Digitizer Malfunction - Xperia Play Q&A, Help & Troubleshooting

I recently replaced my digitizer and it registers but for some reason when touching the middle, it doesn't track the finger correctly and shows it going all over the place. Are there any explanations/solutions for this? I was on the understanding that every digitizer/LCD should work on any xperia play but i noticed the barcode sticker was green unlike my last digitizer which was white. Does that signify any change in the actual digitizer? and why does every guide separate 4g items?

You could have gotten a defective digitizer or just simply installed it wrong. Try re-installing or ordering a new one. If the problem persists you should contact the Manufacturer.

How often does this faulty digitizer stuff happen anyway? Also is it really neccessary to lift up the black safeguards(dont know the name) when installing the digitizer because i noticed it connects either way?
also is it possible/what are the chances it's the flex cable?

HTC EVO digitizer glass cracked:(

I have hardware version 0003, the display works fine just the top glass got cracked, can someone point me in the right direction for a new digitizer assembly? I found one on amazon new for 24$ but have no idea if it will work for my phone.0002 vs 0003 I read have different ribbon cables.
Sent from my EVO.
When this happened to me, I couldn't tell that the LCD had also cracked. I bought the digitizer only, and when I took apart the phone, I realized that I didn't have the parts I needed to fix it.
I can tell you that the correct P/N for the Novatel screen is 2V6A, but I am not sure of the P/N for the Epson screen. Check which screen you have by adjusting the brightness.
If when you adjust the brightness it switches with a fade effect, then you have a Novatel screen and you need the 2V6S ribbon. However, if it switches quickly and suddenly from one brightness setting to the next without a fade effect, then you have an Epson panel and you need the other ribbon cable.
So, I know it's been posted a lot in other places but I couldn't find like, a definitive answer as to if there are different digitziers? Am I just confused?
I would like to try and just replace the digitizer and glass over top of the LCD, my LCD works fine, the cracks are really thin and only a few going across diagonally. It fell from maybe 2 feet off my lap onto a parking lot surface.
I understand there is two LCD pannel types like you said, but are there two digitizer types/sizes?! for that ribbon cable.
I'm completely comfortable with taking it apart, I'm just worried I'll get the wrong part and find out the screen is also cracked and have to end up not using it for days until new stuff ships.... bleh
I've found digitizer+glass on amazon for 24-30$.
How do I adhere it to the LCD though, says doesn't include anything to do that.
EDIT: Found this gem: http://www.durapowerglobal.com/HTC-EVO-4G-Digitizer-Adhesive-_p_1166.html
Adhesive wont be a problem I just need to know about the glass/digitizer
EDIT2:
OKAY, if you want to ignore all i've said so far here is my real question of what I need to know.
http://www.durapowerglobal.com/HTC-...iginal-With-Installation-Adhesive_p_1103.html
Is there only ONE digitizer/glass piece on any given HTC EVO 4G? Or is there two different types like the LCD?

Digitizer replacement

Hi, has anyone replaced their digitizer on their desire z/g2? How did it go? It looks easy on the youtube vid.. have any problems? What way did you use to melt the glue? What digitizer did you use, where from?
Any info much appriciated as will be replaceing mine v soon due to 'invisible finger problem' that's driving me nuts..
Thanks..

Never done it on a g2 but should be pretty straight forward especially with a video lol. Use a heat gun to melt the glue, pretty much the only tool you SHOULD use to do something like that.
I replaced the digitizer on my third G2 after getting a refurb replacement from T-Mobile that had a black spot inside the actual digitizer glass, not on the outside or inside.
The process is very easy with the video, however, trying to keep dust and fingerprints from getting on the inside of the phone while you're trying to get it back together is a serious pain in the rear! If it's the same video that I watched, just use a hair drier blowing hot air to heat the adhesive on the inside of the digitizer and then pop the digitizer off very very slowly, because you don't want to accidentally bend the metal bezel around the screen.
You also may want to leave the original leftover adhesive on the inside, because when I cleaned mine off, light now always leaks out around the bottom edge of the digitizer, below the menu, home, and search buttons, even though I used the double sided adhesive strips covering the entire length of the bottom, so light shouldn't technically be leaking out. No biggie, though... it works like brand new, now!
Thanks for the reply.. I have seen that video and that's what I was using as a guide.. I ordered the digi today, should be here tomorrow.. the only thing I was wondering was the glueing process, as I have not ordered the double sided glue/tape stuff, as I was just hopeing to still use the original glue as I think you are saying.. I hope that works! Have to be careful like u say with dust/fingerprints etc..

