Duration: Let's aim for about 90 minutes to wrap up this repair adventure!
Steps: 24 Steps
We're here to walk you through the fun process of swapping out your Samsung Galaxy A70's display, step by step! From popping off that back cover to carefully removing and reinstalling each little part, we've got you covered. A cool thing about the Galaxy A70 is its back cover—it's made of tough plastic instead of glass, so it's less likely to get damaged during your repair adventure! If you hit any snags along the way, feel free to reach out to our awesome support team via chat or comments—we're always happy to help! And hey, we love hearing your thoughts, so don't hold back on the feedback! Now, let's get started and have a blast fixing up your Galaxy A70!
Step 1
- Give your Galaxy A70 a little nap by pressing and holding the power button for a few seconds until it switches off.
Step 2
The majority of the adhesive is located in the upper and lower regions of the back cover.

Step 3
- Once you've warmed up the edge of your device, grab a suction cup and stick it on the lower part of the back cover. Give it a gentle pull upwards to create a little gap between the back cover and the center frame. While you're at it, slide a sturdy, flat tool into that gap. We suggest using the iFlex or the iPlastix for this part.
Be careful not to poke your tool too deep into the device—let's keep those components and flex cables safe and sound!
The iFlex is crafted from sturdy metal, giving it a sharp edge that’s perfect for those tricky spots. On the other hand, the iPlastix is made from flexible plastic, making it a gentler option with smoother edges. To keep your device looking pristine, we suggest kicking things off with the iFlex in this step and switching to the iPlastix as soon as you can. Let's keep it scratch-free!
