Galaxy S5 :: Why Don't Have A Backlight Upon Boot
Mar 1, 2015
I've had my SGS5 for a month now - great phone.
But suddenly today the backlight went out, i pulled the battery, waited a couple of minutes, reinserted it and turned the phone back on.
I can barely see the Samsung logo, it looks like the screen is set to 1% brightness (as close to complete dark as it will go). I hear the boot sound, but it's just to dark/black to do anything from here.
Is my device faulty? I cant enter recovery mode because it's nearly pitch black.

To conserve battery should this be checked? I've heard that if you check the box it runs your battery down quicker.

My sister has an S5 and got it wet. She thought it was dead but turns out the backlight only works now when it is turned all the way up. The issue with thar is that max brightness drains the battery quite well. Any way of fixing the backlight? I tried Lux auto brightness and that just turned the brightness down, which made the light turn off as it does when adjusted manually.

I got an S6 Edge Gold phone last week and noticed a weird duplication of backlight reflections of the capacitive keys.
There is an original light, and then there are two more reflections which is very weird. I can tell they are reflections because as I tilt the phone those two reflections change angles while the original light stays in its spot.
The issue is also with the notification color lights. When ever it blinks I see two reflections (one above and one below). So it looks like a grain of rice instead of a small circle.
Please see the image below for a better understanding:
My inspection of the device tells me that theres something wrong when the different layers of glasses were stacked. I have looked at some other Edge phones and they don't have this issue.
I have also seen that when very bright light shines in all angles and when the phone is tilted (with screen turned off) and observed carefully I see diagonal lines on the entire screen with a space of about 5mm each. It is very hard to see them, and when I turn the screen on I can't see any flaw.

I'm having serious problems with my S6. The phone crashes, shuts down and reboots over and over again. Right now thee is no way I can boot the phone without freezing. Even in safe mode and recovery mode the phone freezes.
I had these problems before and returned the phone. They 'flashed' the firmware and checked all the harware (no problems). The phone worked properly for two weeks but then all of a sudden the problems were back.
I want to make backups before I return the phone again but that's simply not possible. If that's not possible I prefer erasing everything somehow, without making any backups. I still have my backups from a couple of weeks ago.

I have galaxy s6 G920F and I can't return to stock ROM, if I flash via Odin android 5.1.1, it says successful then stops on boot screen. I also did factory rest after installing also cleared cache but nothing happens. I tried France stock ROM 5.1.1 XEF I guess also UK BTE but I got same results.. but I can install custom ROM and it works fine but I need to return my phone but can't until it's on stock ROM.
It also says dm-verity verification failed. I just need to boot with stock ROM other error or warning messages don't matter..

I have a galaxy s6 g920f and i recently updated it to 5.1.1 via odin wih build number bofj;I'm not liking the firmware as it cant be rooted via pingpong so i tried cf auto root but it stuck on the boot screen so is there anyway to root it? Or can I downgrade to 5.0.2 back and i have seen some guys who reset the knox counter (which is shown in the bootloader) so I have got knox 01 (00500) is there anyway I can get it back to zero?

I just bought a S6 to use Samsung Pay.
Received it today, fist thing I had to do was update it from 5.0.2. So I used the OTA update from t-mobile option (as it offered it as soon as I turned the phone on and connected to Wifi).
I click the "Restart and apply update" when it had finished downloading, set the phone down, browse the internet for a little and notice it was hanging on the Samsung logo.
I try to turn it off and on, nothing works. I try entering recovery mode, won't let me.So I then download and try manually flashing 5.1.1 through ODIN.
Everything says "PASS" in ODIN, it reboots and gets to the Samsung logo, shows the android robot, says "installing updates" but when the bar reaches about 45% it switches to "erasing" then goes back to getting stuck on the Samsung Logo.
What can I do ? I really don't want to trip knox as Pay is the sole reason I bought this stupid phone, all other Stock ROMS now fail odin and G920TUVU3DOI1_G920TTMB3DOI1_G920TUVU3DOI1_HOME.tar is just doing the Install then erase thing.

I have a friend's Galaxy S6 here. A password was suddenly set and nobody knew why, she really said it came out of nowhere! So she asked me to get her photos from the phone and reset it afterwards.
I did that on other phones before so I flashed TWRP and pulled the files with adb. I tried to reboot after that and was stuck at the boot screen. I tried flashing some stock firmware from stockrom.net but Odin always says FAIL!

I purchased an S6 off of CL yesterday, was able to use it all evening and set it up via Wifi (purchased it after Verizon stores were closed, so have not been able to get a SIM card or get it activated with service). Everything was working perfectly.
This morning it asked to update, I accepted. Ever since the update when booting it is stuck on the red verizon screen. I have tried clearing the cache and doing a factory reset, no changes.

