A Quick Look at the Samsung Galaxy S21 Plus Screen

The Galaxy S21 Plus boasts a stunning 6.7-inch Dynamic AMOLED 2X display, renowned for its vibrant colors, deep blacks, and responsive touch input. However, this beautiful screen is also delicate, making it susceptible to cracks and breaks.

A broken screen can manifest in various ways:

  • Cracked glass: This is the most common type of damage, where the glass surface is spiderwebbed with cracks.
  • Black spots: Dead pixels can appear as dark spots on the screen, indicating damage to the display itself.
  • Touchscreen issues: If the touchscreen becomes unresponsive or erratic, it could indicate damage to the digitizer layer, which translates touch inputs to the phone.
  • Vertical or horizontal lines: These lines often signal damage to the display panel, leading to distorted visuals.

The Right Tools for the Job

Before we delve into the step-by-step instructions, let's gather the essential tools for a smooth and successful screen replacement:

  • Phillips head screwdriver: This will be used to remove the screws securing the phone's components.
  • Heat gun or hairdryer: This will help soften the adhesive holding the back cover and other components in place.
  • Plastic opening tool or guitar pick: This is crucial for gently prying open the phone and separating components without damaging them.
  • Suction cup: This will help you safely lift the screen away from the phone body.
  • Tweezers: These will be helpful for delicate tasks like removing screws and handling small components.
  • Microfiber cloth: A clean cloth is essential for wiping away dust and fingerprints.
