If you are repairing a Vivo U10 and cannot find the schematic, consider:
If your Vivo U10 doesn't turn on, a schematic helps you trace the Primary Voltage Rails (VBATT, VPH_PWR, VREG). You can locate test points for the PMIC (likely a Qualmit PM6125) and check if voltage is reaching the power button.

If you are a mobile technician looking for this file, here is the standard procedure to obtain it:
A: Yes. The fingerprint sensor is typically mapped to the power management IC via an SPI bus. The schematic will show the FPC connector pins (FPS_IRQ, FPS_RST). If you are repairing a Vivo U10 and
A genuine Vivo U10 schematic diagram is typically 20 to 50 pages. Here is a breakdown of the most important pages:
| Page Type | Description | | :--- | :--- | | Power Distribution | Shows how battery voltage is stepped down to 1.8V, 3.1V, and 4.4V. | | Charging Circuit | Details the charging IC (often BQ25601), coil, and protection MOSFETs. | | Audio & Headphone | Audio codec (WCD9370) pins, microphone bias, and speaker amplifier. | | RF (Radio Frequency) | Antenna switches, signal filters, and PA (Power Amplifier) for 4G bands. | | SIM & SD Card | Pinout for the dual SIM tray and microSD card detection lines. | | Keypad & LED | Volume button, power button, and notification LED anode/cathode points. | Pro Tip: Look for the "TEST POINT" or
Pro Tip: Look for the "TEST POINT" or "ALT" (Alternate) sections. These are lifesavers when the original pads are ripped off the board.
A schematic diagram, often called a "service schematic" or "circuit diagram," is a detailed map of the electrical circuits inside the Vivo U10. Unlike a block diagram that shows general functions, a schematic provides:
For the Vivo U10—a budget-friendly phone released in 2019 running a Snapdragon 665—common issues include charging port failure, screen flickering, and dead microphone. All of these can be fixed with the correct schematic.
