Screen Issues - 8525, TyTN, MDA Vario II, JasJam ROM Development

Hello All,
Since installing WM6 I have been having some strange screen issues. I suspect it is just coincidence. I have installed various different roms and I am having the same trouble ( currently latest lvsw ), making me think it's probably actually a hardware issue.
The screen behaves as if the top right corner is being pressed. This closes apps in portrait and brings up the start menu in landscape. It doesn't happen all the time, but doesn't stop once it's started.
Has anyone heard of this? Is this the same problem as the alignment issue? I have tried the buisness card fix to no avail. Should I take the phone apart as described in one of the fixes for alignement or do I need to send the phone off?
Yours hopefully...

How old is your phone? Some models had screen alignment issues which could explain your problem. Have a look at this thread and see if your serial no (HTxxx) fits with those with known problems. If it does, read Mrvanx's guide to put your phone ROM/SPL etc back to original status then send it in for warranty.

Mine is a HT648 which doesn't have any known problems with screen alignment. I have moved to canada, so although I am still in contract with vodafone, it is very difficult to send it back for repair. It will be my fifth replacement if I do!!! All previous ones had the screen alignment issue, this one is at least slightly different.
I am tempted to try the dismantling fix described in one of the other threads, but perhaps I should ship it back to the uk for a friend to hand in to vodafone for repair and then have it shipped back over here...

If you open it you void your warranty. If it is the screen alignment issue and you fix it, then you are good. If you open it and it is not the screen alignment issue then you just voided your warranty and cannot get it readily fixed. I had an earlier TYTN and I had the screen alignment problem pretty bad. I opened it and fixed it. It was pretty easy.
I would probably try to install a different ROM and and see if it still happens.
Good luck.

I've tried lots of Roms, unfortunately that hasn't fixed it. Reflashing back to voda and sending back seems sensible, but I'm not sure I have that much pacience!

i did the business card technique. use a business card around the edges and take out some of the black brittle gasket. make sure you keep it real clean around the edges.
I used a microfiber cloth to get under there with some lens cleaner. I read on another screen alighnment post to put a small piece of business card under the lip of the lower portion of the screen(that probably doesn't make sense but do a search for screen alignment).
when you slide out the keyboard i loosened those screws a quarter turn. someone also made a mortscript for screenalignment that helped as well,

Hi !
I have the same problems with the same ht648. The problem occured step by step. First after upgrading to WM6 everything works fine. But since 25th my device starts problems with the touchsceen so I can tap on it everywhere without response. I think it is a thermical problem, because when I put it into the FRIDGE the touchscreen works again for a while.

Have same problem here i also have a v1605 HT648 and i have had it for a month now. It has worked well till yesterday when it started exhibiting this problem. I haven't done any ROM upgrade or anything.
This is really a pain - i hope i can get it replaced

Same problem....
I'm experiencing the same problem on my herm100. It has been like this for a few weeks now. I'm running the latest T-mobile test rom. I have problems with the buttons and also the screen both going white sometimes and shifted down a little. So I also see some little part of the softkeys at the top of the screen.
Anyone know what is causing this, and how to get it solved???

Struggling to properly display 6.5 UI

I recently updated my TP2 to WM6.5 (from 6.1) and am finding that the unit is not comfortable with displaying the new UI. All menus now appear surrounded by messy line structures which occasionally even leave traces after the menu has gone. I also find that the spacing of items in the new menus is overly-large. Whereas before a menu of five or six items could appear on screen, now only four are visible (landscape mode, 8 in portrait) and it is now necessary to scroll through menus where it wasn't before. Is there anything I can do about this?
Many thanks.

Can you post a screenshot of the graphical corruption you describe?
I might suggest reflashing the upgrade before you get much further, some users have reported that doing so has resolved all kinds of odd behavior after the Tmo 6.5 upgrade.\
However, the resized menus you're talking about just sound like the normal change in 6.5. I think there's cabs around here to revert to the old menu styles, but I'm not sure. The idea of course is they're more finger-friendly this way, but you're dealing with the obvious side-effect of that.
Many thanks. Here's a screenshot as requested.
Hmmm ... cabs which allow me to keep 6.5 yet return to the 6.1 menus? YES PLEASE! If anyone could possibly point me in the right direction...?
Cheers.

