Frequently Asked Questions — Apple Device Repair

Yes, absolutely. At Hida Info, we offer both 100% Genuine specification displays and components as well as Grade-A OEM replacement parts, giving you flexible choices based on your budget. Every screen replacement includes TrueTone programming, original touch calibration, and Face ID integrity preservation.

All hardware replacements (screens, batteries, charging ports, back glass) and motherboard repairs are backed by our documented service warranty for 3 months (90 days). This covers manufacturing defects and functional issues with prompt resolution.

Walk-ins are always warmly welcomed 7 days a week at our Chandni Chowk E-Mall shop. However, sending a quick message on WhatsApp or booking in advance ensures zero wait time and that your specific replacement part is pre-allocated in our active inventory.

We accept all major payment methods including Cash, UPI (Google Pay, PhonePe, Paytm, BHIM), Credit Cards, Debit Cards, and Net Banking for a seamless checkout experience.

Hida Info has been operating in Kolkata for over 14 years (established 2012) under the technical leadership of founder Mr. Mojahid Reza. Over the years, we have repaired over 15,000 Apple devices and smartphones with top ratings across Google (4.9★, 390+ reviews) and Justdial (5.0★, 375+ reviews).

Yes, 100%. For all standard hardware repairs such as screen replacements, battery changes, camera repairs, and charging port fixes, your personal data, photos, accounts, and applications remain completely untouched. We maintain strict customer privacy protocols.

Yes, 100%. We use specialized EEPROM programmers to read the serial calibration data from your original damaged screen and rewrite it to the new display, ensuring TrueTone continues to work seamlessly. Additionally, we meticulously transfer your original Face ID sensor and ambient light sensor flex cable without damaging the biometric sensor.

For iPhone XS and newer models, Apple's iOS displays an "Unknown Part" notice if the original Battery Management System (BMS) circuit board isn't retained. At Hida Info, our technician Mr. Mojahid Reza can perform precision spot-welding to transfer your original BMS chip to the fresh Grade-A battery cell and reset the battery health cycle counter, allowing your iPhone to display a clean 100% maximum capacity without persistent error alerts.

Yes! If your device's internal OLED or Retina display panel is completely functioning without vertical lines, black ink spots, or touch issues, you do not need an entire expensive screen assembly. We use industrial freeze separators and vacuum OCA laminating chambers to replace only the cracked outer glass. This saves you up to 60–70% compared to a full screen replacement while retaining your genuine factory Apple display panel.

Yes. If you cannot visit our Chandni Chowk E-Mall workshop in person, we offer verified doorstep pickup and return delivery across Central Kolkata, Salt Lake (Bidhannagar), New Town, Rajarhat, South Kolkata, and Howrah. Your device is securely packaged with tamper-proof seals, inspected on video upon arrival, and returned to you safely once repaired.

Yes. We have specialized ultrasonic cleaning equipment and professional micro-soldering stations to treat corroded logic boards from water damage. If your device has suffered a spill, bring it in immediately without charging to maximize the recovery rate.

Most common repairs — including iPhone screen replacement, iPhone battery renewal, and Apple Watch glass fixes — are completed within 30 to 90 minutes. Complex logic board diagnostics and liquid damage treatments typically take 24 to 48 hours for exhaustive reliability testing.

Yes. We believe in 100% pricing transparency. We inspect your device, identify the exact component or circuit fault, and provide a clear quotation before starting any work. There are zero hidden costs.

We are situated inside Chandni Chowk E-Mall, Shop No T318 on the 3rd Floor (6 C.R. Avenue, Kolkata 700072). It is directly adjacent to Chandni Chowk Metro Station (Gate No 1). Escalators and elevators are available inside the mall.

Yes! Chandni Chowk E-Mall is a fully air-conditioned retail hub with dozens of gadget, computer, and electronics stores. You can relax, shop, or grab a beverage while our technicians service your phone or laptop.

Yes. Unlike standard service centers that force customers into expensive complete motherboard replacements, Mr. Mojahid Reza specializes in micro-soldering BGA chips, power management ICs, backlight fuses, and shorted capacitors, saving you up to 70% in repair costs.

Yes, in many cases it can! The notorious green vertical lines or solid white screen issues on iPhone 13/14 Pro series and OnePlus flagships are frequently caused by damaged display flex cable circuits rather than a physically shattered panel. Rather than forcing a costly screen swap (which can cost ₹30,000+ at Apple Stores), we perform micro-laser jumpering and flex bonding repair at a fraction of the cost.

Immediately disconnect the MagSafe or USB-C charger and do not attempt to power it on. Never place your MacBook in rice, as rice starch accelerates electrical corrosion inside the logic board. Keep the laptop inverted in an open tent position to prevent moisture from dripping deeper into the keyboard and logic board, and bring it directly to our Chandni Chowk workshop for emergency ultrasonic chemical drying and board-level repair.

During Apple Watch repairs, we thoroughly clean off the old deteriorated factory adhesive and install custom, laser-cut OEM waterproof perimeter gaskets. The watch is then cured under calibrated compression clamps. While we advise against deep scuba diving or hot saunas with any repaired electronics, our resealing process reliably restores everyday splash and rain resistance.

Yes. Foldable smartphones require specialized equipment. We service Samsung Galaxy Z Fold & Z Flip series as well as OnePlus Open repairs, including Ultra-Thin Glass (UTG) replacement, inner flexible AMOLED screen renewal, flex ribbon cable restoration, and stiff or misaligned hinge gear repair.
