(SOLVED) Serious screen problem, please help!

Looks like it was my generic charger causing all the problems all along...
Too high output (6.5VDC where it should be 5VDC)
Ordered a replacement, hoping for the best.
Thanks for all the help!
Sometimes my touchscreen is just perfect. Lately, it's driving me nuts!
When I hold my finger on the screen, the touch screen registers rapid multiple touches. Possibly as many as 10 per second.
This makes dragging and long-press actions almost impossible. Scrolling is very hard and typing is a PitA.
The problem goes away at times but keeps returning. I'm not sure if I had it before the recent update.
At first, it seemed like rebooting helped but today it proved useless.
Anybody, please help!!!!

Do you have a screen protector on the screen? Sometimes the cheaper ones are too thick and the screen doesn't register touch like it should.

Just the one that came on the phone.
Like I said, the phone works beautifully some of the time but registers multiple contacts other times.
I suspect software but it seems I'm the only person with the problem...

do you have a warranty.... sounds like a hardware fault to me.... the only way you can prove it's software (or not).. is to do a factory data reset and then run it with the standard basic build for a few days.. see if you still have problems when you don't have any other apps on the phone.

Do you have wet fingers when you experiment this behaviors?

Happens to me too. I figure its due to gunk on the screen like water, sweat your gf's makeup (a major one)

This happens to me too.
Only started happening since the last update so I just assumed it was a bug in the new firmware. It's like the phone lags and then catches up with itself, very annoying.

I think it is since the update. I'd better reset the phone using SEUS and see what happens.
@ everybody, believe me, I have had the problem through a variety of circumstances and no problem with sweaty fingers etc. It seems pretty random!
I don't have a warranty so re-install here I come!

I would definetly try the factory reset first. I have had similiar issues but its only been while typing quickly. It lags a bit and then it all shows up on the screen plus a few extras of whatever the last character I typed was.
I did read somewhere, can't remember exactly where, that because our screens are capacitive they can malfunction. What I mean is this:
"Surface Capacitive touch panels: a layer that can store an electrical charge is created on the glass panel. When a user touches the monitor with his or her ungloved finger, a portion of the charge is transferred to the grounded user reducing the charge on the capacitive layer. The controller calculates, from the differences in charge at each corner and determines where the touch occurred."
Sooooo if say the ground for the screen is damaged then it will not register your touch appropriately. Hopefully it just requires a reset, cause the latter I think would be a tougher fix.
Let us know

dfan, is it happen only when you charge your phone? What charger are you use? Original?

I did a restore but no change, issue still there, it doesn't happen often though.
Dose seem like a bug and it never happened to me before the last update.
Also it happens to me when not charging.

very bad.. you cannot drink a cold coke and use the phone. I think that it is a hardware related problem. I was trying to reproduce the same with N1 and Legend (with my fingers flooded) without problems. So.. guys with hyperdrosis keep away from this phone!

No it's not a hardware problem as it only started happening with the last update.
Remember the x10 uses different software to nexus one or desire so can't compare with them.
I believe it's the software lagging, this update is faster overall but just lags occasionally, maybe the next software update will fix it, and if not the 2.1 update should definitely fix the issue.

Are you pretty sure?

Tested... it is present on old roms

Well the old roms were laggy as hell anyway. It seems like classic software lag so I still think it's software.
Maybe when 2.1 is released we will find out, or even better when we get stock android running though root, that would clear it up once and for all.
My iPhone 3g also suffered from similar lag issues.

Hells yeah I don't want a defective screen or this thing is done!
regarding your first comment, this is not lag. It is like I had a turbo button. If I touch for more than 1/15 sec, I get 2, 3 or 4 letters.
instead of one long press, the screen continually registers new presses, no matter how firm my touch is.
Imagine how much fun it is drawing the unlock pattern when my phone's in a bad mood...

That dose sound different to the small lag I occasionally experience, very odd.

I've reinstalled the FW and it didn't fix it.
The other day I had 5 straight hours of rapid-fire screen during which I couldn't even unlock the phone.
Gonna have to send it in for repair. Anybody know how expensive S-E are for repairs? Is it even worth doing?

I have narrowed the suspects down to my generic charger.
The charger I bought outputs over 5V (claims 6.5V) which seems to be the problem since I don't experience the issue when charging from a USB port.
New charger ordered, fingers crossed.
Thanks for all the suggestions!

'Splodge' on screen

Splodge, was the only way I could describe it...take a look at the attached photo.
I'm certain I have seen someone else post this before.
It just happened randomly! Was fine all day yesterday, then picked my phone up to answer it last night, and after the phone call had ended I saw this on the screen...
Touch screen still works, and you can still see underneath it, its less visible when the back light is on. Of course when it's off, you can see the effect it has!
So...what is it? Easily fixed or what?
Like I said, I'm sure I have seen this posted by someone else before...

