GT-i9505 Blank Screen Problem

Hi guys. My almost brand new Samsung Galaxy S4 has just stopped working.
I was doing homework and one of my friends text me I look at the text and lock my phone screen and that was the last time I saw my screen working properly.
I later tried to turn on the screen but I had no luck, the screen wouldn't show anything, it was just blank but surprisingly it recognised my touch and made the sound. I could unlock my phone and even turn on apps by guessing where I kept them. I could turn on music and it would work but the screen would remain completely blank.
My phone was rooted and it had the stock rom but it had a custom kernel which enabled over clocking to 2.3 ghz (Ktweakers kernel I think) but the limit was set to 1.89 so I don't that that was the cause.
When I restart my phone the screen where it says "Samsung Galaxy S4 GT-I9505", I think its called the splash screen? I'm not sure, anyways instead of it being black with white writing, its really weird and is bright white with very light white writing. This is the only time the screen actually works, and the other time it works is when you try to put it into download mode but both times the screen is bright white and everything is very light and faded. After the "GT-I9505" screen goes away the screen goes black the blue LED still flashes and you can hear the samsung boot sound and the phone boots up properly without the screen.
What could be the cause of all this? I have literally kept this phone on top of my head. I have done nothing to harm it in any way what so ever. I have never dropped it. From day one I had a thick case incase I bumped it and damaged it. Anyone else having this problem? Or am I the only one? Do you guys think I'll be able to fix this or will I have to take it back to the store?
Thank you!

U can try to go to stock recovery and try to wipe cache and see if it boots up
If u have custom recovery wipe cache / dalvik/ fix permissn and reboot
else u should download a stock firmware and flash it using odin it will work incase even after u flash a firmware and again stuck at Logo etc go to stock recovery and wipe cache and reboot

Thank you for replying! I had cwm recovery installed but I reverted back to stock mod through odin. Now I am trying to wipe cache through stock recovery but the problem is that I can't see anything that I am doing. I am relying on pictures of the stock recovery. I know that my phone goes into recovery mode but it does not show anything on the screen. I am assuming I get stuck on the part where there are lots of no's and one yes.
Would It be possible if you could post a picture of that (The screen with all the no's and the one yes) because maybe then I can wipe the cache.
And I am already downloading the stock firmware, but it is taking forever because if the extremely slow internet. But the thing is that I don't see any logos, it boots fine but it doesn't show anything on the display. But I also know that the display is working because it still shows the "GT-I9505" screen. I'll post my progress here.

Okay so I downloaded the stock rom and flashed it with odin and it basically did nothing. Rather before flashing the stock rom, the splash screen would show (the screen that says "Samsung Galaxy S4 GT-i9505") but now it does not show anything. It turns on normally like it should, it makes the boot sound but does not show anything on the screen. If you have the lights turned off, you can see a flicker when it turns on and thats the only time the screen actually lights up. What do you think I should do? I still think it might be a software issue. Also I don't think I have warranty because I have flashed my phone a few times. Its still very upsetting that this has happened because honestly I haven't done anything to this phone.

Haha no I don't think so Well I'm still taking it back to Singapore but I will probably have to pay for the repair.

Does your screen not have cracked (from the inside ) ?

I don't think it does. Because before flashing stock rom, the splash screen would show and it had no cracks. So no actual damage, I still think it is a software issue but I don't know how to fix it :/ I still can't decide if I should take it to Samsung (which will take like a few months) or I can take it to a local repair shop and they can look at it which shouldn't take more than a week.

For repairs it takes 2 weeks before you get your device back (at least in my country)

Repairing it doesn't take very long, taking it to the repair centre will take time. I bought my phone from Singapore and I have to take it there if I want to get it repaired. I took it to the Samsung repair centre in Bangladesh, they said they can't repair my model because they don't support it here :/

The samsung centre here will send it to a repair centre. Here i will lose the phone for max. 2 weeks.

same problem
The same exact thing happened to me yesterday. Opened a text from a friend, tried turning on the screen and black screen. Thinking of sending it to samsung but do you have a solution yet? Was the problem diagnosed?

