Help Sound, video and calls not working at all Galaxy s5

[I Moss]

On Monday night my Galaxy s5 was working perfectly well... but I woke up on Tuesday to find that it wasn't allowing me to play any videos - on YouTube, Facebook, Snap chat, my gallery or anywhere else. I also realised there was no sound at all on my phone not even for notifications. Later in the day I also noticed I was unable to make or receive any calls.

I have literally tried everything to no avail!! I cleared all my app caches, made sure I had evey software update, cleared the cache partition in recovery mode and even did a factory reset. I'm getting so frustrated!

Any help would be really, really appreciated. I've only had the phone for two weeks so I'm very disappointed!

Seems that you have tried all the trouble shooting steps I would recommend.
If the stock firmware is available for your model number, you could try to flash it using Odin.
Since you have only had it for a few months and if it is possible to return for a replacement, that might be the best choice.
