- Gently release the buttons once the Logo appears.

Method 2: Fixing Galaxy S3 stuck at Samsung Splash Screen by Restoring Original Firmware
I can see that your device probably experience soft-bricks. Soft-bricks only occurred if you installed a wrong kernels and images from rooting or installing custom ROMs. This problem cannot be easily fix by simple hard reset, it’s because the firmware is already damaged or corrupted and then the device will not been able to boot normally.
Why the heck I said wrong root kernels and images and so on.. that ended up bricking your phone?
Possibly you root it and or installed a custom rom that was built for GT-I9300 (international) on your U.S or Canadian Galaxy S3 (SGH-I747/M, SGH-T999/V, SCH-I535 and SPH-L710). This should not work out, for each variants has its own specific firmware builds.
So, in order to fix such problem; You need to fully restore back your Samsung Galaxy S3 official and original firmware. Soft-bricks oftentimes strikes the Bootloader image area of your phone’s operating system, that is why it’s just stuck on Samsung splash screen and won’t boot in normal mode further.
The first proven and working method is by restoring a bootloader images unto the device by means of manual flashing. And then last attempt is to fully re-install back the Galaxy S3 original firmware.
Samsung Galaxy S3 I747, AT-T
Samsung Galaxy S3 T999, T-MO
Samsung Galaxy S3 L710, Sprint
Samsung Galaxy S3 I535, Verizon
For international version Galaxy S3 GT-I9300 and all Canadian version, it can also be repaired by restoring back the original stock firmware. Just find any available original stock firmware according to your device country/provider originated.
If this methods fix your phone, just be cautious in the future and don’t let it happen again. It’s not easy anyway, especially if you’re not a tech-savvy.
However, if those method above doesn’t fix your problem, then there’s nothing I can add here. But, I suggest you – to return back your phone to your dealer and tell something that might encourage them to have your phone fix for free or have it exchange for a new one.
