Hey there! Just a heads up: once you crack open your device, that nifty IP certification (your shield against dust and water) will be waving goodbye. Keep that in mind while you work your magic!
Get ready to crank up the volume on your S21 5G by swapping out the speaker! Our easy-to-follow photo guide will walk you through the process step by step, making it a breeze to bring back that glorious sound. If you need help, you can always schedule a repair.
Step 1
Before diving into the repair of your Galaxy S21 5G, take a moment to run through our handy checklist to test its basic functions. This way, you can easily see if your repairs hit the mark afterward. Let’s get started!
– Give that side and volume down button a nice long press together for a few seconds! You got this!
– Once the menu pops up, tap on Power off and confirm with your unlock code. Easy peasy!
Watch out for those sizzling fingers! Heat the back cover just enough so you can still give it a friendly tap. Keep it cool, and if you need help, you can always schedule a repair.
The back cover is stuck on there pretty tight with some serious adhesive. So, before you dive in, give it a good warm-up! Grab your hot air device—whether it’s a heat gun or your trusty hair dryer—and let’s get that cover nice and toasty!

To create a snug little space between the back cover and the display unit, grab yourself a flat and stable tool. We suggest the iFlex for this task, as its super sharp edges make it a breeze to slide in!
– Grab a suction cup and stick it to the bottom edge of the back cover, then gently pull it up. At the same time, slide the iFlex tool between the display unit and the back cover to help separate them.

Hey there! Just a quick heads-up: when you’re working on that camera module, be gentle and don’t go too deep with your tool. We suggest using a hard plastic pick here—it’s designed to keep you from going overboard. Happy repairing!
To keep the edges of your device safe from the sharpness of the iFlex, it’s a smart move to switch to a plastic tool like the iPlastix as soon as you can. Your device will thank you!

If things aren’t quite right during testing, take a moment to ensure that everything is snug and securely hooked up. A little TLC can go a long way!
– Fire up your Galaxy S21 and get ready to roll!
– Dial in the Samsung test menu with *#0*# in your phone app.

Step 19
Adding a new adhesive frame is totally up to you! If your current one is looking good and sticking like a champ, there’s no need to swap it out. But if it’s showing signs of wear or isn’t holding on as it should, we suggest going ahead and putting in a fresh adhesive frame. Remember, a little extra stickiness can go a long way!
Step 20
– Wrap up your Galaxy S21 5G repair by gently pressing the back cover back onto the display unit. You’re almost there!
Give that back cover a little extra love! Run some hot air along the edge to help the glue stick like it means it. If you want to keep things cozy, try stacking some books on your device for a few minutes or give it a gentle clamp, just like we show you in our example. Remember, if you need help, you can always schedule a repair.
