[Q] Touch works while screen is dead? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

My friend's phone is working BUT the screen is totally OFF (black) BUT the touching is working:silly:. The screen is always off, i see nothing at all since turn on the phone.
I flashed the stock ODIN and the same situation, the screen is always off but i hear the boot sound, the unlock sound and volume up and down sound.
I can explore my phone through PC with no problem. Kies and odin see my device with no problem.
That is mean the touch works while the screen is off. any suggestion?

Prob a bad LCD...sucks cause I believe screen replacements run close to $200

Any one have had or heard this issue before?
Will the warranty cover this specially there is a nick on the screen? (I called them and they said NO)
Is the ebay assembly screen like the stock screen in color and pixel?

Is it a hardware or a software problem?:crying::crying::crying:

Samsung should cover it under warranty assuming there is no noticeable damage. Do a live chat support, give the support agent your device info (make sure you register your device under a Samsung login account).
Tell them your LCD burned out or just won't show an image anymore. Say its not water damaged, not dropped. It just shut down and didn't turn on.
They'll give you a shipping label to ship to a repair center.

White screen - is my Wizard dead.

my first for ages.
I recently purchased a wizard which looks to be virtually brand new.
now the other day I updated it the the o2 uk latest rom as it was running a really old rom.
and it has been running perfectly, i have not looked into running any other rom or performance upgrades etc.
now I was using the device in landscape and after closing the unit my screen went bright white and my pride and joy is now not usable.
I can still acept calls, the touch screen still works but the screen is pure white.
Ive contact a few places and they all say the screen has died and needs replacing
Does this sound right.
its a £80 fix if this is right. im so gutted.
any advice is great before i pack it up and send it off.
anyone please....
Can you put it into bootloader mode? If not i would say you have a loose connection on the screen to the mainboard i had the same problem with my old phone the screen disconnected for the main board so no display! If you cant get it replaced take it apart and carefully check the connections if still doesnt work i would try another screen or buy one.
even when i reset it, it stays whits so cant see anyhting on screen,
ive had someone take it apart and re-seat the cables and still just a white screen
so im off to purchase another one in hope this is all thats gone
as your phone is booting up press and hold the camera button, is the screen still white?
cant tell now. ive sent if off for repair.
Im gutted.

I had a similar issue, the keyboard sliding in and out must have worn out the switch that detects when it is open/closed. I had had my wizard a year and the screen started flickering, i dealt with it for a while, then the scree was stuck blank white unless if i pressed on the area of the phone that had the contact.
I had to send it back and got a refurb.
sounds like thats what happened to you too. Hopefully when you get it back it will be good as new
ive sent mine for a screen replacement tho not a repair.
now im worrying that its gonna come back in the same state.
Gulp
got my wizard back after having the screen replaced.
2 days later when ever i touch the bottom of the screen with pen, finger or even breath on it.
the screen goes off and the phone locks up and dies.
I have to take battery out and restart it and it then works great till i touch the bottom again.
Sound like a dodgy screen or something else.
Seems like a flexi strip(The one conecying the display to the mother board) sometimes if the strip develops a tear or is not properly connected this issue usually happens.
the shop doing the repair have said there is the following issues
1- padding issue on the screen (either too much or not enough)
2- Problems with the main board. (something on there is failling, hardware wise)
How the hell could this be happening on a device that was working perfectly
apart from the screen had died.
have they done more damage attempting the repair... I think so .!
I had the white screen 6 months ago. Luckily still under warranty period so got it repaired. It was the flexo-cable. since the fix no problem so far despites using the phone (also in landscape mode) daily.
when i got it back after the screen was replaced my xda worked great but as stated as soon as some preasure was applied to the bottom of the screen it would just die there and then.
I would have to take the battery out and then it would power on as normal
but again if i put presure on the bottom of the screen.. bang DEAD !
so sent it back to them and they told me what I stated above !
now waiting 2wks to hear what they are gonna do about it
not a happy bunny
still nothing back from the company thats doing the repair.
i dont know why they do this.
Im now thinking of getting my Xda back, selling it either on here or ebay and purchasing a new one.
Should i quit now or wait out for the miracle that they fix it completly.
Anyone in the uk reconmend a good repair company please im pulling my hair out.

