears to be a hardware issue. I really thought it was software because the dead spots word for a split second after turning on the phone. Oh well. Guess I'm going to order a new digitizer or LCD combo.
Hi to everyone.
From 1 week my Mi9T has a ghost touchscreen.
How can i resolve it?
What do you mean by ghost touchscreen?

Screen responds to 'touches' you didn't actually make - like, there is a ghost touching your screen
oh, well i dont know how to fix that sorry. But maybe you touched the edge of the screen accidentally?
i have the same problem for about a week now! did you find any fixes?
me too
Me to. I have tried every possible solution. Eventually whole screen has been replaced on warranty.
No guys i dont find any solution. And now? How we can resolve it?

replacing the display is the only solution
i have the same problem, ghost touches in the upper side, near clock.. specially when phone is hot or i press the top of the phone
Im so angry ??? bc we have this phone not usable!!
It's a hardware failure. Faulty display. If you suffer from "ghost touches" you should back up the data you want to keep, and return your Device to where you have bought it from as it might still fall under warranty (depends op what the cause is, and where you live). This can also get worse over time making the screen partially unusable (which was in my case). contact the seller, or contact customer service from Xiaomi.
I suffered ghost touches at the beginning of December (owned the Device for at least a month). Tried every software options i found around internet that could resolve it, but it was to no avail. I proceeded to unlocking the bootloader, install TWRP, flash a custom rom... For a couple of days i was fine. After those few days the top part of the screen (the part with the status bar) rendered unusable, on custom rom and stock miui. Tested it and it seemed that the area increased and also decreased from now and then, which is strange. After contacting my seller they agreed on sending it back including screenshot and the tests i ran. 1 day after they received my device they contacted me to say that it cannot be fixed (or at least they didn't seem to bother as the phone's pricerange is low) and i am receiving a complete new one (this was in the weekend btw). After that weekend on monday i received the new one and it's running better then ever, even the fingerprint is much faster.
Now just as a warning, I don't say you still have warranty. i live in the Netherlands where unlocking, rooting and all that does not void warranty, and returning a product is very easy to do. But in other parts of the world the companies can screw you over so you'll have to check that.
For those who are asking what is it, juste have a look at mine in dev mode to show the touch : https://www.youtube.com/watch?v=-ZApYI9otJI
This happens to me only when I'm charging the phone, still annoying, , I think it's something to do with the voltage and could be fixed with a software update.
