First PDF of a multi-part schematic for the Samsung Galaxy J3, model SM-J330, about 642 KB. The name marks it as part one, and the other files continue the set. Use it to identify circuit blocks, follow rails from the battery and PMIC, and find parts that sit on a shorted line. Any PDF reader opens it, and searching by part or net name speeds work. The SM-J330 has regional variants, so compare the model code and board label on the handset first.