HELP> Flashed Desire Rom, now screen wont light up

I have a serious problem. I noticed a bug in the Desire alphas where sometimes when the backlight went off during a call it would not come back on when the i took the phone away from my face. It always came back on eventually.
Ok now yesterday I flash alpha 8 and it worked fine. Now all of a sudden I reboot my phone bc the battery dies and the backlight won't come on at all! I know the phone is on because the haptic feedback and cap buttons are on and if I leave it on I can tell it's getting notifications.
How am I supposed to fix this?! I can't even see anything to get into recovery! My phone is unusable.
Find out every step to do a backup in recovery... see if that works

Load into bootloader
Press power button once and wait about 20 seconds
press volume down once then hit power button once
Wait about a minute and move the trackball down slowly 3 time and press it
Scroll it down once and press it four times

Unless your screen is broken you can always boot into recovery.
Take out the battery, then put it back in.
Hold the trackball down as you power on, this will boot you into fast boot.
Select bootloader, then select recovery. and bam your in recovery and can reflash.
I can get my phone into recovery. When I adb in i can push the phone into recovery, then when i hit adb devices it shows my phone and says recovery.
the problem is the backlight is not on even when i am in recovery. i would say the screen broke, but it seemed like a software problem, because it was just slow to come back on. It still always came back on. then I left it in my car chargine and it never came on again. The phone seems to be working fine though.
Kind of off topic, but did your call screen do this before flashing to Desire at all? Did you recently install a screen protector? I had problems with the PhantomSkinz screen protector making the proximity sensor less sensitive and behaved exactly how you're describing...as soon as I took it off it started working again. I'm now using a dcmugen88 screen protector and it works great.
interesting. i have one of those bodyglove or whatever protectors. best buy glued it onto my lcd. i suppose it could have started around that time. but would the proximity sensor still be deactivating the lcd even when its booting up or in recovery?
Oh, I must have overlooked that. The screen protector wouldn't cause any issues on startup or in recovery... guess it must be the rom then.
well, figured it out.
warning to n1 users: watch that lcd screen under the glass. its not nearly as sturdy as the glass cover.
the lcd/digitizer screen under my glass got cracked and stopped working. no drop, no warning, no funny colors. htc does not cover this in the warranty no matter how good the actual phones condition is.
i almost didnt get another n1, a phone thats inherantly weak (i found dozens of similar reports over the web) is not exactly a good case for a system with no insurance, no store to walk into, and very unhelpful support. they try to be very nice, but the rep i talked to couldnt even tell me whats covered and not. he just said let us charge 500 bucks to your card and we will ship a replacement, then decide if we think you have to buy it once we get your old phone. i demanded to talk to someone who did know. his manager denied hearing about lcd screen problems... after the original rep said he and htc knew this was a common problem. google didnt even return my email when i first contacted them saying my backlight was broken.
so again, be careful and get a good case.

I guess you mean there are "stuck" or "hot" pixels.
I had same problem.
So i received a replacement from the seller.
Same here, at least with a spot, it is an irregular area with a diameter of about 3mm, it's just brighter, and it's located in the upper left quarter of the display. I only notice it when the background is white, and more evidently when backlight is higher.
Doesn't really bother me tho, and especially is not reason enough to flash back a custom rom and send the device back for warranty waiting who knows how much. Being without it scares me a little since I have nothing else that would do as a decent backup
it's a known issue
search for "blotches" and you'll find a couple of threads about it.
i've seen it on 2 HD2s. i sent the 2nd one back to HTC for warranty repair and they replaced the screen.
My HD2 has started to get these the past few months, call o2uk and they said send the phone back for repair.
I dont want it to go off for a repair as devices like this never come back the same as if it was made in the factory.
I would like a replacement, i dont care if its a refurb.
Could always lose it and claim on the phone insurance lol

i have o2 premium insurance and i have a tiny scratch/crack on the screen from where i dropped it after a car crash , i asked o2 in the shop if it was covered and was told to call up and say i dropped phone and have a small crack, and would be replaced with a brand new phone.
i think i may call and mention the drop and the small crack / scratch and now have parts of the screen that are not coloured correctly lol
I have the same problem. I contacted the online dealer and they told me they would not replace it and I had to contact HTC support. Is this right?
I had this, htc repaired it free in 5 days. Go to htc uk website and call their support line. Was painless -just needed receipt (paypal proof in my case)
Did you get a replacement handset or did they just change the screen?

