Why do some touch screens work with cracked glass whilst others don't?
For example, recent Sony phones seem to be notorious for having screens that become completely non functional once the glass is cracked.
I have a cracked HTC, IPhone and Samsung. The touch/screen on these all work perfectly fine even though the glass is completely shattered.
Why is this? Is it poorer quality components or something got to do with how the screen assembly is put together? I thought all phones with 'ogs' displays have glass -> digitizer -> screen so don't see how this could be possible. Anyone know the answer? I think having a phone which becomes completely nonfunctional once cracked is a big downside.

Most probably, if you slip your phone, there are 2 possibilties:
1. Only the screen glass breaks and digitizer is safe (Broken screen doesn't mean touch won't work).
2. The bump caused on screen damages both screen and Digitizer too, which causes touch feedback not to work.
There are certain rare phones in which digitizer and glass screen are just a single component. Maybe just a drop of those phones could damage the whole screen+touch interface

I wouldn't call them rare. I know all new sony phones are like this If you search for 'cracked z3' or 'cracked z2' all will say touch not working. I'm sure there is many others too, Xiaomi mi3 and nexus 4 are others I can think of. I wonder if this is done on purpose so people will have to pay the extortionate repair costs? Many people would be okay using a phone with a small crack on its screen, especially if they've had it a while. But if the touch isn't working it is as useless as a brick.
It's a pretty big downside I think. I know someone who has been using a cracked iphone 4s for 2 years and has been re-cracked several times and its still fully functional.

I lost my sgs4g recently and was looking into getting an htc sensation. One thing I'm noticing is that the screens crack pretty easily (falling from 5ft). The sgs4g has gorilla glass and I would drop it plenty of times and although it would fall apart without the case(back cover and battery pops out), the screen would never crack. From what i have seen, the htc has gorilla glass yet it cracks so easily. Why is this? Is there a screen defect with the phone? From what I've seen so far, the phone seems great but the screen issue users seem to be having concerns me.

i know of a digitizer issue but an easily crackable screen? never heard that one before
ok i read a bit further and the way most people spoke of the phone,it had me think they were one and the same. the digitizer will crack easily but the screen itself will be fine am i correct on that?
Is there anyone else that would like to chime in on this? I remember reading a thread where a person asked whether if the replacement digitizer would be gorilla glass which had me think that the digitizer and screen are one and the same. Also are there any other issues with the phone besides the digitizer that i should know about?

the display and the digitizer screen are separate pieces
the digitizer is a part of the gorilla glass screen and the display is beneath that
it doesnt crack, it shorts out and stops working properly for some. it can easily be prevented. if it happens, its an easy fix and if you want a new one you can replace it i think its about 20 bucks
oh ok great how can i prevent it? and is the easy way to fix it the software update as mentioned in a stickied thread? i basically dont want it to ever look like this http://forum.xda-developers.com/showthread.php?t=1142379
All you need to do is to be a little bit carefull whit your phone ..
I wonder why are you so worried lol do you drop your phones alot ?
Sent From My Sexy Sensation.
The Sensation is a quite durable phone... I've dropped it a couple of times with no issues...

The Sensation does NOT have gorillaglass.
You can effortlessly push down hard enough on the digitizer to get it to touch the actual LCD panel underneath. It's an oleophobic plastic.

Which brought me to another question. Is it possible that certain phones have lower quality gorilla glass screens than others?

