[Q] Touch screen problem HW or SW? - Legend General

Hi,
just recently I bought a used Legend when I was abroad. It seemed to work alright at the shop but I soon discovered that it had a few flaws.
First the symptoms:
The Notification panel rolls down when I touch the screen often rendering the touch screen useless.
Typing on the keyboard in upright position brings down the panel, but if i tilt it it typing the letter "P" will give me "Q"
Some times the screen will start flickering when I hold my finger 10mm above the screen.
The HTC weather app does not show the correct local weather - 3rd party works.
Then to the problem solving attempts:
Reboot - solves the problem for a short while
Resetting to factory defaults - same as above
Disassembled to check for lose components or particles - none found and warranty void I know...
OTA update - I got the 2.1-updat1 2 days ago and the phone worked fine for3-4hrs before it started acting up again. HTC Weather was working.
OTA upgrade - got 2.2 yesterday and had another 3-4hrs without symptoms. HTC Weather app was working.
And a couple of questions:
1) Is it hardware or software?
2) If software - how can it be solved? I`m ok with rooting etc. but would prefer a less time consuming solution. I`m in a Linux environment.
3) If it is hardware - I would probably be able to replace the digitizer (if that`s the problem) but how do i locate it for sure?
4) Would this problem be logged in the phone if so how do i access it?
Software info:
Android version
2.2
Baseband version
47.51.35.17u_7.13.35.05
Kernel version
2.6.32.17-g30929af
htc-kernel(at)and18-2 #1

Build number
3.15.405.3 CL291292 release-keys
Software number
3.15.405.3
Browser version
webkit 3.1
I could send it in for repair but since the warranty is voided it would probably cost a small fortune and since I find it quite satisfactory to mend things I would really appreciate all the help I could get.
Cheers!

I do not Know how much time you spend with disassembling but it took me about one hour to root it and i was new to this
i think a lot of people can do it in less
i'm on linux too and it is not an problem ( look around for the linux method of creating the goldcard it is realy easy )
i had a similar problem when i tryed to use a screen protector
after removing this and aplying a new clean one it worked ok ( but not great )
after removing this new one it worked great
the legend screen is so scratch resistant that i prefer not to have anything on it
Good luck resolving the problem and please if you manage post how you did it
i'm curious !!

Well, took me about half an hour to disassemble and put the thing back together.
Thanks for the tip about screen protectors - have`nt used any but I thoroughly inspected and cleaned the screen just in case. So that one is ruled out
Any other with ideas of whats most likely, a hardware or a software/firmware error?
I will post if I get it resolved.
BTW: I`m in Oslo, Norway anyone that can recomend a good repair shop?

Hi gesax,
I just started having this very same problem a couple of days ago.
I was about to take my phone appart, but thanks to your post I at least know that it wont change anything (thank you for that)
Quite worried, cause I'm pretty much the only person in Argentina with an HTC Legend, so no chance of sending it to a repair shop
By any chance you found a solution to your problem? or did you have it fixed?
Thanks!
Noah

Have the exact same problem. Haven't found any solution. I'm gonna turn it in.
I have a theory, that usage in cold weather (well below zero) might have caused this...
Anyone who can confirm or dismiss my theory?
Sent from my HTC Legend.

I had the same
New screen for me after bring it to assistance

Yes, it happen to me. It's definitively an hardware problem.

Had this before. Well can't say exactly what the problem is. Might be HW or SW or maybe both. It happened twice to me. Once by software, more like rom actually. After a few days with CM, it stated acting weird. Reflash and everything is good. The other time is because water vapour got between my screen protector and screen. Thus resulting in such effects you're experiencing.

Screen fading to white ongoing issue- MONEY AHEAD!

