I'm guessing this is not normal?





There is Magic Smoke that is trapped inside all electronics devices.
The Magic Smoke has escaped those components.
You must replace those components with new components that have the Magic Smoke still imprisoned in them.
Then your S3 will function again.

Seriously, from your pics, looks like a couple of SMD (Surface Mount Device) resistors/capacitors experienced an excessive over current condition.
Can't read the litho on the card next to the components in your pics. RXXX = a resistor, CXXX = a capacitor where XXX is the component number.
Take a que-tip dipped in iso-propol alcohol and clean off the charring next to those components to be able to read the litho on the circuit card. Make sure you're well grounded when doing this, else static electricity might toast something else.

To read the markings on the components that identify their values you'll likely have to look at another undamaged machine.
This type of component is dirt cheap, shipping on new parts will likely exceed the cost of all those components combined. We're talking a total order $$$ amount under $25.
They can be ordered from a plethora of online sources. I order a lot from Digikey cuz' they're nearby and shipping times are brief.
Once obtained and still being well grounded, de-solder the burnt parts and solder in the new.

Identifying why the Magic Smoke escaped those components is of particular interest to me and likely to others.
