1 About this manual
1.1 Purpose
This manual is intended to guide DIY hobbyists with certain hands-on skills and repair experience in replacing official
components of vivo phones.
1.2 Caution
All features, characteristics, specifications, and other device information provided in this manual, including but not
limited to device advantages, design, pricing, components, performance, availability, and functionality, are subject to
change without prior notice. vivo reserves the right to modify this manual or any descriptions herein at any time
without the obligation to give notice of such modifications. Please read through this manual carefully before repair. If
you do not meet the repair conditions, do not disassemble the device. You may visit a vivo customer service center for
repairs.
1.2.1 Repair notes
Warning: Failure to follow the instructions herein or the use of non-official vivo components or improper tools may
damage the device, its components, or other property; impair device functionality and water resistance; and in severe
cases, cause fires or other safety hazards, leading to personal injury or death.
(1) vivo assumes no liability for any damage or defects resulting from repairs made by unauthorized carriers, yourself,
or other non-professionals. vivo is not responsible for any device damage, personal injury, or other safety
consequences caused by failure to follow this manual.
(2) Any damage or defects resulting from attempts to repair the device by anyone other than a vivo-certified service
provider are not covered by the warranty.
(3) We recommend that you use only official tools for repairing. Most electronic components are sensitive to
electromagnetic forces, and low-quality tools may easily damage your device. For tool details, see Section 3.1.
(4) We recommend that you use only official spare parts. Third-party spare parts may not function properly and may
cause fires or personal injury.
(5) Some components, such as laser focusing/proximity/fingerprint sensors, rear cameras, touchscreen panels, and
speakers, may require calibration to ensure their performance after repair.
(6) The water and dust resistance of a device repaired by yourself or other non-professionals cannot be guaranteed.
(7) If you need to access device fault data or obtain more detailed diagnostics, please visit a vivo customer service
center.
(8) If you need to replace components that are unavailable on the market, please visit a vivo customer service center
for further assistance.
(9) Before making repairs, back up important data stored in the device.
(10) Before making repairs, wear proper safety gear. vivo is not responsible for any injury due to failure to wear proper
safety gear. For details of the required disassembly and assembly tools, see Section 3.1.
(11) Make repairs in a safe location.
(12) Before making repairs, make sure that the device is powered off and its battery is fully discharged.

(13) If the device is damaged, emits smoke, or produces a burning smell, stop repairing it immediately and contact vivo
customer service. If a fire is started, extinguish it with a carbon dioxide or dry powder fire extinguisher, specialized
foam, sand, soil, gravel, or a dedicated lithium-ion battery fire suppressant.
(14) When repairing the device, wear protective gear such as safety goggles, gloves, and masks.
(15) When removing the back cover, take care not to damage the device. Before reassembling the device, make sure
that no free screws or foreign objects are left around the battery.
(16) During reassembly, inspect the back cover for abnormalities before reinstalling it. Avoid impact or pressure on the
battery to prevent damage. If the battery is damaged, please visit a vivo customer service center.
1.2.2 ESD precautions
Electrostatic discharge (ESD) is a sudden flow of electric current between two charged objects due to contact, a short
circuit, or dielectric breakdown. ESD negatively affects mobile devices, particularly their electronic components.
(1) We recommend that you wear anti-static wrist straps and gloves, and use anti-static mats when you repair the
device.
(2) Increase airflow in the work area to reduce the likelihood of accidental ESD. In an environment with low humidity,
such as an air-conditioned room, ESD is more likely to happen.
2 Warranty
2.1 A 90-day warranty is provided for official spare parts. If any quality issues arise with them within that period, you
may contact vivo for a replacement.
2.2 A device repaired by anyone other than a vivo-authorized service provider is not covered by the warranty, and you
will bear the repair costs.
2.3 Any damage caused during self-service repairs will be your responsibility.
