はじめに
Use this guide to replace a cracked or broken screen on your Samsung Galaxy A72.
If the frame is deformed, it's important to replace it to make sure the new screen will mount correctly and won’t suffer damage from uneven pressure.
If your battery is swollen, take appropriate precautions. Before disassembling your device, 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.
If you do not replace the adhesive seals when reassembling, your device will function normally, but will most likely lose its water protection.
You’ll need replacement adhesive to reattach components when reassembling the device.

If possible, turn on your device and test your repair before installing new adhesive and resealing.
Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.
To reassemble your device, follow these instructions in reverse order.
The best way to secure the new screen is to apply a sheet of custom-cut double-sided tape to the back of the screen.
Take your e-waste to an R2 or e-Stewards certified recycler.
