    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.[br]
    [br]
      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 [[E-Waste|R2 or e-Stewards certified recycler|new_window=true]].
