I think one of the main reasons for the Galaxy S4's slowish start up time is because your stuck there for 10 seconds on the splash screen. Other phones like the S5 immediately show the splash screen because they made it faster then the S4, that's why the Galaxy S4 logo gets a little bit of a cut off when you just finished holding on to the power button. It's kind of hard to explain. But I want to just make it immediate, because I know it's possible. Same with the S3, that was almost immediate getting past the splash screen.
The spash screen you're talking about is the one showing your phone model. The one after is called bootanimation.
Modifying the actual splash screen is difficult and dangerous.

I installed Euro firmware, on the second flash everything just stay'ed black, and I waited awhile till I decided to power off then power back on. First thing I saw was AT&T connect boot screen, then it went black but I can still hear Samsung's power up theme, also device has a Vertical Line running down the right side. I noticed that If I press power button twice Tab comes on, and everything looks great, so I rooted my device and installed Titanium Backup,Everything seems okay. So my question is how do I get rid of the AT&T Boot logo and to be able to see Samsung logo on boot?
\\\\\\\Exactly what happens on fresh boot/////
-fresh boot- AT&T Connected screen comes up, then screen goes black with the line on the right, then Samsung's power up theme song comes on buttons light up screen stays black line goes away, then screen still black, then to initialize the screen I press power button twice. Comes on and works fine.
****Would love to fix that part, I would be most greatfull for life! Willing to pass on info, to all who want more!****
*need help on pre-installed boot screen*

Install euro firmware with bootloaders. JJ4 is good one since it's bootloader is not signed. Then you can install newer euro firmware over it.
However, so far there is no known way to go back to AT&T bootloaders. So you ca't fully restore to AT&T if needed.

Thank you for your reply, I will think about it! Seem's I have to make a choice. But at least there is a way to fix the problem.
Thanks!!!!!!!!!!!!!!
I got a samsung vibrant Tmobile and after flashing a custom Rom
I got AT&T bootup screen! Any answer will be appreciate !
There is a thread for this titled "How to fix at&t black screen with thin white line at boot up". I know you can find it by searching - I wrote it.
This thing is a month old and I really hope I can find a way to fix it. It is rooted so I doubt I can get a replacement...
I've seen other people with screen malfunctions where it shows weird colors after booting, but mine shows nothing. The Samsung boot animation doesn't show, nor does the ATT boot logo (although the sound plays). I can still use my phone by guessing where to touch and everything works fine.
Are there apps that can (with super user access) somehow disable the screen?
Is there a way to factory reset without being able to see what is on the screen? I tried the "Volume Up + Volume Down + Home", but the screen doesn't show anything.
Finally, is there a way to reset the ATT Galaxy S4 via Kies? I haven't been able to find one.
I'm guessing this has to be hardware since the boot logo doesn't show. Surely even if an app disabled the screen, it wouldn't be running before the logo appeared.

If the boot logo doesn't show (not the boot animation, but the very first logo when you first power on and it vibrates) then it's hardware. If the screen goes out after that like at the boot animation, then it could be that you messed up or something messed up a system file. This happened to me when I didn't set the permissions on my build.prop, it gave me black screen with blue LED and simply fixing the permissions in Safestrap fixed it.

I've used the lg flash tool to go back to stock several times in the past never really had any major issues. Today something went very wrong.
After the flash the phone boots on its own. I saw the lg logo, and then android with the blue bar under him. Then instead of seeing the verizon logo come up i get all black screen and it says:
Insecure boot.ing
cause=
This is up in the left hand top corner of the screen. There is no cause its just blank.
At this point the phone justs repeats those same 3 steps above over and over until i hold the power button to turn it off.
Next problem is i can't get it to stay in download mode again to repeat the process. The phone enters download mode for a slit second and flashes a bunch of white writing up in the top left hand corner of the phone so fast i cant read it and then the screen goes black.
Anyone seen any of this before?
I'm lost at this point...
So I have an Galaxy S4.
Whenever I try to turn it one a couple of things can happen\
1. It goes past the boot screen and boots successful only for the screen to instantly go black. The blue led stays on.
2. It gets stuck on the Samsung Galaxy S4 screen
3. It displays a weird pattern

Does anybody know what is happening and how to fix this?

I don't think a malfunctioning screen can prevent the phone from booting.
I assume it has something to do with your motherboard, in which case you either replace it or get a new phone.
Yep. The GPU is failing. I bet if he enters recovery mode he'll have a perfectly functioning screen. This is because recovery doesn't use the GPU.
Got my S7 Edge for just over a month now, and yesterday it started showing a black screen from time to time when navigating the phone. Note that I haven't dropped the phone, changed anything to it or made it wet. So after the black screen flickering, it only got worse, the black screen appears everytime for like half a second when i touch the screen, and when it gets noticably hot it simply stays black with rainbow lines flashing over the black screen.
Booting in safemode doesn't help. The flickering seems to be reduced just a little when I put it in the charger.. Not sure why.
I feel let down by Samsung (again), and I am bringing it to the service center tomorrow to have it fixed (and trade / sell it when I get it back) but I wanted to make 1 last cry for help on XDA, since maybe someone has a magical solution that will prevent me being without a smartphone for 2 weeks+.
Thanks a lot in advance.
Nothing we can do.
Factory reset phone is your last resort.