Ouch, that's pretty ugly! Yes I would start with at least a hard reset, but really I'd suggest just reflashing the upgrade, and see if that makes any difference.
Now I think I've seen cabs for that (the older, or at least smaller, style of WM menus), if not a reg entry...but I honestly can't recall or find where at the moment
EDIT: one more quick question- what carrier are you with?
Thanks for the advice. I guess that will be my best course of action, unless I can track down a menu-changing cab or reg tweak, which would then very possibly negate needing to do a hard reset or flash. I'll give it a while and see if anybody else can perhaps help with such a cab first.
Cheers.

REALLY!?? WHERE???
Please, I'd give my first born if I had one, I HATE the 6.5 menus, the old ones were friendly enough.
I had the same issue as the OP when i updated to 6.5 ...
Graphical anomolies that looked just like his, and it wasn't just menus getting frozen, it was programs and switching tabs and going from one text to another, switching e-mails...
Perhaps the issue with 6.5 is the graphics driver??
- Mark
Guys just do a hard reset and let everything run its corse. 9 times out of 10 this is the biggest issue with flashing a new rom. It's always best that after you flash your phone you do at least one or two hard resets to set all the files and reg entries where they are supposed to be... why? I have no idea but I know when I flash I always do a hard reset and never seem to have the issues others do.
I tried, Aaron, I tried! I bit the bullet and did a hard reset, then re-flashed the 6.5 update and then did another hard reset. And when it was all done the menus were perfect and everything was the way it's meant to be ... ... ... for about 10 minutes! But then from one moment to the next it was back to how it was before. Grrrrr!

Does your phone feel noticibly warmer after running for that amount of time?
Yes! Absolutely. After half an hour or so of using TomTom - constant screen on - it feels only a little short of worryingly hot.

I see...well the reason I ask is because in regular PC's, graphical corruption like that is usually caused by either driver problems, or heat issues...when the processing chips get too warm, they can start to display all sorts of weird things.
I don't know how to eliminate drivers as the cause in this case, other than the fact the issue seems fairly isolated, if there were driver problems we'd probably see a lot more people with this issue.
As for the heat issue, I can offer this experiment for now:
Get a ziplock bag (or something else that won't leak), and put some ice cubes in it...when you've got the phone working where you don't see the issue at first, when you first turn it on, lay it on the bag of ice and let it sit there for a bit while you operate it as you normally would...see if the graphics still go wonky after a while, or if that eliminates it or at least delays it.
EDIT: Yes, it would be a good idea to wrap the bag or whatever with a cloth (shirt, whatever) as well, to keep possible condensation away from the phone. Obviously the point is to keep the phone extra cool for this test, so just use common sense when working out how you prefer to do that.
Make sure you wrap that ice bag in some sort of cloth to absorb the condensation, or you will have a waterlogged rhodium. Even if you were to save a water damaged phone and get it working again, the phone's life would be greatly diminished due to oxidation of components.

Well that's normal. The reason your phone is warm after using tomtom with the screen on for 30 minutes is because the gps is active AND the screen is on so the phone is going under some pretty heavy usage.

