Galaxy S20+ Screen Replacement
On the Galaxy S20+ we only sell the screen already fitted in a new frame. Samsung bonds the curved screen to the frame, and trying to separate them usually breaks the new one. Instead, everything inside your phone moves over to the new frame.

Open the back
Power off and remove the SIM tray
Power off the phone and pull the SIM tray. Samsung back glass is thin and bonds hard, so cover it with packing tape if it’s cracked.
Heat the back glass
Warm the edges of the back glass evenly for 3–5 minutes. Samsung uses stronger adhesive than Apple, so expect to reheat a couple of times. Keep the heat moving and away from the camera lenses.
Cut the back glass adhesive
Lift near the bottom edge with a suction cup just enough for a hairline gap, slide a pick in and work it around all four sides, leaving picks in the gap so the adhesive doesn’t reseal. Keep the pick shallow at the top near the cameras.
There is no cable attached to the back glass on these phones, so once the adhesive is cut the glass lifts straight off.
Cut both long sides first, then slide the glass down slightly and cut the top. Remove the wireless charging cover
Remove the Phillips screws around the top plastic cover (it carries the wireless charging and NFC coil) and lift it off. Some models have a bottom cover over the speaker too; remove its screws and lift it off.
Disconnect the battery
Unplug the battery cable first with the flat end of a spudger, before you touch any other cable. Then unplug the long main cable that crosses the battery and links the logic board to the charging port board.
Battery off first and back on last, so the phone stays dead while cables are moving. Schematic, not to scale.
Move everything to the new frame
Lift out the boards and cameras
Unplug the display cable, the antenna cables and the camera cables from the logic board, remove its Phillips screws and lift the board out by its edges. Lift the rear cameras out of the frame. Then unplug and remove the charging port board at the bottom and the loudspeaker.
Move the small parts
Move the vibration motor, the earpiece if it isn’t on the logic board, any rubber gaskets and the antenna cables over to the new frame. Check the new frame has its side buttons fitted; if it doesn’t, move the button cable across too.
Soften the battery adhesive
The battery is glued to the frame with no pull tabs on most of these models. Drip isopropyl alcohol along the edges of the battery and let it soak in for a minute or two. If your battery does have pull tabs, use them instead.
Lift the battery out
Starting from the bottom edge, slide a plastic card under the battery and lift slowly, adding alcohol as you go. Never use metal, never bend the cell, and stop if it swells, smokes or smells. Put the old battery straight into a metal can of sand.
Fit a new battery in the new frame
A battery that has been pried out is often bent, so use a new one. Apply fresh adhesive and press the battery into the new frame.
Reassembly
Rebuild in the new frame
Fit the charging port board, the loudspeaker, the logic board and the cameras into the new frame in the same order they came out. Reconnect every cable, then plug in the main cable and the battery last. Refit the covers and their screws.
Test before you close
Power on and check the screen, touch, both cameras, the speakers, charging and the side buttons. Re-register your fingerprint in Settings.
Close the back
Clean the back glass, lay new back glass adhesive, press the glass onto the new frame and clamp it for several minutes. Slide the SIM tray back in.
