Fixing Phone Yourself? 5 Massive Risks That 10-Min Videos Don't Show You

Your phone screen is cracked. You go to YouTube, type "DIY phone screen replacement," and a 10-minute video pops up. The person in the video makes it look so easy.

You think, "I can do this. Why pay a shop when I can do the fixing phone job myself and save money?" Hold on, boss. Let's talk.

The "Looks Easy on YouTube" Trap

Abang FixBay here. Look, I get it. You’re smart, you're capable, and you want to save a few Ringgit. I respect that. But I’ve seen the "aftermath" of these DIY fixing phone attempts. The videos are designed to look simple. They edit out the parts where they struggled for 20 minutes, they don't show you the tiny, paper-thin cables that can tear if you just breathe on them wrong.

They make fixing phone problems look like building with LEGOs. Let me be the "abang" (big brother) who tells you the truth: it is not.

Modern smartphones are tiny, complex miracles of engineering. They are not designed to be opened by untrained hands. Before you turn a simple, fixable problem into a haru-biru (chaotic) disaster, let's talk about the real risks of fixing phone issues yourself.

5 Massive Risks of DIY Phone Fixing (The "Haru-Biru" List)

That "RM50 screen" and "DIY toolkit" you bought online can quickly become the most expensive mistake you’ve ever made. Here are the top 5 disasters I see every single week at our FixBay branches.

1. The "Bye-Bye Face ID" Disaster (The Unseen Cable)

This is the most common and heartbreaking one. When you’re attempting a fixing phone screen replacement, you have to disconnect the earpiece and sensor assembly.

• The Problem: This assembly contains the "flood illuminator" and "dot projector" for your Face ID (on iPhones) or sensitive fingerprint sensor cables (on other models).
• The Disaster: This cable is extremely fragile. If you tear it—and it's so, so easy to tear—your Face ID or biometric sensor is gone forever.
• The Hard Truth: This component is "paired" to your phone's unique motherboard. You cannot just replace it. No one can. There is no fixing phone sensor after it's torn. You will have a working screen, but you'll be typing in your password for the rest of that phone's life.

2. Buying "Cap Ayam" (Fake) Parts Online

You search online for a "phone battery." You find one that’s super cheap. You think you’ve got a great deal.

• The Problem: The online marketplace is flooded with low-grade, fake, or "cap ayam" parts. These parts are not tested for safety or quality.
• The Disaster:
  • Fake Screens: They have bad colours, terrible touch response, and crack with the slightest tap.
  • Fake Batteries: This is the dangerous one. Cheap batteries can swell up, overheat, or (in the worst cases) catch fire.
• The Hard Truth: Your fixing phone attempt ends with a phone that is either worse than before or is now a serious safety hazard.

3. The "Wrong Tool, Big Problem" (Stripped Screws & Punctured Batteries)

That "free" toolkit they give you with the cheap screen is usually made of soft metal.

• The Problem: Phones use tiny, specific screws (like pentalobe). Using a cheap tool can easily "strip" the screw head.
• The Disaster: Now that screw is stuck. Forever. You can't open the phone, and you can't close it properly. I’ve seen people try to drill them out. Don't.
• Even Worse (The Battery): People use a sharp metal tool to pry out the old battery. The battery is held in with super-strong adhesive. If you puncture that lithium-ion battery... you will see sparks, smoke, and possibly a fire. It’s a chemical reaction you do not want to see in your living room.

4. The Motherboard "Murder" (From Simple Fix to Total Death)

This is the one that turns a small problem into a dead phone.

• The Problem: You’re fixing phone speaker, and your screwdriver slips. It scratches the motherboard.
• The Disaster: You just cut a microscopic trace on the "logic board." Or, you created a tiny short-circuit. Or, you knocked off a component the size of a grain of sand.
• The Hard Truth: The phone is now completely dead. It won't turn on. What was a simple speaker issue is now a complex, expensive (or impossible) motherboard repair. This is how you turn a RM150 fix into a RM2000 paperweight.

5. The "It's Back... Oh Wait" (The Fix Doesn't Last)

Let’s say you did it. You survived. You replaced the screen, and it turns on! You feel like a genius.

• The Problem: You didn't use the right waterproof adhesive. You didn't seat the cables correctly.
• The Disaster: Two weeks later...
  • A "dead spot" appears on your screen.
  • The screen starts lifting up from the frame.
  • The colours look weird.
  • Dust is getting under the screen.
• The Hard Truth: A professional fixing phone job comes with a warranty. Your DIY job comes with zero guarantees and a lot of extra headaches.

So, When is DIY Fixing Phone Okay?

Abang FixBay will be honest with you.

If your phone is super old and you don't care if it dies, and you want to do it for fun? Go for it, treat it as a learning experience.

If you have a software problem (like an app crashing)? Sure, do a reset.

If your charging port is full of lint (fluff)? You can very gently try to clean it with a non-metallic tool (like a wooden toothpick).

But for any hardware fixing phone job that involves opening the device—screen, battery, camera, charging port—it is just not worth the massive risk.
