Samsung Galaxy A40 Screen Replacement Guide
Duration: 45 minutes
Steps: 25 Steps
Get ready to breathe new life into your Samsung Galaxy A40 with a brand new screen. If the frame is damaged, replacing it is crucial to ensure the new screen fits perfectly and doesn’t get damaged from uneven pressure. Before you start, make sure to discharge your battery to below 25% to minimize the risk of it catching fire or exploding if accidentally punctured. Note that this guide is designed to replace the screen while keeping the original frame and motherboard intact. However, some replacement screens come with a new frame, which requires a different approach. Double-check that you have the correct part before starting. You’ll also need some replacement adhesive to reattach components when putting everything back together. If you need help, you can always schedule a repair.
Step 1
When putting the cards back, just remember to line them up right in the tray for a smooth fit!

– Give that SIM card eject tool a firm push to pop out the SIM card tray like a pro.

If the back cover of your phone is a bit worse for wear, the suction handle might not have the best grip. No worries! Give it a shot with some sturdy tape, or get creative and use superglue to hold the suction handle in place while it sets. Then you’ll be good to go!
Having a tough time creating that gap? Just apply a little more heat to help soften the adhesive a bit more. Make sure to follow the iOpener instructions to keep everything nice and safe from overheating.
