How To Check If Your Phone Screen Is Phyiscally Damaged?

Is your phone screen acting up? Before you panic,Let's figure out if it's a software glitch or actual hardware damage. Here's a simple step-by -step guide to diagnose screen issues at home.

Step1:Basic checks
1.Restart Your Phone
 A frozen screen might just need a hard reset.

2.Remove Screen Protector/case
A poorly fitted temered glass or case can block touch sensitivity. Try using the phone without them.

3.Look for Physical Damage
Crack/Spots--Broken LCD/LED panel
Flickering/ Discoloration?--Possible screen or GPU issue
Black screen but phone turns on?--Could be blacklight failure.

Step2: Test Touchscreen Issues
1.Check Touch Sensitivity
Draw lines across the screen (use a drawing app or Touch screen test app)
Dead zones?--Touch sensor damage.
Ghost touchers?-- Moisture of faulty digitizer.

2.Boot in Safe Mode(Check for App conflicts)
If touch works fine here, a third-party app is likely interfering.

Step3:Test Display Problems
1.Check for Display Glitches
Lines/ color distortion?--Damaged screen or GPU
Burn-in --Permanent image retention (needs replacement).

2.COnnect to External Display
Use USB-C/HDM to plug into a monitor/TV.
External display works?-Your phones screen is faulty.
No signal?-Possible motherboard/ GPU issue.

Step4:Advanced Checks
1.Reseat Screen Connector (If You can Open the Phone)
Gently disconnect and reconnect the screen 's flex cable (may fix loose connections)

2.Swap with a Known-Good Screen 
If you have a spare screen , test it-if it works, you original screen is dead.
