Not getting notifications while phone closed

Hello Everyone !

Im having a pretty weird problem over here ...

I use a Note 4 stock and since a while whenever my phone is closed... Im not getting any notifications on screen or with the blinking light

If i just open it in the lock screen im getting my facebook/snapchat pops on screen + blinking light

I checked every options possible in the phone and checked everything possible... I really dont know what to do anymore except to format the phone... which i'd prefer not to do :P

Can anyone help me out ? Thx so much :D

I JUST Closed the BOOTLOADER?!!!!

So after 2 years with the bootloader closed... now my bootloader is with the status again on NO, i mean, "Bootloader unlock allowed: NO"

is this normal? if you relock your bootloader this is what happens?

also, is ther a way to unlcok it again? without needing to send it to sony again?çç


thanks