Hi all,
I need help,suggestions,anything with an issue I've had for a while. Since the time I started loading WM6 the screen has been randomly fading to white. I have LSVW latest rom 22/4 SE and 1.40.10 radio and 1.40oli although it doesn't matter what rom you load. I tried going back to WM5 and its better but now still fades to white as well.
on advise from oli and legolas I purchased a new battery but still have the same issue.
I have dropped my phone once which resulted in a crack to the right of the DEL/CR keys so could it be a HW issue and if you think so is it one I could open up the phone and fix?
Any and all help appreciated
IN FACT IF SOMEONE CAN RESOLVE THE ISSUE I WILL DONATE SOME CASH TO THEM!
test
Im updating to
LVSW 4-23 Full, Radio 1.40.30.00, SPL 2.10.Oli, IPL 1.04
seeing if any difference comes out.
This is not the first time this issue has been reported:
http://forum.xda-developers.com/archive/index.php/t-301003.html
The conclusion is that it's hardware related. It may be as simple as one of the internal ribbon connectors having a less than firm connection. It may be brought on my anything from physical movement or pressure to internal pressure if the device gats warm. However, it is possible that there is a failing component. IMHO, a case of take it for replacement/repair or first check connectors if your brave and not worried about a warranty.

HHmmm interesting thread .. the only issue i have out of that is the fade to white one.
Maybe Hardware .. i got the phone off ebay and now it has a crack in it .. so i dare say it isnt under warranty any more. (even though its a max of 6 months old).
It may also be software. I experienced the WSOD on my JASJAM when playing with the GPS-related DLL's. Once this problem appeared when switching on the camera. The screen would turn white and soft reset would not fix this, only power off/on would sort it out. Seems that the drivers do not reset (some of) the hardware to a known state on boot.
Had EXACTLY the same problem. Hoped it would be a software problem. Hard-reset a few times to no avail. Upgraded to a couple of the WM6 ROMs. No change. I did notice that when it was cool it tended not to happen, but after being on the phone a couple minutes or using the PDA for a while, it would do it AGAIN.
One weird thing I noticed was that if I did a Soft-reset and held down the Left Soft-key, I could "force" it to fade to white on start-up! VERY WEIRD.
I finally bit the bullet, and sent it back to Telstra to get it sorted. Didn't want to void warranty myself.
It has been just over 2 weeks since I sent it off, and They have sent this reply...

Hello, I am emailing about an I-Mate JASJAM phone I sent for repairs early last week (tel # xxx ).
Can you please update me as to status of this repair, as the Telstra shop did not provide me with a second phone while I await return/repair/replacement of the phone.
Thanks,

So, I guess it IS a hardware problem. But then again, that kind of reply, sounds a bit "dodgy" as it doesn't seem to "technical" does it?
Hope this helps.

