screen problems?

i got my td2 just about a week. yesterday suddenly the touchscreen didnt work at all anymore! i was taking some pictures and then it stopped to do anything on the touchscreen. i rebootet the device few times but no go - even removed the battery but didnt work anymore. then i left the device a few minutes without battery and when i tried it again it worked. this scared me a little... because without touchscreen u are really lost with this phone.
ohwell.. i hope this doesnt happen again. but i actually got another strange thing here:
if i look into the screen from the side.. i can see a strange glimmer sometimes. it looks like oil in water... it does glimmer a little and its not visible all over the screen but the part does even grow. i noticed this yesterday and it was like 5cm long and 2cm width. but now its almost on the full screen and it looks like the effect when u press on a LCD screen really hard. but it appears without doing anything.. does anyone have that too on his TD2??

same problem here. its the device of a friend. one week old. but we didn´t managed it to bring it back to life again...
no we will try a hard reset.
battery was out for ar least 30min wizhout success.
even noticed some glimmer at the screen. hard to describe. like liquid between sreen and screen protector.... but only on those parts were we tapped on the screen...
no we try the hard reset - i´ll report how it worked.
somebody else with that problem here?

ok we tried a hard reset - no success. screen is dead. no way to setup the device. no reaction of the touch screen. will go to the o2 shop tomorrow and bring it back...

wow.. at least im not the only one. my screen is working again but the glimmer didnt go away. also today appeared one more defect on the screen - it looked like the protection plastic is moving, but then after some tapping on the screen it went away again. very strange!
the glimmer looks indeed like a liquid between the screen and the protection. sometimes its almost not visibe and sometimes its really good to see. i wonder whats going on here..

hey i just found something out!!
my screen has something like little bubbles under it when i do touch it on a certain area. when these bubbles are visible.. my screen does not work anymore!! then i can clean the screen a while with a tissue or my tshirt or whatever and the bubbles go away - as soon they are not visible anymore the touchscreen works again!!!
im tryin now to give that phone back and get a new one. i dont even have that phone 1 week!!

I have a Diamond2 with the same frozen screen issue. The screen just did not react to any tap. Soft reset may put it back to work again, but the symptom repeated after some time. Even hard reset cannot rectify the problem. It is hardware defect. Fortunately it is one week old and still within the one-to-one exchange policy and I can take back to the shop I bought push for an exchange. Having email HTC and they just ask for service check and refuse to exchange a new one. If you conduct a Google search of freeze screen, you may locate a lot of touch screen issue but only very limited solution. I suggest you to have the device exchange than going to repair.

Does it look like this: http://forum.xda-developers.com/showthread.php?p=2557175#post2557175???

Hi, I am experiencing the very same problem. Touchscreen stopped working. Taking out the battery for 5 minutes fixed it. But there is a oily liquid now beneath the screen. My device is 5 days old, this should not happen
Taking it to the shop on monday.

we tried everything but without any succes...
today we gave back the phone. it was within the one week limit. but there is another limitation: 15 minutes airtime! i said to the guy in that shop: when he can show me the airtime, we keep the phone - because than the screen seems to work again... )
but no problem they exchanged it against a new one! good service, very customer friendly at o2!

I encountered this one day after getting my unit. I got a replacement. It seems two layers of the touch screen is "stucked" together. Use scotch tape to lift up the area and and the touch screen responds. But the next time you press on the screen it will get stuck again.
So get it changed.

wow
what a great idea... never ever thought of that... *lol* but when you buy such a sophisticated mobile it looks very unsophisticated to lift your screen with scotch-tape everytime you tapped on the screen...

