はじめに

Use this guide to replace a cracked or broken screen in your Samsung Galaxy A50.

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.

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.

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

  1. Insert a SIM card eject tool, a SIM eject bit or a straightened paper clip into the hole on the SIM tray located at the left side of the phone. Press firmly to eject the tray. Remove the SIM card tray.

    • Heat an iOpener and apply it to the back cover to soften the adhesive.

    • The adhesive of the Samsung Galaxy A50 is very strong. A hair dryer, heat gun, or hot plate may also be used if you aren't able to open the device with the iOpener. Be careful not to overheat the phone—the AMOLED display and internal battery are both susceptible to heat damage.

  3. Insert an opening pick at the bottom of your phone near the USB-C port. If you can't get between the back cover and midframe with your opening pick, you can use a suction handle or strong tape to pull up the back cover to create a gap. Slide the opening pick to the bottom left corner.

終わりに

If possible, turn on your device and test your repair before installing new adhesive and resealing.

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.

To reassemble your device, follow these instructions in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

Take your e-waste to an R2 or e-Stewards certified recycler.

considering it is embedded within the display assembly, any chance that the fingerprint sensor is affected by replacing the screen?

Steve B - 返信

Hi Steve, the fingerprint sensor is not embedded within the display as you can see here. The sensor is fixed under the frame and can be seen through the hole in the frame.

Hey, I followed this procedure to replace my screen and now, whenever I am charging my phone it keeps on rebooting itself every 3-5 seconds, or even when it’s not charging and is just idle. I tried to open it up and realign everything however it didn’t help and kept rebooting. So I am not quite sure what I did wrong and was wondering if you have ever experienced that, and what to do about it.