Their reply was not very technical - does not surprise me however. The people who repair these devices are usually faced with some component/connection/screen or a m/board that needs replaced. They often fail to take account of something as basic as the case pressing on the screen or other components - particularly when device is warm. So they replace the component they think is faulty and then discover the problem is still there. With this issue in particular I think that there are no faulty components just the case is a fraction of a millimetre too tight for the internal components and hence swapping out parts can have no effect. With this fault I advise people to go for a replacement not a repair if possible.
NB: This issue should not be confused with white screen that may appear after installing particular software or when an application crashes, or when the flashing of a new ROM goes wrong! The hardware issue arises most commonly when the device gets warm or put another way goes white after maybe 10 minutes of use and will continue to go white even after hard reset.
Mike
I have this same problem! =(
My phone screen recently (4-5 days ago) started to go white. I never saw this happen with my own eyes but when i picked up my phone and its sleeping i push the power button to get to an all white screen. I can hear noises when i touch the screen but no image other than white. I can solve this by removing the battery and putting it back in, then my scren works fine....its not verry often just like 1-3 times a day.
I want to try a hard reset but have a question first: My phone is unlocked by the ebay guy i got it from, will a hard reset lock my phone back to Cingular?
Next i want to try upgrading my ROM and Radio and anything else...im looking in the wiki for instructions on how to do this. Any help? What else shouls i upgrade?
Ive only had my Hermes for around 2 months so im new to much of this.
THanks!
I recently purchased a Used Imate Jasjam (Ex Telstra Australia) with this issue.
I pulled the unit apart, and reseated and pressed the Power and LCD Display Data Cables... attempting to ensure they were firmly fastened.
I then upgraded to LVSW's Latest WM6 Release.
I have had the Phone go to White once in that timeframe since. I brought it back by pressing the power button of, then one again.
I don't feel that it's really a "100%" Faulty Part... Because it works fine othertimes. It almost seems as if connections or a Data Cable has an Issue.
I'm intending tonight and using the Phone over the weekend to see if the issue continues to occur.
BAD NEWS!!
Well, got my phone back after a bit over 3 weeks I think? I kept ringing the repair center and emailing. Finally they said it was ready, and was sent back to the shop I bought it from. Rang the shop "no it's not here yet, we will ring you"... now the repair centre to the shop is a 20 min drive... on the 3rd, I rang again at 1pm and "no it's not here yet, we will ring you when it arrives." At this point I was really getting p*ed off. So I went to the shop, and demanded, and guess what was AT the Shop?!?!?!
Anyway, after 1 friggin day, I have lost the Red & Green phone buttons! As of tonight the whole bottom section no longer work, and the screen has gone white again.
The repair report listed 3 things replaced...one was a "bezel" another was a "poly" something. I will get the report a list the replaced bits if anyone likes, but their descriptions are kind of strange if ya ask me.
Anyway, I have to send the phone back for repairs again, which could take another 3 weeks +, which I think is completely PATHETIC OF TELSTRA, especially for the fact they dont give the same phone or even similar to "loan" while I wait for my defective $1300 phone to get "repaired"... (more like 'fiddled with' & "yeah, she'll be right mate"...
GRRRRR!!!!
My girlfriends phone was having the same problem. Try popping out your SD card and putting the phone into/out of sleep and see if that brings back a visible screen. Thats how we determined her situation was a hardware problem and not a problem with the rom.

Yes, sadly this is kind of predictable as I said in an earlier post in this thread:
http://forum.xda-developers.com/showpost.php?p=1233420&postcount=7
This is why, as I said, get a replacement not a repair if possible. My view is that the individual components are fine but connectors come loose or the heat generated causes pressure to be put on the screen etc So it's a problem with some cases and how the innards in some cases get squeezed. So off course changing the top poly board, connectors, bezel gasket, may by pot luck make a difference but is just as likely to make no difference at all.

Status Report:
After having my phone playing Video's Through the Night (My Way of a "Stress Test" to Generate Heat) I woke up the find the screen to be "almost completely" White.
Usually its gone completely, however in this instance I was able to see the icons through the whitewash.
I put the phone into sleep and back out and the Display is fine again.
Being that these phones are much easier to pull apart and put back together than my old JasJar I might to do some further experimentation.
I think the issue will have something to do with either one of the following
- Heat
- Pressure on the LCD from Parts Around it
- Faulty Ribbon or Power Leads to the LCD
My suggestions
- In the Case of Heat... I'll run the Same Test, with the Phone Directly in front of a small airconditioning unit I have.
- In the Case of Pressure, I'm going to look and see if I can place some extra Insulation Tape or Similar on the Phone to relieve this
- I wish I could find somewhere to buy the Replacement Ribbon Cables but I don't know where I can get them in Australia... any ideas?

We wait to see. Mind you one guy on these boards found he could get half an hour from his device if he put it in the freezer for a while - so I'm not sure that air-con will be strong enough!!!
Mike
Well Results.....
After pulling apart the unit and reconnected, I think I found my cause to simply be excess pressure.
I've removed the "Black Plastic" Micro SD Card from its Blanking Plate.
Since I've done this... not one White Screen Whatsoever.
I don't use an SD Card, so the issue is resolved for me, however it is very interesting.
Could be Pressure or Heat (Small Hole Might Increase Airflow/Allow for Greater Dissapation or something)
Hi folks,
i've also small experience with this "white screen" issue and just wanted to inform you about it.
I got the device from my former boss who did already complain about this "white screen" issue on his O² XDA trion with original ROM. (honestly i did not really believe him due to my experience with couple of other devices so after i got the device i was just wondering - ok back to the facts).
I installed on Friday the Windows Mobile VI Pro - BLACK 2.5 Release and until today it was running (as far as i remember expect one time) nearly perfect w/o white screens. About 45min ago, i flashed the device with BLACK 3.0 Release and got until now about 5-10 times a white screen.
I assume this is not a hardware ONLY issue but indeed very strange.
I'll go back to 2.5 and will look forward if i get again the white screen or it'll be ok.
Cheers so far