i would say yes
just from the design of our screen (curved around the edges) it could possibly make it a tiny bit weaker
Hello guys,
I've been using DHD for quite a long time and I never experienced any problems with this phone until I noticed the digitizer is cracked. I just took the phone out of my pocket and realised that it doesn't react when I touch the screen - there is a small crack in the corner. I think this is just the digitizer because the image is displayed correctly and there are also no scratches on Gorilla Glass (i also used screen protector). I have not dropped the phone recently (neither hit it with a hammer) and I'm wondering if it is possible that the digitizer has a factory defect and what about the warranty in such a case because when I heard what is the cost of repair...
Any clues guys? This is very important...
I had a similar problem with my screen.
The upper part of my screen was devastated with pieces of glass coming out regularly.Yet,the touchscreen worked.
Your case is pretty weird.I think you should take it to HTC and try to persuade them that its a defect if you're sure you haven't damaged it!
GoodLuck :good:
Hi All
Recently i got careless and i accidentally cracked my nexus 5 screen after dropping it on the ground
Currently the touch screen works but there is a problem. I am unable to answer calls as the screen goes black and does not turn on again until the person has hung up or until i reset the phone. Also when i try to call out the screen turns black as well and exhibits the same symptoms as listed above.
From people who have had experience with cracked Nexus 5 screens, do you think replacing the digitizer + lcd will fix this issue or did i screw up something big
Thanks
It sounds like the cracked glass is affecting the proximity sensor. Replacing the screen /digitizer should fix the problem. Replace the whole thing including the bezel.
Any chance you could explain why the bezel also needs to be replaced as well?
It's easier to use the screens that come with the housing, you just switch internals and pop the back on. As for oem replacement screens with housings, I've read mixed reviews. Some say theirs is perfect. Others complain of different textures on the housing, or missing ear speaker mesh. Some say their replacements have massive light bleed. If it were my phone I'd pay the extra 25 to 50 bucks and send it to lg for repair. They charge 150 dollars. Then you are guaranteed to have it be perfect again. Plus their work and parts are warrantied. Play it safe and send it to lg imo.
Edit: Also if you did break anything else they will fix that as well.
hi guys ive noticed that when typing on the display without much pressure i get a rainbow affect only for the time im applying pressure just wondering does anyone else have this problem or am i developing a hardware problem
its a bit like applying pressure on my laptop display with not much force
Are you using a screen protector? If you are, is it possible the protector is not sitting right against the screen?
I have had two idol 3 phones and I didn't notice any rainbow affect on either phone.

ya i had a glass one installed removed it and still the same so thinking it maybe faulty
I used both phones with a glass protector and not problems with or without the protector.
Sounds like the top glass is not fully bonded to the lcd.

didnt notice it when i got it new so think its a newish fault lol do you think its worth trying to get a repair or will it not really cause any future problems
I would get it checked out asap. Who knows, it may be a sign of future problems.
Looks like screen problem
Hi, I have recently dropped my S7 and my screen broke, but it’s only smal black dot on side of amoled and one line trough glass. My biggest problem is that lower part of screen digitizer stoped working. I’ve searched all over ebay for new screen assembly with amoled and digitizer but it’s expensive ~170$. So I was thinking, can I replace only digitizer, they cost about 30-50$? I’m not sure because every video on YouTube that replaced only digitizer had fully working amoled. Do you guys have any experience? Any advice is appreciated
Hello,
As seen on some drop test videos, sometimes screen can be totally messed up but digitizer can still be working good. So my guess is that they work independently and so a new digitizer could work good even if the screen as some dead areas or lines etc...
But due to the fact that Samsung glue the glass with the digitizer and with the screen panel, it's a very difficult process to just remove the glass without scratching or breaking the Amoled panel. Better be well prepared to it, have the right tools and have a lot of dexterity and patience. It's already a big pain to separate the screen for the glass, so if you're planning to separate and replace only the digitizer, then good luck :-/
Before trying this, you still should call some repair centers to see how much it would cost for a screen replacement, but unfortunately it is most likely to be expensive. Also, be aware that buying yourself a screen replacement doesn't guarantee you that it will be an Amoled. A year ago, my brother broke his OnePlus 3 screen, and it was almost impossible to find an Amoled screen replacement, their description was saying Amoled, but by reading well, we could always find somewhere "TFT" or "LCD" which are not Amoled.
In the end, you have to be aware than any flagship phone cost an arm to repair, especially the screen as everything is glued and made for you not to be able to repair it yourself. So it is very highly recommended to protect your phone with cases and screen protectors (plastic screen protectors protect the screen better from shocks than glass screen protectors, even if plastic feels cheaper). Unless you have a lot of money and can easily pay a repair, protect your phone!
Sorry, that's all I can do for you...
