Google Pixel 7a – Full Teardown & Step-by-Step Repair Guide

---

OVERVIEW:

In this Tech Dep teardown, we open up the mid-range Google Pixel 7A to take a detailed look inside. While this device boasts a solid build and Gorilla Glass protection, its OLED display proves delicate during disassembly, requiring extreme care. The teardown involves removing the fragile front screen, accessing the internal components from the back, and working through extensive adhesive. The Pixel 7A is designed with many tightly packed and soldered components, making precision essential throughout the process. As always, we use the best tools and techniques to ensure safe disassembly without causing damage.

REPAIR TIME & SKILL LEVEL:

This repair is estimated to take about 1.5 to 2 HOURS to complete and is of INTERMEDIATE difficulty, requiring careful handling of delicate parts and attention to flex cables and adhesive.

STEPS:

Tools You Need

For this repair, you will need a heating mat set between 75 to 85 degrees Celsius (specifically 77°C in this case), a suction cup tool to lift the screen, playing cards and an eye opener tool to work through the adhesive, a curved screen disassembler for precision, isopropyl alcohol (99%) to weaken the glue, and both T5 and T2 screwdrivers to remove internal screws.

---

Prepare the Workstation

• Set the heating mat to 77°C to begin loosening the adhesive beneath the screen.
• Organize all necessary tools to ensure smooth workflow during disassembly.
• Power off the device completely before beginning any work.

---

Begin Lifting the Front Screen

• Use the suction cup tool to apply gentle upward pressure to the screen.
• Slowly insert a playing card into the gap created by the suction cup.
• Insert the eye opener tool alongside the card to help cut through the adhesive carefully.

---

Work Around the Edges

• Slide the card and tool along the screen’s perimeter to loosen all adhesive.
• Exercise patience—OLED screens are very fragile and prone to damage.
• Apply isopropyl alcohol (99%) to the edges to assist in breaking down the glue.

---

Carefully Open the Screen Like a Book

• Once the adhesive is sufficiently loosened, open the screen from one side like a book.
• Be cautious of the screen’s hinges and flex cables still connected inside.
• Do not force the screen—resistance indicates more adhesive or an attached cable.

---

Disconnect the Screen Flex Cable

• Locate the screen flex cable secured by a LEGO-style connector.
• Gently pop off the connector to fully detach the front screen from the device.
• Set the screen aside on a soft surface to avoid scratches or further damage.

---

Observe Internal Components

• Note the placement of the fingerprint scanner beneath the screen’s center.
• Spot the proximity and light sensors embedded behind a panel near the center.
• These components are not cameras—contrary to some early speculation.

---

Remove the Back Glass

• Flip the phone over and begin working from the rear glass side.
• This Pixel design is similar to the iPhone 14, where the back gives access to most components.
• Be aware of the adhesives securing the back panel.

---

Unscrew the Internal Panel

• Remove approximately 15 T5 screws and 2 smaller T2 screws securing internal shields.
• Keep the screws organized for reassembly—Google uses a variety of screw sizes.
• This step grants access to internal components such as speakers and motherboard.

---

Inspect the Wireless Charging Pad

• Identify the wireless charging coil near the center of the phone.
• Note that it charges at a modest 7.5 watts, which is low by modern standards.
• While it supports wireless charging, it’s more suited for idle usage rather than active use.

---

Remove the Top Speaker

• Carefully detach the top speaker from its seated position.
• Use a plastic spudger or tweezers to lift it out without damaging nearby components.
• This piece connects with the lower speaker to form the stereo audio system.

---

Analyze the Motherboard

• Observe the motherboard’s compact and delicate structure.
• Key components like the charging port and front camera are soldered to the board.
• Avoid pulling or lifting until all connected flex cables are fully disconnected.

---

Identify Remaining Internal Components

• Remaining parts within the frame include the bottom stereo speaker, vibration motor, battery, and antenna lines.
• Each part is tightly packed, mirroring the layout of more expensive Pixel models.
• Handle all components gently, especially around soldered areas and the battery zone.

---

CONCLUSION:

The Pixel 7A may be Google’s mid-tier phone, but it’s built with precision and complexity. Removing the screen and accessing the internals requires careful heat application, patience, and the right tools. Though some components are modular, several key parts are soldered to the motherboard, increasing the challenge. Google’s design borrows cues from Apple’s recent models, especially in back-glass access. Overall, this teardown is insightful for repair enthusiasts who want to learn the layout and limitations of modern mid-range smartphones.
