Step 1

Take a look at the Galaxy S9 in the pictures! Our Note 8 was playing hide and seek with its screen, so we had to improvise. Let’s get started on this repair journey together!

– First things first, let’s power down your device! Press and hold that power button until you see the ‘Power off’ option pop up on your screen.

– Now, give it a gentle tap with your finger to confirm that you really want to turn off your Galaxy Note 8. Sit tight and watch as the screen fades to black!

Step 2

– The back cover is really stuck to the chassis, but don’t worry! Just warm up your device evenly with some hot air to loosen that glue up. A cozy temperature of 60 – 80°C should do the trick. Remember, it should still be cool enough to touch comfortably.

– To make things easier, grab a flat and flexible tool like the iPlastix or iFlex. You’ll also want a few picks handy to gently pry the back cover loose all the way around. You’ve got this!

Hey there! Just a friendly reminder to handle that back cover with care—it’s a bit delicate and can crack easily. If you find it stubborn, don’t hesitate to warm it up a couple more times and give it another go. Removing the back cover might take a bit of time, around half an hour, so take it slow and steady to avoid any mishaps. You’ve got this!

The iPlastix is crafted from plastic, so it’s gentle on your device and won’t leave any scratches. However, it can be a bit soft and a little tricky to get in there. If you need help, you can always schedule a repair!
