hi
my galaxy s4 gti9505 got water damaged
i opened it and cleaned it the propper way
now then first phone would not charge and after more drying and cleaning finally got to work.
the problems are as listed below
-touch screen sometimes starts responding on its own without me even touching it but after pressing power button and turning screen back on starts to work again
-will not connect to computer did before but now has stopped keeps saying connected to dock but charges
-touch screen above the home button and menu button and back button about 1 cm of the screen does not record my touch for eg. if i type in a keyboard holding phone vertically i cannot use the space or symbol or even keyboard setting (however when phone starts responding itself them buttons start working by themselves but will not allow me to use them sometimes i can use space).
ok now what i have done so far is as follows
- was rooted so my knox counter is 0x1
-warranty has been voided because of water damage and knox counter and i also spoke to samsung and they said we will charge you for fixing it but not sure what the problem is
-its on android 4.4.2 stock now but no propper bootlader as it was on chainfires root
-i cleared cache and full factory reset several times
i changed my charging port unit but made it worse as i could not lock screen using power button kept waking up strait away so i changed back to my first charging port flex cable and that issue has been sorted.
im using the phone everyday and touchscreen works fine apart from that little problem so im thinking the digitizer is ok
i think it is the function button or sensor that is causing this problem i am having
need your help guys

Noob here, I've searched but no joy on this one...
My Touch HD has just developed a foult where the screen is dead. Nothing happens when I switch it on but the device works...when I connect it to my PC it syncs happily and it rings in.
Which suggests it's hardware...EXECPT
I CAN get the screen to switch on by forcing a power down (hold the power button until the warning appears), if I then cancel this, the screen functions quite happily and will even go in and out of standby until it switches off...
I have tried a Hard Reset (Clear Storage method) but it is still the same.
If I try and flash the ROM, it switches the phone off and the programme fails.
It does occasionally pop up with a Microp error but not every time...
Help, please?
TIA
I developed a similar error today. The phone has worked just fine before.
The screen operates just fine while it's lit up, and when booting it works without a problem. However, if I turn off the screen or if it turns itself off, I can hardly get it on again. The power button itself works just fine since I can use the device blindly while the screen is off (but should be on). So I could launch programs blindly by tapping the screen accordingly. To clarify, the two states are:
1. Screen sleep | Screen is off | Device doesn't respond to touch
Push power button
2. Screen awake | Screen is off(!) | Device responds to touch
What the hell is that all about? In order to get the screen lit up when I wake it up, I need to push the power button perhaps 10 times before the screen actually lits up.
Any ideas?
same problem here

i had this after 9 months and it needed repaiired under warranty. replaced the motherboard i believe.
I tried to flash the original stock ROM. No help, so off to repair it is.
An update
The repair service needed to change:
Mainboard
Flexible PCB
Display
Now everything is working just fine.
Hi i have problem with my s5 display, it starts going crazy like scrolling up constantly, when i use it and then switch the power button to shut thr display the phone does not power back up unless i remove battery, otherwise the two button lights only show.
Prior to this problem, it started when my mic at the bottom stopped working, and then the pinnacle point was when i unrooted my s5 and rebooted, immediately the colors turned to different tints of colours.
The next day it started going all fuzzy and scrolling up.
Took it to samsung but waa refused as i found out about the knox counter lol
I have my usb port dock part which im ready to replace on my mainboard. But what ia causing the funny display ? I can barely use my phone, the digitizer seems fine aa at times it works for like 5mins.
What ive tried:
Factory reset
Reroot
Phoenix rom
I have a video to show you guys.