You are right to ask the question "is it hardware or software".
1
We know a white screens can arise if folk duff up flashing a new ROM.
2
We know there is a hardware caused white screen that comes and goes often when device gets warm.
3
But there maybe white screens caused by some kinds of crashing software or a buggy ROM etc
Crucially in terms of finding a cure will be distiguishing between these.
2 for most people is easy - take it back and get a replacement.
1 is a matter for the ROM upgrading and fixing boards
3 is a case of trying different ROMs testing 3 party software by selective installation until the problem starts or stops.
In your case I am worried that this is a number 2 device as it did sometimes get the problem before you flashed the ROM and now it's worse. It may only be worse because this particular ROM is generating more heat and consequently more white screens. (see explanations elsewhere).
I suppose if it's an occasional problem you might live with it but otherwise it's replacement at best and repair as a rather dodgy alternative.
Mike
Hey Mike,
well, before flashing the device with a custom ROM, in my opinion it was really difficult to use it.
By flashing it with V 2.5, it was very good usable and with V 3.0 it returned to become more unusable. Nevertheless, i upgraded 10min ago with HARD-SPL-V7 and it's running fine now (i've been wating with downgrading to V 2.5. If it returns to become unstable, i will downgrade to V 2.5 again.
I'll keep you informed.
yes for this particular "white screen" issue it will be useful to hear how things go - thanks
Mike
White screen - in my case definitely a hardware issue
Hi folks,
i was testing and playing around with my Hermes and today i found the problem (very funny because now i can't reproduce it anymore but just read ahead).
Today i was playing around and after pressing by accident on the case of the Hermes, the screen appeared disappeared and changed into white.
Please download the video i recorded from the attached link - you'll see that it was able to reproduce it by tapping on the case:
http://asuka.descipe.de/dphome/test/HTC_Hermes_White_Screen_issue.mp4
Please use VLC or MPC (additional codecs required) to watch the movie.
Honestly i'm not sure if this can be reproduced by anyone but this makes the whole situation much more clear.
Any feedback is welcome.
Cheers

Vibrate has lost its buzz

G'day all,
My HTC P3600 has been nothing but problematic since I purchased it August 2007. The screen has been replaced twice and I thought everything was on track.
NOW I have noticed that the vibrate function no longer works at all. Not for phone calls, sms alarms, nada!
The people who have been repairing the last couple of times have had the phone for 3 weeks and now tell me it's something to do with software/firmware specific to the vibrator hardware.
Has anyone heard of such a thing, or could possibly explain to me?
I am running bepe 0.79 OS: 5.2.1908 (Build 18508.0.7.0) but it also doesn't work with the factory release OS from HTC
Regards,
WangChung
sounds like it broke from the inside. i don't see how a vibrate function not working could be a software problem. especially with two roms.
what kind of screen problems have you had btw?
Thanks for your response viperx,
I agree with you that it sounds unlikely to be software related for the the vibrate not to work. Personally I think the mob repairing this device for the 3rd time have absolutely no idea what they are doing and are just trying to bull$h!t me and stall for time
As for my screen issues previous to this. The "Start Menu" activation of death I guess you could say. The ubiquitous On of Off of the Start Menu finally resulting in no screen response at all.
The entire screen was replaced the first time, then they told me on the second occasion that it was only one component or layer of the screen that required replacing on the second failure. Personally I've never been comfortable withthe people repairing the device, but when you buy it overseas and have no local warranty, little you can do I guess.
WC
I've had the start menu problem, not bad though. i'm hoping it won't give in. might be becoming more frequent though.
good luck with the repair shop then

I agree with viperx, I flashed my device with many different rom, official and cooked, and never had problems with hardware components I think that the people who have been repairing your device last time, forgot to plug some connector ( of they'r brain ) hope they hadn't broke anything...
Good luck

Digitizer replacement?