Hehe... nice one. It will most likely disappear if you gently pull the glass with a suction cup.
Brgds... /Tubgirl

Suction cup thing works but then it comes back.
HTC said it would be out of warrenty :S and they would have to look at it first.
O2 however, said if its in warrenty (which it is) then they will get it repaired and supply a courtesy handset while they have it.

i had one the same size it has slowly gone to half the size 5 pence piece but o2 said its not under warrenty and i work for a major phone retailer and my repairs guy said it may so im very unsure wuld have re flash it as its hspl grrr

interesting, well I'm taking it to the O2 store next week, so will see what they say, will keep the email i had off them saying they will as backup!
It has reduced in size, but still has the rainbow pattern in the middle.

I had a similar screen problem however it didnt look anywhere near as bad as yours. Mine had slight discolouration mostly noticable on white backgrounds. Pressing the screen a little bit harder than normal created the sort of effect you get when pressing the screen of a calculator (dont know what to call it) I took mine to the o2 shop with a different fault and also mentioned this fault. I got it back 6 days later but they hadnt fixed the screen problem. I sent it off again then and there and 6 days later i got a new phone.

O2 now have my HD2
Been given a nasty old Nokia phone as a temp...forgot how small some screens are...lol
should take 7-10 days they said...so fingers crossed...

Any way of fixing this problem without sending it back as this has happened to my cousins HTC HD2, kind of glad it didn't happen to mine lol, any quick fixes to know about?

I've had the same with my HD2.
They fixed it for me (new screen)

Was actually thinking about this, then tried to figure out how it happened, he goes it was one of two things, since he considers himself a bit of a playboy lol, he tells this tale of a girl sitting in his lap and it happened or could have been wetness (kind of goes hand in hand don't you think lol).. how does this problem usually occur?

LOL!
Well anyway! For me it was very random. The phone was fine all day at work, I had a phone call in the evening, after the phone call I just looked at my phone, and there it was...
Some people have said its caused my the heat of the battery and signal, dunno.
Its a very thin space between the battery and the back of the screen, so maybe thats true.
I can't see how over pressure can cause it as its a glass screen, and glass doesn't bend like plastic.

I had a smaller of these newton rings at the center. Much smaller than yours.
Suddenly one day it disappeared.
It was during summer and I thought it was probably because of the heat.

Interesting, he did always complain about his battery overheating or when on a phone call, the phone temperature increases rapidly, guess that was the cause, at least I get to tell him some good news, he can go to spearmint rhino as much as he wants lol

Hasn't arrived at the store yet, waiting for a phone call, fingers crossed for today! that would be exactly a week.

Hope its fixed soon for you, its interesting about the battery and heat, my hd2 gets warm below the battery and that is also below the main area your problem is on, I suspect its down to a screen fault myself.

Hopefully because I know how it feels like to be without the beloved HD2, I had to last two weeks, no matter what phone you use as a substitute, for some reason, it just cannot compare!

[Q] Misbehaving N1

I got my AMOLED N1 back in Feb 2010.
Unlocked bootloader, rooted 2.2.1.
The problem which existed from day one but showing much more often these days, is that after running an app (e.g. Market) the touch screen misbehave. It either does not register the touch, or maps the touch about an inch lower from where it should be. The phone has plenty of free memory (internal).
The problem is more prominent since the 2.2.1 update (but I am not sure it's related).
Does anybody else experiencing this?
TIA

Most people!
There is no solution other than the temporary fix of turning the screen off and then on again.

Yes.
I'm getting really frustrated with the N1 due to the ****ty touch screen.
I had a play with my brother's Nexus S.... SO much nicer and smoother. The touchscreen on the N1 is abysmal and shocking!
I've also noticed "freezes" in the sense that the display won't come up - only the touch screen buttons light up and then slowly fade off.... only way to recover is to pull out the battery. Really annoying.

Thanks DirkGently1, itay1,
Is there anything that can be done to fix this? e.g. replace a part (whether under warranty or not)?
It is actually becoming hard to even use the N1 as a phone or for text..

oh well...

It sounds like yours is worse than the normal problem. My screen will only mess up once every few days, some people have gone months, some a few times a day.
But if your phone is unusable just get it replaced under warranty.

My first experience using Android was turning on my Nexus One and encountering this issue the very first time i had to use the screen! The device i have has had this problem in varying degrees since i got it. Very bad to start with, not so frequent after i sent it back for repair.
Take a look at the poll from my own thread about the issue...
http://forum.xda-developers.com/showthread.php?t=878477
Pretty commonplace problem, which along with the power buttons failing detracts from an otherwise great phone.

Blame HTC, I had this issue on my first N1 earlier last year. I would turn the screen off then turn it back on.

I find it behaves better when the screen is clean. Perhaps finger grease can confuse it... it might be *that* sensitive.

I flashed the frg83d update this morning and I've gone all day without the crazy screen thing and I'm loving it lol!
*knock on wood *
Hope it stays that way!

