Schematic for the Samsung Galaxy S10 Plus, model G975U, the US variant designation, compressed into an 8.58 MB RAR. These pages are used to follow power rails from the battery and PMIC, trace charging and USB-C lines, and locate components around a shorted net on a dead or rebooting phone. Unpack with 7-Zip or WinRAR and view in a PDF reader. The US model uses different radio hardware from international versions, so verify that your handset is the G975U before trusting RF or modem sections of the drawings.
