I just purchased a Note4 from Sprint. Instead of porting the number for me, they gave me a new number. I am trying to program my old number on the device. How do I get the programming code? any help would be appreciated. Thanks.
It will be better if you contact Sprint people in regard of this as it is their job and they will do it for free.
Yeah, these codes do not work on a Verizon Note 4. So the statement that it works on all the models of galaxy series is false.

As I can see your phone’s hardware is damaged as shampoo may have destroyed it.
To repair it you need to go to service center otherwise you can just keep using your phone as normal.
My S4 becomes too hot at times. When switched off for a while it becomes normal. What could be the cause?
There can be many issues because of which your phone may get heat like – cover blocking the heat flow, many applications running in the background, low signals, battery issue or charging issue.
Can you please tell how old is your mobile and when it gets heated the most.