@DirkGently1:
I've added my vote
@itay1:
I was just about to write the same thing. It is much better after I've cleaned it (which I didn't for a while)
I am not using any screen cover. I never did. But maybe there is a cover that helps. Those of you who never suffered from this issue, do you use a screen cover/protector? which one?
Also, maybe the issue is intensified by how dry (or not) our fingers are compared to others..
@dusty-:
Do you mean frg83g? frg83d did not help my case. sorry..

Yes I meant frg83g lol

does z2 has touch problems?

im now on z1... and i have that problem when touch screen takes life of its on and starts to go around -.-
same thing is on z1s and z2 tablet...
how about z2 the phone?
so far so good?

Any liquid on screen creates this problem for me with th Z2. It does not matter if its moister, sweat or rain drops they make the screen cray cray only way out is to wipe the screen.

Not only..when i chat more than 20 minutes some of my finger touches are not recognized and i must to touch the screen with my other hand to rec.it.. its strange.. .314.. hope Sony will fix it. (hope its not something with the metal frame and sensor confusion).

This is true of every capacitive touch screen I have ever used.

I owned Z2 and Z2 Tab. If you leave so munch oil or finger-print on your screen it will cause touch problem, wipe out and everything is fine.
You may try tempered glass or mate screen protector to reduce this problem.

This is exactly why I never wanted to give up my slide out keyboard phone. I wish more people were like me, I kept holding out for someone to make a respectable keyboard phone but I guess there's no market. I am not a fan of using the touch screen for entering text and numbers. Today was a prime example, my morning was rushed and I am fumbling to try an enter a new hires phone number. So frustrating, I swear it was the 15th try that I finally got it! Here I am fumbling with a phone while trying to direct workers to their tasks and deal with production and management at the same time.

still holding ontu my n900 and n950... my z1 died and got new under warranty... wanna sell it and go for z2 if it doesnt have touch problems like z1...
rocking n950 for now...

yes it does
thats my z2 has ghost touch i dunno what to do to fix it yet

old firmwares seem to bring up alot of ghost touches
i had very little on 314 firmware
also on my older units, i had them regardless of the firmware

I remember back when I had .55 the screen sensitivity was pretty bad, especially during phone calls when it suddenly turns on when it shouldn't, also double tap to wake wasn't as responsive. After upgrading to .314 it seemed to fix those problems

I had this problem with my Z2, too.
Then, after an unlucky drop, my screen was broken, so I got the screen repaired. After approx. a week my screen got more and more its own life. At the end the phone was totally unuseable. The repair shop replaced the screen again, since then it just apperars from time to time like before.
I think Sony has some issues with these screens. My S2 which I had before the Sony had never such issues, even if the screen was quite dirty. Maybe thats why they introduced the Z3 so fast?
Here you can see the "amok screen". I enabled "Show touch" in the developer options.

Paid for repair 225€ at a shop in Berlin. No official repair shop, in this case it would have been about 350€. However, it is no longer waterproof.
But they replaced the defective (ghost operated) screen without any questions at no cost.

Kinda too much, but then again Sony in Serbia replaced my back cover for 50e, but when I come to think about it, it's probably because the average salary here is around 300e

Weird screen flickering

Hello,
This is my first post in this part of XDA.
My wife has an s7 Edge and the screen started flickering. I got out of this state messing with the power buttons etc. Mainly getting the touch screen to unlock the phone and it somehow cleared right up.
Is this a software issue? The screen when it came back is working as usual when I restarted the phone it became crap again.
Im think it maybe the lock screen causing this, I never heard of parts being corrupted.
I've attached a little clip of the screen.
Thoughts?
Thanks in advance!

I have never seen this happen before. If I were you I'd flash a new ROM on it in Odin and if it still happens take it to the Verizon store.

Forgot to mention, it's not rooted completely stock.
So screen is messed up?

I had this issue. My phone fell from less than a foot off the ground and landed on the corner. Barely any force, but after that the screen would flicker intermittently. For a day or two it would come and go, and then it became permanent. It looked exactly like yours. If your bootloader/recovery/download mode flickers then it is a hardware problem, since the ROM isn't even loaded yet. With Verizon, your phone is fully covered from manufacturing defects for one year, so you should be able to get it replaced. Sorry bro. Wish I had better news.

Honestly with a screen issue like that, I really recommend taking it to the Verizon store and asking them about it. It seems like a hardware issue to me but that's just my opinion.

My screen has done some weird things as well fresh out of the box. I would have random areas of the screen pixelize until I smack the back of the phone. Even after root It will randomly do it every other month. My father in law had the same exact issue you're having. He brought it into T-mobile where the screen literally failed and went black in the employees hand. Neither his or my phone has ever been dropped. This is definitely a hardware issue. It's almost like a bad connection between the LCD and main board. Make verizon get you a new one before the screen goes black!

Okay...
Is it okay to say I can get a new screen and do that repair myself?
I wanna make sure that the issue I am having is just "buy a new screen and be good to go".
Thanks for your time!