I have had several occasions on turning on my AT&T Galaxy S2 phone where all 7 of my screens were blank except for the 4 icons at the bottom. In fact, every screen had a message in the middle saying to drag items to add them to the screen, like it was *supposed* to be blank. Before today, turning the phone off and on again resolved this.In fact, when I clicked on the Applications icon at the bottom, got nothing but a spinning circle. After a minute or two, I pulled the battery, returned it, and powered up again. This time, everything is again normal. But I am concerned. This phone is just 5 weeks old.

I'm using rooted 2.3.5 KI3 firmware and I've downloaded a nice .zip file boot animation that I want to use on my phone.. Firstly I tried finding the bootanimation file using ASTRO and found 3 files...
/sbin/bootanimation
/sbin/bootanimation.sh (tiny file size)
/system/bin/bootanimation
...and none of them state their file type. I understand I'd need to backup/rename the file before I replace it with bootanimation.zip ?I also tried flashing the .zip file in CWM recovery mode, but I hadn't renamed the file to bootanimation.zip and the update aborted. Would this be necessary for it to work?

I just want to preface this by saying I cannot root my phone. Not because I am incapable but because this is my corporate phone and I would no longer be able to use it for work related things if I rooted it.
I am using a Bell Canada Samsung Galaxy S6. Every person I've come across that has an S6 or newer samsung phone is able to boot up on silent and not get the samsung noise when the logo comes up. I tried doing a hard reset on my phone just to test to see if my phone would boot silently if I set it on "Mute" mode and it did WITHOUT encryption but I am forced to use encryption by my company's device management policy app or I can't access other things like my e-mail.
How to get the device to boot silently without rooting with these factors in mind? I reached out to samsung and they were clueless. As far as the support knows, the phones cannot boot without the noise even on "Mute" mode which is clearly not the case.
I've tried the Silent boot app as well with no success. I've noticed this happens only when encrypted and upon checking the volume settings on the screen where you have to put your encryption password after booting up, the volume settings are kicked back to default.

I have a G920I that I just rooted with Odin. After that I installed TWRP manager and used it to install TWRP recovery. On reboot i am stuck at the black and white powered by android screen. I can reboot the phone with the volume down and power button combo but i cannot get it to boot into download mode using volume up+home+power buttons.

I flashed the XtreStoLite Bootloader and Modem for 5.1.1. After that I flashed the new TWRP with Odin, it passed so there shouldn't be any errors.
I tried to boot into the recovery after I turned off the phone with volume + / power / home button. At first there was only a picture of an android but now it doesn't do anything when I try to press the buttons.
The Bootloader shows that the knox is already tripped so it's w/e. Tried to check for root in Android terminal but apparently it doesn't recognise the command.
How to proceed, so I can finally boot into twrp?

I have a G920F and the boot animation is not working as it should. I'm on 6.0 Beta and don't think the problem is coming from the beta because if I remember correctly, the first time I booted the beta everything went smoothly. I am not rooted and the phone is completely clean.
The problem isn't a big one, but it isn't working normally. When I boot my S6, the 'Galaxy S6' screen comes, then no boot animation is shown, a black screen is shown instead, then after the small vibration, the boot animation is then shown without the sound. (an the phone is not in silent/vibrate mode)
My guess is flashing a new stock ROM fixes the problem, but I don't have enough time to sort the settings and stuff out after flashing.

I got a Samsung S6, been good for 6-7 months now. Today it just shut off, battery was at 25-35%. I turned it on and it has since been stuck on the logo screen. I searched it up on the internet and tried doing a reboot with Volume down and Power/lock screen, but it just goes back to the logo screen and wont go past it.

My GS5 was working just fine this morning. Out of nowhere I picked up my phone and it was on a black screen with green, white, red, then white again, then grey, blue and red words. It reads as follows;
BOOT RECOVERY MODE
CHECK BOOT PARTITIONS
sbli partition doesn't exist
ODIN MODE
PRODUCT NAME: SW-G900A
CURRENT BINARY: SAMSUNG OFFICIAL
SYSTEM STATUS: CUSTOM
REACTIVATION LOCK(KK): OFF
KNOX WARRANTY VOID: 0x0
QUALCOMM SECUREBOOT: ENABLE (CSB)
RP SWREV: S1, T1, R1, A2, P1
SECURE DOWNLOAD: ENABLE
UDC START
I have tried everything from removing battery, removing SD CARD, SIM CARD, connecting to charger, connecting to USB cable on my laptop, holding volume up, home, and power button. My biggest fear is losing all my data. I have 100's of photos of my 3 month old newborn on my phone memory because I was running low on my SD CARD. I can't fathom losing all her newborn pictures.

I noticed recently there was a youtube update. I'm seeing whenever I reboot or turn on my phone that the youtube app automatically starts up. It shows on my active apps widget. But it does not physically start up in a window though. If I go to the running apps screen in the application manager, it says that youtube is running the offlinefiletransfer service.
Is there anyway to disable this?