The warranty for my HD is gone and I would probably need to change the touch screen digitizer myself, found these on ebay for ~60€, but does anyone know how to change them? Again, any help would be appreciated!
Originally:
HTC Touch HD, it has been a wonderful phone until now. I have encountered a wierd problem with the touchscreen.
First the touchscreen stopped working completely, after awhile it suddenly started working, at first it recognized some bits and pieces but now it recognizes every touch as normal, except..
It is very inaccurate and the "sum of inaccurity" seems to change depending on where I push the screen, the screen alignment option in settings does not fix this.
I recorded two videos to show this problem better:
http://www.youtube.com/watch?v=Xd1vjiHr2QU
http://www.youtube.com/watch?v=TynTTFIQJv8
Any help would be appreciated on how to fix this!

I have handled it with great care so no big knocks or drops. Ill contact the store about the warranty. Just wondered if theres a way how to simply fix this.
Just noticed, the screen works normally sometimes for one touch, then it goes back to the inaccurate **** :/
Im now guessing that some cable could be loose or something like that?
Have u tried recalibrating the screen? I can't remember exactly where I found it, but its in programs or settings somewhere.

I can tell you from previous experience, HTC does NOT warranty touch screens. You mentioned "a store", so I hope they help you, because HTC will not. >sigh<
Seems a little unfair if they don't seeing as the HD is purely touch screen!

Hmmh, well the store probably sends it to some service center here in Finland that fixes HTC phones.
Indeed sounds very stupid if the warranty doesnt cover the touchscreen.
Perhaps my HD suffered from something else than a broken touchscreen, eg. mainboard or a chip that controls the touch screen. Who knows I'm just hoping it "passes" the warranty :|
Well... Had Hard-SPL on my touch hd and duttys 1.7 rom, so the warranty is gone
Didn't know they were so picky about it, they said it would cost 605€ to repair the screen. So now I should probably start looking for a screen digitizer on ebay and some help on how to change it... Already downloaded the service manual, but there was nothing on how to change the digitizer, could anyone here show me some light to this? Thanks.
I have dismantle my HD to see if there's any way to change only the screen (it's broken)
There's no way, as far as I saw. You have to replace LCD, tourch screen and screen. It's one piece and there's no way easy way to open it without break it.
You can find all of them for about 200E.