Back in October, I took a major spill off a bike @ 45 kmph(don't ask... Lol) long story short, after the spill, my S4 started intermittently losing signal. A quick check revealed it was missing its imei # and now showed "unknown baseband". A tap on the back cover , or a couple quick power cycles would bring everything back again.
This went on for a week or so. Then it just stopped coming back. I now have no imei or baseband.
I am not sure if my problem is my Sim reader module ( SD card works just fine and I have checked Sim card in another device. Works fine.) Or if my problem is the main board.
I do not get any messages from android... Just the ? sign indicating no service.
Along with the Sim/ imei issue, the hard buttons ( power, volume, home ect.) Don't respond. If I give the phone a tap in the right place ( right around the simcard reader), or a gentle twist) they work again. Side note: when the buttons aren't responding, I can still hold the power button and force a power off but the buttons will not respond in any other way. ( touch screen still works fine.)
Im just wondering if its a faulty reader or a faulty board?
I can replace either one... Just wondering what to replace?
Any help is greatly appreciated.
Thanx in advance guys.
Quick info about device... Sry I forgot to add it to op.
I337m Telus.
Rooted, stock kitkat 4.4.2
Unlocked (tho yet to be tested with another sim)
(((Another side note... I rooted using W0lfdroid method awhile back... And was amazed when my device still states Knox counter 0x0 and device status was official. Although Knox won't work.)))
Also to be noted, service menu(*#197328640# comes up blank) ????
I recommend flashing the latest stock rom from sammobile.com to see if that solves any issues that the phone is experiencing.
If you are having a hard time getting into download mode using the buttons, try to get a USB jig.
Ok. I will attempt that. Download and recovery mode seem to work fine.
Question 1. This just happened right now my s5 is starting up and sometimes it shows the s5 startup powered by android sometimes not after that it proceeds in starting up with the usual sound effects but the problem is the screen is just plain black. Now i believe my phone is proceeding to the homescreen cause i tried to ring it and it did plus my ringtone music played. I tried pulling the battery multiple times and start the phone but still same result. I also tried the taking the battery off and pressing the power button for a minute. also tried the safe mode, but none of them worked. What do you think? is it a firmware or a hardware issue?
Question 2. Im still not sure the cause of the problem. Because of the black screen issue i I wanted to backup my files saved in the phones memory. However my phone is locked through my fingerprint and I guess because of that when I connect my phone to the pc im unable to access my files. Is there anyway I can access my files through a pc and unlock it using my phone's fingerprint alternative password?
TIA
If the initial logo sometimes won't show up, it sounds more like hardware as that is not part of the ROM
If your phone is secured by fingerprint, wait for it to boot, press the home or power key to wake it up, then swipe like normal, if it's just a faulty screen, the fingerprint swipe should still work

hey thanks alot swiping the through the black screen unlocked my phone. so do you think it is a hardware issue I assume its the LCD?
but if ever the LCD is broken , the finger scanner should also not be functional? or im wrong?
The finger scanner is a separate button (Home button)
There are two parts to the screen iirc, the digitizer (Touch) and the panel itself for displaying, could be just the panel if the digitizer is still working
You can use this to control your phone without a screen, might help

i'm experiencing the same problem again. Before I guess after 40-50 restart I was able to open my s5 with a screen, but now it happened again and the difference is that when I boot it the "Samsung s5 powered by android" rarely shows and it will proceed until the home screen with a black screen?
i have already removed the battery, charged it, changed battery, boot it in recovery and safe mode but still all i'm getting is a black screen.
Any idea how to fix this? Is this a hardware issue already

Hi kenchii17
As you didn't provide answer to @*Detection* 's suggestion for backup, here comes another:
[TOOL] Tickle My Android
To get rid of all this inconvenience, I would suggest a complete reinstall. Clear everything through Recovery and then flash a new Stock ROM via ODIN.
Nice regards.

A friend of mine lost his S4 I337m, but found it again after it had been run over by a car. I'm trying to determine if it's worth trying to replace the LCD or if there's other damage.
The LCD is just tiny shards of glass (I'm betting it was face down when run over) but while he didn't find the back cover, the mid frame is in good condition and after removing it, the boards don't have any obvious damage.
If I try to turn it on, it vibrates and the LED pulses blue. Then a bit later it does a longer vibraton and the LED flashes blue. It seems like it's powered up.
If I try to connect to Kies, it just says "connecting" forever and the LED turns red. Maybe it's prompting me to unlock the phone? There's no message from Kies to that effect though.
As I've never used this model of phone before, I have no idea what the normal behavior is. Are there any tools I can use via USB to check the "health" of the phone?
FYI, I'm pretty familiar with flashing Android phones (mainly Nexus devices) and have replaced the screen on a Nexus 5, so I'm not afraid of a challenge. I'm guessing this phone is stock, so probably have a locked bootloader and USB debugging disabled, so I'm not sure if I can expect much. Obviously without a screen I can't do much. Also, he pulled the SIM and SD card, not sure if that matters.
I'm going to try connecting using ODIN next.
I actually was in the same situation as you are about an hour ago. I was able to unlock my phone by using a USB OTG adapter to connect my keyboard to enter in the pin and unlock it. After that I was able to access my files, so i just kept taking screenshots while i navigated my phone using my keyboard - installed SideSync, accepted the permissions, and finally - was able to mirror my phone to my computer.
If your phone vibrates, and the LED works, then try testing the button three buttons when you have the phone on. the red LED light is only on when the phone is either powered off and charging, or the phone is powered on with the screen off and charging, so if tapping the power button changes between seeing the red LED and not (and a small vibration when tapping the back or window button) then that should mean it's just the lcd+digitizer
Anyway, feel free to ask me about any behavior about a working s4 with a broken screen, one more week until my replacement comes in the mail