kinda yes. but not that big and after cleaning phone with a tissue it goes away. i will get a replacement in a few days.. hope this doesnt happen again - but shop told me it seems that there are a few ppl with that problem on td2!! :-(

ok i did get a replacement now and all is fine again. but i think i know what caused the problem.
actually i had the phone always in my back pocket of my jeans. this is not a very good idea when you sit down. the phone gets some pressure on the screen and my screen actually was lowered into the case a little bit. you can see this from the side. that did cause the air under the screen and also the oily liquid that sometimes appeared. so i think the screen felt into the phone case and this was causing the problems. my new phone does not look like the screen is lowered - its totally flat. so i will take more care and not using back pocket of my jeans again to put the phone in

I hope you are joking... I mean one can't be serious about carrying a touch screen device in a back pocket of his jeans. Are you even surprised about what happened to it? In fact I'm rather surprised you got a warranty replacement. There is a thing called User manual that comes with the device a it is saying 'Always remove the device from the pocket of your trousers prior to sitting down'. Yu are really lucky indeed you got a replacement....

well aint a mobile phone made for putting in the pocket? this is not my first phone and i never had such a problem even with a touchscreen phone. its not like i did sit on it with full force or something.. just had it in back pocket during cardriving. you can easy do that with any other phone without breaking it...

that's exactly what's it's not - it's a pda phone and it kind of makes sense to treat it differently from normal mobiles which can withstand all sorts of abuse. also if they ask you specifically not to do something because it can damage the device - and you do it and then you are surprised it happened. it's written there for a reason. they surely know that for many people it will be their first pda phone so they don't have much clue how to treat it...

[Q] Broken Screen

Hi there, I know there are other threads on this, but I've got two questions;
I might be able to claim a repair on insurance - the policy doesn't state anything about rooting voiding it, but I'd want to play it safe and flash back the original RUU - now, the digitizer works on my phone, but the LCD is totally shot, can't read anything.
It's been a while since I flashed the RUU, so is there any point where you have to press a button or something on your phone to advance? is it possible to use ddms while flashing the RUU to see what you're doing?
Also, if I can't claim this on insurance, how hard is it to replace the screen yourself? I've seen a "genuine" (hmm.) LCD/tools set on ebay for about the same amount as my insurance excess, so this seems like it could work (if it's easy enough!).
Thanks!!

I've not done it personally but I have seen the guys in the phone shops doing it.
It's not that hard, but you have to know what and where to remove. Just go slow first.
pardon this but what is ddms?

Hi,
I have flashed RUU for my Tattoo at least twice. And as far as i remember there is no point you have to do anything on your phone. It will reboot (into fastboot i think). You will se progress on computer screen.
By the way, how can the LCD be broken and the digitizer not? Is the lcd shattered?
This is against laws of physics!

Oh, maybe I got the letters wrong but ddms is part of the android sdk, so you can take screenshots on your computer - also handy if you've broken your screen and need to know where to press.
As for defying the laws of physics, I guess the Tattoo is more special than we thought! the lcd is showing up loads of black/white cracked patterns (but a small it at the bottom works, so I can just about make out my dock. )
Thanks, insurance guys seem to be a bit more helpful now, so hoepfully won't have to resort to doing it myself.

Just in case anyone else has this problem, found this nice photo-guide to unscrewing everything: http://translate.google.com/transla...acenter.ru/razborka/htc_tattoo/&prev=_t&twu=1
haven't got round to it yet, but should do after exams.

Thanks useful info.

I have opened and dismentled everything my tattoo 3-4 times refering the guidlines. It is really helpful.
I was trying to resolve a touch screen problem. My phone acted like something is always touching at a point of the screen, so, I couldnot able to select a thing correctly and it is worst while typing using screen keyboard. So, I disassembled my tattoo and clean everything inside and assembled again. It seems working correctly for few hours then the problem reoccurred. And I disassembled again and again.
Atlast, I found out the problem was just on the screen protector, I have removed it and resolved the problem. Funny problem but it is worth all those efforts.

Bad Digitiser
Recently the Digitiser of my phone went bad. I tried flashing back the Stock RUU but did not succeed since it was not able to detect my phone. Then I just flashed back the backup of the stock ROM and took it to the Service Center. To my surprise the person didn't even check whether the phone was rooted lr not. Since it was out of warranty I still had to pay I still had to pay $45.