My Samsung galaxy s4 i9505 screen is dead--
I woke up this morning and my phone is still charging... But I cannot see my any data in the screen.. But my phone is still working.. I can receive phone call with my headset.. I cannot see anything in my screen.. It gone black.. Can anybody help me to fix this.. Or is this a firmware issue.. My phone has been rooted and installed official android 4.3 jellybean. Please help!!!

Just today I spend the same, except that the screen starts flashing, and at times the picture and the picture looked twice was very unstable, it restarts, and for the image of the i9505 without problem.
He ruled out a physical problem as it starts each. Device failure begins after displaying the Device Model
.
The touch and other features of the device, work perfectly. Try booting in recovery mode and I could not look very bad image.
In trying to backup my data with titanium to try to do a factory reset, began to regain normalcy. And right there my device works perfectly.
Bring 7 hours working normally my device. But I have fear of failing again. And now looking for information about possible solution. No warranty now.
What do you recommend? It's failure is becoming common. My device is doomed to die without remedy? Thank you very much for your answers in advance. Use translator apologies. Speak Spanish

hello guys, i got mine i9505 lte version 4 months ago. yesterday i pull it out of my pocket i tried to wake the device up but nothing .. just black screen just like the guys before me here. so today i opened the phone and pulled out and push it back the display connector... AND VOALA WORKS AGAIN! but after 5-10 minutes and everything is again black?! wtf i said!?! its not normal! my screen is working flawlessly colors touch response... everything! do i have to reconnect the display connector every time? i think its not normal. what must cause this bug/glitch/issue?!?!

Hello Guys, this issues is very common when you rooted the device and install Wanam Xposed.
You can try flash a stock Rom and stock Kernel with odin, try to swipe cache and dalvin using ADB.
Good Luck!

GS4 touch keys are dead !!!

Hey guys,
So i bought my phone yestarday,played around with it for a while and suddenly my touch keys stopped working.I keep my touch key light on "Always Off" ..so i thought that maybe if i turn them on,it will do the trick..didn`t work,they don`t even turn on anymore.I did a restart,same thing...only that the phone started laggin` real hard (when i unlocked`it and while using the drop tray).I turned the phone off and on again,same thing..i turned the phone off,pulled the battery out,waited a couple of minutes..same thing.I eventually did a factory reset..didn`t work as well.The phone is stock,haven`t got around to rooting it so it runs on 4.2.2 with XXUAME2 build.One more thing..before i did the factory reset,i digged around the internet for a bit looking for a solution and i came across the *#2663# code...i used that and tried the Touch FW update but it only said "Factory keystring has crashed/stopped working" ..after the factory reset i tried the code again,but the Tough FW button does not appear anymore.Now,do you think it`s a software problem that can be fixed (i would like to avoid rooting since if it does not work i want to send the phone at the samsung cervice center) or it`s a hardware fail and i should just stop looking for solutions and send the phone at the service?Thanx for your time
P.S i had a GS2 so far,rooted`it myself,changed a TON of roms on it and never had a single problem...so for me GS2 > GS4 for the moment

Well, i think that to know if it's a software or a hardware problem you will have to find out by yourself.
First thing to do is to flash a new official rom : http://forum.xda-developers.com/showpost.php?p=41072377&postcount=1 (and you don't have to download the attached files in the post)
Then do a factory reset from the phone recovery (VolUp + Home + Power - navigate with the volume touch and confirm with the power button)
For the roms take a look here :
GT-I9505 : http://forum.xda-developers.com/showpost.php?p=41072426&postcount=3
GT-9500 : http://forum.xda-developers.com/showpost.php?p=41072392&postcount=2
And dont forget to search for the same rom that you have, before you flash , check it by dialing : *#1234#
And if you did all this and it haven't resolved your problem so it's Hardware, just take it to the Service center and don't worry for the warrenty because it will remind active and official even after the flash

