Small PDF reference sheet of about 53 KB for a device labelled Note 10S, focused on the MIPI switch IC and the switch board, with diode-mode measurement values. Such diode readings are compared against a faulty board with a multimeter in diode mode to spot open or shorted lines around display or camera MIPI signals. The exact phone brand is not stated in the name, so confirm the model and board version before relying on the values. Measurements should be taken with the device powered off and the battery disconnected.