Hmm, after reading your post again, maybee I should of bought the double sided tape afterall? Do you think the old leftover glue is enough for the new digi?
Many thanks..

Run over to radio shack they must have some kind of glue you can use lol. google cell phone screen glue see what info you can find.
Ok, just incase anyone is interested, got my new digitizer, followed the video, used a heat gun cerfully to melt the glue, pulled the old digitizer out, and used the original glue whilst still warm to hold the new digi in, as all of glue stayed on the case rather than on the digi, which was pretty lucky.. put it all back together and everything perfect, touchscreen back to how it should be.. cost me 17 pounds.

How was this accompilshed?
I replaced the touch screen as well and the problem persists. Plus I never ran into a part that required a heat gun did I use the wrong item?
A VERY confusing part is getting the midframe to hold to the hinge mounts. The side (black dots all down it) should overlap the stabilizer bar on the hinge. I fidgeted with it for hours until realizing it goes over, and inadvertently damaged the highly sensitive LCD screen, which resulted in me taking the whole thing apart again to replace the LCD and digitizer. UGH!
DO NOT get the cheapo digitizer on Amazon, look for one with gray spots where the menu, home, back and search keys are on the back side. The digitizers without them will not work when you swap over the white button caps on the back. I feel like this information is vital to anyone who is replacing their G2 digitizer, but most guides and videos make no mention of it.
I used a lamp to heat up the glass to remove it the first time. Took too long the second time so I used a hair dryer.

So which digitizer did you end up buying and which guide or video did you follow? I am about to tear mine apart and could use the info.

Hi, I did buy mine from amazon.co.uk, there were a few for sale,, the one I bought was supposed to be a genuine t-mobile g2 replacement (refurb I think, pressumably this just means that it was from a second hand g2 that had problems and the digi was taken out - and I'm pretty certain this is the case as mine has a thin film (which u leave on) over the back of the digi covering the tracks etc, which had a few very small air/dust bubbles under it (just noticeable when screen off), where I own a desire z, so now it sais t-mobile instead of htc, but I can live with that.
The small grey bits that you talk about were floating about or stuck on my digi when I pulled it off the main chassis. I had a look, and as far as I could work out, were possibly just for giving colour to the tiny led's that give you light to the home/search keys etc (I may be wrong on their use), but if you look closely, the tiny grey things have even smaller rectangles on them that relate to the positions of the led's on the circuit board. So I picked the remaining ones off the old digi, put them back in their correct holes and stuck the new digi in. I've had no problems (with a digi from amazon with no little grey things on it) so far, but maybee this is due to mine being a second hand original part..
Edit : Now after reading your post again, you're talking about bits that are actually on the digi itself, not the white caps that I'm talking about! Whoops. I didn't notice any grey spots on the digi itself, but I guess I must have them..

i just replaced mine with this one:
http://www.ebay.de/itm/230685692541?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
actually it says HTC on it and looks a lil bit differently than on the picture.
never the less, i replaced it really carefully and checked every connecting.
But somehow the Touchscreen doesn't work at all.
Can anyone help me ? what could be the problem ?
Wrong digitzer ?
is it okay, that the digitizer has direct contact to the frame where it is glued to ?

Hi!
I have the same problem, I have asked it already here
So you had invisible finger press in the screen, and the screen was bad responsive?
...Just to make sure my problem is digitizer problem! The service wont change it in warranty unless the problem is there all the time! But its driving me crazy! why is it happening randomly, why isnt it all the time? How could i make the screen to do this problem when i'm at the service?

Screen problem

Hi everybody I have a question regarding a screen problem I have.
Like I mentioned in an earlier post I accidentally spilt a lot of pure alcohol(the kind you use to disinfect a wound or something) on my HOX.
After a while the phone screen showed some strange grey shape on the lower right part of the screen and a bright white long shape looking like water jumping from a fountain on the left side starting from the bottom of the screen extending to almost the middle of the screen.After turning it off for 8-10 hours they grey shape dissapeared and the white remains and it doesnt look like it will ever go.
Strangely enough the HOX has no problem everything is working but I noticed that some apps are working somehow over the white shape covering it and some others like facebook seem to be under it making it visible.
I made some screen shots to show you the problem but stangely enough this white shape is not shown at all in the screen shots!!!!
Can anyone tell me where this thing might be?
LCD? Digitizer? elsewhere?
HTC funny enough suggested a factory reset to solve this and if that doesnt work(like there is a chance that it will...) to just send it to service.
I plan to play dumb to service hopping to fix this under my warranty as the phone has absolutely no scratch or anything anywhere as I never even dropped it once.
Do you think they can somehow find out what happened of maybe they will fix it under warranty?
Thanks a lot for your time reading this and I d love to have your opinions
Any photo?
Perhaps some alcohol got stuck between the lcd and glass...

