Cracked glass, damaged panels, black screens, green lines or touch faults: original-quality OLED replacement, with Face ID and True Tone tested on site. Most take 20–30 minutes.
Battery health below 80%, unexpected shutdowns, heat or rapid drain? Quality on-site replacement in as little as 15–30 minutes, with charging and discharging tested before collection.
Screen and battery replacement plus full function checks for iPad, iPad Air and iPad Pro. We test Apple Pencil writing and pairing before collection. Most repairs take under 1 hour.
Keyboard faults, swollen batteries, cracked screens or startup failure after liquid exposure: experienced technicians open and inspect the logic board, then provide a written quote before work.
Galaxy S, Note and A series, plus Z Fold and Z Flip foldables: AMOLED display, battery and logic board repairs, followed by under-display fingerprint and camera testing.
Pixel screen damage, ageing batteries, charging faults and liquid damage: professional inspection and on-site repairs, most completed within 1 hour.
Phone will not start, gets hot or draws excessive current after liquid exposure? We open it, chemically clean the board and repair shorted areas, prioritising a backup once it starts.
Phone will not charge, needs a particular angle or cuts in and out? We identify dust, corrosion or flex cable damage before cleaning or replacing the charging-port flex cable, then test it on site.
Pre-repair backups or recovery of photos, contacts and files after liquid damage, startup failure or board faults. We assess feasibility and report results honestly.
For freezing, stalled updates, app crashes, slow response or account lockouts, we distinguish software from hardware issues first. Many can be resolved without replacing parts.

In-Depth Guide
Last updated: October 2026
Many people immediately consider a new phone when theirs breaks, but replacement may be unnecessary. Consider three things. First, Extent of damage: if only the display, battery or charging port is faulty and the board works, repair usually costs a small fraction of a new phone. Second, Device age and performance: if the phone still meets your needs and only the battery has aged, replacement generally improves runtime and smoothness. Third, Value of your data: if many photos and work files are not backed up, repair is often more practical than replacement. Conversely, severe board corrosion or simultaneous screen, battery and board damage may bring repair costs close to replacement. Compare carefully. A free inspection and actual quote are always better than guesswork. For detailed guidance, see iPhone Repair page.
Official or authorised service uses genuine parts backed by the manufacturer, suiting users under warranty or prioritising genuine components. However, waiting may take days and out-of-warranty fees are generally higher. For example, Apple's Hong Kong website lists an estimated HK$3,249 for out-of-warranty iPhone 18 Pro screen damage (October 2026; check the latest official prices). Independent specialists, including ours, offer same-day collection, clear pricing and acceptance of expired warranties, parallel imports, used phones and previously opened devices. This suits urgent needs or out-of-warranty phones. Avoid mobile stalls without permanent premises because addresses and parts origins are difficult to verify.
| Criteria | Official / Authorised Centre | Our Shop (Independent Specialist) | Stall With No Fixed Shopfront |
|---|---|---|---|
| Turnaround | May take several days | 20-30 min, same-day for most repairs | Depends on vendor, hard to guarantee |
| Price Transparency | Official pricing | Transparent, quote confirmed before work | Transparency varies |
| Out of warranty / parallel import / previously opened | Some cases cost more or may not be accepted | Accepted — diagnosed then quoted | Accepted, but quality varies |
| Warranty Follow-up | Manufacturer warranty | Written warranty and a physical shop for follow-up | Often verbal promises only, making follow-up difficult |

Under Settings → Battery → Battery Health & Charging, Maximum Capacity shows current capacity as a percentage of when new. Apple states that iPhone 14 and earlier batteries are designed to retain around 80% after 500 complete cycles under ideal conditions, rising to 1000 for iPhone 15. A cycle means cumulatively using the equivalent of 100%, not necessarily all at once. Consider replacement below 80%, with unexpected shutdowns, shutdowns in cold weather or noticeably slower apps. For details, see iPhone Battery Replacement.
After liquid exposure, switch off immediately, do not retry startup or charge, dry the outside and have a technician inspect the board promptly. Liquid causes short circuits and continuing contact corrosion, even after the outside dries. Delay reduces recovery chances. Apple states that liquid damage is excluded from its one-year limited warranty, and iPhone liquid contact indicators turn red when wet. Water and splash resistance are not permanent and weaken with normal use, so IP68 does not mean immune to water damage.
Common myth: Can rice or a hairdryer help? Neither is recommended. Rice particles and dust may enter openings; heat can drive moisture deeper and deform plastic parts or batteries. Switch off, dry the outside and seek repair promptly. See Phone liquid damage repair. For photo recovery, see Data recovery.
Not necessarily. Try another cable and charger to rule out accessories. If it still fails, dust or corrosion may be responsible and cleaning may resolve it. Replacement is needed only if the flex cable is damaged. iPhone 15 and later use USB-C, so diagnosis differs from older Lightning models. We inspect before deciding and test charging and data transfer afterwards. See Charging Port Repair.
Most mid-range and high-end Samsung phones use AMOLED displays, which may develop burn-in after prolonged static images. Once it occurs, the whole display usually needs replacing. The inner-screen protective film on Z Fold and Z Flip is part of the device's structure; do not peel it off yourself. Cracks in an iPad screen can spread even if it still works, and may cut fingers or damage Apple Pencil tips. A swollen MacBook battery is a safety concern and should be replaced promptly. See Samsung Repair, iPad Repair and MacBook Repair.
