s4 half alive - Galaxy S 4 Q&A, Help & Troubleshooting

so im trying to figure out whats wrong any suggestions would help ill add pics in the pics i add thats all i get as far as what state the phone is in black screen just a vibrate when i turn on the phone and a few lights thats it. OK the pics won't upload but like I said when I start up phone it vibrates and notification light fades in and out like its starting up now that little blue light stays blinking so I know its on and the soft keys are responsive just a black screen nothing else works

Tried battery pull is it charged ?
I would still go through with trying to get it into recovery mode even though you say screen is off.

so i tryed to pull battery and tryed recovery mode no sign of any lights at all on screen screen stays dark all phone shows is soft key lights and the little light blue light that blinks on the top when phone is on and every time i go to touch the phone it vibrates as well

Is the phone rooted ?
If not try connecting to a pc and run kies to see if it reboots that way.
If it is rooted try to reflash thru odin.

i dont know if the phone is rooted or not like i said i cant see anything to determine that can i be having a lcd digitizer issue?? i tryed running with kies and it doesnt connect my pc picks up the phone though not a problem i can go into the files on the phone but there isnt much inside the phone eithier

How long have you had the phone under 2 years still under warranty.

i didnt buy the phone nor do i know who did so i wouldnt know and in addition the screen is cracked so i dont know if they would even cover that by any chance do you know where i may get a cheap lcd digitizer ?

That was my point..
It must be broken or the digitizer connections must be loose..
You said it..its broken
Check ebay or somewhere..you'll find plenty..
Press Thanks if I helped

[Q] Status LED ?

I tried looking in the forum for any info on the status LED next to the speaker on the front side but I don't see any posts on this. Is this LED supposed to flash or do something? On my HD it has never worked? Is it supposed to work?
I remember on my Artemis it would flash green for good reception, blue for bluetooth and red if the battery was low.

I may be wrong but i was under the impresion that this was a sensor rather than a LED.
No, that's entirely correct, it is the light sensor. The LED is in the power button.
the status led is on the power button on the top right hand side of the blackstone...the place u highlighted is a sensor as what scotia has point out..
I think that it is a proximity sensor used to blank screen when you put the phone on your ear to talk.
It's actually the light sensor used for when you have automatic display brightness enabled. When it's dark, it turns down the brightness... And when it's a sunny day it cracks it up. I am not sure whether it's used to blank the screen during a call... This seems to happen after a period of time has elapsed.

ok thanks for the info.
So does the power LED on the top side flash any color to show the status of the reception or does it only light up orange when it charges?
Thanks.
doesn't do anything for reception..although mine flashes green hen I have a message/email/reminder
pity though, a decent LED to show such things was probably high on everyone's wishlist
No, the HD is perfectly unobtrusive. On my last PDA the LED had to be tweaked to stop flashing.
Too bad this isnt a LED diode Since I got on my Diamond a light notification (on the bottom of device)... when I recieved new sms... now on HD there is no way I can figure do I have new sms or notification unless I turn the screen on. The only hardware flaw by mine opinion
When its lying down, I agree with you. Then I have to turn on the screen. However when its lying next to me I'm usually not in a place were I can't use my phone, so the sound is on anyway.
I actually think its quite good the LED is on the top, it's easelly visible when the phone is in my pocket. I just have to pull the phone up a little and look down to see the LED (no need to get it out and turn the screen on). I like it on the top, nice and discreet, and not anoying me when I'm looking at the device while using it.
Perhaps a combination would be nice? Front and top That would sattisfy most people I guess...

Bricked Trinity?

