Galaxy S5 mini LTE schematic for the Samsung SM-G800F, a 10.2 MB PDF document. It is meant for component-level work on this particular variant: following power distribution from the PMIC, checking charging and USB paths, tracing antenna and RF sections, and locating parts around a failed rail. Open it with any standard PDF reader and search by reference designator. Samsung variants that share a model family can still differ in RF and memory sections, so confirm the exact model code first.