Even after reflashing the phone like he said he did that its a little more then that and it's likely hardware..... ie.. warranty issue with HTC. Go to your carrier and show them the phone. They'll do one of two things, the first give you a new phone on the spot.. the second fill out a form and have it so you are shipped a new phone, when the new phone comes you use the prepaid packaging HTC sends with their warranty phones and put your own one in. If you have flashed a custom rom you have to remember to put back your stock rom and get rid of the HardSPL
I must agree with Aaron. I don't consider overheating when using TomTom to be an issue.
I'm afraid you misunderstood my situation Sirphunkee. The display problem is permanent, allways there. It was only "not there" for about 10 minutes after I did the re-flash and hard re-set, since when it's been permanent again. I don't believe I have an over-heating issue, and I can't see how the menu problem could be heat-related, since it's there 100% of the time, even when the unit is stone cold.
If only someone ... anyone! ... could come up with the link to the cab or reg-tweak that returns WM 6.5 to the 6.1 menus, not only would that very possibly solve my problem but would also return me to the much, much better menus.
I think I've discovered what my problem is. I can't give details, but I think it's the "Winterface" UI that I am using. Just now I had cause to replace all the Winterface files, and blow me, suddenly my menus are fine again! That was two minutes ago, so it remains to be seen how long this will last!
UPDATE:
OK, here's the latest: unfortunately within minutes the menus were bad again. I've now updated to the latest version of Winterface, however that hasn't solved the issue. Although the obvious answer would be to change my UI, I am extremely loath to do that as I'm very used to and very keen on Winterface, so I'd like to first try to tackle repairing the issue. Now that we know that Winterface is behind the problem, can anyone offer any suggestions how to address and repair?
Incidentally, I can confirm that it is Winterface that's causing the menu problem. In between uninstalling and reinstalling the two versions of Winterface I played extensively with the device and all the menus were normal.
Have you tried downgrading the rom to 6.1 again to see if the problem persists? And have you searched here ------> Windows Mobile Development and Hacking Specifically the "Windows Mobile Development and Hacking General" Forum?
You're odds of finding the answer will probably drastically increase by doing a search for your answer there. I swear I saw a thread once in there about getting 6.5 menu's on 6.1 Although I dont recall if it worked the other way around.

[Q] Mytouch 3g Slide Screen Issues ? (WARNING : EXTREMELY LARGE PHOTOS)

So recently my mytouch has been getting worse and worse. I'm not exactly sure if it's me or if it's the stupid phone because it's been degrading over time for some strange reason. First of all, the camera is **** for some reason, this is my second replacement phone from T-Mobile and it's extremely blurry for some reason(apparently it's a common problem but not common enough apparently for the tmobile representatives I've met with have seen before). Secondly, it's been becoming unresponsive at times although i kill my apps after i'm done with them(I probably only have internet, and facebook running most of the time). Third, ever since I've factory reset it, it's become very glitchy for some reason. One of the problems is that I would close the physical keyboard but after sending a text and all of a sudden the screen goes black and the only thing to fix it is to hit the power button and press it again to get it off of sleep. Another problem is after i send a text i close the keyboard and the screen repeats but the location of buttons is still where they're suppose to be on the screen.
Pics of what I'm talking about :
First problem(Camera)

Third Problem(Glitchy screen)

Fourth(Repeat Screen)

Dude.. you dont need pictures, and if you post them.. resize them first.
Make the thread want to be readable, like-able. Ask yourself, would you read this thread?? and with yellow highlights that no one can even see????????
You also need to post if you're phone is stock, what rom you are on, what version..

Sorry,thought they yellow would highlight it but it actually made it worse . I think the red is better with the whiteish background....
This is a stock version, I updated the phone to 2.2.2 but i factory reset it and now it says i have 2.2.1 even though i have 2.2.2 features like Wifi Hotspot,Wifi Calling, and images for contacts on messages...
im not sure, i havent had stock phone in a lonnnggg time..
Hopefully someone else can help you out

This is a hardware problem (the repeating screen) that seems to be happening to many people. (it happened to me before which is why i replaced my previous slide). After my 2yr contract is done, im gonna stop getting phones with keyboards because this also happened to my previous htc slider phones

So it's actually because of the sliding part of the phone ?
I'm not surprised, this phone was pretty cheaply made imo, literally a piece of crap :\

