Introducere
Aşa, you’ve just had your phone screen replaced—awesome! But wait, it’s not over yet. Think of it like getting a new tire on your car. You wouldn’t just slap it on and hit the road without aligning and testing it, corect? Same goes for your screen. If you want it to work just like the original (or better!), there are a few key things you must do post-replacement.
Let’s walk you through everything step-by-step—from calibration to waterproofing and full-on diagnostics—to make your phone feel brand new again.
What to Do Immediately After Replacing Your Screen
Before diving into advanced tests, start with a simple visual inspection:
- Look for gaps or misalignment. The screen should be snug and flush with the frame.
- Check for pixel issues or dead zones.
- Ensure there’s no dust or glue residue trapped under the glass.
These small things can become huge headaches later.
Step-by-Step Screen Calibration Guide
Why Calibrate a New Screen?
When your screen is replaced, the touch sensor alignment may be slightly off. That leads to issues like:
- Inaccurate touch response
- Ghost atinge
- Unregistered taps
Manual Calibration Methods
Android:
- Go to
Settings > Display > Touch Sensitivity(dacă este disponibil). - Utilizare Calibrarea ecranului tactil apps like “Reparație ecran tactil” sau “Tester MultiTouch”.
iPhone:
- iOS doesn’t allow manual calibration, but a hard reset sometimes realigns input logic.
When to Seek Professional Calibration?
If you notice:
- Slow touch recognition
- Jittery typing
- Phantom taps
Let a technician recalibrate using special tools or diagnostic software.
Testing Touchscreen Responsiveness
Basic Touch Test
- Swipe across all edges and corners
- Pinch and zoom images
- Draw lines on a drawing app to test continuity
Multitouch Testing
Use apps like “MultiTouch Tester” to see how many fingers your phone detects at once and if any area lags.
Display Color and Brightness Check
Color Accuracy Matters
Is the white really white? Are reds overly saturated? Compare your screen side-by-side with another device.
Adjusting Display Settings
Pe Android:
- Go to
Settings > Display > Color Mode
On iOS:
Settings > Accessibility > Display & Text Size
Apps like “Color Calibrator” (Android) let you adjust RGB manually.
Earpiece, Microphone & Sensor Diagnostics
Earpiece Speaker Test
Make a phone call or play audio to confirm your earpiece is working correctly.
Ambient Light & Proximity Sensors
Cover the top of your phone during a call. The screen should turn off. If not, your proximity sensor might be misaligned.
Gyroscope and Accelerometer Testing
- Open the camera and tilt your phone
- Play motion-based games
- Use tools like “Sensor Box” or “CPU-Z” for advanced tests
Handling Waterproof Seals Post-Screen Replacement
What is Waterproof Glue/Sealant?
This is the black adhesive that surrounds your screen and keeps moisture out. Once your phone is opened, it loses its water-resistance unless re-applied.
Reapplying Waterproof Adhesive
- Clean the phone’s frame thoroughly
- Apply OEM-grade waterproof adhesive (like T-7000 or B-7000)
- Let it cure for at least 24 hours
Can Your Phone Still Be Waterproof?
Maybe. But not like before. The original factory seal is nearly impossible to replicate 100%. Be cautious in rain or near pools.
Final Functional Testing Checklist
Go through this list like a pro:
- ✅ Touch (every inch!)
- ✅ Display (colors, luminozitate)
- ✅ Speaker & mic
- ✅ Front & rear camera
- ✅ Proximity and light sensors
- ✅ Face ID/Fingerprint
- ✅ Volume and power buttons
Long-Term Care Tips for Replaced Screens
Use a Screen Protector
Tempered glass isn’t overkill—it’s a lifesaver for your new screen.
Avoid Extreme Temperatures
Heat weakens glue. Cold makes the screen brittle. Keep your phone within a comfy range.

- You see internal fogging
- Your screen lifts at the corners
- Touch problems persist
… go back to your technician. Rapid.
