Screen crack :( - Xperia Z2 Tablet Q&A, Help & Troubleshooting

I've had this tablet for more than 2 years, and so far I was loving it. But today out of the blue a very thin crack appeared on the screen, no falls no nothing....
It does not mess with the image but it makes it impossible to use because it keeps registering a "touch" along the crack.. How can I tellfore sire if the problem is just the glass or also on the LCD?
Thanks for any help given

[Q] unresponsive touch screen after falling

Hello,
My phone has fallen today from my hand, and ever since the touch screen is unresponsive. It fell on the back, no visible damage to the screen. until then I had no problems with it so I doubt this is a digitizer problem. The phone had a hard case (always falling apart when I drop it) and a screen protector. All of my hard keys are working, but the soft ones (at the bottom of the screen) are not.
When I press "power", the menu seems to be stuck on the sound/silent options,with no ability to go to recovery, for example.
I tried removing the screen protector and playing with the battery but nothing is changing.
I am studying abroad now so I have no extra money to buy a new phone or any knowledge of a proper place to check my phone. A lab I contacted offered me a new touch screen for 200 pounds and wouldn't offer anything else.
I am lost, please help me.

Broken glass

Hello,
I've recently dropped my galaxy and broke the glass. I think that I didnt broke lcd sinice it response on touch. However there is an "rainbow stain" that keeps spreading. Ive attached image od that stain. I would be pleased if anyone could explain me what happened to the screen.
Thanks in advanced.
You need a new screen assembly.

Is my screen broken?

These past few days, I've been noticing unresponsiveness to touch in a certain part of my screen. This screenshot shows what I mean. I never lifted my finger while drawing, and I swiped up and down continuously. The middle band of unmarked screen seems to be failing and only works when pressed harder. Am I going to have to get it repaired? I'm tempted to use this as an excuse to jump to the G4 when it comes out but I'd rather get this fixed if there's any way I can do it

I recently broke my screen glass and digitizer. I had a region that was vertically oriented that didn't work over the rest of the screen. It is possible that the digitizer or maybe connections to the digitizer are broken. I ended up buying a new screen, as it comes with the digitizer and glass. Reading about it sounded like a huge pain to even think about just replacing the digitizer and glass. The new screen was around $70-80 on Amazon. Process was well documented on iFixit and youtube. The only problem I had was that I didn't receive my order of adhesive tape and didn't want to wait. Now I have a 1 inch area that leaks light. I can live with it until I decide it is worth cracking open again to properly seal it up.

White Shiny Stain On The Screen

I don't know why this happened. I'm using the tempered glass screen cover. Can anyone say what it this and what should I do?

Run some of the extra tools in AnTuTu to check if it's an actual screen problem.
Might be a "bubble" under the screen protector - can you "move" it with your finger when applying pressure?
Is it a spot where the screen is brighter? If so, I think it's a defect related to the backlight. I bought a cheap replacement screen for my Nexus 5 when I broke my original one and over time it's developed more and more bright areas. I suspect something is delaminating causing uneven backlighting. I believe it can also happen due to water/liquid damage, but in my case phone phone did not get wet.
Actually, I just tried twisting my phone and also applying pressure to the screen and noticed the LCD reacts (flashes) in those areas when I press hard, so I think it may be an issue with the LCD panel itself, not the backlight. In any case, I doubt there's much you can do about it, and be warned it could get worse (I used to have a spot or two near the bottom of my screen, but now I have them all over the screen.) In my case I've just learned to live with it, telling myself having paid $35 for a screen which developed this problem is a lot better than living with a cracked screen, and I'll have a new phone soon, but I would not expect this problem with a new phone.

Replace the screen or just get a new device?

There is a thin crack in the glass that runs across the screen, also it went bad long time ago. Heavy burn in and lot of pink color. Rest of the phone works fine, but I assume replacing this screen is pretty much gonna be a price of a used phone and from what I've seen doing it myself would be a no go since this is somehow glued together...
