Make sure your battery is below 25% before diving in!
Ready to give your Samsung Galaxy A40 a fresh start with a new battery? Awesome! Just keep in mind, if your battery looks a bit puffy, it’s time to be super safe. Make sure to drain your battery to below 25% before diving in. This little step helps avoid any unexpected surprises if the battery gets a bit cranky during the repair. And don’t forget, you’ll want some replacement adhesive on hand to stick everything back together when you’re done. If you need help, you can always schedule a repair.
Step 1
When you’re popping those cards back in, make sure they’re lined up perfectly in the tray. If you need help, you can always schedule a repair.
– Grab a SIM card eject tool, a SIM eject bit, or even a straightened paper clip and gently poke it into the little hole on the SIM tray on the left side of your phone.
– With a little bit of pressure, push your SIM card eject tool into that hole to pop the SIM card tray right out.
– Now, carefully lift out the SIM card tray and set it aside.

If the phone’s back cover looks a bit banged-up, your suction tool might play hard to get. Fear not! Try using strong tape to lift it, or if you’re feeling all MacGyver-like, superglue the suction gizmo in place. Just give it time to set, and you’re good to go!
Having a hard time making a gap appear? No problem! Heap some more heat on there to soften up that stubborn adhesive. Just remember to follow the iOpener guide like a pro, so you don’t overdo it. Need a hand? Feel free to schedule a repair.
– Grab a suction handle and latch it onto the right edge of the back cover, keeping it snug near the edge.
– Give it a good pull to lift the back cover just enough to create a tiny gap between it and the frame.
