Use this guide to remove a broken or defective LCD & Digitizer in your Sony Xperia Z4.
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.
Due to the phone’s design, you must remove the lithium-ion battery to access the display cables. If the battery was deformed during removal replace it with a new one—reusing a deformed battery is a potential safety hazard.
Before disassembling your phone, discharge the battery below 25%. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged.
Note: This guide instructs you to replace only the screen while leaving the original frame and motherboard in place. However, some replacement screens for this phone come pre-installed in a new frame (a.k.a. chassis), which requires a very different procedure. Make sure you have the correct part before starting this guide.
You’ll need replacement adhesive to reattach components when reassembling the device.
