Hey people!
Ive recently put the weight of a couch on the screen of my phone. My screen was already cracked from a previous drop but everything looked fine still.
After putting that much weight on my screen, half my screen is permanently black unless I put pressure near the bottom of my phone. It somehow releases the blackness temporarily.
My question is [Q] do I need to replace just the screen or did I screw up something else as well?
TIA
I have the same problem with my screen now. To fix it you need a new LCD. The cracked up front part is called the digitizer and you might as well replace them both together now. Only problem is to find out if you have a wide or slim LCD connecter cable and there's no way to tell until your phone is disassembled. Good luck!

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?
i think i'm screwed. so i previosly dropped it and it got a few cracks in the top right corner only one of which dipped down onto my viewing area. functionality was not affected. really as good as you can hope for as far as cracked screens go.
dropped it again and didnt hurt the glass any more, but the screen is now black. phone is on, buttons light up, i can even USE THE SCREEN, i just cant SEE anything. i can answer calls by knowing where to swype my finger and end them by pressing where the end button is. for a brief moment the very very bottom edge had a thin stip of green-pixely-ur-fcked-dude at the bottom.
So my question is what broke??? I dont really think the previous cracks are relevant but just in case...
Things i have done: restarted the phone by holding power button. removed/reinstalled battery, unplugged/replugged screen inside phone, whapped phone a few times, squeezed phone gently in various areas, searched forums until bleary eyed, browsed internet for phone cases, browsed internet for pictures of cats, posted this thread.
the extent of my knowledge is that the screen is composed of glass on top of the digitizer on top of the AMOLED (aka the LCD?). and before i realized i could still use the screen i was praying i was super lucky and maybe the screen came unplugged. but not so.
any advice? i previously saw that replacement glass is cheap but read that the whole setup is expensive. i do not have insurance on the phone. i do intend to fix it myself.
Most likely the screen needs to be replaced now. Theres a how to on this. Ebay sells replacements.

You need a flip phone.
Definitely your LCD broke. You can buy both LCD and digitizer on eBay for about a hundred bucks I think. Its not hard to do it yourself.

For future reference did you at least have a case on it when it dropped?
Sent from my SGH-T999 using xda app-developers app
No I didn't have a case on it. probly wouldnt have saved my glass given the way it landed on gravel (8 inches off the ground btw). Mighta reduced the shock that caused this problem tho.
Well I woulndnt have guessed that LCDs usually break this way. I woulda figured if I cracked the LCD or something (under the glass) that I
would just end up with a mess of colors or something. I wonder what went wrong...
So my new digitizer and LCD will come together? will I have to buy new glass seperate?
Is it possible to pilfer to digitizer/LCD from a used phone with cracked glass? Probly not huh, cuz the videos seem to show them getting destroyed upon removal.
Thanks for the info guys.
Is there any physical damage to the phone you can see? If not, pm me as I may have an idea.

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.

Thanks for the info! Is it relatively easy to turn on the option that shows screen presses?

so the other day i redid my front lens(the glass) again and the first day it worked fine, the second day however, theres an issue with the screen coming on. i think theres a loose connection somewhere but idk if its on the mobo or the lcd assembly, anyone have a soulution? yes i am comfortanle with taking the device apart and working on it
I'm having a similar issue. The digitizer is unresponsive and the keys at the bottom will not work either, all after installing new glass. I did some digging and found that the LOCA glue that is utilized may be an issue. So I am going to disassemble, clean, test without glass, and then reassemble should things be working again utilizing a different brand of LOCA that I have already in stock. ****Credit for this response goes to am iFixIt post***** Best of luck, let me know what works for you, and I'll try to remember to do likewise. P.S. I have a Note 2 that has the same problem using the same batch of glue! Coincidence?!