Another sad story // hopefully with a good ending
I kinda have the same problem as Viba and others. Sorry for the looong post. But decided to describe in more details my experience up to now, and hope you can help as well.
All of a sudden, I started having problems with the touch screen of the Touch HD. I started noticing that whenever I touched the Touchflo buttons, the phone vibrated. Soon I came to realize the if I touched in some spot, the phone recognized that I was touching lower, to the point that it could not recognize touches in the taskbar, for instance.
The united has 2 or 3 months max. It had some falls before and I do not really know who (or which one) was the culprit.
Tried this as fix: re-alignment, hardresets, Official ROM upgrade. Then I started reading and understanding that the problem was probably the digitizer ("nice to meet you").
I live in Brazil and the Touch HD is not expected be released here any time soon. So the few HTC service centers do not know how to fix it and do not have parts for it. And also, I bought mine from an auction site by some user who bought it abroad, with no warranty whatsoever. I am left alone in this.
I was very frustrated and eager to get my device running again. So I started looking for a new digitizer and also the tools to open my phone. The digitizer (just the digitizer, not the LCD screen) I ordered from an ebay shop in Hong Kong on Monday and is expected to still arrive sometime in this century (IF Brazilian port authorities do not mess up). The tools arrived yesterday.
I downloaded the service manual and said to myself, let's see if the digitizer problem is maybe due to a loose flat cable. Got to work and carefully disassembled the device as per the service manual. (I have to say that, although I try to be carefull, I always scratch, bend or mess something up when I do jobs like these. So I was afraid of cracking some plastic or worse and actually did some.)
Up to where the service manual show, it went incredibly very well. But that's the problem. The service manual guides you to disassemble the unit up to the point where you are with the bezel, LCD and digitizer in one piece.
But hey! I saw zillions of internet shops selling the bezel (actually, the hole housing, but with no LCD), the digitizer or other parts separately! What is going on?
So I started trying to unmount the bezel, LCD and digitizer. Tried several things. It got really late. I was impactient. So I tried splitting the digitizer from the LCD, by inserting a hard plastic aluminium tip between the digitizer and the housing. A very thin plastic kind of tape came out (at lest part of it). So I tried doing it more. No success. And then I put a very thin screwdriver between then (just enough to get an ulgy bent it the plastic housing).
When I had played enough with that puzzle, I gave up and began mounting everything back. The good part is that I was able to get everything back and the phone is working. Well, except for the digitizer.
First thing I did was to kidnap the wife's Nokia E71 I bought her last month and she is not using yet (she couldn't learn to use yet; well, she hasn't even tried it), because I have to have mobile access to my emails.
And I really started now to consider other alternatives. Will some user like me EVER be able to change just the digitizer? Is it even possible? If it is, I would like to give it at least another shot.
But I am also afraid that it could be another part which is in failure. I just don't want to spend more $$$$ in this. It would be better to buy another phone (and maybe not a complete touchscreen - gosh, I miss my Tytn II). I so regret being a gadget freak and not waiting a release in my country.
Shoud I send my phone abroad for a service center repair? My sister lives in Dubai and she may be able to help.
Should I give up my unit and seel the used parts in ebay?
Hope to hear your suggestions. Thanks anyway.

Well... Had Hard-SPL on my touch hd and duttys 1.7 rom, so the warranty is gone
Didn't know they were so picky about it, they said it would cost 605€ to repair the screen. So now I should probably start looking for a screen digitizer on ebay and some help on how to change it... Already downloaded the service manual, but there was nothing on how to change the digitizer, could anyone here show me some light to this? Thanks.

before doing this what about removing hspl and reflashing back a stock rom
change shop and you might, and i say MIGHT, be lucky
much better than screwing up the machine

Nice to know I'm not alone with this problem
Sucks that the digitizer couldn't be removed separately, would help alot if someone knew how to do this, if even possible..

I have already tried with 3 custom roms and 2 original SPL:s with two original roms.
The Finnish law allows me to get my HD replaced if I could prove that the custom rom didn't brake the digitizer. Already sent some emails to the local repairstation for HTC phones here in Finland, lets see...
I run a repair center (US). I have not gotten curious enough to take mine apart, but if someone has a dead one to experiment with, PM me.
Broken digitizer glass
I have the same problem with the digitizer glass being broken. I have had the back off the phone and stripped it back as far as I dare, but the service manual just doesn't tell you how to replace the digitizer and glass only. Checked out youtube where there are many videos with instructions on how to replace the screens and digitizers on lots of different phones as well as the iphone, just nothing on the Blackstone yet.
Any one else found a solution or decent instructions?
Today I disassembled my HD too, found a loose screen wire but nothing else. Even when I attached it properly the screen didn't work.
Has anyone found out how to change the digitizer?
some info
Hello,
I am also have HTC Touch HD, and I am also thinking about replacement of touch screen and housing because of scratches. Here instruction in Russian
http://www.pdacenter.ru/razborka/htc-touch-hd/
step 24 is not shown on the picture, but there is mentioned that in order to replace screen you should push it forward from back side of the screen; also mentioned that screen is fixed with double sided tape (probably it is fixed to the touch screen)
Also, did you try to use any polish to remove minor scratches on the touch screen? HTC Touch HS has resistive screen and probably may be polished (in contrast to capacitive touch screen that has some coating).
All the best
Also, about this problem see

You guys should be smarter! If you want to warranty exchange it, flash the normal SPL again and flash a stock rom!