An confusing issue regarding the infamous phone screen - Presses itself erratically

I want to give some context.
I have owned my Z1 since release on a contract. I have previously had the screen replaced twice and it worked fine afterwards.
However, I had dropped the phone resulting in the top of the screen cracking. Got it replaced by a local phone repair shop.
The result was a new phone screen, a white edge just over half way down the screen might be worth noting. The repair man said it was a warranty sticker on the screen they put in. (Sounds silly)
Anyway, the resultant problem is not exactly like what i've seen on many threads.
My phone now decides to press itself erratically. Usually after swiping and trying to press delete on the keyboard would it start acting up.
My remedy: Hard reset(Didn't work), factory reset(didn't work), upgrade from 4.4 to 5.1(I think, newest software) and to my surprise the issue remains. So after the repair man replacing the screen twice and ensuring that i'd done my best with little to no phone knowledge, I still have this problem.
There's many threads detailing problems, some linking to apk's that are "calibration software", some that say you can change calibration.ini but no helpful replies or expanding info on the threads.
Can anyone tell me if they've had any luck with this or anyone who has knowledge of what I should do next (E.g "there's no fix guy, you'll have to sell it and move on") as i'm starting to assume these screens are very tedious to deal with

Remove the plastic protector and put a tempered glass protector

Screen Flickering

Hey guys
I have a very strange problem with my Huawei P10
About 2 weeks ago, I noticed that two purple horizontal stripes are appearing in a 3-4sec sequence
Normally, I would immediately ask for a repair, but there's a thing which persecutes me: it only happens when I don't touch the screen for longer than 3-4sec
When there's a continuous contact with the screen (e.g when writing a message) nothing happens, everything is fine and dandy, but whenever I leave the screen for itself for 3 or more seconds (e.g when watching a movie), the stripes start to appear every few seconds, and continue until the screen goes dark or until I touch it again, but after touching it it still takes only a few seconds for the stripes to sequentially flicker again
Here's what I've tried so far (no result):
- safe mode
- factory reset
- cache partition wiping
- cord input deep clean
What may be the reason?

Hey.
It's 100% a board or Display issue. send it for repairs. but i believe maybe you've dropped ur phone. Anyways Huawei knows better.

It's quite complicated
I once dropped it, but even after that, the previous LCD worked fine, there were no errors other than broken glass, so I guess we could exclude a board issue and lean toward your second option, as now that the LCD has been replaced, the fault occurs
What's more, I noticed that if I press the Home Key, and then put my finger in the bottom right corner and hold it, I can still use the whole LCD space without the flickering (I need to press the Home Key first so that it works after I hold my finger in the corner)
It's like the LCD needs to be in contact with your finger all the time to avoid that, which has led me to an idea: would a tempered glass solve that maybe?

I can't really answer for sure but i believe if there's a Huawei service center in your city and you try to fix ur broken huawei, your wasting your time. Whatever solution u apply on ur phone its just gonna be temporary since u hide your problem and not solved it.

I still think (or should I say believe ) that there's a solution which doesn't involve another screen replacement
As for your "temporary solution" mention, I guess if I found one, it wouldn't be temporary, since the fault doesn't progress, it's been the same for a month or so when it first occured, which gives me another reason not to replace the screen and keep looking for other possibilities
I don't need a Huawei service center, I can replace the LCD myself (didn't do that the first time though), but it still involves spending money, whereas I've been looking for unpaid solutions the whole time; getting a new LCD is an extremity

You can ask them to diagnose it and tell you about problem noone makes you pay for a lcd. And after reading your message over and over (And since i repair TVs and everything with electronics inside) i think it also can be your touch or display controller ic. Mostly it could be from touch ic since screen works fine while its in touch with something. But someone has to try your lcd or mb on a healthy one to make sure. which you can't do nothing like that. or do you?

