Introduction

Opening the Sony Xperia Z4 will damage the waterproof seals on the device. If you do not replace the adhesive seals, your phone will function normally but will lose its water protection.

You’ll need replacement adhesive to reattach components when reassembling the device.

What you need

Step 1

              Back Cover

Before you begin, switch off your phone.
Apply a heated iOpener to the back of the phone to loosen the adhesive beneath the back cover. Apply the iOpener for at least two minutes.

Step 2

Secure a suction handle to the bottom of the back cover, as close to the edge as possible.

Insert an opening pick into the gap.
If you have trouble, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
