🔧 Introduction
Let’s face it—cracking your phone screen feels like stepping on LEGO with bare feet. Bolesny, nieoczekiwany, i drogie. Ale hej, what if you could replace it yourself? Welcome to the ultimate guide that shows you how to do exactly that—whether you’re dealing with an iPhone or Android. We’ll walk you through everything step by step, with photos or video links, and throw in risk warnings to make sure you don’t turn your phone into a paperweight.
🔩 Essential Tools & Materials
Basic Toolkit for Screen Replacement
To get started, you’ll need:
- A precision screwdriver set (usually with Pentalobe, Phillips, Tri-point heads)
- Suction cup
- Plastic prying tools
- Tweezers
- SIM card ejector tool
- Isopropyl alcohol (for cleaning)
Recommended Safety Gear
- ESD wrist strap (prevents static damage)
- Anti-static mat
- Safety glasses (screens can shatter while removing)
How to Source Quality Replacement Screens
Not all screens are made equal. Avoid super cheap ones on shady marketplaces. Look for:
- OEM or OEM-like labels
- Gwarancja (even 30 days is better than none)
- Verified compatibility with your phone model
⚠️ Risk Alerts Before You Start
Voiding Your Warranty
Once you open the device, say goodbye to warranty claims. Think twice if your device is still under warranty or AppleCare.
High-Risk Parts You Might Break
- Fingerprint scanners (Touch ID, under-display)
- Face ID modules (on iPhones)
- OLED panels (very fragile, especially on Samsung)
Static Damage and ESD Risks
Static electricity can fry delicate components. Use ESD protection and ground yourself.
When You Shouldn’t DIY
- If the screen is fused to the battery
- If you lack steady hands or patience
- If the phone has water damage
🛠️ Step-by-Step Disassembly Process
Krok 1: Power Down and Discharge the Battery
Hold down power and shut off the phone. Wait 2–3 minutes to let capacitors drain.
Krok 2: Remove Screws and Open the Device
iPhone
Use a Pentalobe screwdriver to remove the bottom screws near the charging port. Apply a suction cup to the screen and pry gently with a plastic tool. Don’t insert too deep!
Android
Depends on model. For Samsung, heat the edges with a heat gun (70–80°C), use suction and a plastic card to separate the glass. For Xiaomi or OPPO, screws may be under the back panel.
Krok 3: Disconnect the Battery First!
Never skip this. Disconnecting the battery first prevents short-circuiting the logic board.
Krok 4: Label and Disconnect Flex Cables
Use tweezers or a spudger to carefully detach flex cables connecting the screen, kamera, or sensors.
Krok 5: Remove the Broken Screen Carefully
Once all cables are off, lift off the screen. Be gentle. Some devices have adhesive you’ll need to soften with heat again.
📲 Installing the New Screen
Krok 6: Clean the Housing and Reapply Adhesive
Scrape off leftover glue. Use alcohol and lint-free cloth. Apply new adhesive strips or glue.
Krok 7: Connect Flex Cables to the Logic Board
Reconnect display, digitizer, front camera, etc. Be firm but careful.
Krok 8: Reconnect Battery (Last Step!)
Once everything is in, reconnect the battery and secure it.
Krok 9: Reattach Screws and Seal the Device
Replace the back panel or screen, apply even pressure, and screw it all back in.
🧪 Testing Before Final Assembly
Before sealing everything up permanently:
- Touch responsiveness
- Jasność & display colors
- Martwe piksele
- Front & rear camera function
- Face ID or fingerprint reader
If anything’s off, reopen and check the connectors.
🚫 Common Mistakes to Avoid
Forgetting to Disconnect the Battery
This is the #1 cause of blown backlight circuits or damaged logic boards.
Pinching Cables or Misaligning Connectors
Flex cables are like veins—if you pinch or twist them, they can tear internally.
Overtightening Screws
This can crack the glass from internal pressure. Snug is enough.
🔍 Special Notes by Device Brand
iPhone X and Later: Face ID Warning
Face ID components are sensitive. Damaging them = permanent loss of Face ID. You can’t just replace them—Apple’s system pairs them with the logic board.
Samsung Edge Displays: OLED Fragility
These bendy screens are super delicate. Applying too much heat or pressure can ruin them before you even finish.
Xiaomi & Oppo: Battery and Screen Integration
On some models, the screen is adhered directly over the battery. You risk puncturing the battery if you go too deep.

👨🔧 Should You Hire a Pro Instead?
Cost Comparison: DIY vs Shop
- DIY: $20–$80 for parts
- Shop: $50–$150+ depending on model
DIY saves cash—but only if done right the first time.
When a Repair Tech Saves the Day
- If your phone is your only lifeline
- If the job involves motherboard soldering
- If you’re replacing both front and back glass
🧠 Final Thoughts
Swapping out your phone screen can be super satisfying—like fixing your own bike for the first time. But it’s also easy to mess up if you’re not prepared. If you’re careful, use the right tools, and follow guides like this, you can save money and level up your repair game.
But hey—if you’re unsure or your phone is a flagship model, it’s perfectly okay to let the pros handle it.