Looks like overheating damage by a component beneath the screen, possibly something reacting to/affected by the alcohol.

When you say beneath the screen do you mean beneath the LCD as well or just beneath the glass?
I am just thinking that if its beneath the LCD it would probably not show plus the phone would have some kind of functional problem(it works just fine) wouldnt it?
Beneath the screen assembly. It looks like (possibly) some component or board has caused damage to or affected the digitizer, as your actual display seems ok.

So the service corrective action will be a screen assembly replacement or you think that something more will be needed?
Also if the digitizer was damaged wouldnt the phone use be affected?Cause the device has not been affected in anyway.
Everything works like it used to before this damage.
Send it of for repair, youll have to pay of course, how much tdo you like your phone?, that's the question.

I like my HOX very much otherwise why would I pay 428 euro to buy it?
Of course what makes the HOX stand out of the samrtphone crowd is the amazing display so of course I want it fixed.
I will try to cheat saying I know nothing about it(the phone doesnt even has a scratch) hoping waranty to cover this but if this doesnt work I ll have to pay 196 euro for screen replacement.
Although appart from that mark nothing else is affected I am worried that perhaps a screen replacement might not be enough if the digitizer is affected by something beneath it.
Do you think that a screen replacement will be enough to solve this problem?
HTC will give you the digitizer and LCD, especially if you end up paying, which will then get you a new bezel and unibody all still tapped up in protective coat, I've had it done for my phone, 160gbp.I even think you get the Onex+ version screen, gorilla glass 2.Could be wrong

[Q] Touch screen madness

In the past month or so my Dinc2's touch screen has become increasingly erratic. I don't think it's the screen itself, because anytime problems arise, a quick off and on of the display will fix things. However, the problems seem to be centered on the bottom section of the screen...weird.
The problems I'm talking about are unregistered presses, pressing one place and something happening in another place, presses happening without any contact at all, etc. For example, sometimes I won't be able to drag to unlock, but when I turn the screen off and on, it'll work.
I'm thinking (hoping) it's a software thing. I'm running CyanogenMod-7.2.0-vivow. Are there updates to this ROM? Should I just try another ROM?
Looks to me like a faulty digitiser. But try wiping and refalshing. It won't hurt. Good luck.

After wiping, should I flash a fresh version of the ROM or restore a backup?

try wiping and flashing without restoring. start fresh. if it works, then you can look int restoring.

Didn't work. Any other ideas? Not sure what this digitiser thing that you're talking about is...
EDIT: Ahh...it's hardware. Well, crap. Is there a cheap way out of this mess?
I found an "HTC Droid Incredible 2 Tough Screen Digitizer Replacement." $24.99. Is this the solution?
If you truly believe it's the digitizer, then yes, that's the way to go. I warn you though, the digitizer is glued to the LCD so you need patience, a light hand, and a blow dryer with low heat setting. I replaced one myself and managed to make a small spot on the LCD where I must have accidentally flexed it a little.
Back on topic, I believe I'm having the same issue with an Original Incredible. I turned on a developer option that registers screen presses as dots on the screen and I have two, almost constant, finger presses in the upper left middle of my screen. I'm thinking it's the digitizer, solely because the presses also occur in my TWRP recovery. Lucky for me, the digitizer is only attached to the front housing of the Incredible, so I just have to purchase a whole new front housing with digitizer attached. Best of luck on replacing the digitizer if you go that route, but you may as well want to invest in the whole screen + digitizer package if you can afford to.

Screen not showing image

I've recently ran into an issue where the screen on my dz does not show anything on it. The phone works and responds to touch however it does not show anything on the screen apart from a couple of white lined down the right side. Would this be a screen fault or a connector fault with the ribbon?
|Sent from the bowels of my crypt|
It could be either the main flex cable or the LCD, unfortunately there isn't a good way of testing other than replacing pieces to see what cause this. In truth your situation seems to be 50/50 caused by main flex or LCD, but I still am leaning toward replacing the LCD if you don't want to buy both