Thanks for the info and the advice!
Though now i`m convinced that it`s a software glitch,because i just restarted my phone and the touch keys turned on (unless samsung managed to build a phone that self repairs).I`m gonna be on stand-by with that stock rom,just in case it starts acting up again.
L.E Ok,the touch buttons crashed again,so i flashed the stock firmware and they are working now.Hope they don`t die again
Thanx for the help,again

many lastKi
Well,still no luck ..the touch keys keep getting unresponsive..after a while they sprung back to life and so on
I reflashed the stock firmware a couple of time,same thing...
When i use the *#2663# code and press the Touch key FW update it gives me a "Unfortunately,FactoryKeystring has stopped" error, i should mention that on the menu it says:
- Phones`s Touch key FW version: 0x10
- Part`s Touch key FW version: 0xfa
The only app that i have on the phone is WhatApp ....sooo ..dumb question,could WhatsApp be responsible for this behavior ?
L.E i rooted the phone,intalled CWM and the Google rom for GS4 ..touch keys didn`t even buged so i`m unrooting as we speak,returning all to normal and i`ll send the phone to warranty tomorrow

It's funny you mention that, because my GS4 start to restart and shut down by itself. The first thing I did was remove WhatApp because was always gaving me errors and then pull the battery out for 1 hour, since then no more reboots or shutdowns.

I was on Wanamlite when I experienced that. But all I did was an easy reboot and when it comes back, I wipe caches xD and it comes back..
I also prefer the button lights to be off.. so it's always off from the very start

I like to keep the light off as well,but the light was not the problem,the fact that they did not respond to any touches was ).And yes,if i restarted the phone a couple of time they would come back ...for a period.Anyway,i sent the phone to samsung for warranty,see if they find the problem

Ok,i just got my phone back from warranty (it`s the second time..the first time they just resofted`it ..LOL) ..and it`s all peeachy.They changed the whole screen (i believe it`s called "digitizer" ) and that pesky problem is gone.Also ..before this i had a weird effect when i was scrolling through menu`s...like the screen was leaking or something,but now it`s gone.To anyone else that bumps into this problem (i see that the HTC One has this problem as well) ...well,there`s no way around this unless you replace your digitizer.Cheers

Freezes while opening Lock Screen

hey i have some problem with my galaxy s4 i9500, so here's the story : i've got some weird burn n reddish screen on my s4,, then i bring my s4 to the service center,, they had replace the screen for 4 times but still have that issue, then they say,, they going to replace the screen 1 more times but now with the mainboard. okay after 2weeks my s4 reddish screen fixed.
but now i have a new weird problem, everytime i try to unlock the phone ,, sometime it hangs ./ freeze,, and when i tap the power button or home button several times, it reboot itself. now im completely frustrated with my s4,, anyone have any tips to fix this lockscreen freezing? i already try to factory reset it and reinstall the firmware. anyone please help :crying:

Hi,
I believe after they changed your "mainboard" (which I'll understand is the motherboard) something went wrong, as you said you tried to factory reset and reinstall stock firmware and the problem still persists, I will recommend you taking it again to the Repair Center, try asking for another S4, I think it'll solve all your problems , when my Kindle had a battery I got a new one for free from Amazon, I guess you can try getting one S4 too from Samsung.

Bottom part of screen touch issue

Hello all,
My Samsung Galaxy Note 4 (SM-N910C) is about 18 months old, has worked fine since purchased new. It is running OS 6.0.1
All of a sudden it seems to have developed a fault whereby the bottom most part of the screen is not responding well to touch. This is the bottom part of the screen only, all else seems to work fine.
I hadn't performed any updates or OS updates and it is the default OS, non rooted.
I have tried *#2663# and pressed the 'Touch key FW update' but nothing has happened. I also ran *#0*# and on 'Touch', I can verify that the touch along the bottom part of the screen doesn't register properly.
Hasn't been dropped or anything like that, just started happening.
Is a factory default likely to help fix this? I'm reluctant to do it if it isn't going to help at all and is more a hardware fault.
I took it to Samsung and they were very unhelpful and it is now out of warranty. I just wondered if there was anything I could try before I get a new phone?
Thanks in advance.

I'd try performing a hard factory reset but clear the cache in the Recovery Menu first. As that would probably help if it is indeed a software problem.
