The Honor 400 is designed to deliver smooth performance, an impressive display, and advanced camera features for everyday smartphone users. However, even well-built devices can encounter problems after long-term use or accidental damage. Issues such as cracked screens, battery wear, charging problems, or motherboard faults can affect the phone’s overall performance.
At Hitec Mobile, we provide reliable Honor 400 repair services in Singapore with experienced technicians and professional diagnostic tools. Our goal is to restore your phone’s performance efficiently while maintaining the quality and reliability expected from your device./p>

A damaged screen is one of the most common smartphone issues. If your Honor 400 display is cracked, showing coloured lines, black spots, flickering, or touch responsiveness problems, it may require a screen replacement.
Our Honor 400 screen replacement service restores both the display quality and touch sensitivity. Using high-grade replacement panels, we ensure the brightness, colour accuracy, and smooth touch response return to normal. After installation, the device undergoes detailed testing to confirm the display functions correctly.

Smartphone batteries naturally degrade after repeated charging cycles. If your Honor 400 battery drains quickly, struggles to hold charge, overheats, or shuts down unexpectedly, replacing the battery may be necessary.
At Hitec Mobile, we perform Honor 400 battery replacement using reliable replacement batteries designed for stable performance and long-lasting usage. The repair includes safe battery removal and proper installation to ensure optimal power efficiency.

Charging port issues can cause the phone to charge slowly, disconnect frequently, or fail to detect the charging cable. This problem often develops due to daily wear, debris buildup, or liquid exposure.
Our Honor 400 charging port replacement service resolves these issues by replacing the faulty charging connector and restoring reliable charging functionality. The repair also ensures stable data transfer when connecting the phone to a computer.

Accidental exposure to liquid can lead to internal corrosion and circuit damage if not treated quickly. Even small amounts of moisture can affect the phone’s internal components over time.
Our water damage cleaning service involves carefully disassembling the device, removing moisture residue, and cleaning the motherboard and connectors. Early intervention greatly improves the chances of preventing long-term damage.

When a phone experiences problems such as no power, unstable performance, network failure, or charging issues that are not related to external components, the motherboard may require repair.
Hitec Mobile offers advanced motherboard diagnostics and repair, allowing technicians to locate faulty circuits or damaged chips and repair them at the component level. This approach often helps reduce repair costs while preserving the phone’s original hardware.
