There are over 2,000 phone repair shops in Bangalore. Maybe 200 are excellent. Maybe 400 are good enough. The rest range from mediocre to actively dishonest — and the dishonest ones look identical to the honest ones from the outside.

The good news: you don't need to research every shop. You need 9 questions you ask the shop directly, and the answers tell you almost everything. This checklist is what we'd give a family member walking into an unfamiliar shop in SP Road or Brigade Road with a cracked phone.

Most of these questions can be asked on a phone call before you even leave home. If a shop hesitates or gets defensive on more than 2 of them, walk away.

1. What grade of parts do you use?

There are four tiers of replacement parts in Bangalore's market — most customers don't know they exist. A good shop volunteers this distinction. A bad one says "original" and refuses to elaborate.

  • OEM (Original Equipment Manufacturer): Genuine Apple/Samsung/Xiaomi parts. Most expensive. Only authorised service centres get reliable supply.
  • Refurbished OEM: Original parts pulled from donor devices, refurbished. Often the best price-to-quality ratio. Honest shops will tell you this is what you're getting.
  • Premium aftermarket (often called "Incell" or "Soft OLED"): Made by reputable third-party manufacturers. Visually similar to OEM, often 80–90% performance. Real category, not a scam.
  • Budget aftermarket: Cheapest copies, often TFT pretending to be OLED, washed colours, touch lag, fail in 3–6 months.

Good answer: "We use refurbished OEM for iPhone screens and premium aftermarket for Android — let me show you the part before fitting."
Bad answer: "Original sir, all original" without any further detail.

2. Will you show me the new part before installing it?

The single most effective anti-scam question. A shop that won't open the box in front of you is a shop swapping a premium-priced part for a cheaper one behind the curtain.

Honest shops happily unbox the part, point out the part number, the manufacturer sticker, and the QC seal. Some even let you photograph the part for your own records.

Bonus question: Ask to watch the repair. Many shops have a customer viewing area. If they refuse outright, that's a red flag. Doorstep services do this by default — the repair happens in front of you at your home.

3. What's the warranty — in writing?

A verbal warranty in Bangalore is worth nothing. Shops change locations, change owners, change names — and "but you told me 6 months" gets you nowhere without proof.

What good warranty looks like:

  • Printed on the GST invoice with the shop's stamp/signature
  • States the duration clearly (e.g. "6 months from date of repair")
  • States what's covered (the part itself, not accidental re-damage)
  • States how to claim (return to this shop, free re-installation)

Typical 2026 warranty by part: Screens 3–6 months, batteries 6–12 months, charging ports 3 months. Anything less than 3 months suggests the shop expects the part to fail.

4. Can I see the old part you removed?

A scam that's been quietly happening in Bangalore for years: you bring in a phone for screen replacement. The shop replaces the screen — but also swaps out a perfectly good battery, motherboard, or camera with a worse one from a donor phone. You walk out happy. Three months later, the new "old" part fails.

The fix: at the start of the repair, ask the technician to keep all removed parts in a small zip-lock bag and hand them to you at the end. Honest shops do this without being asked.

If a shop refuses or says "we recycle the parts immediately, sir" — leave. Recycling can happen after you've inspected what came out.

5. Do you have a GST invoice and registered business name?

The single fastest way to filter out fly-by-night operations. Registered businesses with GSTIN have a paper trail, can be sued in consumer court, and lose more by scamming than by being honest.

Ask: "Can I get a proper GST invoice with your shop name and GSTIN?"

Three possible responses:

  • "Yes, full invoice" — green light
  • "We give a bill but no GST" — yellow light. Could be small genuine shop, could be unregistered. Check Google Maps listing.
  • "GST extra 18%, sir" — yellow light. Often means the headline price was misleading. Ask for the all-inclusive total.
  • No invoice at all — red light. Don't proceed.

6. How do you handle my data during repair?

Phone screens, batteries, and charging ports can all be replaced without unlocking the phone. If a repair technician asks for your passcode or pattern for a hardware repair, push back hard.

Legitimate reasons to need passcode: software-related repair (boot loop, OS reinstall, factory reset), some Touch ID/Face ID repairs, post-repair functional testing.

Best practices to ask for:

  • Repair happens in a customer-visible area, not a back room
  • For software repair, the technician resets the passcode after work and tells you
  • If your phone must leave the counter for workshop repair, you sign a custody form noting condition

Doorstep services solve this entirely — your phone never leaves your sight. See our doorstep mobile repair safety guide for the full data-security framework.

7. What happens if you can't fix it?

This question separates professional shops from the rest. Good shops offer one of two policies:

  • No fix, no pay — if we can't restore function, you pay nothing (not even the diagnostic fee)
  • Diagnostic fee + repair fee — clear upfront. The diagnostic fee (usually ₹200–500) is charged whether or not you proceed with the repair, but it's stated before the phone is opened.

Red flag: "We don't know until we open it, sir" with no upfront fee disclosure. This is the standard set-up for a "₹500 diagnosis turned into ₹4,000 motherboard work I didn't authorise" complaint.

Get the worst case in writing. Maximum repair cost should be capped before the phone is opened.

8. Are the reviews and reputation real and recent?

Google reviews are easy to game but hard to game well. Here's the 90-second check:

  • Total review count: Established Bangalore shops have 200+ reviews. Under 30 is either new or fake.
  • Review age distribution: Real shops have reviews spread across 2–5 years. 80% of reviews in the last 30 days = bought.
  • Negative reviews: Real shops have some 1-star reviews. A 5.0 rating with 500+ reviews is statistically impossible.
  • Owner responses to negatives: Good shops respond professionally to negative reviews. Defensive, generic, or no response = bad sign.
  • Review content specificity: "Great service" × 200 = fake. Reviews that mention specific repairs ("got my iPhone 13 screen done", "Whitefield doorstep on Sunday night") = real.

Also check JustDial and Sulekha briefly — fake review farms often hit only Google.

9. Is the price all-inclusive?

Hidden charges are the most common Bangalore phone repair complaint. The "₹2,500 screen replacement" becomes ₹3,800 by the time the customer leaves because:

  • + ₹500 "labour charge" added at billing
  • + ₹300 "tempered glass mandatory with new screen"
  • + 18% GST not previously mentioned
  • + ₹200 "diagnostic" even though it was advertised as free

The fix: before the phone is opened, get one number — the all-inclusive final amount. Confirm it includes parts, labour, GST, and any "service charge". If they hesitate to commit to a number, walk away.

The 60-second decision framework

When you don't have time for the full checklist, run this quick filter on any shop:

  1. Pricing transparency on call — do they give you a number, or just "bring it in for inspection sir"?
  2. Written warranty — confirm before handing over the phone
  3. Watching the repair — possible? If not, why not?
  4. Old part returned — yes or no?
  5. Reviews look real — 200+ reviews, spread over years, owner replies?

5 out of 5 yes = go ahead. 3 out of 5 = ask harder questions. Below 3 = find another shop.
