Introdução
Use this guide to replace a cracked or broken screen in your Samsung Galaxy A50.
Note: The function of the fingerprint sensor might be lost after this screen replacement. Security patches installed after September 2020 don’t support this repair.
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.

considering it is embedded within the display assembly, any chance that the fingerprint sensor is affected by replacing the screen?
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.
sounds like you may have damaged the battery in some way, try replacing the battery!