@fengels did You bought original lcd, where can I buy it in good price?

I know this problem from older galaxy series like s5. The fix for this most of the time was disable auto brightness or higher the brightness on auto brightness. Don't know if this is the same problem, but it could be a try. Also don't know which cause this strange problem. Hope it can help you

No, it's a different problem, in the galaxy series the whole screen would flicker, whereas in my P10 it's only 2 horizontal stripes appearing in a 4-5 sec sequence whenever I leave the screen untouched for longer than 5sec
Playing around with the brightness doesn't solve that unfortunately, actually no in-device settings do, as I've tried almost every single option which is screen-related, like switching the eye comfort mode on, but still no result
The main reason why I'm still looking for an unpaid solution is that apart from this one error, the phone is like brand new, everything works fine

ok, so if I understad the problem shows up after you replaced the LCD display? So do you really think is more software related than hardware? I personally would send it to diagnose and repair.

The thing is it didn't show up immediately, I had used the phone for some time with no errors before it first occured
Also, since the new LCD was set, I haven't done any physical damage to it, I've never dropped or sunk the phone
Since you guys mostly advise me to send it, I guess that's what I will have to do

While you were replacing screen, did you turn your device off and disconnect the battery? and i think cleaning all cables coming from LCD and related sockets on motherboard can help. Use thinner or alcohol and if you wanna use thinner be careful so it wouldn't touch anything except golden contacts. Thinner is dangerous and affects ur phone color and plastic parts.

I did turn the device off, but I didn't take the battery off, since it's strongly glued to the phone's body, and I didn't want to damage it
Anyway, could not taking the battery off really be the reason?
As for cleaning, I did it by simply blowing out all the potential dirt, I'm inexperienced in thinner and alcohol cleaning

I am not sure butbon some phones it damages screen. I've seen this on laptops. But anyways its done. Open ur phone and use alcohol. put 2 drops of alcohol on each socket and flat cable connectors and brush it with a soft brush. u don't want to bent any golden contact. It's last thing u can do to fix it without paying for hardware related stuff.

Questions about my cracked screen

So I'm curious, my screen is cracked and I'm pending a replacement and I was wondering if replacing the whole display is absolutely necessary, it was dropping from a whopping 8 inches and got a nice cracked corner , well when it came to it it made me upset but I went back to playing cod mobile , but then I turned off the display , and turned it back on later and realized my screen was discolored and wacky which I would assume points to a bad amoled ? Is that correct , it still works after a reboot but I don't want to keep the display on 24/7 due to. Burn in / batterlife issues etc I was wondering if it is possible to find some kind of software trickery through rooting perhaps or idk , my question is what causes it to work perfectly fine after booted and then go wacky when turning the screen off and back on

Seeing as the display panel itself is probably heavily damaged. There is nothing software can do to help rectify this issue for you.

I'm not looking to fix it with software moreso I was asking what causes the display to work perfectly fine until I turn the screen off and back on , and if there's a way around that like perhaps refreshing the system ui or some kind of quicker restart I can do with root or perhaps someway of just keeping the screen full black and turning the screen off without actually turning it off, I'm sure there's a few way to lessen the issues crap before I order the screen, I mean it's just a small crack in the bottom right corner

youd be surprised how often that happens. Go to sammobile.com/firmwares and download the latest firmware for your phone and flash it in Odin. Use the HOME_CSC to avoid factory resetting the device and see if that helps (probably wont) but at least you wont have to set it back up to check. It will be fairly instant gratification. If that doesnt work, flash the CSC, which WILL factory reset it. If that doesnt work, bad display

Replacing the whole display is not necessary no.. HOWEVER, it's much much easier to just replace the entire screen because most people don't have the correct tools to remove just the glass and even if they did it's still terribly hard to do perfectly! If the colors are not permanently messed up and rebooting seems to fix it then it's likely that if you update the phone it'll correct this issue but it's not guaranteed because the screen is cracked and the problem could be from the crack itself.