[Q] Legend notification panel and screen issue

Folks ~ On Aug 10, 2010 I purchased an unlocked HTC Legend (A6365 – HSPA 850/1900/2100 Mhz). The phone operated wonderfully until Sep 8, 2010. At that time, the Notification bar couldn’t be “pulled-down” anymore. Additionally, without rhyme or reason, when I touch the screen, the notification panel will open randomly. This renders the phone useless since every time I touch the screen, the notification panels opens. I tried a softboot and a factory reset. Neither action resolved the issue.
I contacted HTC USA support and they suggested clearing the calendar data and vigorously rubbing my hands together and then touch the screen whenever the issue occurred. No success. This issue occurs whether the SIM card is installed or not. I can safely say that no new applications were installed within 48 hours of the issue starting.
I search the available forums and found at least three other instances of this same issue. Regrettably, none of these threads have any answers to the issue.
HTC support then recommended for me to contact HTC Return Merchandise Authorization & Repair Center. This group (in the USA) cannot accept the phone for troubleshooting because this phone is not available in the USA.
Based on the behavior thus far, I suspect this is an issue with the firmware becoming unstable. The phone hasn’t been exposed to any drastic environmental changes (heat, cold, excessive dust, etc). Software info follows:
Firmware version: 2.1-update 1
Baseband version: 47.37.35.09U_7.09.35.05
Kernel version: 2.6.29-9e497c43
Build number: 2.02.666.3 CL1777708 release-keys
Software number: 2.02.666.3
Browser version: WebKit 3.1
By know, HTC should have received multiple complains of this issue and I hope they have a solution for it. The options of the phone are great, reception is wonderful and performance is superb (except for this issue).
Your assistance is greatly appreciated!
i had a similar behavior for just a wile and it was related to a screen protector i had on my legend.
after removing this and cleaning the screen very well it was gone
i suspect there was a conductible particle between the casing and the screen that mixed up the induction system of the touch screen.
sins then i have a little prog on my legend that shows the touch points he recognized : http://www.appbrain.com/app/com.batterypoweredgames.mtvistest
maby this is not related to your problem but you never know
Good luck
I have the exact same problem that occured after mounting screen protection.
I got the suggestion from support to do a factory reset.
I'll try that tonight.
I also saw this tip:
forum.xda-developers.com/showpost.php?p=4894244&postcount=36
(I got this message when trying to post the link: "To prevent spam to the forums, new users are not permitted to post outside links in their messages. All new user accounts will be verified by moderators before this restriction is removed."
I look like an internal link to me)
Sounds possible since you have to puch the air out when mounting screen protection.
So perhaps to much pressure to the screen causes this problem.
Nope that didn't work...none of the proposals.
Next step, send it in for service.
I had this exact same problem! It also started happening after I applied a Zagg screen protector. I thought maybe it was because water got inside the phone.
I removed the protector since there was a hair underneath it but the problem persisted. I was having the exact same symptoms as you (notification area acting wonky).
I got the phone from future shop and they have a return policy... for $10 a month you can return the device at any time during your contract and get a brand new one no questions asked. This is what I did and my new one works perfectly.
As a side note..I originally had a palm pre which started acting strange so I brought it back for replacement and since future shop no longer supports the pre I was given a choice of a different phone. I chose the legend and absolutely love it. I loved the pre but the legend is a much better phone.
sorry for bringing an old thread up... but i have the same problem...
is there a solution to this? ... except RMA, because the warranty has just ended...
the notification wont swipe down and opens randomly... the screen has been tested and is workin ok...
thx...
Have you tried wiping your screen? I get this occasionally. But just wipe helps remote dirt that messes up the heat sensors away.
Sent from my HTC Legend using XDA App
You can try pressing harder digitizer just abowe home and menu button but that may work just temporarely. Replacing digitizer you will fix this problem once and for all... Sorry

Ghost touchscreen

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.
