my phone's front camera suddenly stopped working!!i bought the phone only 4 months ago..suddenly without any accidents it stopped working.i didnt drop it anywhere or it didn’t have any damages at all.i restarted the phone,cleared all caches,tried 3rd...

As i dont have a earphone jack in my phone so I've to use a type c dongle to use an earphone. but my the USB driver isn’t working.any suggestions please?

I'm suffering for want of a slow motion feature on my SSamsung galaxy m30.will i get it?
