Back Glass Replacement vs Full Housing Replacement in Smartphones: Key Differences and Step-by-Step Process

Smartphones are an integral part of our daily lives. However, accidental drops or wear and tear can damage their outer bodies. Two common types of repairs are back glass replacement and full housing replacement—but which one do you need? At TF2SS Ltd, we offer expert mobile repair services, and in this blog, we’ll explain the key differences and guide you through both processes.

Understanding the Basics

What is Back Glass Replacement?

The back glass is the rear panel of a smartphone, typically made of glass in modern devices for wireless charging and aesthetics. It can crack or shatter upon impact, though the internal components usually remain unaffected.

Best for:

• Cracks or shatters on the back glass

• Cosmetic improvements

• Retaining original frame and internal components

What is Full Housing Replacement?

The full housing includes not just the back panel, but the entire external body of the phone—frame, side buttons, and sometimes internal mounting structures. It is a more intensive repair.

Best for:

• Severe frame damage

• Bent or warped casing

• Buttons or structural components not working properly

• Restoration of structural integrity

🛠️ Step-by-Step: Back Glass Replacement

1. Power Off the Phone
   Always shut down the device before any repair.

2. Heat the Back Panel
   A heat gun or pad loosens adhesive beneath the glass.

3. Remove the Cracked Glass
   Using a suction tool and prying tools, carefully lift and remove the broken glass.

4. Clean the Surface
   Remove any adhesive residue and clean the surface thoroughly.

5. Apply New Adhesive
   Use OEM-grade adhesive or pre-cut adhesive tape.

6. Install New Back Glass
   Align properly and press firmly to seal.

7. Final Test
   Power on the device to ensure no functional issues.

 Step-by-Step: Full Housing Replacement

1. Power Off and Remove SIM Tray
   Begin with a complete shutdown and remove external components.

2. Disassemble the Device
   Carefully remove the back panel, screen, battery, motherboard, and other internals.

3. Transfer Components
   Move all internal components from the old frame to the new housing.

4. Install New Housing
   Assemble the internals into the new frame.

5. Reconnect Display and Battery
   Test each component before sealing the device.

6. Seal and Test Device
   Power on the device, check buttons, camera, sound, and other features.

When Should You Choose One Over the Other?

• Choose Back Glass Replacement if:

  • Only the rear panel is damaged

  • The frame is intact

  • You want a cost-effective solution

• Choose Full Housing Replacement if:

  • The frame is bent, dented, or damaged

  • Buttons are malfunctioning

  • You want a complete device refresh