HI all,
i have an SFR300+ also called Trinity. I never customize him or anything. Since this morning when i turn him on , the green led turn on and turn off but the screen is black with light on(retrolight? in french retroeclairage). if i turn him on and clicking some button it appears the "very nice colored logo SFR" but he is blocked here. when i turn him on as bootloader mode, he turn on but always with black screen and light on.
i don't think it is the screen cause i saw it ok.
when i try a hard reset i saw options, i make it and he's trying to reboot but black screen and light.
i try unbrick with splxploit but it doesn't work. and with -c 1 and 2 and 3.
I hope there are some way to my pda
Sorry for my so bad writing, i try to do the best.
Thank for your help!
Edit [ maybe can help, when i'm on bootloader mode i know it's ok because i can use unbrick, and it's recognize the phone and saw SPL number etc... ]
UP
No one?
i've resolved my problem, it's an hardware problem. the left bottom connector is tired.
so thank you all!
I have nearly same problem ... but when my trinity runs any "complex" process it just have scrambled sreen and soft reset. Then black screen with light. And when i want to turn trinity on ... it always have black screen with light but sometimes it just normally turn on. And what is that left bottom connector ? You meant HTC-Ext ( Mini USB ) ?

they are on by default over here..i haven't used android long enough to change the setting if it even has one so mine has to be default. I have my brightness set to auto but im pretty sure that was default also.

me neither :/
Mine also automatically lights up when I hit the power button. I have not done the OTA.
That's SO weird. After reading the title of this thread, a few seconds later, my lights stopped coming on, too.
Turned it off, pulled the battery, and now it works fine.
ya mine just randomly started working with no reboot ahah..how weird..now to get my ota >/ still havent got it yet
I just came in here to find this thread (how do you search in the XDA app??) because I am using my phone in the dark for the first time (hotel, trying not to wake my girlfriend) and my buttons weren't lighting up.
I did a quick Google search and found they won't light up if you turn the screen on when the phone is plugged in, and this is apparently by design.
For some reason mine never work in the morning in the dark (when I actually need them to), but they always work during the day. I figure there is just some bug with the light detector.
For those having issues with the lights not turning on, are you plugged into a USB cable? Mine do not turn in when a USB cable is plugged in, but they do otherwise.
Mine never turn on at all. They haven't since I got the phone. At first I thought it was by design then I realized how stupid that would be and looked it up. Sure enough here is the thread with people having the same problem...I'm on hold with HTC as we speak...
Capacitive Touch Buttons won't Illuminate
I found this thread in a Google Search and wanted to bump it:
I just picked up my white EVO today. I just noticed my capacitive touch buttons don't light up, though they do function. This makes the phone impossible to use in the dark. I was going to ask if this was a setting I was missing, but after reading this thread it seems like a small bug. Have anyone found out what the status is on a fix? thanks!
Ok guys I discovered that the button lights have a light sensor, this sensor is located under the earpiece speaker on the left side looking at the phone. If you have it plugged in you can cover the sensor up with your thumb and the lights will turn on. The lights also will not come if you are outside or in a well lit room. I hope this helps, and still dont know what to tell the OP as his happened in the dark.

black spots on screen right when the phone is almost shut down...

I just noticed it today, when i woke up... Turned my phone on and off... And just when the samsung logo is gone, and the screen is not completely black and the back and menu button are still on. I could then see black dots on the screen, i tought it was something on top of it, but couldn't wipe it off...
I put it onder a light and saw nothing... very strange... What could this be??
I tried it again and again, and it was always the same...
Can someone try this in a dark room? to see if you have it too.
Could it be influencing my screen? I don't think i see it when my screen is turned on.
Thnx
I have seen those on 2 SGS2's.

Ah ok...Nothing to worry abouth than? you saw one without it too? It's only the 5 seconds when the phone is in this not complete black when the back and menu button are still on before shutting down completely.
But I don't know if this influences my screen or if it's just normal. What could it be?
Hey i've got an sgs2 with this similar problem of black spots on random part of the screen when i shut down my phone. it can be seen before the phone vibrates off. Is urs fixedd?? or sent for replacment??

How to check if defy with broken screen is still working?

After a drop my defy has the screen gone. Digitizer is completely shattered, and also the LCD stays completely black. Is there av way to check if the phone is still working? If I try to power it on the led became green for a few seconds, then blue, then it's turned off and nothing else happens.

Try to connect via adb, or check if the Android screen cast shows you the content of screen!
It does not even show up on window device manager