[Q] [DZ] Dead Touch Screen Area - what could be the problem?

Hi!
I recently noticed that an area of my HTC Desire Z's Touch Screen is dead. It might be related to me dropping the phone accidently about 1 meter on the ground, but I didn't immediately notice the effect.
You can find a video of my symptoms here:
youtube.com/watch?v=bHB41nXtwns
(Sorry, I can't use a direct link since this is my first post here)
Which part of the phone could be defect, according to the symptoms? The digitizer? Even more? Are there maybe any workarounds I could try to get it working again?
What I tried so far is turning the phone off, removing the battery, turning it back on (no difference). Also, I tried with and without a charger connected and with and without touching the phone's body to establish a common ground level (so not the usual touch screen problems here).
Thanks in advance!
If there's a screen protector on, try removing it and see if it behaves differently.

There is no screen protector on it. The device is unmodified with regards to hardware / accesoires.
It could be a loose ribbon cable, tear down the phone and reattach the cable that goes to the screen, or call in a warranty.

I advice not to do this... first call your mobile carrier. Tell them about your issue, try to get it replace if possible. Tear downs should only be done if that's the last option you have...
Sent from my HTC Vision using XDA App
just get a replacement and dont tell them what happened
I didn't buy the phone from a carrier but from amazon.co.uk. I wanted to avoid using warranty because it's a lot of trouble (phone needs to be sent to the UK, i need to S-ON and restore the original ROM/recovery firmware first, phone will probably be away for some weeks).
As it's only a minor issue, I would try to repair it myself (I'm confident that I can do that). What I am looking for is just a hint with which I can confirm that it's just the digitizer so I don't order the wrong replacement part and have to open/close the phone several times.

I'd recommend against that, as its still under warranty. Its too easy to mess something up when you do-it-yourself, and you would void the warranty.

Internal LCD broken

Hello guys,
I've had the Samsung S7 Edge since august, have always cared for it (i.e. never dropped it, etc.) when all of a sudden, while I was playing Sky Force Reloaded and charging (with fast charge) when I closed the game and turned the screen off, and back on, it was crazy. The image would be flashing white and this flashing changed with the luminosity (when was full luminosity was fine). I also had AOD, and there were no problems there, the screen worked fine. This was until I restarted the phone (though it was a software problem). After the reboot the problem got worse, and I could notice different brightnesses on different parts of the screen, when I could stabilize the image, using full luminosity (and having the setting fixed. As soon as I clicked automatic brightness, It would go mad even with full luminosity).
Having the phone for such a short time, I went to the samsung responsible repair place in my city (there is no official samsung here), because they work with samsung and evaluate the warranty and fix if the defect is on them.
Well, they told me the screen was broken (there was not a single scratch on the outside, which means that only the internal LCD broke somehow), and told me It was misuse.
My question is... How is it possible to break the internal lcd without a fall, without a scratch on the outside and having it to work on some software settings? Because I don't trust this repair shop, or their technicians (they have several bad reviews involving screen defects... they always assume broken screen), and the screen replacement is not really cheap.
Thanks in advance.
I had a similar issue with mine. It was a pink line across the screen from top to bottom. I contacted Samsung via the Samsung+ app and they had me send the phone to them and they replaced the screen free of charge.
Hardware faults can happen at any time, no matter if you drop stuff or not.
Does your screen flash also in Download Mode? AOD display?
Anyway, your responsible repair place is a sh*thole... "misuse" lol.
If you're not rooted Samsung will give you a warranty repair, at least here they'd do it here at my local Samsung repair center.