Oh I see, well I tried to get it replaced but HTC was a bit suspicious when they wanted my credit card before anything ......
I have the same issue with my phone
As I was looking at your photos I realized I have the same issue going on with my phone. Does anyone have suggestions on ways to fix it? Personally, I do not believe it is a hardware issue. I do believe it is more of a software issue. That update that HTC offered is definitely screwed up! Ever sine I updated my phone, all of these problems started. This problem did not occur beforehand! My phone was working fine - before this "software update."
Same Problem
I had the same exact problem with the Repeating Screen (and completely agreed about the camera lol). Yesterday I tried demonstrating to my friend the problem, and permanently blacked out my screen. Now, the phone works in the sense that it receives calls, the home keys light up, and the camera still takes pictures. However, with no screen to select any options or perform any functions, the phone has been rendered completely useless. I, too, would like to figure out what the problem is and if there is any possible fix.
Sorry I couldn't be of much help. Just know you're not the only one lol
My girlfriend had the repeating screen issue back in May/June of this year. It was more than likely a software issue, because it became incrementally worse as the phone opened and closed until it came to a point where absolutely nothing could be done when the phone was moved horizontally.
I had T-mobile replace the phone at the time. Unfortuntely an idiot I work with who was supposed to mail it back didn't, I got stuck with an extra $360 on the bill.
Worked out paying for the phone with them yesterday morning, this morning my girlfriend messages me to let me know the screen is acting up again.
Potential Fix?

I would recommend replacing your flex ribbon. It worked for me, and from other threads I've read, I believe it's the cause of these issues. It's a pretty easy fix ( coming from me, who's far better at breaking electronics than fixing them, lol ).
Here's the flex ribbon that I bought off of Ebay ( it's the cheapest I found and it comes with the tools too ):
http://www.ebay.com/itm/170647168235?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
And here's a good video on disassembling your Espresso:
http://www.youtube.com/watch?v=-jgFHuVWlig
P.S.: I'd recommend being more delicate than he was with the volume ribbon though, as mine seemed very frail. Also, this video is for replacing the digitizer, so you only need to follow it to get to the flex ribbon.
A month ago, I had issues very similar to the ones you posted. Sliding my keyboard out ( in any way but gently ) would occasionally split the screen or freeze the phone. Even without using my keyboard, the phone would occasionally freeze while "settling" after the boot animation, and sometimes even during the boot animation. Slowly, those "occasionally"s become more and more frequent, until my screen just went black one day. The phone still seemed to work ( lit up when turned on, made sounds, etc. ), just the screen seemed dead. Figured that I was having a combination of software issues ( the random freezes ), and hardware issues ( split & black screen ), but replacing my flex ribbon suprisingly fixed everything.
This is what worked on my MyTouch 3G Slide
i just keep sliding the phone. and turn off the screen then turn it back on. but not turning off the phone.

[Q] Touch sensitivity issue cause?

I've been reading through the previous threads and I'm still confused if the issue is hardware or software related. I have the AUO panel and have broken swipes, and times where I can't scroll properly. This has been going on a couple months now and it's getting on my last nerve since it's frequently happening when I need my phone to work properly. All this time I assumed it was software but a couple threads mentioned it was hardware. Trouble is, some people with the JDI screen also have issues so I don't understand. My question is, has anyone ruled out software by flashing an AOSP rom? I'd rather not send this to Sony if at all possible since they don't cross ship and I'd be without a phone.
I have rarely an issue with the touch screen, when swipe up or down, it doesn't swipe it acts like I've just touched (clicked) once the display. I think it is a software issue, because in my case, if I turn off the display wait for 2-3 seconds and turn it on, it works with no problems.
Can you point me please to other threads that have this issue in discuss?
Thank you!
Have you removed the asf from the screen and placed an actual screen protector on it? I found that this really helped with the weird screen issues.
I have a screen protector over the ASF. But that has nothing to do with my issue, because, like I said, when I turn the display off, wait 3 seconds, and on again everything is working normally.

Yeah, I reboot usually and the issue temporarily goes away. Then it will come back a day or two later. I'm afraid to remove the ASF because I've read some issues with goes touches even with a screen protector. I just want the issue to be fixed... I was thinking of flashing a AOSP rom but wanted to see if anyone with that ROM had any trouble or not. Maybe the L update in January will fix things.
Here are the resources I've read on this issue:

http://johnhaller.com/blog/2014-03-06--sony-xperia-z1-z1s-touch-screen-issue
http://forum.xda-developers.com/showthread.php?t=2770293
I have rarely that issue, like I said I just turn off the screen, and after 2-3 seconds turn it on and it's gone. I'm sure this is a software related issue.
If it helps at all, I never had the issue in the two weeks I tried an aosp rom. However the camera and battery life were a bit lacking so I'm back on a stock rom.
I haven't have the issue too in the past weeks, I've wiping cache and dalvik cache pretty often , because I've installed some system apps. Anyway I will really want to know the cause of this
L.E. I'm still on stock firmware.
L.E. 2 : The Glove mode function, in the Settings-Display menu has an application or something? Has a file redirected to it? Is there in the phone's system a file than can be edited or deleted or something for the glove mode function? Maybe we will find answers there.
I'm not sure that I've made myself understood with the question.

My Z1C seems to have a similar case of faulty display as described in some other threads here, but actually a bit different. The phone is stock, not rooted, running 5.1.1
Whenever I do something, there are ghost touches in the upper quarter or third of the screen. They only happen when I am not touching the screen myself. It happens no matter what I do. When I browse internet, it clicks links, when I scroll contacts, it calls people, when I am on facebook it gives likes etc... It seems like the more demanding task the phone is performing, the more ghost touches.
I turned on the developer settings and the "show pointer location" option, which leaves track of the last touch on screen, so I can research the issue.
I found out that when the phone is on home screen, it happens very rarely or not at all - the track of my last touch stays until screen turns off.
When I jump into the touchscreen service test, it does not happen at all. I can draw a line around the whole screen and it stays higlighted indefinitely.
In lock screen, it also doesn't happen.
I tried it in Sketch and it confirmed what I thought, when I was just sketching, from time to time a dot appeared in the upper part of the screen, but when the phone was downloading or installing in the background, the screen literally had seizures. I touched and released and then a storm of dots started to appear around the top part of the screen. It stopped after 5+ seconds, and after another input from me, the screen got another fit, drawing more dots.
I don't have any experience, but I think that since the problem doesn't happen constantly and it doesn't even happen at all in test mode, it could be a SW mistake.
I have found this thread https://forum.xda-developers.com/showthread.php?t=2691849 and I'm willing to try, but 1) my phone is still under warranty and 2) I have never done a root so I am not too eager. Do you think I should try that? Or has anyone found another solution for this problem?
Thanks.

As You have warranty, I would strongly suggest that You go for a repair. I had the same issue in beginning, ghost touches appearing randomly, going away only after reboot. I was rooted and xposed, so went full stock without restoring any apps or data from internal storage, yet the problem remained, thus ruling out the point that it was software problem. And then after a week or so, that much part of screen stopped responding to touch entirely. You can see details over here, Another user had same problem as Mine and had the same end result,
OK then, I'll go for a repair. Thanks for the tip.

I am having exactly the same behaviour as you described .
Ghost touches happening on the upper part, and triggered when a demanding task is running.
Actually I didn't realized completely about this, I thought it was just random, but right now after I saw your post, I tried an app similar to Sketch while upgrading apps or playing a video in the background. And dots in the upper part start appearing crazily.
Did the phone repair solve your problem ? Mine is not in warranty, so I'll have to pay for it.
But also in my case, before this thing happened, I got some water damage and that upper quarter of the screen stopped responding.
After replacing screen+digitizer I got this very specific behaviour you described.

In my case, I realized that I bought (probably) a badly re-fitted phone. Display's backlight was visible around screen panel edges, where I'd say it shouldn't be visible at all. I decided to return the phone and got a refund.
Sorry for not being able to help you.

Ok. The aftermarket screen I got has that issue with the screen edges also. Very probable you are right.
In my case I water damaged myself. It seems that after 2 years of intensive use, waterproofing is gone, by accumulation of slight hits or so, never had a single crack on the screen. I read many posts reporting this happening, even with much less use time.
Too bad, I loved the phone, but I'm afraid that sending it to repair will mean to change the PCB or similar for a complete fix, which can come to a ridiculous price.
Seems it will be time to move on...
Yeah. If you want it fixed properly, you'd need to send it to Sony, and for the money it would cost you, you can probably gen a new phone. Sadly, similar phones aren't made anymore.
